Stuck for a keygen

Post by HarryS »

Hi Guys,
I’m stuck with this software that I think uses its own type of licensing, it give you a customer code and then the generator creates a license key. I am just having trouble working it out, could someone who knows more help me out please?

I have 6 pairs of working license keys below:

Customer 8AFFE-1A516-03E4F licence 3C4C-94A2-72AF-07CE-7520
Customer 8EF7E-18536-4F247 license 3C44-90A2-F3E7-07CE-7530
Customer 88F7E-1E146-45647 license 3C44-D4A2-63AF-07CE-7530
Customer 8C05E-71917-5EA8B license 1824-8092-D7F7-0B42-7737
Customer 8A0DE-73D67-12687 license 182C-8492-56BF-0B42-7727
Customer 8A05E-77D57-54E8B license 1824-C492-47BF-0B42-7737

The codes are from two different computers. Looking at them I’d assume that the license key might be split into different information sections like a machine Id and a vendor code and a time limit and other stuff but I just don’t know that much really.

Without analyzing the serial check function from the target software there's not much you can guess.

I’ve tried to analyse it myself with little luck, I could put the software on here if anyone wants to take a look?

Here is the link for it on mega: https://mega.nz/#!wshQhKLD!ikeiUJAXQbhM ... 7TyOjNY9DX

So far I�ve looked at them with IDA and Olly but I�m only an amateur with this software stuff, Ive always been more of a hardware hacker person instead of software.
