Use steganography to hide files in plain sight

by Tris Hussey on January 25th, 2007

No, steganography isn’t a new dinosaur (I’d be talking about it on my science blog if it were), it’s a way of embedding a file within another file (encrypted, of course) to hide in in plain sight.

LifeHacker has a great article about it that points to easy tools to release your inner spy.

Unlike encryption, which obscures data in such a way that it’s obvious someone’s keeping something from listeners-in (and therefore heightens interest in that info), stego techniques offer no hint to the outsider that there’s any private data contained within the visible file. Like hiding your valuables from burglars in an empty cereal box in your kitchen cabinet, steganography keeps the existence of the secret item from everyone but those in the know.

I used Hide In Picture to unlock their secret file, so I had to try it here.

Yep there should be file in there.  Try it.  Hint … try pyw for a password.  And the icon?  Comes from my friend Chris Messina.
