U-BOOT missing Security support

U-BOOT missing Security support

Hello,
I was attempting to enable CONFIG_CMD_AES and I though it would be under security support. Is there any reason why that option would not be enabled or available?
Thanks

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.
1985
....

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?
