char *silc_hash_babbleprint(SilcHash hash, const unsigned char *data,
                                SilcUInt32 data_len);

    Utility function which can be used to create a textual babbleprint
    out of the data indicated by `data' of length of `data_len' bytes.
    If `hash' is NULL then SHA1 hash function is used automatically.
    The caller must free the returned string.

    The babbleprint is same as fingerprint but encoded in a form which
    makes it easier to pronounce.  When verifying fingerprint for example
    over a phone call, the babbleprint makes it easier to read the
    fingerprint.

    Example output could be:
      xiber-zulad-vubug-noban-puvyc-labac-zonos-gedik-novem-rudog-tyxix
