I want to develop routine based on MAC-ID of LAN card to prevent my s/w from piracy.
The program should be able to create encryted text file containing some encryption alogorithm based on MAC-ID of LAN Card. It should be nearly impossible to recover the MAC-ID from the encrypted text file by users. My s/w will then read the text file & un-crypt the key stored it & compare with the actual MAC-ID of LAN Card. ( Do not include code to get Mac-Id from LAN Card as I am already having it)
