Web Crypto API - Node 16

 

Experimental Web Crypto API

The Web Crypto API is the newer more well defined version of the Crypto library for JavaScript. All of the new Web Crypto methods are available on the subtle interface. Many browsers used an interface called Crypto without having a specific specification. The Web Crypto API adds a standard to the Crypto library.

import { webcrypto } from 'crypto';
const { subtle } = webcrypto;

(async function() {

  const key = await subtle.generateKey({
    name: 'HMAC',
    hash: 'SHA-256',
    length: 256
  }, true, ['sign', 'verify']);

  const digest = await subtle.sign({
    name: 'HMAC'
  }, key, 'I love node.js');

  console.log(digest);
})();
