The AES algorithm is specified in [FIPS197] . AES encrypts and decrypts data in 128-bit blocks, using 128-, 192- or 256-bit keys. The nomenclature for AES for the different key sizes is AES- x , where x is the key size (e.g., AES-256).
3 Sometimes a key pair is generated by a party that is trusted by the key owner.
