PIG: End-to-end Encryption in ActivityPub

This is a wonderful proposal. I am a UX designer who is connected to @bumblefudge I have worked with both decentralized protocols that became ActivityPub as well as done extensive UI/UX work on encrypted messaging apps. I have participated in un-conference style events with @evanp over a decade ago and he is wonderful. I would love to to see this proposal accepted and contribute to it.
