Steganography for Windows and Linux

You can use steghide, which uses Steganography, to hide “important” pictures. Some might argue that there are better ways to hide things in linux and other might argue that it’s not really a practical way to hide 100s (even 1000s?) of pictures, but it’s just another weapon….
Basically steghide takes a jpg file and hides/embeds it in another file. It is important to note that the file size of the target file (the one that you will embed into) has to be bigger than the jpg file. However, the file type of the target file is important.
In the Linux version, you use this command to hide filea within fileb:
steghide embed -cf fileb.doc -ef filea.jpg
You can get some information about the embedded data by using this command
steghide ??"info fileb.doc
And to extract the embedded/encrypted/compressed data out to open for viewing pleasure,
steghide ??"extract -sf fileb.doc
