      Why? If someone tries to straight up *CON* people, why is that not enough to run screaming in the opposite direction? Life's too short to do free work, and being subjected to a torrent of abuse and attacks on your reputation by the CEO is the only reward for analysing telegram

      Anyway there's more here than I can unpack in tweets, and I need to go sleep. I understand your frustration with the lack of details, I think I do at least. I'll attempt to write longer about it in the morning :)

      I'm excited to see it. For reals. I think it's useful to avoid freely swapping between "incompetence" and "malice" when analyzing what people are doing 😀

      I need to apologise twice. One for this being 4,500 words and very rambly. I hope it still makes some kind of sense. Two for this containing nothing that you asked for ;) but hopefully it explains why you aren't getting that. https://txt.fyi/+/9c1ca7c5/

      IMPORTANT CAVEAT: This is just like, my opinion, man. I'm not a cryptographer, I'm a security engineer, and I've just absorbed information about crypto from HN and IRC. Everything I say could be completely wrong. I haven't yet gotten peer review on this.

      I'm sad that anything I said made it sound like I thought crypto wasn't very very hard or that it's reasonable to assume a particular new crypto algorithm works.

      "I know it looks like we're being pedantic or even cliquey, but what's really happening is they've spotted a fatal flaw in the crypto." I don't feel anyone is being cliquey and I interpreted the first round of critiques in exactly this way.

      I'm finding your post here problematic in much the same way as I was originally bothered by but there's more signal here (no pun intended).

      "If a 12 year old comes into your IRC channel with their homegrown encryption algorithm, no-one's going to care when you break it, because no one thought it was sound in the first place." This is not a 12 yo. It's one of the most popular chat programs in the world.

      And given that 1. people were interested in showing flaws in MTProto1, and 2. they cared enough to attempt to fix them in MTProto2, it seems like there's a reason to check MTProto2 and I bet papers would be accepted at conferences.

          (I also understood the part about there being a large gap between flaw and vuln, also see Spectre)

          Hey, so like... please don't infer too much about how I think about you precisely from this. You were asleep while I wrote it, I couldn't sound out your views, so it's a more general-audience argument :)

          Fair enough. I either don't like how you characterized my views or don't think you did such a good job of debunking them :p

          I think the difference between our mental models comes down to this: You're acting like telegram is a crank 12 year old flying rockets based on flat Earth theory so they can be safely ignored. I think of them (accurately) as one of the top chat programs in the world.

          Both can be true! 1) deploying crank crypto to millions of people doesn't stop it being crank crypto 2) how many of those millions even use the crypto? it's off by default. Can't be turned on for group messages. Most Telegram chats are going plaintext.

          So if you want to play the "millions of users" card, well, they're using plaintext, that's the end of the discussion. No crypto conference is going to accept your submission on breaking that! * by plaintext I mean "client-server encryption" which is tbh VERY SLOPPY on my part

          You should strive to avoid sloppiness that serves to add rhetorical heft to a weaker argument ;)

          The incentives to debunk a 12 year old on an IRC channel are low. The incentives to find flaws in software used by hundreds of millions of people is demonstrably huge.
