The Evolution of Finger: using a single factory for multiple protocols
======================================================================
Introduction
------------
This is the eighth part of the Twisted tutorial :doc:`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 :doc:`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:
.. code-block:: bash
openssl req -x509 -newkey rsa:2048 -keyout key.pem -out cert.pem -days 365
