1178 16 round block cipher supporting key sizes of 128, 192, and 256
1179 bits.
1180
1181 This module provides the Twofish cipher algorithm that processes
1182 eight blocks parallel using the AVX Instruction Set.

1195 This is the Deflate algorithm (RFC1951), specified for use in
1196 IPSec with the IPCOMP protocol (RFC3173, RFC2394).
