Bipbap

Bipbap is a lightweight JVM obfuscator with ready-to-use presets, a Swing UI, JSON configuration support, and Android Gradle Plugin integration.

It can be used as:

• a command line jar obfuscator
• a desktop UI tool
• a JVM desktop application Gradle Plugin
• an Android Gradle Plugin that runs before R8/ProGuard

Highlights

• Presets for quick usage: -low, -mid, -high
• JSON config generation and loading
• Swing UI, launched by double-clicking the jar or using -ui
• JVM desktop application obfuscation through Gradle
• Android app/library obfuscation through the Android Gradle Plugin Variant API
• ProGuard/R8-compatible Android mode enabled by default
• Generated keep rules for Bipbap Android output

Command Line Usage

Launch the UI:

java -jar bipbap.jar -ui

Launching without arguments also opens the UI:

java -jar bipbap.jar

Generate a default config:

java -jar bipbap.jar -genconfig config.json

Run with a config:

java -jar bipbap.jar config.json

Run with a preset:

java -jar bipbap.jar -low
java -jar bipbap.jar -mid input.jar
java -jar bipbap.jar -high input.jar output.jar

Preset input/output defaults:

Command	Input	Output
-high	input.jar	output.jar
-high input.jar	input.jar	input-obf.jar
-high input.jar output.jar	input.jar	output.jar

Additional CLI options:

Option	Description
-mt:4	Use 4 worker threads
-mt or -mt:-1	Use Runtime.availableProcessors()
-auth=https://example.com	Configure HWID authentication endpoint

JVM Gradle Plugin

Bipbap supports desktop Java/Kotlin JVM application obfuscation through its Gradle plugin. The plugin reads the project's jar output and writes a separate obfuscated jar without replacing the original artifact.

See the full JVM Gradle guide: JVM Gradle Plugin Usage.

Android Obfuscation

Bipbap supports Android app/library obfuscation through its Gradle plugin. The plugin runs before R8/ProGuard, uses Android-safe defaults, and can generate keep rules for Bipbap's encrypted constant layer.

See the full Android guide: Android Gradle Plugin Usage.
