I have just uploaded a project to google code that I have been working on, it is called XDP, which stands for eXtended Data Protection.  It is like the Microsoft DPAPI, except better!

Why is it better?  Well the DPAPI only lets you encrypt data locally to yourself or the machine, whereas XDP allows you to encrypt data to another local machine user or group, or if you are part of a Domain, you can encrypt to other Domain users and Domain groups.  What makes XDP different to other technologies like PGP or GPG is that, like the DPAPI, it does not require the user to worry about key management, as it uses the DPAPI to manage keys.  It is the only non-certificate method I know of to encrypt data to other people in a Domain environment.

Feedback welcome!
