[FAQ 3.6] What is a Mixmaster Remailer?


Also known as a Type II remailer, this kind of remailer accepts
messages in the Mixmaster format. It doesn't use a PGP key but instead
it uses it's own Mix key which looks like something like this:

-----Begin Mix Key-----
08daa0412580b473b0405a27b6eb72f6
258
AATLm+Il10etAgaOBsAMfggFXi2ghiyypIkZkqhh

VHlOpyeHRfJNIQAAAAAAAAAAAAAAAAAAAAAAAAAA
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
AAAAAAAAAAAAAAAAAAAAAQAB
-----End Mix Key-----

Mixmaster uses a message format based on RSA and Triple-DES
encryption. Messages are multiply encrypted and formatted so as to
appear identical to other Mixmaster messages . Messages are sent
through chains of Mixmaster remailers. Each remailer removes one layer
of encryption, and forwards the message. When the final remailer
delivers the decrypted message to the recipient, it is impossible to
find out where it came from even if part of the remailer chain is
compromised.

Mixmaster remailers improve on Cypherpunk remailers by making traffic
analysis much more difficult. It does this by making all incoming and
outgoing messages the same size (28.1kb) and by re-ordering messages
before delivery - so that traffic coming in cannot be associated
necessarily with traffic going out.

The building of a Mixmaster message cannot be done with a text editor!
Special client software is required.
