I am writting some keygenerators for some programs that I have aquired, and reversed the algorithms for the serial. The program presents some numbers "3355796438" and calls it "Machine Code". I have looked high and low for where these numbers come from. The only thing I can think of it is used for quening in messaging to identify the computer being used. Can anyone point me in the correct direction? Please.

Could come from many different places.

For example :

Your Network cards MAC address (unique).
IDE harddrive serial number (unique).
Master Boot record serial number.

etc.etc.

Do a search on the net for Machine ID or CPU ID.
You should find references to many possibilities.

Thank you for your reply I will do that.

What you are talking about is most likely a "hardware ID", and it can be implemented in a number of ways. Basically you can say that it's a hash of one or more system-dependent properties (like e.g. the ones tgodd mention above). Your best bet is to locate the procedure in the program that calculates this number and then rip that algo.

Thank you for the information. I will revist my little friends and find out how they are coming up with that number.

MAC address, HDD serial, MBR serial - not unique!
I made different, if me need.

Yes ...
The tools are out there to do this.
However some of these things were not meant to be changed.

Every machine 'IS' truely unique.
You could even create a hash on the entire registry so the registry
would have to be identical at the time of installation.

Hardware Could be different.

There are just to many things to say :

"I made different, if me need."


In reality it is not as simple as that.

Hi!

"There are just to many things to say :"

""I made different, if me need.""


Hash in registry - only for MAC address.
HDD and MBR - directl by small program.
