Radare2
Analyze and reverse engineer software with radare2, a Unix-like framework and command-line toolkit.
About Radare2
Radare2 is a UNIX-like reverse engineering framework and command-line toolset that provides libraries, tools and plugins for working with binaries. It can analyze, disassemble, emulate, debug and modify binaries, edit files on local drives, view kernel memory, and debug locally or via remote gdb and windbg servers. Tasks can be scripted with the embedded JavaScript interpreter or via r2pipe.
Additional function is added through the r2pm tool, including decompilers and binary-diffing support. Windows builds require meson with msvc or mingw, and individual plugins can have licenses different from the LGPLv3 distribution.
