First app: Encrypted Chat

i am so happy, i have wrote the FIRST thingy on top of secure channel protocol!!! my own damn lil TLS.

this is a very basic client server chat, server listens on a port and client connects, they it reads input from stdin

the server connects using command:

./scp listen --port 2008 --psk test

the client connects using command:

./scp connect --host localhost:2008 --psk test

the PSK is pre-shared (well, duh) using the --psk flag

well this is a very basic terminal chat app, i can ship the project as it is rn as its a nice MVP but i want to make a visualizer cuz i know damn well NO one gonna run it like this lol, and i want to make a cool visualizer that shows every step of handshake

the first screenshot shows the chat, top one is the server and bottom is client
the second screenshot shows the wireshark capture of this beautiful exchange, ofc its encrypted hehe i love this
