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)

Cumulus4j is an encryption plug-in for DataNucleus. Applications can thus use JDO or JPA to persist their data into every common database. Using the Bouncy Castle cryptography libs, it provides strong encryption via AES, TwoFish or other algorithms.

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)

Export Import Directory Tool to help building metadirectory

A secure PKI-based client/server encrypted chat engine under development in Java. Encryption will be supported via JCE and PKCS#11. A simple Java interface can be implemented by other projects wishing to develop a Java GUI or CLI for the client.

encrypted-dns is a repository of configuration profiles for encrypted DNS on Apple devices. It provides mobile configuration files for DNS over HTTPS and DNS over TLS providers, making encrypted DNS setup easier on iOS, iPadOS, and macOS. The project organizes multiple provider options so users can choose a resolver and install the matching profile. Its goal is to make privacy-oriented DNS configuration more accessible without requiring manual network profile creation. It also includes multilingual documentation and contribution guidance for adding or updating providers. The repository is useful for users who want simpler encrypted DNS deployment and for maintainers who need a structured catalog of Apple DNS profiles.

Open Source Encryption and digital signature libraries for JMS. These librararies are writen in java and are to support secure integration through middelware/ISB/ESB

A robust and reliable user management sub-system is critical to an enterprise application system. Esecurity is a web services-based user management component that provides services for user authentication, access control, user profile management etc.

The goal of the project is to develop Role Based Access Control software which can be used in any application. The software can be deployed as a server which can cater to multiple applications. Rules can be written for fine grained access control.
