How to set up a secure chat using netcat

Question

I use netcat to chat in LAN.

PC1 listen port 8080

$ nc -l -p 8080

PC2 connect to PC1:8080

$ nc 192.168.10.1 8080

Unfortunately, this is not secure. Anyone sniffing packets can intercept my messages.
How can I chat securely?

Answer 2

SSH would be an easy way. SSH to the machine then use netcat
