Beid : C# CryptoAcquireFailed Error=80090019

问题

I'm using Belgian ID card to sign some stuff. The example sign_csp in the SDK failed with this error : CryptoAcquireFailed. Error=80090019.

//Get a context
if (!CryptAcquireContext(out hprov, container, provider, PROV_RSA_FULL, CRYPT_VERIFYCONTEXT))
{
   MessageBox.Show("CryptAcquireContext failed.\n\n(Error=" + Marshal.GetLastWin32Error().ToString("x") + ")"); 
   return;
}

provider = "Belgium Identity Card CSP"

I'm on Windows 7 64 bit. The program is built for x86.

Thanks!

回答1:

Have you installed the CSP correctly?

Verify that you have the following key in the registry:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography\Defaults\Provider\Belgium Identity Card CSP

and that the Image Path entry contains the correct path to the CSP-dll.
