 # Password Manager
-A simple password manager with Qt 5 GUI using AES-256-CBC encryption via OpenSSL.
+A simple password manager with Qt 5 GUI and command-line interface using AES-256-CBC encryption via OpenSSL.
+
+## Features
+* Cross-platform: tested under GNU/Linux, Android and Windows
+* Qt Widgets GUI for desktop platforms
+* Qt Quick GUI (using Qt Quick Controls 2 and Kirigami 2) for mobile platforms
+* Interactive command-line interface
+* Simple architecture: All data is stored in ordinary files with AES-256-CBC applied. No cloud stuff. Use
+  eg. Syncthing for synchronization.
+
+## Covered C++/Qt topics
+I've mainly started this project to learn C++ and Qt programming. So beside the mentioned features this project
+and the underlying libraries serve as an example project covering some interesting C++/Qt topics:
+
+* Basic use of Qt Widgets, Qt Quick and Kirigami 2
+* Creating custom Qt models
+    * Nested model and model with multiple columns
+    * Support Drag & Drop in `QTreeView`
+    * Support re-ordering in Qt Quick `ListView`
+    * Use nested and table model within Qt QML
+    * Integration with Qt Widgets' undo/redo framework
+    * Filtering
+* Android tweaks
+    * Add CMake target to invoke `androiddeployqt`
+    * Customize activity
+    * Customize gradle project to add additional Java dependency
+    * Adjust the window style of the activity
+    * Call Java function from C++ and vice verca
+    * Show native file dialog
+    * Open `content://` URL with `std::iostream`
+* Windows specific issues
+    * Open an `std::iostream` for files which have non-ASCII characters in the path
+* Use of zlib to (de)compress buffer
+* Use of OpenSSL for symmetric (de)cryption
