.. _security_module:
:mod:`repoze.bfg.security`
==========================
.. automodule:: repoze.bfg.security
API Functions
~~~~~~~~~~~~~
.. autofunction:: authenticated_userid(context, request)
.. autofunction:: effective_principals(context, request)
.. autofunction:: has_permission
.. autofunction:: principals_allowed_by_permission
.. autofunction:: forget
.. autofunction:: remember
.. autofunction:: view_execution_permitted
Constants
~~~~~~~~~
.. attribute:: Everyone
The special principal id named 'Everyone'. This principal id is
granted to all requests. Its actual value is the string
'system.Everyone'.
.. attribute:: Authenticated
The special principal id named 'Authenticated'. This principal id
is granted to all requests which contain any other non-Everyone
principal id (according to the :term:`authentication policy`).
Its actual value is the string 'system.Authenticated'.
.. attribute:: ALL_PERMISSIONS
An object that can be used as the ``permission`` member of an ACE
which matches all permissions unconditionally. For example, an
ACE that uses ``ALL_PERMISSIONS`` might be composed like so:
``('Deny', 'system.Everyone', ALL_PERMISSIONS)``.
.. attribute:: DENY_ALL
A convenience shorthand ACE that defines ``('Deny',
'system.Everyone', ALL_PERMISSIONS)``. This is often used as the
last ACE in an ACL in systems that use an "inheriting" security
policy, representing the concept "don't inherit any other ACEs".
Return Values
~~~~~~~~~~~~~
.. attribute:: Allow
The ACE "action" (the first element in an ACE e.g. ``(Allow, Everyone,
'read')`` that means allow access. A sequence of ACEs makes up an
ACL. It is a string, and it's actual value is "Allow".
.. attribute:: Deny
The ACE "action" (the first element in an ACE e.g. ``(Deny,
'george', 'read')`` that means deny access. A sequence of ACEs
makes up an ACL. It is a string, and it's actual value is "Deny".
