CRYPTCATATTRIBUTE structure (mscat.h)

[The CRYPTCATATTRIBUTE structure is available for use in the operating systems specified in the Requirements section. It may be altered or unavailable in subsequent versions.]

The CRYPTCATATTRIBUTE structure defines a catalog attribute. This structure is used by the CryptCATEnumerateAttr and CryptCATEnumerateCatAttr functions.

Syntax

typedef struct CRYPTCATATTRIBUTE_ {
  DWORD  cbStruct;
  LPWSTR pwszReferenceTag;
  DWORD  dwAttrTypeAndAction;
  DWORD  cbValue;
  BYTE   *pbValue;
  DWORD  dwReserved;
} CRYPTCATATTRIBUTE;

Members

cbStruct

The size, in bytes, of this structure.

pwszReferenceTag

A pointer to a null-terminated string that contains the reference tag value.

dwAttrTypeAndAction

Bitwise combination of the following flags.

Value	Meaning
CRYPTCAT_ATTR_AUTHENTICATED 0x10000000	The attribute is authenticated.
CRYPTCAT_ATTR_UNAUTHENTICATED 0x20000000	The attribute is unauthenticated.
CRYPTCAT_ATTR_NAMEASCII 0x00000001	The attribute is an ASCII string.
CRYPTCAT_ATTR_NAMEOBJID 0x00000002	The attribute is a cryptographic object identifier (OID).
CRYPTCAT_ATTR_DATAASCII 0x00010000	The attribute contains simple ASCII characters that should not be decoded.
CRYPTCAT_ATTR_DATABASE64 0x00020000	The attribute is in base 64 format.
CRYPTCAT_ATTR_DATAREPLACE 0x00040000	The attribute replaces the value for an existing attribute.

cbValue

Number of bytes used by pbValue.

pbValue

A pointer to the encoded bytes.

dwReserved

Reserved; do not use.
