Mover is a system designed to move mail while eliminating as much metadata as possible. In fact, it eliminates virtually all metadata, except for the order and possibly the time that a message arrives at a given site. Addresses are encryption keys. The encrypted messages are sent to all mover locations. The intended recipient uses their key to decrypt the message.
Release Notes: This version appears to work enough to be somewhat useful. Currently, OpenSSL and GPG encryption are supported. The beginnings of support for One Time Pads are included as well. There is currently no documentation or user friendly interfaces.
