I somewhat agree. I feel like this is a nice glossary that I could hand my boss so he would understand what we’re talking about and stop asking what each one is, but he still wouldn’t really “get” the process for any of the examples.
If it tried to explain the full process you’re now diving into the explanations of GPG and buying SSL certs, etc and that feels like their eyes would simply glaze over.
I would like to see a tad more separation between the types of PKI (specifically GPG vs TLS type clarity).
However for anyone who doesn't have the requisite background it will just be abstract and impenetrable.
