More Hash Functions Broken

Following up on this rumor from earlier today.

There is still no confirmation out there of the break in SHA-1, but this preprint, which went up today, reports collisions in MD4, MD5, HAVAL-128 and RIPEMD, all achieved with very little CPU time. That pretty much covers all the cryptographic hash functions in use.

It feels as though once someone found the right thread to pull on, the whole sweater started to unravel.
