Java Source Code Obfuscator

The Java Obfuscator tool scrambles Java source code to make it very difficult to understand or reverse-engineer (example). This provides significant protection for source code intellectual property that must be shipped to a customer, and against the all-too-easy disassembly of Java class file object code. You only need to expose the public API that your classes offer to your customers; all your internal APIs and class names become inscrutable. It is a member of SD's family of Source Code Obfuscators.

"I spent the day testing out several obfuscators and yours was by far The Best!!! The others made only very minor changes and left the code pretty clear. Yours did a super job of obfuscating the code."
