"I want to sell my ebooks and I want to prevent buyers from sharing my ebooks with others."
⇒ A solution: using Hardware-locked keys
The other solutions are online activation and dongle protection.
To open your application, users will have to enter an activation key. If he/she does not have a correct key, the application will not open.
A hardware-locked key is a key delivered to a user that will only work on his/her computer. It won't work on any other machine, so it becomes useless if it is shared with others.
The key is based on a unique system ID that depends on the user's computer hardware.
The key blacklist option lets you block stolen or refunded registration keys.
In HTML Executable, go to Security tab → Certificates page. Then, tick « Create a restricted publication »:
Double-click on « Registered » in the list of certificates. Choose the « Activation Properties » tab, and tick « Use hardware-locked registration keys »:
Compile your project and it is ready for distribution.
You can distribute your ebook. When your customer runs it, a nag screen will pop up, as in the screenshot:
The customer sends you the system ID (highlighted on this screenshot). Then, you can generate his key with HTML Executable.
Open HTML Executable, in Security tab → Certificates page. Click « Make Key »:
Then, enter the name of your customer, the system ID he sent you, and click Generate:
A registration key is generated, you can send it to your customer. Thus, this key will only work on his computer, your ebook will not work in a registered mode on other PCs.
