Storing Files in a .JPG Image with Windows
22 11 2007The following is a basic steganography tutorial on how to archive files in another file with the JPEG extension. If you’re really doing this for secrecy you could also make sure to put all the hidden files in a RAR archive an put a password on that before inserting it into the image.
The Tools
- Windows 2000, XP, Vista, etc.
- WinRar (Optional)
The Process
- Get your image file and other file to hide in one folder. Example: hidden.txt which will go into secret.jpg.
- If you want to hide more than one file in the image you need to RAR all of those files. Example: hidden1.txt and hidden2.txt get archived into hidden.rar which will go into secret.jpg.
- Open Command Prompt and navigate to the folder where all the files are located. Example: “C:\secret” contains the hidden.rar and secret.jpg files.
- Go to the folder where your files are located, in this case ‘C:\hidden’
- Enter ‘
copy /b <original image name>.jpg + <complete filename of file to hide> <output image name>.jpg‘ to have the file to hide be hidden in the output image which looks the same as the original image. - You can now test the outcome by attempting to open <output image name>.jpg with WinRAR.
