How to secure WebSocket connections with TLS/SSL (XAML)

  • Article

This topic explains how to secure WebSocket connections with Transport Layer Security (TLS)/Secure Sockets Layer (SSL) when using the StreamWebSocket and MessageWebSocket features in Windows 8 for a Windows Store app.

In most cases you'll want to use a secure WebSocket connection. This will increase the chances that your connection will succeed, as many proxies will reject unencrypted WebSocket connections.

Instructions

Step 1: Use the wss: URI scheme

The WebSocket Protocol defines two URI schemes. ws: is used for unencrypted connections, while wss: is used for secure connections that should be encrypted.

  • To encrypt your connection, use the wss: URI scheme. For example:

    webSocket = new MessageWebSocket();
await webSocket.ConnectAsync("wss://www.example.com");

Remarks

For additional details on the WebSocket URI schemes, see the WebSocket Protocol.
