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');

var hash = sha256.create();
hash.update('Message to hash');
hash.hex();

var hash2 = sha256.update('Message to hash');
hash2.update('Message2 to hash');
hash2.array();

// HMAC
sha256.hmac('key', 'Message to hash');
sha224.hmac('key', 'Message to hash');

var hash = sha256.hmac.create('key');
hash.update('Message to hash');
hash.hex();

var hash2 = sha256.hmac.update('key', 'Message to hash');
hash2.update('Message2 to hash');
hash2.array();

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

var sha256 = require('js-sha256');

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

It supports AMD:

require(['your/path/sha256.js'], function(sha256) {
// ...
});
