A Quick Steganography Tutorial

Thursday, October 06, 2005

OK, let's get into a quick tutorial on steganography. Going by the wiki definition, steganography is 'the art and science of writing hidden messages in such a way that no one apart from the intended recipient knows of the existence of the message'. I have tried many of the programs out there but today we will be going over a shareware app called Masker.

So go and download it and run it. Here, the program is asking for a 'carrier file' which essentially is the host file that is going to hide whatever you are planning to hide (make note that I will be choosing a .GIF file).


Find your picture and fill in a password.


Now find a file you want to embed in your .GIF file.


Here I am choosing a text file named 'secret.'


When you finish embedding the file, the .GIF file should now be larger(as you are hiding data in it). I was having problems with blogger so I am unable to show you the end result but if you check the size of the original file versus the size of the file with the embedded data, your latter picture should be larger.
