Immediate parsing has its perks but it also comes with major downsides. As the source code is easily visible, everyone can read it. This can cause major security risks and hence the code needs to be protected.
Since you can’t hide your code but you can make it difficult to read for the user. But, if your code is easily readable and understandable to the user, the chances of your code being copied will be high. So, for this a number of techniques are used to alter your code without changing the functionality. The two most popular ways are:
First we will see what obfuscation is and tools available for it.
What is Obfuscation
Obfuscation is the technique of going through your source code, changing the variables and rearranging them, breaking the application logic and hiding the original algorithm.
An obfuscated code is difficult to understand and hence decreasing the security risk. Although the code can be deobfuscated, it’ll leave users with meaningless variables and hard to understand logic, with no comments, making it useless on large scale projects.
Let’s look at them one by one, and the features they provide:
Another tool available for this purpose is Uglify, that makes the program “unintelligent” without altering the functionality. Goal is to make it unreadable by compressing and renaming the variables and functions. It’s also irreversible.
Jscrambler increases the security of your code by adding various protecting layers like code locks and self-defending capabilities. Thus, making it unreadable for any stealer or hacker.
What is minify
Minify, also known as minification, is simply compressing your code in such a way that it removes all unnecessary characters without changing the functionality. These characters include white spaces, comments, unnecessary parenthesis or variable declaration etc. This makes the code difficult to understand and hence decreasing the risk of being copied.
There are several tools as well to perform this task, some of which are:
