# This currently is not a keyring, it's more like a joke.
# No, seriously.
# We're affected by this **bug**

# https://bitbucket.org/kang/python-keyring-lib/
# issue/65/dbusexception-method-opensession-with

# so using the gnome keyring does not seem feasible right now.
# I thought this was the next best option to store secrets in plain sight.

# in the future we should move to use the gnome/kde/macosx/win keyrings.
