Free SSL certs with StartSSL
StartSSL™ Certificates & Public Key Infrastructure - How to Install.
I've always been frustrated by the fact that SSL certs for a website run in the $70/year and up range, which sets https (without having to deal with annoying untrusted certificate warnings and errors) beyond my limited, hobbyist budget. However, I recently heard about StartSSL offering free basic certs, so I set it up today.
After a bit of fiddling (the SSL way of doing things is new to me), it's all up and working! At first only Chromium was calling my site verified, Firefox wasn't giving a bad cert error but was not convinced of the site's authenticity, and Fennec & the Android browser were giving me unknown cert errors. It turned out I hadn't installed the chain certs (a new concept to me), but once I got those in, everything was golden.
