Reverse Engineering

Reverse-engineering is especially important with computer hardware and software. Programs are written in a language, say C++ or Java, that's understandable by other programmers. But to run on a computer, they have to be translated by another  program, called a compiler, into the ones and zeros of machine language. Compiled   code is incomprehensible to most programmers, but there are ways to convert    machine code back to a more human-friendly format, including a software tool          called a decompiler.

Reverse-engineering is used for many purposes: as a learning tool; as a way to make new, compatible products that are cheaper than what's currently on the market; for making software interoperate more effectively or to bridge data between different operating systems or databases; and to uncover the undocumented features of commercial products. 

Reverse-engineering can also expose security flaws and questionable privacy practice

With the help of Reverse Engineering we can modify a software at own way... Like we can change the name of Software, We can editing a software, We can convert Trial Software to License software... n many more. 
So Reverse Engineering is a hacker friendly tool.... Use it n Enjoy..!!


Tools >>

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 changesets 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.
