thanks for this! but could you please explain how openssl encryption works a little more accurate? and also the downloads arent working anymore. thanks for your efforts.

links updated.
I unfortuantely don't have details how openssl encryption works.

alright thanks a lot! it's just i have no idea where to begin. do i have to enter these codes into cmd or is openssl a program? (i already installed it)
does anyone else know how this works?

oh, you want to know what you need to do.. right..
first read how to use PATH in windows: http://www.java.com/en/download/help/path.xml

then add 2 full paths there:
1) openssl installation directory (example c:\program files\openssl)
2) directory where lua.exe is installed (example: c:\data\lua)

now, open cmd as administrator and get to c:\program files (x86)\rovio\AngryBirds\data\levels\pack1\
you can now use the guide that I posted earlier.

thanks again. i managed to re encrypt a file. only thing which isnt working is describe i opened lua.exe (from your lua.zip) and wrote in exactly the code you postet at this step. always get the error code: stdin:1: '=' expected near 'Level1'

can you copy&paste exactly what you executed and what you got?

please learn how to use command line first.. (hint: command: cd)

i have done that ..
i have changed the directory to the F:\Rovio\Angry Birds\data\levels\pack1
