I proudly installed my first GoDaddy cert back in 2014. A regular cert is only valid for a single specific site, in my case, spencerponte.com. It is not valid for subdomains like this blog. For that you would need a wildcard cert, which covers all subdomains as well. Unfortunately GoDaddy was charging more than four times the price of a regular cert to get a wildcard, so that was out of the question. Another option, buying two different certs also seemed expensive and annoying.
And so for the last couple years this blog has done without HTTPS. I’ve been learning a lot about Let’s Encrypt though, and decided to give it a shot. Let’s Encrypt is a new, free, open certificate authority that takes a different approach to validation.
