I understand the concept of Polymorphic and Metamorphic code but I recently read the Wikipedia page on both (for what ever reason I hadn't done this previously!). Now I really want to have a go at writing some metamorphic code for myself.
I am a master of no language, dabbler of many. I know some PHP, MySQL, c/c++, Java, Bash scripting, Visual Basic 6, VBScripting, Perl, JavaScript.
Can anyone provide an example of metamorphic code in any of these languages. I would like to see a working example, even where the output of the program is just "Hello World", to understand through example how this is happening (I am struggling to theorise how these techniques can be achieved through mental thought alone). Any language would do really, those are just preferred ones.
Additionally, searching the Internet has only returned a limited number of examples in c/c++ (not even complete working examples, more partial snippets of code), is that because the other languages I have suggested aren't low level enough to have the power/flexibility required to make metamorphic code?
