-- This hook reads the 'passphrases' file from the confdir.  It expects the
-- file to be formatted as follows:
--
-- key@domain.tld "passphrase here"
--
-- One entry per line.  The quotes are required.
--
-- Note: Because the file contains passphrases it should only be readable by
-- select users.
