Hardware hashes are a common solution used for hardware activation and has been around since Windows XP. It is tougher to crack, but is not impossible with all the keygens out there.Quote:
An easy way in which I'm doing, is to use Hardware-based Serial ID time and HD number. Dai puts a serial valid for 1 Month or 1 year and be happy, if someone steals your program will have to buy a new serial to activate.
That's the way I'm doing.
Also to make that scheme worthwhile you have to sell a LOT of licenses. When there is a relative handful of licensees, it is pretty easy to keep track of all the people that have actually paid you and the ones that didn't.
Hint: This stuff runs in Windows. Don't use the HD volume serial number - use the Windows volume signature instead. It is harder to duplicate.
