How do I implement TLS in WebSockets?

To implement TLS in WebSockets, you need to use the 'wss://' protocol instead of 'ws://'. This ensures that the connection is secure.

What are the steps to set up a secure WebSocket server?

First, obtain an SSL certificate. Then, configure your WebSocket server to use this certificate and listen on the appropriate port.

Can you give me an example of code for a secure WebSocket server?

Sure! Here's a simple example using Node.js:

const WebSocket = require('ws');
const https = require('https');
const fs = require('fs');

const server = https.createServer({
  cert: fs.readFileSync('path/to/cert.pem'),
  key: fs.readFileSync('path/to/key.pem')
});

const wss = new WebSocket.Server({ server });

wss.on('connection', (ws) => {
  ws.on('message', (message) => {
    console.log('received: %s', message);
  });
  ws.send('Hello! Message from secure server.');
});

server.listen(8080, () => {
  console.log('Secure WebSocket server is running on wss://localhost:8080');
});

Make sure to replace the paths with your actual certificate and key.

What are the common issues when implementing TLS in WebSockets?

Common issues include certificate validation errors, mixed content warnings, and firewall restrictions that block the secure port.
