gnutls_x509_crt_get_authority_key_id — API function
#include <gnutls/x509.h>
int
gnutls_x509_crt_get_authority_key_id( |
gnutls_x509_crt_t cert, |
| void * id, | |
| size_t * id_size, | |
unsigned int * critical); |
should contain a gnutls_x509_crt_t structure
The place where the identifier will be copied
Holds the size of the id field.
will be non−zero if the extension is marked as critical (may be null)
This function will return the X.509v3 certificate
authority's key identifier. This is obtained by the X.509
Authority Key identifier extension field (2.5.29.35). Note
that this function only returns the keyIdentifier field of
the extension and GNUTLS_E_X509_UNSUPPORTED_EXTENSION, if
the extension contains the name and serial number of the
certificate. In that case gnutls_x509_crt_get_authority_key_gn_serial()
may be used.
On success, GNUTLS_E_SUCCESS (0) is returned, GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE if the extension is not present, otherwise a negative error value.
