History
PADL is a originaly written in 2005 by Oliver Lillie under older PHP4, parked on PHPCLASSES site. You can find the original code as part as this distribution or directelly in PHP-Generate-PHP-application-license-keys.
You can see a quote about:
There are several solutions to help developers protecting the PHP software
of applications that they want to sell.
Usually the developers provide license keys with their software
that include information about the licensed code, enabled features,
authorized configuration of the environment on which it is being installed.
This helps the developers to limit the scope of usage of their
software according to the type of software license that their clients purchase.
This way the developers can use the same software distribution
for different configurations and prices and even trial versions.
This class provides a means to generate license keys that include encrypted
information about the clients PHP environment and even a way to send the keys
to the developers site so they can capture the client features and generate
upgraded keys that can enable more features for clients that pay the upgrade price.
