DTLS handshake with and without hello verify request

by Ankita Hatmode

Hi Team, I am working on exploring DTLS handshake using the mbedtls-3.6.4 version on our embedded platform. I enabled the hello verify request feature and got stuck at hello verify request state on server side if I don't reset the ssl context and don't set the client transport ID. I want to know if there is any way to complete a handshake by bypassing the reset of ssl context and setting the client transport ID. Also, our environment only supports C89 constructs. I could not see inttypes.h in the mbedtls-3.6.4, is there any specific reason to remove this file? I am getting compilation errors without inttypes.h and stdint.h. Is there any macro to be enabled to support the c89 compilation in mbedtls stack? Looking forward to your response.

TLS 1.3 and brainpool curves

by Maren Konrad

Dear MbedTLS maintainers, we are already using MBedTLS, however, we recently enabled TLS 1.3 and found that our certificates doesn't work anymore, because they are brainpoolP256r1 (https://datatracker.ietf.org/doc/html/rfc8734). So the question would be, if I missed any configuration to enable the usage of brainpool curves (which are working for TLS 1.2) or if there are any plans, that these are getting supported by MBedTLS 3.6.x? Best regards, Maren Konrad

TLS handshake error : unexpected eof

by kavitha bk

Hi We migrated from mbedtls 2.28 to mbedtls 3.6.2 https://github.com/Mbed-TLS/mbedtls/tree/107ea89daaefb9867ea9121002fbbdf926… and we see TLS handshake fails when we use TLS 1.2 in mbedtls 3.6.2 instead of 1.3. We get below error 20E094B0FFFF0000:error:0A000126:SSL routines:ssl3_read_n:unexpected eof while reading:/usr/src/debug/openssl/3.1.0-r0/ssl/record/rec_layer_s3.c:303: # openssl s_client -connect 192.168.142.1:7001 -no_tls1_3 fails After seeing the trace we have enabled ciphers but still we see the issue. please advise, thanks.

by kavitha bk

Hi all, We are trying to write a psa crypto driver for imx-smw . They have exposed psa certified public apis https://github.com/nxp-imx/imx-smw/tree/release/version_4.x/public/psa Is there any documentation to replace existing psa implementation to custom psa crypto implementation in mbedtls..Please advise on the approach to follow to call the custom apis to implement based on https://github.com/Mbed-TLS/mbedtls/blob/mbedtls-3.6/docs/psa-driver-exampl… Thanks Kavitha

Credential validation BEFORE first TLS handshake: the present and future of mbedtls_pk_sign/verify()

by Almut Herzog

Hi, Prior to the first TLS handshake our application is required to perform input validation of the provided credentials (from file or smart card) for this peer. One of those checks is to verify that private and public key match. We used to use mbedtls_pk_sign() with a custom mbedtls_pk_context for that. But in version 3.X mbedtls_pk_info_t was made private so mbedtls_pk_setup() with a custom mbedtls_pk_info_t whose sign_func would call into our smart card wrapper is no longer possible. Is there still a way to provide custom callback functions for signing in 3.6.4 somehow? Or any other workaround for early check of a key pair? Looking at 4.0.0-beta, also pk.h is no longer public. Will it still be possible to perform early validation of this peer's credentials prior to a first TLS handshake? How? While I am at it, it would be good to implement something that is future-proof. What else I have looked at: * mbedtls_pk_setup_opaque() might be the way to go but I do not find an example of how to link a key id to a custom signature function. * mbedtls_pk_setup_rsa_alt() would be useful if our application was always using RSA. * Both functions are no longer public in 4.0 Related: Early validation of a CRL (whether it was signed by the expected CA) used to be possible with mbedtls_pk_verify_ext(). But to properly set the input parameters requires access to private members of mbedtls_x509_crl in 3.6.4 (maybe an acceptable move?) but in 4.0.0 mbedtls_pk_verify_ext() is no longer public. How perform explicit/"manual" CRL validation especially given the possibly skipped CRL validation in mbedtls_x509_crt_verify() as per the comment below? "It is your responsibility to provide up-to-date CRLs for all trusted CAs. If no CRL is provided for the CA that was used t sign the certificate, CRL verification is skipped silently..." Any future-proof ideas for this? Best regards, /Almut

imx-secure-enclave with mbedtls 2.28.9

by kavitha bk

Hi We are using mbedtls 2.28.9 and want to offload crypto operations to HSM from NXP imx-secure-enclave. is the below approach correct or please suggest alternate approaches if any? 1.Transition all apis from traditional apis to psa in modules Use PSA crypto module https://github.com/Mbed-TLS/mbedtls/blob/development/docs/psa-transition.md 2. Integrate PSA module with imx-secure-enclave in our custom mbedtls 3. All modules will use custom mbedtls which will internally offload crypto operations to HSM or Do you recommend to use MBEDTLS_PK_RSA_ALT_SUPPORT? and implement the key creation/signing/export of public key operations ? Thanks, Kavitha

Question about partial certificate chains

by Roman Janota

Hello, I have the following two certificate chains: server <- intermediateCA <- rootCA and client <- intermediateCA <- rootCA. Currently there are two ways the client is authenticated by the server: both the intermediateCA and rootCA certificates are configured as CAs on the server or if only intermediateCA is configured. I am using a custom verify callback set by mbedtls_ssl_conf_verify(). I would like to achieve two separate cases: 1) Make the MbedTLS' built-in pre-verify be successful, even when only the rootCA certificate is set as the server's CA. 2) Always obtain the whole certificate chain up to the root in the verify callback. For case 1) this is how our OpenSSL TLS implementation works, it is discussed here <https://github.com/openssl/openssl/issues/7871>. From my understanding the server should be able to build the certificate chain by inquiring the client about its certificate's issuer, etc. For case 2), whenever both rootCA and intermediateCA are configured on the server, only the chain client <- intermediateCA is received by the callback. I would like to be able to receive the chain client <- intermediateCA <- rootCA. Are these two cases achievable with mbedTLS? For reference I am using mbedTLS 3.5.2. For my server I would like to utilize both cases 1) and 2) and for the client only the case 1). Kind regards, Roman Janota

PSA Crypto API version compliance

by Zak, Kevin

Hello, I notice in 'crypto.h' of mbedTLS 3.6.3, PSA_CRYPTO_API_VERSION_MAJOR & PSA_CRYPTO_API_VERSION_MINOR show the version implemented as v1.0. Per the github page of TF-PSA-Crypto (https://github.com/Mbed-TLS/TF-PSA-Crypto/blob/development/README.md), the implementation is of v1.1. I verified that this mismatch between the README and crypto.h exists on the development branch of TF-PSA-Crypto as well. What is the correct version implemented, as of mbedTLS 3.6.3? Regards, Kevin

(no subject)

by Steve Glass

Hi, I'm trying to build the mbedtls v3.6.3 for an embedded 386 device. The build is configured as `crypto_baremetal`. In the snippet below I use the make build process with a GCC 11.2 cross toolchain that's installed in `/opt/x-tools/i386-elf but the build process ends with an error: ``` (venv) dev [ /workspaces/mbedtls ]$ make CC=/opt/x-tools/i386-elf/bin/i386-elf-gcc AR=/opt/x-tools/i386-elf/bin/i386-elf-ar make[1]: Entering directory '/workspaces/mbedtls/library' CC aes.c CC aesni.c CC aesce.c ... CC src/certs.c CC src/psa_test_wrappers.c CC src/test_helpers/ssl_helpers.c make[1]: Leaving directory '/workspaces/mbedtls/tests' make[1]: Entering directory '/workspaces/mbedtls/programs' CC aes/crypt_and_hash.c /opt/x-tools/i386-elf/lib/gcc/i386-elf/11.2.0/../../../../i386-elf/bin/ld: cannot find crt0.o: No such file or directory collect2: error: ld returned 1 exit status make[1]: *** [Makefile:160: aes/crypt_and_hash] Error 1 make[1]: Leaving directory '/workspaces/mbedtls/programs' make: *** [Makefile:34: programs] Error 2 (venv) dev [ /workspaces/mbedtls ]$ ``` So I have two questions: This error says it fails to link find crt0.o but the output (library/libmbedcrypto.a) exists and looks ok (altho I've yet to try linking against it). Is the error message spurious or is the library it produced unusable? Do I really need a version of crt0.o to link successfully? (The same configuration builds with no errors using the host's x64 compiler toolchain - and that toolchain also doesn't have a crt0.o file). Thanks in advance!

Any plan for a Java Binding ?

by Simon Bernard

Hi, I'm the main developer of Leshan Library. This is a Java open source implementation of LWM2M protocol hosted at Eclipse Foundation. We currently use Scandium (from Californium Project) as DTLS library. This library fits our needs until now but we have some concerns about future-proofness of it (Especially, there is no plan for DTLS 1.3) and there is no support of TLS. So we explore some other way for the future. I had consider to use OpenJdk but there is a lot of missing IoT Features. I contact OpenJdk security dev and they makes me understand politely that IoT is not the priority (at least this is my understanding) Another solution we explore would be to use an mbedtls Java binding. (as mbedtls is well supported and focus IoT) There is a not official one at : https://github.com/open-coap/kotlin-mbedtls *Questions : * 1. Is there any official java binding ? 2. If no, is there any plan for that kind of binding ? 3. If no, if there is a community initiative could it be hosted by you ? Thx, Simon

PQC code from European Project QUBIP - Security Pattern

by Alberto Battistello

Hi all, I am writing in behalf of Security Pattern, a security firm specialized in embedded systems. We are a member of the QUBIP European Funded Project (https://qubip.eu), which aims at transitioning protocols, networks, and systems to Post Quantum algorithms. As a result of the project, we have integrated a set of Post Quantum algorithms in the TLS1.3 stack of the MbedTLS code (see here https://github.com/QUBIP/pq-mqtt-client-mbedtls). We have code running on STM32 Nucleo board in two versions: the former is a full software, by leveraging the crypto primitives provided in a library developed by another partner, the latter using a Secure Element emulated by FPGA connected via I2C (also developed by another partner of QUBIP). Our main work has beed dedicated to integrating the new hybrid KEM and signatures (MLKEM768-x25519 and MLDSA44-Ed25519) into the TLS stack, in order to demonstrate communication with an MQTT broker running OpenSSL. At the current stage we are about to publish the code on github with MIT license (here https://github.com/QUBIP/pq-mqtt-client-mbedtls). Meanwhile, we think the effort we made could be of help for MBedTLS development/developers. So I would like to ask if you can address me to some contact that is responsible in MbedTLS or ARM about the PQC transition or the best way to facilitate the use/integration of our work.

handshake fail with "Alert (Level: Fatal, Description: Protocol Version)"

by 扶柏成

Hi all, We have encountered a challenge while using mbedTLS 3.5.1 and would greatly appreciate the assistance of the experts. Thank you in advance for your support. I used mbedTLS 3.5.1 to connect to the server acc.connect.cpms.milence.com, and the TLS handshake failed with an Alert (Level: Fatal, Description: Protocol Version) error. Detailed information is described at this GitHub issue<https://github.com/Mbed-TLS/mbedtls/issues/10141>. * We attempted to connect with the Windows EDGE browser and found through packet capture that the handshake was successful. * We were also able to successfully handshake using TLS 1.2. * When we limited the supported group to only: MBEDTLS_SSL_IANA_TLS_GROUP_SECP256R1 and used TLS 1.3, the handshake was also successful. For more details, please refer to the discussion on GitHub: Handshake fail with "Alert (Level: Fatal, Description: Protocol Version)" ・ Issue #10141 ・ Mbed-TLS/mbedtls<https://github.com/Mbed-TLS/mbedtls/issues/10141>.

[Mbed-tls-announce] Announcing Mbed TLS 3.6.3 and 2.28.10

by Gilles Peskine via Mbed-tls-announce

Dear Mbed TLS users, The next release of Mbed TLS (3.6.3 and 2.28.10) is scheduled on Monday 2025-03-24. It will include a security fix for a vulnerability with a high impact to affected applications. Due to the nature of the vulnerability, which involves an insecure default in current versions of Mbed TLS, fixing it may require a small change in application code. We will provide instructions in the release notes. Without this change, affected applications will fail at runtime with Mbed TLS 3.6.3 or 2.28.10. Applications that are currently secure will generally not require any change. We apologize for the inconvenience.

Problem during test_suite generation while cross-compiling on version 3.6.2

by Francois Mace

Hello Everybody, I am trying to migrate my cross-compilation setup from version 2.28.9 to version 3.6.2. I use a Makefile based approach for compilation. Everything seems to work fine up to the point where the compilation process reaches the test_suite data generation Gen suites/test_suite_psa_crypto_generate_key.generated.data suites/test_suite_psa_crypto_low_hash.generated.data suites/test_suite_psa_crypto_not_supported.generated.data suites/test_suite_psa_crypto_op_fail.generated.data suites/test_suite_psa_crypto_storage_format.current.data suites/test_suite_psa_crypto_storage_format.v0.data At that point it seems that the python based tools attempts to execute a temp executable (generated for my cross-compilation target ?) which fails. The traceback obtained is the following: Traceback (most recent call last): File "../framework/scripts/generate_psa_tests.py", line 849, in <module> test_data_generation.main(sys.argv[1:], __doc__, PSATestGenerator) File "/home/dev/test/mbed-TLS_3.6.2/framework/scripts/mbedtls_framework/test_data_generation.py", line 224, in main generator.generate_target(target) File "../framework/scripts/generate_psa_tests.py", line 845, in generate_target super().generate_target(name, self.info) File "/home/dev/test/mbed-TLS_3.6.2/framework/scripts/mbedtls_framework/test_data_generation.py", line 177, in generate_target self.write_test_data_file(name, test_cases) File "/home/dev/test/mbed-TLS_3.6.2/framework/scripts/mbedtls_framework/test_data_generation.py", line 164, in write_test_data_file test_case.write_data_file(filename, test_cases) File "/home/dev/test/mbed-TLS_3.6.2/framework/scripts/mbedtls_framework/test_case.py", line 88, in write_data_file for tc in test_cases: File "../framework/scripts/generate_psa_tests.py", line 694, in all_test_cases if key.location_value() != 0: File "/home/dev/test/mbed-TLS_3.6.2/framework/scripts/mbedtls_framework/psa_storage.py", line 186, in location_value return self.lifetime.value() >> 8 File "/home/dev/test/mbed-TLS_3.6.2/framework/scripts/mbedtls_framework/psa_storage.py", line 89, in value self.update_cache() File "/home/dev/test/mbed-TLS_3.6.2/framework/scripts/mbedtls_framework/psa_storage.py", line 67, in update_cache include_path=includes) #type: List[str] File "/home/dev/test/mbed-TLS_3.6.2/framework/scripts/mbedtls_framework/c_build_helper.py", line 158, in get_c_expression_values output = subprocess.check_output([exe_name]) File "/usr/lib/python3.7/subprocess.py", line 395, in check_output **kwargs).stdout File "/usr/lib/python3.7/subprocess.py", line 472, in run with Popen(*popenargs, **kwargs) as process: File "/usr/lib/python3.7/subprocess.py", line 775, in __init__ restore_signals, start_new_session) File "/usr/lib/python3.7/subprocess.py", line 1522, in _execute_child raise child_exception_type(errno_num, err_msg, err_filename) OSError: [Errno 8] Exec format error: '/tmp/tmp--m95sjmdw' make[2]: *** [Makefile:127: generated_psa_test_data] Error 1 make[2] : on quitte le répertoire « /home/dev/test/mbed-TLS_3.6.2/tests » make[1]: *** [Makefile:35: tests] Error 2 make[1] : on quitte le répertoire « /home/dev/test/mbed-TLS_3.6.2 » make: *** [test.make:152: all] Error 2 Looking at the format of the generated tmp executable, it seems it is generated for my cross-compilation target, it therefore cannot be executed in my compilation environment. I would like to be able to generate the test and test data in order to be able to execute them on my compilation target, which is what I used to do with the previously integrated version of the library. Is there something I am missing in my compilation? am I missing a specific setup variable in my Makefile? Thanks for your feedback. Best regards, Francois

Different performance from 2.6.2 to 3.6.2 for https file upload

by Stefano Tebaldi

Hello, I recently updated mbedTLS library version 2.6.2 to 3.6.2. I am using the library to add https to Mongoose web server on a STM32H753 with FreeRTOS + LWIP. 2.6.2 was generated in a IAR project using STMCubeMX. What I am noticing is that file transfer performance has gotten much worse. With version 2.6.2 it took a few minutes to transfer a file of around 33 MB, now with version 3.6.2 it takes around 15 min. What could this depend on? Attached is the configuration used for the two versions. The certificate for https is EC curve secp256r1. Thank you

[Mbed-tls-announce] Mbed TLS 4.0/TF-PSA Crypto 1.0 release timeline

by Janos Follath via Mbed-tls-announce

Dear Mbed TLS and PSA Crypto users, We would like to update you on the release timeline for Mbed TLS 4.0/TF-PSACrypto1.0 release. As a reminder, the key objectives of the release are a separate TF-PSA Crypto repo., PSA Crypto becoming the de facto Crypto API and Mbed TLS using PSA Crypto APIs as the crypto API by default. While TF-PSA Crypto repository is now available, the remaining effort to be ready for the release is more than we originally planned for. Based on remaining effort estimates, we plan to make Mbed TLS 4.0-Beta and TF-PSA Crypto 1.0-Beta release around end of June. The Mbed TLS 4.0, and TF-PSA Crypto 1.0 release is expected around end of September. We don’t expect users to integrate the Beta release. Beta is aimed to pipeclean the separate Mbed TLS and TF-PSA Crypto release process and get any early feedback. The release in September is expected to be integrated by users to their projects. We wanted to provide these revised release dates so that the users can plan accordingly. In the meantime, bug fixes and security fixes will continue to be provided via. Mbed TLS 3.6.x LTS releases. Thanks, Mbed TLS/PSA Crypto Maintainers. -- Mbed-tls-announce mailing list -- mbed-tls-announce(a)lists.trustedfirmware.org To unsubscribe send an email to mbed-tls-announce-leave(a)lists.trustedfirmware.org

