Three software packages to work with RFC2617 digests: libdigest (C library to compute digests), libcppdigest (C++ library to manage /etc/passwd-like files) and libpam-digestfile (PAM module allowing authentication via an /etc/passwd-like file)

The Watermarks is a java library for images and text watermarking fingerprinting and tamper-proofing. The supported carrier formats for a watermark are JPEG and PDF. The project also aim to build a test environment to evaluate robustness of implemented a

This is a collection of vb class modules written in native Visual Basic. They provide the following functionality: Processing of very large integer numbers, hashing algorithms, prime number handling and an implementation of the RSA algorithm.

This is a tool that uses a combination between a brute force and dictionary attack on a Vigenere cipher. At present, keys are generated using brute force (will soon try passwords generated from a dictionary first). Each key is then used to decode the encoded message input. The output is analysed and then put into a ranking table. Outputs will be ranked on a variety of factors (at present, only number of dictionary words in output are counted). For the future: Better key generation, trying combinations of dictionary words with numbers. If that fails, brute force will be used. For all attempts of the dictionary attack, only keys within the known key length range will be generated. Better ranking system and analysis of possible decoded messages. Note: The version currently released, I made in an evening! It is nowhere near ready for release but is a fun project to think about and I need more ideas for improvements mentioned above. Discuss possible solutions and ideas!

This a .net 4.5 WPF application that generates word lists, similar to crunch for linux. Just one nifty multi-threaded dictionary / code / word - list generator. It is a permutation combination engine, so it is perfect for brute force activities. Please show your appreciation and leave a review or comment, so I can find the motivation to improve it.

WORDFIELD is an extremely fast incremental word list generator. It's meant for use with a password recovery tool such as John the Ripper or aircrack-ng.

Wireless DCC, Digital Command Control for model railroad over 802.15.4 the network nodes being the handhelds and the DCC decoders themself. Backward compatibility with DCC will be kept but new users wont need command stations and boosters.

antigift could be used for encryption files & folders on USB-flash or HDD partition. Works on Linux (including Android), Windows, Mac OS X, FreeBSD, DragonFly BSD and other on OSes. Do not required installation. Include WIPE tool for wiping free space and tool for recovery forgotten key. See documentation at http://sourceforge.net/p/antigift/wiki/Home/ antigift простой и кросс-платформенный инструмент для шифрования файлов и папок(с ccrypt в качестве основы) Подробности см. на страничке с русской документацией http://sourceforge.net/p/antigift/wiki/rus/

Common Lisp provides a SEARCH function to lookup given keys in a string, but its implementation can be subotimal: it can be beaten in some cases by even the simpliest brute-force algorithm. This project is aimed at implementing robust string matching algorithms for Common Lisp.

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.

Flash/PHP adaptation of the XTEA encryption algorithm. Allows encryption/decryption of sensitive data using 128-bit key. May be used for network data (HTTP) or offline for implementations like secure CD-ROM projects.

A Collaborative Attack on Complexity to Create a New Global Way of Life

The gruft library is a fast implementation of several cryptographic functions in JavaScript: MD5, SHA-1, SHA-256, Tiger/192, AES-Rijndael.

The name leet stands for "Linux exquisite encryption tool", it will be a software application for on-the-fly encryption, similar in its functionality to TrueCrypt. The goal of leet however is to be simpler and as user friendly as possible, making encryption and securing of information accessible to anybody, even those who don't necessarily have any prior knowledge of data securing, algorithms and encryption. However it's not targeted at this group of users only, part of the ambition of this project is to reach companies, institutions, governments (etc...) as well.

Libnsa stands literally for "Library: Non Semper erit Aestas". It is a small C++ library which implements RSA encryption. The current version only creates the 4096 bit public and private keys.

Textcrypter is an encryption tool using vigenere cipher algorithm. Vigenere use the same key/password to encrypt and decrypt a file (symmetric key cryptosystem). Result of the encryption process is a ciphertext in hexa number.
