A simple chat terminal that uses UDP hole punching to traverse the NAT.
SDL: https://www.libsdl.org/download-1.2.php
SDL_net: https://www.libsdl.org/projects/SDL_net/release-1.2.html
Use cmake to build the project:
https://cmake.org
Create a server. You can use something like:
https://www.virtualmaster.com/virtualmaster/referral/29rj1q
On the server run:
python serverS.py
Change proxyIpAddress to point to the new server.
Run host as:
Chat.exe --host -n Bob
Run client as:
Chat.exe --client -n Alice
A password is generated on the host. Once connected, the application drops the communication with the server and messages are encrypted using 256bit encryption. The client should enter the password to be able to decrypt messages.
