Api function

Usage

#include <gnutls/x509.h>

int gnutls_x509_crt_get_serial(gnutls_x509_crt_t cert, void * result, size_t * result_size);

Arguments

gnutls_x509_crt_t cert

should contain a gnutls_x509_crt_t type

void * result

The place where the serial number will be copied

size_t * result_size

Holds the size of the result field.

Overview

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.

Returns

On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value.
