Le logiciel NTK Ultra-Compression répond à une problématique essentielle de l’ère numérique : comment réduire la taille des données à leur minimum absolu sans compromis sur leur intégrité, tout en s’affranchissant des contraintes temporelles ? Dans un monde où les volumes de données explosent et où les solutions actuelles de compression restent limitées par des compromis entre rapidité, efficacité et complexité, nous proposons une approche disruptive. Les solutions actuelles, telles que...

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

Moved to GitHub.com/gdraheim/zziplib/ The ZZIPlib provides read access on ZIP-archives. The library uses only the patent-free compression-algorithms supported by Zlib. It provides functions that transparently access files being either real files or zipped files, both with the same filepath

MicroZip is a powerful file compression and encryption utility for mobile phones which allows you to create and extract compressed archives in multiple formats and encrypt sensitive information with powerful AES-256 encryption. MicroZip can create and extract ZIP,TAR,TGZ,TBZ2 archives and extract many other formats as JAR,GZ,BZ2,TBZ,WAR,BZIP2,GZIP,Z,TAZ,CBZ etc. MicroZip allows you to extract selected files without extracting the whole ZIP archive. MicroZip also supports encrypted ZIP...

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.

CADI is an implementation of the JPIP standard (JPEG2000 Interactive Protocol - Part 9). CADI includes a JPIP server, a JPIP proxy, and a JPIP Client. CADI is designed and programmed with the aim to provide a flexible framework to test and develop ne

Alternative approach to minimum redundancy coding (fixed-length) without using tree data structures. The main advantages are simplicity and flexibility.

JPar2 is a 100% pure java (1.5+) implementation of the PAR2 specification.

Destral is an open source, multiplatform implementation of the Hacha 3.0, Hacha 3.5 and HJSplit split and join algorithms. These utilities are widely used in forums and news to distribute one large file as many smaller files. A Qt GUI is also planned

SMSCompress is a project of investigation, development and implementation of different SMS compression techniques. Using these techniques, SMS of more than 160 characters can be sent at only one SMS, saving money to the user ;)

Basic Compression Library is a portable library of well known compression algorithms, such as Huffman coding, written in standard ANSI C. It is intended to serve as a set of building blocks for specialized compression algorithms.

PileWorks provides the organizational structure for coordinating several different projects which approach some aspect of Pile Technology. PileWorks defines a set of interfaces and implements some basic infrastructure for Pile engines and agents.

The OS561 operating system based around FORTH/Java. The OS is to run on a VHDL chip OpenHardware design called the Minon, but could become available for other platforms. The unique point of the design is a revolutionary data compression technology.

Numerically estimate an efficiency of code construction algorithms. Randomly generate n binary words of length m with minimum Hamming distance d and create a prefix code (= retrieval tree) from them. Based on PhD work.

ReHash is an easy-to-use console-based hash calculation tool written in C++. It supports many algorithms and output formats and it can be fully configured using some of the many command-line arguments which can be passed to the tool.

jPasswordWallet strores your passwords in security. Find, modify or create quickly a password in the database. Organize your passwords as you like with creating categories and sub categories.

LZO is a compression library which is widely used around the world. The main problem with LZO is that it is absolutely not human readable. People have done crazy stuff to get LZO to run in their language. 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...
