Description:

The radare project aims to provide a complete unix-like toolchain for working with binary files. It currently provides a set of tools to work with x86, arm and java with some ones powerpc.

The core is a raw hexadecimal editor for commandline with scripting features and perl/python extensions that gets extended with IO plugins that hooks the open/read/write/close/system calls.

The debugger and disassembler has a code analysis module for x86, arm and java. This way it's possible to draw graphs using Cairo on a GTK window or store the flow execution of a program on a log file and use the information to diff't against another trace or binary.

The toolchain provides assemblers and disasemblers for x86, arm and java.

The disassembler has been enhaced to handle inline comments, code block detections and flag references (data pointers or so).

The debugger currently works on linux,*bsd x86-32 but it has initial support for x86-64 and linux-ARM, and w32 support is in mind too.

But there are IO plugins for debugging windows and DOS applications via wine and dosemu. Initial gxemul support gives us the possibility to also debug ARM, MIPS, SPARC, .. binaries.

There are some internal commands to handle memory maps, mount a syscall proxy, inject code, patch data, dump user data sections, step-back, syscall tracing, hardware DRx register manipulation, conditional watchpoints with expressions, signalling manipulation, syscall injection and very early threading support..

Data structures can be parsed with hand-written C programs called as extensions from radare. So the hexadecimal editor comes with a set of views for different bases and print formats like URL-encoding, binary, octal, shellcode, C string-like, which is really useful for developing shellcodes.

There's a minimal GUI frontend written in C that interacts directly with an VTE running radare. But I plan to write a new native frontend written in Vala.

Current development plugins are:

* ewf: EnCase (R) forensic disk images
* winedbg: WineDebugger interface ( winedbg://./program.exe )
* haret: Remotely read WindowsCE memory ( haret://host:port )
* ptrace: Debugs or attach to a process ( dbg://file or pid://PID )
* sysproxy: Connects to a remote syscallproxy server
* remote: TCP IO ( listen://:port or connect://host:port )
* gdb: Debugs or attach to a process using gdb (gdb://file, gdb://PID, gdb://host:port)
* w32: posix to native w32 api io
* posix: plain posix file access

The tools provided around the core are:

* radare: command line hexadecimal editor with IO plugin extensions
* rabin: get info from ELF/MZ/PE/CLASS files
* rasc: shellcode generator and tester (outputs in raw, hexpairs or C)
* bindiff: binary diffing utilities for raw files, binaries, data blocks, etc
* xrefs: find crossed references on raw images for ppc, arm and x86
* hasher: calculate different algorithms over data blocks of a file or stream
* rsc: command line helpers written in shellscript or perl
* javasm: minimalistic java assembler/disassembler/classdumper
* armasm: minimalistic arm assembler
* xc: converts between multiple radix numeric bases
