The Evolution of Finger: using a single factory for multiple protocols

Introduction

This is the eighth part of the Twisted tutorial Twisted from Scratch, or The Evolution of Finger <index> .

In this part, we add HTTPS support to our web frontend, showing how to have a single factory listen on multiple ports. More information on using SSL in Twisted can be found in the SSL howto <../ssl> .

Support HTTPS

All we need to do to code an HTTPS site is just write a context factory (in this case, which loads the certificate from a certain file) and then use the twisted.internet.endpoints.serverFromString method to build a SSL endpoint. Note that one factory (in this case, a site) can listen on multiple ports with multiple protocols.

Of course, this endpoint doesn't work without a TLS certificate and a private key. You'll need to create a self-signed cert and key. This will obviously not be trusted by your web browser, so you'll see a warning when you connect. In this case, don't worry: you're not at risk.

To create a certificate and key that can be used by this tutorial, run the following:

openssl req -x509 -newkey rsa:2048 -keyout key.pem -out cert.pem -days 365
