For my final project for Network and Secure Programming, me and 2 other team members had to create a chat application which relies on a client to display and recieve messages from other users from a server. There were three parts to the project, one being the client recieving and texting messages to other clients, a server that makes the connection between clients, and a library to hold all of the necessary functions. For this application, we used socket based programming and python.
