NAME

gnutls_x509_crt_get_authority_key_gn_serial - API function

SYNOPSIS

#include <gnutls/x509.h>

int gnutls_x509_crt_get_authority_key_gn_serial(gnutls_x509_crt_t cert, unsigned int seq, void * alt, size_t * alt_size, unsigned int * alt_type, void * serial, size_t * serial_size, unsigned int * critical);

ARGUMENTS

gnutls_x509_crt_t cert: should contain a gnutls_x509_crt_t type
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)

DESCRIPTION

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

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.

SINCE

3.0
