thanks, very useful! Will study nip-17.
About "using everytime a new key" is, in some way, great for private messages because it consent forward secrecy and in the context of nostr it could be useful to hide who is my chat peer/when I sent messages.
How about use nostr npubs/nsecs just for discoverability and then exchange an secret on every message used to derive a new key for the next message (a new npub where deliver the event, specifically). At this point, only a network analisys from relays could try assemble the puzzle.
If I rotate relays over tor at this point theres perfect privacy (the only leak is the first event to "request" the private chat).
