React | Encryption and Decryption Data/Text using CryptoJs

To encrypt and decrypt data, simply use encrypt() and decrypt() function from an instance of crypto-js.

Node.js (Install)
Requirements:
1.      Node.js
2.      npm (Node.js package manager)
3.      npm install crypto-js

npm install crypto-js

Usage -

Step 1 - Import

var CryptoJS = require("crypto-js");

Step 2 - Encrypt

  // Encrypt
  var ciphertext = CryptoJS.AES.encrypt(JSON.stringify(data), 'my-secret-key@123').toString();

Step 3 -Decrypt

  // Decrypt
  var bytes = CryptoJS.AES.decrypt(ciphertext, 'my-secret-key@123');
  var decryptedData = JSON.parse(bytes.toString(CryptoJS.enc.Utf8));


As an Example,

 import React from 'react';
import './App.css';
//Including all libraries, for access to extra methods.
var CryptoJS = require("crypto-js");

function App() {
  var data = [{ id: 1, name: 'Anil' }, { id: 2, name: 'Sunil' }]

  // Encrypt
  var ciphertext = CryptoJS.AES.encrypt(JSON.stringify(data), 'my-secret-key@123').toString();
  //log encrypted data
  console.log('Encrypt Data -')
  console.log(ciphertext);

  // Decrypt
  var bytes = CryptoJS.AES.decrypt(ciphertext, 'my-secret-key@123');
  var decryptedData = JSON.parse(bytes.toString(CryptoJS.enc.Utf8));

  //log decrypted Data
  console.log('decrypted Data -')
  console.log(decryptedData);

  return (
    <div className="App">
      <header className="App-header">
        <div>Encrypt Data -{ciphertext}</div>
        <div>
          {decryptedData.map(function (object) {
            //console.log(object)
          })}
        </div>
      </header>
    </div>
  );
}
export default App;
