Question about using hardware-backed parameters in ALT crypto implementations

by Massimiliano Cialdi

Hi, I’m working with Mbed TLS 2.28.x on a microcontroller that provides a built-in crypto engine. The existing *_ALT support works fine for performance, and higher-level modules correctly route their block operations through the accelerated backend. On this platform the crypto hardware can also use internal key material stored in dedicated slots. These values are not accessible as byte arrays and cannot be passed to the usual setkey_*() API. Question Is there a recommended way to configure an ALT implementation so that it can select an internal key slot instead of receiving a buffer? Or, more generally, how should an ALT backend represent a key that is not exposed to software? Any guidance on the intended design would be appreciated. Thanks!

Security backports for v2.28

by Matt Bauman

Hello all, I know that v2.28.10 is EOL, but I've been working on bringing security bug fixes to our distribution of it as part of my work in shoring up the Julia package ecosystem. I've largely leaned on the Debian security team's work thus far; they have the much harder task of supporting 2.16.9 for bullseye (security) and have done great work in bringing that version up to date through CVE-2025-52497. I've re-landed their backport patches against v2.28.10; these can be found on our build tree [1] or my fork [2]: 1. https://github.com/JuliaPackaging/Yggdrasil/tree/54c5a3e8e72899a3a778d8617f… 2. https://github.com/Mbed-TLS/mbedtls/compare/v2.28.10...mbauman:mbedtls:v2.2… Now I'm faced with the daunting prospect of last week's CVE-2025-54764 and CVE-2025-59438. These are *much* larger changesets. Has anyone else begun tackling this? I very much appreciated the guidance that’s included in the advisory itself, but I'm guessing there may be others in our situation... and I came here looking to see if anyone had begun talking about this (or working on it) yet. Best, Matt

Question regarding mbedtls 3.6.0 conformance to IEC 62351-3:2023

by Tommaso Mancini

Hello, I am writing to you to ask if you have any available documentation you can share regarding mbedtls's conformance to IEC 62351-3:2023. For example: Do you know of any users which have implemented the library in systems that reached IEC 62351-3:2023 certification? Do you have a list of features mapped to the IEC 62351-3:2023 standard requirements? Perhaps a PICS template? Thank you in advance and apologies if this is the wrong channel for this kind of question.

Re: TrustedFirmware.org - Check for MbedTLS License/Royality fee for commercial usage

by Carina Tsai

To whom it may concern, Our engineering team is using the Mbed TLS library in our wifi range extenders sold on markets and adhere to the licensing terms outlined in the sourcecode and docs. Thanks to Shaun’s guideline, it would be no royalty if we adhere to the licensing terms. Is there any other cost required for us to use the Mbed TLS library in our wifi range extenders, adhering to the licensing terms outlined in the sourcecode and docs?
