This is a client for the Barbican Key Management API. There is a Python library for accessing the API (barbicanclient module), and a command-line script (barbican).
The client is pip installable as follows:
pip install python-barbicanclientThe full api is documented in the official OpenStack documentation site.
Here's an example of storing a secret in barbican using the python library with keystone authentication:
>>> 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='http://localhost:5000/v3',
... username='admin_user',
... user_domain_name='Default',
... password='password',
... project_name='demo',
... project_domain_name='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='Self destruction sequence',
... payload='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()
'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('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 ossifrageNote
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]
