        Installing and Using Python Keyring Lib
        =======================================
        
        .. contents:: **Table of Contents**
        
        ---------------------------
        What is Python keyring lib?
        ---------------------------
        
        The Python keyring lib provides an easy way to access the system keyring service
        from python. It can be used in any application that needs safe password storage.
        
        The keyring library is licensed under both the `MIT license
        <http://opensource.org/licenses/MIT>`_ and the PSF license.
        
        These recommended keyring backends are supported by the Python keyring lib:
        
        * macOS `Keychain
          <https://en.wikipedia.org/wiki/Keychain_%28software%29>`_
        * Freedesktop `Secret Service
          <http://standards.freedesktop.org/secret-service/>`_ supports many DE including
          GNOME (requires `secretstorage <https://pypi.python.org/pypi/secretstorage>`_)
        * KDE4 & KDE5 `KWallet <https://en.wikipedia.org/wiki/KWallet>`_
          (requires `dbus <https://pypi.python.org/pypi/dbus-python>`_)
        * `Windows Credential Locker
          <https://docs.microsoft.com/en-us/windows/uwp/security/credential-locker>`_
        
        Other keyring implementations are available through `Third-Party Backends`_.
        
        -------------------------
        Installation Instructions
        -------------------------
        
        Install from Index
        ==================
        
        Install using your favorite installer. For example:
        
            $ pip install keyring
        
        Linux
        -----
        
        On Linux, the KWallet backend relies on dbus-python_, which does not always
        install correctly when using pip (compilation is needed). So we recommend
        that dbus-python is installed as a system package. The same also applies to
        the Secret Storage backend under Python 2 (under Python 3 a different D-Bus
        implementation is used).
        
        .. _dbus-python: https://gitlab.freedesktop.org/dbus/dbus-python
        
        -------------
        Using Keyring
        -------------
        
        The basic usage of keyring is pretty simple: just call `keyring.set_password`
        and `keyring.get_password`:
        
            >>> import keyring
            >>> keyring.set_password("system", "username", "password")
            >>> keyring.get_password("system", "username")
            'password'
        
        Command-line Utility
        ====================
        
        Keyring supplies a ``keyring`` command which is installed with the
        package. After installing keyring in most environments, the
        command should be available for setting, getting, and deleting
        passwords. For more information on usage, invoke with no arguments
        or with ``--help`` as so::
        
            $ keyring --help
            $ keyring set system username
            Password for 'username' in 'system':
            $ keyring get system username
            password
        
        The command-line functionality is also exposed as an executable
        package, suitable for invoking from Python like so::
        
            $ python -m keyring --help
            $ python -m keyring set system username
            Password for 'username' in 'system':
            $ python -m keyring get system username
            password
        
        --------------------------
        Configure your keyring lib
        --------------------------
        
        The python keyring lib contains implementations for several backends. The
        library will
        automatically choose the keyring that is most suitable for your current
        environment. You can also specify the keyring you like to be used in the
        config file or by calling the ``set_keyring()`` function.
        
        Customize your keyring by config file
        =====================================
        
        This section describes how to change your option in the config file.
        
        Config file path
        ----------------
        
        The configuration of the lib is stored in a file named "keyringrc.cfg". This
        file must be found in a platform-specific location. To determine
        where the config file is stored, run the following::
        
            python -c "import keyring.util.platform_; print(keyring.util.platform_.config_root())"
        
        Some keyrings also store the keyring data in the file system. To determine
        where the data files are stored, run this command::
        
            python -c "import keyring.util.platform_; print(keyring.util.platform_.data_root())"
        
        
        Config file content
        -------------------
        
        To specify a keyring backend, set the **default-keyring** option to the
        full path of the class for that backend, such as
        ``keyring.backends.OS_X.Keyring``.
        
        If **keyring-path** is indicated, keyring will add that path to the Python
        module search path before loading the backend.
        
        For example, this config might be used to load the
        ``SimpleKeyring`` from the ``simplekeyring`` module in
        the ``./demo`` directory (not implemented)::
        
            [backend]
            default-keyring=simplekeyring.SimpleKeyring
            keyring-path=demo
        
        Third-Party Backends
        ====================
        
        In addition to the backends provided by the core keyring package for
        the most common and secure use cases, there
        are additional keyring backend implementations available for other
        use-cases. Simply install them to make them available:
        
        - `keyrings.cryptfile <https://pypi.org/project/keyrings.cryptfile>`_
          - Encrypted text file storage.
        - `keyring_jeepney <https://pypi.org/project/keyring_jeepney>`__ - a
          pure Python backend using the secret service DBus API for desktop
          Linux.
        - `keyrings.alt <https://pypi.org/project/keyrings.alt>`_ - "alternate",
          possibly-insecure backends, originally part of the core package, but
          available for opt-in.
        - `gsheet-keyring <https://pypi.org/project/gsheet-keyring>`_
          - a backend that stores secrets in a Google Sheet. For use with
          `ipython-secrets <https://pypi.org/project/ipython-secrets>`_.
        - `bitwarden-keyring <https://pypi.org/project/bitwarden-keyring/0.1.0/>`_
          - a backend that stores secrets in the `BitWarden <https://bitwarden.com/>`_
          password manager.
        
        
        Write your own keyring backend
        ==============================
        
        The interface for the backend is defined by ``keyring.backend.KeyringBackend``.
        Every backend should derive from that base class and define a ``priority``
        attribute and three functions: ``get_password()``, ``set_password()``, and
        ``delete_password()``. The ``get_credential()`` function may be defined if
        desired.
        
        See the ``backend`` module for more detail on the interface of this class.
        
