Give advice on how to properly encrypt TCP in my case?

Question

JavaScript

We have a master server and many gateways. We have a master, and clients have gateways.
I decided not to invent my own protocol and took the json-socket module, which conveniently knows how to transfer JSON over tcp.
The problem is that clients need data security (data is not very valuable, but you can not allow someone to infiltrate and send their command to the gateway).
How to encrypt data and with what?

Answer 1

TLS ?

Answer 2

Drop this perversion. Websocket to help you. In general, I really want to try playing with nginx or stunnel
