What is D-Bus? D-Bus is a system for interprocess communication (IPC). Architecturally, it has several layers: A library, libdbus, that allows two applications to connect to each other and exchange messages. A message bus daemon executable, built on libdbus, that multiple applications can connect to. The daemon can route messages from one application to zero or more other applications. Wrapper libraries or bindings based on particular application frameworks. For example, libdbus-glib and libdbus-qt. There are also bindings to languages such as Python. These wrapper libraries are the API most people should use, as they simplify the details of D-Bus programming. libdbus is intended to be a low-level backend for the higher level bindings. Much of the libdbus API is only useful for binding implementation. libdbus only supports one-to-one connections, just like a raw network socket. However, rather than sending byte streams over the connection, you send messages. Messages have a header identifying the kind of message, and a body containing a data payload. libdbus also abstracts the exact transport used (sockets vs. whatever else), and handles details such as authentication.

簡介keyring函式庫 The Python keyring library provides an easy way to access the system keyring service from python. It can be used in any application that needs safe password storage.
