I have written a Python script that I would like to run in the background on my Raspberry Pi. The script makes use of the Python module Keyring (link), which is used to access a keyring backend to provide password input to the script.I wrote the script in OS X, for  which  Keyring makes use of OS X Keychain. But on a headless Raspberry Pi not using X11, something like GNOME Keychain must be installed to act as the backend.I have read the Pypi instructions (referenced below), but I am unfamiliar with D-Bus and how to make it all work in practice. Would anyone be willing to provide a practical example of how D-bus and the GNOME Keyring may be handled by Raspbian, assuming this:The script should always run in the background as long as the Raspberry is powered on, and it is invoked via crontab.The script should run from a virtualenv environment, which has the Keyring module installed.Handling of the GNOME Keyring/D-Bus session is handled as automatically as possible, and can provide the keyring entries to the script without user input (e.g. loaded automatically when the Raspberry is powered on, or the script is executed).I'm quite novice when it comes to these things, so any help would be highly appreciated.https://pypi.python.org/pypi/keyring#using-keyring-on-headless-linux-systemsUsing Keyring on headless Linux systemsIt 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. (Note: I have done this via apt-get).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.
How do I use GNOME Keyring with Python Keyring in virtual environment?
python;d bus;gnome keyring;virtualenv
