This is a continuation of the previous entry.
So there I was, in some kind of thought-frenzy, wondering why no one was harnessing public key encryption to solve this problem. We already had something similar working with ssh, where you can set up to authenticate you without a password by using an authorized key. I’m not a cryptographer (ologist? Which is correct?) so I don’t really know how viable my idea was, but basically I wanted some way to authenticate myself to all these internet fora, blogs, and maybe even e-commerce sites. Why not?
