This NIP defines a way for two clients to derive `one-use-only` keys for sending and recieving `kind:4` events.
## Motivation
The content of `Direct Messages` [NIP-04](https://github.com/nostr-protocol/nips/blob/master/04.md) is encrypted, but everyone can see who is chatting with whom. This is far from ideal from a privacy perspective.

This NIP describes a way to obfuscate DM communications from the "general public", it does not deal with the relay tracking of clients (for that see [NIP XXX](xxx)).
## Suggestion
For the maximum of privacy the two participants of a `Direct Message` exchange SHOULD use a different public key for each `kind:4` event.
