Every time New Encrypted string Generate using AES

Author: AkibDeraiya123Created Feb 23, 2018Updated May 18, 2026

Hello, I'm using crypto-js library with Node.js Encryption/Decryption `(String/ Stringify object).

Issue is that when i try to Encrypt any string then every moment i get different different encrypted strings But when i Decrypt this all the strings then i got the same plain text Which i use for encrypt.

I want to do like same Encrypted string every moment.

Here my node and npm version

Node:- v8.9.1
NPM:- 5.5.1

My code is like this,

var CryptoJS = require("crypto-js");
const Key = '39067A6F8088F81E9C2BB5D46A8C0F60';
const text = JSON.stringify({Key1: 'value1', key2:'key2'});

// Encrypt 
var ciphertext = CryptoJS.AES.encrypt(text, Key);
console.log(ciphertext); // Here i got different different strings every moment for same plain text

// Decrypt 
var bytes  = CryptoJS.AES.decrypt(ciphertext.toString(), Key);
var plaintext = bytes.toString(CryptoJS.enc.Utf8);
 
console.log(JSON.parse(plaintext)); // Print like { Key1: 'value1', key2: 'key2' }

I want to do like that every moment i got same encrypted string for same plain text.

Please help me i'm in stuck.

Thank you in advance :)
