radare2 5.4.2 releases: unix-like reverse engineering framework and commandline tools

Introduction

r2 is a rewrite from scratch of radare in order to provide a set of libraries and tools to work with binary files.

Radare project started as a forensics tool, a scriptable command-line hexadecimal editor able to open disk files, but later support for analyzing binaries, disassembling code, debugging programs, attaching to remote gdb servers, …

radare2 is portable.

The main tool of the whole framework. It uses the core of the hexadecimal editor and debugger. radare2 allows you to open a number of input/output sources as if they were simple, plain files, including disks, network connections, kernel drivers, processes under debugging, and so on.

It implements an advanced command line interface for moving around a file, analyzing data, disassembling, binary patching, data comparison, searching, replacing, and visualizing. It can be scripted with a variety of languages, including Python, Ruby, JavaScript, Lua, and Perl.
