Token provider
|
|
==============
|
|
|
|
OpenStack Identity supports customizable token providers. This is specified
|
|
in the ``[token]`` section of the configuration file. The token provider
|
|
controls the token construction, validation, and revocation operations.
|
|
|
|
You can register your own token provider by configuring the following property:
|
|
|
|
.. note::
|
|
|
|
More commonly, you can use this option to change the token provider to one
|
|
of the ones built in. Alternatively, you can use it to configure your own
|
|
token provider.
|
|
|
|
* ``provider`` - token provider driver.
|
|
Defaults to ``fernet``.
|
|
Implemented by :class:`keystone.token.providers.fernet.Provider`. This is the
|
|
entry point for the token provider in the ``keystone.token.provider``
|
|
namespace.
|
|
|
|
Each token format uses different technologies to achieve various performance,
|
|
scaling, and architectural requirements. The Identity service includes
|
|
``fernet``, ``pkiz``, ``pki``, and ``uuid`` token providers.
|
|
|
|
Below is the detailed list of the token formats:
|
|
|
|
UUID
|
|
``uuid`` tokens must be persisted (using the back end specified in the
|
|
``[token] driver`` option), but do not require any extra configuration
|
|
or setup.
|
|
|
|
PKI and PKIZ
|
|
``pki`` and ``pkiz`` tokens can be validated offline, without making HTTP
|
|
calls to keystone. However, this format requires that certificates be
|
|
installed and distributed to facilitate signing tokens and later validating
|
|
those signatures.
|
|
|
|
Fernet
|
|
``fernet`` tokens do not need to be persisted at all, but require that you run
|
|
``keystone-manage fernet_setup`` (also see the
|
|
``keystone-manage fernet_rotate`` command).
|
|
|
|
.. warning::
|
|
|
|
UUID, PKI, PKIZ, and Fernet tokens are all bearer tokens. They
|
|
must be protected from unnecessary disclosure to prevent unauthorized
|
|
access.
