1577           Twofish cipher algorithm (x86_64/AVX).
1578
1579           Twofish was submitted as an AES (Advanced Encryption Standard)
1580           candidate cipher by researchers at CounterPane Systems.  It is a
1581           16 round block cipher supporting key sizes of 128, 192, and 256
1582           bits.
1583
1584           This module provides the Twofish cipher algorithm that processes
1585           eight blocks parallel using the AVX Instruction Set.
