# js-sha3

[![Build Status](https://travis-ci.org/emn178/js-sha3.svg?branch=master)](https://travis-ci.org/emn178/js-sha3)
[![Coverage Status](https://coveralls.io/repos/emn178/js-sha3/badge.svg?branch=master)](https://coveralls.io/r/emn178/js-sha3?branch=master)  
[![NPM](https://nodei.co/npm/js-sha3.png?stars&downloads)](https://nodei.co/npm/js-sha3/)

A simple SHA-3 / Keccak / Shake hash function for JavaScript supports UTF-8 encoding.

## Notice
* v0.8.0+ will throw an error if try to update hash after finalize.
* Sha3 methods has been renamed to keccak since v0.2.0. It means that sha3 methods of v0.1.x are equal to keccak methods of v0.2.x and later.
* `buffer` method is deprecated. This maybe confuse with Buffer in node.js. Please use `arrayBuffer` instead.

## Installation
You can also install js-sha3 by using Bower.

    bower install js-sha3

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

    npm install js-sha3

## Usage
You could use like this:
```JavaScript
sha3_512('Message to hash');
sha3_384('Message to hash');
sha3_256('Message to hash');
sha3_224('Message to hash');
keccak512('Message to hash');
keccak384('Message to hash');
keccak256('Message to hash');
keccak224('Message to hash');
shake128('Message to hash', 256);
shake256('Message to hash', 512);
cshake128('Message to hash', 256, 'function name', 'customization');
cshake256('Message to hash', 512, 'function name', 'customization');
kmac128('key', 'Message to hash', 256, 'customization');
kmac256('key', 'Message to hash', 512, 'customization');

// Support ArrayBuffer output
var arrayBuffer = keccak224.arrayBuffer('Message to hash');

// Support Array output
var bytes = keccak224.digest('Message to hash');
var bytes = keccak224.array('Message to hash');

// update hash
sha3_512.update('Message ').update('to ').update('hash').hex();
// specify shake output bits at first update
shake128.update('Message ', 256).update('to ').update('hash').hex();

// or to use create
var hash = sha3_512.create();
hash.update('...');
hash.update('...');
hash.hex();

// specify shake output bits when creating
var hash = shake128.create(256);
hash.update('...');
hash.update('...');
hash.hex();

// specify cshake output bits, function name and customization when creating
var hash = cshake128.create(256, 'function name', 'customization');

// specify kmac key, output bits and customization when creating
var hash = kmac128.create('key', 256, 'customization');
```
If you use node.js, you should require the module first:
```JavaScript
sha3_512 = require('js-sha3').sha3_512;
sha3_384 = require('js-sha3').sha3_384;
sha3_256 = require('js-sha3').sha3_256;
sha3_224 = require('js-sha3').sha3_224;
keccak512 = require('js-sha3').keccak512;
keccak384 = require('js-sha3').keccak384;
keccak256 = require('js-sha3').keccak256;
keccak224 = require('js-sha3').keccak224;
shake128 = require('js-sha3').shake128;
shake256 = require('js-sha3').shake256;
cshake128 = require('js-sha3').cshake128;
cshake256 = require('js-sha3').cshake256;
kmac128 = require('js-sha3').kmac128;
kmac256 = require('js-sha3').kmac256;
```
If you use TypeScript, you can import like this:
```TypeScript
import { sha3_512 } from 'js-sha3';
```

```JavaScript
