distributed.net is a loosely knit group of computer users from all of the world that is taking up challenges requiring lots of computing power (most notably the RC5, DES, and OGR cracking contests). It is simple to participate in the challenges by downloading and running their client software (which uses idle CPU time to complete its tasks).
The modular syslog allows for an easy implementation of input and output modules. The modules that mantain compatibility with its precursor are included in the standard distribution along with four modules: om_peo (an implementation of PEO-1 and L-PEO, two algorithmic protocols for integrity checking), om_mysql and om_pgsql (modules that sends output to a mysql and postgresql database, respectively) and om_regex (a module that allows output redirection using regular expressions).
TEA Total is a collection of extremely small encryption tools. At the heart of TEA Total is the TEA (Tiny Encryption Algorithm): a fast and secure 128-bit private key algorithm which was developed and placed in the public domain by David Wheeler and Roger Needham of the Cambridge Computer Laboratory.
vpnd is a daemon which connects two networks on network level either via TCP/IP or a (virtual) leased line attached to a serial interface. All data transfered between the two networks are encrypted using the unpatented free Blowfish encryption algorithm with a key length of up to 576 bits (may be downgraded to a minimum of 0 bits to suit any legal restrictions).
OpenVPN is a robust and highly configurable VPN (Virtual Private Network) daemon which can be used to securely link two or more private networks using an encrypted tunnel over the Internet. OpenVPN's principal strengths include wide cross-platform portability, excellent stability, support for dynamic IP addresses and NAT, adaptive link compression, single TCP/UDP port usage, a modular design that offloads most crypto tasks to the OpenSSL library, and relatively easy installation that in most cases doesn't require a special kernel module.
yaSSL is a C++ based SSL library for embedded and RTOS environments, designed for individuals who prefer to use the C++ language. For a C-based solution, please see CyaSSL. yaSSL supports the industry standards up to TLS 1.2, and also includes an OpenSSL compatibility interface.
Stegdetect is an automated tool for detecting steganographic content in images. It is capable of detecting several different steganographic methods to embed hidden information in JPEG images. Currently, the detectable schemes are jsteg, jphide, invisible secrets, outguess 01.3b, F5, appendX, and camouflage. Using linear discriminant analysis, it also supports detection of new stego systems. Stegbreak is used to launch dictionary attacks against JSteg-Shell, JPHide, and OutGuess 0.13b.
Fiked is a fake IKE daemon that supports just enough of the standards and Cisco extensions to attack commonly found insecure Cisco PSK+XAUTH VPN setups in what could be described as a semi-MitM attack. Basically, knowing the pre-shared key, also known as shared secret or group password, the VPN gateway can be impersonated in IKE phase 1, in order to learn XAUTH user credentials in phase 2. The configuration supported by fiked is IKE aggressive mode using pre-shared keys and XAUTH. Supported algorithms are DES, 3DES, AES128, AES192, AES256, MD5, SHA1, and DH groups 1, 2, and 5. Main mode is not supported.
