Function silc_hmac_make_truncated SYNOPSIS
        void silc_hmac_make_truncated(SilcHmac hmac,
                                      unsigned char *data,
                                      SilcUInt32 data_len,
                                      SilcUInt32 truncated_len,
                                      unsigned char *return_hash);
DESCRIPTION
        Same as the silc_hmac_make except that the returned MAC is
        truncated to the length indicated by the `truncated_len'.  Some
        special applications may need this function.  The `return_hash'
        must be at least the size of `truncated_len'.
NOTES
        For security reasons, one should not truncate to less than half
        of the length of the true MAC lenght.  However, since this routine
        may be used to non-critical applications this allows these dangerous
        truncations.
