Encrypted communications over sockets?

Question

Node.js

Good evening! My question is: I have a chat written on sockets (Node.js + Socket.io) and I would like messages from the client to the server (and vice versa) to be sent in encrypted form. How can this be implemented? Will buying and installing an ssl certificate solve this issue? It is important that messages are encrypted in both directions so that when traffic is intercepted, they cannot be read directly.

Answer 1

ssl will solve the issue 100%
