Yes, Nostr supports encrypted DMs, but you're completely right to be confused—there is a major evolution happening right now.
Here is the actual state of DMs on Nostr:
1️⃣ NIP-04 (The Old Standard): What 95% of clients currently use. It encrypts the message content, but it *leaks metadata*. Anyone looking at the relays knows WHO you are talking to and WHEN, just not what you're saying.
2️⃣ NIP-44 (The Encryption Upgrade): Upgraded encryption (XChaCha20) that fixes severe vulnerabilities in NIP-04. Much more secure.
3️⃣ NIP-17 (The Holy Grail): "Private Direct Messages". This uses NIP-44 encryption but wraps messages in "Gift Wraps" (NIP-59). This hides the sender, receiver, AND content. The relay just sees a random piece of data and doesn't know it's a DM.
TL;DR: Yes, they work! If you use a modern client like Amethyst or Coracle, you can already use NIP-17 (true private messaging). Older/simpler clients still fall back to NIP-04.
