auth_pubtkt 0.1

This software implements mod_auth_pubtkt authentication for Python world.

Ticket creation

Importing nessesary modules:

>>> from M2Crypto import RSA
>>> import auth_pubtkt
>>> import auth_pubtkt.tests
>>> import os.path
>>> import time, datetime

Loading RSA private key from tests package:

>>> privkey_path = os.path.join(os.path.dirname(auth_pubtkt.tests.__file__), 'rsa_priv.pem')
>>> privkey = RSA.load_key(privkey_path)

Set expiration time to 2011/01/01 00:00

>>> validuntil = int(time.mktime(datetime.datetime(2011, 1, 1).timetuple()))

Generating ticket for user ‘john’:

>>> ticket = auth_pubtkt.create_ticket(privkey, 'john', validuntil, tokens=['su'])
>>> ticket
'uid=john;validuntil=1293814800;tokens=su;sig=YuM/RL8ub+XMb0ZTTlFYF6ehwRV8SnKx+TLj/syZmVx1ncR4QD58OMdRkmdmDCY9sdsoivcf+ACRCRX19nmEc5Ba+182FyRKC8bGL51GwPs+lMgaIaXxvhSvRbl/00sTWny+XEv1fEQDSc5tw3/ug6/YA9xt2wywUX1+hxfWQ5U='

Middleware

>>> import urllib
>>> pubkey_path = os.path.join(os.path.dirname(auth_pubtkt.tests.__file__), 'rsa_pub.pem')
>>> pubkey = RSA.load_pub_key(pubkey_path)
>>> def test_app(environ, start_response):
...    for key in sorted(environ.keys()):
...        print '%s: %s' % (key, environ[key])
>>> app = auth_pubtkt.AuthPubTKTMiddleware(test_app, pubkey)
>>> env = {}
>>> env['REMOTE_ADDR'] = '192.168.1.10'
>>> env['REQUEST_METHOD'] = 'GET'
>>> env['HTTP_COOKIE'] = 'auth_pubtkt="%s"' % urllib.quote(ticket)
>>> app(env, lambda status, start: None)
