Playground release

Katzenpost is still alpha. DO NOT DEPEND ON IT FOR STRONG SECURITY OR ANONYMITY. This playground does not provide any anonymity whatsoever.

This release of the Katzenpost mailproxy is to be used with our public test mix network. Furthermore you should expect us to remove this demo service when our testing period is over at some arbitrary time in the future.

Please consult the Katzenpost Handbook for more information: https://katzenpost.mixnetworks.org/docs/handbook/

0. Install the latest github release of this software (versions v0.0.2 or later) that is suitable to your operating system and hardware architecture, found here:

   • https://github.com/katzenpost/playground/releases

1. Run the registration program to register your account on the mix network:

   katzenpost_registration -name alice
   

   The above example creates the "alice" user on the "playground" provider and is therefore addressed as alice@playground.

   This registration process uses HTTPS without Tor by default. If you already have Tor on your system you can register using our onion service like this:

   katzenpost_registration -name alice -onion -torSocksAddr 127.0.0.1:9050
   

   Or if you run the Tor Browser Bundle with the default Tor setup then simply:

   katzenpost_registration -name alice -onion
   

2. The above command should have printed "Success" and created a ~/.mailproxy directory containing various coniguration files including key material. You will now be able to run mailproxy like so:

   mailproxy -f ~/.mailproxy/mailproxy.toml
   

3. Configure your e-mail client to use mailproxy. That is to say, mailproxy exposes POP3 and SMTP services which your e-mail client should be configured to use:

   POP3 at 127.0.0.1 on port 2524
   SMTP at 127.0.0.1 on port 2525
   

   Here's one possible solution: 1. install thunderbird:

   sudo apt install thunderbird
   

   2. Launch thunderbird and go to the Edit menu:

      • select Account Settings
      • click on the Account Actions drop down menu and select

      Add Mail Account. After clicking OK you should be presented with a configuration window that lets you specify incoming and outgoing mail settings. Click the drop down menu for incoming and select POP3. Set the POP3 server hostname to 127.0.0.1 and set the POP3 port to 2524. Next set the SMTP hostname to 127.0.0.1 and the SMTP port number to 2525. Select None for both drop down menus that by default specify TLS is used. Set POP3 authentication to Normal Password and SMTP authentication to No Authentication. POP3 authentication username must be set to alice@playground where alice is replaced with your username that you registered with. The password can be set to anything.
