    Hiro's helpful tips: Steganography

    Steganography is the science of hiding information. It can be used in many ways, and for many purposes. I'm going to show you one tonight and give you some resources if you are interested in learning more on the subject.
    Tonight I'll show you how to hide a text file in a graphic. I use this for hiding all of my passwords, but you could use this for anything you wanted to hide.
    Here's a picture of an apple:


    Here's the same picture with a text file stegged in it:


    Can't tell the difference, can you?

    A real simple steganography program is Steghide - Steghide Link
    Download Steghide, install it and download the second apple photo (apple.jpg).
    To extract the hidden file do:
    Code:
    $ steghide extract -sf apple.jpg
      Enter passphrase: gamahiro
      wrote extracted data to "secret.txt".
    Open secret.txt to see the contents.

    To steg a file into a graphic do:
    Code:
    $ steghide embed -cf AnyPicture.jpg -ef SomeSecretFile.txt
      Enter passphrase:
      Re-Enter passphrase:
      embedding "SomeSecretFile.txt" in "AnyPicture.jpg"... done
    Easy. Now go hide everything from your parents

    Here are some links for other steganography software and resources:

    Feel free to ask if you need help with any of this.
    Hope this helps.
