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