How could then sync end-to-end encrypted messages?
- kobayashi 11y agoSame way iMessage does
- dmix 11y agoThe same way Signal does is probably a better example.
- danieldk 11y agoKeep in mind that Whatsapp still supports pretty old devices (Nokia S40/60), where you may not want to encrypt every image N times. Edit: remove some stuff.
- kccqzy 11y agoActually iMessage doesn't encrypt each image N times. It encrypts once, upload it to a server, then encrypts the image encryption key N times.
- motoboi 11y agoSender encrypts same message several times, one for each receiver device. Store them the same way they store today. When the first device picks up the message, mark as delivered, when the user reads it, mark as read. Something along those lines, I guess. EDIT: message is encrypted, but not it's metadata, as the server must know where it came from and where it is going to.
- camillomiller 11y agoConsidering how much information about a subject is inferrable by means of metadata only, I'd say this is a much better solution, security wise.
