jshashes is lightweight library implementing the most extended cryptographic hash function algorithms in pure JavaScript (ES5 compliant).
The goal is to provide an dependency-free, fast and reliable solution for hash algorithms for both client-side and server-side JavaScript environments. The code is fully compatible with the ECMAScript 5 specification and is used in production in browsers and node.js/io.js
If you are looking for a low-level performance library for the server-side, note that node.js/io.js provides its own 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)

- Browsers (ES3)
- node.js/io.js (all versions)
- Rhino
- RingoJS
Each algorithm has its respective own instantiable object. Here you can see an example of how to create a new instance for each one:
// 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.RMD160An example of how to generate an hexadecimal-based hash encoding for each algorithm:
// 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>// 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)You can use the simple command-line interface to generate hashes.
$ hashes sha1-hex This is a sample string
> b6a8501d8a70e74e1dc12a6082102622fdc719bb
# or with quotes
$ hashes sha1-hex "This is a sample string"
> b6a8501d8a70e74e1dc12a6082102622fdc719bbFor more information about the options supported, type:
$ hashes -hVia npm
$ npm install jshashes
Via Bower:
$ bower install jshashes
Via Component:
$ component install h2non/jshashes

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. ReturnsthisObject.setUpperCase(boolean)- Enable/disable uppercase hexadecimal returned string. ReturnsthisObject.setPad(string)- Defines a custom base64 pad string. Default is '=' according with the RFC standard. ReturnsthisObject.setUTF8(boolean)- Enable/disable UTF-8 character encoding. ReturnsthisObject.
- Hexadecimal (most extended)
- Base64
- Custom hash values

- Don't support checksum hash for files on the server-side, only strings-based inputs are supported.
- It has not been planned to include support for more hash algorithms.
- The goal is to provide the same JavaScript code in both server and client side, so it isn't planned to improve it in other ways.
- Only Node.js server-side was tested, so with minimal changes, you can setup
jsHashesin other server-side JS environment.
