radare2

Radare2 is an open-source command-line reverse engineering tool with features for analyzing and manipulating binary files, including debugging and cryptographic analysis.

Packages and Binaries:

libradare2-5.0.0

The project aims to create a complete, portable, multi-architecture, unix-like toolchain for reverse engineering.

It is composed by an hexadecimal editor (radare) with a wrapped IO layer supporting multiple backends for local/remote files, debugger (OS X, BSD, Linux, W32), stream analyzer, assembler/disassembler (rasm) for x86, ARM, PPC, m68k, Java, MSIL, SPARC, code analysis modules and scripting facilities. A bindiffer named radiff, base converter (rax), shellcode development helper (rasc), a binary information extractor supporting PE, mach0, ELF, class, etc. named rabin, and a block-based hash utility called rahash.

This package provides the libraries from radare2.
