Package Exports

js-sha3

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (js-sha3) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

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

Notice

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.

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:

sha3_512('Message to hash');
sha3_384('Message to hash');
sha3_256('Message to hash');
sha3_224('Message to hash');
keccak_512('Message to hash');
keccak_384('Message to hash');
keccak_256('Message to hash');
keccak_224('Message to hash');

If you use node.js, you should require the module first:

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;
keccak_512 = require('js-sha3').keccak_512;
keccak_384 = require('js-sha3').keccak_384;
keccak_256 = require('js-sha3').keccak_256;
keccak_224 = require('js-sha3').keccak_224;

Extensions

jQuery

If you prefer jQuery style, you can add following code to add a jQuery extension.

Code

jQuery.sha3_512 = sha3_512;
jQuery.sha3_384 = sha3_384;
jQuery.sha3_256 = sha3_256;
jQuery.sha3_224 = sha3_224;
jQuery.keccak_512 = keccak_512;
jQuery.keccak_384 = keccak_384;
jQuery.keccak_256 = keccak_256;
jQuery.keccak_224 = keccak_224;

And then you could use like this:

$.sha3_512('message');
$.sha3_384('message');
$.sha3_256('message');
$.sha3_224('message');
$.keccak_512('message');
$.keccak_384('message');
$.keccak_256('message');
$.keccak_224('message');

Prototype

If you prefer prototype style, you can add following code to add a prototype extension.

Code

String.prototype.sha3_512 = function() {
  return sha3_512(this);
};
String.prototype.sha3_384 = function() {
  return sha3_384(this);
};
String.prototype.sha3_256 = function() {
  return sha3_256(this);
};
String.prototype.sha3_224 = function() {
  return sha3_224(this);
};
String.prototype.keccak_512 = function() {
  return keccak_512(this);
};
String.prototype.keccak_384 = function() {
  return keccak_384(this);
};
String.prototype.keccak_256 = function() {
  return keccak_256(this);
};
String.prototype.keccak_224 = function() {
  return keccak_224(this);
};

And then you could use like this:

'message'.sha3_512();
'message'.sha3_384();
'message'.sha3_256();
'message'.sha3_224();
'message'.keccak_512();
'message'.keccak_384();
'message'.keccak_256();
'message'.keccak_224();
