Open Source Cryptography Software

[IMPORTANT] Retroshare is now distributed on Github. Please go to http://retroshare.net to find the latest releases and sources. RetroShare is a cross-platform, secured and decentralized communication system. It lets you to securely chat, share photos, videos, and more with family and friends, using OpenPGP to authenticate peers and OpenSSL to encrypt all communication.

Calypso is a file sharing client using the anonymous network MUTE. Developped using C++ and Qt. For windows and linux, portable to other environments.

[[We are in the progress of moving to github]] Metalinks is a project to facilitate data distribution over mirrors and P2P networks. It does so by defining an XML format and the tools to handle these. The metalink files contain all the information needed to download and verify files.

WASTE is a mesh-based workgroup tool that allows for encrypted, private communication between distant parties on the internet, independant of local network organization.

A fork of WASTE 1.5.0.408 beta 3 starting form 1.5.1.412 beta 3

The Martus (TM) Bulletin System is used by human rights and social justice groups to track violations. This Java program is as easy to use as email. Bulletins can be encrypted or searched, and can be backed up to a remote server. See www.martus.org.

Backup P2P is a peer to peer application doing automated and secured backups inside a community (Jabber, XMPP). Each user shares some available space on his disk with others, to be able in return to remotely backup some of his own data.

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.

The J-WASTE project aims at the implementation of a platform independent client/server Java implementation of the WASTE protocol. This project started as a mandatory project course in networking at the Luleĺ University of Technology in Sweden.

A Secure, Firewall-Friendly Platform for Peer-to-Peer Networking. With a few mouse clicks, request remote access to colleagues' computer desktops, transfer files, sketch & chat, or videoconference. Automatic, authenticated & encrypted tunneling!

Simple and secure file transfers over SSL. Same program can be server and client. Runs as a unix daemon or Windows NT service.

An anonymizing peer-to-peer file storage network, similar to Freenet and Gnutella - only better, of course.

TCPFile is a friend to friend file sharing / instant messaging Java (1.6) program offering zipped and fully encrypted (RSA, AES) communication.

This ain't your daddy's crypto! We provide a set of C libs and utilities to perform cypherpunk style crypto functions, using your existing OpenPGP keys. Ring signatures; credentials; mental poker; timelines; zero knowledge proofs. Cool stuff!

A WASTE client. Download and create your own WASTE networks. For Windows XP 32/64, Vista 32/64, Win7 32/64, Win8 32/64, Win 10, Linux (WINE). *** NEW *** Distributed Autonomic-Performance-Tuning - A Goal-Seeking Swarming-Semiotic AI *** *** Built-in Self-Organising Anti-Spoofing Technology *** *** Medusa - Pure Ephemeral RNG - Routing, Security Extensions *** PLEASE ENSURE YOUR NETWORK USES THE SAME BUILD. FOR BEST RESULTS.

CrococryptQuerl =============== CrococryptQuerl (CQuerl) is a web-based open-source file encryption and file exchange tool. If you trust the application service provider which is running CrococryptQuerl, it can be seen as an "anonymous & encrypted safe deposit box for computer files". ---INTRO--- The encryption is done on-the-fly using the user's password. Of course, this requires a trusted TLS/SSL connection to the server running CQuerl. The user provides a file and password and receives an ID. No plaintext data is stored in CQuerl including filenames. If the user looses the ID or forgets the password, the encrypted file cannot be recovered - even by the service provider. DOWNLOAD ======== * A demo running on Google's App Engine (GAE) can be found here: https://crococrypt-querl.appspot.com ==> GAE limits the files to be uploaded to 1MB(!). ==> The file database will be cleared occasionally. ==> Crypto seems to be working slowly on GAE, so be patient! ;)

Cryptology is a Windows shell application that enables users to easily protect their files. It incorporates military grade encryption (256 AES) and secure shredding into a simple user interface

ECTP - Encrypted Compressed Transfer Protocol This protocol is similar to HTTP but with commands and features like FTP. The main features are security and compression abilities and the consequent use of one perisistant connection.

Free Tiger aims to provide a fast C implementation of the tiger and TTH hash algorithms in order to provide a performing hasher. It also aims to provide pure implementations of tiger and when possible TTH in other languages for reference.

GMX is a file-transfer application that permits the user to store files on a remote computer system: Google's GMail web-based email system. Development in C# (Microsoft VS.NET 2003).

Gloster is a secure and decentralized p2p program for small communities working under Linux and Windows

Modifications to Direct Connect protocol servers and clients to enable the usage of a more secure DC protocol, Hardened DC.

Herbivore is a distributed system providing information-theoretic perfect sender and receiver anonymity on the Internet.

ImpraStorage provided a private imap access to store large files. Each file stored on the server is split in severals random parts. Each part also contains random noise data (lenght depends on a crypt key) to ensure privacy and exclude easy merge without the corresponding key. An index of files stored is encrypt (with the symmetric-key algorithm Kirmah) and regularly updated. Once decrypt, it permit to perform search on the server and download each part. transfert process is transparent. Just vizualize locally the index of stored files and simply select files to download or upload. ImpraStorage automatically launch the parts to download, then merge parts in the appropriate way to rebuild the original file. Inversely, a file to upload is split (in several parts with addition of noise data), and ImpraStorage randomly upload each parts then update the index.
