TigerCube is an operating system that offers an all-in-one communications platform (including an advanced phone system and email), network security (with a firewall, content filtering, and virtual private networking), file sharing, and a fully integrated backup solution under a single, unified environment. TigerCube is free to use for up to 5 users.
Teractualizar is a daemon to synchronize files using SFTP as a secure transfer method. It also features the ability to upload and execute any application or command, which can be used to manage clusters of computers. It requires only baaic Unix commands, an SSH client, and the SFTP service. Currently, the client side of this system only runs on Windows NT (and derivative operating systems).
libextractor is a library used to extract meta-data from files of arbitrary type. It is designed to use helper-libraries to perform the actual extraction, and to be trivially extendable by linking against external extractors for additional file types. The goal is to provide developers of file-sharing networks, file managers, and WWW-indexing bots with a universal library to obtain meta-data about files. It includes a shell-command and bindings for Java (JNI) and Python.
P6P is a decentralized public virtual network designed for traversing NAT. It's useful mainly for peer-to-peer applications that don't implement NAT traversal themselves. It uses an unrouted segment of IPv6 (Unique-local), so it doesn't collide with other networks. It does not implement any additional security.
Crypt::IDA is a Perl module that implements Rabin's Information Dispersal Algorithm. This is what's known as a "threshold system": a secret is divided into n shares with the property that any k (the "quorum" or "threshold") of those shares (with k <= n) can be combined at a later time to reconstruct the secret. The algorithm should be cryptographically secure in the sense that if fewer shares than the quorum k are presented, no information about the secret is revealed. The module uses Math::FastGF2 to efficiently implement the algorithm, making it suitable for securely sharing and distributing even large files. The Crypt::IDA::ShareFile module implements a file format for creating, storing, and distributing shares created with Crypt::IDA.
Specially designed to secure paperless trading companies and organizations that put privacy and traceability in the heart of their problems of exchange, LinShare provides a simple, intuitive solution. It allows employees to upload files into their space. It can share files with internal or external collaborators. It offers several features to securely exchange files. It has integration with Outlook and ThunderBird, document preview, and directory integration.
Tranche is file storage and dissemination software. Designed and built with scientists and researchers in mind, Tranche can handle very large data sets, is secure and scalable, and all data sets are citable in scientific journals. Features include a fully decentralized architecture, support for very large files, very long-term file persistence/preservation, file immutability/integrity, provenance, encryption, licensing, versioning, and citability.
