       const Shisa_key * hint
                   Pointer to a Shisa key structure with hints on matching criteria  for  relevant  keys.   NULL
                   matches all keys.

       Shisa_key *** keys
                   Returned pointer to a newly allocated array of Shisa key structures.

       size_t * nkeys

       Iterates  through the set of keys belonging to PRINCIPAL@REALM, as selected by principal and realm.  Then
       extracts any keys that match the criteria in hint.

       Not all elements of hint need to be filled in.  Set only the fields you are interested in.  For  example,
       if  you  want  to extract all keys of etype 3, i.e., DES-CBC-MD5, then set the field key->etype to 3, and
       all other fields to zero.
