Features

String Encryption

qProtect employs advanced encryption techniques to protect sensitive strings within your code, making it extremely difficult for attackers to extract valuable information.

Reference Encryption

Field and method calls are encrypted, thwarting attempts to trace and understand critical interactions within your codebase.

Flow Obfuscation

By introducing complex control flow structures and opaque predicates, qProtect obscures the logical flow of your code, making it challenging to comprehend and analyze.

Number Obfuscation

qProtect transforms numerical values using arithmetic obfuscation techniques, making it arduous for attackers to understand the actual values and their purposes.

Anti-Debugging Code Injection

qProtect enhances the security of your application by injecting anti-debugging mechanisms, making it harder for attackers to analyze and manipulate your code during runtime.

Resource Encryption

qProtect encrypts resources, such as images or configuration files, preventing unauthorized access and extraction.

Decompiler Crashers

qProtect provides crashers specifically designed to disrupt popular reverse engineering tools like JByteMod and Recaf, adding an extra layer of protection to your code.

Debug Information Remover

Removes debug information such as local variable names and line numbers from your Java application.

Access Obfuscation

Obfuscates fields, methods, and class access values to make reverse engineering significantly harder.

Renamer (Experimental)

Renames classes, methods, and fields to obscure code and resist reverse engineering. (Experimental)

Custom Transformers

Create your own transformers using a simple API and implement personalized obfuscation techniques.

Modern UI

A sleek and intuitive interface for an effortless user experience.

Maven Plugin

Seamlessly integrates into your workflow with automatic obfuscation during builds.

Exceptional Support

Fast and reliable support with responses typically within minutes.
