So Activpub needs an actor with an inbox and outbox to send and receive content. A did is a virtual actor that reroutes to a real actor and collects content across real actors.

Gpg public keys have a dedicated email address field. And if you don’t want to share your “real” email address then just make a new one.

And the did stores ur profile picture a public key display names bio etc etc.

Yeah that’s a pain point I experienced with Gpg armored packets, I couldn’t figure out a way to pack in a PFP. Even shrinking it to 64x64 made the public key file feel too heavy. So I just decided profile pics are out of scope and you should just use gravatar.

U could use pgp as the key in the did if the devs want to support it as a cryptography protocol. The did is also used to sign each message similar to pgp. U simply need more functionality than what pgp provides.

I 80% agree. I do wish PGP armored packets had extra fields and if that’s an RFC that could be sent to the Gnupg maintainers then gpg would be absolutely perfect but I haven’t gotten around to figuring that out. All things considered since GnuPG already exists and it’s already installable everywhere and it already works I figured I could just roll with it for userless atleast. I want to use GPG for all user authentication related concerns.
