HashSum is a .NET port from GNU's md5sum and sha1sum. It supports: hash algorithm selection between MD5 and SHA1 (more could be added later) and compatibility between HashSum and GNU's checksum file format

Genetic Algorithm File Fitter, GAFFitter for short, is a tool based on a genetic algorithm (GA) that tries to fit a collection of items, such as files/directories, into as few as possible volumes of a specific size (e.g. CDs or DVDs).

NO LONGER MAINTAINED, NO LONGER SUPPORTED Manifest Maker is a graphical Python application which takes a file or group of files and creates a plain text manifest list of each item. The manifest includes the file name (including directory structure) as well as a checksum of the file.

...MicroZip allows you to extract selected files without extracting the whole ZIP archive. MicroZip also supports encrypted ZIP archives with both classic ZIP encryption and AES 256 encryption algorithm.

This software zips and unzips a .txt file, using the Huffman encoding algorithm and the list and tree data structures. The result files are named zippedFile.txt and unzippedFile.txt and can be found at the same directory as the Text Zip executable file.

...SafePassDB is a free multi-platform software application written in Java programming language that will enable you to protect all of your personal data with one "Master Password" using AES (Advanced Encryption Standard). SafePassDB is light weight and super easy to use! Current version of the software uses 128 bit AES (Advanced Encryption Standard) algorithm, which is a standard by U.S. National Institute of Standards and Technology (NIST), for protecting your personal data. IMPORTANT: In order to run SafePassDB you need to have Java installed on your computer. Java is free and can be downloaded from - http://www.java.com/

Use of Michael Rabin's Information Dispersal Algorithm to provide secure, dispersed storage in a networked environment. For full download, please get both Math-FastGF2 and Crypt-IDA releases under the files link. See project wiki for more information.

Duplicate Files Finder is a cross-platform application for finding and removing duplicate files by deleting, creating hardlinks or creating symbolic links. A special algorithm minimizes the amount of data read from disk, so the program is very fast.

The utility sfxcompress is a bash script used to pack and encrypt the current directory on a self-extracting file. It also includes the calculation of the MD5 function to check if the compressed file is correct.

...This is basically a reimplementation of dupfinder as: it doesn't compile on my computer, the executable won't work either, the projects seems dead and I didn't wanna work through the original code. So Look'n'Feel should be somewhat the same, though some changes have been made. Algorithm is simple and suitable for large file sets with few differences: basic set of duplicate candidates is determined by file size, then candidates are compared byte-wise. So for files which don't start to differ by growing at the tail it reduces read operations greatly compared to hash-based comparision (i.e. test case: 40GB of files, 16GB RAM, many differences: initial compare (uncached by OS) around 300sec, subsequent compare (relevant file parts cached by OS) ca. 2sec) Note: this program is not related to lsdup

An on-line backup system for UNIX. Backups are encrypted, and changed files uploaded using a rsync-like algorithm. See Project Home Page for full description.

Implementation of LZW compression/decompression algorithm in Java.

ShredBitz is a free and simple file shredder tool that can wipe selected files from any hard disk drive. ShredBitz is written in the java programming language and uses a custom written algorithm for shredding. ShredBitz is a very powerful tool.

DWIP is short for Disk Wiping and Imaging Tool. This tool is being built for Mississippi State Universities National Forensics Training Center for use on a live cd to give out to it's students.

PZip is a C++ library and application with similar syntax and usage to bzip2 and gzip. The underlying compression algorithm is PPMD and compression performance is significantly better than either gzip or bzip, with similar speed.

Calculates differences of executable files using a randomized algorithm for matching with mismatches.

czip is a unix based utility written for the cell broadband engine. It allows its users to compress files in gzip format. It uses Jean-loup Gailly's deflate algorithm and is based in part on pigz, Mark Adlers parallel version of zlib.

Package for coding and decoding files with Matheos algorithm from commandline or console in Linux/Unix Environment. Based on Keys stored in files or as hardware locks (on devices). Fast and strong coding. Fast encoding.ONLY BINARY PACKAGES FOR NOW!

A compression engine based on the Huffman trie algorithm. The algorithm is pretty cpu-light, and as such, runs much more quickly than RAR or other 'heavy' algorithms, but could still achieve decent compression. Use with tar for multi-file archives.

Simplify is aimed to raise images compressibility by using a reversible blurring algorithm.

A Compression Utility - based on own bit algorithm

Jarsync is a Java implementation of the rsync algorithm, a delta compression algorithm for fast network file transfers.

This is an academic project. A library and a sample program will be developed, that will implement the Burrows-Wheeler compression algorithm, using C++ and templates. This is the same algorithm for BZip.

...Usually it implies inline assembly or trying to execute data which actually contains machine code. This is sick. Whoever is responsible for this sorry situation ought to be ashamed. So I'm going to deobfuscate LZO and provide a ISC implementation of this algorithm in Python and C. In addition, I will provide a textual description of the algorithm so that it can be easily ported to any programming language. I expect a severe performance degradation, but I leave optimizing for speed to other people.
