pytickets are light-weight symmetrically signed data containers with optional encryption, serialization and compression of their contents. A sample anti-XSRF-library (tickets.web.forms.FormTokenService) based on pytickets is included. It's stateless (as tickets are stand-alone signed containers) and provides more security options than most anti- XSRF-libraries in use today, for instance only allowing pre-declared parameter names to be submitted. http://pypi.python.org/pypi/pytickets/0.9.0 Documentation: http://pytickets.tripleaes.com/
