• Create and manage registration keys (a.k.a serial numbers) for users. A registration key allows an end user to turn your ebook from the Trial to a Registered version.
  
  
• Or unlock registered editions with online activation from your server. The activation kit allows you to install required files on your server and configure options.
   
• Registration keys can be created online or in mass: we provide scripts in php, C#, Pascal, VB... to all users of the Professional/Commercial edition. You can then integrate these scripts into your own sales system. Registration keys may also be manually created with HTML Executable.
  
  
• Easy Integration with PayPal: see the HTML Executable PayPal Kit. Deliver keys to customers by email immediately after successful orders with PayPal. It comes with ready-to-use script files and a complete tutorial with screenshots.
  
  
• Accept refunds from customers thanks to the Deactivation feature that uninstalls a registration key definitively from a computer and gives your customers a refund code that you can verify in order to refund them.
  
• Integrated DRM (Digital Rights Management): no external expensive solution is required.
  
  
• Show customizable nag screens at different times:

• Create different editions of your eBooks: thanks to certificates, you can make different registered versions (Lite, Premium, Commercial, Professional...).

• You can select which HTML page(s) should be displayed only after user registration or depending on which edition the user purchased!
   
• You can put a link to your order page directly in the nag screen (what you want).
  
• Use the key blacklist option for stolen or refunded registration keys.
  
  
• Create hardware-locked registration keys: the key you send to an user will only work on his/her computer. This will reduce piracy possibilities.
  
  
• Compatible with the other security options.
