1564
1565           Twofish was submitted as an AES (Advanced Encryption Standard)
1566           candidate cipher by researchers at CounterPane Systems.  It is a
1567           16 round block cipher supporting key sizes of 128, 192, and 256
1568           bits.
1569
1570           This module provides Twofish cipher algorithm that processes three
1571           blocks parallel, utilizing resources of out-of-order CPUs better.
