Building Burp Suite Extensions: Custom JWT Tab Plugins

Security professionals often need tailored tools to handle modern authentication mechanisms efficiently. This text-based course guides you through the process of creating a custom, functional user interface tab within Burp Suite to parse, modify, and encode JSON Web Tokens (JWTs) on the fly. You will start by understanding the foundational API structures required to interact with the Burp Suite framework, establishing a solid conceptual base before writing any code. From there, you will learn to build and organize UI components that integrate seamlessly with your testing workflow. What you'll learn: Understand the core architecture of Burp Suite's extension APIs; Configure custom tab components inside the main user interface; Build input and output handlers to parse and encode JWT payloads; Implement signature validation and modification workflows; Apply modern security testing practices to streamline API assessments. Through clear, step-by-step written explanations and structured code walk-throughs, you will progress from basic setup to a fully operational token manipulation tool. This course is designed for security enthusiasts, penetration testers, and developers who are new to extension development and want to build practical tools from scratch.
