This project is a real time end-to-end encrypted secure chat application. This app utilizes AES to encrypt messages, MAC's to ensure message integrity and Diffie-Hellman Key Exchange to generate the AES and HMAC keys.

To get started, you must be on a Linux Operating System. I am assuming you are on a Linux Operating System moving onward.

1. Clone the repository using the following command:

git clone https://github.com/dddictionary/Secure-Chat.git

2. Run make to compile the files into executables. If there are any issues with compiling, run make clean and then running make
3. You can run ./chat -h to view the list of possible commands.
4. To beginning listening on one machine, run ./chat -l. This will default to listening on port 1337.
5. On another terminal instance, run ./chat -p 1337 to connect to the port.

OPTIONAL:
If you host a port forward, you can allow others to connect to your computer and chat with you while being connected to different routers!
The command for that is:

./chat -c <ip-address>

where ip-address is the IP address of the host machine.

The app was made by the following:
