Microsoft Kernel-Mode Code Signing Certificates

Kernel-Mode Code Signing Certificates allow you to sign kernel-mode software and device drivers. The x64 editions of Windows Vista and Windows 7 requires all kernel-mode software to be digitally signed by a trusted authority. When you sign your code using a Kernel-Mode Code Signing Certificate, your users will know that it comes from a trusted source (you) and Windows Vista and Windows 7 will inherently trust it. If you don't sign your kernel-mode software and device drivers,your users will see the following message and won't be able to install anything:

By using Kernel-Mode Certificates to sign your software you:

  • Prove your identity to your users
  • Ensure that the software can’t be modified afterwards
  • Allow the kernel-mode software to be installed on x64 Vista and Windows 7 machines
