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
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');or
var sha256 = require('js-sha256').sha256;
var sha224 = require('js-sha256').sha224;or
const { sha256, sha224 } = require('js-sha256');If you use TypeScript, you can import like this:
import { sha256, sha224 } from 'js-sha256';It supports AMD:
require(['your/path/sha256.js'], function(sha256) {
// ...
});sha256(''); // e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855
