Security and Trial Options For Ebooks and Apps





HTML Executable is an unmatched tool in providing powerful security features for your eBooks and digital publications. It offers an array of options that can be adapted to fit your specific needs, enhancing the protection of your digital content. These features can even be combined for superior control and security.


📹 Consider viewing our video tutorial on how to convert an eBook into an evaluation version and understand how to select which pages should be accessible in this trial. For instance, if you aim to offer a trial or evaluation version of your eBook on your website for public download, you might want to lock certain crucial pages. You can freely offer the first 3 chapters to your end users, and when they purchase your eBook, send them a key to unlock the remaining chapters.


Here are the different options you have with HTML Executable to enhance your eBook's security:


Single Computer Accessibility: If you desire for your eBook to be accessible on one computer only, making sharing of your production impossible:

o👉 Use hardware-locked keys with the Certificates page


Remote eBook Management: If you wish to remotely manage your eBook, lock/unlock your publication, control the number of activations of your eBook:

o👉 Use online activation with the Certificates page
