Whether on our cloud or self-hosted, create the internal software your team needs without compromising enterprise standards or control.
This project aims at porting visual cryptography, which only works with transparent slides, to ordinary 80g/m^2 white paper. Please read the documentation before using the program.
Kotak is just another cracking tool which is based on Java. It is used to crack various types of hash functions with various types of attacks. It's developed to be as simple as possible, so that anyone can use this tool easily.
Kryptographie is a student project to implement historic encryption methods. It has a linux style commandline interface. This project will also include the notes for my talk I'll hold on cryptography in school. (in German).
A very simple file encryption tool. Release 1 is a text editor that saves encrypted files. Release 1.1 will include the ability to convert any file, even binary, to a GEF (Gulosh Encrypted File). Release 2.0 brings the strong encryption into play.
Provides a Java implementation of various Attribute Certificate (AC) functionalities. In particular, it provides various client interfaces to the Virtual Organisation Management System (VOMS) system, as well as an AC server that can act as a VOMS Server.
If you need to protect your confidential files in office or shared desktops, here is the robust commandline and GUI utility to do password based encryption using AES. It can encrypt and decrypt a folder structure containing any number of files.
Java project.

GUI aswell as console functionallity.
Options to include a key salt inside of the jar to hinder bruteforce attempts.
Java based Portable hashing application capable of multiple individual file signatures or proprietary group signatures (1 signature for a folder and all its contents). GUI and commandline in the same executable. -sha1 -sha256 -sha51 -md5 -crc32
Easy-SEND is an implementation of the SEND (SEcure Neighbor Discovery) protocol for IPv6. It is aimed to be used for learning and testing purposes. SEND is described in RFC 3971. Easy-SEND includes a tool (CGAGen) to generate and verify CGAs (RFC 3972).
Shasummer is a SHA hashsum utility in Java. It can calculate SHA1, SHA256 and SHA512 hashes of a file or of a directory (and its subdirectories) and verify the hashes later. Shasummer has a graphical and a command-line interface.
Project Sypher is a Java program that is intended to take a document and cipher the text, output the result in a new document and delete the original file.
SJEA version 1.0 - Simple Java Encryption Algorithm. SJEA is a simple command-line binary encryption algorithm (symmetric block cipher) written in JAVA. It uses a password and a byte-vector array to scramble the input file.
Secure Storage service is a set of tools to store in a secure way and in an encrypted format confidential data on the grid storage elements. The service has been designed for the grid Middleware of the EGEE infrastructure, gLite.
