Client Library for OpenStack Barbican Key Management API

Project description

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).

Installation

The client is pip installable as follows:

pip install python-barbicanclient

barbicanclient - Python Library

The full api is documented in the wiki.

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

>>> from keystoneclient.auth import identity
>>> from keystoneclient 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',
...                                  payload_content_type='text/plain')
>>> # 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
