OpenWAF
Web security protection system based on openresty
The first all-round open source Web security protection system, more protection than others. OpenWAF is the first fully open source Web application protection system (WAF), based on nginx_lua API analysis of HTTP request information. OpenWAF is composed of two functional engines: behavior analysis engine and rule engine. The rule engine mainly analyzes the individual requests, and the behavior analysis engine is mainly responsible for the tracking of the request information. Rule engine... -

ParamIT
a Toolset for Molecular Mechanical Force Field Parameterization
...The developed toolkit helps the researchers in following ways: 1) automating the creation of multiple input files for quantum and molecular mechanics programs, 2) automating the output analysis and 3) substitute the use of full MM programs with a faster specialized one. The developed tools include: 1) generator of molecule-water complexes with graphical user interface (GUI), 2) semi-automatic frequency analysis using symbolic potential energy distribution matrix and comparison of optimized internal coordinates, 3) GUI for charge fitting with three modes: manual, Monte-Carlo sampling or brute force, and 4) GUI for dihedral terms fitting. ... -

tinfoleak
OSINT tool for extracting and analyzing Twitter intelligence data
tinfoleak is an open source intelligence (OSINT) and social media intelligence (SOCMINT) tool designed to automate the collection and analysis of data from Twitter. It focuses on helping analysts extract large volumes of information from Twitter timelines using identifiers such as usernames, geographic coordinates, or keywords. Once the data is gathered, tinfoleak organizes it into structured information that can support intelligence analysis and investigative research. tinfoleak is capable... -

Simple Cipher Decoder
Decrypts and encrypts substitution, transposition and vigenere ciphers
Change log 1.01: 1)Error fixed on clicking solve and arrow buttons in the vigenere decoder 2)Error fixed when number of columns exceeds text length in substiution cipher 3)Can now handle variable block length when changing columns 4)Multiple identicle conversion values onn the frequency analysis page now not allowed This project is near its final stages but there may still be improvements to be made. If you could write some form of review or send me an email with advice I would greatly appreciate it. This is a series of three simple programs that will allow you to easily encrypt and decrypt text using any combination of substitutions, transpositions, vigenere ciphers or caesar shifts. ... -

The Alpha-Padding Permutation Cipher
Read this post: http://codijuana.blogspot.com/2013/10/case-2-alpha-pad
Remix of the permutation ciphers' design for better security. I tried to solve the issue of frequency analysis and brute force attacks by joining padding and the alphabet matching (I called it the alpha-padding) View a demo here: http://igenda.netau.net/codijuana/alphapadding_permutation/ -

Substitution Cipher Decryption
Decrypt messages encrypted with a substitution cipher
...Ciphertext can be modified at any point of the process. • Easy location of corresponding characters in the ciphertext and the substituted text by selection. • Fast frequency analysis for single letters, bigrams, trigrams and quadgrams (more N -grams can be made available by adding a single line of code). • Showing the most common letters (bi-/trigrams) in the ciphertext compared to the most common letters (bi-/trigrams) in the British English language. • Easy assignment and change of the substitution letters... -

vigenere.py
this simple program implements the Vigenere cipher in python
For details of this cipher see; http://en.wikipedia.org/wiki/Vigenere_cipher This cipher can be broken by frequency analysis, this is a toy project, and should not be used in situations where security is important. -

ENIGMA 2000
ENIGMA 2000 is a reliable file encrypter for DOS shell
ENIGMA 2000 is a symmetric cryptographic algorithm developed in C++ for Windows, to encrypt any file. It is not optimized for speed processing but it is extremly reliable. Tests state that a huge input file just with zeros, will return an output file whose frequency analysis is white noise. It uses six phases to encrypt any file and the phases sequence depends on the password. On phase 5, it uses the Rubik's cube paradigm to encrypt the data. It's extremly reliable and the password varies between 8 and 16 characters. The execution syntax is: coder.exe [file to encode] [password (min 8 char, max 16)] [mode ('c'oder 'd'ecoder)] Enjoy it -
