NAME

       gnutls_x509_crt_set_serial - API function

SYNOPSIS

       #include <gnutls/x509.h>

       int gnutls_x509_crt_set_serial(gnutls_x509_crt_t cert, const void * serial, size_t serial_size);

ARGUMENTS

       gnutls_x509_crt_t cert
                   a certificate of type gnutls_x509_crt_t

       const void * serial
                   The serial number

       size_t serial_size
                   Holds the size of the serial field.

DESCRIPTION

       This  function will set the X.509 certificate's serial number.  While the serial number is an integer, it
       is often handled as an opaque field by several CAs. For this reason this function  accepts  any  kind  of
       data  as a serial number. To be consistent with the X.509/PKIX specifications the provided  serial should
       be a big-endian positive number (i.e. its leftmost bit should be zero).

       The size of the serial is restricted to 20 bytes maximum by RFC5280.  This function allows  writing  more
       than 20 bytes but the generated certificates in that case may be rejected by other implementations.

RETURNS

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