Encrypt a text file in a JPG file

Here is a tutorial on how to hide files in Jpg’s. Please note it isn’t the most secure method, because the information is stored in plain text but it’s still cool to play with. A simple solution to make this more secure, is to use encryption on the RAR file when your create it, but thats not the point of this tutorial The idea is to show how files can be ’slammed’ together, to stop the average PC user from finding them.

Step by Step Instructions
You will need the following..

-Windows 2000 / XP (probably Vista, too!)
-Basic Knowledge of the Command Prompt

1. Gather your jpg file and the text files you wish to lodge into it. Here I have a black.txt which which I will slap inside my rider.jpg

2. Add both these files into a new RAR archive.Here the archive is black.rar

3. Open Command Prompt.

4. Go to the folder where your files are located, in this case ‘C:\hidden’

5. Type copy /b rider.jpg + black.rar blackrider.jpg where rider.jpg is the original picture, black.rar is the file to be hidden, and blackrider.jpg is the file which contains both.

6. Test the resulted JPG by opening it with winrar!

7. Enjoy the trick

8. Here is the image I created when making this tutorial! (Obviously rider.jpg and blackrider.jpg are the same image.)
