921 This is a generic implementation of AES that attempts to eliminate
922 data dependent latencies as much as possible without affecting
923 performance too much. It is intended for use by the generic CCM
924 and GCM drivers, and other CTR or CMAC/XCBC based modes that rely
925 solely on encryption (although decryption is supported as well, but
926 with a more dramatic performance hit)
928 Instead of using 16 lookup tables of 1 KB each, (8 for encryption and
929 8 for decryption), this implementation only uses just two S-boxes of
930 256 bytes each, and attempts to eliminate data dependent latencies by
