Java Source Code Obfuscator - JObfuscator

Obfuscate your Java source code & algorithms to protect it against reverse engineering analysis, cracking, and decompilation.

JObfuscator is a Java source code obfuscator to protect your work at the source code level. After compilation of the protected and obfuscated code - it will be extremely hard to reverse engineer the compiled bytecode, forget about Java decompilers!

Changes:

v1.10 - 09.08.2022

• Fixed an error in the order of variable declarations when using obfuscation to change the linear path of code execution (thank you Yi Wu)
• Automatically adding special annotation for IntelliJ IDE @SuppressWarnings(InstanceVariableMayNotBeInitialized) for the non-linear code path obfuscation

v1.09 - 06.02.2022

• Fixed bug in annotation handling that caused string encryption obfuscation to work incorrectly

v1.08 - 19.10.2021

• Fixed renaming methods within the same class

v1.07 - 17.08.2021

• Improved integer to arrays obfuscation by generating multidimensional arrays e.g. int[][] var_3035 = { { 65535 }, { 01, 02, 0b0 } };
• Improved doubles to arrays obfuscation by generating multidimensional arrays e.g. double[][][] O_ZzBf7_4tcNvh_c = { { { 2.8 } }, { { 1.3 } }, { { 0.06, 3.7, 65535.8 } } };

Best Java Obfuscator?

Our Java Obfuscator - JObfuscator has been updated to include new Java obfuscation strategies.

Obfuscation engine history

v1.03 - 31.07.2021

• Some integers were not extracted correctly for the integers to arrays obfuscation strategy
• Multilevel obfuscation of extracted integers into the arrays (into a random number of double and integer arrays)

v1.02 - 30.07.2021

• An integers to arrays obfuscation strategy, converts the integer values into double values to avoid deobfuscation by popular Java decompilers e.g. double[] var_2597 = new double[]{13.898355719807563D, 65535.73657403742D, ... };

v1.01 - 28.07.2021

• A new obfuscation strategy. For each method, extract all possible integers from the code and store them in an array. It makes the analysis harder because it requires an indexed table lookup for every numeric value.

Client history

v1.01 - 28.07.2021

• All clients (Windows, Linux) and SDKs (PHP & Python) updated to include the new obfuscation strategy /IntsToArrays
