What's obfuscation?

Obfuscation is to make the script look like gibberish, while still executing. The goal is to include as many lines as possible.

For example:

This code

Code:

@echo off
echo Hello World!
timeout 5 >NUL

is transformed into this

Code:

SET "_Data=World!5OFF>echonul@timeoutHello!"
%_Data:~18,1%%_Data:~11,4% %_Data:~7,3%
%_Data:~11,4% %_Data:~26,6% %_Data:~0,6%

Or this code

Code:

@echo off
echo ECHO is off.
pause

is transformed into this

Code:

@echo off
set ec=tr
set ho=yu
set llo=iu
set ld=yt
set pa=kl
for %%t in (use) do (
set %%t=bv
)
for %%a in (he) do (
set %%a=y
)
for %%b in (wor) do (
set %%u=lo
)
echo %y%%iu% %lo%%yt%
pause

Now, show me what you got!

So what does this obfuscate? Batch scripts? Sorry i don't know much of batch.

This just shows how someone can go about obfuscating their batch scripts. It provides a little insight on the subject.

It is not an obfuscator if that's what you were thinking.
