Requirements to run the client and server.

google protobuf for python and protoc.
make
python 2.7.*
Run make protobuf before to generate necessary python classes.
server.priv to run server and server.pub to run client. (Long term key associated to the server)
- This server key uses curve SECP384R1 for encryption/decryption, any keypair that satisfies this property could be used, given it is in the PEM format.
- A Python file key_generator.py is used to generate such a keypair: ./key_generator.py -g server.

ChatServer:

Run ./ChatServer.py -h for help page.
Binds automatically to 127.0.0.1:4590. Both IP and Port can be configured at launch.
Registers users that connect to it.
Serves a list of connected users if it receives a valid request.
All communications sent over the network are serialized using protobuf.
Multi threaded and can handle multiple requests in parallel.
Implements acknowledgements for all requirements to make UDP slightly reliable.

ChatClient:

Run ./ChatClient.py -h for help page.
Registers automatically to server 127.0.0.1:4590. Both IP and Port can be passed as CLI flags.
Handles sending messages to users registered with the server.
Implements fetching list of connected users with the list command.
Implements sending a message to a connected user and handles the case if no user exists. Chat command line interface implements the following commands: help list exit msg/send signup signin/login signout/logout
help: prints this help page.
list: lists the users connected to the server at this point of time.
exit: exits the application.
msg/send: sends a message to the username supplied, given the user is logged into the server.
logout/signout: signs the user out of the server logged into.
connect: connect to the server on the ip port. Does not log in.
login/signin: login with a username password.
signup: registers a user associated to the password supplied on the server connected to.
