[PATCH 00/18] crypto: Add helper functions for parallelized LRW and XTS modes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This series adds lrw_crypt() and xts_crypt() functions for cipher implementations that
can benefit from parallel cipher block operations. To make interface flexible, 
caller is reponsible of allocating buffer large enough to store temporary cipher
blocks. This buffer size should be as large as size of parallel blocks processed at
once. Cryption callback is called with buffer size at maximum of parallel blocks size
and at minimum size of one block.

Series adds LRW/XTS support to serpent-sse2 and twofish-x86_64-3way, and therefore
depends on those series.

Patches 1-4: include LRW fixes/cleanups, export gf128mul table and add lrw_crypt().
Patches 5-7: add LRW support to serpent-sse2, with tcrypt tests and test vectors.
Patches 8-10: add LRW support to twofish-x86_64-3way, with tcrypt tests and test vectors.
Patches 11-12: include XTS cleanup for blocksize usage and add xts_crypt().
Patches 13-15: add XTS support to serpent-sse2, with tcrypt tests and test vectors.
Patches 16-18: add XTS support to twofish-x86_64-3way, with tcrypt tests and test vectors.
