Ahh, i think i get it. but that brings us back to my question; how is the data store on the server, Encrypted or plaintext? if its encrypted would that mean decryption happens per each session. e.g. when using whatsapp web ( could it be why they need the phone to be online? ) |

How I would do it was by distributing keys to devices at login and let friends use a users public key to encrypt messages to him.
Now you pack that encrypted message in a metadata envelope, send to server to be later retrieved by the owner.
The keys should never leave the device.
