Suggestion: after first message with someone, tag posts not with their public key, but a key derived from shared secret.
That hides further messages from the public eye. Basically, only the initial message request is public.
tag: hash(shared secret + their public key)
interesting!
Used to do this in Iris when I was using gundb
Actually this is better so groups can be supported in the future:
tag: hash(shared secret + your public key)
👀
Hi Martti, I wrote a NIP proposal for private messages a few months ago. It’s still a PR but you might find it interesting. It’s still waiting for some more reviews.
