El Gamal Encrypted Chat

Server / Client Unix chat implementation based on "El Gamal" Encryption Scheme. Extension of http://www.theinsanetechie.in/2014/01/a-simple-chat-program-in-c-tcp.html.

How to compile

Compile Server / Client separately:

gcc -pthread -o server server_chat.c
gcc -pthread .o client client_chat.c

Then start server and client in two different shells:

./server
./client

Instructions

You can modify the numbers exchanged during the server/client handshaking inside the code (#DEFINE P ecc.). Be aware that numbers are stored in "long" variables, so try to avoid using very long digits.
