This module provides a way for securely storing passwords and other secrets.
It uses D-Bus-based FreeDesktop.org Secret Service standard that is, for example, supported by GNOME Keyring (since version 2.30) and by KSecretsService.
It allows one to create new secret items, delete and search for passwords matching given attributes. It also supports graphical prompts when unlocking is needed.
SecretStorage code is hosted on GitHub.

If you don’t know how D-Bus works, please read Introduction to D-Bus firstly.
Before using SecretStorage, you need to initialize D-Bus. This can be done using this function:
Returns new SessionBus. If main_loop is True and no D-Bus main loop is registered yet, registers a default main loop (PyQt5 main loop if use_qt_loop is True, otherwise GLib main loop).
Note
Qt uses GLib main loops on UNIX-like systems by default, so one will rarely need to set use_qt_loop to True.
Creating a new item in the default collection:
>>> import secretstorage
>>> bus = secretstorage.dbus_init()
>>> collection = secretstorage.Collection(bus)
>>> attributes = {'application': 'myapp', 'another attribute':
... 'another value'}
>>> item = collection.create_item('My first item', attributes,
... b'pa$$word')
Getting item’s label, attributes and secret:
>>> item = collection.create_item('My first item', attributes, b'pa$$word')
>>> item.get_label()
'My first item'
>>> item.get_attributes()
{'another attribute': 'another value', 'application': 'myapp'}
>>> item.get_secret()
b'pa$$word'
Locking and unlocking collections:
>>> collection.lock()
>>> collection.is_locked()
True
>>> collection.unlock()
>>> collection.is_locked()
False
Asynchronously unlocking the collection (the GLib main loop is used here, Qt loop is also supported):
>>> from gi.repository import GLib
>>> loop = GLib.MainLoop()
>>> def callback(dismissed, unlocked):
... print('dismissed:', dismissed)
... print('unlocked:', unlocked)
... loop.quit()
...
>>> collection.unlock(callback); loop.run()
dismissed: False
unlocked: [dbus.ObjectPath('/org/freedesktop/secrets/aliases/default')]
