How do I use CryptoJS in a Vue 3 application?

To use CryptoJS in a Vue 3 application, first install it via npm with npm install crypto-js. Then, you can import it in your components.

Can you show me an example of encrypting a message?

Sure! Here's a simple example:

import CryptoJS from 'crypto-js';

const message = 'Hello, World!';
const secretKey = 'mySecretKey';
const encryptedMessage = CryptoJS.AES.encrypt(message, secretKey).toString();
console.log(encryptedMessage);

How do I decrypt the message?

To decrypt the message, you can use the following code:

const bytes = CryptoJS.AES.decrypt(encryptedMessage, secretKey);
const decryptedMessage = bytes.toString(CryptoJS.enc.Utf8);
console.log(decryptedMessage);

Are there any security concerns I should be aware of?

Yes, always ensure that your secret keys are stored securely and not hard-coded in your application. Consider using environment variables.
