+# MD5
+
+[![build status](https://secure.travis-ci.org/pvorb/node-md5.png)](http://travis-ci.org/pvorb/node-md5) [![info badge](https://img.shields.io/npm/dt/md5.svg)](http://npm-stat.com/charts.html?package=md5)
+
+a JavaScript function for hashing messages with MD5.
+
+node-md5 is being sponsored by the following tool; please help to support us by taking a look and signing up to a free trial  
+<a href="https://tracking.gitads.io/?repo=node-md5"><img src="https://images.gitads.io/node-md5" alt="GitAds"/></a>
+
+## Installation
+
+You can use this package on the server side as well as the client side.
+
+### [Node.js](http://nodejs.org/):
+
+~~~
+npm install md5
+~~~
+
+
+## API
+
+~~~ javascript
+md5(message)
+~~~
+
+  * `message` -- `String`, `Buffer`, `Array` or `Uint8Array`
+  * returns `String`
+
+
+## Usage
+
+~~~ javascript
+var md5 = require('md5');
+
+console.log(md5('message'));
+~~~
+
+This will print the following
+
+~~~
+78e731027d8fd50ed642340b7c9a63b3
+~~~
+
+It supports buffers, too
+
+~~~ javascript
+var fs = require('fs');
+var md5 = require('md5');
+
+fs.readFile('example.txt', function(err, buf) {
+  console.log(md5(buf));
+});
+~~~
+
+## Versions
+
+Before version 2.0.0 there were two packages called md5 on npm, one lowercase,
+one uppercase (the one you're looking at). As of version 2.0.0, all new versions
+of this module will go to lowercase [md5](https://www.npmjs.com/package/md5) on
+npm. To use the correct version, users of this module will have to change their
+code from `require('MD5')` to `require('md5')` if they want to use versions >=
+2.0.0.
+
+
+## Bugs and Issues
+
+If you encounter any bugs or issues, feel free to open an issue at
+[github](https://github.com/pvorb/node-md5/issues).
+
+
+## Credits
+
+This package is based on the work of Jeff Mott, who did a pure JS implementation
+of the MD5 algorithm that was published by Ronald L. Rivest in 1991. I needed a
+npm package of the algorithm, so I used Jeff’s implementation for this package.
+The original implementation can be found in the
+[CryptoJS](http://code.google.com/p/crypto-js/) project.
