laie makes it sound like they found two things (free-start collision attack and circular hash attack).
I agree the free-start part isn't very interesting but I don't think we have enough information to confirm or dismiss whether the circular hash attack part is novel.
- simias 9y agoExtraordinary claims require extraordinary evidence, I think it's fair to dismiss those claims until they're capable of coming with a better justification than "I developed an entirely new type of cryptanalysis theory to achieve this."
- jey 9y agoCould you unpack "circular hash attack"? Googling was not very helpful.
- amenghra 9y ago"circular hash attack" left me confused and waiting to hear the full story. I totally agree with "Extraordinary claims require extraordinary evidence".

Let me assure you: there is nothing novel here. There is no vulnerability. You want to start from a place of skepticism with these things, not a place of, "Well we don't have enough information to say it's not true..."
