Krypto-js

JavaScript-Bibliothek von Krypto-Standards.

Node.js (Installieren)

Bedarf:

• Node.js
• npm (Node.js-Paketmanager)

1
npm install crypto-js

Usage

ES6-Import für typischen Anwendungsfall für API-Callsigning:

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));

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

Einschließlich aller Bibliotheken für den Zugriff auf zusätzliche Methoden:

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