Password Manager Daemon is a server that provides a way for applications to securely store and retrieve data at a centralized location. The data is stored in an XML file and clients connect and send commands to manipulate the data.

This is a library making it easy to patch applications to send commands to PWMD. There is an included command line client 'pwmc' that reads protocol commands from stdin or in an interactive shell-like mode and sends them to the pwmd server.
