Digitally Signed Kernel-mode Drivers


We appreciate your feedback. The result is that any computer checking the signature will look for the GlobalSign root R1 certificate instead of looking for the GlobalSign root R3 certificate. On an internet-disconnected Windows Vista computer, unfortunately neither of the certificates were available.

Alternatively, you could distribute the executable unsigned. Most rootkits I've dealt with intercept file-system calls to hide the files and the signature of the modified file. I think the best practice for the version number is to start it at 1.0.0, and whenever you edit the file for any reason you should increase the version number and Another important concept to understand is the hash function, which is also called a digest algorithm or thumbprint algorithm. https://www.digicert.com/code-signing/kernel-mode-certificates.htm
