Cryptography Tools is a project to develop demonstration tools on classic (currently Caesar and Playfair) & modern crypto-systems, including private & public key encryptions, digital signatures, cryptographic hashes and authenticated encryption.

hping2 is an interactive packet costructor and responses analyzer that uses the same CLI of the ping program (but with a lot of extensions). It can be used to performs a lot of tasks, like testing of firewall rules, (spoofed) port scanning, et cetera.

The ugtrain is the universal elite game trainer for the command line on Linux under GPLv3. Its dynamic memory support sets it apart. A preloader, a memory discovery and a memory hacking library are included for this. Other features: config file per game, included FOSS game example configs, simplified discovery, security bypassing, automatic adaptation to compiling differences. This project is mostly handled on GitHub: https://github.com/ugtrain/ugtrain

AUM is an extremely fast, small-state, cryptographically secure pseudo-random number generator and stream cipher. AUM exhibits uniform distribution, mixes rapidly, has no detected bias, and comes in three variants: AUM16, with an internal state array of 16+4 32-bit words; AUM32, with an internal state of 32+4 words; and AUM64 with a 64+4-word state. The former permit seeding with a key of up to 512 or 1024 bits, the latter with a 2048-bit key.

BEDBUG is a small, fast, cryptographically secure pseudo-random number generator (CSPRNG) and stream cipher. It exhibits uniform distribution, mixes rapidly (with worst-case avalanche better than 16-bits), has no detected bias, and comes in three variants: BEDBUG128, with an internal state array of 128+3 32-bit words; BEDBUG256, with an internal state of 256+3 words; and BEDBUG512 with a 512+3-word state. The former permit seeding with a key of up to 4096 or 8192 bits, the latter with a 16384-bit key. The BEDBUG generator itself is a mere 5 lines of code: Three rotations; two pseudo-random lookups. The default BEDBUG configuration alternates the rotation constants unpredictably. These four sets of three values differ between BEDBUG128, BEDBUG256 and BEDBUG512 and were selected, tuned and tested in each case for optimal avalanche, which is never less than 16.5 bits. BEDBUG has passed stringent industry-standard tests for randomness, including NIST and DIEHARD.

/!\ Developer(s) needed to optimize routines, multi-processing; any kind of help is accepted :)

The Desktop Environment For Kids is a kid friendly environment for UNIX/Linux, complete with kid oriented desktop themes and desk accesories.

This is a project that simulates the German Military Enigma machine during WWII.. It is a project for beginers to learn to program and to meet people. If anyone is interested in helping, please email me @ dustin@rockhill.org

The kernel network stack may behave not as expected, especially in the case of receiving packets. With Ianus it is possible to bypass the kernel network stack and to develop your own network stack in user space or other tools.

MOTE is a fast, small-state, cryptographically secure pseudo-random number generator (CSPRNG) and stream cipher. MOTE exhibits uniform distribution, mixes extremely rapidly, has no detected bias, and comes in three variants: MOTE8, with an internal state array of 8+4 32-bit words; MOTE16, with an internal state of 16+4 words; and MOTE32 with a 32+4-word state. The former permit seeding with a key of up to 256 or 512 bits, the latter with a 1024-bit key. Reduced to essentials, MOTE is only 5 lines of code: Ten arithmetic and bitwise operations in all. It's called MOTE because a PRNG can't be made much smaller (or faster) without introducing bias or severely reducing avalanche. MOTE alternates its shift and rotation constants unpredictably, and has passed the most stringent industry-standard tests for randomness and security, including NIST & DIEHARD.

This is a module for PAM. It's purpose is to quiz a user who is attempting to log into a system with very simple questions that verify that the entity logging in is human.

This is the worlds first and probably only FLOSS project aimed to create a lowbudget, based on availble technology, cruise missile. No this is not a Joke, its for real. Why? Since no one has tried to do this before and certainly not under the GPL.

SES brings back the uncrackable onetime pad, with a digital twist. It is well known that a random key of message-length is the only provably unbreakable cipher. SES uses cryptographic strength pseudo-random keys of message-length for its many encipherments, in addition to offering true one-time pad capability for the intrepid. SES is built on ISAAC, Bob Jenkins' unbroken CSPRNG, a fast and simple stream cipher placed in the Public Domain in 1996. SES now gives you the ability to efficiently cipher text of arbitrary length or files of any size or type. Use it with confidence. To achieve complete one-on-one privacy, SES traverses several levels en route to its output. The more words in your key-phrase, the more layers of encipherment SES applies. It is part Vigenere, part onetime pad, part cryptographic hash, not to mention the essential scrambler element, each component driven by ISAAC, with all key-derivation and stretching relying on Keccak in 512-bit configuration.

MOTET is a tiny, fast super-encipherment application written in C, featuring the new CSPRNG/stream ciphers MOTE and BEDBUG in each of their three variants, as well as the "gold standard" among ciphers, ISAAC. MOTET brings multiple levels of encryption, including a ciphertext-hash, a Vigenere mixing function, a choice of Caesar MOD or Caesar MIX ciphering on the primary key-stream, plus a deeply scrambled "outer shell" as a final super-encryption stage. A unique nonce IV guarantees that each ciphertext will differ radically from every other, even on the same message and identical key.

The sandbox libraries (libsandbox & pysandbox) are an open-source suite of software components for C/C++ and Python developers to create automated profiling tools and watchdog programs. The API's are designed for executing and instrumenting simple (single process) tasks, featuring policy-based behavioral auditing, resource quota, and statistics collecting. The sandbox libraries were originally designed and utilized as the core security module of a full-fledged online judge system for ACM/ICPC training. They have since then evolved into a general-purpose tool for binary program testing, profiling, and security restriction. The sandbox libraries are currently maintained by the OpenJudge Alliance (http://openjudge.net/) as a standalone, open-source project to facilitate various assignment grading solutions for IT/CS education. See project page at https://github.com/openjudge/sandbox for details.

linsnoop is a unix98-terminal (ptmx) sniffer. Is used to observe a shells input/output. It can be used to observe users, also as keyboard sniffer... Be careful - the module is able to steal passwords!

openSMS4 was created by tao.tang316 and implemented in C, which is an open source implementation of the SMS4 encryption algorithm (including simple checking codes).

rjudge is a judge system for the Olympiad in Informatics. It can be also used as a problem test tool in the programming contest and daily practice. It provides many security features to ensure the smooth implement of judgement.

The aim of the project is a lightweight intrusion detection library for embedded devices which supports MSP430 and ARM Cortex based devices. Features include DSP/SIMD support, IoT and embedded protocols, distributed operation, event and history management, tool supported configuration and visualization. There is a Java port that supports less features.
