        This is a required field.

        Ideally you will want to compute this value with checksums from
        previous uploaded parts, using the algorithm described in
        `Glacier documentation <http://docs.aws.amazon.com/amazonglacier/latest/dev/checksum-calculations.html>`_.

        But if you prefer, you can also use botocore.utils.calculate_tree_hash()
        to compute it from raw file by::

            checksum = calculate_tree_hash(open('your_file.txt', 'rb'))
