This function enumerates the cryptographic providers and their containers to find the private key corresponding to the certificate's public key.
Syntax
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] Bitmask of flags. The following table shows flag values that 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 set to NULL.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 Value
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 following table shows an error that the GetLastError function returns.
The GetLastError function can return NTE_NO_KEY, which indicates there was no container found.
