support of Certificate exchange between client and server in Mbedtls

by Anupma Jain

Hi, In Embed tls version 2.28, is there any support to validate client certificate fields like for example: validity of certificate, CA validation or role extraction ? If support is present then, how can we enable that ? Please help me with this.Thanks in advance. Regards Anupma

totally beginner question...

by boddeke＠mac.com

hello, we are testing a secure communication and got example code that uses the mbed-tls library. i am using the online keil studio with mbed.org: created a new project (compiles fine) and added in the mbed-tls library but this already gives compile errors. see below. i am using the latest greatest versions (mbed-os 6.16.0 and mbedtls-3.2.1) and tried some older versions. all seem to give the same problems. see below. i have tried commenting out MBEDTLS_HAVE_TIME in mbedtls_config.h but that does not seem to make any difference tried different target boards, also no difference any help is greatly appreciated! thanks frank Build started Using toolchain ARMC6 profile {'ENV': {'ARMLMD_LICENSE_FILE': '8224@10.10.101.194:8224@10.10.109.222'}, 'PATHS': {'ARMC6_PATH': '/opt/ARMCompiler6.15.13/bin/', 'ARM_PATH': '/opt/armcc5_06_u6/'}, 'common': ['-c', '--gnu', '-O3', '-Otime', '--split_sections', '--apcs=interwork'], 'cxx': ['--cpp', '--no_rtti'], 'COMPILE_C_AS_CPP': False, 'NEW_SCAN_RESOURCES': True} scan /tmp/chroots/ch-59110c86-ee99-44c4-9ef0-79f3efde74a7/src scan /tmp/chroots/ch-59110c86-ee99-44c4-9ef0-79f3efde74a7/extras/mbed-os.lib compile mbed-os/cmsis/CMSIS_5/CMSIS/RTOS2/RTX/Config/RTX_Config.c compile mbed-os/cmsis/CMSIS_5/CMSIS/RTOS2/RTX/Source/TOOLCHAIN_ARM/TARGET_RTOS_M4_M7/irq_cm4f.S compile mbed-os/cmsis/CMSIS_5/CMSIS/RTOS2/RTX/Source/rtx_evflags.c compile mbed-os/cmsis/CMSIS_5/CMSIS/RTOS2/RTX/Source/rtx_lib.c compile mbed-os/cmsis/CMSIS_5/CMSIS/RTOS2/RTX/Source/rtx_mempool.c compile mbed-os/cmsis/CMSIS_5/CMSIS/RTOS2/RTX/Library/cmsis_os1.c compile mbed-os/cmsis/CMSIS_5/CMSIS/RTOS2/RTX/Source/rtx_evr.c compile mbed-os/cmsis/CMSIS_5/CMSIS/RTOS2/RTX/Source/rtx_memory.c compile mbed-os/cmsis/CMSIS_5/CMSIS/RTOS2/RTX/Source/rtx_delay.c compile mbed-os/cmsis/CMSIS_5/CMSIS/RTOS2/RTX/Source/rtx_msgqueue.c compile mbed-os/cmsis/CMSIS_5/CMSIS/RTOS2/RTX/Source/rtx_kernel.c compile mbed-os/cmsis/CMSIS_5/CMSIS/RTOS2/RTX/Source/rtx_mutex.c compile mbed-os/cmsis/CMSIS_5/CMSIS/RTOS2/RTX/Source/rtx_semaphore.c compile mbed-os/cmsis/CMSIS_5/CMSIS/RTOS2/RTX/Source/rtx_system.c compile mbed-os/cmsis/CMSIS_5/CMSIS/RTOS2/Source/os_systick.c compile mbed-os/cmsis/CMSIS_5/CMSIS/TARGET_CORTEX_M/Source/mbed_tz_context.c compile mbed-os/cmsis/CMSIS_5/CMSIS/RTOS2/RTX/Source/rtx_timer.c compile mbed-os/cmsis/CMSIS_5/CMSIS/RTOS2/Source/os_tick_ptim.c compile mbed-os/cmsis/CMSIS_5/CMSIS/RTOS2/RTX/Source/rtx_thread.c "time.h included in a configuration without MBEDTLS_HAVE_TIME" unknown type name 'time_t'; did you mean 'size_t'? unknown type name 'time_t'; did you mean 'size_t'? unknown type name 'time_t'; did you mean 'size_t'? compile mbed-os/cmsis/device/rtos/source/mbed_rtos_rtx.c In file included from /extras/mbed-os.lib/cmsis/device/rtos/source/mbed_rtos_rtx.c:23: In file included from /extras/mbed-os.lib/platform/include/platform/mbed_error.h:21: In file included from /extras/mbed-os.lib/platform/include/platform/mbed_retarget.h:107: /src/mbedtls/tests/include/baremetal-override/time.h:18:2: error: "time.h included in a configuration without MBEDTLS_HAVE_TIME" #error "time.h included in a configuration without MBEDTLS_HAVE_TIME" ^ In file included from /extras/mbed-os.lib/cmsis/device/rtos/source/mbed_rtos_rtx.c:23: In file included from /extras/mbed-os.lib/platform/include/platform/mbed_error.h:21: /extras/mbed-os.lib/platform/include/platform/mbed_retarget.h:669:5: error: unknown type name 'time_t'; did you mean 'size_t'? time_t st_atime; ///< Time of last access ^~~~~~ size_t /opt/ARMCompiler6.15.13/bin/../include/stdio.h:53:26: note: 'size_t' declared here typedef unsigned int size_t; /* see <stddef.h> */ ^ In file included from /extras/mbed-os.lib/cmsis/device/rtos/source/mbed_rtos_rtx.c:23: In file included from /extras/mbed-os.lib/platform/include/platform/mbed_error.h:21: /extras/mbed-os.lib/platform/include/platform/mbed_retarget.h:670:5: error: unknown type name 'time_t'; did you mean 'size_t'? time_t st_mtime; ///< Time of last data modification ^~~~~~ size_t /opt/ARMCompiler6.15.13/bin/../include/stdio.h:53:26: note: 'size_t' declared here typedef unsigned int size_t; /* see <stddef.h> */ ^ In file included from /extras/mbed-os.lib/cmsis/device/rtos/source/mbed_rtos_rtx.c:23: In file included from /extras/mbed-os.lib/platform/include/platform/mbed_error.h:21: /extras/mbed-os.lib/platform/include/platform/mbed_retarget.h:671:5: error: unknown type name 'time_t'; did you mean 'size_t'? time_t st_ctime; ///< Time of last status change ^~~~~~ size_t /opt/ARMCompiler6.15.13/bin/../include/stdio.h:53:26: note: 'size_t' declared here typedef unsigned int size_t; /* see <stddef.h> */ ^ 4 errors generated.

