 923           data dependent latencies as much as possible without affecting
 924           performance too much. It is intended for use by the generic CCM
 925           and GCM drivers, and other CTR or CMAC/XCBC based modes that rely
 926           solely on encryption (although decryption is supported as well, but

 928
 929           Instead of using 16 lookup tables of 1 KB each, (8 for encryption and
 930           8 for decryption), this implementation only uses just two S-boxes of
 931           256 bytes each, and attempts to eliminate data dependent latencies by
 932           prefetching the entire table into the cache at the start of each

1578           Twofish cipher algorithm (x86_64/AVX).
1579
1580           Twofish was submitted as an AES (Advanced Encryption Standard)
1581           candidate cipher by researchers at CounterPane Systems.  It is a
1582           16 round block cipher supporting key sizes of 128, 192, and 256
1583           bits.
1584
1585           This module provides the Twofish cipher algorithm that processes
1586           eight blocks parallel using the AVX Instruction Set.
