Question

I have been using Steghide for hiding data inside images. I recently found that the metadata of the cover file is removed during this process. Also there is no active development for this software since 2003. Although I haven't found any alternatives online / not enough feedback.

I am interested in hiding text and images inside other images. Anyone has experience using such software? Ideally it would be a mature solution which is still supported, compatible with Java or Windows + Linux command line.

This tool will be used by a java library

Explanation / Answer

OpenStego is one that springs to mind on Linux - it also has a Windows client, and a Java executable (so will presumably work with Mac too).

It's still in active development, with the latest version having been released in April this year (2014).

Update:

It's in the reops (at least for Fedora and Ubuntu): sudo yum install OpenStego or sudo aptitude install openstego
