How can I use Crypto-JS for secure data encryption?

You can use Crypto-JS by including it in your project and utilizing its encryption methods like AES or SHA.

Can you show me a simple example of AES encryption?

Sure! Here's a basic example:

var CryptoJS = require('crypto-js');
var ciphertext = CryptoJS.AES.encrypt('my message', 'secret key 123').toString();
console.log(ciphertext);

How do I decrypt the message back?

You can decrypt it using:

var bytes  = CryptoJS.AES.decrypt(ciphertext, 'secret key 123');
var originalText = bytes.toString(CryptoJS.enc.Utf8);
console.log(originalText);

What are some best practices for using Crypto-JS?

Always use a strong key, avoid hardcoding secrets, and consider using environment variables for sensitive data.
