It moves by itself inside networks like virus infection & plagues, it is being written to solve computer virus problem drastically and responsibly. It is legal, free and open for public domain to improve W3 ICT Security.

Java implementation of the most commonly used algorithms for exact string matching, where the pattern is given first.

The Latin Square Toolbox contains software tools for efficiently generating Latin squares and counting their transversals with various user-configurable options. This open source release aims to help educate folks on Latin squares and their important applications to cryptography. This version contains three tools: 0. Latin Square Generator (LSG) 1. Latin Square Transversal Counter (LSTC) 2. Latin Square Property Checker (LSPC)

This project provides an implementation of the NTRU public-key cryptosystem: NTRUEncrypt and NTRUSign.

Java module to create, read and write Password Safe V3 encrypted databases. The package is a mature offspring from project JPasswords and can be used with Java 1.8. There is an API document available.

Sha4j is a one class implementation of SHA-1, SHA-224, SHA-256, SHA-384 and SHA-512 algorithms.

Fills a rectangle using given tetris shapes (tetraminos) using an optimized brute force algorithm. A puzzle can have many different solutions; this solver will stop at the first one. Not all puzzles are solveable. Created to solve the annoying tetris puzzles in The Talos Principle and Sigils of Elohim.

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

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.

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.
