> end-to-end only device to device (so I can't swap seamlessly from a desktop to a mobile session)
How do you accomplish a seamless swap from desktop to a mobile session using end-to-end encryption?
How do you accomplish a seamless swap from desktop to a mobile session using end-to-end encryption?
Most seamless end-to-end encrypted solution I've come across. And it's still in beta. Every piece is open source (I'm running my own server), it's federated, supports history sync as a first-citizen feature, individual read receipts for group messages. The UX is not as polished as Telegram, but it's improving rapidly and is more than usable as a daily driver.
The thing which is really sad is that there are no end to end encrypted group chats.
In iMessage specifically, or in general? WhatsApp/Signal do use E2E-crypto for group chats.
e2e is in beta still, but they have key list management/verification in place already.
If it's because Apple tells me so then I think can see that the end to end encryption is broken and interception is possible.
Are old messages re-encrypted with the new key?
This would be even worse.
It would still be possible to implement this in a secure way (including out-of-band key verification) by having the "original" key (the one you've compared out-of-band) sign keys for new devices and have the server deliver that signature (which the sender can then verify). I don't know if there are any implementations of this.
