In linux kernel since version 3.1 (release Date: 2011-10-24)  
Twofish cipher algorithm (x86_64/AVX2).

Twofish was submitted as an AES (Advanced Encryption Standard)
candidate cipher by researchers at CounterPane Systems. It is a
16 round block cipher supporting key sizes of 128, 192, and 256
bits.
