Software Copy Protection and License Control
NActKey provides Microsoft Windows developers a strong yet simple
and cost-effective solution for protecting software against piracy.
License activation through NActKey can be accomplished automatically
over the Internet, so the activation process is practically transparent
to end users. NActKey also supports manual activation for end users
who don’t have an Internet connection.
The NActKey Client (ActiveX DLL) features a built-in activation dialog,
so implementing NActKey copy protection into your software takes just
a few lines of code!
| How Software Is Activated Using NActKey |
- The end user enters the serial number provided with their
installation media into the NActKey Client’s built-in activation
dialog (optionally, you can create your own activation dialog).
Serial numbers are generated using the
online NActKey Developer Console.
- The NActKey Client generates a request code (hardware signature),
which uniquely identifies the computer running your application,
and an activation key, which uniquely identifies your application
as installed on the system. Since these
signatures are hardware based, they WILL NOT change if the drive
is reformatted but WILL change if the drive is cloned.
- The NActKey Client sends the serial number and activation
key to the NActKey Activation Server. If everything is in order,
the server authorizes the activation and records the transaction
in the activation database.
- Your application saves the activation key to the local system
(file, registry, etc.). It is not necessary
to encrypt or hide the activation key, because it is useless on
any other system.
- Each time your application loads, it queries the NActKey Client
and compares the activation key it provides to the one saved on
the system. If they match, your application knows it has been
activated and can proceed accordingly.
