Protect & Defend JavaScript Code from Reverse Engineering & Tampering.
JavaScript is a browser intepreted language so it needs to be front end and visible to browsers. Unfortunately, everyone can read it just looking at the source code of the web page your script is running into.
There are two general ways to protect the intellectual property, legally or technically. Legally means getting copyrights or signing legal contracts against creating duplicates etc. And technically means the owners of the software will give the solution for protection with that particular JavaScript code.
Code obfuscation is currently one of the best methods for protecting JavaScript code from reverse engineering. Obfuscation renders software unintelligible but still functionally equivalent to the original code. It also makes programs more difficult to understand, so that it is more resistant to reverse engineering.
Obfuscation is the practice of methodically going through straight-forward source code, renaming variables, transforming and rearranging code, hiding the original algorithm, data structures or the logic of the code, all with the goal of making it virtually impossible to read and understand from prying eyes but working the same way.
With JavaScript Obfuscator your JavaScript code will become impossible to understand thus preventing anyone to steal and modify it.
JavaScript is a scripting programming language so it needs to be front end and visible to browsers. This has several drawbacks and the most important one is that JavaScript source code can be easily viewed by anyone. This means that anyone can steal your JavaScript code, modify it and reuse it for his own purposes. One of the ways to protect your code is to obfuscate it to encrypt the code and make it unreadable.
If you are releasing valuable software and you are not distributing the source code, obfuscation should probably be part of your application development process.
The goal of obfuscation is to make a program 'unintelligible' without altering its functionality, thus making it extremely difficult for a hacker, cracker or competitor to reverse-engineer your application. Obfuscation is often confused with simple method renaming techniques and basic string obfuscation technologies, which can be quickly broken and easily reversed.
JavaScript Obfuscator offers advanced obfuscation techniques, which go far beyond these traditional techniques and consists of many different techniques that can complement each other to create a layered defense. Some typical examples of obfuscation and protection techniques include:
Name obfuscation is the process of replacing the identifiers with meaningless sequences of characters. (Of course, a name obfuscator must process the entire application to ensure consistency of name changes across all files.)
It is the process to change the control flow in a software application. The changed control flow must lead to the same results as the initial one, but produces spaghetti logic that can be very difficult for a cracker to analyze.
Reduces the size of JavaScript files and makes them more efficient, helping application to load faster and reducing bandwidth consumption.
Inserts code that is executed when the program is run but does not affect the semantics of the program, making any disassembled code more difficult to analyze.
Crackers will frequently search for specific strings in your code to locate strategic logic. String Encryption makes this much more difficult to do, because the attacker's search will come up empty. The original string is nowhere to be found in the code. Only its encrypted version is present.
Lock your code based on IP address, domain name and much more. Create trial versions with time limiting and many other features.
To get the most out of JavaScript Obfuscator, you can download and install the full-feature desktop software on Windows computers. JavaScript Obfuscator Desktop provides all the features you need to scramble and protect JavaScript code.
Obfuscating JavaScript files manually one by one can be an irksome and time consuming process. GUI interface tool can help you out in doing a tough and time consuming process in just a few clicks.
