BWTC32Key is a program I wrote that compresses data, then optionally encrypts it, and then outputs a Base32768 representation as the final output

A shell script which determines by brute force the best compression format (bzip2, gzip, Z, zip, etc.) and which compression level to use in order to archive a file the smallest possible.

A simple C++ library to code/decode data.

This program, based on the 7zip-full package on Debian systems, encrypts your files or folders along with their content names. It does this by entering a specified command and parameters into the 7zip tool using a Python script.

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 le format ZIP ou 7z, bien qu’efficaces, atteignent leurs limites en termes de taux de compression et d’efficacité pour les fichiers volumineux ou complexes. Ces outils sont souvent contraints par des compromis entre rapidité d’exécution et efficacité de stockage. Cette approche disruptive s’adresse notamment aux utilisateurs ayant besoin de manipuler des fichiers volumineux, comme les logiciels, les jeux vidéo ou les bases de données, où chaque octet économisé compte.

The RAZip bitstream format was designed to provide a faster random access to compressed data than what is currently possible using the GZIP format. During the desing phase, some other features were added, like encryption and error correction.

SFXCompress is an utility used to pack and/or encrypt a directory on a self-extracting file. It also includes the calculation of the MD5 function to check if the compressed file is correct. SFXCompress-gui is the graphical user interface written in Java of the Console utility sfxcompress. The Application comes also with the console version. MAC users, download "SFXCompress-bundle.dmg", double click and execute the script "InstallationScript" included into the dmg image. Linux Users: download "sfxcompress-bundle.tar.gz" or "sfxcompress-bundle.tar" and execute the script "install".

A plattform independent encryption-tool with a simple user interface (swing/java). It uses 'Password Based Encryption' (PBE) to encrypt and/or decrpyt files on the filesystem. Encryted files will also be compressed using the zip-format.

Simplebackup is a cross-platform backup program. It reads a configuration file then builds a compress backup set, finally places the compressed files into another location (a directory, a remote http,ftp,sftp server or even one or more email accounts).

Disaster recovery system based on strong file encryption and file sharing protocols. Similar to P2P applications but is used for storage of important files securely in case of data loss or disaster.
