This program aims at providing a java solution to hide secret information(such as secret file) to JPEG images. Hiding algorithm contains Jsteg and F5. The main(probably the toughest) stuff is encoding and decoding JFIF files.
mp3stegz is an application that apply steganographic (steganography) algorithm in mp3 files. mp3stegz will maintain original mp3 file's size and sound quality. The hidden message is compressed(zlib) and encrypted(Rijndael).
This application aims to be a simple, small and portable enrypter which encrypts any number of files of any size quickly but securely. It also preserves file extensions which are encrypted with the file and handles ANY file type.
This is an ASP.NET C# implementation of a CAPTCHA. You can choose any; size, font, color, background, pattern, add random lines or even add a background image. Also includes an audible version of the captcha text as well as refresh functionality.
A tool to hide a file into a image with no affects the size. It uses a steganography techinique that change the least significant bit in the RGB color systems of non compressed images to store the bits of the file to hide.
fswatch is a small, simple utility that detects changes in a filesystem. it watches for a file system integrity. it checks inode, links, uid, gid, mode, size, flags, ctime, checksum (SHA1).
Secure Key is an uncrackable security mechanism that minimizes trust given to stored keys, and obfuscates key data in random noise. The Secure Key itself is a hardware device that plugs into your PC (and the server the other end). The key is sent to user

...It will allow you to write and read hidden messages within mp3 files without creating any audible differences to the mp3. The messages could be a text file, jpg or any other file depending on the mp3's size.
Lrzip is a lossless compression application designed to scale with modern hardware resources using a variety of different back end compression algorithms with the ability to have unlimited size compression windows and optional high grade encryption. The larger the file the better the compression possible and the more powerful the hardware the faster it can compress with a heavily multithreaded design.
