    key: 'my_secret_password',
    iv: crypto.randomBytes(16)
});

// String:
const message = 'My Secret Message!';
console.log(`Original Message: '${message}'`);

const encrypted = crypt.encrypt(message);
console.log(`Encrypted Message: '${encrypted}'`);

const decrypted = crypt.decrypt(encrypted);
