NAME
gnutls_x509_crt_get_authority_key_id - API function
SYNOPSIS
#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);
ARGUMENTS
gnutls_x509_crt_t cert
should contain a gnutls_x509_crt_t type
void * id The place where the identifier will be copied
size_t * id_size
Holds the size of the id field.
unsigned int * critical
will be non-zero if the extension is marked as critical
(may be null)
DESCRIPTION
This function will return the X.509v3 certificate authority's key iden-
tifier. This is obtained by the X.509 Authority Key identifier exten-
sion field (2.5.29.35). Note that this function only returns the keyI-
dentifier field of the extension and GNUTLS_E_X509_UNSUPPORTED_EXTEN-
SION, if the extension contains the name and serial number of the cer-
tificate. In that case gnutls_x509_crt_get_authority_key_gn_serial()
may be used.
RETURNS
On success, GNUTLS_E_SUCCESS (0) is returned, GNUTLS_E_RE-
QUESTED_DATA_NOT_AVAILABLE if the extension is not present, otherwise a
negative error value.
