STEGANOGRAPHY SOFTWARE

Welcome to the Steganography Software for JJTC.Com

Steganography applications conceal information in other, seemingly innocent media. Steganographic results may masquerade as other file for data types, be concealed within various media, or even hidden in network traffic or disk space. We are only limited by our imagination in the many ways information and data can be exploited to conceal additional information.

Over the years I've been asked to add steganography and related application to my website, in the tool matrix, or steganography list. For the most part my steganography pages have been a way to disseminate information about my research and interests.

The following provides a list of stegangraphy and related products. If URLs are provided to access the software, please provide the URL to the developers' sites rather than to binaries for download. As tools are added, let's try to keep them in alphabetical order. Websites come and go. Try to verify valid URLs prior to posting them as locations for more information.

NOTICE: Some of the programs listed here contain strong encryption components, and the export of them from the US is restricted by the EAR regulations. In order to avoid violating these restrictions, the application are NOT hosted on this site. Binaries are not linked from this page - please refrain from linking directly to binary files for download when adding new tools.
