For those who really want encrypted, secure class files, that isn't 
secure enough.  What's to stop someone from modifying your code to write 
the result to file? What's to stop someone from modifying the JVM to 
allow dumping of classes? Or creating their own class-loader to 
intercept the JVM loading of the class.

I think you're trying to solve an impossible problem.
