Obfuscator

Simple, basic obfuscator that was intended for commercial use but is no longer used.

The obfuscator was originally intended to be a private, experimental obfuscator for testing & learning purposes.

The codebase of this software is very poor, and I no longer maintain this code as I have made a rewrite.

I would strongly advise you do not use this obfuscator to obfuscate your code as it is very basic. Every feature can be easily removed with methods such as static analysis.

Usage

gradlew build

You will find your built jar in build/libs.

To run the obfuscator: java -jar file.jar settings.json input.jar output.jar

Configuration

{
  "ignoreJarEntries": [],
  "modId": "MinecraftModID",
  "validObfPackages": [
    "club.cpacket.client"
  ],
  "excludeObfClasses": [
    "^club\\.cpacket\\.client\\.MainModClass$"
  ],
  "excludeObfAnnotations": [],
  "obfPackage": "club.cpacket.client",
  "obfPackageMapping": [],
  "enableClassObf": true,
  "enableFieldObf": true,
  "enableMethodObf": true,
  "enableLocalObf": true,
  "obfNameFormat": "RANDOM",
  "removeKotlinMetadata": true,
  "removeSignatures": true,
  "removeSourceInfo": true,
  "hideClassMembers": true,
  "eventAnnotations": [],
  "numbersAsExpressions": true,
  "removeLineNumbers": true,
  "stringMangling": true,
  "stringEncryption": false,
  "fieldValueOverrides": {},
  "storeEncryptedClasses": false,
  "excludeEncryptionClasses": [],
  "mixinPackage": "club.cpacket.client.mixin",
  "numbersAsExpressionsWithSeed": true,
  "addFunctionIndirections": true,
  "useInvokeDynamic": false,
  "criticalPerformanceClasses": []
}

Some of these options do not work due to bugs or are depreciated as they are commented out in the code.

You are advised to run this obfuscator on java 11 as this was the main version of java this software was developed with, however it supports java 8 through to 13. (Newer versions have not been tested.)

No support will be provided, and this project will not be maintained. Feel free to fork it and maintain your own versions. I have just released it so others can learn a thing or two if they want to get into java obfuscation. (You shouldn't though. :P)
