916 Rijndael appears to be consistently a very good performer in

918 environments regardless of its use in feedback or non-feedback
919 modes. Its key setup time is excellent, and its key agility is

936 and GCM drivers, and other CTR or CMAC/XCBC based modes that rely
937 solely on encryption (although decryption is supported as well, but
938 with a more dramatic performance hit)
940 Instead of using 16 lookup tables of 1 KB each, (8 for encryption and
941 8 for decryption), this implementation only uses just two S-boxes of
942 256 bytes each, and attempts to eliminate data dependent latencies by

1588 Twofish cipher algorithm (x86_64/AVX).
1590 Twofish was submitted as an AES (Advanced Encryption Standard)
1591 candidate cipher by researchers at CounterPane Systems. It is a
1592 16 round block cipher supporting key sizes of 128, 192, and 256
1595 This module provides the Twofish cipher algorithm that processes
1596 eight blocks parallel using the AVX Instruction Set.

1610 This is the Deflate algorithm (RFC1951), specified for use in
1611 IPSec with the IPCOMP protocol (RFC3173, RFC2394).
1613 You will most probably want this if using IPSec.
