![]() How to Read Obfuscated JavaScript JavaScript Obfuscation Reverse Most people try to make their code look organized and easy to read so they can find distinct areas for reference later when changes need to be made. Obtain source code and look for clues such as missing comments or one-letter variables. There is also a keyboard shortcut in Microsoft Edge, Control + U. Go to the main search page and right-click anywhere on the white space. This way, the viewer must sift through the code carefully to understand what is important and how the code actually functions. ![]() What this really does is it has the effect of distracting the viewer with irrelevant content.įor example, if I intend for my code to display a message on the screen, I could add comments that appeared to be code that a viewer thinks is referencing unrelated activities such as language translation. It is possible to format comments in a way that makes them appear to be active code. While compilers read the code and ignore comments, humans typically read comments as they are an easy way to explain the code in simple terms. This technique is another form of trickery. Instead of changing for disguising the names of keywords, the functions that store information can also be obfuscated in the same way. Much like the example above with keywords, the same can be true for variables. If you rename this keyword to vacation, its intent and function would be obscured. In obfuscation, this keyword may be changed to either something unrecognizable or deceptive. They are typically names that are indicative of what action is being taken in the code.įor example, if the keyword is “text”, it likely means that what is to follow is likely a string of characters in word and sentence format much like the page of this article. These are words of phrases that typically stand out to a critical eye. Obviously, this goes beyond simple cartoons and the designs are limitless. For example, if the programmer was a fan, they could arrange letters numbers, and special characters in a specific order to give the effect of a cartoon character of their choosing. they are limited in complexity only based on the imagination of the programmer. This is where the presence or absence of characters creates designs. How to Use JavaScript Obfuscate Obfuscation Techniques Use of Spaces or Lack Thereof What this also means, is that there is a large community of fellow programmers who can be used as a key resource when the time comes to ask for assistance. As a result, security is improved as vulnerabilities are tested and mitigated. This allows for a great deal of input from users. What I believe is the best feature is the fact that it is opensource. This is a great extra that some of the other tools just don’t offer. If it doesn’t work out for any reason you’re not out any money.Īnother great point is that while it obfuscates, it also shrinks and optimizes your code too. ![]() This means there’s no risk for you to try it. ![]() One great thing about ProGuard is it’s free to use. I believe in this case it is because it is the best choice when considering all factors. ![]() Often there is a good reason why so many people choose the same product such as ProGuard. Typically for me, popularity contests are not important. ProGuard is the most popular choice for Java bytecode. ![]()
