Steghide - Hide information Inside Image and Sound Objects






Steghide is a steganography program that allows you to hide confidential files inside an image or audio file with a passphrase. Supports BMP and JPEG image formats, AU and WAV audio formats. By default it uses Rijndael algorithm to encrypt the file and the key size is 128 bits. If you want to use any-other supported algorithm to encrypt files, use steghide --encinfo command to bring the list. Steghide - Hide information Inside Image and Sound Objects


Steghide Features:


Compression of embedded data.
Encryption of embedded data.
Embedding of a checksum to verify the integrity of the extraced data.
Support for JPEG, BMP, WAV and AU files.


Install in Debian System


sudo apt-get install steghide

Install in Termux


pkg install steghide


To use this tool, type “steghide” in your terminal.






The receiver also has to use same steghide tool to recover the data, so if the password is correct, the contents of original file will be extracted from the image file and saved in the current directory.

You can also view the info related to embedded data by typing this below command.



Command: steghide info kumar.jpeg








How to hide a file inside image ?



Steghide doesn’t have the GUI, so run the following command on terminal to embed the file inside the image. In the following example, we are going to hide atul.txt text file into kumar.jpeg image.


Command: steghide embed -cf kumar.jpeg -ef atul.txt






Above command will embed the file taskwarrior in the cover file kumar.jpeg



How to Unhide/Extract a file ?


Run the following command in terminal and provide the correct passphrase to Unhide/Extract a atul.txt file from the stego file Linux_logo.jpg, which will automatically save in the current directory.


Command: steghide extract -sf kumar.jpeg








steghide –encinfo


Displays the list of supported encryption algorithms and modes that can be used.steghide –encinfo


Displays the list of supported encryption algorithms and modes that can be used.



steghide -encinfo ( Termux )
steghide --encinfo ( Linux )







How to hide a file inside audio file ?



Use the same format and change the stego file type to audio instead of image file. See the following example.


Command: steghide embed -cf atul.wav -ef secret.odt








Above command will embed the file secret.odt in the cover file test.wav


How to Unhide/Extract the file ?


Run the following command in terminal and provide the correct passphrase to Unhide/Extract a secret.odt file from the stego file test.wav, which will automatically save in the current directory.



Command: steghide extract -sf atul.wav
