Security of socket on vserver

[phillipschroder]

To secure your Python socket server application, you can use SSL (Secure Socket Layer) to encrypt the data. You can use the Python SSL library to provide TLS encryption in socket-based communication between Python clients and servers. It uses cryptography and message digests to secure data and detect alteration attempts in the network. Digital certificates provide authentication.

Here is an example of how to use OpenSSL to wrap your packets in SSL:

import ssl

context = ssl.create_default_context(ssl.Purpose.CLIENT_AUTH)
context.load_cert_chain(certfile="server.crt", keyfile="server.key")

with socket.socket(socket.AF_INET, socket.SOCK_STREAM, 0) as sock:
    sock.bind(('localhost', 8443))
    sock.listen(5)
    with context.wrap_socket(sock, server_side=True) as ssock:
        conn, addr = ssock.accept()
        with conn:
            print('Connected by', addr)
            while True:
                data = conn.recv(1024)
                if not data:
                    break
                conn.sendall(data)

I hope this helps. Let me know if you have any other questions.
