Enigma
Fork history
Enigma seemed kinda crash happy to me when I was using it, so I looked around for more updated versions with less bugs. That brought me to the fork written by jeanthom.
I'm forking it for the purpose of adding a string decryption hotkey. This feature won't add anything to the mappings (and who knows, the decrypted strings may break other features!).
Old Readme Contents
Enigma is "a tool for deobfuscation of Java bytecode" : you can use it to edit method or class names inside a .jar file.
Enigma was originally a project from Cuchaz Interactive. It was meant to help reverse engineer Minecraft jar binaries.
I have decided to fork it because it had a NULL-pointer exception bug when handling certain functions (a critical one in my case...), and also the gradle dependencies were not up to date. The original README is kept intact in this repository.
Build
In order to build Enigma, you need to have OpenJDK development tools and gradle installed.
Note: New versions of gradle won't work. Gradle 2.14.1 is the version that I finally got to work
I installed gradle by doing the following:
Install gradle
Install SdkMan
Website with directions and details: https://sdkman.io
Basically boiled down to:
curl -s "https://get.sdkman.io" | bash
source "$HOME/.sdkman/bin/sdkman-init.sh"
sdk install gradle 2.14.1
Building Enigma
I already had JDK installed. It was having issues with the default versions, so I had it use 1.8 HotSpot version by controlling the path environment variable before calling gradle
PATH=/opt/jdk1.8.0_102/bin:$PATH; gradle clean
PATH=/opt/jdk1.8.0_102/bin:$PATH; gradle build
PATH=/opt/jdk1.8.0_102/bin:$PATH; gradle jar
Build files are located in build/libs/. enigma-0.10.4b-all.jar is the one you are looking for :-)