Support for Quantum Safe Algorithms

by NAYNA JAIN

Hi MbedTLS team, I have been following up the MbedTLS roadmap from here - https://mbed-tls.readthedocs.io/en/latest/project/roadmap/ . It talks about Post Quantum Cryptography support in future. And in the section of Long Term Plans for MbedTLS, I see the note related to PQC as "Regarding post-quantum cryptography (PQC) in particular, we do plan to wait until there are official standards: as of 2023, apart from stateful hash-based signatures, there are too many open questions about selected algorithms (choice of parameters, data formats, hybrid combinations…). This note seems to be pretty old as it refers to 2023.. So, are there any latest update on the roadmap? Is there any plan to support latest NIST standardized algorithms (ML-DSA, ML-KEM, SLH-DSA) in this year or next year. Thanks & Regards, * Nayna

Using mbedTLS for TLS&X509 with a separate PSA Crypto Implementation

by Zak, Kevin

Hello mbedtls mailing list, I'm working to modify mbedTLS (3.6.2) to use our PSA Crypto Implementation in a separate library. Our solution does not make use of PSA 'drivers' that mbedTLS refers to. I've modified makefiles to not build PSA Crypto files, and have enabled MBEDTLS_PSA_CRYPTO_C & MBEDTLS_USE_PSA_CRYPTO. I've also defined MBEDTLS_PSA_ACCEL_ALG_XXX for our supported algorithms. 1. Is there a good way to determine whether a given TLS/X509 configuration would require a certain 'legacy' (maybe a better term is 'non-PSA') crypto file to be built into the mbedTLS library? * The goal is to build as few crypto source files into the mbedTLS source files as possible, maximizing usage of our separate PSA implementation 2. Example: My test application using mbedtls_x509_crt_parse() receives linking errors for mbedtls_ecp_(group/point)_xxx() and mbedtls_mpi_xxx() that are referenced in pkparse.c (which I am building into the library). * Ecp.c is currently excluded from the build (as is its define) - if I add it, I add significantly more linking errors for mbedtls_mpi APIs. I was under the impression that ECP and MPI APIs could be avoided with the correct configuration. * If ecp/mpi helper APIs are needed still for x509, this would be good to know. However, I'd like to avoid usage of MPI APIs that perform actual software calculations. See the screenshot for a list of non-PSA crypto files I am currently building to test with. I imagine I may have to add more incrementally. [cid:image001.png@01DB726D.879014D0] Any insights on this general use case or my ECP troubles with x509 would be appreciated. I plan to extend the strategy as these are the findings from an attempt to use just one x509 API. Best, Kevin Zak

Use mbedtls_gcm_auth_decrypt get wrong tag

by Elva Huang

Dear mbed TLS team, Recently, while debugging my code, I encountered an issue when using the AES-GCM algorithm. I found that when calling the mbedtls_gcm_auth_decrypt interface in version 3.6.1, the calculated tag consistently does not match the input tag. However, when using the same interface in version 2.28.2, the tag is successfully calculated as expected. Below is the demo code we are using: tstSecKeyList g_stPreInterKey = { .u8KeyNum = 5U, .u8IsUse = 1U, .u16KeyLen = 16U, .u16IVLen = 12U, .u16AddLen = 16U, .enuSecType = SEC_AES_GCM, .au8Key = { 0x68U, 0xffU, 0xb7U, 0xffU, 0x5eU, 0xffU, 0x10U, 0xffU, 0x9eU, 0xffU, 0xb8U, 0xffU, 0x01U, 0xffU, 0xb9U, 0xffU, 0xa0U, 0xffU, 0x1cU, 0xffU, 0xdfU, 0xffU, 0x0aU, 0xffU, 0xe6U, 0xffU, 0xc8U, 0xffU, 0xc5U, 0xffU, 0x39U, 0xffU }, .au8Iv = { 0x3, 0x1, 0x2, 0x3, 0x4, 0x5, 0x6, 0x7, 0x0, 0x1, 0x2, 0x3 }, .au8Add = { 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0 } .u16AddLen = 0, }; static uint8_t s_au8SecMemoryBuffer[6*1024]; mbedtls_gcm_context aesGcmContext; uint8_t *pau8EncryptedPlain = inParam0; (note: inParam0=434421d30c9abf31b96d2d28d00b5cb4e6fe84033999d53d3a50674b3aedd81f) uint8_t *pau8AesTag = inParam0 + 16; (e6fe84033999d53d3a50674b3aedd81f) uint8_t u8EncryptedPlainLen = 16; uint8_t u8AesTagKeyLen = 16; mbedtls_gcm_init(&aesGcmContext); mbedtls_memory_buffer_alloc_init(s_au8SecMemoryBuffer, 6*1024); vidPreInterKeyget(g_stPreInterKey.au8Key, au8preInterKey); mbedtls_gcm_setkey(&aesGcmContext, MBEDTLS_CIPHER_ID_AES, au8preInterKey, 16*8); s32Ret = mbedtls_gcm_auth_decrypt(&aesGcmContext, u8EncryptedPlainLen, g_stPreInterKey.au8Iv, g_stPreInterKey.u16IVLen, g_stPreInterKey.au8Add, g_stPreInterKey.u16AddLen, pau8AesTag, u8AesTagKeyLen, pau8EncryptedPlain, s_au8DecryptKey); Best regards,

Question Regarding Change Cipher Spec States in the TLS 1.3 Handshake Protocol

by 千山啼祢

Dear Developer, I was reviewing the code and noticed that in the TLS 1.3 handshake protocol state machine, the "Change Cipher Spec" state has been divided into five different states based on its occurrence timing. Could you please clarify if there are any specific considerations for this approach? Additionally, these states can appear multiple times during a single handshake, which implies multiple "Change Cipher Spec" messages. However, the TLS 1.3 standard suggests that the "Change Cipher Spec" should only appear once in a single handshake. Could you kindly explain the rationale behind this design decision? Thank you for your time and assistance. I look forward to your response. Best regards, XiangDong Li

Heap and stack usage information

by Michael Thomas

Hi, I am trying to determine what would be an optimal stack and heap allocation for mbedtls. I realize this changes with algorithms, some configuration macros for the algorithms as well as concurrency. But is there any information on stack and heap usage that I can use as a starting point? And is there any information on the same for a crypto suite.

Inquiry Regarding mbedTLS v2.16.2 Compatibility for Secure MQTT Connection on STM32CubeIDE

by Noushad

Hello, I am currently working on a project using STM32CubeIDE, where I am leveraging mbedTLS v2.16.2 to establish a secure MQTT connection with a Mosquitto broker on port 8883. During my implementation, I encountered a TLS handshake error with the following details: mbedtls_ssl_handshake failed. -29312 (-0x7280) I would like to confirm if mbedTLS v2.16.2, as provided in STM32CubeIDE, supports secure TLS connections (e.g., Secure MQTT) and is compatible with Mosquitto broker configurations. Additionally, I would appreciate guidance on resolving this error. Here are some specific details about my setup: 1. mbedTLS version: 2.16.2 (as integrated into STM32CubeIDE). 2. Broker: Mosquitto, configured for secure MQTT on port 8883. 3. Issue: TLS handshake fails with the error mentioned above. 4. Certificates: [Specify if you are using self-signed certificates, CA certificates, etc.]. Please let me know if additional information or logs would be helpful for diagnosing the issue. Thank you for your assistance.

Request for Assistance with Iterative Loading and Verification of Built-in Certificates in Mbed TLS

by xiaobing wang

Dear Mbed TLS Support Team, I am currently working on a project using Mbed TLS version 3.6 on FreeRTOS, and I am encountering an issue with handling multiple CA certificates during the TLS handshake process. My device has a set of built-in certificates, and I need to try each certificate one by one to establish a successful connection to my server. However, I am facing difficulties in this process. ### System Information: - **Mbed TLS version**: 3.6 - **Operating System**: FreeRTOS - **Configuration**: Default - **Compiler and Options**: N/A (using default configuration) ### Expected Behavior: The first certificate (e.g., `cdotroot.cer`) cannot be verified by Mbed TLS, while the correct certificate should successfully establish a connection. ### Actual Behavior: Both the incorrect and correct CA certificates fail to establish a connection successfully. ### Steps to Reproduce: Here is a sample of my code: ```c static int load_and_verify_certificates(int conn_id, uint8_t *cert_buffer, size_t buffer_size) { int ret; bool connection_established = false; uint32_t cert_index = 0; while (!connection_established && cert_index < MAX_CERT_COUNT) { size_t cert_size = buffer_size; // Free and initialize the certificate context mbedtls_x509_crt_free(&cacert[conn_id]); mbedtls_x509_crt_init(&cacert[conn_id]); // Load the built-in certificate ret = try_built_in_certificate(cert_buffer, &cert_size, cert_index); if (ret == CERT_ERR_INDEX_OUT_OF_RANGE) { break; } if (ret != CERT_SUCCESS) { cert_index++; continue; } // Parse the certificate cert_buffer[cert_size] = '\0'; ret = mbedtls_x509_crt_parse(&cacert[conn_id], cert_buffer, cert_size + 1); if (ret < 0) { cert_index++; continue; } // Set the certificate chain mbedtls_ssl_conf_ca_chain(&conf[conn_id], &cacert[conn_id], NULL); // Perform the TLS handshake ret = mbedtls_ssl_handshake(&ssl[conn_id]); if (ret == 0) { uint32_t flags = mbedtls_ssl_get_verify_result(&ssl[conn_id]); if (flags == 0) { connection_established = true; // Cache the certificate cache_certificate(cert_buffer, cert_size, cert_index); break; } } else { LOGD("Failed to perform handshake with certificate index %d, error: -0x%x\n", cert_index, -ret); } // Reset the SSL session ret = mbedtls_ssl_session_reset(&ssl[conn_id]); if (ret != 0) { LOGD("Failed to reset SSL session, error: -0x%x\n", -ret); return ret; } cert_index++; } return connection_established ? 0 : -1; } ``` ### Additional Information: Here are the logs: ``` Reading certificate 'cdotroot.cer' at address 0x08100650, size: 1348 Failed to perform handshake with certificate index 0, error: -0x2700 Reading certificate 'digicertroot.cer' at address 0x08100B94, size: 1360 Failed to perform handshake with certificate index 1, error: -0x7300 ... ``` I suspect that the issue may be related to the limited RAM space available on my device. I am looking for guidance on how to properly iterate through and verify the built-in certificates within these constraints. Any suggestions or best practices for handling multiple certificates in such an environment would be greatly appreciated. Thank you for your assistance.

How to use a different mbedtls_config.h file?

by Alexander Slatina

Hello, I described an issue I have here: https://github.com/Mbed-TLS/mbedtls/issues/9867 During compilation it compiles with the wrong mbedtls_config.h even though I set up this part in my CMakeLists.txt: #MbedTLS default START # 1. MbedTLS custom config setup set(MBEDTLS_DIR ${CMAKE_CURRENT_SOURCE_DIR}/mbedtls) set(MBEDTLS_CONFIG_FILE "${CMAKE_CURRENT_SOURCE_DIR}/mbedtls_config.h") add_compile_definitions( MBEDTLS_CONFIG_FILE="${MBEDTLS_CONFIG_FILE}" MBEDTLS_USER_CONFIG_FILE="${MBEDTLS_CONFIG_FILE}" ) set(ENABLE_TESTING OFF CACHE BOOL "Disable mbedtls testing" FORCE) set(ENABLE_PROGRAMS OFF CACHE BOOL "Disable mbedtls programs" FORCE) set(MBEDTLS_DIR ${CMAKE_CURRENT_SOURCE_DIR}/mbedtls) # Add mbedtls build add_subdirectory(${MBEDTLS_DIR}) #MbedTLS END There’s more information on the GitHub link. Thank you in advance. Alex

TF-PSA-Crypto

by Janos Follath

Dear Mbed TLS users, Mbed TLS has contained the reference implementation of the PSA Crypto API since the early days of the standard. This implementation was experimental at first, but over years of development it reached maturity, and the experimental status was removed three years ago (in version 3.6.1.). Shortly after that, in 2022, the TF-PSA-Crypto<https://github.com/Mbed-TLS/TF-PSA-Crypto> repository was created just for the PSA Crypto API implementation to make it more accessible for users only interested in that. This repository was only a mirror of the main one and the development of the PSA Crypto API implementation remained integral part of Mbed TLS. In the background, work has been started to make this repository the place where the development of the PSA Crypto API reference implementation happens. This work has finally been completed and from now on TF-PSA-Crypto<https://github.com/Mbed-TLS/TF-PSA-Crypto> is ready to receive contributions, bug reports and enhancement requests. TF-PSA-Crypto<https://github.com/Mbed-TLS/TF-PSA-Crypto> will now be the development repository for the PSA Crypto reference implementation. Mbed TLS will continue to rely on TF-PSA-Crypto<https://github.com/Mbed-TLS/TF-PSA-Crypto> and will be using it as a submodule. Many thanks, Janos Follath Mbed TLS developer

advice on mbedtls_ssl_context change between v2.16.1 and 3.6.2

by Daniel Webb

Hi, Can you give me a little advice on how v3 works? I've updated our mbed library from 2.16.1 to 3.6.2 which was mostly a very smooth experience, thanks. The one question in my mind relates to making p_bio private in mbedtls_ssl_context *I used to free it before calling mbedtls_ssl_free - is it ok to skip this now? ie:* //mbedtls_net_free((mbedtls_net_context *) m_ssl.p_bio); mbedtls_ssl_free(&m_ssl); *I also used to poll it before calling mbedtls_ssl_close_notify - is ok to skip this now? ie:* //if(mbedtls_net_poll((mbedtls_net_context *) m_ssl.p_bio, MBEDTLS_NET_POLL_WRITE, 0) < 0) // return; int ret; while((ret = mbedtls_ssl_close_notify(&m_ssl)) < 0) { if(ret != MBEDTLS_ERR_SSL_WANT_READ && ret != MBEDTLS_ERR_SSL_WANT_WRITE) return; } It all seems to run just fine like this, but I could really do with some confidence boosting validation of my cavalier commenting. Thank you Daniel

Integrating Mbed TLS with LWIP

by Bas Prins

Dear Mbed TLS team, I am trying to integrate Mbed TLS in our platform: - nxp imx rt 1024 CPU (arm based) - FreeRTOS (10.6) - Lwip (2.2) - Mbed TLS (3.6.2) I am using the LWIP port to Mbed TLS and managed to create an client configuration by supplying a google certificate which I created as follows: openssl s_client -showcerts -connect www.google.com:443 </dev/null 2>/dev/null | openssl x509 -outform PEM > google_root_ca.pem PS: using the true random number generator in our CPU as the entropy source for Mbed TLS. I ran into some issues which I managed to resolve by adding another option in Mbed TLS (found this on a forum which solved the problem): #define MBEDTLS_RSA_C /* required for google's root CA */ #define MBEDTLS_PKCS1_V21 /* required for RSA */ Next I connected our http client to use the TLS configuration and gave it a first spin by trying to send a HTTP GET request to google.com. The TLS handshake failed. I enabled logging in the hope this would give me a direction, but I can't see where things go wrong (until the obvious error -0x7780 (MBEDTLS_ERR_SSL_FATAL_ALERT_MESSAGE)). Can somebody see what goes wrong on the client side, which results in the server deciding to fail the request? Attached the log and will paste it here in the email. ====================== [2024-12-11 09:08:28] 2024-12-10 12:53:35.612 [Info ] [Http] GET from google.com:443 - / [2024-12-11 09:08:28] 2024-12-10 12:53:35.630 [Debug] [Http] 4 - /home/dev/app/thirdparty/mbedtls/library/ssl_tls.c(1327): The SSL configuration is tls12 only.

C448 according RFC7748?

by Tom Strolch

Hello all, I want to use mbedtls-functions for "Shared Secret" according ECDH with C448. First I want to check the test vectors mentioned in RFC7748 (chapter 6.2). But it fails in function mbedtls_ecdh_compute_shared(...) with return value -0x4C80 MBEDTLS_ERR_ECP_INVALID_KEY (please see code below) But up to now I can't find the root cause. Is there a similar example available?

