FONC (FTP Over Normal Connections) allows both active and passive FTP transfers via normal port connections. This allows FTP (both control and data transfers) over simple ssh tunnels among other things. FONC is easy to setup, and runs anywhere java can.

Automated Fuzztests for JUnit

A very simple port scanner written in Java with multi-threading. I have not add any special features in the first release. Feel free to modify it.

Bridge between SAML v2.0 and WS-Federation.

The EaseFilter Filter Driver SDK is a collection of tools, libraries, and sample code designed to facilitate the creation of Windows file system filter drivers. These drivers operate at a low level, intercepting file I/O requests before they reach the underlying file system or other filter drivers. The EaseFilter SDK provides a powerful interface for developing Windows filter drivers in C++, C#, or other programming languages that support native DLL calls. This guide helps developers understand how to use the SDK effectively to monitor, filter, or control file system activities in real time.

Encoder.jar utility enrypts any file (containing text like .txt, .rtf, .html, .htm, .msg, .xml, etc.) and generates an encoded file. This encoded file may then be transferred via email or other medium from the source machine and can be decoded back to original on the target machine. The target machine should have Decoder.jar in order to reproduce it back to the original form. Decoder.jar decrypts an encoded file and regenerates the original file. Use : java -jar Encoder.jar java -jar Decoder.jar

FileMan is a file manager software that allow users to apply multiple functions to all kinds of files such as : AES encryption/decryption, zip archiving, file spliting/merging , file comparison.

The EaseFilter File Control SDK is a powerful development toolkit for creating robust, kernel-level file security and data protection solutions on the Windows platform. It includes a high-performance file system filter driver that intercepts and manages all file I/O operations in real time, giving developers deep, granular control far beyond what is possible with standard Windows APIs or Access Control Lists (ACLs). The EaseFilter Control Filter Driver provides a powerful method for intercepting file I/O operations at both the pre-operation and post-operation stages. This dual-layered interception enables comprehensive monitoring and enforcement of file access policies.

Firing Range is an intentionally vulnerable web application designed to evaluate the real-world effectiveness of web security scanners and training exercises. Deployed as a cloud-friendly app, it aggregates dozens of vulnerability patterns in repeatable, labeled routes so tools can be benchmarked on coverage and noise. The project doesn’t just include simple XSS forms; it spans variants such as DOM-based issues, context-sensitive sinks, template mishandling, CSRF, open redirects, and mixed content problems. Each scenario is crafted to reflect how bugs appear in production—behind frameworks, in odd encodings, or across redirects—so scanners must demonstrate accurate crawling and context understanding. Because the behaviors are stable and documented, teams can run comparative tests over time and quantify regression or improvement in their pipelines. It’s equally useful for human training, giving analysts a safe playground to practice exploitation and triage skills.

First Wall is AntiSpyware program. Block spyware to track your system, calling dialers, change browser options...

The Flow Controller is an implementation of the controler layer of the MVC pattern, using a servlet and a XML based flow description. The Flow Controller has transparent support for HTTPS and file uploads.

EaseFilter Folder Locker is a Windows file and folder protection solution built on the EaseFilter File Control, Encryption and Process Filter Driver SDK. It lets you lock, hide, and restrict access to files and folders in real time to prevent unauthorized access or modification. With the folder locker you can prevent your protected files being read,written,deleted, renamed, copied out of the protected folder, allow you to authorize or deny the file access to specific user or process, also allow you to hide the files or automatically encrypt/decrypt the files

Time-stamp of a created file can be modified by attacker. This project is meant to track File timestamp values , using NTFS data structures rather than trusting the original time stamp modified by attacker.

A collection of useful Java classes.

This package implements the FF1, FF3, and FFX algorithms and the A2 and A10 parameter sets for format-preserving encryption. The FF1 and FF3 methods for format-preserving encryption are implementations of NIST Special Publication 800-38G, Recommendation for Block Cipher Modes of Operation: Methods for Format-Preserving Encryption. The FFX algorithm and A2 and A10 parameter sets are implementations of "The FFX Mode of Operation for Format-Preserving Encryption," by Mihir Bellare, Phillip Rogaway, and Terence Spies. For more information see the README.txt and package-info.java files in the source.

FragMend is a GUI tool that allows a forensic investigator to classify and view sectors of raw or unallocated data. The sectors can then be ordered and grouped into files.

This project contain chat server and chat client/admin that works on Windows/Unix.. This is a Free software. Developed by Osama Mohammad Oransa, 2009,contain 3 parts : Chat Server ,Admin and Chat Clients, Based on Java RMI, will support XMPP soon.

The end goal of the FreeMess Project is to produce a cryptographically secure, pseudonymous, cross-platform peer-to-peer Instant Messenger service, piggybacking on FreeNet (http://freenet.sourceforge.net) as a distributed filesystem to hold user data.

Freemail enables secure, anonymous, two-party communication over Freenet. The use of flexible channel initiation protocols and secure message transport allows allows cultivation of anonymous identities with reliable reputations.

FroZenLight connects simple line art and mathematics. The source of light can be positioned so that either symmetric reflection patterns or secret messages (Cryptography) are created. Example light patterns and math exercises for education are provided.

This programm is able to block your computer. so other people are only able to access you computer if they know how to use the program and if they know your personal password.

The Ganymed SSH-2 for Java library (implementing the SSH-2 protocol) allows you to connect to SSH servers from within your Java programs.

Ganzúa is a cryptanalysis tool for classical ciphers (mono and polyalphabetic) that lets the user define almost completely arbitrary cipher and plain alphabets, allowing for the proper cryptanalysis of cryptograms obtained from non-English texts.

We at GCD are here to bring you ease in decoding your friends CRYPTIC GeekCode .signature files -=). Also sometime in the future we plan to eventualy start an ENCODER to help you even more!

GenerateAndDownloadHash is a servlet that generate checksums in GNU-style. Has been tested on WildFly 10.1/Tomcat 9/Tomcat 8. See src/config.properties for configuration.
