A cypherpunk anonymous remailer is a Type I anonymous remailer that takes messages encrypted with PGP or GPG, or in some cases in plain text, and forwards them removing any identifying information from the header.

Sending a Cypherpunk Message

Step 1: Retrieving the remailer's Public Key.

Step 2: Import remailer's public keys into PGP or GPG.

Step 3: Compose Message

::
Anon-To: <Recipient Email Address>

## Subject: <Subject> <Message Text>

Step 4: Encrypt Message

Use PGP or GPG to encrypt the message that you just composed.

Step 5: Send Encrypted Message to Remailer

Prepare an email to send to the Cypherpunk remailer using the following template:
::
Encrypted: PGP

-----BEGIN PGP MESSAGE----- <place encrypted output here> -----END PGP MESSAGE-----

Then send it.

[edit] Notes

  • The extra headers are called 'pseudoheaders' because they do not appear in the RFC 822 headers specification for email.
  • Messages to Cypherpunk remailers may be layered so they route through several different Cypherpunk remailers to decrease the odds of anyone determining who the sender is.
  • Some Cypherpunk remailers are also Mixmaster anonymous remailers and can split long Cypherpunk messages into Mixmaster packets and send them to the next remailer, if it also understands Mixmaster.
  • Many Cypherpunk remailer users will repeat steps 1-4 to wrap their message in additional layers to route it through several remailers for additional privacy and security.
