Reverse engineering is taking apart an object to see how it works in order to duplicate or enhance the object. The practice, taken from older industries, is now frequently used on computer hardware and software. Software reverse engineering involves reversing a program’s machine code (the string of 0s and 1s that are sent to the logic processor) back into the source code that it was written in, using program language statements.
It is being widely used in computer hardware and software to enhance product features or fix certain bugs. For example, the programmer writes the code in a high-level language such as C, C++ etc.
As computers do not speak these languages, the code written in these programming languages needs to be assembled in a format that is machine specific. In short, the code written in high level language needs to be interpreted into low level or machine language.
The process of converting the code written in high level language into a low level language without changing the original program is known as reverse engineering. It’s similar to disassembling the parts of a vehicle to understand the basic functioning of the machine and internal parts etc. and thereafter making appropriate adjustments to give rise to a better performing or superior vehicle.
