:param verify: Whether or not to verify SSL certificates for S3 connection.
    By default SSL certificates are verified.
    You can provide the following values:

    - ``False``: do not validate SSL certificates. SSL will still be used
             (unless use_ssl is False), but SSL certificates will not be
             verified.
    - ``path/to/cert/bundle.pem``: A filename of the CA cert bundle to uses.
             You can specify this argument if you want to use a different
             CA cert bundle than the one used by botocore.
