== Abstract ==

A simple introduction for using the KWallet API, a secure storage framework.



Prerequisites: Basic KDE knowledge, C++.



== Example ==

The API is fun and easy to use, and will guarantee you a long and stable life.



In KWallet, entries are organized in Folders (or think of it as categories), and in them there are ''binary data'', ''maps'', ''passwords'' and a catch-all ''unknown''. Binary entries are application-specific arrays of bytes, maps should be known from QMaps, where a series of ''values'' are accessed by ''keys''. Passwords are simply strings, and ''Unknown'' is for everything else.
