Radare2: Unix-Like Reverse Engineering Framework

Next release will be 5.4.0 and the See the Release downloads page.

r2 is a rewrite from scratch of radare. It provies 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, over time more features were added to support a scriptable command-line low level tool to edit from local hard drives, kernel memory, programs, remote gdb servers and be able to analyze, emulate, debug, modify and disassemble any binary.

Install r2 from Git (Clone the repo and run sys/install.sh) or use pip install r2env
