CryptFindCertificateKeyProvInfo

This function enumerates the cryptographic providers and their containers to find the private key corresponding to the certificate's public key.

BOOL WINAPI CryptFindCertificateKeyProvInfo(
PCCERT_CONTEXT pCert,
DWORD dwFlags,
void *pvReserved
);

Parameters

• pCert
  [in] Pointer to the CERT_CONTEXT structure of the certificate to use when exporting public key information.

• dwFlags
  [in] The following flag values are defined.

  Value	Description
  CRYPT_FIND_USER_KEYSET_FLAG	Restricts the search to the user container.
  CRYPT_FIND_MACHINE_KEYSET_FLAG	Restricts the search to the machine container.

  If no flag value is specified, both the user and the machine containers are searched.

• pvReserved
  [in] Reserved for future use and must be NULL.

  Note This function enumerates the cryptographic providers and their containers to find the private key corresponding to the certificate's public key. For a match, the function updates the certificate's CERT_KEY_PROV_INFO_PROP_ID property. If the CERT_KEY_PROV_INFO_PROP_ID is already set, it is checked to see if it matches the provider's public key. For a match, the function skips the previously mentioned enumeration.

Return Values

Returns TRUE if the function finds a private key corresponding to the certificate's public key within a searched container.

Returns FALSE if the function fails to find a container or a private key within a container.

The GetLastError function returns the following error.
