What are code obfuscation and its uses? – What is obfuscation?

An Application obfuscation refers to a set of technologies used to protect an application and its embedded intellectual property (IP) from application-level intrusions, reverse engineering, and hacking attempts. It's really important for any company going into business with smart contract or app development. So what is Obfuscation?

What is Obfuscation?

Obfuscating a text means to make the texts difficult to comprehend or understand. Certain programmers might do this to protect their software against attackers that could reverse engineer it for access to the intellectual property inside.

Some of the different approaches to obfuscating code would be to remove any revealing metadata, replace class and variable names with meaningless labels, and adding unused or meaningless code. A tool called the obfuscator is a great way to protect your source code or even make it work in a different way. The content of your code is converted into something that's harder to read and understand, while doing the same job at hand.

There have been recent instances where malware writers use similar methods to avoid detection by anti-malware tools. The 2020 SolarWinds attack is an example of hackers using perturbation to evade defenses.

Decryption methods include 'slicing' a program. This involves blocking out anything that is not relevant to what is happening in the current line of code, rather than scanning through many lines of code at once. Compilers and program synthesis are just two of the many methods that might be used to decrypt a message. Code obfuscation is used to make reverse engineering difficult, if not impossible.
