serial numbers on standalones

[Peter Bogdanoff]

Richard,

You could...

1. If you have a limited number of installations, you could store internally a list of keys, then issue one of them to each user. If it matches one of the internal list, it's good.

2. You could have a separate program with an algorithm that creates keys in a particular pattern. Those are the keys issued to users. When a key is entered by the user, the program decodes the key to see if it matches the algorithm thus a valid sequence. I've used something as simple as a test to see if a letter or number is in a particular position, but it could be much more complex.

These don't allow for a user name. And of course, none of these eliminates the reuse of a key by someone else. For that you would need an Internet/server system.
