In this section, we'll look at how to use SSL with our Apache installation. We'll work through enabling SSL, generating certificates, and configuring Apache to use those certificates with both a single site configuration, as well as with virtual hosts.

By default, Ubuntu's Apache configuration listens for traffic on port 80, but not port 443 (HTTPS). You can check this yourself by running the following command:
