NAME         top

       gnutls_x509_crt_set_serial - API function

SYNOPSIS         top

       #include <gnutls/x509.h>

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

ARGUMENTS         top

       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         top

       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

       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

RETURNS         top

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