JavaScript MD5
Contents
Demo
Description
JavaScript MD5 implementation. Compatible with server-side environments like
Node.js, module loaders like RequireJS, Browserify or webpack and all web
browsers.
Usage
Client-side
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.
Create a new directory and add the md5.js file. Or alternatively, 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 testin the Terminal in the root path of the repository package.
The first one tests the browser integration, the second one the
node.js integration.
