Mixmaster anonymous remailer

Mixmaster is an anonymous remailer software which sends messages in fixed-size packets and reorders them, preventing anyone watching the messages go in and out of remailers from tracing them. Mixmaster was originally written by Lance Cottrell, and is now maintained by Len Sassaman. Current Mixmaster software can be compiled to handle Cypherpunk messages as well; they are needed as reply blocks for nym servers.
