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 opaque.

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