Now that we have a constant-time P-256 implementation, it's worth paying more attention elsewhere. The inversion of k in (EC)DSA was using Euclid's algorithm which isn't constant-time. This change switches to Fermat's algorithm, which is much better. However, it's important to note that math/big itself isn't constant time and is using a 4-bit window for exponentiation with variable memory access patterns. (Since math/big depends quite deeply on its values being in minimal (as opposed to fixed-length) represetation, perhaps crypto/elliptic should grow a constant-time implementation of exponentiation in the scalar field.)

README
This is the source code repository for the Go programming language.
For documentation about how to install and use Go,
visit http://golang.org/ or load doc/install-source.html
in your web browser.
After installing Go, you can view a nicely formatted
doc/install-source.html by running godoc --http=:6060
and then visiting http://localhost:6060/doc/install/source.
Unless otherwise noted, the Go source files are distributed
under the BSD-style license found in the LICENSE file.

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 README). 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.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 doc/install.html for more details.
