gnutls_x509_crt_get_authority_key_gn_serial - API function


#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);


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)


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.


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.
