It's funny how people seem to do the same thing at the same time. I recently made https://github.com/socketry/localhost however `mkcert` has lots of good ideas I'm going to "borrow" :)
Me too, but it was mostly to teach myself about OpenSSL, and I feel like the experience have scarred me for life.
I mostly used the Ruby C-bindings, and I feel like finding information and documentation was very difficult, and it was even harder to figure out if there was any best practices I was missing.
It baffles me that so important infrastructure is built upon something that feels this brittle, and it keeps me up at night :-)
