Hide text behind images - Steganography Tutorial

Hello.

In this post, I will be talking about Steganography.
Steganography is the art and science of writing hidden messages in such a way that no one, apart from the sender and intended recipient, suspects the existence of the message, a form of security through obscurity.
The word steganography is of Greek origin and means "concealed writing" from the Greek words steganos (στεγανός) meaning "covered or protected", and graphei (γράφη) meaning "writing".

Let's start this tutorial.


Step 1:Copy an image file to c: of your computer.
Step 2: Copy the text(which you want to hide) to clipboard, by writing it in notepad and selecting it, right clicking it, then copy.
Step 3: Open cmd, by going to Start — All Programs — Accessories — Command Prompt.
Step 4: In cmd type :

cd \
echo “your text to hide” >> “image.jpg”.
Step 5 Now right click on image.jpg — Open with — Notepad. You can see your hidden text at the end of your image file contents.

NOTE: This is an example of basic Steganography. I will post advanced steganography in coming weeks.
Enjoy!!!
