RetroGuard for Java Bytecode Obfuscation

The Java(tm) class file format exposes an enormous amount of information about your original Java source code. Using one of the many decompilers on the market, Java class files can be accurately converted back into source format. Your code is therefore open to review and decompilation by competitors and to unauthorized modification and redistribution.

Get the RetroGuard obfuscator through our downloads page, and then review the documentation to learn how to apply Java obfuscation to your software. The RetroGuard for Java bytecode obfuscator is distributed under several licensing options:

• If you are commercial, purchase RetroGuard Pro under an annual license and support agreement for $139 per year.
• If you are academic or not-for-profit, use RetroGuard Lite under a non-commercial license.

Written in Java (compliant with Java SE 6 and earlier versions back to JDK-1.1). Designed to be integrated seamlessly into your regular build and quality-assurance process. The RetroGuard obfuscator is driven by a simple script file, with sensible defaults for all Java obfuscation options. RetroGuard has been rigorously tested to ensure, after Java obfuscation, the classes will perform identically to the original.

The RetroGuard bytecode obfuscator modifies the contents of your class files in such a way that their behaviour is unaffected, while minimizing the amount of information from the source code that is exposed. A side effect of RetroGuard obfuscation is that the class size is reduced, leading to faster download times for your Java products.
