Flatcode Java Obfuscator

Altering code in order to protect its integrity is one of the multiple tactics deployed in order to safeguard data from hacking. The obfuscation process is one such tool for modifying Java bytecode, be it executables, or libraries, in order to decrease decryption susceptibility. This can be achieved using specialized tools, which address the prevention of reverse engineering, such as Flatcode Java Obfuscator.

This application was created specifically in order to provide users with the means to perform obfuscation for Java-based applications, which were written in Java versions 1.4 to 1.8. The main working principle behind the app, relies on deploying the control-flow flattening for the Java byte code obfuscation.

The method’s flow is being controlled by feeding the information encryption directly into the switch statement, and the run-time decryption for the flow dispatching of information is carried out using DLL files appended to the software.

Java instrumentation is used for subsequent runs restoration when dealing with post-obfuscation modification of class byte codes and the String constants are encrypted, as well as the property files, which are adapted to the renamed classes.

Last but not least, users will have the choice of selecting the preferred obfuscation method, and opt for renaming without code flattening.
