# jsHashes [![Build Status](https://travis-ci.org/h2non/jshashes.svg)](https://travis-ci.org/h2non/jshashes) [![NPM version](https://img.shields.io/npm/v/jshashes.svg)](https://www.npmjs.com/package/jshashes) `jshashes` is lightweight library implementing the most extended [cryptographic hash function](http://en.wikipedia.org/wiki/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](http://nodejs.org)/[io.js](http://iojs.org) 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`](http://nodejs.org/api/crypto.html) ## Supported hash algorithms * `MD5` () * `SHA1` () * `SHA256` () * `SHA512` () * `HMAC` () * `RIPEMD-160` () **Aditional functionalities** * `Base64 encoding/decoding` () * `CRC-32 calculation` * `UTF-8 encoding/decoding` ## Environments - Browsers (ES3) - node.js/io.js (all versions) - Rhino - RingoJS ## Usage Each algorithm has its respective own instantiable `object`. Here you can see an example of how to create a new instance for each one: ```javascript // 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 ``` An example of how to generate an hexadecimal-based hash encoding for each algorithm: ```javascript // 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)) ``` ### Browsers This is a simple implementation for a client-side environment: ```html ``` ### node.js / io.js ```javascript // 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) ``` ### Command-line interface You can use the simple command-line interface to generate hashes. ```bash $ hashes sha1-hex This is a sample string > b6a8501d8a70e74e1dc12a6082102622fdc719bb # or with quotes $ hashes sha1-hex "This is a sample string" > b6a8501d8a70e74e1dc12a6082102622fdc719bb ``` For more information about the options supported, type: ```bash $ hashes -h ``` ### Installation Via [npm](https://npmjs.org) ``` $ npm install jshashes ``` Via [Bower](http://bower.io/): ``` $ bower install jshashes ``` Via [Component](https://github.com/component/component): ``` $ component install h2non/jshashes ``` Or loading the script directly: ``` http://cdn.rawgit.com/h2non/jsHashes/master/hashes.js ``` ## Public methods 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. ## Hash encoding formats supported * Hexadecimal (most extended) * Base64 * Custom hash values `any()` method ## Benchmark Node.js 0.6.18 running on a VPS Intel I7 930 with 512 MB of RAM (see `server/benchmark.js`) ```javascript Simple benchmark test generating 10000 hashes for each algorithm.

(gh #6) - New test suite for hashes, CRC32, and hmac; run with 'npm test' in node. - Fixed global variable leaks. (gh #13) - CRC32 will now always return positive values. (gh #11) - Added package version property to the exposed Hashes Object - Updated CLI script utility supporting all algorithms (see bin/hashes) - Fixed UTF-8 encoding/decoding error (if input parameter is undefined or invalid) * `1.0.2` - Performance improvements and minimal refactor (length property caching, literal notation) - Available from Bower package manager * `1.0.1` - Refactoring (hoisting, coercion, removed redundant functions, scoping, restructure...) - Performance improves - JSLint validation (except bitwise operators) - Now the library can be used like a AMD CommonJS module - Updated documentation - New folders structure - Added closure compiled and minimized library version - Available from Jam package manager * `0.1.5b` - Added index.js for easy call the module in Node.js - Updated documentation * `0.1.4b` - Now declaring objects using Literal Notation. - Solved sintax errors on minimized version (jshashes.min.js) - Added benchmark test and sample * `0.1.3b` - Starting non-redundancy code refactorization - Added `Helpers` Object with some global functions - Added native support for Base64 provided as `class` - Added CRC-32 calculation support - Added URL encode/decode helpers functions * `0.1.2b` - SHA1 error fixed. - General code changes (renaming classes, private methods, new methods...). - Changing library namespace to 'Hashes'. - Starting code documentation. - Added new examples of how to use. * `0.1.1b` - Minimal library improvements. - There has been added some samples, like how to use it and support for NPM package. * `0.1.0b` - First release: the code is stable, but the library is still beta and must be improved and documented. ## TODO * Performance benchmarking ## Authors ### Library author * [Tomas Aparicio](https://github.com/h2non/) ### Original algorithm authors * [Paul Johnston](http://pajhome.org.uk/crypt/md5/) * Angel Marin (SHA256) * Jeremy Lin (RIPEMD-160) ### Other contributors * [C.