Migrate LWIP mbed TLS port to Mbed TLS 3.6.2 (or later)

by Bas Prins

Dear Mbed TLS team, I am trying to integrate Mbed TLS in our platform: - nxp imx rt 1024 CPU (arm based) - FreeRTOS (10.6) - Lwip (2.2) - Mbed TLS (3.6.2) LWIP supports Mbed TLS when adding defines in their configuration: /* ---------- TLS ------------------------- */ #define LWIP_ALTCP 1 #define LWIP_ALTCP_TLS 1 #define LWIP_ALTCP_TLS_MBEDTLS 1 But, unfortunately this supports an older version of Mbed TLS (I believe 2.2.x). When I try to compile against the Mbed TLS 3.6.2 libraries, I get a bunch of compiler warnings / errors. Most of them are mentioned in the migration guide, but even then, I have a hard time figuring out how to resolve them "the right way". 1. Private fields The migration guide <https://github.com/Mbed-TLS/mbedtls/blob/mbedtls-3.6/docs/3.0-migration-gui…> explains that most structs are now considered private. 1.1: The altcp_mbed module in LWIP relies on the *out_left* field of the *ssl context* struct. /* calculate TLS overhead part to not send it to application */ overhead = state->overhead_bytes_adjust + state->ssl_context.out_left; I am correct that this field is simply not exposed through accessor functions? I can find functions like mbedtls_ssl_get_avail, so I would expect something like mbedtls_ssl_get_bytes_to_write or something like that? 1.2: The altcp_mbed module in LWIP relies on the *start* field of the *ssl session* struct. err_t altcp_tls_set_session(struct altcp_pcb *conn, struct altcp_tls_session *session) { if (session && conn && conn->state) { altcp_mbedtls_state_t *state = (altcp_mbedtls_state_t *)conn->state; int ret = -1; * if (session->data.start)* ret = mbedtls_ssl_set_session(&state->ssl_context, &session->data); return ret < 0 ? ERR_VAL : ERR_OK; } return ERR_ARG; } I also don't know how to obtain this field "the right way". I know this is a bad idea, but it's all I got if (session->data.*private_start)* ... 2. parse key expects a RNG function This is also explained in the migration guide: *Some functions gained an RNG parameterThis affects users of the following functions: `mbedtls_ecp_check_pub_priv()`,`mbedtls_pk_check_pair()`, `mbedtls_pk_parse_key()`, and`mbedtls_pk_parse_keyfile()`.You now need to pass a properly seeded, cryptographically secure RNG whencalling these functions. It is used for blinding, a countermeasure againstside-channel attacks.* Can you please give me some guidance here? I looked for examples in Mbed TLS repo and ended up with this (bold parts are added, using the key_app.c in your repo as leading example): * mbedtls_entropy_context entropy; mbedtls_ctr_drbg_context ctr_drbg; mbedtls_entropy_init(&entropy); mbedtls_ctr_drbg_init(&ctr_drbg); if ((ret = mbedtls_ctr_drbg_seed( &ctr_drbg, mbedtls_entropy_func, &entropy, privkey, privkey_len)) != 0) { // TODO: handle error } * ret = mbedtls_pk_parse_key( conf->pkey, privkey, privkey_len, privkey_pass, privkey_pass_len, *mbedtls_ctr_drbg_random, &ctr_drbg*); 3. The altcp_mbed module in LWIP relies on mbedtls_ssl_flush_output The altcp_mbed module had an include on ssl internal. #include "mbedtls/ssl_internal.h" /* to call mbedtls_flush_output after ERR_MEM */ This header seems no longer part of the library. But the prototype of the function is now part of ssl_misc.h, but I don't think I am supposed to rely on this header either. I have a couple of options: - ignore the compiler warning /home/dev_container/app/thirdparty/lwip/src/apps/altcp_tls/altcp_tls_mbedtls.c:535:5: warning: implicit declaration of function 'mbedtls_ssl_flush_output'; did you mean 'mbedtls_ssl_tls_prf'? [-Wimplicit-function-declaration] 535 | mbedtls_ssl_flush_output(&state->ssl_context); - copy paste the declaration in the LWIP source file - Or.... don't flush any buffers managed by Mbed TLS in the first place? For the last one, I could really use your input. Can you say anything meaningful about the flush (line in bold) In the below function, Is it mandatory? Or can I trust the Mbed TLS will flush the output buffer whenever it needs to get flushed? /** Sent callback from lower connection (i.e. TCP) * This only informs the upper layer the number of ACKed bytes. * This now take care of TLS added bytes so application receive * correct ACKed bytes. */ static err_t altcp_mbedtls_lower_sent(void *arg, struct altcp_pcb *inner_conn, u16_t len) { struct altcp_pcb *conn = (struct altcp_pcb *)arg; LWIP_UNUSED_ARG(inner_conn); /* for LWIP_NOASSERT */ if (conn) { int overhead; u16_t app_len; altcp_mbedtls_state_t *state = (altcp_mbedtls_state_t *)conn->state; LWIP_ASSERT("state", state != NULL); LWIP_ASSERT("pcb mismatch", conn->inner_conn == inner_conn); /* calculate TLS overhead part to not send it to application */ mbedtls_ssl_get_bytes_avail(&state->ssl_context); overhead = state->overhead_bytes_adjust + state->ssl_context.private_out_left; if ((unsigned)overhead > len) { overhead = len; } /* remove ACKed bytes from overhead adjust counter */ state->overhead_bytes_adjust -= len; /* try to send more if we failed before (may increase overhead adjust counter) */ *mbedtls_ssl_flush_output(&state->ssl_context); // Does it make sense this LWIP port is responsible for flushing here??* /* remove calculated overhead from ACKed bytes len */ app_len = len - (u16_t)overhead; /* update application write counter and inform application */ if (app_len) { state->overhead_bytes_adjust += app_len; if (conn->sent) return conn->sent(conn->arg, conn, app_len); } } return ERR_OK; } After applying the changes I mentioned above, the software compiles against Mbed TLS. I haven't dared to run anything, I just want to enjoy this short moment where I have the feeling I achieved something before runtime errors ruin my day :). Many thanks in advance for any reply!

MbedTLS 2.5 vs MbedTLS 3.6

by Michael Khoyilar

Hi Team I am investigating the move from MbedTLS 2.25 to 3.6, however, our client uses the 2.25 currently (looks like they prefer to stay with it) and I need to provide convincing proof to move to 3.6 considering the upgrade issues that might arise. Any suggestions here that is convincing proof to do the migration to 3.6? I would appreciate your comments. Thanks Michael

Trying to integrate Mbed TLS (3.6) with LWIP (2.x)

by Bas Prins

Dear Mbed TLS team, I am at the early steps of trying to integrate Mbed TLS with LWIP for our project (imx rt 1024 NXP micro, arm M7, running FreeRTOS and LWIP). I understand the basics of TLS, but I am far from an expert. Let me first apologise for the lengthy first email. I am afraid to leave out details. Feel free to skip directly to the end marked with: ============================= My questions: ============================= Some background / translation of how I think it (should) work: From a distance, I understand that LWIP has an abstraction layer on their TCP module, which can be used to integrate Mbed TLS. In fact, LWIP already did this, all I need to do is enable some directives (LWIP_ALTCP_TLS and LWIP_ALTCP_TLS_MBEDTLS). The implemented integration assumes a somewhat older version of Mbed TLS, so I have to adjust a couple to cope with the breaking changes from Mbed TLS 2.x to Mbed TLS 3.6.2. But other than that, integrating Mbed TLS would mean: - figure out which options i want to enable in Mbed TLS - cross compile it for our arm toolchain - extend our build scripts to compile against 3 static Mbed TLS libraries - figure out how to read the CA certificates, and provide them to Mbed TLS - test and fail, and hopefully be man enough to solve the challenges ahead... I haven't achieved much yet, but at least I managed to compile Mbed TLS with our toolchain and recompile our project against the linked libraries. This steps fails though, I get a bunch of linker errors : [100%] Linking CXX executable app.axf /opt/gcc-arm-none-eabi/bin/../lib/gcc/arm-none-eabi/13.2.1/../../../../arm-none-eabi/bin/ld:

`mbedtls_ssl_get_max_frag_len' All except the last one are coming from Mbed TSL internally, so I *guess* this means I am missing options? Or maybe I am still having too many? The last one is called from the LWIP integration of Mbed TLS, and I could "sweep this under the carpet" by disabling "MBEDTLS_SSL_MAX_FRAGMENT_LENGTH". But I haven't looked further in what I cause if I do not support "RFC 6066 max_fragment_length extension in SSL" My Mbed TLS configuration: I followed the suggestion of your documentation, and went for a minimal example configuration. Pure on intuition, I went for "config-ccm-psk-dtls1_2.h". Because the file name suggests it brings TSL 1.2 which is basically all I need. I think. I did had to make the following changes in order to be able to compile it: 1. Comment out two defines in order to get rid of module requiring "windows or unix" //#define MBEDTLS_NET_C //#define MBEDTLS_TIMING_C 2. Add a define, again to get rid of the compiler error "require windows or unix" #define MBEDTLS_NO_PLATFORM_ENTROPY After applying these small changes to the include/mbedtls/mbedtls_config.h I was able to cross compile (and link) Mbed TLS with arm-none-eabi toolchain. Once I adjusted the build scripts to lnk against the Mbed TLS static libraries, I finally ended up with the earlier mentioned linker errors. ============================= My questions: ============================= 1. Does my starting point configuration make sense? As mentioned earlier, pure intuition made me try the "config-ccm-psk-dtls1_2.h" configuration example, which after some modifications compiled and produced 3 static libraries. but, this bit in the example header worries me a bit: * Distinguishing features: * - Optimized for small code size, low bandwidth (on an unreliable transport), * and low RAM usage. * - No asymmetric cryptography (no certificates, no Diffie-Hellman key * exchange). * - Fully modern and secure (provided the pre-shared keys are generated and * stored securely). * - Very low record overhead with CCM-8. * - Includes several optional DTLS features typically used in IoT. What does "no asymmetric cryptography" exactly mean? Isn't that the pure basis of TLS altogether? If I want to achieve HTTPS using TLS, is this a good starting point? 2. Undefined references: wrong configuration, or should I supply some of the implementations? As mentioned before, I have quite a few linking errors related to the cipher module. I tried to find answers in the documentation, but came up empty. I assume (again...) that I should be able to get rid of these linking errors by enabling more features in Mbed TLS. But I honestly get lost in #define's. And maybe it's documented somewhere, but I couldn't find it. 3. Root CA provided by me? I assume I *need* to provide at least one root CA for Mbed TLS to be able to verify the public key provided by the server, at some point, right? I would expect some callback I need to implement where such a root CA was read (in my case, i would have to read if from flash). Am I misunderstanding Mbed TLS on this aspect also? Or did I just miss the obvious spot where to Mbed TLS requests a root CA? 4. More examples available for typical microcontroller projects (FreeRTOS/LWIP)? My experience so far is: - Mbed TLS is well documented - LWIP is no longer actively maintained, and lacks documentation in general - Google finds a painful amount of LWIP/TLS integrations which are based on really old implementations of both, which does more harm than good for me - Chat GPT knows everything, even when it doesn't, which is a really great recipe to get on the wrong track... It doesn't seem rather helpful on my integration questions for Mbed TLS/LWIP. Disclaimer: could be that my lack of knowledge is causing gpt to come up with wrong answers of course... I understand that my email is (too?) long, and that the chance somebody will actually find the time to help me out is limited. I expect nothing, I hope for everything :) ANY help is more than welcome. Good references, links to official documentation I missed, or in the best case: answers to my questions/uncertainties. Many thanks in advance. Best regards, Bas

Confirm if there is an upgrade to the PKCS#1 V2.2 standard.

by Elva Huang

Dear mbedtls platform, I would like to inquire whether the PKCS#1 standard in the source code of mbedtls V2.28.2 has been upgraded to V2.2. From which version does mbedtls start supporting PKCS#1 v2.2? Looking forward to your reply, thank you.

Question about contribution of AES hardware support for RISC-V

by Rick Chen

Dear Mbed TLS maintainers, I have surveyed Mbed TLS and know that it has features which can improve AES block cipher performance by hardware instructions instead of SW implementation e.q., AESCE of ARMV8 and AESNI of INTEL. AS far as I know about RISC-V Cryptography extension(Zkne and Zknd), it also supports relevant AES instructions which can accelerate aes key schedule, encryption and decryption process. (https://tools.cloudbear.ru/docs/riscv-crypto-spec-scalar-1.0.0-rc6-20211012…) I want to ask for your opinions and agreement. Is there any willingness to accept this RISC-V accelerated feature idea and contribution to Mbed TLS ? If you agree with it, I would like to prepare a pull request for you to review. Sincerely, Rick

Checking that RSA key and issuer certificate match using mbedTLS 3.x

by Fabian Keil

Hi, I'm currently working on adding mbedTLS 3.x support for Privoxy [0]. Everything seems to be working but I ifdef'ed out the following code in [1] that worked with mbedTLS 2.28.8: /* * Check if key and issuer certificate match */ if (!mbedtls_pk_can_do(&issuer_cert.pk, MBEDTLS_PK_RSA) || mbedtls_mpi_cmp_mpi(&mbedtls_pk_rsa(issuer_cert.pk)->N, &mbedtls_pk_rsa(*issuer_key)->N) != 0 || mbedtls_mpi_cmp_mpi(&mbedtls_pk_rsa(issuer_cert.pk)->E, &mbedtls_pk_rsa(*issuer_key)->E) != 0) { log_error(LOG_LEVEL_ERROR, "Issuer key doesn't match issuer certificate"); ret = -1; goto exit; } As N and E are private now it no longer compiles. Is there a way to implement the check with mbedTLS 3.x? My impression is that the sanity check is overly cautious and we don't have equivalent code for OpenSSL and wolfSSL but I'm curious. Thanks, Fabian [0] <https://www.privoxy.org/> [1] <https://www.privoxy.org/gitweb/?p=privoxy.git;a=blob;f=ssl.c;h=e8007cd9adad…>

Client Certificate Request Question

by Michael Reutman

Hello, I'm running into an issue with using Mbed-TLS on an embedded device of ours and I'm curious if anyone would be able to point me in the right direction. If this is the wrong channel for general use questions, let me know and I'll search elsewhere. As a forewarning, I'm still getting my bearings around the nuts and bolts of Mbed-TLS and network security; apologies if I misstate something or jumble things up. Our device uses Mbed-TLS 3.0.0; ideally I'd like to upgrade this to a newer version, but this version was included in a SDK package for our device and I'd like to get some basic functionality proven out first before trying to reintegrate a newer version into the rest of provided code. The current goal is to get our device to serve a web page over HTTPS with TLS. What we currently see is that the initial hello client and server messages are exchanged without issue, but the connection is rejected after the server requests a certificate from the client. In some browsers, this opens a prompt where you can select a given certificate on the machine; in others, it skips this prompt and sends a response back with an empty certificate. In both instances, the server will return an error and deny the connection. This seems like some sort of user configuration error, given your average web page served over HTTPS on the internet avoids making this request. The literature I've been able to find so far also seems to suggest this request is entirely optional. Is there some option I'm overlooking that makes the server skip asking the client for its certificate and lets connection continue on?

Problem when parsing certificate without Distinguished Name

by Diego Santos

Hi, I'm trying to parse this DER encoded certificate in hex format: 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 This certificate is part of a simple test for this specification https://github.com/libp2p/specs/blob/master/tls/tls.md I'm using this https://github.com/status-im/nim-mbedtls Nim language library wrapper for mbedtls. I don't know the mbedtls version exactly, but the lib is based on this commit https://github.com/Mbed-TLS/mbedtls/tree/09d23786f6fdcb4dfa88aad30c8767bd27…. In my code I use: proc parseUnverified*(derInput: seq[byte]) = var crt: mbedtls_x509_crt mbedtls_x509_crt_init(addr crt) var ret = mbedtls_x509_crt_parse_der(addr crt, unsafeAddr derInput[0], derInput.len.uint) if ret != 0: raise newException(Exception, "Failed to parse certificate, error code: " & $ret) which is a straightforward version of the C code, but ti fails with: Failed to parse certificate, error code: -9186 [Exception] It seems the problem is because the certificate doesn't have the Distinguished Name set. Does it make sense? If this is really the cause of the problem, is there any workaround? Regards.

Need Info : mbedtls_x509_get_sig_alg API

by Satya Prakash Prasad

Hi, We were using old MBed TLS version 2.19.1 and existing trusted CA certificates were working fine in that release. Recently we upgraded to 3.6.0 and see that now certificate parsing is returning -ox262e value from function mbedtls_x509_get_sig_alg cause of which handshake is not even initiated. Can you please let us know what can cause such an issue and remedy the same? Regards, Prakash

Looking for suggestions about make Mbed TLS APIs non-secure callable APIs on armv8m

by Lee, William

Hi Mbed TLS, I am looking for some suggestions about make some (or all) Mbed TLS APIs non-secure callable APIs on armv8m. The background is that I am going to have a secure firmware that provides encryption services by building part (or whole) of Mbed TLS into that firmware and make those original mbedtls_x APIs non-secure callable, so the existing non-secure firmware could link those non-secure callable APIs and use them. Some of my thoughts: (1) The easiest way to do it I can think of is just add the attribute "cmse_nonsecure_call" to those APIs' declaration (or use a macro to wrap the attribute for conditional build to not impact others don't want it), but I do not think this modification could be accepted by upstream 🙂. (2) So my another thought is duplicate all header files and put them under another folder, assuming it is my-include folder, then I can do whatever I want to my-include folder, but there is also a problem I can think of: a merge/compare burden between include and my-include folder after I have updated Mbed TLS. I really appreciate other suggestions! Thanks, William

Setting ciphersuite causes MBEDTLS_ERR_SSL_ILLEGAL_PARAMETER

by Mbed TLS

My mbedtls client has been working for 2 years. It did what I required and has been stable. However, I now need to force a new server to use my preferred cipher suite. I found the helper function to force the cipher suite here: https://github.com/Mbed-TLS/mbedtls/blob/de4d5b78558666d2e258d95e6c5875f9c7… I added mbedtls_ssl_conf_preference_order(conf, MBEDTLS_SSL_SRV_CIPHERSUITE_ORDER_CLIENT) to the end of the function to force the server to choose my ciphersuite. Prior to this change I called the mbedtls functions in this chronological order: mbedtls_ssl_init(&_ssl); mbedtls_ssl_config_init(&_conf); mbedtls_ctr_drbg_init(&_ctr_drbg); mbedtls_entropy_init(&_entropy); mbedtls_x509_crt_init(&_cacert); mbedtls_pk_init(&_pkey); mbedtls_ctr_drbg_seed mbedtls_ssl_config_defaults mbedtls_ssl_conf_rng mbedtls_ssl_conf_authmode mbedtls_x509_crt_parse_file mbedtls_ssl_conf_ca_chain mbedtls_ssl_setup mbedtls_ssl_set_hostname and then proceed to call: mbedtls_ssl_set_bio mbedtls_ssl_handshake Now: If I call mbedtls_ssl_conf_ciphersuites BEFORE mbedtls_ssl_config_defaults, the ciphersuite list is ignored/seems to get overriden. If I call mbedtls_ssl_conf_ciphersuites AFTER mbedtls_ssl_config_defaults, my ciphersuite list changes are accepted and transmitted (I can see in Wireshark). The server then responds agreeing to use my chosen cipher suite. However, mbedtls_ssl_handshake returns with value -26112, which I have looked up to be MBEDTLS_ERR_SSL_ILLEGAL_PARAMETER. Unfortunately I have no clue what is causing this. Could somebody please advise how this should be done? I can see Client2 example but there are functions I have which are not in there. Client1 seems too simple for me but Client2 seems beyond what I require.

