It's kinda a wild fact that there are these Internet Protocols that are used extremely widely, but knowledge how they work is scarce.
For reasons, I just wondered a few things about OCSP. That's part of TLS, and, idk, most people would probably attribute "knowledge of TLS" to me.
Yet... I kinda know what OCSP does, but... I don't really know how the protocol works.
And if I google for something like "easy explanation of OCSP", I don't find anything that would give me a brief intro.
