This NIP defines new event kinds for encrypted group chat 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 reserves 4 event kinds (104) for immediate use.
It reserves 8 event kinds (1059, 400-406) for immediate use.
