[](https://github.com/feross/standard)
-JavaScript component to compute the RIPEMD-160 hash of strings or bytes. This hash is commonly used in crypto currencies
-like Bitcoin.
+Node style `ripemd160` on pure JavaScript.
-Usage
------
-
-### Install
-
- npm install --save ripemd160
-
-
-### ripemd160(input)
-
-`input` should be either a `string`, `Buffer`, or an `Array`. It returns a `Buffer`.
-
-**example 1**:
-
-```js
-var ripemd16 = require('ripemd160')
-
-var data = 'hello'
-var result = ripemd160(data)
-console.log(result.toString('hex'))
-// => 108f07b8382412612c048d07d13f814118445acd
-```
-
-**example 2**:
-
-```js
-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](http://browserify.org/) environment. Converting to and from Buffers is very easy.
-
-##### To buffer
-
-```js
-// 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
+## Example
```js
-// to string
-var str = buf.toString('utf8')
+var RIPEMD160 = require('ripemd160')
-// to hex string
-var hex = buf.toString('hex')
+console.log(new RIPEMD160().update('42').digest('hex'))
+// => 0df020ba32aa9b8b904471ff582ce6b579bf8bc8
-// to array
-var arr = [].slice.call(buf)
+var ripemd160stream = new RIPEMD160()
+ripemd160stream.end('42')
+console.log(ripemd160stream.read().toString('hex'))
+// => 0df020ba32aa9b8b904471ff582ce6b579bf8bc8
