CRYPT_GET_TIME_VALID_OBJECT_EXTRA_INFO structure (wincrypt.h)

  • Article

The CRYPT_GET_TIME_VALID_OBJECT_EXTRA_INFO structure contains optional extra information that can be passed to the CryptGetTimeValidObject function in the pExtraInfo parameter.

Syntax

typedef struct _CRYPT_GET_TIME_VALID_OBJECT_EXTRA_INFO {
  DWORD                       cbSize;
  int                         iDeltaCrlIndicator;
  LPFILETIME                  pftCacheResync;
  LPFILETIME                  pLastSyncTime;
  LPFILETIME                  pMaxAgeTime;
  PCERT_REVOCATION_CHAIN_PARA pChainPara;
  PCRYPT_INTEGER_BLOB         pDeltaCrlIndicator;
} CRYPT_GET_TIME_VALID_OBJECT_EXTRA_INFO, *PCRYPT_GET_TIME_VALID_OBJECT_EXTRA_INFO;

Members

cbSize

The size, in bytes, of this structure.

iDeltaCrlIndicator

A value used to compare to the base certificate revocation list (CRL) number. If the base CRL number is less than this value, the caller should attempt to retrieve a newer base CRL.

If the pDeltaCrlIndicator member is non-NULL the value of this member must be 0x7fffffff.Windows Server 2008, Windows Vista, Windows Server 2003 and Windows XP:  Because the pDeltaCrlIndicator member does not exist, the iDeltaCrlIndicator value requirement does not apply.

pftCacheResync

A pointer to a FILETIME structure that governs the use of cached information. Any information cached before this time is considered invalid and new information is retrieved.

pLastSyncTime

A pointer to a FILETIME structure that contains the time of the last synchronization of the data retrieved for the object.

pMaxAgeTime

A pointer to a FILETIME structure that specifies an expiration time of the data retrieved based on the dwMaxAge member of the CRYPTNET_URL_CACHE_RESPONSE_INFO structure.

pChainPara

A pointer to a CERT_REVOCATION_CHAIN_PARA structure that contains the CertGetCertificateChain function parameters used by the caller. The data in this member enables independent online certificate status protocol (OCSP) signer certificate chain verification.

pDeltaCrlIndicator

A pointer to a CRYPT_INTEGER_BLOB structure that contains a CRL with a length of more than 4 bytes. If this member is non-NULL and the iDeltaCrlIndicator member is equal to MAXLONG, then if the base CRL number is less than this value, the caller should attempt to retrieve a newer base CRL.

Windows Server 2008, Windows Vista, Windows Server 2003 and Windows XP:  This member is not supported.

Remarks

All members of the CRYPT_GET_TIME_VALID_OBJECT_EXTRA_INFO structure that do not have a value must be set to zero.
