Can't sign kernel drivers for Windows 11 & 10
Hi,
We recently purchased an EV certificate to sign our software kernel driver, however, when trying to load it in Windows 10 it fails with code 0x800B010C aka CERT_E_REVOKED - A certificate was explicitly revoked by its issuer.
We checked the driver with "signtool verify /v /all /pa" as suggested by our cert provider and everything is still valid.
We followed these instructions https://docs.microsoft.com/en-us/windows-hardware/drivers/dashboard/attestation-signing-a-kernel-driver-for-public-release
We've also tried contacting Microsoft's dev support by MS closed it down recently and they're not replying anymore...
Any help would be appreciated,
A.
- For us, the issue was that we had "Perform test-signing" ticked on the UI when uploading the driver for signing.
- Yes, I met the same issue.
Did you manage to resolve this? We are facing the same problem with a Sectigo EV certificate. Was your's from Sectigo or some other provider?
