Remarks
Cryptography Next Generation (CNG) allows export in any format that the underlying key storage provider (KSP) supports. For example, on Windows Vista,the default KSP (which is MicrosoftSoftwareKeyStorageProvider) only allows export of private keys in the Pkcs8PrivateBlob, EccPrivateBlob, and OpaqueTransportBlob formats. This restriction is controlled by the underlying KSP. If you use a different KSP, other formats may apply.
