Example: AES encryption with mode CBC and Initialization vector
const crypto = require('crypto');
const algorithm = 'aes-128-cbc';
const key = '1234567890123456';
const iv = '1234567890123456'; // Initialization vector.
const cipher = crypto.createCipheriv(algorithm, key, iv);
let encrypted = cipher.update('some clear text data', 'utf8', 'hex');
encrypted += cipher.final('hex');
console.log(encrypted);
