Hello,

I would like to know if there is a planned release date for STM32H7 support with MbedTLS v3.

Thank you.

Hello @Moemen 

At this time, there are no commitments to upgrade the MbedTLS version included in STM32CubeH7.

You probably mean CubeMX doing it for you? :D

I wouldn't wait for that to happen.

Meanwhile, check this:

I'm actually adding MbedTLS manually to my project. What I wanted isn't the library itself but the alternative  implementations that come with it that enable the use of the CRYP and HASH peripherals for hardware acceleration. I guess I'll have to migrate the version I have of those alt files to make them work with MbdTLS v3.

So is ST serious and is not intending to offer modern and up-to-date drivers for mbedTLS in the future? mbedTLS 4.0 has been released and even 3.6 will be outdated soon.

How is ST expecting users to maintain their security software stacks if no updates are offered?

Hello @Moemen 

MbedTLS version 3.6.4 is now available on GitHub. Users are responsible for updating to this version as needed.

@Saket_Om May I suggest that ST adds updated version of those "alt" templates suitable for mbedTLS 3.6 to the forementioned stm32-mw-mbedtls git repo? That would help tremendously and offer an always up-to date crypto stack to users.
