Makes sense. Now, how do you go about turning a certificate into something human readable? Serious question, I have *never* seen this discussed anywhere.

Everyone just says "As long as the roots are good you can trust the chain", and that's never made sense to me. The whole "trust what strangers say" system seems more like "Find a way for companies to make money" than any good security system.
