django_tlsauth 0.1.1 (beta)

Django app implementing TLS Authentication - simple client certificate CA inclusive

• Django-TLSAuth

Django-TLSAuth integrates a minimal certificate authority (CA) and implements TLS client certificate authentication. It depends on nginx for handling the TLS authentication part.

** Installation #+BEGIN_SRC sh

pip install django_tlsauth

#+END_SRC

Django-TLSAuth depends on tlsauth which provides minimal tools to act as a CA. Please follow the "CA and https service install" steps from https://github.com/stef/tlsauth to set up your webserver and CA.

After setting up the CA, you should also configure it in django, put something like this with adjusted paths into your settings.py:

#+BEGIN_SRC python from tlsauth import CertAuthority

TLS_CA=CertAuthority('tlsauth/CA/public/root.pem',

'tlsauth/CA/private/root.pem', 'tlsauth/CA/conf/serial', 'tlsauth/CA/dummy.pem', 'http://www.example.com/crl.pem', 'tlsauth/CA/incoming', )

TLS_ADMINGROUPS=['CA admins'] TLS_SCRUTINIZER=None # supply your own function authorizing automatic signatures TLS_BLINDSIGN=False # blindly sign incoming CSRs #+END_SRC

If you want to enable the admin to the mini-CA add to your urls.py

#+BEGIN_SRC python url(r'^tlsauth/', include('django_tlsauth.urls')), #+END_SRC

** tlsauth decorator Django-TLSAuth provides a simple decorator to guard your entry points: #+BEGIN_SRC python from django.http import HttpResponse, HttpResponseRedirect from django_tlsauth.views import tlsauth

def unauth(request):

return HttpResponseRedirect('/')

@tlsauth(unauth=unauth, groups=['helloworldophobians']) def hello(request):

return HttpResponse("hello world")

#+END_SRC

** Managing certs Django-TLSAuth provides a few default routes to manage the certs and the CA.

*** /tlsauth/register/ Visitors can register like on a normal site, but when done, they get a PKCS12 certificate ready to be saved and imported in all browsers. This is totally automatic and there's no check if the specified organization is not a privileged one (like "CA admins" in the above example). This really provides no security, for bots and scripts it's even easier to use these certs than for normal humans. Other mechanisms must be deployed to provide meaningful authentication.

*** /tlsauth/certify/ Visitors can submit their Certificate Signing Request (can be easily generated using gencert.sh from tlsauth), which depending on configuration either returns automatically a signed certificate (no meaningful authentication this way, avoid this!), or it gets stored for later approval by the "CA admins".

*** /tlsauth/cert/ Returns the CA root certificate in PEM format, for import into your browser.

*** /tlsauth/csrs/ Displays a list of incoming CSRs to any certified member of the "CA admin" group. The certs can be either rejected or signed, in the later case the resulting certificate is sent to the email address of the subject.

*** /tlsauth/test/ Displays whether you are TLS authenticated and what your distinguished name is.
