A fast and independent hashing library pure JavaScript implemented (ES3 compliant) for both server and client side (MD5, SHA1, SHA256, SHA512, RIPEMD, HMAC and Base64)
A fast and independent hashing library pure JavaScript implemented for both server and client side
jsHashes is a pure JavaScript implementation of the most extended hash algorithms.
Its goal is to provide an independent, fast and easy solution for hash algorithms both for client-side and server-side JavaScript environments.
The code is fully compatible with the ECMAScript language specification version 3 and was tested in all major browsers (client-side) and node.js (server-side).
If you are looking for a high low-level performance on the server-side, note that Node.js provides its own C++ native module (Crypto).
MD5 (http://www.ietf.org/rfc/rfc1321.txt)SHA1 (http://www.itl.nist.gov/fipspubs/fip180-1.htm)SHA256 (http://csrc.nist.gov/publications/fips/fips180-2/fips180-2.pdf)SHA512 (http://csrc.nist.gov/publications/fips/fips180-2/fips180-2.pdf)HMAC (http://www.ietf.org/rfc/rfc2104.txt)RIPEMD-160 (http://homes.esat.kuleuven.be/~bosselae/ripemd160.html)Aditional functionalities
Base64 encoding/decoding (http://tools.ietf.org/html/rfc3548)CRC-32 calculationUTF-8 encoding/decodingFollowing some software design patterns, jsHashes implements an object-oriented class-based paradigm for an easy and clean use.
Each algorithm has its respective own class, providing encapsulation and low coupling between classes.
Here you can see an example of how to create a new instance for each algorithm:
// new MD5 instance
var MD5 = new Hashes.MD5;
// new SHA1 instance
var SHA1 = new Hashes.SHA1;
// new SHA256 instance
var SHA256 = new Hashes.SHA256;
// new SHA512 instace
var SHA512 = new Hashes.SHA512;
// new RIPEMD-160 instace
var RMD160 = new Hashes.RMD160;
Now, an example of how to output an hexadecimal-based hash encoding for each algorithm (client-side):
// sample string
var str = 'Sample text!';
// output to console
console.log('MD5: ' + MD5.hex(str));
console.log('SHA1: ' + SHA1.hex(str));
console.log('SHA256: ' + SHA256.hex(str));
console.log('SHA512: ' + SHA512.hex(str));
console.log('RIPEMD-160: ' + RMD160.hex(str));
This is a simple implementation for a client-side environment:
<html>
<head>
<script type="text/javascript" src="src/hashes.js"></script>
<script type="text/javascript">
// sample string
var str = 'This is a sample text!';
// new MD5 instance and hexadecimal string encoding
var MD5 = new Hashes.MD5().hex(str);
// output into DOM
document.write('<p>MD5: <b>' + MD5 + '</b></p>');
</script>
</head>
<body>
</body>
</html>
The library is based on CommonJS module standard, so the same code works in Node and other environments.
jsHashes is available via NPM. You can install it simply doing:
$ npm install jshashes
Additionally, you can get jsHashes using Bower or Jam package managers.
$ bower install jshashes
$ jam install jshashes
A Node.js example:
// require the module
var Hashes = require('jshashes');
// sample string
var str = 'This is a sample text!';
// new SHA1 instance and base64 string encoding
var SHA1 = new Hashes.SHA1().b64(str);
// output to console
console.log('SHA1: ' + SHA1);
Each algorithm class provides the following public methods:
hex(string) - Hexadecimal hash encoding from string.b64(string) - Base64 hash encondig from string.any(string,encoding) - Custom hash algorithm values encoding.hex_hmac(key,string) - Hexadecimal hash with HMAC salt key.b64_hmac(key,string) - Base64 hash with HMAC salt key.any_hmac(key,string,encoding) - Custom hash values encoding with HMAC salt key support.vm_test() - Simple self-test to see is working. Returns this Object.setUpperCase(boolean) - Enable/disable uppercase hexadecimal returned string. Returns this Object.setPad(string) - Defines a custom base64 pad string. Default is '=' according with the RFC standard. Returns this Object.setUTF8(boolean) - Enable/disable UTF-8 character encoding. Returns this Object.any() methodNode.js 0.6.18 running on a VPS Intel I7 930 with 512 MB of RAM (see server/benchmark.js)
