sha3_384('Message to hash');
sha3_256('Message to hash');
sha3_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;

Example

Code

sha3_512('');
sha3_512('The quick brown fox jumps over the lazy dog');
sha3_512('The quick brown fox jumps over the lazy dog.');
sha3_384('');
sha3_384('The quick brown fox jumps over the lazy dog');
sha3_384('The quick brown fox jumps over the lazy dog.');
sha3_256('');
sha3_256('The quick brown fox jumps over the lazy dog');
sha3_256('The quick brown fox jumps over the lazy dog.');
sha3_224('');
sha3_224('The quick brown fox jumps over the lazy dog');
sha3_224('The quick brown fox jumps over the lazy dog.');

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;

And then you could use like this:

$.sha3_512('message');
$.sha3_384('message');
$.sha3_256('message');
$.sha3_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);
};

And then you could use like this:

'message'.sha3_512();
'message'.sha3_384();
'message'.sha3_256();
'message'.sha3_224();
