crypto-js

JavaScript library of crypto standards.

Node.js (Install)

Requirements:

  • Node.js
  • npm (Node.js package manager)
npm install crypto-js

Usage

ES6 import for typical API call signing use case:

import sha256 from 'crypto-js/sha256';
import hmacSHA512 from 'crypto-js/hmac-sha512';
import Base64 from 'crypto-js/enc-base64';

const message, nonce, path, privateKey; // ...
const hashDigest = sha256(nonce + message);
const hmacDigest = Base64.stringify(hmacSHA512(path + hashDigest, privateKey));

Modular include:

var AES = require("crypto-js/aes");
var SHA256 = require("crypto-js/sha256");
...
console.log(SHA256("Message"));

Including all libraries, for access to extra methods:

var CryptoJS = require("crypto-js");
console.log(CryptoJS.HmacSHA1("Message", "Key"));

Client (browser)

Requirements:

  • Node.js
  • Bower (package manager for frontend)
bower install crypto-js

Usage

Modular include:

require.config({
    packages: [
        {
            name: 'crypto-js',
            location: 'path-to/bower_components/crypto-js',
            main: 'index'
        }
    ]
});

require(["crypto-js/aes", "crypto-js/sha256"], function (AES, SHA256) {
    console.log(SHA256("Message"));
});

Including all libraries, for access to extra methods:

// Above-mentioned will work or use this simple form
require.config({
    paths: {
        'crypto-js': 'path-to/bower_components/crypto-js/crypto-js'
    }
});

require(["crypto-js"], function (CryptoJS) {
    console.log(CryptoJS.HmacSHA1("Message", "Key"));
});

Usage without RequireJS

<script type="text/javascript" src="path-to/bower_components/crypto-js/crypto-js.js"></script>
<script type="text/javascript">
    var encrypted = CryptoJS.AES(...);
    var encrypted = CryptoJS.SHA256(...);
</script>

AES Encryption

Plain text encryption

var CryptoJS = require("crypto-js");

// Encrypt
var ciphertext = CryptoJS.AES.encrypt('my message', 'secret key 123');

// Decrypt
var bytes  = CryptoJS.AES.decrypt(ciphertext.toString(), 'secret key 123');
var plaintext = bytes.toString(CryptoJS.enc.Utf8);

console.log(plaintext);

Object encryption

var CryptoJS = require("crypto-js");

var data = [{id: 1}, {id: 2}]

// Encrypt
var ciphertext = CryptoJS.AES.encrypt(JSON.stringify(data), 'secret key 123');

// Decrypt
var bytes  = CryptoJS.AES.decrypt(ciphertext.toString(), 'secret key 123');
var decryptedData = JSON.parse(bytes.toString(CryptoJS.enc.Utf8));

console.log(decryptedData);
