Crypto Module in Node.js

const crypto = require('crypto');

// Hash
const hash = crypto.createHash('sha256')
  .update('password')
  .digest('hex');

// Random
const token = crypto.randomBytes(32).toString('hex');

// Encrypt/Decrypt (createCipher removed in Node 22 - use createCipheriv)
const key = crypto.scryptSync('password', 'salt', 24);
const iv = crypto.randomBytes(16);
const cipher = crypto.createCipheriv('aes-192-cbc', key, iv);
let encrypted = cipher.update('text', 'utf8', 'hex');
encrypted += cipher.final('hex');
