Setup Your Own Mixnet
Katzenpost is still pre-alpha.DO NOT DEPEND ON IT FOR STRONG SECURITY OR ANONYMITY.
Mix networks are meant to be decentralized and therefore should be operated by multiple entities. You can of course be the only operator of a mix network for testing purposes.
Take a look at our docker repo. This will explain how to configure and run a katzenpost mixnet.
A Katzenpost mix network has two binary programs, a
PKI and a
Katzenpost server side requires a recent golang. See golang install instructions: https://golang.org/doc/install
Follow the build instructions for each Katzenpost component repo.
The produced binaries are statically linked, so you can build the authority and the server code on one machine, and then distribute them to any Linux based machines to run.
Each network component, the PKI and mixes/providers, MUST have the correct time. We recommend chrony for the purpose of time synchronization.
apt install chrony
Add Users to the Provider
This step might not need to be performed if you are using a client that auto-registers users with their Katzenpost Provider; such as catchat.
User to the
Provider using the management interface:
socat unix:/<path-to-data-dir>/management_sock STDOUT
ADD_USER alice X25519_public_key_in_hex_or_base64
In case you want to use the automatic key discovery for mailproxy, the user identity key (identity.public.pem) also needs to be set:
SET_USER_IDENTITY alice X25519_public_key_in_hex_or_base64
