Api function
#include <gnutls/x509.h>
int gnutls_x509_crt_get_serial(gnutls_x509_crt_t cert, void * result, size_t * result_size);
should contain a gnutls_x509_crt_t structure
The place where the serial number will be copied
Holds the size of the result field.
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 uint8_t.
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value.
