fxdchzd/so-decryptor — reverse-engineered prompt

Build me a simple Java command line app that can take a SonOyuncu jar protected with VMProtect for Java and recover a usable decrypted jar so I can inspect the original classes. I want it to accept an input file and an output path, show clear progress, and give friendly error messages instead of crashing.

Please make it handle the common cases you’d expect with this kind of protected jar, and if there are multiple steps needed to unwrap it, do that automatically as much as possible. Keep the project easy to build and run from the terminal, and include a short README that explains how to use it and what limitations or assumptions it has.

I do not need a fancy interface, just something practical that works. If you need more context on the protection format, look up current docs or examples online. This is only for jars I have permission to analyze.
