CODE EXAMPLE FOR TYPESCRIPT

nodejs encryption 128bit

import * as crypto from "crypto";

const algorithm:string = 'aes-128-ecb';

// Encryption
const plaintextEnc:Buffer = Buffer.from('0123456789012345');

const ciphertext:Buffer = Buffer.concat([cipherEnc.update(plaintextEnc), cipherEnc.final()]);

// Decryption
