Light weight module that allows you to store secrets encrypted in JSON and access them easily in your Django project.
Project description
DJSM - Django JSON Secrets Manager
Light weight Python module that allows you to easily store and access your Django project's secrets like secret key, database password, etc., encrypted in a JSON file.
Installation and Quick Setup
- Install the package using pip
pip install djsm
- Initial setup:
Copy this into a .env file just outside your project (adjust as needed)
DJSM_SECRETS_FILE_PATH = "./.secretfolder/path/secrets.json"
# Assign path to file you want secrets to be stored in. Even if it does not exist yet
# NOT MANDATORY
DJSM_SECRET_KEY_NAME = "secretkey"
Your project structure should look like this:
|-- my_project
| |-- my_project
| | |-- __init__.py
| | |-- settings.py
| | |-- urls.py
| | |-- wsgi.py
| |
| |-- my_app
| | |-- __init__.py
| | |-- admin.py
| | |-- apps.py
| | |-- models.py
| | |-- tests.py
| | |-- views.py
| |
| |-- db.sqlite3
| |-- manage.py
|
|-- venv
|-- .env
|-- .gitignore
|-- requirements.txt
- Import the package in your Django project
In settings.py
from djsm import get_djsm
manager = get_djsm()
- Run server
python manage.py runserver
If everything was setup successfully, you should see "Setup OK!" on the terminal.
Usage
Before starting, a '.env' file as to be created just outside the django project directory. In the file, the following should be added;
DJSM_SECRETS_FILE_PATH
-> Path(preferably absolute) to file where all secrets will be stored. Example:
SECRETS_FILE_PATH = "/.secrets/pathtofile/secrets.json"
DJSM_SECRET_KEY_NAME
-> Name with which the Django secret key should be stored. Example:
DJSM_SECRET_KEY_NAME = 'django_secret_key'
Creating and using a secrets manager
get_djsm
returns a DJSM object instantiated using values defined in .env file after performing necessary checks.
from djsm import get_djsm
manager = get_djsm(quiet=False)
You can set quiet=True
if you do not want to see messages on the terminal. Although, important messages are always displayed.
To generate a new secret key or use and existing one. In settings.py:
# generate secret key if it does not exist
SECRET_KEY = manager.get_or_create_secret_key()
To update or add a new secret:
new_secret = {"DB_PASSWORD": "db_password"}
manager.update_secrets(new_secret)
Once the update has been performed you can delete these lines.
To get a secret:
# Get a secret, say DB_PASSWORD
db_password = manager.get_secret("DB_PASSWORD")
DjangoJSONSecretManager
This class is the main class of the module. It provides the following methods:
-
get_secret(secret_name)
-> Returns the secret with the namesecret_name
if it exists, otherwise returnsNone
-
update_secrets(new_secrets)
-> Updates the secrets file with the new secrets provided in thenew_secrets
dictionary. If a secret already exists, it is updated, otherwise, it is added. -
get_or_create_secret_key()
-> Returns the Django secret key if it exists, otherwise generates a new one and returns it -
write_secrets(secrets, path_to_secret_file, **kwargs)
-> Writes secrets to the secrets file whose path is provided. -
load_secrets(path_to_secret_file, **kwargs)
-> Loads secrets from the secrets file whose path is provided. -
change_crypt_keys()
-> Changes the encryption keys used to encrypt and decrypt secrets. This is useful if you want to change the encryption keys used to encrypt and decrypt existing secrets. -
clean_up()
-> Deletes the secret key file and the secrets file and clears all environment variables set by the module. -
reload_env()
-> Reloads the environment variables from the .env file. -
clean_up_and_reload()
-> Calls theclean_up()
andreload_env()
methods.
How to use the DJSM
class:
from djsm import DJSM # DJSM is an alias for DjangoJSONSecretManager
# Instantiation
manager = DJSM('./.secretfolder/secrets.json')
# get a secret, say DB_PASSWORD
db_password = manager.get_secret("DB_PASSWORD")
# generate a new secret key
new_secret_key = manager.get_or_create_secret_key()
# update secrets or add new secrets
new_secret = {"DB_PASSWORD": "new_db_password"}
manager.update_secrets(new_secret)
# change encryption and decryption keys
manager.change_crypt_keys()
DO NOT DELETE cryptkeys.json
. IF YOU DO, ALL ENCRYPTED SECRET WILL BE LOST
NOTE: DJSM just provides an added layer of security in managing secrets in your application. It is not tested to be completely attack proof.
