(Buffer if any to be a multiple of 8 bytes)
CBC-MAC (4 bytes, use MAC variant of MSR DUKPT key)
3.3.2.2 SRED ARQC Request
Begin with a two-byte header in big-endian form (MSB first) that contains the expected length of the
message after decryption, excluding data padding and CBC-MAC. Use container F9 for the MAC
structure, use container F8 within container FA for passing the encrypted ARQC message, and use the
MAC variant of the MSR DUKPT key.
