I’ve got about three different lead-ins to this post rattling around my head. There’s the “we don’t have flying cars, but we have public-key cryptography that isn’t completely terrible” angle. There’s the “truly we are living in a William Gibson novel” angle. But I think I’ll take the “here’s a true story about how public-key cryptography is being used right this second” angle. Everybody loves a good anecdote, right? So there’s this fellow by the name of Michael Anderson.
