A simple SHA-512, SHA-384, SHA-512/224, SHA-512/256 hash functions for JavaScript supports UTF-8 encoding.

## Notice
* v0.8.0+ will throw an error if try to update hash after finalize.

## Installation
You can also install js-sha512 by using Bower.

    bower install js-sha512

For node.js, you can use this command to install:

    npm install js-sha512

## Usage
You could use like this:
```JavaScript
sha512('Message to hash');
sha384('Message to hash');
sha512_256('Message to hash');
sha512_224('Message to hash');

// Support ArrayBuffer output
var arrayBuffer = sha512.arrayBuffer('Message to hash');

// Support Array output
var bytes = sha512.digest('Message to hash');
var bytes = sha512.array('Message to hash');

// update hash
var hash = sha512.update('Message to hash');
hash.update('Message2 to hash');
hash.hex();

// or to use create
var hash = sha512.create();
hash.update('Message to hash');
hash.hex();

// clone
var hash = sha512.update('Message to hash');
var hash2 = hash.clone();
hash2.hex();
hash.update('Message2 to hash');
hash.hex();

// HMAC
sha512.hmac('key', 'Message to hash');
sha384.hmac('key', 'Message to hash');

var hash = sha512.hmac.create('key');
hash.update('Message to hash');
hash.hex();

var hash2 = sha512.hmac.update('key', 'Message to hash');
hash2.update('Message2 to hash');
hash2.array();
```
If you use node.js, you should require the module first:
```JavaScript
var sha512 = require('js-sha512');
```
or 
```JavaScript
var sha512 = require('js-sha512').sha512;
var sha384 = require('js-sha512').sha384;
var sha512_256 = require('js-sha512').sha512_256;
var sha512_224 = require('js-sha512').sha512_224;
```
It supports AMD:
```JavaScript
require(['your/path/sha512.js'], function(sha512) {
// ...
});
```
