Specifies that the digital signature of the binary image must be checked at load time.


In the header of the DLL file or executable file, this option sets a flag that requires a digital signature check by the memory manager to load the image in Windows. Versions of Windows prior to Windows Vista ignore this flag. This option must be set for 64-bit DLLs that implement kernel-mode code, and is recommended for all device drivers. For more information, see Kernel-Mode Code Signing Walkthrough on the MSDN website.