        Keyring employs entry points to allow any third-party package to implement
        backends without any modification to the keyring itself. Those interested in
        creating new backends are encouraged to create new, third-party packages
        in the ``keyrings`` namespace, in a manner modeled by the `keyrings.alt
        package <https://github.com/jaraco/keyrings.alt>`_. See the ``setup.py`` file
        in that project for a hint on how to create the requisite entry points.
        Backends that prove essential may be considered for inclusion in the core
        library, although the ease of installing these third-party packages should
        mean that extensions may be readily available.
        
        If you've created an extension for Keyring, please submit a pull request to
        have your extension mentioned as an available extension.
        
        Set the keyring in runtime
        ==========================
        
        Keyring additionally allows programmatic configuration of the
        backend calling the api ``set_keyring()``. The indicated backend
        will subsequently be used to store and retrieve passwords.
        
        Here's an example demonstrating how to invoke ``set_keyring``::
        
            # define a new keyring class which extends the KeyringBackend
            import keyring.backend
        
            class TestKeyring(keyring.backend.KeyringBackend):
                """A test keyring which always outputs same password
                """
                priority = 1
        
                def set_password(self, servicename, username, password):
                    pass
        
                def get_password(self, servicename, username):
                    return "password from TestKeyring"
        
                def delete_password(self, servicename, username, password):
                    pass
        
            # set the keyring for keyring lib
            keyring.set_keyring(TestKeyring())
        
            # invoke the keyring lib
            try:
                keyring.set_password("demo-service", "tarek", "passexample")
                print("password stored successfully")
            except keyring.errors.PasswordSetError:
                print("failed to store password")
            print("password", keyring.get_password("demo-service", "tarek"))
        
        
        Using Keyring on Ubuntu 16.04
        =============================
        
        The following is a complete transcript for installing keyring in a
        virtual environment on Ubuntu 16.04.  No config file was used.::
        
          $ sudo apt install python3-venv libdbus-glib-1-dev
          $ cd /tmp
          $ pyvenv py3
          $ source py3/bin/activate
          $ pip install -U pip
          $ pip install secretstorage dbus-python
          $ pip install keyring
          $ python
          >>> import keyring
          >>> keyring.get_keyring()
          <keyring.backends.SecretService.Keyring object at 0x7f9b9c971ba8>
          >>> keyring.set_password("system", "username", "password")
          >>> keyring.get_password("system", "username")
          'password'
        
        
        Using Keyring on headless Linux systems
        =======================================
        
        It is possible to use the SecretService backend on Linux systems without
        X11 server available (only D-Bus is required). To do that, you need the
        following:
        
        * Install the `GNOME Keyring`_ daemon.
        * Start a D-Bus session, e.g. run ``dbus-run-session -- sh`` and run
          the following commands inside that shell.
        * Run ``gnome-keyring-daemon`` with ``--unlock`` option. The description of
          that option says:
        
              Read a password from stdin, and use it to unlock the login keyring
              or create it if the login keyring does not exist.
        
          When that command is started, enter your password into stdin and
          press Ctrl+D (end of data). After that the daemon will fork into
          background (use ``--foreground`` option to prevent that).
        * Now you can use the SecretService backend of Keyring. Remember to
          run your application in the same D-Bus session as the daemon.

        -----------------------------------------------
        Integrate the keyring lib with your application
        -----------------------------------------------
        
        API interface
        =============
        
        The keyring lib has a few functions:
        
        * ``get_keyring()``: Return the currently-loaded keyring implementation.
        * ``get_password(service, username)``: Returns the password stored in the
          active keyring. If the password does not exist, it will return None.
        * ``get_credential(service, username)``: Return a credential object stored
          in the active keyring. This object contains at least ``username`` and
          ``password`` attributes for the specified service, where the returned
          ``username`` may be different from the argument.
        * ``set_password(service, username, password)``: Store the password in the
          keyring.
        * ``delete_password(service, username)``: Delete the password stored in
          keyring. If the password does not exist, it will raise an exception.
        
        In all cases, the parameters (``service``, ``username``, ``password``)
        should be Unicode text. On Python 2, these parameters are accepted as
        simple ``str`` in the default encoding as they will be implicitly
        decoded to text. Some backends may accept ``bytes`` for these parameters,
        but such usage is discouraged.
        
        
        Exceptions
        ==========
        
        The keyring lib raises following exceptions:
        
        * ``keyring.errors.KeyringError``: Base Error class for all exceptions in keyring lib.
        * ``keyring.errors.InitError``: Raised when the keyring can't be initialized.
        * ``keyring.errors.PasswordSetError``: Raise when password can't be set in the keyring.
        * ``keyring.errors.PasswordDeleteError``: Raised when the password can't be deleted in the keyring.

        Security Contact
        ================
        
        If you wish to report a security vulnerability, the public disclosure
        of which may exacerbate the risk, please
        `Contact Tidelift security <https://tidelift.com/security>`_,
        which will coordinate the fix and disclosure privately.
        
        Making Releases
        ===============
        
        This project makes use of automated releases via Travis-CI. The
        simple workflow is to tag a commit and push it to Github. If it
        passes tests on a late Python version, it will be automatically
        deployed to PyPI.
        
        Other things to consider when making a release:
        
         - first ensure that tests pass (preferably on Windows and Linux)
         - check that the changelog is current for the intended release
        
        Running Tests
        =============
        
        Tests are `continuously run <https://travis-ci.org/#!/jaraco/keyring>`_ using
        Travis-CI.
        
        To run the tests yourself, you'll want keyring installed to some environment
        in which it can be tested. Recommended technique is described below.
        
        Using tox
        ---------
        
        Keyring prefers use of `tox <https://pypi.org/project/tox>`_ to run tests.
        Simply install and invoke ``tox``.
        
        This technique is the one used by the Travis-CI script.
