r2 is a complete rewrite of radare. It provides a set of libraries, tools and
plugins to ease reverse engineering tasks. Distributed under LGPLv3, despite
each plugin can have different licenses (see r2 -Lj for details)
The radare project started as a simple command-line hexadecimal editor focused on forensics. Today, r2 is a full-featured low-level command-line tool with support for scripting with the embedded Javascript interpreter or via r2pipe.
r2 can edit files on local hard drives, view kernel memory, and debug programs locally or via a remote gdb/windbg servers. r2's wide architecture support allows you to analyze, emulate, debug, modify, and disassemble any binary.
Download the last released binaries.
The recommended way to install radare2 is from Git repository source:
git clone https://github.com/radareorg/radare2
radare2/sys/install.sh- Run
sys/install.shfor the default acr+make+symlink installation - meson/ninja (muon/samu also works) and make builds are supported.
- r2 can be installed from
gitor viapipusingr2env. - Windows builds require meson and msvc or mingw as compilers
- To uninstall the current build of r2 run
make uninstall - To uninstall ALL the system installations of r2 do:
sudo make purge
On Windows use the .bat scripts and msvc:
preconfigure.bat REM setup python, meson, ninja
configure.bat REM run meson b + vs project
make.bat REM run ninja -C b
