What's wrong with Telegram?

[darklajid]

Arguments as far as I'm aware (please correct me where I'm wrong):

- Crypto is 'home made' and - in spite of their crypto-challenges (or, as another school of thought states, related to the fact of trying to use these challenges to appear 'secure') unproven

- End to end encryption isn't the default

I'm looking at this: https://core.telegram.org/techfaq#q-why-are-you-mostly-relyi...

While there seem to be "home made" elements, these are in how they are combining well-known cryptosystems.

So there may well be flaws in how they put it together or in the implementation, it doesn't appear to be a classic case of "home made" snake oil encryption. Also, it seems to be public, not the usual "trade secret" of snake oil.

That's wrong in comparison to Viber/WhatsApp/Skype or just in general?

"Hey look! We invented this novel cryptosystem and, despite it being unproven and not having it validated by anyone, we reckon it's the most secure thing ever!"

Added to that: why don't the just build on XMPP? Why lock users to their servers?

Back in the day, one of the main arguments were that they're "rolling their own crypto", although I don't know how it stands today[0].
