Much of the work in our project centers around open protocols.
We use as much of what we find as is, but new ideas sometimes
call for new protocols, and the design of these is a bit of a
roller-coaster ride. KXOVER is an interesting example.
OpenPGP is a powerful technology for signing and encryption, because it
does not imply a stiffling key infrastructure. Instead, it uses a
Web Of Trust that is flexible... and complicating for new users. We now
introduce an approach to securely use OpenPGP without even that.
