HCRYPTPROV_OR_NCRYPT_KEY_HANDLE

The HCRYPTPROV_OR_NCRYPT_KEY_HANDLE data type is used as a handle to a CryptoAPI cryptographic service provider (CSP) or CNG CSP. This handle must be an HCRYPTPROV handle that has been created by using the CryptAcquireContext function or an NCRYPT_KEY_HANDLE handle that has been created by using the NCryptOpenKey function. New applications should always pass in the NCRYPT_KEY_HANDLE handle to a CNG CSP.

typedef ULONG_PTR HCRYPTPROV_OR_NCRYPT_KEY_HANDLE;

The following functions use the HCRYPTPROV_OR_NCRYPT_KEY_HANDLE data type:

• FreeCryptProvFromCertEx
• CertGetCertificateContextProperty
• CertSetCertificateContextProperty
• CryptAcquireCertificatePrivateKey
