Steghide is designed to be portable and configurable and features hiding data in bmp, wav and au files, blowfish encryption, MD5 hashing of passphrases to blowfish keys, and pseudo-random distribution of hidden bits in the container data. Steghide is steganography program which hides bits of a data file in some of the least significant bits of another file in such a way that the existence of the data file is not visible and cannot be proven. Voices is a *nix program that hides files in mp3's. tags | encryption, tcp, steganography SHA-256 | ebef4d7fb76c4d35e30fe24a2260a12237b058adad112fa1c746f7a0277b289c Download | Favorite | View Posted Authored by Conundrum | Site It provides covert channels in the sequence numbers and IPIDs of TCP connections. In this way, detection of odd-looking sessions is avoided. It can hide the data underneath real TCP connections, using real, unmodified clients and servers to provide the TCP conversation. It was designed to be undetectable, even by people familiar with the tool. Stegtunnel is a tool written to hide data within TCP/IP header fields. Changes: Added a reliable file transfer mode using Hamming-style error correction, and removes the requirement for a proxy IP address on some operating systems. tags | encryption, steganography systems | linux, freebsd SHA-256 | 0956fa7b69fc405cc4c00ff224e5435d4165a1298ffd1ba107c7cb07d1891573 Download | Favorite | View stegtunnel-0.4.tar.gz Posted Authored by Todd MacDermid | Site Separate logical channels are used to carry a highly redundant watermark to ensure it is extremely difficult to remove this information by accident, simple reformatting, etc. Similar to steganography, watermarking adds invisible information to the document which allows you to track which copy of the document leaked, for example. Snowdrop adds invisible watermarks to text or source code documents. tags | perl, encryption, steganography systems | linux, windows SHA-256 | 85dc1dae9ef62a01b8b40ec00541ef8e2c3f4fd8b57df8fb915e8f9b41c3513f Download | Favorite | View Posted Authored by Michal Zalewski | Site Works on Linux and Win32 with perl installed. is a perl program which hides data in bmp images without modifying their size. Anybody can send a steganographic message, but only the private key owner will be able read it. Like cryptography, it uses a pair of keys: the public one can be shared, whereas the private one must be kept secret. Publimark is a command line tool to secretly embed text in an audio file. tags | encryption, steganography SHA-256 | bc96c067bb5ce51d3d1b4245d54bc954f8ae25907bae0fd4b9273bd2717ac1e3 Download | Favorite | View Publimark Steganographic Tool 0.1 Posted Authored by Gaetan Le Guelvouit | Site Publimark Steganographic Tool 0.1.1 Posted Authored by Gaetan Le Guelvouit | Site