Connect using IP address instead of URL "509 - Certificate verification failed, e.g. CRL, CA or signature check failed"

by M M

I am using MbedTLS client code based on this: https://github.com/machinezone/IXWebSocket/blob/master/ixwebsocket/IXSocket… I am connecting to a server via it's URL. However, I would like to connect directly using an IP address returned from running the traceroute command on the URL. So I replaced the URL with the IP address. However, MBedTLS fails on the handshake: https://github.com/machinezone/IXWebSocket/blob/master/ixwebsocket/IXSocket… I get the error: "error in handshake : X509 - Certificate verification failed, e.g. CRL, CA or signature check failed" If I revert back to URL, it works. The IP address does exist. How can I connect using the IP address, instead of the URL?

Mbed TLS 4.0 roadmap and bignum/ecp API

by Gernot Kvas

Hi all, From the announcement and also the long term plans (https://mbed-tls.readthedocs.io/en/latest/project/long-term-plans/) it is apparent that bignum/ecp operations on the public API will go away and usage will be restricted to internal only. I do understand and welcome the shift towards PSA API and to abandon the ALT interface for higher level legacy API crypto functions. However, I'm not so positive about removal of the bignum and ecp API. There are projects using those functions even in their PSA porting layer (Matter comes to mind: https://github.com/project-chip/connectedhomeip/blob/master/src/crypto/CHIP…) or projects using the bignum layer as abstraction (Zephyr hostap/wpa_supplicant: https://github.com/zephyrproject-rtos/hostap/tree/main/src/crypto, crypto_mbedtls*.c). There might be a case to support those functions to have (hardware-accelerated) low level building blocks for algorithms Mbed TLS doesn't yet or never will support. As other SSL libraries such as OpenSSL also expose similar API (BN_ and EC_POINT_ ), the removal in Mbed TLS will certainly leave a gap. What's the view here from the project team? Cheers, Gernot

Major changes in Mbed TLS 4.0

by Gilles Peskine

Hello, Following consultations with the community and internal discussions among the Mbed TLS maintenance team, we can now present the major changes that will happen in the next major version of Mbed TLS. Our plan remains to release in the second quarter of 2025. The next major version will focus on two things: 1. The cryptography library will be a separate product called TF-PSA-Crypto 1.0. The X.509 and TLS library will be called Mbed TLS 4.0, and will rely on TF-PSA-Crypto for all cryptographic functionality. 2. This release completes the migration of cryptography APIs from classic mbedtls APIs to PSA APIs. Please find more information below about what this means in practice. What follows are just headlines, not an exhaustive list of changes. We expect many small changes that do not affect major functionality. Please note that the changes presented here are our current plan. We may revise it based on new inputs, new insights or unexpected hurdles. You can follow the advancement of the design, planning and development of the next release on the 4.0+1.0 planning board at https://github.com/orgs/Mbed-TLS/projects/15/views/1 . Removal of legacy APIs The following low-level application interfaces will no longer be present in the API of TF-PSA-Crypto 1.0 and Mbed TLS 4.0: * Hashes: hkdf.h, md5.h, ripemd160.h, sha1.h, sha3.h, sha256.h, sha512.h; * Random generation: ctr_drbg.h, hmac_drbg.h, entropy.h; * Ciphers and modes: aes.h, aria.h, camellia.h, chacha20.h, chachapoly.h, cipher.h, cmac.h, gcm.h, poly1305.h; * Private key encryption mechanisms: pkcs5.h, pkcs12.h. * Asymmetric cryptography: bignum.h, dhm.h, ecdh.h, ecdsa.h, ecjpake.h, ecp.h, rsa.h. The cryptographic mechanisms remain present, but they will only be accessible via the PSA API (psa_xxx functions introduced gradually starting with Mbed TLS 2.17). If you maintain code that uses these interfaces, you can already start migrating it today, since almost all PSA interfaces are available in the mbedtls-3.6 long-time support branch (and many even in 2.28 LTS). Please consult the PSA transition guide https://github.com/Mbed-TLS/mbedtls/blob/mbedtls-3.6/docs/psa-transition.md for guidance. Some non-PSA crypto interfaces will still be present in TF-PSA-Crypto 1.0: * pk.h will remain with some changes, mainly to provide an interface to key parsing and formatting which does not have a PSA equivalent yet. * md.h will remain as a thin layer over PSA hash functions (not HMAC) to ease the transition. * nist_kw.h will remain because it does not have a PSA equivalent yet. Removal of legacy integration interfaces TF-PSA-Crypto 1.0 and Mbed TLS 4.0 will no longer support MBEDTLS_xxx_ALT replacement of functions and modules. Use PSA transparent drivers instead. TF-PSA-Crypto 1.0 and Mbed TLS 4.0 will no longer support MBEDTLS_PK_RSA_ALT and MBEDTLS_PSA_CRYPTO_SE_C. Use PSA opaque drivers instead. TF-PSA-Crypto 1.0 and Mbed TLS 4.0 will no longer have the mbedtls/entropy.h interface to configure entropy sources. This will be replaced by PSA random drivers. In addition, we are planning to rework the platform abstraction layer (MBEDTLS_PLATFORM_xxx configuration options). More details will be available in the coming months. Removal of legacy mechanisms The following cryptographic mechanisms are planned to be removed in TF-PSA-Crypto 1.0 and Mbed TLS 4.0: * DES (including 3DES). * PKCS#1v1.5 encryption/decryption (RSAES-PKCS1-v1_5). (OAEP, PSS, and PKCS#1v1.5 signature are staying.) * Finite-field Diffie-Hellman with custom groups. (RFC 7919 groups remain supported.) * Elliptic curves of size 225 bits or less. The following cipher suites are planned to be removed from (D)TLS 1.2 in Mbed TLS 4.0: * TLS_RSA_* (including TLS_RSA_PSK_*), i.e. cipher suites using RSA decryption. (RSA signatures, i.e. TLS_ECDHE_RSA_*, are staying.) * TLS_ECDH_*, i.e. cipher suites using static ECDH. (Ephemeral ECDH, i.e. TLS_ECDHE_*, is staying.) * TLS_DHE_*, i.e. cipher suites using finite-field Diffie-Hellman. (Ephemeral ECDH, i.e. TLS_ECDHE_*, is staying.) * TLS_*CBC*, i.e. all cipher suites using CBC. Non-functional changes Due to the separation into two separate products (TF-PSA-Crypto and Mbed TLS), there will be major changes to the directory structure and to the build system. We plan to use CMake as the primary build system. Since TF-PSA-Crypto is a new product, identifiers that are not PSA interfaces (such as optimisation options and platform interfaces) will be renamed with a new prefix. Best regards, -- Gilles Peskine Mbed TLS developer

Usage of ECB in AES mode

by Chaitanya Tata

Hi, ECB is unsecure, see https://en.wikipedia.org/wiki/Block_cipher_mode_of_operation#Electronic_cod… and shouldn't be used in production. So, I have switched to one of CBC/CMAC/CTR modes, but in `mbedtls_cipher_cmac_starts` I see that it only accepts ECB variants, and also doesn't seem to be using the `type`. From https://github.com/Mbed-TLS/mbedtls/issues/8617 I see that ECB for AES was intentional, even for the CMAC API. Is this expected? 1. Is using ECB for CMAC API correct? 2.Shouldn't we remove the ECB altogether? Appreciate any clarifications. Cheers, Chaitanya.

TLS 1.3 failures in Mbed TLS 3.6.0

by Gilles Peskine

Hello, Mbed TLS 3.6.0 was the first release to enable TLS 1.3 support by default. Unfortunately, this breaks many applications that open a TLS connection with default settings, which are now negotiating TLS 1.3 instead of TLS 1.2, but hit a difference in how Mbed TLS 3.6.0 implements the two versions of the protocol. The most common symptom is: you are using the default configuration (or something close), and your application fails in the handshake with an internal error whenever it negotiates TLS 1.3. To resolve this, call psa_crypto_init() before starting a TLS handshake. For a list of other known issues, please see https://github.com/Mbed-TLS/mbedtls/issues/9223 If you are encountering a problem due to the enablement of TLS 1.3 that is not listed on that page, please let us know by opening an issue on GitHub. If no workaround or patch is available for your problem yet, you can disable TLS 1.3 by calling mbedtls_ssl_conf_max_tls_version(ssl_config, MBEDTLS_SSL_VERSION_TLS1_2) before mbedtls_ssl_setup(). We are planning to fix all the issues listed on that page before the 3.6.1 patch release. We do not yet have a date for the 3.6.1 release. Best regards, -- Gilles Peskine Mbed TLS developer

TLS-Exporter in TLS 1.3

by Maximilian Fillinger

Hello! I am trying to add TLS 1.3 support to OpenVPN when using Mbed TLS as the TLS library. My current roadblock is that OpenVPN needs the TLS-Exporter functionality (RFC 8446, Section 7.5). For TLS 1.2, we get the master secret through mbedtls_ssl_set_export_keys_cb() and then implement the exporter using mbedtls_ssl_tls_prf(). For TLS 1.3, an approach like this doesn't work because the callback isn't called with the exporter master secret. Am I missing anything, or does this feature not yet exist? Are there any plans to add it? If not, I'd be interested in trying to make a patch. Best regards, Max

bestwritercontent

by hma3yf39＠mediaholy.com

https://www.bestwritercontent.com A man was going to the house of some rich person. As he went along the road, he saw a box of good apples at the side of the road. He said, "I do not want to eat those apples; for the rich man will give me much food; he will give me very nice food to eat." Then he took the apples and threw them away into the dust. He went on and came to a river. The river had become very big; so he could not go over it. He waited for some time; then he said, "I cannot go to the rich man's house today, for I cannot get over the river." He began to go home. He had eaten no food that day. He began to want food. He came to the apples, and he was glad to take them out of the dust and eat them.

[Mbed-tls-announce] Requests for feedback about Mbed TLS 4: summary

by Gilles Peskine via Mbed-tls-announce

Hello, In the past few weeks, we have sent a number of requests for feedback on the mbed-tls mailing list about the next major release of Mbed TLS (TF-PSA-Crypto 1.0 + Mbed TLS 4.0). Most are about features that we may remove because we think they are not used much and are not worth maintaining. This message is a summary of the requests. If you have concerns about any of these topics, please reply on the GitHub issue (preferred), or on the mbed-tls mailing list, or by private email. (If you reply privately, we will anonymize before sharing outside Arm.) Please reply before 31 July so that we have time to plan 4.0 preparation.

Can TLS client send `Encrypted Alert 21` to server

by Satya Prakash Prasad

Hi All, We are using the MBedTLS 3.6.0 release stack and often see the TLS client -> server sending Encrypted Alert 21 packets followed by closing the SSL connection (or rather reconnection starting from new handshake messages). As far as I understand Alert 21 is a fatal message stating Decryption of a TLSCiphertext record is decrypted in an invalid way: either it was not an even multiple of the block length or its padding values, when checked, were not correct - copied from the Internet. But then Handshake and Application Data goes thru fine for a while and then we see our client sending Alert 21 encrypted message Is it legitimate that the client can send Alert 21 messages to the server and close the current connection - we are observing that the server application is waiting for messages from the client and is un-aware that a connection reset has occurred. So the server application states a timeout for receiving messages from the client. Further, how can we assert such a scenario? When and how can it occur? Is there a way we can simulate it and send details to owners of server firmware to fix their issue? Regards, Prakash

3.6.0 library size

by Steven Burck

On a project at my company, we're using mbedtls to encrypt and sign our data. We began the project with mbedtls 2.2.6, and have continuously upgraded until now, 3.6.0. I've noticed my application has grown greatly since then, even though we are only using the following APIs: Encryption:(only decryption on the embedded side) - mbedtls_aes_init - mbedtls_aes_setkey_dec - mbedtls_aes_crypt_cbc Signing (only verification on the embedded side) - mbedtls_ecp_point_read_binary - mbedtls_sha256_init/free - mbedtls_sha256_starts_ret - mbedtls_sha256_update_ret - mbedtls_sha256_finish_ret - mbedtls_ecdsa_init/free - mbedtls_ecp_group_load - mbedtls_ecdsa_read_signature The size of libembedcrypto.a has grown from under 400K to almost 800K. I've tried reducing it with mbedtls_config,h, but it is not entirely clear to me which #defines do what. I tried one of the sample configs which by it;s name looked promising (crypto-config-ccm-aes-sha256.h), and it reduced the size of the library by 90%, but left me with link errors for all of the above functions. Going one #define at a time manually to see if it saves or grows is slow, and so I hoped I could find some assistance here. Thanks in advance

Question about random number g

by Zhang, Hao

Hi TF-M and mbedtls community, I am new to TF-M, I have a few questions about CryptoCell and random number generation. Thank you in advance. 1. I figure there seems to have two CryptoCell 312 implementations within TF-M. One under lib/ext/cryptocell-312-runtime and the other under platform/ext/accelerator/cc312/cc312-rom. What are the difference between these two? 2. For lib/ext/cryptocell-312-runtime, it does not define MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG whereas /ext/accelerator/cc312/cc312-rom does. Does that mean cryptocell-312-runtime is initiating RNG cryptodriver by using mbedtls_entropy_add_source whereas cc312-rom is using mbedtls_psa_external_get_random<https://github.com/zephyrproject-rtos/trusted-firmware-m/blob/8df9cc8baf462…>. If so, may I ask why these two cryptocells take two different approaches? I read from one of the documentation that mbedtls_psa_external_get_random is used when entropy is sufficient. So if entropy is sufficient, is it always preferred to have MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG defined and implements mbedtls_psa_external_get_random? What are the differences between the two approaches. 3. I also found cryptocell-312-runtime defines the entry point function cc3xx_init_random<https://github.com/zephyrproject-rtos/trusted-firmware-m/blob/8df9cc8baf462…>. But since PSA random number entry point funciton is not complete, the cc3xx_init_random is not being called anywhere, right? [https://opengraph.githubassets.com/17cdebc400b0ed807c620b586b21f3f77ff9c5d3…]<https://github.com/zephyrproject-rtos/trusted-firmware-m/blob/8df9cc8baf462…> trusted-firmware-m/platform/ext/accelerator/cc312/cc312-rom/psa_driver_api/src/cc3xx_psa_random.c at 8df9cc8baf46252fd188bba1d87333a8daa9a5e8 · zephyrproject-rtos/trusted-firmware-m<https://github.com/zephyrproject-rtos/trusted-firmware-m/blob/8df9cc8baf462…> Zephyr repository tracking https://git.trustedfirmware.org/trusted-firmware-m.git/ - zephyrproject-rtos/trusted-firmware-m github.com 4. I know random number generation PSA entry point function is in development, may I ask when that would be expected to complete? Thank you very much! Best regards, Hao

Request for feedback about Mbed TLS 4: DRBG interfaces

by Gilles Peskine

Hello, This is a request for feedback about the next major release of Mbed TLS (TF-PSA-Crypto 1.0 + Mbed TLS 4.0). (Mbed TLS 3.6 LTS will remain supported with its current feature set until at least Q2 2027.) Please reply to this thread or on the GitHub issue linked below. If you wish to leave feedback privately, you can reply privately and your feedback will be anonymized before sharing outside Arm. https://github.com/Mbed-TLS/TF-PSA-Crypto/issues/107 Should TF-PSA-Crypto 1.0 (and thus Mbed TLS 4.0) have an interface for *pseudo*-random generation? It will, of course, still have a pseudorandom generator (= deterministic random bit generator = DRBG) internally, to power psa_generate_random(), psa_generate_key(), etc. The question is whether there will still be a public interface to create other DRBG instances, and if so, with what interface. If you want to be able to create instances of HMAC_DRBG and CTR_DRBG from application code in TF-PSA-Crypto 1.0, please let us know what your use case is. In particular, what parameters do you need (HMAC_DRBG and CTR_DRBG have many)? Do you need reseeding, and if so under whose control (the DRBG, or the caller)? In the absence of feedback, it is likely that HMAC_DRBG and CTR_DRBG will not be publicly available. Best regards, -- Gilles Peskine Mbed TLS developer

mbedtls 3.6.0: zero-sized array gives compiler warning (is undefined behavior)

by Almut Herzog

Hi all, I have a custom configuration where MBEDTLS_ECDSA_C is defined but MBEDTLS_PSA_CRYPTO_C and MBEDTLS_PSA_CRYPTO_CONFIG are not. This leads to a compiler warning in e.g. psa_util.c because a zero-sized array is declared (because PSA_VENDOR_ECC_MAX_CURVE_BITS is defined as 0). As of C99, §6.7.5.2 Array declarators: "If the expression is a constant expression, it shall have a value greater than zero." psa_util.c: #if defined(MBEDTLS_PSA_UTIL_HAVE_ECDSA) // Line 368 int mbedtls_ecdsa_raw_to_der(...) // Line 433 unsigned char r[PSA_BITS_TO_BYTES(PSA_VENDOR_ECC_MAX_CURVE_BITS)]; // Line 436 --> becomes in my config: unsigned char r[0]; MBEDTLS_PSA_UTIL_HAVE_ECDSA is automatically defined in my configuration due to the following code in config_adjust_legacy_crypto.h: #if defined(MBEDTLS_ECDSA_C) || (defined(MBEDTLS_PSA_CRYPTO_C) && \ (defined(PSA_WANT_ALG_ECDSA) || defined(PSA_WANT_ALG_DETERMINISTIC_ECDSA))) #define MBEDTLS_PSA_UTIL_HAVE_ECDSA #endif PSA_VENDOR_ECC_MAX_CURVE_BITS only receives a non-zero value if a PSA_WANT_<CURVE>, e.g. PSA_WANT_ECC_BRAINPOOL_P_R1_256, is defined. PSA_WANT_<CURVE> only gets defined in crypto_config.h if MBEDTLS_PSA_CRYPTO_CONFIG is defined (which it is not in my configuration). I have worked around it by explicitly defining e.g. PSA_WANT_ECC_BRAINPOOL_P_R1_256 in my configuration. But I believe there is some mismatch in the defines, at least in this example case, because mbedtls_ecdsa_raw_to_der() is only used in pk_wrap.c if MBEDTLS_USE_PSA_CRYPTO is defined. Impact: * In general, zero-sized arrays have undefined behavior in C (but are allowed by some compiler extensions) and thus behave differently for different compilers --> you might want to review PSA_VENDOR_ECC_MAX_CURVE_BITS and PSA_VENDOR_FFDH_MAX_KEY_BITS (and possibly more definitions) that fall through to 0 and are used as array sizes. * In my particular case, I believe code is compiled that is not needed (defines in psa_util.c and pk_wrap.c do not seem to match)

Request for feedback about Mbed TLS 4: size_t printing with %zu

by Gilles Peskine

Hello, This is a request for feedback about the next major release of Mbed TLS (Mbed TLS 4.0). (Mbed TLS 3.6 LTS will remain supported with its current feature set until at least Q2 2027.) Please reply to this thread or on the GitHub issue linked below. If you wish to leave feedback privately, you can reply privately and your feedback will be anonymized before sharing outside Arm. https://github.com/Mbed-TLS/mbedtls/issues/9307 Mbed TLS requires a C99 platform, with some pragmatic restrictions. One restriction is that we do not require printf and friends to support %zu for size_t printing. Starting with Mbed TLS 4.0, we are considering requiring printf() and friends (or the mbedtls_printf() and friends alternatives if overridden) to support %zu. This only affects the TLS library, not X.509 and crypto. Is it still necessary in 2025 to support platforms where printf() does not support the z modifier?

