In the world of computer programming, there is always a desire to protect your code from theft and programmers use various tools to do that. One of these products is an obfuscator, a mini program designed to assist you with protection of your code. These programs are a part of software development and they create the so-called obfuscated code. Obfuscated code is a source or machine code that is difficult for humans to understand, and the creation of this code is called obfuscation. Therefore, obfuscation is a process of scrambling your source code so that it becomes unrecognizable for others to read.
Reasons to create an obfuscated code are various and depend from one programmer to another. The main reason is to protect the source code from copying or tampering with it by decompiling or just to prevent the reverse engineering. It is a principle called security through obscurity, which, self-explanatory, provides security of a design or implementation through secrecy. Another reason for using obfuscation is for recreational purposes, as a challenge to other programmers to try and solve the puzzle hidden in the obfuscated code. There are even contests created for the programmers where they can win a prize by writing or reading obfuscated codes.
The true purpose of obfuscation is to increase security and to reduce the file size. The size reduction of a file is a very important factor, as it enables programmers to make their programs easier to download because of the smaller size. There are obfuscating software products for every programming language out there. Now, some programs written in certain programming languages are harder to obfuscate and some are very easy.
Expert Tip for better obfuscating
I would advice you to insert at least one dummy function with dummy variables to confuse possible crackers.
All these methods used by these products have a slight chance to be reverse-engineered through memory tracing.
Inserting a few dummy functions and variables will confuse hackers a lot and level up your code security.

Best PHP Obfuscator – ionCube PHP Encoder
Concerning the PHP programming language, the best of the tested best proved to be the ionCube Encoder. There are a lot of features that set apart this obfuscating software from the others in the PHP obfuscating software market. In the follow-up we will present to you the features of this awesome piece of software tool so that you can confirm our claims yourself. Although this software tool is basically an encoder but it has the obfuscator abilities too. What it essentially does is that it encodes the PHP scripts for added protection and better performance, with the compiled bytecode.
ionCube Encoder supports encoding for all versions of PHP from version 4 up to 5.4 version. In the Pro and Cerebrus versions of this software tool you can have the ability to generate license files, which in turn restrict access to your encoded files. This means that you can limit by time and by machine the code for your PHP software. The ionCube PHP Encoder obfuscates bytecodes after the compilation, therefore adding stronger security to your source code. You can select whether you want the ASCII or Binary file format, which is a nice addition. You can basically achieve whatever your heart desires with this software aiding tool, as it can also add customized messages for file expirations or unauthorized access. The ionCube Encoder is the ultimate tool for your PHP encoding and compiling, and on top of that it also presents the best PHP obfuscator on the market. The obfuscation process is really easy to use and it is thorough, also decreasing the size of your PHP software.

Best Java Obfuscator – Zelix KlassMaster
This second generation Java obfuscator by Zelix is the best out there when it comes to this programming language. It uses the bytecode obfuscation so that it can prevent your Java creations from reverse-engineering and also reduce the file sizes. KlassMaster was first released in 1997, and since then the developers have constantly upgraded this tool, so that it can provide the best possible performance when it comes to Java programming obfuscation. Besides the first generation Name Obfuscation ability, which changes meaningful class, field and method names to meaningless strings, KlassMaster also comes with features such as Flow Obfuscation, Exception Obfuscation and String Encryption. Flow Obfuscation makes slight changes within the bytecode that hide the control flow and not changing the code runtime while doing it.
The feature of Exception Obfuscation presents the additional change to the bytecode which complicates it even further and renders the decompiler almost useless. While decompiling Java software, competitors or hackers will check for targets such as string laterals. With String Encryption, their task will be difficult, because the KlassMaster will encrypt your string laterals and store it in a different location. It will also add fragments of code to your classes so that the strings could be decrypted at run-time. Except all that, It’s worth mentioning the great compression ratios and the easy to use GUI interface. Compression is better than in most tools on the market and in turn enables you to get faster loading times. Graphical user interface is really simple and your files are protected, what makes the KlassMaster is a pretty powerful tool. When considering these amazing features, plus the great price, the KlassMaster by Zelix definitely is the cream of crop Java programming language obfuscating software tool.
