Is it possible to enable encrypted connection in socket.io?

Question

Node.js

Maybe there is already a built-in ability to create a secure channel, which I do not know about.
I assume ssl-like encryption.

Answer 1

Yes, SSL available in TCP and at the WebSocket level is not "lost".

Answer 2

Of course there is a built-in ability to use encryption. Create an https server and hang socket.io on it.
