In software development, obfuscation is the deliberate act of creating source or machine code that is difficult for humans to understand. Like obfuscation in natural language, it may use needlessly roundabout expressions to compose statements. Programmers may deliberately obfuscate code to conceal its purpose security through obscurity or its logic or implicit values embedded in it, primarily, in order to prevent tampering, deter reverse engineering, or even as a puzzle or recreational challenge for someone reading the source code. This can be done manually or by using an automated tool, the latter being the preferred technique in industry. OvervieweditThe architecture and characteristics of some languages may make them easier to obfuscate than others. 12C,3C,45 and the Perlprogramming language6 are some examples of languages easy to obfuscate. Recreational obfuscationeditWriting and reading obfuscated source code can be a brain teaser. A number of programming contests reward the most creatively obfuscated code, such as the International Obfuscated C Code Contest and the Obfuscated Perl Contest. Types of obfuscations include simple keyword substitution, use or non use of whitespace to create artistic effects, and self generating or heavily compressed programs. According to Nick Montfort, techniques may include naming obfuscation, which includes naming variables in a meaningless or deceptive way datacodecomment confusion, which includes making some actual code look like comments or confusing syntax with data double coding, which can be displaying code in poetry form or interesting shapes. Short obfuscated Perl programs may be used in signatures of Perl programmers. These are JAPHs Just another Perl hacker. 8ExampleseditThis is a winning entry from the International Obfuscated C Code Contest written by Ian Phillipps in 1.

Some Python examples can be found in the official Python programming FAQ and elsewhere. 1. Advantages of obfuscationeditThere are several advantages of automated code obfuscation that have made it popular and widely useful across many platforms. On some platforms such as Java. ,1. Android,1. 8 and. NET a decompiler can reverse engineer source code from an executable or library. A main advantage of automated code obfuscation is that it helps protect the trade secrets intellectual property contained within software by making reverse engineering a program difficult and economically unfeasible. Other advantages might include helping to protect licensing mechanisms and unauthorized access, and shrinking the size of the executable. Decompilation is sometimes called a man at the end attack, based on the traditional cryptographic attack known as man in the middle. Disadvantages of obfuscationeditWhile obfuscation can make reading, writing, and reverse engineering a program difficult and time consuming, it will not necessarily make it impossible. 1. Some anti virus software, such as AVGcitation needed, will also alert their users when they land on a site with code that is manually obfuscated, as one of the purposes of obfuscation can be to hide malicious code. However, some developers may employ code obfuscation for the purpose of reducing file size or increasing security.
