1564           Twofish was submitted as an AES (Advanced Encryption Standard)
1565           candidate cipher by researchers at CounterPane Systems.  It is a
1566           16 round block cipher supporting key sizes of 128, 192, and 256
1567           bits.
1568
1569           This module provides Twofish cipher algorithm that processes three
1570           blocks parallel, utilizing resources of out-of-order CPUs better.
