arcsign - Script for ARC signing messages on stdin


arcsign is a filter that reads an RFC822 message on standard input, and writes the same message on standard output with a ARC-Signature lines prepended.

The signing options are specified on the command line:

arcsign selector domain privatekeyfile srv_id

Note: arcsign will only use authentication results header fields with an authserv-id that matches srv_id as the input fields for the ARC chain.

This version of arcsign was written by Brandon Long <> and is derived from dkimsign, written by Greg Hewgill <>.
