TCP Socket Application

These are the multithreaded TCP server and client applications written in C for Linux environment. Programs support authentication and message encryption(base64). When connection between server and client is established, send and receive functions run on different thread so main loop keeps running for new connections.

How to compile?

While compiling, you need to specify the libraries that used for multithreading and cryptography.

$ gcc ChatServer.c -o ChatServer -lpthread -lssl -lcrypto
$ gcc ChatClient.c -o ChatClient -lpthread -lssl -lcrypto

How to use?

$ ./ChatServer [Port Number]

In another terminal:

$ ./ChatClient [Port Number] [username] [password]

If your username and password didn't defined in "login.txt", you won't be able to connect to server.
