How do I replace deprecated crypto.createCipher in Node.js?

So lets say it like:

Replace deprecated crypto.createDecipher usage with crypto.createDecipheriv

why? because:

according to the deprecation docs it was due to security concerns.

Using crypto.createCipher() and crypto.createDecipher() should be avoided as they use a weak key derivation function (MD5 with no salt) and static initialization vectors. It is recommended to derive a key using crypto.pbkdf2() or crypto.scrypt() and to use crypto.createCipheriv() and crypto.createDecipheriv() to obtain the Cipher and Decipher objects respectively.

As per crypto_crypto_createdecipher_algorithm_password_options, one now need to switch to crypto.createDecipheriv.

Sample Code:

const crypto = require('crypto');
const algorithm = 'aes-256-ctr';
const ENCRYPTION_KEY = 'Put_Your_Password_Here'; // or generate sample key Buffer.from('FoCKvdLslUuB4y3EZlKate7XGottHski1LmyqJHvUhs=", "base64');
const IV_LENGTH = 16;

function encrypt(text) {
    let iv = crypto.randomBytes(IV_LENGTH);
    let cipher = crypto.createCipheriv(algorithm, Buffer.from(ENCRYPTION_KEY, 'hex'), iv);
    let encrypted = cipher.update(text);
    encrypted = Buffer.concat([encrypted,]);
    return iv.toString('hex') + ':' + encrypted.toString('hex');

function decrypt(text) {
    let textParts = text.split(':');
    let iv = Buffer.from(textParts.shift(), 'hex');
    let encryptedText = Buffer.from(textParts.join(':'), 'hex');
    let decipher = crypto.createDecipheriv(algorithm, Buffer.from(ENCRYPTION_KEY, 'hex'), iv);
    let decrypted = decipher.update(encryptedText);
    decrypted = Buffer.concat([decrypted,]);
    return decrypted.toString();

For complete running example clone node-cheat and run node crypto-create-cipheriv.js.
