OpenStego is a steganography application that provides two functionalities:
- Data Hiding: It can hide any data within a cover file (e.g. images).
- Watermarking: Watermarking files (e.g. images) with an invisible signature. It can be used to detect unauthorized file copying.
- For GUI:
java -jar lib\openstego.jar
Use the bundled batch file or shell script to launch the GUI.

Please use the following command to get plugin specific help:

Read the API documentation for the details of the methods to be implemented. In addition, the following utility class can be used to handle multilingual string labels for the plugin:
A new namespace should be added to
LabelUtilclass for each new plugin. Same namespace can also be used for exception messages while throwing
After implementing the plugin classes, create new file named
OpenStegoPlugins.externaland put the fully qualified name of the class which implements
OpenStegoPluginin the file. Make sure that this file is put directly under the CLASSPATH while invoking the application.
Please refer to the
net.sourceforge.openstego.plugin.lsbpackage sources for sample plugin implementation.
