So what's the status?, the MD5 collisions has been confirmed by Eric
Rescorla (taken the type into consideration), the MD4 by David Shaw,
what about Haval and RipeMD?.
I did a test on the RipeMD results and couldn't get the results written.
Anybody else having the same problems?
Any news on Antoine Joux and his attack on SHA-0? how did he create the
collision previously announced on sci.crypt?
