SYNOPSIS

9       #include <gnutls/x509.h>
10
11       int  gnutls_x509_crt_get_serial(gnutls_x509_crt_t  cert, void * result,
12       size_t * result_size);
13

ARGUMENTS

15       gnutls_x509_crt_t cert
16                   should contain a gnutls_x509_crt_t type
17
18       void * result
19                   The place where the serial number will be copied

DESCRIPTION

25       This function will return the X.509 certificate's serial number.   This
26       is  obtained  by the X509 Certificate serialNumber field. Serial is not
27       always a 32 or 64bit number. Some CAs use large serial numbers, thus it
28       may be wise to handle it as something uint8_t.
29

RETURNS

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