HASH help

[XtrCt]

hi i got an compiled code wish has some loops and rotate rights in, i know they are compared to a certain module in kernel32.dll but i cant figure out how to make an macro that makes hashed dwords like precisly like that one.

chances are that its not a macro...
its probably a case of the exe being patched after compilation by another tool...

ye why not but thats not really matters i wqant to make an macro that generates alot of hashes and compares them to the original, if it finds one it compares with moudule #2. i havent figured out how but can it be done?

[evlncrn8]

why make it a macro?... why not code some program to do it. it'd probably be much much faster
if it can be done, it'd be damned difficult

What is this compiled code, and why do you want to copy its hashing - some kind of registration-key/encrypted protection?

Anyway, searching for a hash to match, depending on the number of bits used and how long it takes to calculate each one, can take a while, but it's not impossible. More details required :P
