We have a code that creates a new X509Certificate2 and it works perfectly in development environment. The same code crashes in IIS hosting to the following stack trace:

An unhandled exception was thrown by the application.
System.Security.Cryptography.CryptographicException: Cannot find the requested object.
     at System.Security.Cryptography.CryptographicException.ThrowCryptographicException(Int32 hr)
     at System.Security.Cryptography.X509Certificates.X509Utils._QueryCertBlobType(Byte[] rawData)
     at System.Security.Cryptography.X509Certificates.X509Certificate.LoadCertificateFromBlob(Byte[] rawData, Object password, X509KeyStorageFlags keyStorageFlags)
     at System.Security.Cryptography.X509Certificates.X509Certificate2..ctor(Byte[] rawData)

At first I thought we provide empty cert to the constructor, but looking at the source code tells me that there should be a bit different error message if the rawData would be NULL or empty.

Edit 1
I managed to get pass the problem by installing the certificate manually to the server and then just getting it from the storage instead of creating it on the fly. Still don't know why the creating fails.

Could it be this: http://stackoverflow.com/a/10048789/20195 – Pasi Savolainen Jun 02 '16 at 12:20
Tested and not helping so I guess it's not that. – Antti Simonen Jun 02 '16 at 12:48
Did you try to pass password directly into X509Certificate2 ctor? – Set Jun 02 '16 at 14:13
Yes, I've tried it and also setting the flags that were suggested in other threads. None of those help. – Antti Simonen Jun 02 '16 at 17:27
