The incredibly tragic belated lesson of public key cryptography is this: Trust means trust. There is no shortcut and no substitute for it; if you trust someone, you are really trusting someone. If the person you trusted is abusive, you are really subject to the consequences. If you don't have a reason to trust someone or something, software cannot provide one.

In the blurbs for PGP, it used to say "Communicate securely with people you have never met!", which was the amazing technical achievement of public-key crypto. However, it should have added "Still have absolutely no idea whether they are who they say they are, or whether you should trust them!".

(on peacefire-technical)

(Speaking of that, my GPG key is on Drew Steib's keyserver (although I didn't put it there! Do you trust that key? As a great cryptographer once said, "Why?".).

I spent a long time talking about PKI and I think I now understand it well enough to substantiate my claim that it's "incredibly tragic". See also Carl Ellison's padlock page and the 10 Risks of PKI.
