While messing around with a new membership database I ran into a wall. The script that gives me a web interface simply would not continue until I secured my connection properly. So, I found myself in need of a do-it-yourself certificate (since I wasn't willing to pay $500+ for a real certificate yet).
I found a great set of instructions on Paul Bramscher's Site:
I read through them and, although I didn't understand all the steps fully, I was able to make it work.
Thanks Paul Bramscher!
