        storage stream to another without decryption. It is not reccomended to
        use this method outside of storage implementation since different
        storages implementation could have different encryption format. If the

        The difference of this method from the previous one is that it handles
        only encrypted streams. The contents of returned by these methods
        streams can differ for the same entry, since this method can add
        additional data into the stream to allow successful insertion.
