Reverse Engineering is an art, at least that’s what they say. In IT Industry, Reverse Engineering is quite common word now-a-days. Let’s take a leap into what is real meaning of reverse engineering.
According to Wikipedia,
“Reverse engineering is the process of discovering the technological principles of a device, object, or system through analysis of its structure, function, and operation.”
For scope of this article, we will only focus on reverse engineering of software, hardware or device is altogether with different practice. If you are software engineer and you found any very good software which is extremely good, you want to implement the same kind of functionality or you need inspiration (I won’t say copy!) then how you can access source code of that software? Of course unless it’s open source, it’snot possible to ask author or company who built the software for permission to look into the source code.
There are several benefits of Reverse engineering. You can solve any bug of software, you can improve its functionality, and you can see how program operates. At the same time, there are some complications of reverse engineering. There can be legal complication if software is proprietor of any company, or if you reverse engineer any application to solve some bugs or improve its functionality without understanding the complete flow of application, then you can introduce new bugs which will be very hard to track.
