Signal uses asymmetrical encryption - your private key is very well able to prove your identity - I'm pretty sure the concept "identity" in Signal is built on that technology. But for contacting people - well - what else would you suggest?!
- darklajid 11y agoHi plusquamperfekt. I don't know your mail address or telephone number. If this message manages to reach you - can you explain your point a bit more? If the private key would _be_ the identify, that'd be awesome. And maybe I fail to understand ChatSecure/Signal. I'd be glad to be corrected. But as far as I understand, that system ties a user to a mobile number, because 'that is as good a unique identifier as we get' and uses that instead. I think Threema does what you describe - or at least expects you to exchange keys via QR code when you physically meet? My gripe with telephone numbers is this: I don't want to be tied to an identity I cannot control, to an identify that is public knowledge and unchangeable. I want to contact people via IM without them being able to call me. Phone numbers are for calls (okay, texts for historical reasons).
- plusquamperfekt 11y agoI think the identity is connected to what key pair you control / what private key you have on your phone. F.x. I installed a while ago Signal on my phone and recently went to another country where I used a different SIM card (hence a different phone number) and I could still use my Signal app as usual.
