https://github.com/radareorg/radare2-bookCommunity-maintained documentation for radare2, including guides on code analysis, function management (af commands), cross-references (ax commands), and calling conventions (afc commands). It also contains technical details for the r2png utility and instructions for customizing the physical book cover layout and spine width.
R2Wars is a programming duel environment where two programs compete in a shared virtual memory space. The objective is to overwrite the opponent's code to cause a crash. Players use real assembly languages and must be proficient with the radare2 toolchain.
The official, high-performance implementation used in r2con competitions is written in C# and can be found at: https://github.com/radareorg/r2wars
radiff2 is a tool within the radare2 suite used for comparing binary files. It supports various diffing methodologies including 1:1 binary diffing, delta diffing, code analysis diffing, and binary data (bindata) diffing. It can compare files at multiple levels, from raw data to disassembled code, and supports architecture/bits specification and graph diffing.
Many radiff2 features are also available as the c command within the radare2 shell, allowing you to compare data from disk or process memory without leaving your current session.
rasm2 is a command-line tool within the radare2 framework used for both assembling (converting assembly code to machine code) and disassembling (converting machine code to assembly). It is a standalone tool that supports multiple architectures, flexible input/output formats (hex, binary, text), and shellcode generation.
Key capabilities:
r2pm is the dedicated package manager for Radare2, used to manage external plugins and tools that integrate closely with the Radare2 ecosystem.
Key characteristics:
-gi flag for system-wide installation (requires sudo).ragg2 is a tool used to compile relocatable code snippets (eggs) into tiny binaries for x86, x86-64, and ARM architectures. It is primarily used for generating shellcode for exploitation tasks. It supports compiling both its own domain-specific language and standard C code (via GCC or Clang depending on file extensions).
Key capabilities include:
Radare2 provides several ways to automate tasks and extend its functionality:
r2frida is a plugin that integrates radare2 with Frida, enabling dynamic analysis and instrumentation of running processes. It allows you to use radare2's mnemonic commands to execute logic inside a target process instead of writing manual JavaScript one-liners. This integration allows you to import dynamic instrumentation data directly into your radare2 static analysis environment.
Key capabilities include:
:. command.Rarun2 is a tool used to set up a specific execution environment for a binary. It allows you to redefine stdin/stdout, manage pipes, modify environment variables, and configure other settings to create controlled boundary conditions for debugging and reverse engineering.
It can be used as a standalone tool or integrated into radare2 using the following flags:
-r <file>: Load a profile from a file.-R <string>: Specify the profile directives directly from a string.$ rarun2 -h
Usage: rarun2 -v|-t|script.rr2 [directive ..]r2png utility automates the creation of PNG images for documentation by executing a specific list of radare2 commands and capturing the output as a screenshot. This eliminates the need to manually maintain image files when command outputs change.The rax2 utility is a minimalistic expression evaluator for the shell. It is used for mathematical calculations, base conversions (hex, octal, binary, decimal, ternary), and handling data formats like Base64, ASCII, and endianness.
Inside the radare2 framework, you can access rax2 functionality using the ? command.
The base of a number is determined by its prefix or suffix:
30xface04722M (e.g., 2 megabytes)1100011b (suffix b)1010dt (suffix dt)3.33f (suffix f)# Inside radare2
[0x00000000]> ? 3+4
# From the shell
$ rax2 3+0x80
