cross-plattform user interface for gnu-pg

xhelix: python C extension implementing Helix encryption and authentication. Based on the article named "Helix: Fast Encryption and Authentication" by Niels Ferguson and Bruce Schneier, published in the Nov 2003 issue of Dr Dobbs Journal.

xmlsig is a multi-language, multi-platform implementation of XML signatures.

yubikey-agent is a seamless SSH agent specifically built for secure hardware tokens such as YubiKey (and other PIV tokens). It aims to replace the standard SSH agent with a version tailored for these security devices; the key is generated on the hardware token (so it can’t be extracted), every session requires a PIN and a physical touch, and the agent is resilient to unplugging, sleep/suspend, and restarts. Setup is simple, one command and one environment variable, and then the agent just runs in the background. Because it uses pure Go and leverages libraries like go-piv/piv-go and golang it works across platforms and integrates cleanly into SSH workflows. For developers or administrators who prioritize hardware-based SSH key security, this tool lowers the friction of using secure tokens in day-to-day SSH workflows. It also supports modern best practices in SSH authentication and brings stronger guarantees of key security in a user-friendly interface.

One of the project groups in Intake 6 is planning on doing a IM client which is secure. This includes messenging, file sending, picture drawing, video transmissions by far.

A smart card-based public key cryptography system based on elliptic curves, using AES for session key generation and SHA for hashing. This project will include the smart card software, terminal software, and a public key server.

A powerful, provider-based .NET CAPTCHA control with audio challenge and Microsoft Visual Studio design-time support.

HcryptoJ (Historical cryptology in Java) is a Java based programming library for implementing and analyzing historical ciphers. HcryptoJ is designed to support research and teaching in historical cryptography and computer science. Licensed under GPL.

This is a free and open source java library to generate license for your application. Use this library to make your custom license file with your own extension. It encrypts the license file with the one time pads encryption technique to make it hard to break. The generated license file can be set to expire after certain time, and also can be set to expire manually after a certain action.

This project provides a steganography tool that allows to know, use and compare the results of current steganographic techniques. It also incorporates a comprehensive set of stegoanalitics methods for images.

A multi-platform tool to convert RSA private keys between SFM format (modulus, public exponent, private exponent) and CRT format, in both ways.
