From deb8af6eb71f9ad951137ee6e84e971c3ab23ec4 Mon Sep 17 00:00:00 2001 From: Damjan Marion Date: Tue, 2 Apr 2019 19:06:50 +0200 Subject: Add crypto_ia32 plugin Currently this plugin provies AES CBC optimized code. Encryption code supports parallel encryption of 4 buffers with different size and key which improves performance 4x compared to standard serialized aproach. On Skylake Server measured performance is around 0.71 clocks/byte with 256 buffers with size in range between 7000 and 8000 bytes. Measured performance includes overhead of processing crypto ops.
