Hi, I'm trying to use Radon in version 1.0.1 and I'm interested in these things. I will use it mainly for classic jar files (standalone) in Java SE 10 and later on 11

1) Is it possible to only obfuscate a specific package? E.g. only my package "my.app.nextname"

2) Would you be able to add a checkbox to skip a comment in the JAR archive? When I send someone an obfuscate application and he sees what he was obfuscated, it would only reduce security

3) Can you add descriptions for different methods/inputs in the GUI? E.g. what is it doing and preview the code before and after?

Thx

  1. Regex allows for pattern exclusion so I believe so.

  2. I'm not sure. There's multiple watermarks embedded by Radon so the comment is not the only watermark.

  3. This will not be implemented. Sorry :(

Thanks for the reply. I have one more question.

I tried to obfuscate some JAR and open it in JD GUI 1.4 (java decompiler) and the result is the same as in the original JAR. I do not know if this is a bug or a JD application that does it so well that it returns to its original form.

JD-GUI is by definition: a piece of trash for deobfuscation. I don't think you decompiled an obfuscated class or you had it obfuscated very lightly. (Possibly a big bug I missed, but I doubt it.)

Hey! After having had an extremely hard time with ProGuard, I came to this. It'd be great if you could answer couple questions:

1. Does it obfuscate JARs inside a jar?

2. Is it possible to do only flow obfuscation and no name obfuscation? This is so that reflection calls work.

3. Any performance impact of flow obfuscation?

4. How are the stack traces impacted? Followup: If I only do flow obfuscation, what is the impact on stacktraces then?

  1. Nope.

  2. Yes.

  3. There will probably be a little bit of overhead, but that should speed up as the JIT inlines the methods.

  4. Call stack shouldn't be affected.
