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: Adam Langley <agl@golang.org> |

The Go Programming Language
Go is an open source programming language that makes it easy to build simple, reliable, and efficient software.

Our canonical Git repository is located at https://go.googlesource.com/go. There is a mirror of the repository at https://github.com/golang/go.
Please report issues here: https://golang.org/issue/new
Go is the work of hundreds of contributors. We appreciate your help!

Binary Distribution Notes
If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this file). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install-source.html). You should also add the Go binary directory $GOROOT/bin to your shell's path.
For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile:
export GOROOT=$HOME/go
export PATH=$PATH:$GOROOT/bin
See https://golang.org/doc/install or doc/install.html for more details.
