gnutls_x509_crt_get_serial - Man Page

API function


#include <gnutls/x509.h>

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


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.


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.
