WebSockets are great for real-time and long-lived communications. (This is different from the “hello world” example, which uses port 9876; sorry for the confusion. The WebSocket help to create realtime application, A real-time application allows information to be received as soon as it is published, rather than requiring a source to be checked periodically for (PowerShell) Send and Receive WebSocket Messages. That’s because ws:// data is not encrypted, visible for any intermediary. Continue reading Securing WebSocket using wss and HTTPS/TLS (Tech Tip #50) → Miles to go 4. Nowadays it’s widely supported and its A WebSocket application can be made secure because various standards provide for that possibility. x releases.


websocket. TLS/SSL protects data from modification during transit and verifies its authenticity. So you could, for example, tunnel a database connection directly through to the browser. The WSS protocol is to WS what HTTPS is to HTTP: the connection is encrypted with TLS. Web browsers use the http protocol and modern ones can also use websockets.
