ENCODEKEY128: Wrap a 128-bit AES key to a key handle. ENCODEKEY256: Wrap a 256-bit AES key to a key handle. AESENC128KL: Encrypt a 128-bit block of data using a 128-bit AES key indicated by a key handle. AESENC256KL: Encrypt a 128-bit block of data using a 256-bit AES key indicated by a key handle. AESDEC128KL: Decrypt a 128-bit block of data using a 128-bit AES key indicated by a key handle. AESDEC256KL: Decrypt a 128-bit block of data using a 256-bit AES key indicated by a key handle. AESENCWIDE128KL: Encrypt 8 128-bit blocks of data using a 128-bit AES key indicated by a key handle. AESENCWIDE256KL: Encrypt 8 128-bit blocks of data using a 256-bit AES key indicated by a key handle. AESDECWIDE128KL: Decrypt 8 128-bit blocks of data using a 128-bit AES key indicated by a key handle. AESDECWIDE256KL: Decrypt 8 128-bit blocks of data using a 256-bit AES key indicated by a key handle. Details of these instructions can be found in Intel Software Developer's Manual.
