How can I check if my class encryption tool works reliably?

You may use our debugging agent to test your code encryption tool. Download JSecurityAgent.jar and run your application with the additional parameter -javaagent:JSecurityAgent.jar. The bytecode agent displays all classes of which it can get the bytecode. If you see a line like

BytecodeAgent: Got bytecode of  my/encrypted/class

your tool is vulnerable.
