This patch adds crc32 algorithms to shash crypto api. One is wrapper to gerneric crc32_le function. Second is crc32 pclmulqdq implementation. It use hardware provided PCLMULQDQ instruction to accelerate the CRC32 disposal. This instruction present from Intel Westmere and AMD Bulldozer CPUs. For intel core i5 I got 450MB/s for table implementation and 2100MB/s for pclmulqdq implementation.

TEA cipher algorithm.
|
|
|
|
Tiny Encryption Algorithm is a simple cipher that uses
|
|
many rounds for security. It is very fast and uses
|
|
little memory.
|
|
|
|
Xtendend Tiny Encryption Algorithm is a modification to
|
|
the TEA algorithm to address a potential key weakness
|
|
in the TEA algorithm.
|
|
|
|
Xtendend Encryption Tiny Algorithm is a mis-implementation
|
|
of the XTEA algorithm for compatibility purposes.
