This is a client for the `Barbican <https://github.com/openstack/barbican>`__
Key Management API.  There is a Python library for accessing the API
(`barbicanclient` module), and a command-line script (`barbican`).

Installation
------------

The client is
`pip installable <https://pypi.python.org/pypi/python-barbicanclient>`__ as
follows:

.. code:: console

  pip install python-barbicanclient


barbicanclient - Python Library
-------------------------------

The full api is
`documented in the official OpenStack documentation site <https://docs.openstack.org/python-barbicanclient/latest/>`__.


Here's an example of storing a secret in barbican using the python library
with keystone authentication:

.. code:: python

    >>> from keystoneclient.auth import identity
    >>> from keystoneauth1 import session
    >>> from barbicanclient import client

    >>> # We'll use Keystone API v3 for authentication
    >>> auth = identity.v3.Password(auth_url=u'http://localhost:5000/v3',
    ...                             username=u'admin_user',
    ...                             user_domain_name=u'Default',
    ...                             password=u'password',
    ...                             project_name=u'demo',
    ...                             project_domain_name=u'Default')

    >>> # Next we'll create a Keystone session using the auth plugin we just created
    >>> sess = session.Session(auth=auth)

    >>> # Now we use the session to create a Barbican client
    >>> barbican = client.Client(session=sess)

    >>> # Let's create a Secret to store some sensitive data
    >>> secret = barbican.secrets.create(name=u'Self destruction sequence',
    ...                                  payload=u'the magic words are squeamish ossifrage')

    >>> # Now let's store the secret by using its store() method. This will send the secret data
    >>> # to Barbican, where it will be encrypted and stored securely in the cloud.
    >>> secret.store()
    u'http://localhost:9311/v1/secrets/85b220fd-f414-483f-94e4-2f422480f655'

    >>> # The URI returned by store() uniquely identifies your secret in the Barbican service.
    >>> # After a secret is stored, the URI is also available by accessing
    >>> # the secret_ref attribute.
    >>> print(secret.secret_ref)
    http://localhost:9311/v1/secrets/091adb32-4050-4980-8558-90833c531413

    >>> # When we need to retrieve our secret at a later time, we can use the secret_ref
    >>> retrieved_secret = barbican.secrets.get(u'http://localhost:9311/v1/secrets/091adb32-4050-4980-8558-90833c531413')
    >>> # We can access the secret payload by using the payload attribute.
    >>> # Barbican decrypts the secret and sends it back.
    >>> print(retrieved_secret.payload)
    the magic words are squeamish ossifrage

.. note::

    In order for the example above to work Barbican must be running and
    configured to use the Keystone Middleware. For more information on
    setting this up please visit:
    https://docs.openstack.org/barbican/latest/configuration/keystone.html [1]_
