Ein Ansatz, den Schlüsselaustausch im PGP-System sicherer und für den Benutzer einfacher zu gestalten, ist der OPENPGPKEY-Draft der IETF. Mit der dort beschriebenen Methode kann der Besitzer einer E-Mailadresse den zur Adresse passenden (öffentlichen) PGP-Schlüssel im DNS veröffentlichen.

Keyringer lets you manage and share secrets using GnuPG and Git with custom commands to encrypt, decrypt, recrypt, create key pairs, etc.

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.
