Description:

djangobasicauthipwhitelist 0.6.0

This simple package ships middleware that lets you to set basic authentication
and IP whitelisting via Django settings.

Use case
This package has been created for staging and demo sites that need to be
completely hidden from the Internet behind a password or accessible only to
certain IP networks.
Do not depend on this package to protect highly valuable information. This
package is at a good way to disable staging sites being discovered by
search engines and Internet users trying to access staging sites. It is
advised that any sensitive information is protected using Django authentication
system.

Requirements

Django 1.8, 1.9, 1.10, 1.11, 2.0, 2.1, 2.2 or 3.0.
Python 3.4, 3.5, 3.6, 3.7 or 3.8.

Installation
The package is on
PyPI so you can
just install it with pip.
pip install django-basic-auth-ip-whitelist

Configuration
In your Django settings you can configure the following settings:

BASIC_AUTH_LOGIN and BASIC_AUTH_PASSWORD
Credentials that you want to use with your basic authentication.

BASIC_AUTH_WHITELISTED_IP_NETWORKS
Set a list of network ranges (strings) compatible with Python’s
ipaddress.ip_network
that you want to be able to access the website without authentication
from. It must be either a string with networks separated by comma or
Python iterable.
Warning: See [Getting IP Address](#getting-ip-address) below for caveats around IP address detection.

BASIC_AUTH_REALM
String specifying the realm of the default response.

Example settings
MIDDLEWARE += [
'baipw.middleware.BasicAuthIPWhitelistMiddleware'
]
BASIC_AUTH_LOGIN = 'somelogin'
BASIC_AUTH_PASSWORD = 'greatpassword'
BASIC_AUTH_WHITELISTED_IP_NETWORKS = [
'192.168.0.0/28',
'2001:db00::0/24',
]

Advanced customisation

Getting IP Address
By default, BasicAuthIPWhitelistMiddleware uses request.META["REMOTE_ADDR"]
as the client’s IP, which corresponds to the IP address connecting to Django.
If you have a reverse proxy (eg nginx in front), this will result in the IP address of
nginx, not the client.
Correctly determining the IP address can vary between deployments. Guessing incorrectly can
result in security issues. Instead, this library requires you configure this yourselves.
In most deployments, the X-Forwarded-For header can be used to correctly determine the
client’s IP. We recommend django-xff to help parse this
header correctly. Because django-xff overrides REMOTE_ADDR by default, it is natively
supported by BasicAuthIPWhitelistMiddleware.
django-ipware is another popular
library, however may take more customization to implement.
To fully customize IP address detection, you can set BASIC_AUTH_GET_CLIENT_IP_FUNCTION to
a function which takes a request and returns a valid IP address:
BASIC_AUTH_GET_CLIENT_IP_FUNCTION = 'utils.ip.get_client_ip'

BASIC_AUTH_WHITELISTED_HTTP_HOSTS
Set a list of hosts that your website will be open to without basic
authentication. This is useful if your website is hosted under multiple domains
and you want only one of them to be publicly visible, e.g. by search engines.
This is by no means a security feature. Please do not use to secure your
site.
BASIC_AUTH_WHITELISTED_HTTP_HOSTS = [
'your-public-domain.com',
]

BASIC_AUTH_WHITELISTED_PATHS
Set a list of paths that your website will serve without basic authentication.
This can be used to support API integrations for example with third-party
services which don’t support basic authentication.
Paths listed in the setting BASIC_AUTH_WHITELISTED_PATHS are treated as roots, and any subpath will be whitelisted too. For example:
BASIC_AUTH_WHITELISTED_PATHS = [
'/api',
]
This will open up the path https://mydomain.com/api/, as well as anything
below it, e.g. https://mydomain.com/api/document/1/.

BASIC_AUTH_RESPONSE_TEMPLATE
If you want to display a different template on the 401 page, please use this
setting to point at the template.
BASIC_AUTH_RESPONSE_TEMPLATE = '401.html'

BASIC_AUTH_RESPONSE_CLASS
If you want to specify custom response class, you can do so with this setting.
Provide the path as a string.
BASIC_AUTH_RESPONSE_CLASS = 'yourmodule.response.CustomUnathorisedResponse'

BASIC_AUTH_DISABLE_CONSUMING_AUTHORIZATION_HEADER
Set this setting to True if you want the Authorization HTTP header to not be deleted from the request object after it has been used by this package’s middleware.
BASIC_AUTH_DISABLE_CONSUMING_AUTHORIZATION_HEADER = True

Skip middleware
You can skip the middleware by setting
_skip_basic_auth_ip_whitelist_middleware_check attribute on the request to
True.
setattr(request, '_skip_basic_auth_ip_whitelist_middleware_check', True)
This may be handy if you have other middleware that you want to have
co-existing different middleware that restrict access to the website.
