My .NET exe is signed using signtool. Using this code, I can verify the validity of the certificate itself:
var cert = X509Certificate.CreateFromSignedFile("application.exe");
var cert2 = new X509Certificate2(cert.Handle);
bool valid = cert2.Verify();
However, this only checks the certificate itself, and not the signature of the EXE. Therefore, if the EXE is tampered with, this method doesn't detect it.
How can I check the signature?
