1585 Twofish cipher algorithm (x86_64/AVX).
1587 Twofish was submitted as an AES (Advanced Encryption Standard)
1588 candidate cipher by researchers at CounterPane Systems. It is a
1589 16 round block cipher supporting key sizes of 128, 192, and 256
1592 This module provides the Twofish cipher algorithm that processes
1593 eight blocks parallel using the AVX Instruction Set.
