Obfuscation is code or instructions that are purposely complicated to help conceal what the code performs. A programmer may do this to help prevent the program from being modified, stolen, or prevent a program from reading the code and understanding its true, malicious, intentions. For example, obfuscation is used with URLs to conceal the real address a user is directed to when clicking on a link from an e-mail message or web page. In some instances, obfuscated code is used in contests as brain teasers.
@echo off setlocal %1 %0 :: A B C D E F G H I J K L M N O P Q R S T U V W X Y Z set A=%5&set B=%6&set C=%8&set D=%3 for %%? in (1 2 3 4 5 6 7 8 9) do shift set A=%C%%7%A%&set C=%D%%4%B%&set D=%7 for %%? in (1 2 3 4 5 6 7 8 9) do shift echo %A% %C%%2%2 %8%D%%4!
The above code is difficult to understand without taking the time to break down the code and is a lot more difficult than "echo GOD BLESS YOU."
