CertAddCRLContextToStore function

The CertAddCRLContextToStore function adds a certificate revocation list (CRL) context to the specified certificate store.

Syntax

BOOL CertAddCRLContextToStore(
  HCERTSTORE    hCertStore,
  PCCRL_CONTEXT pCrlContext,
  DWORD         dwAddDisposition,
  PCCRL_CONTEXT *ppStoreContext
);

Parameters

hCertStore

Handle of a certificate store.

pCrlContext

A pointer to the CRL_CONTEXT structure to be added.

dwAddDisposition

Specifies the action to take if a matching CRL or a link to a matching CRL already exists in the store. Currently defined disposition values and their uses are as follows.

Value Meaning
CERT_STORE_ADD_ALWAYS
Makes no check for an existing matching CRL or link to a matching CRL. A new CRL is always added to the store. This can lead to duplicates in a store.
CERT_STORE_ADD_NEW
If a matching CRL or a link to a matching CRL exists, the operation fails. GetLastError returns the CRYPT_E_EXISTS code.
CERT_STORE_ADD_NEWER
If a matching CRL or a link to a matching CRL exists, the function compares the ThisUpdate times on the CRLs. If the existing CRL has a ThisUpdate time less than the ThisUpdate time on the new CRL, the old CRL or link is replaced just as with CERT_STORE_ADD_REPLACE_EXISTING. If the existing CRL has a ThisUpdate time greater than or equal to the ThisUpdate time on the CRL to be added, the function fails with GetLastError returning the CRYPT_E_EXISTS code.

If a matching CRL or a link to a matching CRL is not found in the store, a new CRL is added to the store.

CERT_STORE_ADD_NEWER_INHERIT_PROPERTIES
The action is the same as for CERT_STORE_ADD_NEWER, except that if an older CRL is replaced, the properties of the older CRL are incorporated into the replacement CRL.
CERT_STORE_ADD_REPLACE_EXISTING
If a matching CRL or a link to a matching CRL exists, the existing CRL or link is deleted and a new CRL is created and added to the store. If a matching CRL or a link to a matching CRL does not exist, one is added.
CERT_STORE_ADD_REPLACE_EXISTING_INHERIT_PROPERTIES
If a matching CRL exists in the store, the existing context is deleted before creating and adding the new context. The added context inherits properties from the existing CRL.
CERT_STORE_ADD_USE_EXISTING
If a matching CRL or a link to a matching CRL exists, that existing CRL is used and properties from the new CRL are added. The function does not fail, but no new CRL is added. If ppCertContext is not NULL, the existing context is duplicated.

If a matching CRL or a link to a matching CRL does not exist, a new CRL is added.

ppStoreContext

A pointer to a pointer to the decoded CRL context. This is an optional parameter and can be NULL, indicating that the calling application does not require a copy of the added or existing CRL. If a copy is made, that context must be freed by using CertFreeCRLContext.

Return Value

If the function succeeds, the return value is TRUE.

If the function fails, the return value is FALSE. Errors from the called functions CertAddEncodedCRLToStore and CertSetCRLContextProperty can be propagated to this function.

For extended error information, call GetLastError. Some possible error codes follow.

Return code Description
CRYPT_E_EXISTS
This error is returned if CERT_STORE_ADD_NEW is set and the CRL already exists in the store or if CERT_STORE_ADD_NEWER is set and a CRL exists in the store with a ThisUpdate date greater than or equal to the ThisUpdate date on the CRL to be added.
E_INVALIDARG
The dwAddDisposition parameter specified a disposition value that is not valid.

Remarks

The CRL context is not duplicated using CertDuplicateCRLContext. Instead, a new copy is created and added to the store. In addition to copying the encoded CRL, the function copies the context's properties.

To remove the CRL context from the certificate store, use the CertDeleteCRLFromStore function.
