steganography use it to hide a text file on a image

Now Iam going to teach you a very easy way to hide a text document inside an image file.
This process is called steganography. I already talked about it in this previous post LINK but I did not give any tutorial.
Iam making one now with step by step instructions and some visual help :)
The best part about this, is that you do not need any special software to do it! a simple comand line under Windows will do the trick.

Lets Start the Instructions:

For this tutorial I am going to hide a text file inside a jpg image.
1- Choose an image and a text document
1.2- Create a new folder on your hard drive, in my case I named my folder "a"
1.3- copy the text and the image file inside the folder, to make it easier in further steps you can rename the files with short names like 1 for the image and 2 for the text.

Ok step one is done, now you should have something on your computer similar to the image on the left.

 

 

 




2- Open a Command Prompt window. To do this go to the start menu and write cmd, then just click on the Command Prompt icon (I suggest you press CTRL+SHIFT and click the icon to run as an administrator)
If a new window with letters appeared then you are almost done! (Image on the right).

 

 

3- To proceed we need to locate and access the folder where we have our files. To navigate through the command prompt you need to use the cd command. Write cd\ and press the enter key.
3.1- Continue and write cd a (if a is the name of the folder you created on the first step)
3.2- You are inside the folder a. But just to make sure everything is in place write dir and press enter.
3.3- You are going to see the name of the image and the text document. If you renamed them as I said, you got 1.jpg and 2.txt
insert the following command: copy /b 1.jpg + 2.txt hiddentext.jpg
Press enter

 




4- And that's it, you are done for now. Just exit the command Prompt window and check your new file in the folder.

*Extra- To see the text you will need to right click the image file; select> Open with>Notepad>Browse to the end of the file and you will find your text.


What happened here was that you gave an order for the computer to copy the binary code of both files together.
The command line unlike Windows actually does what is told without any questions or hesitations. Now you know how to protect in plain sight your sensitive information. And you learned a great trick to impress your friends with your amazing computer skills :)
Hope it was easy to follow, and you learned something useful.