Request for feedback about Mbed TLS 4 and TF-PSA-Crypto: build system

by Gilles Peskine

Hello, This is a request for feedback about the next major release of Mbed TLS (TF-PSA-Crypto 1.0 + Mbed TLS 4.0). (Mbed TLS 3.6 LTS will remain supported with its current feature set until at least Q2 2027.) Please reply to this thread or on the GitHub issue linked below. If you wish to leave feedback privately, you can reply privately and your feedback will be anonymized before sharing outside Arm. https://github.com/Mbed-TLS/TF-PSA-Crypto/issues/106 We are evaluating build systems for TF-PSA-Crypto, and this will influence the Mbed TLS build as well (the Mbed TLS build scripts will call the TF-PSA-Crypto build scripts, whatever they are). Our current thinking is that we would like to have *CMake as the sole build system*. (We're still investigating whether CMake can do all we need.) That would mean that we would no longer provide GNU makefiles or Visual Studio solutions. As this remains a C project, for just building the library, compiling all the .c files with an include path covering all the .h files will keep working in common cases (but, as today, it isn't something we support officially). The main case I can think of where this wouldn't work is when cryptographic accelerator support requires special includes or compiler flags. Are there environments where the use of CMake is a problem? What is the oldest version of CMake that you'd like us to be compatible with? Best regards, -- Gilles Peskine Mbed TLS developer

Request for feedback about Mbed TLS 4: RSA decryption cipher suites

by Gilles Peskine

Hello, This is a request for feedback about the next major release of Mbed TLS (Mbed TLS 4.0). (Mbed TLS 3.6 LTS will remain supported with its current feature set until at least Q2 2027.) Please reply to this thread or on the GitHub issue linked below. If you wish to leave feedback privately, you can reply privately and your feedback will be anonymized before sharing outside Arm. https://github.com/Mbed-TLS/mbedtls/issues/8170 We are considering removing support for RSA and RSA-PSK key exchanges in Mbed TLS 4. These are cipher suites that use RSA encryption, as opposed to cipher suites using a key agreement (ECDHE) plus RSA signature. These key exchanges are hard to implement securely (we believe we got it right, but it's very delicate code), and they add significantly to the complexity of the TLS code. They have been formally deprecated for a long time and were removed in TLS 1.3. However, I'm aware that some ecosystems are clinging to RSA key exchange. Are RSA-encryption key exchanges still relevant for Mbed TLS? If you want Mbed TLS 4 to keep supporting RSA-encryption cipher suites in TLS 1.2, please let us know and tell us about your use cases.

Request for feedback about Mbed TLS 4: AESNI without compiler intrinsics

Hello, This is a request for feedback about the next major release of Mbed TLS (TF-PSA-Crypto 1.0 + Mbed TLS 4.0). (Mbed TLS 3.6 LTS will remain supported with its current feature set until at least Q2 2027.) Please reply to this thread or on the GitHub issue linked below.

The assembly code works with GCC and Clang without any compilation options, but not with MSVC. The intrinsics work with MSVC, but not with ancient GCC/Clang and they require compiling at least aesni.c with suitable CPU variant options (e.g. -maes -mpclmul for Clang). We're considering removing the assembly implementation. Is there still interest in compiling AESNI support with older compilers or with simple build systems that don't pass machine options?

How to read ecp private key

Re: PSA Cryptoprocessor Driver Interface

by Shebu Varghese Kuriakose

+ Mbed TLS mailing list as well for visibility and any comments. Regards, Shebu From: Zhang, Hao via TF-M <tf-m(a)lists.trustedfirmware.org> Sent: Wednesday, June 5, 2024 12:37 AM To: tf-m(a)lists.trustedfirmware.org Subject: [TF-M] PSA Cryptoprocessor Driver Interface Hi TF-M community, TF-M allows Semiconductor vendors to plug in their HW accelerator using PSA cryptoprocessor driver interface. I have a couple of questions in terms of the driver interface. 1. To port customized HW accelerator to TF-M's Crypto service for TF-M v2.1.0 LTS using driver interface, for the multipart operation, https://github.com/zephyrproject-rtos/mbedtls/blob/zephyr/docs/proposed/psa… states that "A driver that implements a multi-part operation must define all of the entry points in this family as well as a type that represents the operation context." Take aead encrypt as an example, if the underlying hardware does not support aead_abort, could it implements aead_abort by simply return PSA_ERROR_NOT_SUPPORTED? 1. The driver interface depends heavily on psa_crypto_driver_wrappers.h to dispatch operations to customized HW accelerator, where the psa_crypto_driver_wrappers.h file is automatically generated by scripts/data_files/driver_templates/psa_crypto_driver_wrappers.h.jinja. To port customized HW accelerator to TF-M's Crypto service for TF-M v2.1.0 LTS, would the approach be creating a customized psa_crypto_driver_wrappers.h.jinja file, the driver description file in JSON, and entry point functions. If so and we are considering upstreaming TF-M in the future, all these files would go inside platform/ext/accelerator/<vendor name>. Efforts need to be made so files such as psa_crypto_driver_wrappers.h.jinja should point to mbedtls, right? Additionally, as .jinja is retiring (mentioned in another email exchange), how would semi vendors update psa_crypto_driver_wrappers.h in the future?

mbedtls_x509_dn_gets(): Different DN string for 2.28.8 and 3.6.0

by Almut Herzog

Hi, Not sure whether I should report this as a bug or maybe an enhancement issue or maybe it is as-designed: I recently migrated from 2.28.8 to 3.6.0 and noticed: An X.509 certificate DN coded as T61 string (done automatically so by openssl for a DN that contains an underscore) is returned as a hex string in 3.6.0 while it is returned as a regular, human-readable string in 2.28.8. As this is not working for us I patched mbedtls_c509_dn_gets() locally as shown below. Please feedback whether you want me to report an issue or if the 3.6.0 behavior is as-designed for a good reason.

What is the right way to use ecp

by arun.lal＠intel.com

I have a very basic use case, to use a buffer and perform ECDSA encryption in a TA application. I also want to read back the private key which is generated. I see functions like mbedtls_ecp_gen_key but I have failed to find enough details on what steps to follow to use this function. It will be really helpful if I can be pointed to a example. Or let me know If there is some other way to achieve the end goal.

Are you requesting feedback about ED25519?

by Christian Huitema

Hello Gilles, I see that you are requesting feedback on a set of issues, but not on support of EdDSA. Yet, support for ED25519 is an important requirement for TLS and QUIC. With other crypto suites, the CPU load is significantly lower for ED25519 than for ECDSA/secp255r1. Somewhat related, but there is also demand for ChaCha20-poly1035, for performance reason on some systems. Are there any plans? -- Christian Huitema

Request for feedback about Mbed TLS 4: CBC cipher suites

by Gilles Peskine

Hello, This is a request for feedback about the next major release of Mbed TLS (Mbed TLS 4.0). (Mbed TLS 3.6 LTS will remain supported with its current feature set until at least Q2 2027.) Please reply to this thread or on the GitHub issue linked below. If you wish to leave feedback privately, you can reply privately and your feedback will be anonymized before sharing outside Arm. https://github.com/Mbed-TLS/mbedtls/issues/9202 In 2025 (by the time Mbed TLS 4.0 is released), are CBC-based cipher suites still relevant for Mbed TLS? If you still need support for CBC-based cipher suites (as opposed to cipher suites using AEAD: CCM, GCM or ChaChaPoly, or null cipher suites), please let us know. Removing them would allow us to significantly simplify some parts of the TLS code. They are difficult to implement securely due to being very sensitive to side channels; we think we got it right, but at the expense of performance, code size and maintainability. One option we're considering is to keep CBC cipher suites, but only when the encrypt-then-MAC (EtM) extension is enabled. However, this is problematic because the TLS protocol does not allow a client to indicate that it requires EtM support, which could lead to a failed connection even when the server also have an AEAD cipher suite in common.

However, there is one main exception: the ECC code allows replacing just code ECC arithmetic (MBEDTLS_ECP_ALT) or even just selected functions (sub-options of MBEDTLS_ECP_INTERNAL_ALT). On the other hand, the granularity of PSA accelerators is whole mechanisms: ECDH, ECDSA, etc. on a specific set of curves. If you are currently using MBEDTLS_ECP_ALT or MBEDTLS_ECP_INTERNAL_ALT to implement accelerated ECC airthmetic and relying on code from ecp.c, ecdh.c and ecdsa.c to provide ECC mechanisms, please let us know what your requirements are and how much of a pain it would be to have to fully implement ECDH/ECDSA/... in your driver.

Certificate validation

by Sushma Narayan Shetty

Hi Team, Need support on one the below query. I had previously raised this in issue #9116 : Client certificate verify · Issue #9116 · Mbed-TLS/mbedtls · GitHub<https://github.com/Mbed-TLS/mbedtls/issues/9116> .However I was asked to redirect the query to the mbedTLS support. Q#1 : I have a client certificate chain (end entity cert, intermediate cert and root cert) and I have got 1 public key (extracted from root CA cert) on my server. Is there any way in mbedTLS where I can validate the client certificate using just the public key of the root CA and not the whole root CA certificate on my server? As per my understanding of CA and certificate validation we would need a whole CA cert and not just the public key of the root certificate. However, I would like to know if there are any API's in mbedTLS for this validation?

Testing an an Ubuntu VM, issue with configuration

by Christian Huitema

I am testing a test program in an Ubuntu VM, and I have an issue. I started by configuring MbedTLS in "full" mode (scripts/config.py full), but in that case the linker fails, "in function `psa_load_builtin_key_into_slot`, psa_crypto_slot_management.c: undefined reference to 'mbedtls_psa_platform_get_builtin_key`. I can suppress the error by editing `include\mbedtls\mbedtls_config.h` and removing the option `MBEDTLS_PSA_CRYPTO_BUILTIN_KEYS`. The compile succeeds, but the call to `psa_crypto_init` fails when initializing the RNG module. I am struggling. I must be making some mistake, I will keep trying to understand, but I would appreciate a little bit of help! -- Christian Huitema

Using the "psa_verify_message" function

by Christian Huitema

The specification of the "psa_verify_message" function is simple enough: pass a key ID, an algorithm ID, the data that were signed, the signature received from the peer, and receive a status. There is just one tiny problem: in the application, the algorithm ID is specified as a 16 bit TLS SignatureScheme (https://www.iana.org/assignments/tls-parameters/tls-parameters.xhtml#tls-si…), which is not quite the same as "psa_algorithm_t". Is there a simple way to covert from TLS SignatureScheme to PSA ALgorithm identifier? Maybe a two columns table? -- Christian Huitema

Error while parsing certificate

by Subramanian Gopi Krishnan

Hi, I have an inhouse developed secure authentication program that uses certificate for authentication. I have used mbedtls library for the x.509 certificate verification purpose. In our custom PKI we have only three level of certificates, Root-CA -> Intermediate-CA -> Device-Cert. The embedded device has very limited memory, so instead of sending whole certificate chain, the devices communicates intermediate_CA and device cert (in der format base64 encoded) in separate packet. Root-CA will be available on node as trusted-ca. Intermediate is verified against Root; then device cert is verified against intermediate. The problem is, the poc developed on linux platform is working fine - but on embedded platform I encounter either 0x3b00(parsing failed) or 0x2700(with flag 8). Also the error code are inconsistent. I verified the integrity of packet with certificate using crc16. So no chance of certificate getting corrupted. Also verified the certificate's base64 format integrity using crc16. All certificates are sha256WithRSAEncryption; RSA Public-Key: (4096 bit) Attached config.h on target platform for reference - could you help me if anything wrong with configuration. While trying to trace, the flag was set from x509_crt.c from below code. /* No parent? We're done here */ if( parent == NULL ) { printf("NO_PARENT\r\n"); *flags |= MBEDTLS_X509_BADCERT_NOT_TRUSTED; return( 0 ); } Any clue would be helpful. Thanks, Gopi Krishnan

Help debugging TLS handshake failure

by Jay Malhotra

Hi, I'm having an issue with some code using Mbed TLS and I was pointed to this mailing list as the correct place to ask for support. Please let me know if I should ask somewhere else. I'm trying to connect to my local government's website via a Raspberry Pi Pico, using a TLS client based on lwIP and altcp_tls. It's based off of the example from the Raspberry Pi team here: https://github.com/raspberrypi/pico-examples/tree/master/pico_w/wifi/tls_cl… . My Mbed TLS config is the same as what they have there, aside from some extra defines I added for debugging. The issue I am facing is that while various hosts work fine (e.g. postman-echo.com for testing), when I attempt to connect to my local council's website I get a TLS handshake error. My client has TLS verification disabled for the moment, but I have tried with the correct root certificates as well. The error I receive is mbedtls_ssl_handshake failed: -30592 I cloned down the mbed_tls repo, and had a similar issue with ssl_client1 -- i.e. works on postman-echo, not for my government, with mbedtls_ssl_handshake returning the error. Notably however, the error code in that instance was -31488. Interestingly, ssl_client2 works flawlessly with both hosts. I wasn't quite sure what part of ssl_client2 would cause it to work with my government host, as it's several thousand lines long, but I'm sure the answer is in there somewhere. I've attached a trace taken with debug logging level 4 on my Pico which shows where the TLS handshake is failing. I'd really appreciate any guidance of areas to troubleshoot next. Thanks, Jay

Memory Cleanup of Persistent Key Slots

by Zak, Kevin

Hello, I am referencing the Mbed TLS (v3.5) implementation for key slots & how they interact with the PSA key management APIs. In the PSA documentation<https://arm-software.github.io/psa-api/crypto/1.1/overview/implementation.h…>, sections 6.3.3 and 6.3.4 describe that persistent keys (that are handled according to the Memory cleanup rule) would have to be loaded from NVM on each use of the key, unless PSA_KEY_USAGE_CACHE is set. However, I'm not certain I see this followed in the Mbed TLS code. 'psa_export_key()' is the simplest example. This function retrieves and locks the key slot for the requested key ID using 'psa_get_and_lock_key_slot_with_policy()' - this function may retrieve the persistent key material from NVM if necessary (it seems to return sooner if it finds that persistent key in a slot already). The remainder of psa_export_key() copies the key material from the slot directly to the output buffer, but it never removes the key material from the slot. My understanding was that the key material should be removed from the slot unless PSA_KEY_USAGE_CACHE was set. Can anyone clear this up for me? Does this just mean that the reference implementation does not follow the memory cleanup rule, or is the slot buffer cleared at some later point for the persistent key? Thank you, Kevin Zak

The road towards Mbed TLS 4.0

by Nathan Sircombe

Dear Mbed TLS users, We recently announced the release of Mbed TLS 3.6.0, starting the 3.6 long-term support branch. We intend for this to be the last 3.x feature release. Mbed TLS 3.6.x will as usual receive bug fixes (including security improvements), but no new features. This will allow the Mbed TLS team to focus on preparing the next major release, Mbed TLS 4.0, planned for 2025 (expect further updates when the timeline becomes more precise). The main focus of Mbed TLS 4.0 is to complete the migration to PSA crypto APIs. This means that most mbedtls_xxx cryptography APIs will be removed. We expect mbedtls_x509 and mbedtls_ssl to change in relatively minor, but sometimes incompatible ways. Alongside this technical change, the crypto APIs will be published as a separate product, TF-PSA-Crypto<https://github.com/Mbed-TLS/TF-PSA-Crypto> (very early preview so far), while the X.509 and TLS libraries will continue to be called Mbed TLS. The work on 4.0 will happen on the development branch in the mbedtls repository, so you can expect more instability than usual on that branch. The mbedtls-3.6<https://github.com/Mbed-TLS/mbedtls/tree/mbedtls-3.6> branch is available if you want the latest patches on Mbed TLS 3.6 LTS. As usual, you can see our high-level plans in the roadmap<https://mbed-tls.readthedocs.io/en/latest/project/roadmap/>, and in more detail on GitHub<https://github.com/Mbed-TLS/mbedtls/issues>. Look for issues labeled api-break<https://github.com/Mbed-TLS/mbedtls/issues?q=is%3Aissue+is%3Aopen+label%3Aa…> (note that we haven't filed issues on all topics yet). We will launch some consultations on the mbed-tls mailing list<https://lists.trustedfirmware.org/mailman3/lists/mbed-tls.lists.trustedfirm…> soon, to gather community input on some topics. Many Thanks, Nathan Sircombe (On behalf of the Mbed TLS development team)

