Encrypting Traffic with TLS and wss://
Protect WebSocket data in transit by serving connections over TLS, upgrading ws:// to the secure wss:// scheme in a Spring application.
Why Plain ws:// Is Risky
A WebSocket opened over ws:// sends every frame as plaintext. Anyone on the network path can read or tamper with the messages.
For any real application you must encrypt the channel, just as you would with HTTPS.
Introducing wss://
The wss:// scheme is WebSocket over TLS. It is the exact analogue of https://: the handshake and all subsequent frames travel inside an encrypted tunnel.
ws://→http://wss://→https://
