gpg-wks-server - Server for the Web Key Service
gpg-wks-server [COMMAND] [OPTIONS] [ARGS]
gpg-wks-server is a server for the Web Key Service. It can handle incoming mails with the --receive command. See the EXAMPLES section for procmail and crontab configurations. You also need a webserver configured to alias requests to /.well-known/openpgp/ and below to the /var/lib/gnupg/wks/<wkd-domain>/ directory.
--receive Receive a submission or confirmation. --cron Run regular jobs. --list-domains List configured domains, and checks some file and directory permissions. --version Show program version and some meta information. -h, --help Output a short usage information. --warranty Print warranty information. --dump-options Dump all available options and commands.
-v, --verbose Enable verbose output. -q, --quiet Be somewhat more quiet. --send Send the mail using sendmail. -o, --output FILE Write the mail to FILE. --from ADDR Use ADDR as the default sender. --header NAME=VALUE Add "NAME: VALUE" as header to all mails. Can be used to add a header for loop detections, see procmail example. --debug Set debugging flags. All flags are or-ed and flags may be given in C syntax (e.g. 0x0042) or as a comma separated list of flag names. To get a list of all supported flags the single word "help" can be used. --gpg GPG Use the specified command instead of gpg.
/var/lib/gnupg/wks/ Contains a subdirectory for each domain to run the server for. Each subdirectory is supposed to contain what should show up on https://.../.well-known/openpgp/. The user running gpg-wks-server needs write access to these subdirectories.
~/.procmailrc Store received emails in ~/Mail/ (create it manually first), uses From: firstname.lastname@example.org and X-WKS-Loop: example.com as loop detection: MAILDIR=$HOME/Mail LOGFILE=$HOME/Mail/from LOCKFILE=$HOME/Mail/.lockmail VERBOSE=yes # filter out FROM_DAEMON mails (bounces, ...) into separate mailbox :0 * ^FROM_DAEMON from-daemon/ # archive (copy!) all "normal" mails :0 c archive/ # if not in a loop: handle mails with gpg-wks-server :0 w * !^From: email@example.com * !^X-WKS-Loop: example.com |gpg-wks-server -v --receive \ --header X-WKS-Loop=example.com \ --from firstname.lastname@example.org --send # if handling failed: store in separate mailbox :0 e cruft/ ~/.forward In case procmail is not used automatically the following ~/.forward file might be useful: "|exec /usr/bin/procmail || exit 75" The double quotes are supposed to be included in the file! crontab You should run the --cron command once a day. Edit the crontab with crontab -e and append the following line: 42 3 * * * gpg-wks-server --cron
