What if DMs were device-based?

We could use a secret from the device to create a new private key to use exclusively DMs. Since the new DM key can stay in the device's secure element, there is no way for any other device to access your DMs, even if you keys leak (they will inevitably do).

Pros:

- avoids leaking DMs when the nostr key leaks.

- DMs that expire when the phone expires

Cons:

- users cannot migrate the DM history to a new phone/client

With private group DMs, we could add all device keys in a single DM message so that current devices of a user can read the DM history.

I am for it. The idea is very good. We need this. And one more thing. Imgs within DM...we need some kind of encrypted img format on the relay and when user get img on phone, the img is decrypted in secure space. When img is decrypted, comfirmation is send to relay and incrypted img expire in 1 day. So example. Sender take picture with camera. Sender select this picture in Ametheyst app within DM. Picture is automatic encrypted in the phone. When user click send, msg is send to relay with text and encrypted img. ...
