# Password Manager A simple [password manager](https://en.wikipedia.org/wiki/Password_manager) with Qt 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) 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 * 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 * Create APK via CMake (using `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 Note that some of the mentioned points are actually implemented the underlying libraries [c++utilities](http://github.com/Martchus/cpp-utilities), [qtutilities](http://github.com/Martchus/qtutilities) and [passwordfile](http://github.com/Martchus/passwordfile). ## Download ### Source See the release section on GitHub. ### Packages and binaries * Arch Linux * for PKGBUILDs checkout [my GitHub repository](https://github.com/Martchus/PKGBUILDs) or [the AUR](https://aur.archlinux.org/packages?SeB=m&K=Martchus) * there is also a [binary repository](https://martchus.no-ip.biz/repo/arch/ownstuff) * Tumbleweed, Leap, Fedora * RPM \*.spec files and binaries are available via openSUSE Build Service * remarks * Be sure to add the repository that matches the version of your OS and to keep it in sync when upgrading. * The linked download pages might be incomplete, use the repositories URL for a full list. * latest releases: [download page](https://software.opensuse.org/download.html?project=home:mkittler&package=passwordmanager), [repositories URL](https://download.opensuse.org/repositories/home:/mkittler), [project page](https://build.opensuse.org/project/show/home:mkittler) * Git master: [download page](https://software.opensuse.org/download.html?project=home:mkittler:vcs&package=passwordmanager), [repositories URL](https://download.opensuse.org/repositories/home:/mkittler:/vcs), [project page](https://build.opensuse.org/project/show/home:mkittler:vcs) * Other GNU/Linux systems * for generic, self-contained binaries checkout the [release section on GitHub](https://github.com/Martchus/passwordmanager/releases) * Requires glibc>=2.26, OpenGL and libX11 * openSUSE Leap 15, Fedora 27, Debian 10 and Ubuntu 18.04 are recent enough (be sure the package `libopengl0` is installed on Debian/Ubuntu) * Supports X11 and Wayland (set the environment variable `QT_QPA_PLATFORM=xcb` to disable native Wayland support if it does not work on your system) * Binaries are signed with the GPG key [`B9E36A7275FC61B464B67907E06FE8F53CDC6A4C`](https://keyserver.ubuntu.com/pks/lookup?search=B9E36A7275FC61B464B67907E06FE8F53CDC6A4C&fingerprint=on&op=index). * Windows * for binaries checkout the [release section on GitHub](https://github.com/Martchus/tageditor/releases) * the Qt 6 based version is stable and preferable but only supports Windows 10 version 1809 and newer * the Qt 5 based version should still work on older versions down to Windows 7 although this is not regularly checked * Binaries are signed with the GPG key [`B9E36A7275FC61B464B67907E06FE8F53CDC6A4C`](https://keyserver.ubuntu.com/pks/lookup?search=B9E36A7275FC61B464B67907E06FE8F53CDC6A4C&fingerprint=on&op=index). * for mingw-w64 PKGBUILDs checkout [my GitHub repository](https://github.com/Martchus/PKGBUILDs) ## Build instructions The application depends on [c++utilities](https://github.com/Martchus/cpp-utilities) and [passwordfile](https://github.com/Martchus/passwordfile) and is built the same way as these libraries. For basic instructions checkout the README file of [c++utilities](https://github.com/Martchus/cpp-utilities). When the Qt GUI is enabled, Qt and [qtutilities](https://github.com/Martchus/qtutilities) are required, too. To avoid building c++utilities/passwordfile/qtutilities separately, follow the instructions under "Building this straight". There's also documentation about [various build variables](https://github.com/Martchus/cpp-utilities/blob/master/doc/buildvariables.md) which can be passed to CMake to influence the build. ### Optional dependencies * When building any Qt GUI, the library qtutilities is required. * When building with Qt Widgets GUI support, the following Qt modules are required (version 5.6 or higher): core gui widgets * When building with support for the experimental Qt Quick GUI, the following Qt/KDE modules are required (version 6.6 or higher): core gui qml quick quickcontrols2 kirigami To specify the major Qt version to use, set `QT_PACKAGE_PREFIX` (e.g. add `-DQT_PACKAGE_PREFIX:STRING=Qt6` to the CMake arguments). There's also `KF_PACKAGE_PREFIX` for KDE dependencies. Note that the Qt Quick GUI always requires the same major Qt version as your KDE modules use. ### Building this straight 0. Install (preferably the latest version of) the GCC toolchain or Clang, the required Qt modules, OpenSSL, iconv, zlib, CMake and Ninja. 1. Get the sources of additional dependencies and the password manager itself. For the latest version from Git clone the following repositories: ``` cd "$SOURCES" git clone https://github.com/Martchus/cpp-utilities.git c++utilities git clone https://github.com/Martchus/passwordfile.git git clone https://github.com/Martchus/qtutilities.git # only required for Qt GUI git clone https://github.com/Martchus/passwordmanager.git git clone https://github.com/Martchus/subdirs.git ``` 2. Build and install everything in one step: ``` cd "$BUILD_DIR" cmake \ -G Ninja \ -DCMAKE_BUILD_TYPE=Release \ -DCMAKE_INSTALL_PREFIX="/install/prefix" \ "$SOURCES/subdirs/passwordmanager" ninja install ``` * If the install directory is not writable, do **not** conduct the build as root. Instead, set `DESTDIR` to a writable location (e.g. `DESTDIR="temporary/install/dir" ninja install`) and move the files from there to the desired location afterwards. #### Concrete example of 3. for building an Android APK under Arch Linux Create a key for signing the package (always required; otherwise the APK file won't install): ``` # set variables for creating keystore and androiddeployqt to find it export QT_ANDROID_KEYSTORE_PATH=/path/to/keystore-dir QT_ANDROID_KEYSTORE_ALIAS=$USER-devel QT_ANDROID_KEYSTORE_STORE_PASS=$USER-devel QT_ANDROID_KEYSTORE_KEY_PASS=$USER-devel # create keystore (do only once) mkdir -p "${QT_ANDROID_KEYSTORE_PATH%/*}" pushd "${QT_ANDROID_KEYSTORE_PATH%/*}" keytool -genkey -v -keystore "$QT_ANDROID_KEYSTORE_ALIAS" -alias "$QT_ANDROID_KEYSTORE_ALIAS" -keyalg RSA -keysize 2048 -validity 10000 popd ``` Build c++utilities, passwordfile, qtutilities and passwordmanager in one step to create an Android APK for aarch64: ``` # use Java 17 (the latest Java doesn't work at this point) and avoid unwanted Java options export PATH=/usr/lib/jvm/java-17-openjdk/bin:$PATH export _JAVA_OPTIONS= # configure and build using helpers from android-cmake package android_arch=aarch64 build_dir=$BUILD_DIR/../manual/passwordmanager-android-$android_arch-release source /usr/bin/android-env $android_arch android-$android_arch-cmake -G Ninja -S . -B "$build_dir" \ -DCMAKE_FIND_ROOT_PATH="${ANDROID_PREFIX}" -DANDROID_SDK_ROOT="${ANDROID_HOME}" \ -DPKG_CONFIG_EXECUTABLE:FILEPATH=/usr/bin/android-$android_arch-pkg-config \ -DBUILTIN_ICON_THEMES='breeze;breeze-dark' -DBUILTIN_TRANSLATIONS=ON \ -DQT_PACKAGE_PREFIX:STRING=Qt6 -DKF_PACKAGE_PREFIX:STRING=KF6 cmake --build "$build_dir" # install the app adb install "$build_dir/passwordmanager/android-build//build/outputs/apk/release/android-build-release-signed.apk" ``` ##### Notes * The Android packages for the dependencies Boost, Qt, iconv, OpenSSL and Kirigami are provided in my [PKGBUILDs](http://github.com/Martchus/PKGBUILDs) repo. * The latest Java I was able to use was version 17. * Use `QT_QUICK_CONTROLS_STYLE=Material` and `QT_QUICK_CONTROLS_MOBILE=1` to test the Qt Quick GUI like it would be shown under Android via a normal desktop build. ### Building without Qt GUI It is possible to build without the GUI if only the CLI is needed. In this case no Qt dependencies (including qtutilities) are required. To build without GUI, add the following parameters to the CMake call: ``` -DWIDGETS_GUI=OFF -DQUICK_GUI=OFF ``` ## Copyright notice and license Copyright © 2015-2024 Marius Kittler All code is licensed under [GPL-2-or-later](LICENSE).
