Originally a software partnership between my best friend and myself, Diverse Developments seeks to write "useful stuff", of a very diverse nature... Current projects include a file encoder, and a double-entry accounts package.

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.

IDTrans is developing b2b technologies. The primary aspects of the project are secure transmission libraries, a key server, and a application to demonstrate the use of the libraries.

A standard API for accessing OpenPGP and S/MIME email in JavaMail.

Konfidi is a trust framework that uses topical trust values from a social network of authenticated people. When you receive an email from someone you do not know, but he/she is in the network, Konfidi will compute an inferred trust value for you.

There are a lot of tools and plugins to fix security issues of the dignified mail system. The goal of this project is to redefine a system that takes the problems of our time into account. Be sure to visit this project on github: https://github.com/mv2project/mv2

Securing mails without involving user. Secures them as often as possible if it is possible. Shows security-state and process of mails and mail-partners.

This library extends SUN's JavaMail API by an PGPMime framework. It acts as a middleware layer between a cryptography provider like GnuPG or Cryptix OpenPGP Provider and JavaMail.

Peer Agent is a system that enable a group of users to carry out automated complex interaction via email services without relying on a trusted third party.

Multi-platform spam filtering proxy, designed to be used on the client side. Can be launched as faceless server or with a GUI.

An Experimental Platform for Secure Peer Services, QARE uses a decentralized trust model, a Public Key Infrastructure and provides single logon for multiple applications running across multiple systems. WAR files are used to add applications.

SWM (Secure WebMail) is an applet that provides confidentiallity and authentication in webmail applications using SHA/RSA algorithms. It can accompany virtually every webmail application, but comes with a plugin for squirrelmail and can run standalone.

SlimPGP is a pure Java implementation of OpenPGP protocol as defined in RFC2440. Current version implements most of the features in the OpenPGP.

Spamtools is a java package designed to propose a unified and expendable library for the implementation of experimental spam filters.
