I am using multiple MCUs: STM32F733, STM32L433, STM32L443.
In STM32CubeExpansion_Crypto_V3.1.0 I am using the software AES CTR encryption (Inc/AES/CTR/aes_ctr.h). I use AES_CTR_Encrypt_Init / AES_CTR_Encrypt_Append / AES_CTR_Encrypt_Finish methods. This works fine, though I would like to use the hardware AES for the MCU having it (F733, L443).
I did not find a CTR related file in the STM32_Crypto_AccHw folder or some AccHw_AES_CTR_Encrypt* methods.
Is there a way to use the HW acceleration for AES CTR more ?
