If you are using Pypi to install the package you do not have to download the source code manually. Stable releases of the source code can be found on the download page or on Github.

git clone


You can install the package from Pypi with easy_install or pip.

easy_install shadowd
pip install shadowd

Or by hand.

python install


To protect CGI applications you simply have to load the module.

import shadowd.cgi_connector


Django applications require a small modification. It is necessary to create a hook to intercept requests. To do this create the file middleware/ in the application directory.

from shadowd.django_connector import InputDjango, OutputDjango, Connector

def shadowdconnector(get_response):
    def middleware(request):
        input = InputDjango(request)
        output = OutputDjango()

        status = Connector().start(input, output)
        if not status == True:
            return status

        return get_response(request)

    return middleware

There also has to be an empty file in the middleware directory. Next you have to register the middleware in the file of your application.

    # ...

The connector should be at the beginning of the MIDDLEWARE_CLASSES list.


Flask applications require a small modification as well. It is necessary to create a hook to intercept requests.

from flask import Flask, request
from shadowd.flask_connector import InputFlask, OutputFlask, Connector

app = Flask(__name__)

def before_req():
    input = InputFlask(request)
    output = OutputFlask()

    Connector().start(input, output)


Copy the configuration file from misc/examples/connectors.ini to /etc/shadowd/connectors.ini and edit it. The file is annotated and should be self-explanatory, but if you are stuck you can find more information in the documentation. Make sure that it is readable by the web server user, otherwise your site will not work anymore.

If you plan to protect multiple applications you can use the environment variable SHADOWD_CONNECTOR_CONFIG to specify different configuration files for every target.

Ignore sensitive input!

You should use the ignore function of the connector to disregard very sensitive input, e.g., passwords.
