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();// HMACsha256.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();

Node.js

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;

const { sha256, sha224 } = require('js-sha256');

TypeScript

If you use TypeScript, you can import like this:

import { sha256, sha224 } from 'js-sha256';

RequireJS

It supports AMD:

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