Indeed.

I remember a third year "number theory and cryptography" class at university
(1993/4) when the lecturer got suddenly really excited because some chap had
said he'd developed a proof of Fermat's last theorum. He did point out that
people would be checking it thoroughly to see how rigid a proof it was, and
until then he'd wait and see.

I think this falls into the same category. It'd be a good thing to look at
the potential problems should the Chinese team have mnaged to break SHA1,
but let's not panic yet.

Tom.
