Check in an initial implementation of CBC-MAC.
The test vectors were generated by Crypto++ 5.5 on a Linux/x86-64 machine. Test vectors for CBC-MAC(DES) all pass, for inputs up to 63 bytes. For CBC-MAC(AES-128), all test vectors with inputs over 10 bytes fail to verify against what Crypto++ produces. Unknown at this time where the bug lies.
