Data Hiding: It can hide any data within an image file.
Watermarking: Watermarking image files with an invisible signature. It can be used to detect unauthorized file copying.
Use menu shortcut for OpenStego if you used installer. For zip downloads, use the bundled batch file or shell script to launch the GUI.

Fork the repository, clone it locally and execute following to build it fully:
gradlew clean dist (Windows)
./gradlew clean dist (Linux / MacOS)
Note: Windows installer will be generated only if you execute build on Windows environment. It needs Inno Setup to be installed, and
