Using Metalink's chunk checksums, aria2 automatically validates chunks of data while downloading a file like BitTorrent.
Galet is a peer-to-peer application which primarily aims to provide easy-to-setup, secure communication channels between the computers of people who know and trust each other. Its secondary goal is to create a public network based on these channels. No direct connections occur between two nodes that have not been explicitly accepted by the users of these nodes. This makes the network very difficult to censor, as an attacker's direct access to the network is limited.
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.
