Open Source Linux Cryptography Software

Identityflow provides a framework for building protocol flows that perform distributed Identity operations. Examples of Identity Operations are Single Sign-On (SSO) and Attribute queries.

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.

This is a very powerfull criptography project that basicaly can be used to transmit or store secure data and study some cipher, hash and compression algorithms to understands how it works.

AESOP (Advanced Encrypted Stackable Open Proxy) is a powerful application for creating encrypted TCP tunnels.

This project will provide a library for using the AES round 3 cipher candidates (Mars, RC6, Rijndael, Serpent, and Twofish) in an easy to use API. Support for MD5, SHA.

Linux user-space implementation of Aladdin's eToken R2 device driver

This project has been migrated to GitHub : https://github.com/vlachenal/anch-framework AnCH framework aims to provide utility classes for some common programming features. Features are implemented to be used as simply as possible. This framework was initially a way to test new C++ specifications (C++11) and to test C++ design patterns and tricks. Only POSIX systems are supported for now. Others could be supported later. (Partial) Doxygen documentation can be found on project home page.

BruteNet is a system of the distributed brute force and distributed calculations built on user extensions capable to solve a great number of problems related to the partition on a lot of machines.With sample extention you can distribute brute md5-hash

Cryptographic Disk Driver for Linux

(Update: Project has been abandoned) KPuTTY is a KDE-based interface to run ssh based on the look of the popular free Windows SSH client PuTTY.

A hybrid dictionary/brute passphrase search tool for PMK discovery on 802.11 networks using WPA with preshared keys (PSKs)

The Password Auditing Project will be a compilation of other, previously released password auditing programs, in such a fashion as to reap the best benefits of each portion. Pulling innovations from John the Ripper, Lepton, Rainbow Tables, and more.

Peer Agent is a system that enable a group of users to carry out automated complex interaction via email services without relying on a trusted third party.

A fast and flexible implementation of SSH and SCP for Java, modelled on OpenSSH. In the beginning it should be simple, but hopefully eventually feature-rich.

Checking the integrity of a file on a remote and local untrusted or compromised server is to be achieved with minimal computational and storage requirements on part of a healthy verifier.

Quantitative information engineering systems.

Smartcard key storage daemon is an application for storing transparently keys for cryptographic applications on smartcards. (ie. GnuPG or OpenSSH)

Trent is a system designed to handle being a modular authentication server system for a wide variety of resource-managers, so that the manager can worry about resources, and not authentication.

UnityCA is a Certificate Authority "front end" based on the Community-Oriented CA (COCA) model, which was primarily developed for non-profit "free CAs." Organizational and end-user interfaces provide trusted web management of the installed CA (eg ElyCA).

tool collection to manage files and stuffs on a filesystem

distDES is a Java RMI-based application which manages load balancing on heterogeneous clusters. Development will extend the theoretical initial implementation to include clustered Rainbow Table generation and encryption algorithm collision detection.

Set of tools and libs for managing structured data in a very flexible way: Imp./Exp. ASCII, XML, SQL, PS, Tex/LaTex, RTF GUI: X-Windows, MS-Windows Interface to C++, DBs, Perl, PHP, Java, TCP/IP LISP-like interpreter written in C++ using C-LIB

Lecithine is a FUSE (file system in user space) using a secret sharing scheme. You can use Lecithine as regular file system. When writing to disk, data will be devided into randomly chosen pieces (secret shares) and stored into different places. Upon reading, the shares are merged together such that in turn the plaintext results. From a cryptographers point of view, there is no symmetric or private key ever needed to produce a ciphertext. This is how secret sharing schemes are designed.

"mASN1" - mini ASN.1 framework is a light ASN.1 framework written in C# for .NET framework. It can be used for creating classes that model ASN.1 types and are capable of encoding/decoding themselves to BER/DER codes. PER support is planned.

A low cost software and hardware KVM over IP and remote Console monitoring solution running on Linux. Secure administration and access to remote keyboard/video/mouse and serial console output. Easily configured and customised to suit user needs.
