Updating SSH Certs

At some point soon I should sort out how to clean up the unused site folders on my little Raspberry Pi server, and configure a chron tab to auto-update the SSL certs.

But for now, it's not automated, and by the time the certs expire, I only sort of vaugely remember what I did to update them.

There's not really much to it, but since I only have to do this once every few months, it's nice to have a reminder of what to do.
