You can hide text files in an image by embedding the text file into it. This method is called steganography.









There are many tools for image steganography. These tools help us to hide our message inside an image so that others can't read it directly.





Now let's do some steganography using a simple tool.





Steps





Download the tool (zip file). (zip file).

Extract the zip file.

Open the application S-Tools .

Drag the image zebras from the downloaded folder into the application.

Create a text file somewhere with the secret message ( message.txt ).

Drag the text file into the image in the application.

Enter the Passphrase (anything you can remember, here I am giving "abc").

Reenter the Passphrase inside Verify passphrase ("abc").

Click OK

Wait for a new image to appear inside the application named hidden data.

Right-click on the image and select Save As.

Choose your location and enter file name with extension ".bmp" ( for eg: hidden.bmp).





Now the image is saved with the text file hidden inside it. You can send the image to anyone.





Now let us see how to reveal the secret message.





Steps to reveal the hidden message





Open the application S-Tools.

Drag the image with the secret message embedded to it into the application

Right-click on the image and select Reveal.

Enter the Passphrase you entered earlier ("abc").

Verify the passphrase by reentering ("abc").

Click OK.

A dialog box will appear with the text file name ( message.txt ).

Right-click on the text file name and click Save As and save the text file with the extension ".txt" (hidden.txt).

Now you can see the hidden message in that text file.
