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.
