# Contributing to Go
Go is an open source project.
It is the work of hundreds of contributors. We appreciate your help!
## Filing issues
When [filing an issue](https://golang.org/issue/new), make sure to answer these five questions:
1. What version of Go are you using (`go version`)?
2. What operating system and processor architecture are you using?
3. What did you do?
4. What did you expect to see?
5. What did you see instead?
General questions should go to the [golang-nuts mailing list](https://groups.google.com/group/golang-nuts) instead of the issue tracker.
The gophers there will answer or ask you to file an issue if you've tripped over a bug.
## Contributing code
Please read the [Contribution Guidelines](https://golang.org/doc/contribute.html)
before sending patches.
**We do not accept GitHub pull requests**
(we use [Gerrit](https://code.google.com/p/gerrit/) instead for code review).
Unless otherwise noted, the Go source files are distributed under
the BSD-style license found in the LICENSE file.

# Go Cryptography
This repository holds supplementary Go cryptography libraries.
## Download/Install
The easiest way to install is to run `go get -u golang.org/x/crypto/...`. You
can also manually git clone the repository to `$GOPATH/src/golang.org/x/crypto`.
## Report Issues / Send Patches
This repository uses Gerrit for code changes. To learn how to submit changes to
this repository, see https://golang.org/doc/contribute.html.
The main issue tracker for the crypto repository is located at
https://github.com/golang/go/issues. Prefix your issue with "x/crypto:" in the
subject line, so it is easy to find.
Note that contributions to the cryptography package receive additional scrutiny
due to their sensitive nature. Patches may take longer than normal to receive
feedback.

// Package bn256 implements a particular bilinear group at the 128-bit security level.
//
// Bilinear groups are the basis of many of the new cryptographic protocols
// that have been proposed over the past decade. They consist of a triplet of
// groups (G₁, G₂ and GT) such that there exists a function e(g₁ˣ,g₂ʸ)=gTˣʸ
// (where gₓ is a generator of the respective group). That function is called
// a pairing function.
//
// This package specifically implements the Optimal Ate pairing over a 256-bit
// Barreto-Naehrig curve as described in
// http://cryptojedi.org/papers/dclxvi-20100714.pdf. Its output is compatible
// with the implementation described in that paper.
