The goal of this project is to create a GnuPG front end for Mac OS X. To that extent, it will make installing GnuPG on OS X easier and provide inter application services to access GPG. Also, GPGME wrapper in ObjC will be done.

WASTE is a mesh-based workgroup tool that allows for encrypted, private communication between distant parties on the internet, independant of local network organization.

Codegroup is a Java application that will allow one to convert binary (or text) computer files in to 5 letter codegroups for transmission over email, landline telephones, radioteletype or Morse Code.

The Mav.Crypt tool will be upgraded to many different encryption methods. At the Moment, the only method is ROT13, but we are developing some other technics and a new Algorithm. More Infos shortly at the Project Web Page.

This is a library for easy accessing chip cards /smart cards via a chipcard reader. It currently works under Linux, FreeBSD and Windows. It is tested with Towitoko and Kobil readers.

This package provides the following pure Java extensions to the Bouncy Castle framework www.bouncycastle.org and was made freely available by www.novosec.com: 1. OCSP (RFC 2560) server and client / 2. CMP (RFC 2510, RFC 2511) generator and parser
