Radare2

Radare2 is a free and open-source framework for reverse engineering, binary analysis, and software exploitation. Originally created by pancake in 2006, it provides a comprehensive suite of tools for analyzing binary files across multiple architectures and platforms. The framework is written in C and can be extended with various plugins and bindings for different programming languages.

The core of radare2 is the command-line interface that allows users to interact with binary files through a set of commands. It features disassemblers, debuggers, emulators, and various utilities for binary analysis. The framework supports multiple file formats including ELF, PE, Mach-O, and raw binaries. It can be used for tasks such as vulnerability research, malware analysis, software auditing, and general reverse engineering.

Radare2 is highly customizable through its r2pipe interface, which enables integration with other tools and scripting languages. The project has an active community that contributes plugins, documentation, and tutorials. While it has a steep learning curve due to its command-line nature and extensive feature set, it is considered a powerful alternative to other reverse engineering tools like IDA Pro and Ghidra.
