Really cool, this way even if your private key is leaked they won't be able to decrypt your dm.

E2EE DMs are coming to Nostr 🔒

After being nerd sniped by hearing NVK (npub1az9…m8y8) mention OTR for the millionth time on the Bitcoin Review podcast, I spent the last few weeks digging into OTR, the Signal protocol, and a grab-bag of other cryptography.

The end result is that I (am pretty sure at least) that I found a way to do E2EE (end-to-end encrypted) DMs on Nostr in a way that is both forward and post-compromise secure AND doesn't require any centralized servers.

Huge thanks to Max Hillebrand (npub1klk…x3vt) and PABLOF7z (npub1l2v…ajft) for the chats while I worked out the details.
