#Description

JavaScript MD5 implementation.
Compatible with server-side environments like Node.js, module loaders like RequireJS or webpack and all web browsers.

#Usage

#Client-side

Install the blueimp-md5 package with NPM:

npm install blueimp-md5

Include the (minified) JavaScript MD5 script in your HTML markup:

<script src="js/md5.min.js"></script>

In your application code, calculate the (hex-encoded) MD5 hash of a string by calling the md5 method with the string as argument:

var hash = md5('value') // "2063c1608d6e0baf80249c42e2be5804"

#Server-side

The following is an example how to use the JavaScript MD5 module on the server-side with Node.js.

Install the blueimp-md5 package with NPM:

npm install blueimp-md5

Add a file server.js with the following content:

require('http')
  .createServer(function (req, res) {
    // The md5 module exports the md5() function:
    var md5 = require('./md5'),
      // Use the following version if you installed the package with npm:
      // var md5 = require("blueimp-md5"),
      url = require('url'),
      query = url.parse(req.url).query
    res.writeHead(200, { 'Content-Type': 'text/plain' })
    // Calculate and print the MD5 hash of the url query:
    res.end(md5(query))
  })
  .listen(8080, 'localhost')
console.log('Server running at http://localhost:8080/')

Run the application with the following command:

node server.js

#Requirements

The JavaScript MD5 script has zero dependencies.

#API

Calculate the (hex-encoded) MD5 hash of a given string value:

var hash = md5('value') // "2063c1608d6e0baf80249c42e2be5804"

Calculate the (hex-encoded) HMAC-MD5 hash of a given string value and key:

var hash = md5('value', 'key') // "01433efd5f16327ea4b31144572c67f6"

Calculate the raw MD5 hash of a given string value:

var hash = md5('value', null, true)

Calculate the raw HMAC-MD5 hash of a given string value and key:

var hash = md5('value', 'key', true)

#Tests

The JavaScript MD5 project comes with Unit Tests.
There are two different ways to run the tests:

• Open test/index.html in your browser or
• run npm test in the Terminal in the root path of the repository package.

The first one tests the browser integration, the second one the Node.js integration.

#License

The JavaScript MD5 script is released under the MIT license.
