Accessing and Protecting Data Files

When you use Sentinel LDK Envelope to protect a Windows application, you can add the capability to access and write data to protected data files.

A given protected application can be equipped with either of two modes of data file protection:

>Version 1 - This is appropriate for general-purpose data files. In this mode, the contents of the data files are encrypted. The data files can only be accessed by applications that have been protected with the vendor's unique Vendor Code and that have been provided with a specific encryption key.

>Version 2 - This is appropriate for important data files that you want to license separately, such as training video files and courseware. In this mode, the data files are encrypted and protected by assigning a Feature ID. Only users that purchase the specific license required for the files are able to access the files.

For a complete description of the available data protection options, see Protecting Data Files.
