Many users wish to know how to obfuscate their code. There is no specific way to do so, but they all do the same thing. Here is an example of obfuscating some source and then printing it to the output window: | Many users wish to know how to obfuscate their code.

Say you want to decode the source of the obfuscated script. Some obfuscations are simple and allow you to just print the source. However, using the obfuscated source above as an example, this is why you simply cannot print the source: | Say you want to decode the source of the obfuscated script.
