Open Source Java Obfuscators for ChromeOS

Mixin is a trait/mixin framework for Java using ASM and hooking into the runtime classloading process via a set of pluggable built-in or user-provided services. Built-in services currently support Mojang's LegacyLauncher system, though this is deprecated in favor of ModLauncher by cpw, which has greater extensibility and has support for Java 8 and later. Additional documentation for individual features and annotations can be found in the extensive Javadoc. For additional help use the channel #mixin on the Sponge Discord Server. For handling obfuscation tasks, Mixin provides an Annotation Processor which works at compile time to generate obfuscation mappings for your toolchain to apply. If using Gradle 5 or later, annotation processors are no longer automatically loaded from compile configurations and must be specified explicitly via annotationProcessor configurations.

ProGuard has moved to Github now: https://github.com/Guardsquare/proguard ProGuard is a free Java class file shrinker, optimizer, obfuscator, and preverifier. It detects and removes unused classes, fields, methods, and attributes. It optimizes bytecode and removes unused instructions. It renames the remaining classes, fields, and methods using short meaningless names. ProGuard is useful for making code more compact and more efficient, on the desktop, on tablets, on smartphones, and on embedded devices. It also makes code more difficult to reverse engineer.

The project provides a set of Ant tasks for developing J2ME/MIDP applications based on the J2ME Wireless Toolkit. The new tasks allow for compilation, preverification, packaging, and obfuscation of a MIDlet suite as well as for making a PalmOS PRC file.

JavaGuard is a general purpose bytecode obfuscator, designed to fit effortlessly into your regular build and testing process, providing peace of mind that your valuable Java code is more secure against decompilation and other forms of reverse engineering

JODE is a java package containing a decompiler and an optimizer (aka obfuscator ;-) for java.

An API and a graphical tool for inspection (viewing, searching and comparing) and manipulation (modification, obfuscation, refactoring of methods, fields, attributes and code) of classfiles for the Java platform.

HDLObf is intended to be a HDL Obfuscator and identifier name change utility. Primarily designed for Verilog/SystemVerilog support will be added for VHDL/SystemC in future.

JEST will be the Java bytecode engineering Swiss-Army Jackhammer. It will include a disassembler, class browser, obfuscator, optimizer, class editor, and bytecode debugger, and have an intuitive GUI.

JarSpy - The Java Archive Spy. JarSpy provides insight into the contents of Java archive files (.jar, .zip, .ear, .war etc.). Eventually, JarSpy will provide the ability to modify the contents of Java archive files for instrumentation, obfuscation etc.

Yet another Java obfuscation tool. This one has a bit of a different twist, in that it can obfuscate native methods by generating a .h file which #defines the original method names to the obfuscated ones. Built with Apache BCEL.

Obclipse manage the obfuscation of an ready build eclipse product. It collects the necessary information of a product, configure a third party obfuscator, obfuscate the product and fixes the textual files of the plugins by the obfuscated class names.

obfuscate4e is an Eclipse feature to obfuscate plugins during their export. This feature provides an integrated proguard obfuscator, other obfuscators might be added as plugins. The project moved to http://code.google.com/p/obfuscate4e/
