| 19 | # This is AESNI-CBC+SHA256 stitch implementation. The idea, as spelled | |
| 20 | # in http://download.intel.com/design/intarch/papers/323686.pdf, is | |
| 21 | # that since AESNI-CBC encrypt exhibit *very* low instruction-level | |
| 22 | # parallelism, interleaving it with another algorithm would allow to | |
| 23 | # utilize processor resources better and achieve better performance. | |
| 24 | # SHA256 instruction sequences(*) are taken from sha512-x86_64.pl and | |
| 25 | # AESNI code is weaved into it. As SHA256 dominates execution time, | |
| 26 | # stitch performance does not depend on AES key length. Below are | |
| 27 | # performance numbers in cycles per processed byte, less is better, | |
| 28 | # for standalone AESNI-CBC encrypt, standalone SHA256, and stitched | |
| 29 | # subroutine: | |
