Some Python examples can be found in the official Python programming FAQ and elsewhere. This slowly displays the text "Just another Perl / Unix hacker", multiple characters at a time, with delays. * LEAST LIKELY TO COMPILE SUCCESSFULLY: Ian Phillipps, Cambridge Consultants Ltd., Cambridge, England */ #include main ( t, _, a ) char * a %p $_ = $d sleep rand ( 2 ) if /\S/ print This is a winning entry from the International Obfuscated C Code Contest written by Ian Phillipps in 1988 and subsequently reverse engineered by Thomas Ball. These are JAPHs (" Just another Perl hacker"). Short obfuscated Perl programs may be used in signatures of Perl programmers. double coding, which can be displaying code in poetry form or interesting shapes.data/code/comment confusion, which includes making some actual code look like comments or confusing syntax with data.naming obfuscation, which includes naming variables in a meaningless or deceptive way.Types of obfuscations include simple keyword substitution, use or non-use of whitespace to create artistic effects, and self-generating or heavily compressed programs.Īccording to Nick Montfort, techniques may include: A number of programming contests reward the most creatively obfuscated code, such as the International Obfuscated C Code Contest and the Obfuscated Perl Contest. Writing and reading obfuscated source code can be a brain teaser. The properties that make a language obfuscatable are not immediately obvious. Haskell (programming language) is also quite obfuscatable despite being quite different in structure. C, C++, and the Perl programming language are some examples of languages easy to obfuscate. The architecture and characteristics of some languages may make them easier to obfuscate than others.
