Change Details

Parent D490 Add PowerPC crypto acceleration support for SHA2. There is also a Power assembly version available for <= POWER 7, but it was not ported. I am getting ~10% improovement on sha256 and 40% improovement on sha512. Before: SHA512 7230ms 7240ms SHA256 8700ms 8690ms After: SHA512 4910ms 5430ms SHA256 7860ms 7860ms commit d0ac1f08e885dd6db68df6771009573c0aceb687 Author: Shawn Landden <shawn@git.icu> Date: Wed May 22 21:36:11 2019 -0300 Support for PowerPC's AES acceleration. This generates the S-Boxes on the fly, and thus is more resistant to side-channel attacks. I get an approximentally 2-3X speed-up with vcrypto support. However, I saw no benifits from additionally using assembly for the block mode code, so it is disabled for adding unnecessary complexity and code size. Fixes T4529
