python-oauth-token-manager 0.3.3

API for managing stored OAuth credentials.

Python Library for storing OAuth credentials in many locations

What's this for?

By their very nature, OAuth credentials are valuable and dangerous, and have to be stored securely. As a result, the same tasks to store these tokens in a simple and secure fashion have to be written each time, or copied and pasted around - leading to potential issues as problems are found and not fixed in all places.

This library will store OAuth tokens in any of the following places:

1. Secret Manager
2. Firestore
3. Google Cloud Storage files
4. A local json file

Other storage locations can be added at will simply by forking this library and extending the appropriate abstract classes.

Initial Setup And Installation

Examples

Fetching a token from storage

from auth.credentials_helpers import encode_key
from auth.secret_manager import SecretManager

manager = SecretManager(project='<gcp project name>')
key = manager.get_document(encode_key('<token id>'))

Note the use of encode_key. This is because many of the storage systems supported do not allow special characters, and the most convenient identifier for most OAuth tokens is the email address of the user. encode_key is a base64 encoder - and no decoding is necessary.

The example given uses Secret Manager (part of Google Cloud). To use (say) GCS, the code would change like this:

from auth.credentials_helpers import encode_key
from auth.gcs_datastore import GCSDatastore

manager = GCSDatastore(project='<gcp project name>', bucket='<gcs bucket>')
key = manager.get_document(encode_key('<token id>'))

All that changes is where the datastore is!

Storing a token in Secret Manager

from auth.secret_manager import SecretManager
manager = SecretManager(project='<gcp project name>')

manager.update_document(id=encode_key('<token_id>'), new_data=<token string>)

This will implicitly create a secret if there was not one already, or simply update an existing secret with a new 'live' version of the secret.

Listing all the available secrets

from auth.secret_manager import SecretManager
manager = SecretManager(project='<gcp project name>')

manager.list_documents()

Removing a secret

from auth.secret_manager import SecretManager
manager = SecretManager(project='<gcp project name>')

manager.delete_document(id=encode_key('<token_id>'))