Introductions

by Nathan Sircombe

Hi Mbed TLS list, I’d just like to introduce myself to the wider Mbed TLS community. I’ve recently joined the Mbed TLS team as the Engineering Manager for the Arm team. Although I’m new to this project, I’m not new to Arm having worked here for a while on a number of closed and open source library projects. I look forward to working with you, and meeting some of you on our regular community calls. Cheers, Nathan. p.s. my GitHub usid is nSircombe (https://github.com/nSircombe)

Ask about using mbedtls

by blaine

hello： Recently, I am transplanting mbedtls from a 32-bit system to a 64-bit system. The compilation operating system is ubuntu20.4. The screenshot below is the code I use mbedtls(version number: 2.24.0). In the API mbedtls_rsa_gen_key implementation, there is a line of code that is ""MBEDTLS_MPI_CHK( mbedtls_mpi_lset( &ctx ->E, exponent ) );"", the program crashed at the memset in mbedtls_mpi_set during execution. This has not happened on 32-bit platforms before, so I would like to ask whether it has something to do with the platform used or whether I call the API. It’s a question about how to use it, thank you very much

Exports from the shared libraries vs API

by Zaki, Ahmed

Hi, I am trying to identify the API available by looking up exported symbols from the built shared libraries libmbedcrypto.so ,libmbedtls.so and libmbedx509.so. I noticed that many of the exported functions are not documented here https://mbed-tls.readthedocs.io/projects/api/en/development/ . My question really is, are those functions exported through the shared libraries intended to be so ? For example, function mbedtls_mpi_core_add does not seem to be part of the API but it is exported. Is this intentional ? It's not uncommon that functions would be exported but not part of the API, I just wanted to get some clarification if possible regarding the reasons for doing so in the case of MbedTLS. Thanks Ahmed

MbedTLS Test Cases

by Satya Prakash Prasad

Hi, I am sorry but I need to know test case scenarios to verify what is supported in the recent MBedTLS stack - what should be tested. Objective is that we cover MBedTLS code the maximum. Since I am a new learner, I need to build the test cases from scratch. So I thought to first find from stack what TLS ciphers suites / digest it supports, what are the different keysize, and protocols - TLSvX (where x=1,2 or 3). Then build certificates related to the same and verify the data as found. Are there other ways to find different features in the current MBedTLs stack and verify each one of them? Is this approach the right way - do we have known test case scenarios to verify? Any other additional help will aid us out. Thanks in advance. Regards, Prakash

MbedTLS 3.6.0 - Memory or other issue

by Satya Prakash Prasad

Hi, We are using MbedTLS 3.6.0 in an embedded device which has limited memory available. Since we are implementing the same for the first time hence from the logs please confirm if it is coding integration issue (like caught in infinite loop, not correct integration etc) or the flow errors out because of unavailable of memory. In our embedded device we have allocated .5 MB (half MB) of space for TLS thread stack. How much do we actually need - 1 MB or 2 MB. Is there any memory leak issue? Please find the logs below and let me know is there is any issue in integration or memory issue. Thanks in advance.

TLS 1.3: two question about ticket session

by Michał Antoniak

Hello, I am trying to add TLS 1.3 support to a curl project (https://github.com/MAntoniak/curl). As a result, it has two questions. The first refers to the error code MBEDTLS_ERR_SSL_RECEIVED_NEW_SESSION_TICKET. This suggests an error receiving a new session ticket. I couldn't find anything else in the documentation. However, in the ssl_cllient2.c example application (line 2638), this code is used as a message to the application about a new session ticket. This makes me unsure whether it would be correct to continue receiving application data normally. The second question relates to the receipt of tickets. The curl project does not store session tickets, so it uses the MBEDTLS_SSL_SESSION_TICKETS_DISABLED flag. If this is the case, why do we nevertheless receive a new ticket from the server? Thank you for your reply. Michał Antoniak

Appending a cert to mbedtls_x509_crt

by Roman Janota

Hello, I have an implementation in OpenSSL and am trying to recreate it using MbedTLS. One of the differences in these two I have yet to overcome is the following: Is there a way to treat mbedtls_x509_crt simply as a certificate store? Say I have some PEM data, parse it into a temporary mbedtls_x509_crt and then I would like to append this certificate to said mbedtls_x509_crt certificate store. The following is stated in the docs of mbedtls_x509_crt: > struct mbedtls_x509_crt *next Next certificate in the linked list that constitutes the CA chain. NULL indicates the end of the list. Do not modify this field directly. Is there a way to achieve this if it's advised not to modify the field directly? Thank you in advance, Roman.

mbedtls_ecp_gen_key vs mbedtls_ecdsa_genkey

by Tom Work

Hey All, I am trying to generate ECDSA public-private key pair for self-signed certificate, and came across these examples In gen_key.c <https://github.com/Mbed-TLS/mbedtls/blob/bee96566dac936e7fdfa7aa18b6a1f6767…>, "mbedtls_ecp_gen_key()" is used In ecdsa.c <https://github.com/Mbed-TLS/mbedtls/blob/bee96566dac936e7fdfa7aa18b6a1f6767…>, "mbedtls_ecdsa_genkey()" is used. My questions are: - Which function should be used? (It seems mbedtls_ecdsa_genkey() is just a wrapper of mbedtls_ecp_gen_key()?) - If using mbedtls_ecdsa_genkey(), what are the steps to write the public key into PEM format? (My understanding is that I define a mbedtls_pk_context, and convert its address into mbedtls_ecdsa_context *, and pass the pointer into mbedtls_ecdsa_genkey, and then call mbedtls_ecdsa_genkey(), is this correct?) Thanks, Tom

CA Unknown Certificate

Hi, Please note that while using MBedTLS 3.6.0, when we are trying to verify server / client connection using self-signed mutually trusted certificates we are always getting a CA Unknown Certificate error code 46 alert message.

Public key from certificate?

by Christian Huitema

Public key operations like "psa_verify_message" use a "key-id" argument to represent the public key. Is there a simple way to obtain or register that key-id using the "cert->pk" member of a parsed certificate? -- Christian Huitema

Use of auto-generation approach for mbedtls/mbed-crypto driver psa_crypto_driver_wrappers..h file

by Ruchika Gupta

Hi All, Apologies for the long email. I am adding all the 3 projects (TF-M, mbedTLS and Zephyr) to the mail chain because the issues I discuss below are inter-connected and affect all the three projects. From mbedtls 3.5.0 version, the mbedtls project has migrated to auto-generated psa_crypto_driver_wrappers.h file. https://github.com/Mbed-TLS/mbedtls/blob/development/docs/psa-driver-exampl… https://github.com/Mbed-TLS/mbedtls/blob/development/docs/proposed/psa-driv… On TF-M, mbed-crypto, there are 2 patches for the drivers given below which are still hardcoding their changes and not following the above approach. 1. PSA_CRYPTO_DRIVER_TFM_BUILTIN_KEY_LOADER (0001-Add-TF-M-Builtin-Key-Loader-driver-entry-points.patch) 2. PSA_CRYPTO_DRIVER_CC3XX (0005-Hardcode-CC3XX-entry-points.patch) We at NXP, have migrated our psa crypto wrappers to the above approach using auto-generation. We want to maintain same code base for mbedtls for our SDK's, TFM mbed-crypto as well as align mbedTLS fork in Zephyr. We are increasingly finding it difficult to migrate to newer versions of mbedtls because of hardcoding of above drivers. The problem is specially on the Zephyr front, where in the mbedTLS fork in zephyr these patches from tfm are applied by default. I have queries for all the 3 projects listed below : TF-M --> Can you please let us know what are the plans to migrate these 2 drivers in tfm to the auto-generation approach. If these patches can be migrated to make changes in jinja files rather than hardcoding in psa_crypto_driver_wrappers , things would be much easier to integrate. Is somebody already working on it ? Are you open to accept patches for this change ? mbedTLS --> What is the long term strategy from mbedTLS on this auto-generation ? We still have a lot of hard-coding in .jinja file rather than using drivers.json. Would mbedTLS/new PSA crypto repository start accepting patches for psa wrappers from platforms ? Can the patches which TF-M project maintains be merged in the mbedTLS ? Zephyr --> On Zephyr front, what are the plans to align to this auto-generation approach ? Regards, Ruchika

Why is mbedtls 3.x faster than 2.x?

by Work Only

I recently updated an embedded HTTPs web service using mbedtls from 2.22.0 to 3.2.1, and noticed the performance is about 30% better/faster. This is good for sure, but I am curious, what are the changes contributing to this improvement? Thanks!

Generate a self-signed trusted certificate for server / client

by Satya Prakash Prasad

Hi, Referring to https://mbed-tls.readthedocs.io/en/latest/kb/how-to/generate-a-self-signed-… I am trying to create mutual certificates for server / client self signed certificates. As I derive from the web page the following steps need to be followed: Generic gen_key type=rsa rsa_keysize=2048 filename=ca.key format=pem cert_write selfsign=1 issuer_key=ca.key issuer_name=CN=myserver,O=myorganization,C=NL not_before=20130101000000 not_after=20251231235959 is_ca=1 max_pathlen=0 output_file=my_crt.crt Server Side: What steps to do to create the following files where server.crt is server side certificate, sever.key is the server private key and trusted.pem is the CA that it trusts. server.crt, server.key, trusted.pem[trusted.pem==>is it my_crt.crt] Do we need to create new server keys and certificates then do we need to bundle them - I am not sure how and what steps to do? Client Side What steps to do to create the following file where client.crt is client side certificate, client.key is the client private key and trusted.pem is the CA that it trusts. client.crt, client.key, trusted.pem[trusted.pem==>is it my_crt.crt] Do we need to create new client keys and certificates then do we need to bundle them - I am not sure how and what steps to do? Objective: Objective is that client and server should be able to connect securely successfully using their certs Request to provide help related to the generation of self-signed client / server certs that can be used for SSL handshake using MBedTLS library.

Support SM2, SM3, SM4

by Zhi Liu

Hi all, Given TLS 1.3 has added two new cipher suites in RFC 8998 ( https://datatracker.ietf.org/doc/html/rfc8998), it would be useful to add these algorithms and ciphersuites in Mbedtls. CipherSuite TLS_SM4_GCM_SM3 = { 0x00, 0xC6 }; CipherSuite TLS_SM4_CCM_SM3 = { 0x00, 0xC7 }; There are some posts in this topic, https://github.com/Mbed-TLS/mbedtls/pull/4091, https://github.com/Mbed-TLS/mbedtls/pull/1620. But SM2/3/4 have not been added in recent versions(e.g., 3.6). I have implemented SM3, SM4 as standalone code( https://github.com/zliucd/cryptoshark), and want to port the code to Mbedtls while supporting SM2. However, to fully support the two new cipher suites, we need to add lots of other code. The first step is to add SM2, SM3 and SM as standalone ciphers. Thanks for any comments. Zhi

EAP TLS - TLSv1.2 Record Layer: Alert (Level: Fatal, Description: Unknown CA)

by Satya Prakash Prasad

Hi, I am not sure if this questions should be addressed to this support team but in hope that some positive information might come up. I am trying to analyze an SSL handshake failure issue. Based on the issue please find below steps to create client / server certificates. : openssl genrsa -out ca.key 2048 openssl req -new -x509 -days 1826 -key ca.key -out ca.crt openssl genrsa -out server.key 2048 openssl req -new -out server.csr -key server.key openssl x509 -req -in server.csr -CA ca.crt -CAkey ca.key -CAcreateserial -out server.crt -days 360 At this step I have below files: ca.crt (which I use as trusted_client.pem), server.crt and server.key at server side Client Side certificate generation: openssl genrsa -out client.key 2048 openssl req -out client.csr -key client.key -new openssl x509 -req -in client.csr -CA ca.crt -CAkey ca.key -CAcreateserial -out client.crt -days 360 So now at client side I have below files: client.crt client.key trusted_client.pem [generated during Server certificate step] I am not sure if I have generated the certificates correctly - but I am trying to test a Mutual trusted Server / Client SSL connection. So there is no certificate chain I have made during their certificate creation - they are self-signed ones. Note that when asked about the CN I gave "CA" (for CA), "example.com" (for server) and "client" (for client). When I run the flow I get below error: TLSv1.2 Record Layer: Alert (Level: Fatal, Description: Unknown CA) Wireshark logs: 103 2024-04-01 11:17:42.886627 Device_00:8c:94 Nearest-non-TPMR-bridge EAPOL

Assistance Requested: TLS Handshake Failure with MbedTLS on STM32F4

by Ashvajit Prasad

Hello Mbed-TLS team, I am reaching out for guidance on an issue I've encountered while integrating MbedTLS for HTTPS requests using the coreHTTP stack alongside FreeRTOSplusTCP on an STM32F4 device. Although I have successfully implemented an HTTP client, moving to HTTPS has presented some challenges. My approach has included several adjustments to the mbedtls_config file, such as: - Integrating a Random Number Generator (RNG) from STM32 within the mbed_Entropy_poll function. - Utilizing the calloc and free functions provided by FreeRTOS. - Modifying the search algorithm to correctly handle null-terminated PEM certificates. Despite these efforts, I am unable to establish a connection to the server, with the process consistently failing during the TLS handshake phase. Specifically, the client hello message is transmitted from my device, but no response is received from the server, resulting in an MBEDTLS_INTERNAL_ERROR. Enclosed with this email are my mbedtls_config file and a detailed account of the issue as posted on the FreeRTOS forum<https://forums.freertos.org/t/integration-of-ssl-in-corehttp/19561/11>. While I do not expect a full code review<https://github.com/AshvajitP/Eth_FreeRTOS_F4>, any insights into potential causes for this type of handshake failure would be greatly appreciated. Thank you for your time and assistance. Regards, Ashvajit Prasad

Status of RFC 8449 support

by norbert.fabritius＠esrlabs.com

I saw the following comment when configuring Record Size Limit Extension (RFC 8449) in `mbedtls_config.h` [1]: > This extension is currently in development and must NOT be used except for testing purposes. Is this still accurate? What functionality is missing for full RFC 8449 support? Is this feature planned for a specific date?

MBedTLS Integration API Implementation

by Satya Prakash Prasad

Hi, We are integrating https://github.com/prplfoundation/hostap code into our project that makes uses of crypto and SSL functionality. Their code is so written that they have interfaces defined where crypto and SSL 3rd party algorithms can be called and implemented. We are stuck implementing those APIs interfaces using MBedTLS and in need of help for its implementation. Referring to the below set of interfaces as defined in https://github.com/prplfoundation/hostap/blob/master/src/crypto/tls_none.c we need to implement required code for MBedTLS. I am in need help implementing below API: struct tls_connection * tls_connection_init(void *tls_ctx) where tls_connection is below defined type [user defined type - hope is correct implementation]: struct tls_connection { mbedtls_ssl_context *ssl; keyman_creds *cr; }; We have made the below implementation struct tls_connection * tls_connection_init(void *ssl_ctx) { mbedtls_ssl_context *mssl_ctx = ssl_ctx; struct tls_connection *conn; conn = os_zalloc(sizeof(*conn)); if (conn == NULL) { return NULL; } conn->ssl = mssl_ctx ; conn->cr = NULL; mbedtls_ssl_set_bio(ssl_ctx, NULL, net_send, net_recv, NULL); return conn; } If my above implementation is correct please let me know how to implement our own net_send and net_recv function. There are many buffer declaration in mbedtls_ssl_context I am not sue what algorithm to use to read complete / remaining bytes using internal data structure : int net_recv(void *ctx, unsigned char *buf, size_t len) { /* how to implement */ } int net_send(void *ctx, const unsigned char *buf, size_t len) { /* how to implement */ } Thanks in advance.

MBedTLS PSA

by Satya Prakash Prasad

Hi, Please also let me know the features of PSA in MbedTLS. I found this related document - https://mbed-tls.readthedocs.io/en/latest/getting_started/psa/. Is PSA related to Platform Security Architecture or is related to TLS security? How will the inclusion and non-inclusion of PSA will differ in terms of security? Thanks in advance. Regards, Prakash

Build bignum module only

by Liu Blade

Hello, Bignum is a very useful feature in Mbedtls, which is a part to libmbedcrypto.a. I want to build this module only as a standalone static library. However, I find it's difficult to modify CMakelists.txt to do this. I appreciate your suggestions. Blade

MBed TLS - Generic Question

by Satya Prakash Prasad

Hi Team, Referring to MBed release page - https://github.com/Mbed-TLS/mbedtls/releases?page=1 I see that there has been constant release periodically from Jul 27, 2018 mbedtls-2.1.14 till Nov 8, 2023 v3.5.1. In the same context I understand that with each release there have been fixes and new features / enhancement implementation. There was a project that I was working in year 2020 were we tried to integrate MBed TLS in EAP https://github.com/prplfoundation/hostap. It was a practice exercise that our team did that time. I have not much idea as to which MBed TLS version was opted and integrated then. Now that so many new releases are made after 2020 - are older versions can be taken as stable? Is it that we should take the latest version and try again from scratch? Thanks in advance. Regards, Prakash

ssl session cache does not work in firefox

by Jan Pohanka

Hello, I have a simple http(s) server running on embedded platform using mbedtls. Using ssl session cache significantly improves the throughput. However while it works flawlessly in chromium based browser I noticed that in Firefox it does not work at all. Following there is a short snippet of my accept routine. Am I doing something wrong? ... mbedtls_ssl_conf_session_cache(&ssl_ctx->conf, &server_cache, mbedtls_ssl_cache_get, mbedtls_ssl_cache_set); mbedtls_ssl_init(*ssl); rc = mbedtls_ssl_setup(*ssl, &ssl_ctx->conf); if (rc < 0) { mbedtls_ssl_free(*ssl); mg_free(*ssl); *ssl = NULL; return -ENOMEM; } mbedtls_ssl_set_bio(*ssl, sock, mbedtls_net_send, mbedtls_net_recv, NULL); rc = mbed_ssl_handshake(*ssl); ... best regards Jan

Importing ECC privatekey (from PEM) into PSA and mbedtls_ecp_export undefined reference error

by mathi.naickan＠gmail.com

Hi, Iam trying to import an ECC privatekey(parsed through mbedtls_parse_key()) to PSA (psa_import_key()) (for ECDSA NIST-P256-SECP-R1), by following the suggestions here ==> https://github.com/Mbed-TLS/mbedtls/blob/development/docs/psa-transition.md (under the heading - Importing a PK key by export-import for an ECC private key). But, i get an undefined reference to `mbedtls_ecp_export' error. Is there a special flag that controls this? I can see that the definition of this function does exist in ecp.c. Kind Regards, Mathi.

