Technology Stack:
Radare2 is primarily written in the C programming language, which allows for efficient binary analysis and manipulation. It leverages the power and speed of C to provide a performant and versatile framework. Additionally, Radare2 utilizes a modular design, allowing users to extend its functionality through plugins.
The framework also incorporates various other technologies and libraries, including Capstone (a disassembly engine), Unicorn (a CPU emulator), and LibR (Radare2's own library for binary analysis). These technologies contribute to the project's success by providing powerful and reliable tools for the reverse engineering process.
Project Structure and Architecture:
Radare2 follows a modular architecture that allows for flexibility and extensibility. The framework consists of several components, including a command-line interface (CLI), a graphical user interface (GUI), and a powerful library for programmatic access.
The CLI is the primary interface for interacting with Radare2, providing a command-line prompt for executing commands and analyzing binaries. The GUI, known as Cutter, is an optional component that provides a graphical user interface for the framework.
Radare2's core functionality is built upon a shared library called LibR. This library provides a set of APIs and abstractions that allow users to programmatically interact with the framework. It also serves as the foundation for various plugins and extensions that further enhance Radare2's capabilities.
The project follows a modular design, where functionalities are divided into plugins. This modular design allows users to selectively load only the necessary plugins, reducing memory overhead and improving performance. It also allows for easy integration of third-party plugins and extensions.
