DESCRIPTION
       Tspi_ChangeAuthAsym  changes the authorization data (secret) of an entity (object) utilizing the asymmetric change protocol and assigns the
       object to the policy object. All classes using secrets provide this method for changing their authorization data.  This method changes  the
       authorization data of an object ensuring that the parent of the object does not get knowledge of the new secret.

PARAMETERS
   hObjectToChange
       Handle of the object the authorization data should be changed.

   hParentObject
       Handle of the parent object wrapping the object addressed by hObjectToChange.

   hIdentKey
       Handle of the identity key object required to proof the internally created temporary key.

   hNewPolicy
       Handle of the policy object providing the new authorization data.

RETURN CODES
       Tspi_ChangeAuthAsym returns TSS_SUCCESS on success, otherwise one of the following values are returned:

       TSS_E_INVALID_HANDLE - Either hObjectToChange, hParentObject, or hIdentKey is an invalid handle.

       TSS_E_INTERNAL_ERROR - An error occurred internal to the TSS.
