encrypt decrypt javascript
Install a Node.js package that can handle encryption and decryption, such as CryptoJS or Node.js Crypto.
Require the encryption module in your code with the following line:
javascript const CryptoJS = require('crypto-js');
Use a strong encryption algorithm and a secret key to encrypt a string, like this:
javascript const encryptedMessage = CryptoJS.AES.encrypt('your message', 'your secret key').toString();
To decrypt the message, use the following code:
javascript const bytes = CryptoJS.AES.decrypt(encryptedMessage, 'your secret key'); const decryptedMessage = bytes.toString(CryptoJS.enc.Utf8);
Handle the encrypted and decrypted messages based on your application's requirements.
Remember to keep the secret key secure and use proper key management practices for encryption.
