Plugins help
Please use the following command to get plugin specific help:
java -jar lib\openstego.jar -help -a <algorithm_name> Developing new plugin
To add a new plugin, the following abstract class must be implemented:
net.sourceforge.openstego.OpenStegoPlugin 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:
net.sourceforge.openstego.util.LabelUtil A new namespace should be added to
LabelUtil class for each new plugin. Same namespace can also be used for exception messages while throwing OpenStegoException . After implementing the plugin classes, create new file named
OpenStegoPlugins.external and put the fully qualified name of the class which implements OpenStegoPlugin in 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.lsb package sources for sample plugin implementation. Author
