NIP-17: Private messages
Private messages compose signed and encrypted envelopes. Relays transport ciphertext rather than a public plaintext conversation.
Implementation
The production relay advertises NIP-17. The browser encrypted-deck path already uses the existing NIP-44 and gift-wrap plumbing.
Example
This demo reads a frozen public NIP-11 capability document. It does not execute this NIP on a relay.
What remains
A complete shared Coax private-message client and its NIP-59 composition remain unfinished.
