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 structure
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_REQUESTED_DATA_NOT_AVAILABLE if the extension is not present,
otherwise a negative error value.
