Verifying the Signature of a Release-Signed Driver File
SignTool verify /v /kp DriverFileName.sys
The verify command configures SignTool to verify the signature that is embedded in the driver file DriverFileName.sys.
The /v option configures SignTool to print execution and warning messages.
The /kp option configures SignTool to verify that the signature that is embedded in DriverFileName.sys complies with the kernel-mode code signing policy and the PnP device installation signing requirements for Windows Vista and later versions of Windows.
DriverFileName.sys is the name of the driver file.
For example, the following command verifies that Toaster.sys has a valid embedded signature. In this example, Toaster.sys is in the amd64 subdirectory under the directory in which the command is run.
SignTool verify /kp amd64\toaster.sys
