Synopsis

#include <gnutls/x509.h>

DESCRIPTION

This function will return the X.509 certificate's serial number. This is obtained by the X509 Certificate serialNumber field. Serial is not always a 32 or 64bit number. Some CAs use large serial numbers, thus it may be wise to handle it as something opaque.

On success, GNUTLS_E_SUCCESS is returned, otherwise a negative error value.
