Creating non-reverse-engineerable Java programs

Question

Is there a way to deploy a Java program in a format that is not reverse-engineerable?

I know how to convert my application into an executable JAR file, but I want t

Answer 1

Even if you compile the code into native machine language, there are all sorts of programs that let you essentially decompile it into assembly language and follow the process flow (OlyDbg, IDA Pro).

Answer 2

Don't use an interpreted language? What are you trying to protect anyway? If it's valuable enough, anything can be reverse engineered. The chances of someone caring enough to reverse engineer most projects is minimal. Obfuscation provides at least a minimal hurdle.

Ensure that your intellectual property (IP) is protected via other mechanisms. Particularly for security code, it's important that people be able to inspect implementations, so that the security is in the algorithm, not in the source.
