Also, can we backup our messages yet on iOS?
If people insist on me using Signal to communicate with them, these people probably have far-too-inflexible values concerning privacy for me to bother anyway.
It's entirely possible to sway your group of friends from Whatsapp to Signal. I've done it myself. I'm not saying you should. I'm just saying your comment is logically self refuting.

* It really seems like matrix is superior in every way to both of these.
It is much easier to backup, restore, and change devices (one of the chief complaints about both Signal and WhatsApp of course), has more cognizable (and yet less intrusive!) information displayed about the cryptological situation for any given chat, and is much more flexible. Also, it has clients which are just as stable (at least that's my experience with Element on both linux and android).
My only complaint about the current generation of Element clients is that there is, unless I'm missing something, no way to globally search across all saved chats. Which is really a blocker sometimes when using it for work.
But yeah, at the risk of sounding like I'm blinding emitting the cliche response of "why no my favorite app?!", I really think it's time to ask why we're always using and recommending signal rather than matrix.
People are already too deeply invested in convincing people to use Signal and they can't easily amend this choice because Signal is not a Matrix client -> sunk cost fallacy
That’s not a reasonable assumption IMO. The report API most likely takes the message your phone has decrypted (so that you can read it) and sends it over to Meta. This doesn’t break end-to-end encryption. Neither does me copying the message from a friend and posting it on Twitter.
What does E2EE potentially give you? A promise, which does not involve trusting the service provider, that messages can only read by the recipient.
What does making the app closed source take from you? The freedom of requiring trusting the service provider = facebook
It does change the requirement of collection.
It's no longer "Well all this data is rolling in, what shall we do with it".
It's "Hey, if we commit THREE BILLION FELONIES of backdooring our every users' encryption, we can access all that data".
Surely you realize that's a leap.
The world will neither like the same messenger nor will it make the switch at the same time.
So you need to give people the choice to choose an app they like without needing to convince their social network to do the same (potentially x-times, because you are not their only contact).
This is why you should switch to a messaging standard such as Matrix, not a centralized messenger.
Sure, but for all we know it is a wholly owned subsidiary of the CIA. See Crypto AG[1].
>...if we all start to do this, it will mean more people are on Signal, hopefully gradually making it more attractive to move across!
Signal is controlled by a single entity and is not federated. So it is only a matter of time before things fall apart. So it is not a good idea to promote it as some sort of messaging standard.
I mean, Signal is OK and is a fine replacement for Whatsapp, but all these rabid expressions of Signal fandom are starting to get annoying.
This is such a sad propaganda tactic.
Signal's client is 100% open source. The Android client has reproducible builds. You can verify yourself the cryptographic primitives are used, and function correctly with test vectors.
E.g. Here's those for the key exchange X25519 https://datatracker.ietf.org/doc/html/rfc7748
Here's the test vectors for AES https://csrc.nist.gov/CSRC/media/Projects/Cryptographic-Algo...
>Signal is controlled by a single entity and is not federated. So it is only a matter of time before things fall apart.
It's backed by the Signal foundation, donations, and it doesn't suffer from bike shedding bigger federated systems struggle with. Take OpenPGP v5 fingerprints that are still, 15 years after SHA-1 was considered weak, not available in gpg, if at all. Federated systems and standards bodies with disengaged management are easy to subvert from the inside with tactics like these https://www.404media.co/declassified-cia-guide-to-sabotaging...
>So it is not a good idea to promote it as some sort of messaging standard.
The protocol isn't a standard, but its security properties are the gold standard. That's why it's being used in most networked TCB apps that take their security as serious as they can.
You're also not proposing a solution so I take it you're advocating for Matrix.
Assuming you mean V5 PGP keys. There are 2 proposed key formats due to the standards fork which actually supports your argument. But since there is no actual weakness, it is safe to just stick with what people have been using since forever.
SHA-1 is only broken for collisions. Fingerprints do not require collision resistance. PGP used to use only 32 bits of the SHA-1 hash for the short form of the fingerprint. That became problematic because they could be straight up forged from an existing fingerprint so now 64 bits are used. Such fingerprints are trivially collideable simply because of the length. But, again, that is not an issue. You have to look at the security of the system when evaluating things like this, not just looking for particular primitives.
>You're also not proposing a solution so I take it you're advocating for Matrix.
Yeah, fans tend to assume that everyone is a fan of something... Just saying...
That's what they're literally there for. To avoid situation where someone generates a key with matching fingerprint, and the person importing the key doesn't detect it's a forgery.
>Yeah, fans tend to assume that everyone is a fan of something... Just saying...
Yeah I'm a fan of adequate computational headroom where it doesn't cost anything.
Signal is the best messaging app in almost every meaningfully measurable way. (Source: me.) People's gripes seem mostly to be around "But my barber still uses WhatsApp"... Yeah, it's called the network effect. So do your part and go promote one of the best "free" apps we all have the privilege of using, before even this option is removed from us.
