The existing implementation didn't use the CLMUL instructions for fast and constant time binary-field multiplication. With this change, amd64 CPUs that support both AES and CLMUL instructions will use an optimised asm implementation. benchmark old ns/op new ns/op delta BenchmarkAESGCMSeal8K 91723 3200 -96.51% BenchmarkAESGCMOpen8K 91487 3324 -96.37% BenchmarkAESGCMSeal1K 11873 546 -95.40% BenchmarkAESGCMOpen1K 11833 594 -94.98% benchmark old MB/s new MB/s speedup BenchmarkAESGCMSeal8K 89.31 2559.62 28.66x BenchmarkAESGCMOpen8K 89.54 2463.78 27.52x BenchmarkAESGCMSeal1K 86.24 1872.49 21.71x BenchmarkAESGCMOpen1K 86.53 1721.78 19.90x Change-Id: Idd63233098356d8b353d16624747b74d0c3f193e Reviewed-on: https://go-review.googlesource.com/10484 TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by:
