Put secret messages in your .jpg files

[Judland]

I recently posted on my blog about a tool that lets you encode any type of file inside of a normal .jpeg image file.

Only those who your share the passphrase with will be able to decode the hidden file within the otherwise normal looking .jpeg file.

Kind of cool.

Ummm...sounds a little dangerous to me...an easy way to encapsulate a trojan or virus...

Well, let's just say, if someone you don't know/trust sends you a .jpeg file and then tells you to decrypt it with a pass-phrase.... I'd assume something is up.

Otherwise, if you don't decrypt the .jpeg, I'd think the hidden file stays that way.

Who knows, if you've ever downloaded a .jpeg from the Internet, there's a chance you already have one with an encrypted file underneath.

In fact, a little more research on the topic sheds more light.

Download any MP3s over the Internet lately? MP3 steganography also exists.

More on the subject can be found here.
