gnutls_x509_crl_get_authority_key_gn_serial — API function


#include <gnutls/x509.h>
int gnutls_x509_crl_get_authority_key_gn_serial( gnutls_x509_crl_t crl,
  unsigned int seq,
  void * alt,
  size_t * alt_size,
  unsigned int * alt_type,
  void * serial,
  size_t * serial_size,
  unsigned int * critical);


gnutls_x509_crl_t crl

should contain a gnutls_x509_crl_t structure

unsigned int seq

specifies the sequence number of the alt name (0 for the first one, 1 for the second etc.)

void * alt

is the place where the alternative name will be copied to

size_t * alt_size

holds the size of alt.

unsigned int * alt_type

holds the type of the alternative name (one of gnutls_x509_subject_alt_name_t).

void * serial

buffer to store the serial number (may be null)

size_t * serial_size

Holds the size of the serial field (may be null)

unsigned int * critical

will be non−zero if the extension is marked as critical (may be null)


This function will return the X.509 authority key identifier when stored as a general name (authorityCertIssuer) and serial number.

Because more than one general names might be stored seq can be used as a counter to request them all until GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE is returned.


Returns 0 on success, or an error code.
