information about this, have a look at :ref:`json-security`.

If the argument ``padded`` true than the json object will pad for
JSONP calls like from jquery. The response mimetype will also change
to ``text/javascript``.
The json object will pad as javascript function with the function name
from the request argument ``callback`` or ``jsonp``. If the argument
``padded`` a string jsonify will look for the function name in the
request argument with the name which is equal to ``padded``. Is there
no function name it will fallback and use ``jsonp`` as function name.
