In computer hardware and software, reverse engineering plays an important role. A program is written in a language, such as C++ or Java that other programmers understand. Before executed on a computer, they must be translated by another program, known as a compiler, into the ones and zeros of machine language. Most programmers cannot understand compiled code, but a decompiler software tool can convert the machine code into a more human-friendly format.
In reverse engineering, data is used for various purposes: to learn, to make new, cheaper products, to improve software interoperability, or to bridge data between different operating systems or databases; to uncover new features of commercial products.
Reverse-engineering can also expose security flaws and questionable privacy practices. With the help of Reverse Engineering, we can modify the software in our way, like can change the name of the Software, We can editing software, We can convert Trial Software to License software, and many more.

Reverse-Engineering Process Work
In software reverse engineering is the process of resolving requirements, specifications, and product functions from code analysis. The information is generated from a database of the program. By doing Reverse engineering in a software for its design or development should be done with legal advice.
The reverse engineering process becomes unnecessary if the information we seek is already available in the public domain, such as the Linux kernel. The purpose of reverse engineering is to:
- Co-operation in Complexity.
- Information recovery.
- They are identifying side effects.
- Higher Abstraction Synthesis.
- Reuse Facility.
Tool For Reverse Engineering
ImHex – Hex Editor For Reverse Engineers
ImHex – A Hex Editor for Reverse Engineers And Programmers Features Featureful hex view Byte patching Patch management. The custom C-like Pattern Language developed and used by ImHex Hex editor is easy to read, understand and learn.
GHIDRA- Free Software Reverse Engineering Framework By NSA
This framework includes a suite of full-featured, high-end software analysis suits that enable users to analyze compiled code on a variety of platforms including Windows, Mac OS, and Linux.
Capabilities include disassembly, assembly, decompilation, graphing, and scripting, along with hundreds of other features. It supports a wide variety of process instruction sets and executable formats and can be run in both user-interactive and automated modes. Users may also develop their own Ghidra plug-in components and/or scripts using Java or Python.
GDA (GJoy Dex Analyzer) – Android Reverse Engineering Suite
GDA is completely self-independent and works without Java VM and installation, so it works well in any newly installed windows system and virtual machine system without additional configuration.
- Android Malware Static Analysis
- File loading and decompiling
- Variable Trace
- XML decoder
- Fully self-implemented decoding function can bypass the Anti-decoding technology, successfully parse XML.
efiXplorer
efiXplorer is IDA plugin for UEFI firmware analysis and reverse engineering automation.
Supported versions of Hex-Rays products: everytime we focus on last versions of IDA and Decompiler because trying to use most recent features from new SDK releases. That means we tested only on recent versions of Hex-Rays products and do not guarantee stable work on previous generations.
Jadx – Dex to Java Decompiler, Android Reverse Engineering Suite
A Command line and GUI suits to convert Java source code from Android Dex and Apk files.
Main features:
- decompile Dalvik bytecode to java classes from APK, dex, aar and zip files
- decode AndroidManifest.xml and other resources from resources.arsc
- deobfuscator included
Rizin – UNIX Like Reverse Engineering Framework
Rizin is free and open-source Reverse Engineering framework, providing a complete binary analysis experience with features like Disassembler, Hexadecimal editor, Emulation, Binary inspection, Debugger, and more.
Rizin is a fork of the radare2 reverse engineering framework with a focus on usability, working features and code cleanliness.
CrowdRE – Crowdsourced Reverse Engineering:
The CrowdRE project aims to fill this gap. Rather than using a live distribution of changes to all clients, which has proven to fail in the past, it leverages from the architecture that is being used with success to organize source code repositories: a system that manages a history of change sets as commit messages.The CrowdRE client is now freely available as an IDA Pro plugin.
CrowdStrike maintains a central cloud for the community to share their commits amongst each other. This basic concept is sufficient for a collaborative workflow on a per-function basis for a shared binary. One exciting feature is a similarity hashing scheme that considers the basic block boundaries of a function. Each function is mapped on a similarity preserving hash of fixed size.

OLLYDBG TOOL: Version 2.01 alpha 2
This tool is mostly used for REVERSE ENGINEERING.
We can make a own license key with the help of it, Any trial version will be a crack from this tool OLLYDBG. The most important novelty is that this version is compatible with Windows 7. I have tested it under Win7 Home Premium 32-bit.

HEX WORKSHOP TOOL:
The Hex Workshop Hex Editor is a set of hexadecimal development tools for Microsoft Windows, combining advanced binary editing with the ease and flexibility of a word processor. With Hex Workshop you can edit, cut, copy, paste, insert, and delete hex, print customizable hex dumps, and export to RTF or HTML for publishing. Additionally you can goto, find, replace, compare, calculate checksums, add smart bookmarks, color map, and generate character distributions within a sector or file. Hex Workshop supports drag and drop and is integrated with the Windows operating system so you can quickly and easily hex edit from your most frequently used workspaces. The Data Inspector is perfect for interpreting, viewing, and editing decimal and binary values. Arithmetic, logical, ascii case, and bitwise operations can be used to help manipulation your data in place.
An Intergrated Structure Viewer allows you to view and edit data in the most intuitive and convenient way.The structure viewer supports nested structures, references to other structures, along with many atomic data types: char, byte, ubyte, word, uword, long, ulong, longlong, float, double, OLE Date/Time, DOSTIME, DOSDATE, FILETIME, and time_t.
