Perl script licensing system?

How to go by implementing such a thing?

[joel2]

I've recently been looking into implementing a bit of partial encryption in a new project that I currently have in development and would like know what method would be best to force an encrypted script to call home and verify an auto-generated license number (once or twice per client - install/admin login). Is there some sort of service offered somewhere on the Internet that already has something similar that could be used with my work?

This is type of thing is a bit new to me and to be honest I'm not quite sure how to go by accomplishing it. Insight on this would be very much welcomed.

HAHA! I laugh because I toyed around with that idea too! :D I never got it off the ground though as it just goes against the whole concept of open source and was concerned with connectivity issues and how it would slow the process down.

Try looking up the curl command.

$response = `curl -d key=value&key2=value url`;

Just offhand I thought a better solution might be to store the key in a local binary file somehow but haven't figured out how to do it without offering up a private pgp key. :-)
