to generate your own key/cert to run a server, you can use openssl req -x509 -newkey rsa:2048 -keyout key.pem -out cert.pem -days 365 -nodes
to run a server or client with openssl (to test interacting with our client/server respectively):
openssl s_server --key key.pem --cert cert.pem (default port 4433)
openssl s_client (defaults to localhost:4433)
and to run our server or client:
python3 server.py --key key.pem --cert cert.pem
python3 client.py localhost 4433
