X509Certificate Constructor Exception

Question

//    cert.CertificatePKCS12 is a byte[] with the certificate.

var certificate = new X509Certificate(cert.CertificatePKCS12, \"SomePassw         


        

Answer 1

I had trouble on Windows 2012 Server R2 where my application could not load certificates for a PFX on disk. Things would work fine running my app as admin, and the exception said Access Denied so it had to be a permissions issue. I tried some of the above advice, but I still had the problem. I found that specifying the following flags as the third parameter of the cert constructor did the trick for me:

 X509KeyStorageFlags.UserKeySet | 
 X509KeyStorageFlags.PersistKeySet | 
 X509KeyStorageFlags.Exportable
