2LKit Obfuscator - Version 1.1 It is a well known fact that Java Class files can be easily decompiled into the original source. To protect your hard work and prevent someone from stealing your intellectual property, you need a Java class obfuscator. 2LKit Obfuscator changes class's, method's, field's and package's names, removes unused class attributes. Resulting classes are smaller (15-35% reduction), can be loaded faster and they have less information when decompiled.
