CRYPT_INTERFACE_REG structure (bcrypt.h)

  • Article

The CRYPT_INTERFACE_REG structure is used to contain information about the type of interface supported by a CNG provider.

Syntax

typedef struct _CRYPT_INTERFACE_REG {
  ULONG dwInterface;
  ULONG dwFlags;
  ULONG cFunctions;
  PWSTR *rgpszFunctions;
} CRYPT_INTERFACE_REG, *PCRYPT_INTERFACE_REG;

Members

dwInterface

Contains the identifier of the interface type. This can be one of the following values.

Value Meaning
BCRYPT_ASYMMETRIC_ENCRYPTION_INTERFACE
 The provider supports the asymmetric encryption interface.
BCRYPT_CIPHER_INTERFACE
 The provider supports the cipher interface.
BCRYPT_HASH_INTERFACE
 The provider supports the hash interface.
NCRYPT_KEY_STORAGE_INTERFACE
 The provider supports the key storage interface.
BCRYPT_RNG_INTERFACE
 The provider supports the random number generator interface.
NCRYPT_SCHANNEL_INTERFACE
 The provider supports the Schannel interface.
BCRYPT_SECRET_AGREEMENT_INTERFACE
 The provider supports the secret agreement interface.
BCRYPT_SIGNATURE_INTERFACE
 The provider supports the signature interface.

dwFlags

Contains flags that modify the behavior of the interface. This can be one of the following values.

Value Meaning
CRYPT_DOMAIN
 This value is not available for use.
CRYPT_LOCAL
 The interface is registered in the local configuration table.

cFunctions

Contains the number of elements in the rgpszFunctions array.

rgpszFunctions

An array of null-terminated Unicode strings that contains the identifiers of the algorithms that are supported by this interface. These identifiers can be the standard CNG Algorithm Identifiers or the identifiers for other registered algorithms.

Requirements
