Mbed TLS 4.0.0-beta & TF-PSA-Crypto 1.0.0-beta releases.

by Minos Galanakis

I am happy to announce the joint-release of Mbed TLS 4.0.0-beta & TF-PSA-Crypto 1.0.0-beta PSA-Crypto now lives in its own repository while TLS and X.509 remain in Mbed TLS. This beta release breaks compatibility with earlier versions of Mbed TLS. Please do not use it in production. It’s intended for the community to verify codebase integrations against the split and API changes, and for early adopters to experiment and provide feedback. For full details, please see the release pages: Mbed TLS 4.0.0-beta: https://github.com/Mbed-TLS/mbedtls/releases/tag/mbedtls-4.0.0-beta TF-PSA-Crypto 1.0.0-beta: https://github.com/Mbed-TLS/TF-PSA-Crypto/releases/tag/tf-psa-crypto-1.0.0-…

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

Mbed TLS information request

by Solis, Hector

Hi! We are working with Mbed TLS 3.6.0 library and need the following information: 1. Is there any End-Of-Life date planned for this library? 2. What is the current version? 3. How can we obtain support for the library enquiries? Does this support has a cost? 4. How is the library update? Does this update has a cost? 5. Are this library Open Source? Thanks in advance for your help! 🙂 Have a great day! Héctor J. Solís Castillo Embedded Engr I Honeywell | HTS Building Automation 990, Av.

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!
