How to hide secret messages inside an image file using CMD

Creating Secret Messages (Steganography)

Steganography is basically the practice of concealing messages or information within other non-secret text or data.

In simple terms, steganography means hiding of any text inside image files, video etc.

For this, we need-

1. Windows OS
2. An image file(.png format)
3. A text file(containing data you wanna hide)

Here are the steps to hide text in image using command prompt-

• Make a folder containing the image file(.png format) and the text file containing the text we want to hide.

• Open command prompt.
• Type cd/

• Now using 'cd' command, navigate to the place where your folder is present.

• Type copy /b "image_file-name.png" + "text_file_name.txt" = "combined_file_name.png"

• Press enter.
• Now, go to the folder. You will see an image file(.png) with the name you entered in place of  combined_file_name.

• Now, open that image file using notepad.

• Scroll down till the end of the file and you'll see your text.

• Your text is hidden :)
