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.

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

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: [CA certificates, ]. Please let me know if additional information Regards, Noushad Embedded systems engineer Inthings Technologies Private Limited www.inthings.tech<http://www.inthings.tech> [cid:image001.png@01DB65BA.1F5B9660]

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.

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.
