Do you know some good (better if FOSS and cross-platform) steganography software that runs on GNU/Linux?

The features I'm searching are:

  • steganography software (better if FOSS and cross-platform)
  • it must run on GNU/Linux
  • must hide data inside audio/video/image files
  • support of additional cryptography

I already use a cryptographic software, but I want to use a steganographic one as an addition to it.

Any suggestions will be appreciated, thanks a lot in advance!

I don't know of a one-size-fits-all application that can perform these operations on audio,video, and image files, but the StegoArchive website contains a massive archive of steganography software, if you don't mind using multiple tools for the job. You can even order a CD containing the software on the website!

For cross-platform, check out their Java section. For GNU/Linux, check out their Unix/FreeBSD/Linux section.

A lot of it is freeware, and open source, so you probably won't need to put any money down to get this job done.

here's a quite intriguing project:

Hydan can embed messages into an executable without altering its size.

Hydan steganographically conceals a message into an application. It exploits redundancy in the i386 instruction set by defining sets of functionally equivalent instructions.

It then encodes information in machine code by using the appropriate instructions from each set.

Features:

  • Application filesize remains unchanged
  • Message is blowfish encrypted with a user-supplied passphrase before being embedded
  • Encoding rate: 1/110

Hydan is crossplatform (BSD/Linux/Windows) FOSS.

I'm the author of Steg, a portable cross-platform software for steganography, written in C++, available here:

For now there is support for images only (jpg and uncompressed). The other requirements you are searching for are all meet. Is not FOSS but really, does not contain any surprise if not some nice parameter you can tune for your steganography intent. ;-)
