Find which of the visible classes implement java. Then you can look at its findClass and findResource implementation. Improve this answer. I can't find the key that i need to unencrypt classes. I forget to mention that i have a lancher. Did you have some suggestion to find the key from there without reverse engineering all calls to jvm in Ida? You'll need to intercept the call that sets the key for decryption. Stepping through with a debugger until it enters the decryption routine should help.

I also had this issue, where I was trying to decompile some java classes but they were all encrypted and I think there is a non obvious solution I would like to mention before I describe how to actually do the decrypting and that is: 1 Try and find an older version of the software that doesn't contain encrypted classes.

If you need to load encrypted class within non-encrypted classes, please use "Thread. This problem has puzzled many users, so, in future releases, I will add a feature to specify the dependency between jar files.

Hide and Encrypt Not protected: If "protect" option not selected, the generated exe file may be extracted by some compress software.

Hello, as in subject. Same holds for a MAC binary executable: without encryption it works fine. Can you help me fixing this issue?
