how to enable hardware cryptography for nucleo-u575zi_q / nucleo-u585ai board?

[aR.1]

Hi,

I am working on enabling hardware cryptography in nucleo-u585ai board.

Can you suggest an example for enabling hardware cryptography? or Is it enabled always?

How to test or know that data is encrypted?

Thanks,

Check if there are code examples for the EVAL series board, port those to the NUCLEO.

Have some examples and test cases / patterns you construct on a PC, or other platform, and compare results. Create encrypt and decrypt test code and have them communicate and validate results.

​

E​xpect to have to understand the concepts and methods.

Thanks for the reply

I would like to know whether the hardware cryptography feature is enabled implicitly or we need to enable it?

We are using zephyr rtos . Is hardware cryptography enable and disable is present in zephyr?

It is a synchronous peripheral, expect you'll need to enable the clocks like you would on any other peripheral.

There's surely some coverage and description in the Reference Manual

STM32Cube_FW_U5_V1.1.1\Projects\B-U585I-IOT02A\Examples\CRYP\CRYP_AES_GCM

Support in an OS would depend on appropriate drivers. The hardware isn't multi-threaded or multi-context, so you'd have to arbitrate usage.
