ContraCaptcha is a Java-based libary for solving (image-based) captchas. It provides classes for image processing and character recognition. It also includes solvers for some of the popular captcha-systems in use DISCLAIMER: only for learning purpose (;

A multi-user password management web application designed for organizations to store passwords. Written in Grails, Groovy and Java.

cravlAndBlock is simple java application that cravl error log file of Your web server and add all attacker IPs. I.E. All Modsecure entries, scans and so on. Every bad IP will be added to hosts.deny file with ALL prefix. For sure it will not block all atacks but it will help. How it works: use cron to start java cravlAndBlock.jar in the same folder add properties.xml (I addes sample properties.xml file). And thats all. Program will start from cron, read properties file and make backup of hosts.deny file in backu location, cravl log file / files and add entries to hosts.deny file. It will print log information on the screen. If You are interested in cravl and block project please make a small donation for the author by paypal (to mail tjancz@gmail.com). Those donation will make the project live. Everyone needs to eat something:)

crcRepair is a utility that is able to fix corrupt files by consulting a database and file mirrors. It is written in pure Java, so it can be used on all platforms with the Java JRE installed.

This is a java native wrapper, based on JNA of standard methods to access smart cards (pkcs11, pc/sc, openct, libusb). Goals of this projects are: * interoperability: it can work on any platform where JNA runs: Windows, Linux, Mac (and one day even Android) * modularity: you don't need to include pc/sc support if you only use pkcs11 * ease of integration: it depends only on few required libraries. * ease of use: it exposes a simple java interface (even if you can deal with the JNA classes directly)

COMMON VULNERABILITIES AND EXPOSURES (CVEŽ) DATABASE BROWSER, CVEBROWSER A web search engine for the CVE dictionary, targeted to be used on a intranet. CVEBrowser uses Java Servlets / JSP and MySQL and its designed to work well on RedHat

D-crypt is an symmetrical block cipher operating on 256bit blocks with an key of the same length. The cipher takes 3 inputs: the data to encrypt, the symmetric key and a tweak consisting in a array of 16 integers representing each one of eleven possible keyaddition algorithms. Features a similar structure as AES (uses simpler versions of ShiftRows, MixColumns) and uses AES SBOX. It is an SP network. The Key Schedule is a different from AES's, however the Expansion is partially inspired in AES. The 256-bit key is turned into a 576-byte expanded key which is used in every key addition round. D-crypt performs a total of 18 rounds: Firstly it does a SBOX round, and a XOR keyaddition with the first 32bytes of the expanded key, Secondly it does 16 rounds of MixcColums, ShiftRows, KeyAddition (this step is determined by the tweak) and SBOX, and finally, it does an final round of SBOX followed by a final round of XOR key addition, providing key whitening. Only 32byte and key supported for now

XTEA (eXtended Tiny Encryption Algorithm) support for db4o open source object database. XTEA is a block cipher that operates on a 64-bit block size with a 128-bit key. An extremely tiny but very fast encryption algorithm (with cycles less than 32 rounds)
