ripemd160

JavaScript component to compute the RIPEMD-160 hash of strings or bytes. This hash is commonly used in crypto currencies like Bitcoin.

Usage

Install

npm install --save ripemd160

ripemd160(input)

input should be either a string, Buffer, or an Array. It returns a Buffer.

example 1:

var ripemd16 = require('ripemd160')

var data = 'hello'
var result = ripemd160(data)
console.log(result.toString('hex'))
// => 108f07b8382412612c048d07d13f814118445acd

example 2:

var ripemd16 = require('ripemd160')

var data = new Buffer('hello', 'utf8')
var result = ripemd160(data)
console.log(result.toString('hex'))
// => 108f07b8382412612c048d07d13f814118445acd

Converting Buffers

If you're not familiar with the Node.js ecosystem, type Buffer is a common way that a developer can pass around binary data. Buffer also exists in the Browserify environment. Converting to and from Buffers is very easy.

To buffer

// from string
var buf = new Buffer('some string', 'utf8')

// from hex string
var buf = new Buffer('3f5a4c22', 'hex')

// from array
var buf = new Buffer([1, 2, 3, 4])

From buffer

// to string
var str = buf.toString('utf8')

// to hex string
var hex = buf.toString('hex')

// to array
var arr = [].slice.call(buf)

Testing

Install dev deps:

npm install --development

Test in Node.js:

npm run test

Test in a Browser:

Testing in the browser uses the excellent Mochify. Mochify can use either PhantomJS or an actual browser. You must have Selenium installed if you want to use an actual browser. The easiest way is to npm install -g start-selenium and then run start-selenium.

Then run:

npm run browser-test
