I'm so scared of my certificate renewal script. It's really cool and sends me a summary via email of the executed tasks and runs automatically every month. But when I look at the code I don't know what the hell I was thinking when I wrote it. I mean, it even fetches the certificates prior to renewing them and then re-fetches them afterwards in order to make sure that the servers are actually using the new ones.
