Is Nostr-double-ratchet compatible with the libsignal of the Signal protocol?
Nostr-double-ratchet tests finally passing. Both ratchets should be working now, but don't take my word for it 😄
Signal-style 1-on-1 chat encryption in ~200 lines of typescript. Now just need to make it work again on iris.to and then other clients. https://github.com/mmalmi/nostr-double-ratchet

Unfortunately not, it's an implementation based on nostr keys, events and nip44 encryption from nostr-tools.
