This NIP defines new event kinds for encrypted group events, with chat as the primary example, and with optional forward secrecy guidelines. This NIP defines new event kinds for encrypted group events, with chat as the primary example, and with optional forward secrecy guidelines.
This NIP builds on the encryption from NIP-44, the gift-wrap of NIP-59 and the distributed chat channel management of NIP-28. It is similar to NIP38, with the exception that gift-wrap is used on every message, and issues like metadata leakage and optional forward secrecy are addressed.

It works by creating a shared secret that is used to encrypt the group or channel messages. Only the participants know that secret, so only such members can read/write to this group chat. This effectively hides metadata from external users. See drawbacks below. It works by creating a shared secret that is used to encrypt the group or channel messages.
