To create or open a key, you must first obtain a provider handle. NCryptOpenStorageProvider function (ncrypt.h) - Win32 apps
MS_SMART_CARD_KEY_STORAGE_PROVIDER : Used for smart card operations. If set to NULL , the system loads the default KSP.
: A Unicode string identifying the KSP. Common values include:
SECURITY_STATUS NCryptOpenStorageProvider( [out] NCRYPT_PROV_HANDLE *phProvider, [in, optional] LPCWSTR pszProviderName, [in] DWORD dwFlags ); Use code with caution.
