> However, when you want good encryption, user experience always comes after security I'm going to throw down a gauntlet: encryption design that doesn't start with designing for the human users is already fundamentally broken. Why? Because it cannot represent a solid system. This isn't machines in the Matrix talking to one another: the needs of the human users are the only thing that matters. Combine that with the past few decades of experience in software encryption systems, and we realize that this is hard to achieve. The non-adoption and misuse of GPG that Moxie speaks of, the train-wreck of passwords, and so on. It really feels like we've hit a wall, where there are no significant gains to be had unless these design problems are taken seriously. "Perfect" cryptosystems that have major real-world usability flaws are in fact worthless. Implementing new systems of this kind is a waste of effort and a disservice to everyone who vitally needs the services of a robust encryption infrastructure.
