Secure boot AES Cipher Type

[addisonaudette1]

What AES cipher type does the secure boot implementation for S32k33 boards use?

Hi @addisonaudette1,

HSE includes an AES engine supporting all standard key sizes (128, 192, 256 bits) and various complex ciphering modes (CBC, CTR, GCM, and so on).

You can refer to HSE's reference manual, from secure files inside the S32K3 page: S32K3 Auto General-Purpose MCUs.

Best regards,
Julián
