    What are you asking.
    Are you asking how to make Licence keys.?
    or are you askig how to use licence keys you have made?

    The best way i belive is if you have a program that not going to be mass shiped out.
    I would make specal keys For every program and eather hard code it in to each program so only that one Key works on that one program. Or you can have a list of Keys on the internet in a file. and you can have the program look at that file and see if the key the user putin is one that is on the file online.

    Try this License Key Generator. With this program and library you can create the key and later read it in to validate that the correct key was used.:

    Re: Make Licence Keys

    The best way is to sign your "machine code" ( the NIC, etc) using an algorithm like RSA and then verify the signnature in your app. Give CryptoLicensing a go which implements this (among other scenarios like trials, domain-locking, floating, etc) and is quite easy to use.
