Overview
--------

The primary goal of this project is to produce a translation of TweetNaCl to
JavaScript which is as close as possible to the original C implementation, plus
a thin layer of idiomatic high-level API on top of it.

There are two versions, you can use either of them:

* `nacl.js` is the port of TweetNaCl with minimum differences from the
  original + high-level API.

* `nacl-fast.js` is like `nacl.js`, but with some functions replaced with
  faster versions.


Installation
------------

You can install TweetNaCl.js via a package manager:

[Bower](http://bower.io):

    $ bower install tweetnacl
