Hi,

i'm using mmCAU API on K64 mcu and i have some questions about the AES key storage.

1) If i set key using cau_aes_set_key can i assume that the key will be inaccessible to read-back?

2) The key is stored in a non-volatile memory area? Can i program the key in production-phase and use it without set it any time i reset, power-off and power-on and so on?

 

Thank you and regards.
