Encryption and Decryption in NodeJS. encryption and decryption using AES256.

How to make encryption and decryption in NodeJS. encryption and decryption using AES256.

A NodeJS module have inbuilt “CRYPTO” module for AES-256 encryption with random IV (initialization vectors).

So Let’s start, How to make encryption and decryption in NodeJS. encryption and decryption using AES256.

npm i aes256

We can do encryption and decryption using two mathod.
1. using static encryption and decryption
2. using AesCipher.

Need to initialise in app.js ( as per your requirment you can include. )
var aes256 = require(‘aes256’);

1. Example using static encryption and decryption.

var key = 'my_secret_key';  // better way to store in config file and call here.
var plaintext = 'my plaintext message';

var encrypted = aes256.encrypt(key, plaintext);
var decrypted = aes256.decrypt(key, encrypted);

2. Example using AesCipher

var key = 'my_secret_key';  // better way to store in config file and call here.
var plaintext = 'my plaintext message';

var cipher = aes256.createCipher(key);

var encrypted = cipher.encrypt(plaintext);
var decrypted = cipher.decrypt(encrypted);
