    Vigenere Dictionary Attack

    Vigenere brute force / dictionary cracking tool

    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!

    XOR encrypt v2.0

    XOR encrypt v2.0

    Encrypt Your Text documents with XOR encryption

    This software provides an easy graphical way to encrypt your text documents from source code , text files ,scripts even jpeg files .It is a enhanced version of my earlier project https://sourceforge.net/p/xorencrypt which used win32 GUI . This is a demonstration of working of XOR encryption which was used by Germans in World War II (http://en.wikipedia.org/wiki/Lorenz_cipher) . Besides from XOR'ing the message with password after every encryption the key changes pseudorandomly. The password you provide is hashed ( SHA256 ) and saved into the encrypted file to check if the password provided is correct.This algorithm has limitations in general more the numbers of relative characters in the password to plaintext more secure will be the encryption. XOR encrypt has a 3.5 of 5 editors rating from softpedia http://www.softpedia.com/get/Security/Encrypting/XOR-Encrypt.shtml

    leet

    leet

    Leet is CCEx's software application for on-the-fly encryption (OTFE).

    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.

    WPF Code Generator

    WPF Code Generator

    Word List Generator for Windows

    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.

    cl-string-match

    String matching algorithms implementation for Lisp

    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.