MbedTLS (2.25.0) TLS handshake on FreeRTOS - PSA Crypto enabled (SE) but not used during client step 8

by hippolyte.einfalt＠viveris.fr

Greetings, ## The Setup Greetings, ## The Setup I have a RENESAS board that has an integrated crypto processor and uses MbedTLS 2.25.0. I have a SE (secure element) connected to it. I am allowing hardware acceleration and PSA crypto API inside mbedtls_config.h I registered my SE driver before calling psa_crypto_init(). The board connects to a web server and performs TLS handshake with the forced cipher `MBEDTLS_TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256`. ## The issue The handshake fails during the step 8 when generating EC private key for ECDHE exchange. I have tracked the issue through debug and it unfolded as follows inside `ssl_write_client_key_exchange()`: - We enter the PSA crypto code from the pre-processor directives. - We set the key attributes after initializing them to 0. (here usage_flags, algorithm, type and bits field are set but lifetime is still 0 from init at this point, this will count later on) - The next function `psa_generate_key()` fails. ## In depth When inside the `psa_generate_key()` function, we start the key creation inside `psa_start_key_creation()`. But here, when validating the attributes of the key in `psa_validate_key_attributes()`, we are not able to rely on the SE to store the key due to it being volatile (lifetime is still 0), the driver is never called. From there the program keeps going until trying to generate the key with the crypto processor from the board which does not support this type of key and returns unsupported error. ## Main question Since the lifetime is forced to be representing a volatile key and since the driver for the SE is not called except for persistent ones, i cannot do this cryptographic step using the SE. Is the generation of the volatile key at this step meant to be handled by the MbedTLS library (software or hardware alt) and not by the PSA Crypto API (SE) due to the key being volatile ? If not, how is the Se supposed to be called in the handshake and what am i missing ? ## Discussion I can pass the handshake when disabling hardware acceleration and using the software for cryptographic steps, but in this case i am not using the SE for them. Should the SE only be used to store the client certificate for mTLS case ? ## Note I must use the MbedTLS version 2.25.0 since the SE driver I am using relies on this version.

Release all memory held by mbedtls_ssl_context

by Satya Prakash Prasad

Hi, We are writing a client code which can accept or decline connection to the server - so for each connection I understand there is a mbedtls_ssl_context data established. Once the same is closed or not required we need to do deinitialize or free memory allocated to its member variables like - we need to free all memory allocated since we need it back else our application will run out of memory like: os_free(mbed_ctx->handshake); os_free(mbed_ctx->transform_negotiate); os_free(mbed_ctx->session_negotiate); os_free(mbed_ctx->in_buf); os_free(mbed_ctx->out_buf); But there are many member variables which also need to free memory if allocated and assigned to it. Is there a function / method that can free all memory for mbedtls_ssl_context instance variable? Thanks in advance. Regards, Prakash

EAP TLS

by Satya Prakash Prasad

Hi, I am working on an issue related to memory leak in MBedTLS. We have integrated MBedTLS code for below 3rd party HostAPD code integration . https://github.com/prplfoundation/hostap [Hostapd] Please refer to the Hostapd peer code implementation as provided in the link below: https://github.com/prplfoundation/hostap/blob/master/eap_example/eap_exampl… https://github.com/prplfoundation/hostap/blob/master/eap_example/eap_exampl… The main function code snippet is provided below: https://github.com/prplfoundation/hostap/blob/master/eap_example/eap_exampl… if (eap_example_peer_init() < 0 || eap_example_server_init() < 0) return -1; do { printf("---[ server ]--------------------------------\n"); res_s = eap_example_server_step(); printf("---[ peer ]----------------------------------\n"); res_p = eap_example_peer_step(); } while (res_s || res_p); Since we are implementing code for peers hence we have removed the server step. Now we need to keep monitoring for new connections / failed connections and act accordingly we have modified the code to something like below - if (eap_example_peer_init() < 0 || eap_example_server_init() < 0) return -1; do { res_p = eap_example_peer_step(); if (eap_ctx.eapNoResp || eap_ctx.eapFail) { eap_client_peer_deinit(); eap_client_peer_init(); } } while (1); We have modified the loop such that it will keep iterating for new connections and in case of failure, re-initialization is required. Is my understanding correct? The issue I am facing is that the client peer deinit method is not releasing all memory allocated during eap_example_peer_step() function ( I understand while processing the EAP TLS server request). The deinit is purely implemented to deallocate memory initially allocated for a new connection using TLS? void eap_client_peer_deinit(void) { eap_peer_sm_deinit(eap_ctx.eap); eap_peer_unregister_methods(); wpabuf_free(eap_ctx.eapReqData); os_free(eap_ctx.eap_config.identity); os_free(eap_ctx.eap_config.password); os_free(eap_ctx.eap_config.cert.ca_cert); os_free(eap_ctx.eap_config.cert.client_cert); os_free(eap_ctx.eap_config.cert.private_key); } where void eap_peer_sm_deinit(struct eap_sm *sm) { if (sm == NULL) return; eap_deinit_prev_method(sm, "deinit"); eap_sm_abort(sm); if (sm->ssl_ctx2) tls_deinit(sm->ssl_ctx2); tls_deinit(sm->ssl_ctx); eap_peer_erp_free_keys(sm); os_free(sm); } Can you please let me know whether we are deallocating memory correctly? Thanks in advance. Regards, Prakash

Handshake is successful if the intermediate CA is revoked.

by singaravelu Balasubramani

I am checking the certificate revocation with below scenario. I have Root CA, Intermediate CA and device certificate is signed by Intermediate CA. I am makeing chain certificate by combining Root CA, Intermediate CA and this chain certificate is my active CA certificate and loaded this and device certificate to the drive. From client, I am creating client certificate which is signed by same intermeidate CA. Making ssl handshake. Handshake is success as expected. Now i am revoking the intermediate CA and creating the crl which is signed by the Root CA. This crl has the serial number of intermediate CA. Now loading the CRL to the drive and setting the crl in "mbedtls_ssl_conf_ca_chain". Now i am establishing the ssl connection with the same client ceritificate and expecting the ssl handshake failure due to intermediate CA revoked. But i get handshake is success. Is my understanding right about intermediate CA revocation? I did little background debug, and my obervation is During handshake , it goes to static int x509_crt_verify_chain function in mbedtls. Its trying to find the parent using x509_crt_find_parent for the client certificate and get intermediate CA. During this time, parent_is_trusted is set as true. after this x509_crt_verifycrl is called with client certificate (child), intermediate CA (parent) and crl(has the intermediate CA serial number-issued by Root CA). During x509_crt_verifycrl check, it check for CRL issuer with ca subject and return 0, as its not matching. now in x509_crt_verify_chain , /* prepare for next iteration */ ., they are marking child_is_trusted = parent_is_trusted and child = parent, parent = NULL; and while loop continues, in loop, x509_crt_verify_chain checks for child_is_trusted is true and return as 0. But its not checking that intermediate CA is revoked or not. /* Stop here for trusted roots (but not for trusted EE certs) */ if( child_is_trusted ) return( 0 );

Question about mbedtls_x509_parse_subject_alt_name

by Roman Janota

Hello, I would like to parse certificate's SAN fields in my application. In the documentation of the struct mbdetls_x509_crt for its member subject_alt_names the following is stated: "Optional list of raw entries of Subject Alternative Names extension. These can be later parsed by mbedtls_x509_parse_subject_alt_name.". I was using the latest development branch and tried to call the function, however, I found out I can not, because it is defined in the x509_internal.h private header. I later found out that the definition was moved from the public to the private header in the commit 25b282e <https://github.com/Mbed-TLS/mbedtls/commit/25b282ebfe5cb84e73d6194e83dc8d6c…> (partly thanks to the issue #459 <https://github.com/Mbed-TLS/mbedtls/issues/459>). So I switched to the 3.5.2 release and everything worked fine. Why was this change made? Will it be kept so that I'd have to implement my own parsing? Or was it a mistake? Thank you for clarifying, Roman.

Public And Private Keys

by Satya Prakash Prasad

Hi, I need some clarification on Public and Private keys that a server maintains its own side. All documents say that the client will use the server's public key to encrypt the data while the server will make use of its private keys to decrypt. Is it not that the data can be decrypted using the public key itself? How and what is encryption logic implemented in such a case? Please do provide some logical explanation for the same - how does this encryption / decryption work? Regards, Prakash

ECDH - establish shared secret key with X509 certificate + private key

by Tilen MAJERLE

Dear community, My target is to establish a shared secret key between the PC application (master) and (various, different, but always limited to 1 at a time) peripheral devices. *Each device has*: - Device specific ECC 256-bit private key, in PEM format, well parsed with mbedtls_pk_parse_key function when required. - Device specific certificate that belongs to the private key. Certificate is signed by the *TrustCA*. Parsing works well with mbedtls_x509_crt_parse - TrustCA’s certificate, used to validate the master device during communication, also used to check firmware signature in a secure boot part of the application *PC application has*: - Master application certificate, signed by *TrustCA* - Private key of the PC application that belongs to master application certificate, in PEM format - *TrustCA*’s certificate, used to validate device certificate during communication Aim is to establish AES shared secret, by doing: - Master sends authentication requests, random challenge, device performs hash + signs with private key. Returns certificate + signature of the challenge. - Master uses *TrustCA*'s certificate to check device's certificate and then checks the signature of the hash(challenge) - Master sends its certificate to the slave, now both hold X509 certificates. At this point, device could also request authentication of the PC application - A computation with its respective private key is needed on both sides, and we have common secret. What is the correct way in mbedTLS, to get a public key from *X509*, that can be used in the ECDH module? The way the ECDH module inside mbedTLS seems to be designed, there is no straight-forward way to export X5090’s public key, get its parameters and use them in ECDH module. Instead, ECDH expects that random keypair will be generated every-time we want key exchange. Doing this, we risk *man in the middle* attack, since the other party doesn’t know where the key is actually coming from. For the moment, the solution I see (which is not THAT elegant, or is it?), and to avoid man in the middle attack:: - Devices still exchange certificates, but only for authentication reason + certificate verification - Every message that is sent between devices (for instance public keys exchange), must also be hashed & signed, so that another party can be sure message is coming from the device which shared the certificate just before (and certificate is signed by TrustCA) - We need one exchange more to get shared secret. Is this the *proposed* solution in this case? Is there a more elegant solution with the mbedTLS library for this problem? Thanks -- Tilen Majerle, mag.inž.el.

Dropping support for Visual Studio 2015

by Gilles Peskine

Hello, We are considering dropping support for Visual Studio 2013 and Visual Studio 2015 from Mbed TLS 3.6 onwards. This would make Mbed TLS 3.6 require Visual Studio 2017 or newer. (Mbed TLS 2.28 LTS is not affected.) Per the Visual Studio product lifecycle <https://learn.microsoft.com/en-us/visualstudio/productinfo/vs-servicing#old…>, VS 2013 and 2015 are currently on extended support, but their support will end during the lifetime of Mbed TLS 3.6 LTS. Our reasons are: * We prefer not to support products that are not supported upstream, such as VS 2013 and 2015 will be during the lifetime of 3.6 LTS. * Older versions of Visual Studio tend to require workarounds due to their incomplete support for C99, and we would like to reduce those. We may drop support for older versions of MinGW as well for this reason. * The development branch of Mbed TLS is currently triggering an internal compiler error in VS 2015 <https://github.com/Mbed-TLS/mbedtls/issues/8735>. If you want to keep support for VS 2013 and 2015 in Mbed TLS 3.6, please let us know as soon as possible and tell us why it's important. Assistance with the internal compiler error would be appreciated. Best regards, -- Gilles Peskine Mbed TLS developer

MBed TLS

by Satya Prakash Prasad

Hi, I was referring to below URLs for understanding key exchange using certificate in TLS framework: https://tls12.xargs.org/ https://tls13.xargs.org/ I have some confusion related to above TLS 1.2 and 1.3 flows and require guidance from your side accordingly. I understand the key exchange using certificates highly depends on configuration and capabilities setup. But then how do we know what goes on a TLS connection based on configuration and setup capabilities? What are the different configurations and when should we set them? I need the same details with reference to a TLS connection setup from a client in our codebase while other for EAP TLS using the below example available in the url below: https://github.com/prplfoundation/hostap/blob/master/eap_example/eap_exampl… Firstly in the above code we do see a lot of configuration and initialization like below: eap_cb.get_config = peer_get_config; eap_cb.get_bool = peer_get_bool; eap_cb.set_bool = peer_set_bool; eap_cb.get_int = peer_get_int; eap_cb.set_int = peer_set_int; eap_cb.get_eapReqData = peer_get_eapReqData; eap_cb.set_config_blob = peer_set_config_blob; eap_cb.get_config_blob = peer_get_config_blob; eap_cb.notify_pending = peer_notify_pending; Whereas our client code which connects to the cloud using certificates to obtain some data in below mentioned way: keyman_creds_for_purpose() - get the creds read and parse the crt.pem, key.pem and trusted_ca.pem files. It make uses of below APis:readfile() - read the file from key storageparse_private_key() & mbedtls_pk_parse_key() - I believe it is for parsing the keys read from file Setup MBed TLS mbedtls_ssl_config_init() - Initialize mbedtls_ssl_configmbedtls_ctr_drbg_init() - CTR_DRBG context initialization mbedtls_ctr_drbg_seed() mbedtls_ssl_conf_rng() mbedtls_ssl_conf_ca_chain() mbedtls_ssl_conf_own_cert() mbedtls_ssl_conf_authmode() t_socket() I am quite new to this code so could have missed or provided wrong info - but I hope I give the overall picture of code implementation - note that this client code is a working code with no issues. My queries are mentioned below: 1) Does the same TLS message flow occur in both cases - our client code and EAP TLS? If not then what's the difference in-between them? 2) How do we understand exact implementation and message flows? 3) What are the different ways to implement TLS connection using certs? 4) Any additional information that can helpful to me like - some references to tutorials / examples / guide would be an added advantage Thanks in advance.

