i am trying to crack a program using ollydbg.
in the older protections i found the serial in the stack window while placing a breakpoint on getdlgitemtxtA.the serial was in the stack in plain ascii text, so there was no problem in finding the serial.
but in the new version , although the protection remains the same the serial seems to be hardcoded in memory.no ascii texts are displayed in the stack window but addresses are placed instead of serials (in the older versions);

for eg:
in older versions:
0012345 : [memory address] "qasadafaf" (the serial)

but in new version:
0012345: [memory address] program name.some memory address

when i go to the memory address there r som characters but serial is hardcoded;



is there any way of finding the serial?

If it does indeed use a hardcoded serial, look for comparison instructions.

Otherwise it may not be a hardcoded serial at all, just an algorithm.

Hi,

maybe you know see the addresses which are pointer to the serials. First i would try so look what is "beyond" the addresses at the stack where formerly the hardcoded serials are lying
