Hiding programs in pixels


Recommended Posts

Computer and Console seemed only to have to do with games , same for developer corner. So I think this would be the better forum because the program(s) i share is not a game, but can certaintly take apps and put them into pixels.





I wrote a program. That converts a program's bytes. Into pixel values. I wrote a program. That is also the same program that deconverts program's bytes... into a program.


An image can store a program.

0 - 255 easily done in a single pixel.


1024x1024 image can hold ~1MB of data.


We store our programs in pixels. But we can also use any range of 255. Masking ourselves from those antivirus mad men. To hide our programs or not to !


Now this has been shared. I share the source. I took a big risk sharing something without googling if others have done it. i like to believe i am special.

?I compile the program for you. With optin to deconvert on, press a key it will create the gw.setup.exe.


?ImageTest.exe. (I press l in window one opened, any key would probably do)

?I use multibyte character set . no angry please.


The Deconverter (pixels/image to app)



?The program

?The image for guild wars setup

?a tex t file dtailing how large the exeuctable for guild wars is suppose to be.

The converter (app to image/pixels)



The program

test.exe (gw setup)
