CRYPT_PROVIDER_REF structure (bcrypt.h)
The CRYPT_PROVIDER_REF structure contains information about a cryptographic interface that a provider supports.
Syntax
typedef struct _CRYPT_PROVIDER_REF {
ULONG dwInterface;
PWSTR pszFunction;
PWSTR pszProvider;
ULONG cProperties;
PCRYPT_PROPERTY_REF *rgpProperties;
PCRYPT_IMAGE_REF pUM;
PCRYPT_IMAGE_REF pKM;
} CRYPT_PROVIDER_REF, *PCRYPT_PROVIDER_REF;
Members
dwInterface
The identifier of the interface that this reference applies to. This will be one of the CNG Interface Identifiers.
pszFunction
A pointer to a null-terminated Unicode string that identifies the algorithm or function that the reference applies to. This can be one of the standard CNG Algorithm Identifiers or the identifier for another registered algorithm.
pszProvider
A pointer to a null-terminated Unicode string that contains the name of the provider.
cProperties
The number of elements in the rgpProperties array. If the algorithm or function has no properties, then this member will be zero.
rgpProperties
An array of CRYPT_PROPERTY_REF structure pointers that contain the properties for this algorithm or function. The cProperties member contains the number of elements in this array.
pUM
A pointer to a CRYPT_IMAGE_REF structure that contains information about the user mode provider module. If this information was not requested or the provider is not registered as a user mode provider, this member will be NULL.
pKM
A pointer to a CRYPT_IMAGE_REF structure that contains information about the kernel mode provider module. If this information was not requested or the provider is not registered as a kernel mode provider, this member will be NULL.
