How to check a signed DLL

Question

I created my own certificate for signing a DLL. When I load this DLL into my C ++ application, I can check if the code signing certificate is valid using the WinVerifyTrust api.

But I cannot find a way to detect that the DLL was signed by one of my certificates. Even using the CryptQueryObject api, I do not find useful information.

Does anyone have an idea on how to do this? Or is this event possible?

thanks

Answer 1

CryptVerifyCertificateSignature is not what you want?
