A simple SHA-256 / SHA-224 hash function for JavaScript supports UTF-8 encoding.

Package Exports

  • js-sha256
  • js-sha256/src/sha256

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-sha256) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Installation

You can also install js-sha256 by using Bower.

bower install js-sha256

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

npm install js-sha256

Usage

You could use like this:

sha256('Message to hash');
sha224('Message to hash');

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

sha256 = require('js-sha256');

or 

sha256 = require('js-sha256').sha256;
sha224 = require('js-sha256').sha224;

Methods

sha256(str, asciiOnly)

Hash string to sha256, set asciiOnly to true for better performace if you ensure input is ascii.

str: String

String to hash.

asciiOnly: Boolean (default: false)

Specify the string encoding is ASCII.

sha224(str, asciiOnly)

Hash string to sha224, set asciiOnly to true for better performace if you ensure input is ascii.

str: String

String to hash.

asciiOnly: Boolean (default: false)

Specify the string encoding is ASCII.

Example

Code

sha256('');
sha256('The quick brown fox jumps over the lazy dog', true);
sha256('The quick brown fox jumps over the lazy dog.', true);
sha224('');
sha224('The quick brown fox jumps over the lazy dog', true);
sha224('The quick brown fox jumps over the lazy dog.', true);

Extensions

jQuery

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

Code

jQuery.sha256 = sha256
jQuery.sha224 = sha224

And then you could use like this:

$.sha256('message');
$.sha224('message');

Prototype

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

Code

String.prototype.sha256 = function() {
  return sha256(this);
};
String.prototype.sha224 = function() {
  return sha224(this);
};

And then you could use like this:

'message'.sha256();
'message'.sha224();
