I realize now that I did not answer your question very intelligently. You did not only ask about encryption, you asked where to find info about the project.

I don't have a good answer for that question. There is a nostr telegram group at t.me/nostr_protocol where we have ongoing discussions about nostr stuff, and when I began work on this a few days ago, I posted frequently there with questions and status updates.

My hope is that we'll move discussions like that away from telegram and into nostr itself now that there is a decent nostr-based client with a telegramish interface. But I shouldn't judge the decency of my own project, time will tell whether we move to nostrgram or keep using telegram.

nothing is encrypted yet. Dms will be encrypted when implemented, or at least that's my plan. I might also implement "private groups" where all the messages in the group are encrypted but each member of the group knows the decryption key (or rather their browser knows it). That would work but it's not secure unless everyone in the group is trustworthy, because any group member can publish the decryption key or share it with bad people
