Starting Point advice for STM32L451 Cryptographic Peripheral

[EOCon.1]

Hi all,

I would like to use the Cryptographic peripheral in my STM32L451 to encode and decode some data based on a pre-stored common key.

Are there any examples for Atollic that would get me started on this?

Hello @Community member​ ,

I adivse you to refer to the HAL example within STM32CubeL4 firmware and you can easily port it on the STM32L451:

STM32Cube_FW_L4_V1.17.0\Projects\STM32L476G-EVAL\Examples\CRYP

You can also download the STM32CubeExpansion_Crypto_V4.0.1 library, and easily port the STM32L4 example according to your needs.

Hope this helps you!

ok, is there a reason why there is zero mention of CRYP or AES in the file the stores all of the register base addresses?

https://raw.githubusercontent.com/STMicroelectronics/cmsis_device_l4/master/Include/stm32l451xx.h

I have tried to look at some example but in the stm32l4xx_hal_cryp.h file there is this definition AES_TypeDef *Instance; /*!< Register base address */

This definition should be defined in my link along with the register layout but it is not, can you please explain why?

Please show me which file has the register map for the AES peripheral.

Problem solved, my L451 does not have the hardware peripheral,only the big brother of this family
