Burp Suite Extension Demo with Montoya API & Java

This project demonstrates how to build a Burp Suite extension using the Montoya API and Gradle in Java. The Montoya API provides a modern interface for creating powerful and efficient extensions for Burp Suite.

Prerequisites

• Java Development Kit (JDK) 17
• Gradle
• Burp Suite (Community or Professional Edition)
• Python3

Getting Started

1. Clone the Repository

git clone https://github.com/Gemei/burp-plugin-demo.git

2. Set Up the Burp Extension Project

Open your preferred Java IDE and import the directory Request_Encryption_Handler_Demo as a project3. Build the Extension

Use Gradle to build the project:

gradle clean build

The final JAR will be located under:

build/libs/Request_Encryption_Handler_Demo-1.0.jar

3. Load the Extension into Burp Suite

1. Open Burp Suite.
2. Go to the Extender tab → Extensions sub-tab.
3. Click Add.
4. Set Extension Type to Java.
5. Select your generated .jar file from the build/libs/ directory.
6. Load the extension.

If everything is correct, Burp will show your extension as Loaded Successfully.

• libs/: Directory for external JARs like Montoya API (if needed).

4. Start the web application

Go to the py_web directory and run pip

pip install requirements.txt

Then run the web application using python3

python3 main.py
