Secret distribution tool, written as a wrapper on credstash

Project Description


.. image::

Razorpay's Secret Credential management system.


alohomora is distributed via PyPi:

.. code:: shell
pip install razorpay.alohomora


Alohomora is an opinionated project that relies on our conventions to
intelligently fetch secrets at run-time.

We don't do our own crypto. We rely on these libraries instead:


This is how the template file looks in our app

.. code:: j2

# {{ alohomora_managed }}
DB_PASSWORD = {{ lookup('db_password') }}
APP_ENV = {{ env }}
APP_NAME = {{ app }}

This repo runs directly on the same template and generates the
equivalent file as the output.

The steps it follows are the following:

1. Figure out the tables from which to read. All secrets are stored in a
``credstash-env-app`` table structure in dynamoDB.
2. Fetch all secrets from that table using credstash
3. Render the template with the secrets using jinja

How it Works?

Alohomora expects the secrets for any application to be stored in a
table called ``credstash-{env}-{app}``. The IAM roles for this table
must be configured by you. Once you try to render a template, alohomora
will do the following:

1. Read the entire table and decrypt all secrets and cache them locally.
2. Render the template with these files and 3 extra variables: ``env``,
``app``, and ``ENV`` variables.

``ENV`` is same as `os.environ` inside the jinja template.


Alohomora is designed to be a zero-config solution.

We perform a few transforms on the arguments that are passed:

- Change both ``app`` and ``env`` to lowercase
- Replace ``production`` with ``prod`` in the ``env`` name
- Ignore anything after ``-`` in the environment. So ``beta-birdie`` becomes ``beta``


Please see the wiki regarding alohomora binary usage.


``alohomora`` is released under the same license as credstash.
