DESCRIPTION

       The  gpg-wks-client  is  used  to  send  requests  to a Web Key Service provider.  This is
       usually done to upload a key into a Web Key Directory.

       With the --supported command the caller can test whether  a  site  supports  the  Web  Key
       Service.   The  argument  is  an arbitrary address in the to be tested domain. For example
       ‘foo@example.net’.  The command returns success if the Web Key Service is supported.   The
       operation  is  silent;  to  get  diagnostic  output  use the option --verbose.  See option
       --with-colons for a variant of this command.

       With the --check command the caller can test whether a key  exists  for  a  supplied  mail
       address.  The command returns success if a key is available.

       The  --create  command is used to send a request for publication in the Web Key Directory.
       The arguments are the fingerprint of the key and the user id to publish.  The output  from
       the  command is a properly formatted mail with all standard headers.  This mail can be fed
       to sendmail(8) or any other tool to actually send that mail.  If sendmail(8) is  installed
       the  option  --send  can  be  used  to directly send the created request.  If the provider
       request a 'mailbox-only' user id and no such user id is found, gpg-wks-client will try  an
       additional user id.

       The  --receive and --read commands are used to process confirmation mails as send from the
       service provider.  The former expects an encrypted MIME messages, the  latter  an  already
       decrypted  MIME  message.  The result of these commands are another mail which can be send
       in the same way as the mail created with --create.

       The command --install-key manually installs a key into a local directory (see  option  -C)
       reflecting  the  structure  of  a WKD.  The arguments are a file with the keyblock and the
       user-id to install.  If the first argument resembles a fingerprint the key is  taken  from
       the  current keyring; to force the use of a file, prefix the first argument with "./".  If
       no arguments are given the parameters are read from stdin; the expected format  are  lines
       with  the  fingerprint  and  the  mailbox  separated by a space.  The command --remove-key
       removes a key from that directory, its only argument is a user-id.

       The command --mirror is similar to --install-key but takes the  keys  from  the  the  LDAP
       server  configured  for  Dirmngr.   If  no  arguments  are given all keys and user ids are
       installed.  If arguments are given they are taken as domain  names  to  limit  the  to  be
       installed  keys.   The option --blacklist may be used to further limit the to be installed
       keys.

       The command --print-wkd-hash prints the WKD  user-id  identifiers  and  the  corresponding
       mailboxes from the user-ids given on the command line or via stdin (one user-id per line).

       The  command  --print-wkd-url prints the URLs used to fetch the key for the given user-ids
       from WKD.  The meanwhile preferred format with sub-domains is used here.

       gpg-wks-client is not commonly invoked directly and thus it is not installed  in  the  bin
       directory.   Here  is  an  example  how  it can be invoked manually to check for a Web Key
       Directory entry for ‘foo@example.org’:

         $(gpgconf --list-dirs libexecdir)/gpg-wks-client --check foo@example.net

OPTIONS

       gpg-wks-client understands these options:

       --send Directly send created mails using the sendmail command.  Requires  installation  of
              that command.

       --with-colons
              This option has currently only an effect on the --supported command.  If it is used
              all arguments on the command line are taken as domain  names  and  tested  for  WKD
              support.   The  output  format  is one line per domain with colon delimited fields.
              The currently specified fields are (future versions may specify additional fields):

              1 - domain
                     This is the domain name.  Although quoting is not required for valid  domain
                     names this field is specified to be quoted in standard C manner.

              2 - WKD
                     If the value is true the domain supports the Web Key Directory.

              3 - WKS
                     If  the  value  is  true the domain supports the Web Key Service protocol to
                     upload keys to the directory.

              4 - error-code
                     This may contain an gpg-error code to describe certain failures.  Use  ‘gpg-
                     error CODE’ to explain the code.

              5 - protocol-version
                     The minimum protocol version supported by the server.

              6 - auth-submit
                     The auth-submit flag from the policy file of the server.

              7 - mailbox-only
                     The mailbox-only flag from the policy file of the server.

       --output file
       -o     Write  the  created mail to file instead of stdout.  Note that the value - for file
              is the same as writing to stdout.

       --status-fd n
              Write special status strings to the file descriptor n.  This program  returns  only
              the  status  messages  SUCCESS  or FAILURE which are helpful when the caller uses a
              double fork approach and can't easily get the return code of the process.

       -C dir
       --directory dir
              Use dir as top  level  directory  for  the  commands  --mirror,  --install-key  and
              --remove-key.  The default is ‘openpgpkey’.

       --blacklist file
              This option is used to exclude certain mail addresses from a mirror operation.  The
              format of file is one mail address (just the addrspec, e.g.  "postel@isi.edu")  per
              line.  Empty lines and lines starting with a '#' are ignored.

       --verbose
              Enable extra informational output.

       --quiet
              Disable almost all informational output.

       --version
              Print version of the program and exit.

       --help Display a brief help page and exit.
