I'm thinking of a function that will generate such a code and put it in a file. Then when the program starts it checks this file and checks the code in there with a code that it generates at that time again based for instance on the current directory and other components unique to that computer. It could be a long string (but what info?) and then take a hash from it and store the hash value.


Better, generate sha1 sum of general machine configuration (i.e. what "set" command returns) and store it on random internet node. You can be sure nobody would get it.

Anyway, it's bad idea. Restrict program usage in license) or any other contract), but don't do such a mess to people who pay your bills.


Well as i said it's more to see when they tampered with the config or the program. It's not a commercial application but it's for inhouse use in the hospital where i work. These people are, to put it mildly, not the most computer savant people around.
It could be handy to avoid me searching for a solution to a problem that arises because of messing with the setup rather than a bug in the code.

Thanks,
