Sure. Agreed. I was responding to your statement that you can send encrypted SMS messages using that handy PSTN directory access provided by Signal.
You can't.
I think this is a common misconception.
- motohagiography 6y agoOpen loop criticisms are why I often can't stand other security and crypto people. To be clear, if someone is a Signal user, you use their phone number for directory discovery and initializing identity, then Signal messages themselves are encrypted and transported via Signal servers using WebRTC as a transport protocol? I think without a sequence diagram, most discussion of security protocols is pointless.
- frabbit 6y agoSignal does not send encrypted SMS messages. Period. It can send encrypted messages but they are not SMS. I think that without using the same words that other "security professionals" (which I would not class myself as) use most discussion becomes absolutely pointless.
