GptHidra is a Ghidra plugin designed to enhance reverse engineering workflows by leveraging OpenAI's GPT models to automatically generate explanations for functions. It targets Ghidra users, including reverse engineers and security researchers, enabling faster comprehension of complex codebases by providing AI-generated insights into function behavior.

How It Works

The plugin integrates with Ghidra's decompiler interface. Upon user selection of a function, GptHidra extracts relevant decompiled code and context, then sends this information to the OpenAI API. The GPT model processes the code and returns a natural language explanation, which is then displayed within the Ghidra console. This approach automates the often time-consuming process of manually analyzing and documenting unfamiliar functions.

Quick Start & Requirements

• Install: Save GptHidra.py to Ghidra's script manager.
• Prerequisites: Ghidra >= 10.1.5, OpenAI Chat GPT API key.
• Setup: Requires pasting API key into the script.
• Docs: Ghidra API, OpenAI API

Highlighted Details

• GPT-4 integration for enhanced explanation quality.
• Function explanation via keyboard shortcut (Ctrl+Alt+G) or menu item.
• Explanations are output directly to the Ghidra console.

Maintenance & Community

• Contact: Telegram @evyatar9, Discord evyatar9.
• Contributions are welcomed via pull requests or issue reports.

Licensing & Compatibility

• License: Not explicitly stated in the README.
• Compatibility: Requires Ghidra and OpenAI API access. Commercial use depends on OpenAI's API terms and the unstated license of the plugin itself.

Limitations & Caveats

The plugin's functionality is dependent on the availability and performance of the OpenAI API, and costs may be incurred based on API usage. The license for the plugin is not specified, which may impact commercial use.