misc. questions

by Frank Bergmann

Hi all, I have some questions. 1) If you have an established TLS connection (mbed TLS 3.x) and while the connection is up the (server-) certificate expires: Will the connection stay up? Or is a new handshake (with valid cert) REQUIRED? 2) Related to question 1: CAN mbed TLS switch to a new cert on an existing TLS connection? (e.g. by doing another handshake from server OR client side) 3) With 3.x some struct members are now "private". Even if you can allow private access by a define it would be better to use a getter. But for ssl context's "state" I am missing this and also for "p_bio" (to access fd). Is there a chance to get this implemented? BTW - a big "LIKE" for 3.x! I really appreciate the changes. Thank you! kind regards, Frank

What is the URL to access the Mbed TLS knowledge base?

by Max Peng

Hi mbed-tls Team, I notice that https://tls.mbed.org has been directed to https://www.trustedfirmware.org/projects/mbed-tls/. However, I does not see any link to the old Mbed TLS knowledge base. It is a good resource for learning Mbed TLS. What is the URL to access it? Thanks, Max Peng

State of documentation

by Tim Becker

Hi all, it feels like the state of documentation has deteriorated since the last time I've used mbedtls (a couple of months ago). I'm not sure if the google index hasn't fully been updated yet, or I don't understand the new structure of the docs or ... Also, is this the proper forum to make suggestions? Should I raise an issue on Github? 1.) a lot of previously linked, useful information now redirects here: https://www.trustedfirmware.org/projects/mbed-tls/ which (please excuse my frankness) feels like an utterly useless abomination that only marketing people could love. - Some examples of previously useful links: from the wiki ( https://developer.trustedfirmware.org/w/mbed-tls/) : > Old Mbed TLS website > Documentation: Mbed TLS API Reference; Knowledge base; Dev corner all redirect to trustedfirmware.org ! As do nearly all the links in https://github.com/Mbed-TLS/mbedtls/blob/development/SUPPORT.md 2.) there is no longer an doxygen generated API documentation anywhere only. I could generate it myself, but then I'd need to get and install Doxygen, figure how to use it, etc. It would be great if this were restored. It can't be that expensive to host :) Anyway, it feels like I've been running around for hours trying to find _anything_ useful, but I just realized everything is redirected to trustedfirmware.org ... Is there any way to still access the old, useful docs? Thanks & sorry that this post is so negative, -tim
