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, 3-way parallel).
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 Twofish cipher algorithm that processes three
1596 blocks parallel, utilizing resources of out-of-order CPUs better.
