I have, for the first time, submitted a driver for attestation (suing a digicert EV Certificate).The first time it was unsuccessful (due to putting the binaries in the root directory of the .cab file). The second time it was signed without problems. So far so good.
However, the driver did not load as expected and neither did it pass the signtool.exe verification process. After some playing around, I realized that the .sys file had 2 digital signatures. One the Microsoft Signature just singed from the Partner Center. THe other was the Test Signature I used during developement in order to be able to test it. The problem is that the verification tool was only capturing the Test Signature, and thus not passing the verification process (see both pictures below).
So, my question is:
Is there a way to remove the Test Certificate from that .sys file?
I DID rebuild the driver without test signing it, resign it using the EV Certificate and resubmitted it for attestation. But this is another issue, where the signing process has been hanging on the 'Preparation' step every time for the last day, and I do not know what the promblem is cause it's just freezing and not giving me an option to download the report (picture below).
Thanks in acvance for your help
