# 1.2 Overview

Nowadays the project is composed by a set of small utilities that can be used together or independently from the command line:

    radare

The core of the hexadecimal editor and debugger. Allows to open any kind of file from different IO access like disk, network, kernel plugins, remote devices, debugged processes, ... and handle any of them as if they were a simple plain file.

Implements an advanced command line interface for moving around the file, analyzing data, disassembling, binary patching, data comparision, searching, replacing, scripting with ruby, python, lua and perl, ...

    rabin

Extracts information from executable binaries like ELF, PE, Java CLASS, MACH-O. It's used from the core to get exported symbols, imports, file information, xrefs, library dependencies, sections, ...

    rasm

Commandline assembler and disassembler for multiple architectures (intel[32,64], mips, arm, powerpc, java, msil, ...)

    $ rasm -a java 'nop'
    00
    $ rasm -a x86 -d '90'
    nop

    rasc

Small utility to prepare buffers or shellcodes for exploiting vulnerabilities. It has an internal hardcoded database of shellcodes and a syscall-proxy interface with some nice helpers like fill-with nops, breakpoints, series of values to find the landing point, etc..

    rahash

Implementation of a block-based rahash for small text strings or large disks, supporting multiple algorithms like md4, md5, crc16, crc32, sha1, sha256, sha384, sha512, par, xor, xorpair, mod255, hamdist or entropy.

It can be used to check the integrity or track changes between big files, memory dumps or disks.

    radiff

Binary diffing utility with multiple algorithms implemented inside. Supports byte-level or delta diffing for binary files and code-analysis diffing to find changes in basic code blocks from radare code analysis or IDA ones using the idc2rdb rsc script.

    rsc

Entrypoint for calling multiple small scripts and utilities that can be used from the shell.
