How can I implement token encryption in my application?

To implement token encryption, you can use libraries like JWT or OAuth. What technology stack are you using?

I'm using Node.js with Express. Any specific libraries you recommend?

For Node.js, I recommend using 'jsonwebtoken' for JWT and 'crypto' for custom encryption. Would you like code examples?

Yes, please provide a code example for JWT token encryption.

Here's a simple example:

const jwt = require('jsonwebtoken');
const token = jwt.sign({ userId: 123 }, 'your_secret_key', { expiresIn: '1h' });
console.log(token);

This generates a token that you can send to the client.
