PFN_CRYPT_ENUM_KEYID_PROP callback function (wincrypt.h)

The CRYPT_ENUM_KEYID_PROP callback function is used with the CryptEnumKeyIdentifierProperties function.

Syntax

PFN_CRYPT_ENUM_KEYID_PROP PfnCryptEnumKeyidProp;

BOOL PfnCryptEnumKeyidProp(
  [in]      const CRYPT_HASH_BLOB *pKeyIdentifier,
  [in]      DWORD dwFlags,
  [in]      void *pvReserved,
  [in, out] void *pvArg,
  [in]      DWORD cProp,
  [in]      DWORD *rgdwPropId,
  [in]      void **rgpvData,
  [in]      DWORD *rgcbData
)
{...}

Parameters

[in] pKeyIdentifier

A pointer to a CRYPT_INTEGER_BLOB that contains the key identifier.

[in] dwFlags

Reserved for future use and must be zero.

[in] pvReserved

Reserved for future use. Must be NULL.

[in, out] pvArg

A pointer to an argument that is passed back from the callback function.

[in] cProp

Count of elements in the array of rgdwPropId

[in] rgdwPropId

A pointer to an array of property identifiers. Each entry in the array will be one of the value types listed for in the table for dwPropId in the CryptSetKeyIdentifierProperty function.

[in] rgpvData

A pointer to an array that contains pointers to pvData elements corresponding the rgdwPropId array elements.

For CERT_KEY_PROV_INFO_PROP_ID the rgpvData element points to a CRYPT_KEY_PROV_INFO structure. For all other properties, the rgpvData element points to an array of bytes.

[in] rgcbData

Array of DWORDs that specify the size, in bytes, of corresponding elements in the rgpvData array.

Return value

Returns TRUE if the function succeeds, FALSE if it fails.
