And as you might guess from the actual title, this is about user-to-user messages. I'm not sure how useful this is, because a thoroughly secure implementation is unlikely. A server operator could easily MITM your messages, if you don't establish trust through a separate trusted channel.
Thank you. Exhausted and posted the wrong link. Appreciate it.
I'd be confused as to how it would work since most of the fediverse is accessed through webpages or APIs. How do you E2EE for whichever device will connect?
If I really want I can send the key to a friend I guess, but getting that to work on the various devices I may use seems a difficult task.
