Gossip should generate a client key, store it as an ncryptsec under the user's same password, next time they use that password to login. This eventually becomes a device key in the keychains NIP too (rather than their current npub/nsec which will eventually be revoked).
Gossip search for 10044 events to see if an encryption key already exists.
If a 10044 exists, gossip publishes a 4454 and subscribes to the matching 4455. This has to persist across gossip sessions. Eventually if a 4455 comes in, gossip unwraps it and saves the encryption key.
If a 10044 does not exist, gossip generates an encryption keypair (saving it under the same password ncryptsec) and publishes a 10044.
Once an encryption keypair is achieved, gossip uses it to do DMs --- this part is not specified anywhere yet.

While #1647 is still a draft I can only do 1, which is done, so this is on hold
