Publishing PGP keys is a pain. There are many disjoint keyservers, three or four networks of which, which do (or don't) share information with each other. Some are corporate, some are private. And it's a crapshoot as to whose key is going to be on which, or worse, which will have the latest copy of a person's key.

For a long time, GPG has had a way to publish keys in DNS, but it hasn't been well documented. This document hopes to change that.

Keybase is a website, but it's also an open source command line program. Let's walk through a terminal example, which illustrates what Keybase does. All of this can be embedded into other software, written by anyone.
