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...

...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 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...

...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...

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.

CryptoHawk can calculate hashes (md2,md4,md5,sha-1,sha-256 and hmac). It can also perform cryptanalysis like frequency analysis for substutition cipher and exhaustive key search for rotation cipher, as well as searching internet databases for md5 hashes.

CryptoHelper is a Java program designed to aid in the decryption of classical ciphers, ie pre WWII ciphers. It brings together tools like frequency analysis, friedman tests, enciphering/deciphering for several clasical ciphers, and brute force algorithm
