    Encrypting Files via steghide

    So to make it really work for you, you need two things in general: the file that has to be hidden and the file in which the file will be hidden.If the file is not present in the current directory, then you need to put the full path to the file to encrypt the files.
    For example, suppose I want to hide this text file, hacking.txt, inside blogs.jpeg. I will use the following command:

    How to use Steghide?
    $ steghide embed -cf blogs.jpg -ef hacking.txt

    While the process goes on, it will ask for a passphrase, which will be used to embed the file. This passphrase will be used while extracting or decoding the file.We have successfully embedded a text file behind an image file!!!

    Extracting Information from non-informative object

    So now that you know how to successfully embed files behind files, let us understand how you can extract this juicy information.
    Retrieving the information is more easy than encrypting it; all you need is the passphrase and the command

    $ steghide extract –sf blogs.jpeg

    You will be prompted to write the passphrase that was used while encoding it. And now that you have the juicy text file inside your folder, you can write LS to check it.

    Retrieving Information

    This process can be done before extracting or embedding to get information about the image file to check how interesting it can be.
    Remember, if the image is password protected, you will need it!

    $ steghide info blogs.jpeg

    On giving the passphrase, we see the hacking.txt file being embedded.

    Compressing Files

    To save memory space, we use this option, but it is very important to understand that if you make a mistake, it will corrupt your entire file.

    Steghide has [9] level of compression. [1] being the lowest level = fast compression and [9] being the highest level = best compression
    We use -z switch to specify the level
    for example, to compress the image file to a certain level [9], we simply type

    $ steghide embed -ef hacking.txt -cf blogs.jpeg -z 9
