thank you, it is more and more closer to the python code (read on wiki page I posted in first message, maybe it will help you). Also, funny thing is, when I try your latest code it is terrible slow (but thats OK as you wrote), but I get different hash. I have: 
This is perl, v5.8.4 built for MSWin32-x86-multi-thread
(with 3 registered patches, see perl -V for more detail)

perlhash.pl
00000000ffffffff

When you run this, you get different hash?
