Cryptographic hardware acceleration libraries for STM32F423

[MSaez.1]

I have download the TM32CubeExpansion_Crypto_V4.0.1 library. The folder structure doesn't look like the one represented in the UM1924 document. There is no AccHw_Crypto folder and no STMF1 to STMF4 folders nowhere.

Is there support for AES HW acceleration encryption for the STM32F423? Where can I find the libraries? The FW version is not working properly neither for my MCU or I am using them wrong. I did not find though an example for the AES CCM encryption/decryption.

Thank you and best regards

Hello @MSaez.1​ ,

the cryptolib V4 is a software implementation only.

There are no examples related to STM32F4 but you can use any example from L4 for instance as the library is tied to the Cortex Core.

You will need to make a small porting, adapting the clocking for instance.

The AES HW acceleration can be used through HAL libraries.

Examples are provided for STM32F439 and STM32F479.

Here again you need to adapt examples to your target.

Best regards
