# OpenStego

OpenStego is a steganography application that provides two functionalities:

1. Data Hiding: It can hide any data within an image file.

2. Watermarking: Watermarking image files with an invisible signature. It can be used to detect unauthorized file copying.

## Usage

### For GUI:

Use menu shortcut for OpenStego if you used installer. For zip downloads, use the bundled batch file or shell script to launch the GUI.

```

openstego.bat                (Windows)

```

```

./openstego.sh               (Linux / MacOS)

```

### For command line interface:

Refer to [online documentation](https://www.openstego.com/cmdline.html).

## Development

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](https://jrsoftware.org/isdl.php) to be installed, and `iscc.exe` to be on `PATH`. If you don't want to generate Windows installer, you can skip the same using following command:

```

./gradlew clean dist -x distWin

```
