by MATRIX 小牧

Hello. I'm sorry for the sudden email. I have a question about mbedtls. Currently, HTTPS communication is performed by mbedtls with a microcomputer called esp32-wroom-32d. The following error occurs when validating the root certificate. --------------------------------------------- mbedtls: ssl_tls.c: 5808 x509_verify_cert () returned -12288 (-0x3000) --------------------------------------------- I can't find out the details even if I check the error code. Changing the certificate will eliminate the error. It has been confirmed that the certificate is legitimate and can be used. [SecurityCommunicationRootCA1.pem] ---- Success [SecurityCommunicationRootCA2.pem] ---- Failure I would like to have any information. Sorry for the unfamiliar English. I look forward to working with you. Komaki

Entropy PSA Crypto driver support

by François Beerten

Hi everyone, The PSA Crypto Driver Interface describes entry points for collecting entropy from drivers: |psa_status_t acme_get_entropy(uint32_t flags, size_t *estimate_bits, uint8_t *output, size_t output_size);| Currently, MbedTLS does not have any kind of support for those PSA driver entry points. I'm currently looking at trying to add initial support for those in the code. The idea is to write a very simple solution to get the ball rolling and that can be extended and improved later on. Is there interest for a patch to add this? There are different ways to integrate it into the current MbedTLS code. Do you already have plans or ideas on how it should be done? After multiple attempts locally, I've came up with an approach that can work well. Like for other PSA Crypto drivers, the entropy entry points would be listed in the generated "psa_crypto_driver_wrappers.c" file. Those entry points can then be used by a sub-function of mbedtls_entropy_gather(). What do you think of that approach? Best regards, François.

Re: License conflict with OpenVPN

by Dave Rodgman

Hi Max, Unfortunately, it would not be possible for us to re-license the project to GPLv2 - this would require agreement with all copyright holders of code contributed to Mbed TLS 2.17, which isn't feasible. For this reason I'm afraid we cannot offer an exception for individual projects.

Adding lists to the MBed TLS Tech Forum invite

by Don Harbin

Hi All, FYI, per Shebu, I'm adding both mbed-tls(a)lists.trustedfirmware.org and psa-crypto(a)lists.trustedfirmware.org to the MBed TLS Tech Forum invites. Please look for this in your inbox and accept it if you would like the series added to your calendar. - Note that this is a monthly meeting but you will see two invites, one that is for Asia timezones and one for Europe/US. Just delete the series that isn't timezone friendly for you. - FYI, recall that this and other tech forums can be found in the meeting calendar on the TF website <https://www.trustedfirmware.org/meetings/>. If you see a meeting in that calendar, click on the entry and an option comes up saying "copy to my calendar." It will import that single instance into your personal calendar from there if you wish. I wasn't able to test this feature with outlook, but it worked fine for google calendar. Please let me know if you have any questions. Best regards, Don Harbin TrustedFirmware Community Manager don.harbin(a)linaro.org

License conflict with OpenVPN

by Maximilian Fillinger

Hello! OpenVPN can be compiled with OpenSSL or mbedtls. However, OpenVPN is licensed under GPLv2 only. If I understand correctly, that means it is not legal to distribute binaries of OpenVPN that are linked with mbedtls 2.17 or later. At Fox Crypto, we produce a hardened version of OpenVPN, called OpenVPN-NL, for use by the Dutch government, which uses mbedtls. (The latest release is rather old and still uses 2.16.) Is there anyone I could ask about making an exception for linking OpenVPN with mbedtls? Regards, Max Fillinger

Tinycrypt performance & integration

by andrei.menzopol＠nxp.com

Hello, I want to test/analyze the performance increase of using tinycrypt for ECC operations instead of the standard MbedTLS ECC functions. Could you please help me with a few answers regarding this? I am aware that tinycrypt is already integrated in the baremetal branch. Do you happen to know what is the performance increase of using this tinycrypt uECC implementation instead of the standard one on arm cortex m4 microcontrollers? I would like to port the tinycrypt uECC changes from baremetal branch to a Mbed TLS 2.25.0 version used in Matter repo (from where Mbed TLS repo is refered), more exactly this commit: https://github.com/ARMmbed/mbedtls/tree/1c54b5410fd48d6bcada97e30cac417c5c7… What do you think is the best approach? I thought of forking Mbed TLS, creating a separate branch with that commit and adding there the tinycrypt changes from baremetal branch. However, I'm not sure how to proceed next since the Matter repo refers the MbedTLS repo. Is this approach ok? Thank you!
