Radare2: Unix-Like Reverse Engineering Framework

See the Releases page for binary downloads. The current git master branch is 5.5.5, and the next release will be 5.6.0.

r2 is a complete rewrite of radare. It provides a set of libraries, tools and plugins to ease reverse engineering tasks.

The radare project started as a simple command-line hexadecimal editor focused on forensics. Today, r2 is a featureful low-level command-line tool with support for scripting. r2 can edit files on local hard drives, view kernel memory, and debug programs locally or via a remote gdb server. r2's wide architecture support allows you to analyze, emulate, debug, modify, and disassemble any binary.

Installation

r2 can be installed via git or pip.

git clone https://github.com/radareorg/radare2
radare2/sys/install.sh

pip install r2env
r2env init
r2env add radare2@git
