922 This is a generic implementation of AES that attempts to eliminate
923 data dependent latencies as much as possible without affecting
924 performance too much. It is intended for use by the generic CCM
925 and GCM drivers, and other CTR or CMAC/XCBC based modes that rely
926 solely on encryption (although decryption is supported as well, but
927 with a more dramatic performance hit)
929 Instead of using 16 lookup tables of 1 KB each, (8 for encryption and
930 8 for decryption), this implementation only uses just two S-boxes of
931 256 bytes each, and attempts to eliminate data dependent latencies by
932 prefetching the entire table into the cache at the start of each
933 block. Interrupts are also disabled to avoid races where cachelines
934 are evicted when the CPU is interrupted to do something else.

1582 16 round block cipher supporting key sizes of 128, 192, and 256
1585 This module provides the Twofish cipher algorithm that processes
1586 eight blocks parallel using the AVX Instruction Set.

1600 This is the Deflate algorithm (RFC1951), specified for use in
1601 IPSec with the IPCOMP protocol (RFC3173, RFC2394).
1603 You will most probably want this if using IPSec.

1692 The Jitterentropy RNG is a noise that is intended
1693 to provide seed to another RNG. The RNG does not
1694 perform any cryptographic whitening of the generated
1695 random numbers. This Jitterentropy RNG registers with
1696 the kernel crypto API and can be used by any caller.
