Convincing people to use apps such as Signal is hard work and most can't be convinced. But with those you manage to convince, do you feel happy to talk to them on Signal?
The problem is these people use Signal on Android/IOS which can't be trusted and IOS has recently been in the news for having a backdoor. And it has also been revealed that american feds are able to read everyone's push notifications and they do this as mass surveillance.
So not only do you have to convince people to use Signal which is an incredibly difficult challenge. You also have to convince them to go into settings to disable message and sender being included in the push notifications. And then there's the big question is the Android and IOS operating systems are doing mass surveillance anyway. And many people find it taking a lot of effort to type on the phone so they install Signal on the computer which is a mac or Windows OS.
So I don't think I feel comfortable sending messages in Signal but it's better than Whatsapp.
These were some thoughts to get the discussion started and set the context.
There are no shades of grey in encrypted communications.
Your messages are either plain text or not to 3rd party.
Sometimes it appears to be encrypted, but there loopholes that make it possible to significantly reduce decryption costs. It is plain text to those who put the loopholes, like specially crafted constants in the algorithm.
There are indeed shades of grey. Not only the presence of encryption itself matters, but the metadata, as well as details of the implementation. For example, Signal has all the messages encrypted - but it has the capability to know the identities of everyone and to build their social graph due to centralization.
Signal is not my tool of choice, so I'll answer from a more general perspective:
Having multiple friends and social groups on an e2ee chat system for the past few years feels great. Knowing that our words aren't being recorded and exploited by half a dozen companies, we no longer feel the need to self-censor. The depth and value of our online conversations have grown noticeably.
Yes, there is more work to do, both at the endpoints and in the protocols. No, not all of us have flipped all the switches to maximize our privacy yet. That's okay. Migrating is a gradual process. We do it together, helping each other along the way, rather than trying to force it all at once. Every step an improvement.
Took years to get all the ppl I care about on signal & now the effort was definitely worth the reward.
Why don’t you feel comfortable on signal? Honestly it’s worked out for the best in my use case bc I have ppl that use android, iOS, windows, Linux & macOS, so it’s great to not have to deal with shit media quality or messages not going through bc of all the different operating systems. It’s E2EE so I’m not too worried about mass surveillance within my signal groups.
Also, iOS back door? I must have missed that. Haven’t seen any news about that.
This maybe be what they are referring to: https://9to5mac.com/2023/12/27/most-sophisticated-iphone-attack-chain-ever-seen/
Signal runs a service. Even if its source code is open source there’s no guarantee that that’s the code running on the server.
I don’t know the protocol, but I am concerned of man in the middle and how safe it is from man in the middle. In this case signal servers must be considered to be man in the middle.
The only system to trust is peer to peer with proven track record of sending encrypted data over public channels.
That’s PGP and Delta Chat utilizing PGP.