Optimized swap and endianness macros (MBed TLS 2.28.x)

by jojwoos

Hi, when upgrading MBed TLS from 2.16.x to the LTS 2.28.x version on an ARM 32 bit system, I realized that the byte-order macros were collected to one file (common.h) with the possibility to replace them. After writing ARM optimized macros, I checked this topic in the 3.5.x version where it was implemented in a similar way in alignment.h. With this input the following solution was made for the 2.28.x branch: https://github.com/jojwoos/MbedTLS_wrapper A bit late, but maybe someone can still use it:) Perhaps the 64 bit swap, build from two optimized 32bit swaps, can provide some input for the actual 3.5.x version. You can find it at: "// general 64 bit optimization if only 32 bit optimization is available" (32bit ARM systems usually don't have optimized 64bit swap functions) Best regards, Jürgen

MBed TLS Tutorial

by Satya Prakash Prasad

Hi, Referring to the example as in https://mbed-tls.readthedocs.io/en/latest/kb/how-to/mbedtls-tutorial/ (secure connection) does the secret key exchange takes place in-between server and client. Is there any flowchart / diagram that states what happens during the server client connection - how the keys are exchanged and what types of certs are exchanged, I mean like .pem, X.509 etc? Can we take this way that be it any type of certificate the code implementation is the same for all TLS communication? Thanks in advance. Regards, Prakash

Apt error for invalid key ID

by S Krishnan, Archanaa

Hello, In psa_validate_key_attributes(), when the key ID is invalid for persistent keys the function returns PSA_ERROR_INVALID_ARGUMENT. See https://github.com/Mbed-TLS/mbedtls/blob/development/library/psa_crypto.c#L…. The comments for PSA_ERROR_INVALID_ARGUMENT explicitly states that this error should not be returned when key identifier is invalid, instead PSA_ERROR_INVALID_HANDLE should be returned. For the above psa_validate_key_attributes() usecase, which is the correct return code - PSA_ERROR_INVALID_ARGUMENT or PSA_ERROR_INVALID_HANDLE? Regards, Archanaa

Request for comments on adding more MBEDTLS_PRIVATE accessors.

by Minos Galanakis

Hi all. We are currently planning on improving our coverage and adding accessor functionality for members marked as MBEDTLS_PRIVATE. I have created an issue ( #8529 )<https://github.com/Mbed-TLS/mbedtls/issues/8529> to consolidate all the information and design-review the task. It would really help to hear from the community as to which members they are still using, and what is their use-case. Feel free to comment on the issue, or discuss it here. There may be members that we have decided not to include and are essential to your integration or are completely missing/not being considered. Best Regards, Minos Galanakis

MbedTLS Code 3.5.1

by Satya Prakash Prasad

Hi, We need to integrate the TLS Code in our codebase. I have downloaded Mbed TLS 3.5.1 @ https://github.com/Mbed-TLS/mbedtls/releases and compiled it. I understand that we can just use the code in mbedtls-3.5.1\library directory for the TLS functionality - can anyone please confirm. Are there any other directories where TLS Code exists in the MbedTLS 3.5.1 repo? Please confirm how we can only integrate MbedTLS TLS functionality code in other applications / repo. There are so many other directories in MbedTLS 3.5.1 repo - how is the code in repo organized? Do we need all the code in MbedTLS 3.5.1 repo? Your valid input will help me to integrate the MbedTLS Code in our codebase? Please provide all other details as required or will be helpful for the same. Thanks in advance. Regards, Prakash

Code samples for psa_import_key and ECC?

by Christian Huitema

I am trying to use psa_import_key() after loading private keys from PEM files. I am succeeding when parsing an "RSA PRIVATE KEY", but no such luck for "EC PRIVATE KEY". I assume that I am not setting attributes correctly. A code sample would be nice! Or, maybe I could just use mbedtls_pk_parse_keyfile(), but then I would need to "import" a PSA key from the "mbedtls" context, ad I did not find sample code for that either. -- Christian Huitema

Mbed TLS license change

by Dave Rodgman

Hi Mbed TLS users, We are planning to change the license for Mbed TLS shortly, from Apache 2.0 to a dual license Apache 2.0 / GPLv2-0-or-later license. This will allow GPL-licensed projects to take Mbed TLS under a GPL license. Projects which currently take Mbed TLS under an Apache 2.0 license may continue to do so, and therefore should not be affected by this change. The inbound license, under which we accept contributions, is already a dual-license. There is therefore no impact for contributors, and no impact on PRs that are currently in review, or those that have previously been integrated into the library. We hope that this will enable more projects to make use of Mbed TLS. Dave Rodgman

TF-PSA-Crypto publication

by Ronald Cron

We are happy to announce the publication in GitHub of the TF-PSA-Crypto repository: https://github.com/Mbed-TLS/TF-PSA-Crypto. The TF-PSA-Crypto repository provides an implementation of the PSA Cryptography API (https://arm-software.github.io/psa-api). This encompasses the on-going extensions to the PSA Cryptography API (e.g. PAKE). The PSA Cryptography API implementation is organized around the PSA Cryptography driver interface aiming to ease the support of cryptographic accelerators and processors. This is a significant milestone on the journey to split the PSA Cryptography API implementation and its development out of the Mbed TLS repository into TF-PSA-Crypto. This is early days though and the TF-PSA-Crypto repository should be considered as a prototype: it is read-only and mostly a mirror of the PSA Cryptography API implementation of Mbed TLS. But we believe it is a good illustration of what we are aiming at. Thanks, Ronald Cron on behalf of the Mbed TLS team.

How to implement Opaque driver API

by Jiamei Xie

Hi experts, I wanted to forward some crypto operations to an external driver that provides psa_call APIs. The mbedtls version I am using 3.4.0. Take psa_asymmetric_encrypt as an example, The mbedtls api is psa_status_t psa_asymmetric_encrypt(mbedtls_svc_key_id_t key, psa_algorithm_t alg, const uint8_t *input, size_t input_length, const uint8_t *salt, size_t salt_length, uint8_t *output, size_t output_size, size_t *output_length) It gets attribute, key.data and key.byte from key_id. Then call function psa_driver_wrapper_asymmetric_encrypt without key_id as its argument: status = psa_driver_wrapper_asymmetric_encrypt( &attributes, slot->key.data, slot->key.bytes, alg, input, input_length, salt, salt_length, output, output_size, output_length); In psa_driver_wrapper_asymmetric_encrypt, it will use different implementations according to the location value in https://github.com/Mbed-TLS/mbedtls/blob/d69d3cda34c400a55220352518e37d3d2c…. I define a new location definition(RSS_PSA_LOCATION. When the location is RSS_PSA_LOCATION, making it call psa_status_t crypto_psa_asymmetric_encrypt(psa_key_id_t key, psa_algorithm_t alg, const uint8_t *input, size_t input_length, const uint8_t *salt, size_t salt_length, uint8_t *output, size_t output_size, size_t *output_length) This API require key_id. Is it possible to get key_id from attribute and key_slot? Regards, Jiamei Xie

Driver only build option

by Ruchika Gupta

Hi, I am trying to use the MACRO's defined at - https://github.com/Mbed-TLS/mbedtls/blob/development/docs/driver-only-build… to enable driver only build. As mentioned on the page I tried to do this for SHA256. However, the code in sha256.c isn't ifdefed by "MBEDTLS_PSA_ACCEL_ALG_SHA_256" so still gets compiled ? Can you point me to what I am missing here ? Regards, Ruchika

How can I encrypt with a private key?

by 克坚马

Hi all, I have been using the old version(2.28) for a very long time, and updated to version 3.4.0 recently. When using rsa encryption, there is a parameter 'mode' that allows to choose whether to use a public key or a private key. Why is it canceled in the new version? And how can I use the private key to perform an encryption operation? Thank you for your help!

PSA crypto driver - KEY LOCATIONS

by Ruchika Gupta

Hi, For the crypto accelerator, we are developing for our SoC, we have a use-case where the same driver can support multiple/range of KEY LOCATIONS. We want a mechanism such that, the a common function in driver is called which can then take the necessary option based on the key location. The way jsons are currently structured, what I understand is that for every key location, we will need to create a separate json with a different driver prefix. This would lead to a lot of code duplication for us. For eg { to define 3 locations X, Y and Z , I need to create 3 json files -> these all refer to same crypto sub-system I my case} #define TEST_DRIVER_X_OPAQUE_DRIVER_ID #define TEST_DRIVER_Y_OPAQUE_DRIVER_ID #define TEST_DRIVER_Z_OPAQUE_DRIVER_ID Switch (key_location) Case x: Test_driver_x_ opaque_import_key(); break; Case y: Test_driver_y_ opaque_import_key(); break; Case z: Test_driver_z_ opaque_import_key(); break; This is resulting in a lot of code duplication and overhead. What we want to have the flexibility to achieve is : #define TEST_DRIVER_OPAQUE_DRIVER_ID Switch (key_location) Case x: Case y: Case z: Test_driver_opaque_import_key(); If we can support multiple locations from a driver json file for a given driver, this issue would be resolved. This would give the driver writers flexibility on how and where they want to handle the locations. Please let us know your views on the same. Regards, Ruchika

psa_raw_key_agreement does not like PSA_ALG_ECDSA(PSA_ALG_SHA_256)

by Christian Huitema

I am not sure I completely understand the PSA API for key exchange. I have been creating a private key, exporting the public key, passing that successfully to the peer, obtaining the peer's public key, and I want to use psa_raw_key_agreement to obtain the shared secret. But it fails in: if (!PSA_ALG_IS_KEY_AGREEMENT(alg)) { status = PSA_ERROR_INVALID_ARGUMENT; goto exit; } The value of "alg" is 0x06000609, computed as PSA_ALG_ECDSA(PSA_ALG_SHA_256). That's probably wrong, but I do not know why... -- Christian Huitema

Output format of mbedtls_ecdh_make_params does not play well with TLS 1.3

by Christian Huitema

In TLS 1.3, one half of an ECDH exchange is defined as a "key entry", coded as: struct { NamedGroup group; opaque key_exchange<1..2^16-1>; } KeyShareEntry; The opaque data is typically encoded as a one byte format (e.g., 0x04, no compression), and then the encoding of either one or two points: 32 bytes for one point with CURVE25519, 64 bytes for two points with SECP256R1. The encoding for the "public key" output of mbedtls_ecdh_make_params is different: 1 byte of length, followed by 2 bytes of curve ID, followed by the raw encoding of the point or points. The related encoding of the server public key output of mbedtls_ecdh_make_public is also different: 1 byte of length, followed by 2 bytes of curve ID, followed by the raw encoding of the point or points. To make that work, I need some reformatting: strip out 3 bytes for the client public key, write a single 0x04 byte instead; strip out one byte from the key-exchange data received at the server and write 3 bytes of length and curve ID instead. Also, make sure to reset the strings to the unmodified value before calling mbedtls_ecdh_calc_secret, which probably means maintaining two copies, thus twice the memory. This is a bit messy, and probably unnecessary. The extra parameters "length" is already passed through the API (the &olen argument) and the "group_id" could easily be passed as well. Or maybe I am looking at the wrong API... -- Christian Huitema

TLS handshake with AWS IoT MQTT broker seems to succeed and then is terminated by the broker

by Roger Sala

I am developing an AWS IoT MQTT client on STM32H723 using FreeRTOS 10.3.1, LwIP 2.1.2 and MbedTLS. My first attempt used MbedTLS 2.16.2 and it mostly works except that sometimes, seemingly related to the timing of the network I'm using, it fails when my client fails to send out anything after the Client Key Exchange message and then the server responds with a Close Notify as follows: "Time","Source","Destination","Protocol","Length","Info" "0.000000","10.24.108.94","54.157.158.237","TLSv1.2","418","Client Hello" "0.016460","54.157.158.237","10.24.108.94","TLSv1.2","150","Server Hello" "0.002777","54.157.158.237","10.24.108.94","TLSv1.2","685","Certificate" "0.000000","54.157.158.237","10.24.108.94","TLSv1.2","438","Server Key Exchange, Certificate Request, Server Hello Done" "0.976521","10.24.108.94","54.157.158.237","TLSv1.2","1006","Certificate, Client Key Exchange" "0.014853","54.157.158.237","10.24.108.94","TLSv1.2","61","Alert (Level: Warning, Description: Close Notify)" When it works it looks like this: "Time","Source","Destination","Protocol","Length","Info" "0.000000000","10.0.0.11","54.84.254.130","TLSv1.2","418","Client Hello" "0.017495225","54.84.254.130","10.0.0.11","TLSv1.2","150","Server Hello" "0.001743255","54.84.254.130","10.0.0.11","TLSv1.2","685","Certificate" "0.000022282","54.84.254.130","10.0.0.11","TLSv1.2","392","Server Key Exchange" "0.000004428","54.84.254.130","10.0.0.11","TLSv1.2","100","Certificate Request, Server Hello Done" "2.606030441","10.0.0.11","54.84.254.130","TLSv1.2","1326","Certificate, Client Key Exchange, Certificate Verify, Change Cipher Spec, Encrypted Handshake Message" "0.027421478","54.84.254.130","10.0.0.11","TLSv1.2","105","Change Cipher Spec, Encrypted Handshake Message" "0.000971482","10.0.0.11","54.84.254.130","TLSv1.2","193","Application Data" "0.075384354","54.84.254.130","10.0.0.11","TLSv1.2","87","Application Data" The last two "Application Data" messages are the MQTT connect and connect ACK, So before I filed a bug report, I upgraded to MbedTLS 2.28.4. The good news is that this client always (seems) to successfully negotiate the TLS handshake, but after receiving the first encrypted "Application Data" (connect), the broker immediately sends and "Encrypted Alert", which I'm taking to be a Close Notify because a TCP FIN follows shortly thereafter. The Wireshark capture of the 2.28.4 handshake looks almost exactly like the successful 2.16.2 handshake: "Time","Source","Destination","Protocol","Length","Info" "0.000000000","10.0.0.11","44.195.98.16","TLSv1.2","336","Client Hello" "0.018450117","44.195.98.16","10.0.0.11","TLSv1.2","150","Server Hello" "0.000524146","44.195.98.16","10.0.0.11","TLSv1.2","685","Certificate" "0.000003168","44.195.98.16","10.0.0.11","TLSv1.2","392","Server Key Exchange" "0.000002995","44.195.98.16","10.0.0.11","TLSv1.2","100","Certificate Request, Server Hello Done" "2.517148776","10.0.0.11","44.195.98.16","TLSv1.2","1329","Certificate, Client Key Exchange, Certificate Verify, Change Cipher Spec, Encrypted Handshake Message" "0.016572792","44.195.98.16","10.0.0.11","TLSv1.2","60","Change Cipher Spec" "0.000007326","44.195.98.16","10.0.0.11","TLSv1.2","99","Encrypted Handshake Message" "0.001500778","10.0.0.11","44.195.98.16","TLSv1.2","193","Application Data" "0.031014646","44.195.98.16","10.0.0.11","TLSv1.2","85","Encrypted Alert" ... except for the "Encrypted Alert" from the broker that leads to the closing of the session. I'm hoping someone has an explanation of the behavior I'm seeing and can suggest a path forward for me. Another data point is the fact that the client with MbedTLS 2.28.4 can successfully authentic and negotiate a TLS handshake with a mosquitto broker I'm running locally using self signed certificates. ====================================================================== The information contained in this e-mail, including all of its attachments, is confidential and proprietary information of IPG Photonics and its affiliates and intended only for the use of the individual or entity named above.

Does mbedtls support x509 certificates signed wih ED448 algorithm?

by Bahadır Maktav

Hi, I am trying to use a certificate with its public key algorithm is NIST P-384 and its signature algorithm is ED448. I am working on ESP board with IDF framework which supports mbedtls. But when I am trying to use that certificate, I got error message about 'MBEDTLS_ERR_X509_UNKOWN_SIG_ALG'. So, I thought that maybe mbedtls does not support certificates which signed with ED448.

Does mbedTLS TLS1.3 only support PSK?

by Thompson, Jeff

I've got mbedTLS 3.1.4 and want to use TLS 1.3. My handshake fails very early because I don't have any Pre-Shared Keys. Does mbedTLS TLS1.3 only support PSKs, or can I still use generated session keys as does TLS 1.2? If so, how?

Silly python problem when building on MacOS

by Christian Huitema

Hello, I am trying to build MbedTLS on a Mac, as part of a project to support MbedTLS in the "picoquic" implementation of QUIC. I have a small problem, probably something of my making. I have cloned the repo on an "mbedtls" directory, created a "build" subdirectory, and from there run"cmake ..", which worked fine, and then tried to run "make", which fails in "generating psa_crypto_driver_wrapper.c" when trying the python script "generate_driver_wrappers.py" because it cannot find the python module "jsonschema". I tried to solve that by installing that module using "pip", and test programs running python3 do find the "jsonschema". Calling print(jsonschema.__file__) shows the module is installed in my user directory: /users/christianhuitema/Library/python3.9/lib/python/... Is there a simple way to fix that? -- Christian Huitema

Certificate Revocation

by ahmed bouzid

Hello, I'm currently engaged in a project where I'm utilizing mbedtls for the management of certificates. Within this project, I'm aiming to integrate a revocation feature using Certificate Revocation Lists (CRLs). However, my search for resources on how to effectively implement a comprehensive certificate revocation process using mbedtls has unfortunately yielded no productive outcomes. I am concerned about how to first create a crl file and sign it using my self-signed CA, how to revocate a certificate if we need to revocate it, and how to update the CRL, then when parsing the cert how to detect that this certificate has been revocated. ( I am using LPCXpresso55S16 as a client and raspberry pi as a server and I am doing all with coding). Thank you in advance for your support. Best regards, Ahmed.

Custom MBEDTLS_CONFIG_FILE with CMake subproject

by mickael.bonjour＠cysec.com

Hello, I need some help to setup mbedtls as a CMake subproject, I added it as a subdirectory in my CMakeLists. However, I can't figure out how to use my own config file for mbedtls (MBEDTLS_CONFIG_FILE option to the file I want as a config file). When I put my custom config file to the include folder of mbedtls in the place of the original mbedtls_config.h file it works wel,l but it's not a future-proof option for me, is there anyone that could help me with this setup ?

Missing PSA wrapper for MAC verify

by Ruchika Gupta

Hi, I have noticed that PSA driver wrapper function is missing for single part MAC verify function. In the current implementation, it calls the MAC compute wrapper and does the comparison using mbedtls_psa_safer_memcmp. The hardware I am working on allows the complete process to be offloaded to it. Can we have an option for the same in wrapper layer for PSA for MAC verify ? Regards, Ruchika

mbedtls_pk_verify verify report MBEDTLS_ERR_RSA_VERIFY_FAILED

by yang ming

When `mbedtls_pk_verify` is used to verify digital signatures generated by openssl, the MBEDTLS_ERR_RSA_VERIFY_FAILED error occurs, openssl Specifies the command used to generate a certificate: ```bash openssl md5 -sign private.key -out sign test.md ``` But when I use `mbedtls_pk_sign(&pk_pri_ctx, MBEDTLS_MD_MD5, md, 0, sign_info, sizeof(sign_info), &size, mbedtls_ctr_drbg_random, &ctrl_drbg)` Generating the signature and using `mbedtls_pk_verify` results are successful, Print the signatures generated by mbedtls are not found to be the same as those generated by openssl. Please help。 mbedtls version: ```c #define MBEDTLS_VERSION_STRING "3.4.0" #define MBEDTLS_VERSION_STRING_FULL "mbed TLS 3.4.0" ``` openssl version: ```c OpenSSL 1.1.1 11 Sep 2018 ```

PSA crypto drivers

by Ruchika Gupta

Hi, I am currently working on PSA driver for our SoC's security crypto-processor. This processor needs to do some handling when a key is destroyed. In the current implementation in mbedTLS, I don't see a driver wrapper function available in psa_destroy_key(). Is there a specific reason for not having wrapper for driver function available for psa_destroy_key() ? Another query pertaining to the tests in the testsuite in mbedTLS. I was exploring if I could reuse the tests for the crypto-processor implementation. Have these been written with this kind of reuse in mind ? Basically I would like the ability to add driver location to the cases. The few cases I have looked at for psa seem to be very specific. Any pointers/suggestions if anyone is reusing this test suite to test their specific PSA drivers? Regards, Ruchika
