How can I enforce mutual authentication using Python's socketserver.TCPServer?

Question

I'd like to expose a simple TCP server written in Python to the internet. To authenticate clients, I'd like to rely on both client and server certificates. Does socketserver.TCPServer support this mode by default? If not, can you suggest how to extend the server to implement mutual authentication?

Answer 1

The default library doesn't handle secure sockets (SSL/TLS). Assuming you want to use that specific library no matter what, here's another discussion that shows a way to do it using the OpenSSL libraries.

If you want to write a server application, you might want to use Twisted, an event-oriented framework for writing network applications in Python. Here's the relevant documentation on how to enable SSL for a TCP server.
