radare2

Radare2 (also known as r2) is a complete framework for reverse-engineering and analyzing binaries; composed of a set of small utilities that can be used together or independently from the command line. Built around a disassembler for computer software which generates assembly language source code from machine-executable code, it supports a variety of executable formats for different processors and operating systems. Apart from the static analysis feature it also supports debugging and emulation. The architecture of the framework is modular and allows to use existing or create new plugins for new file formats, architectures, analysis features.
