Hiding information steganographically

Posted by bene - 04/12/08 at 12:12:59 am

I just found this nice Unix tool to hide sensible data in your multimedia files like JPEG images: steghide

It attaches the secret in compressed+encrypted form and even adds a checksum

The usage is quite simple:

# steghide embed -cf hidden.jpg -ef secret.txt
# steghide extract -sf hidden.jpg
