Detailed Description

This class represents a callback object for Foxit DRM decryption. If user wants to use their own Foxit DRM security callback, user should inherit this callback class and implement the pure virtual functions (as callback functions), and then register their own Foxit DRM security callback object to Foxit PDF SDK by function FSDK.Library.RegisterSecurityCallback with filter "FoxitDRM". Function FSDK.Library.UnregisterSecurityCallback can be called to unregister the security callback object with the registered filter name.
