In Linux kernel CAAM can be accessed with the help of /dev/cyrpto interface to encrypt/decrypt data. as mentioned in document i.MX Linux User's Guide (IMXLUG) document section 9. Security.
using following API,
echo "OpenSSL" | openssl enc -aes-256-cbc -engine cryptodev > openssl1.dat
openssl enc -aes-256-cbc -d -in openssal.dat
Does this encryption decryption mechanism involves hardware keys like OTPMK or software keys like ZMK?
if yes, how can we verify it?
if no, Is there any way to use these key (directly /indirectly ) for user level encryption.
Thanks in advance;
