stm32u5 aes cbc 192 bits

[EMont.1]

Hello,

I need to implement AES-CBC 192 bits on micro STM32U5 serie, but hardware only supports 128 or 256 bits 

If i use XCUBE-SAFEA1, ST_Cryptolib is not available for U5 serie.

How can i fix this issue?

Hello @EMont.1 

One possible solution would be to use latest crypto lib V4.1 that supports STM32U5 just to address AES 192 

Best regards
