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?
