As I recall, Telegram put up bounties for people actually demonstrating exploits in its encryption. Have any of these cryptography experts actually shown exploits?
telegram put up bounties relating to specific properties of their encryption, yes but there’s more to private messaging than just encryption… for example afaik it’s trivial to do things like replay attacks
their encryption may not be flawed, but they failed to design an algorithm that protects against the wide array of modern attacks, as they are mathematicians; not security experts. they understood the maths, but not the wider scope of implementation
a good example of these is linked down thread about MLS
the telegram bounties afaik only cover 1 security property
But can you provide an example of an actual flaw being demonstrated by anybody with or without a bounty?
i neither have the time nor inclination to research to that degree - i’m merely saying that the bounties prove very little, and change nothing about how people should treat non-standard protocols and algorithms. in fact, the lack of substance is proof that they don’t fully understand the scope of what’s required in the field of security
And I'm saying that despite people constantly throwing shade on the protocol, nobody has actually showed any flaws in it over many years. The whole dogma that non-standard protocols and algorithms should be shunned out of principle is just that. Meanwhile, plenty of exploits have been found in standard protocols. Not only that there are known cases where US security agencies introduced exploits into popular protocols. https://www.theverge.com/2013/12/20/5231006/nsa-paid-10-million-for-a-back-door-into-rsa-encryption-according-to
