JObfuscator — Java Source Code Obfuscation & Protection (Python Module)
JObfuscator is a source code obfuscator for the Java programming language. It can protect your Java source code and algorithms from hacking, cracking, reverse engineering, decompilation, and technology theft.
JObfuscator employs a variety of obfuscation techniques to protect & conceal the true functionality of your Java source code.
It renames all variables and methods, obfuscates the code flow by making it non-linear, and encrypts all strings with our cutting-edge polymorphic string encryption engine.

It's available for Windows & Linux (requires Mono):

Java decompilation is a huge problem
Applications written in Java and compiled to JAR
, WAR
or CLASS
formats are vulnerable to decompilation.
There are a number of decompilers that can almost completely recreate the compiled code back to Java source.
The problem is that the compiled Java code is written as a so-called bytecode for the JVM (as opposed to the native CPU code like x86
or x86-64
).
In addition to being perfectly perfectly documented, this form of code allows for very accurate reproduction of the original instructions in high-level Java source code.
What can Java decompilers do?
Take a look at this example:
This is decompiled Java code! All the variable, property and method names are readable. You can even easily navigate through the entire decompiled project, jumping from one class to another.
Are you surprised? It could be your software analyzed by the competition, hackers, crackers or anyone else.
Technology & Intellectual Property (IP) Theft
What could they do with it? Most of the time, the software or its algorithms are stolen or replicated in competing products.
In some other cases, the software gets cracked, clearly visible license checks in decompiled source code are patched or even the entire cracked software is recompiled and published on pirate sites.
Java source code obfuscation
Obfuscation is the process of transforming Java source code into a protected version of itself.
The functionality remains unchanged, everything works the same, but the source code and the final compiled bytecode are protected from reverse engineering analysis, even after the decompilation.
Sample Java source code before obfuscation
import java.util.*;
import java.lang.*;
import java.io.*;
@Obfuscate
class Ideone
{
public static double calculateSD(double numArray[])
{
double sum = 0.0, standardDeviation = 0.0;
int length = numArray.length;
for(double num : numArray) {
sum += num;
}
double mean = sum/length;
for(double num: numArray) {
standardDeviation += Math.pow(num - mean, 2);
}
return Math.sqrt(standardDeviation/length);
}
public static void main(String[] args) {
double[] numArray = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };
double SD = calculateSD(numArray);
System.out.format("Standard Deviation = %.6f", SD);
}
}

Would you even be able to tell what the obfuscated code does if you didn't know about the original source code?
Protect your Java projects & algorithms
Take no chances, use JObfuscator to obfuscate and protect your Java projects and algorithms.
Our company has a long history in obfuscation technologies and code obfuscators (see our x86 Assembly & AutoIt obfuscators).
We actively bugfix, research and develop new obfuscation strategies for our tools.
You can count on our expertise and support in this field.
Installation
The preferred way of WebApi interface installation is via pip.
Run:
pip install jobfuscator
or
python3 -m pip install jobfuscator
And then add this import to your source code:
from jobfuscator import JObfuscator
Installation package is available at https://pypi.org/project/jobfuscator/
