*keyrings.envvars* is a keyring backend plugin for the keyring_ utility that provides credentials via environment variables.


Requirements
------------

* keyring >= 23.4.0
* Python >= 3.9


Installation
------------

You can install *keyrings.envvars* via pip_ from PyPI_:

.. code:: console

   $ pip install keyrings.envvars


Usage
-----

*keyrings.envvars* uses the following format for environment variables:

.. code:: console

   KEYRING_SERVICE_NAME_<n>=<service>
   KEYRING_SERVICE_USERNAME_<n>=<username>
   KEYRING_SERVICE_PASSWORD_<n>=<password>

Example for usage with pip credentials:

.. code:: console

   KEYRING_SERVICE_NAME_0=private-pypi-index.example.com
   KEYRING_SERVICE_USERNAME_0=testusername
   KEYRING_SERVICE_PASSWORD_0=testpassword
   KEYRING_SERVICE_NAME_1=another-private-pypi-index.example.com
   KEYRING_SERVICE_USERNAME_1=testusername
   KEYRING_SERVICE_PASSWORD_1=testpassword

This can be used along with a requirements.txt containing appropriate ``--extra-index-url`` flags to avoid storing
credentials in plain-text:

.. code::

   --extra-index-url https://private-pypi-index.example.com/simple

   private-package==1.2.3


Note: Defining multiple identical credentials (service name and username)
will result in the last defined password being returned as the environment
variables are sorted by the keyring backend.

.. code:: console

   export KEYRING_SERVICE_NAME_0=https://private-pypi-index.example.com
   export KEYRING_SERVICE_USERNAME_0=testusername
   export KEYRING_SERVICE_PASSWORD_0=testpassword
   export KEYRING_SERVICE_NAME_1=https://private-pypi-index.example.com
   export KEYRING_SERVICE_USERNAME_1=testusername
   export KEYRING_SERVICE_PASSWORD_1=testpassword_1
   keyring get https://private-pypi-index.example.com testusername
   testpassword_1

If there are multiple credentials defined for a service and no username is given when searching then ``None`` will be returned.
For example, given the definitions above:

.. code:: pycon

   >>> import keyring
   >>> cred = keyring.get_credential('https://private-pypi-index.example.com', None)
   >>> print(cred)
   None
