We love Nostr as a publishing platform that offers unparalleled censorship resistance. But NIP44 does NOT provide most of the important qualities of e2e encryption: - break-in recovery. - repudiation (deniability). - visibility of connection graph to observers. - fixed message sizes (although it can be provided by the specific app) - resistance to Shore algorithm (PQ encryption). It's unclear whether it provides forward secrecy, but the spec implies that it does not - I might be wrong here. We wrote this post about the qualities of e2e encryption and why they are important:

Let's break down @npub1tm99...xn72 a bit The app has default gift wrapped nip44 DM's with encrypted content and minimizes meta data leak. The app also offers "Secret Chat" DM which is the gift wrapped DM plus a nip101 key exchange. °To use the Secret Chat you need to tap on the user profile, then tap secret chat button. °This opens an option screen to choose a trusted relay, the time interval to exchange keys, and length of request time out. °Also under 'more' on the user profile you can request auto delete of messages. The other user has to agree. °The secret chat also has a screen shot notification. Amber can be used to sign in and protect your nsec. Use a vpn, tor/orbot. "Home" will show all messages. "Contacts" shows your saved nostr contacts, groups and channels. "Discovery" shows your follows nostr feed and is called "moments" and also has "channels" tab. "Me" is your profile where you can manage settings and ecash wallet plus just see your own "moments" The app has a lot going on. Under "Home" you can create a new "Group". °Groups can be Open, Closed or Private. ° Open groups anyone can join and see ° Closedd groups is invite only ° Private groups are gift wrapped dm to each member There is also a cashu ecash wallet in app.

No, but it's a very similar design with relays. Nostr has largely failed to provide a private and secure DM protocol so far so that should be a good thing.
