  792. Twofish cipher algorithm (x86_64/AVX).
  793. Twofish was submitted as an AES (Advanced Encryption Standard)
  794. candidate cipher by researchers at CounterPane Systems. It is a
  795. 16 round block cipher supporting key sizes of 128, 192, and 256
  796. bits.
  797. This module provides the Twofish cipher algorithm that processes
  798. eight blocks parallel using the AVX Instruction Set.
