RE: U-BOOT missing Security support

15 Sep 2021


      Thank you
My only question now is how do I set the AES key I though this would be an option in kconfig as well or is this an option for the command itself?

I was attempting to enable CONFIG_CMD_AES and I though it would be

be enabled or available?
Search under "Security commands"...
from "cmd/Kconfig":
....
1975 menu "Security commands"
1976 config CMD_AES
1977         bool "Enable the 'aes' command"
1978         select AES
1979         help
1980           This provides a means to encrypt and decrypt data using the AES
1981           (Advanced Encryption Standard). This algorithm uses a symetric key
1982           and is widely used as a streaming cipher. Different key lengths are
1983           supported by the algorithm but this command only supports 128 bits
1984           at present.
