The private key is unique and generated once per device. And it is stored in secure memory and only accessible by CAAM. Therefore, the public key generation and signature functions are the only functions available for the user.
Command usage: mfgprot 0 - prints out the public key for the device. mfgprot 1 - signs and prints out a sample data.
This is only a working example for the signature function, and is intended to be used as a canvas for user-specific cases.
