dirmngr-client - Tool to access the Dirmngr services


   dirmngr-client [options] [certfile|pattern]


   The  dirmngr-client  is  a simple tool to contact a running dirmngr and
   test whether a certificate has been revoked --- either by being  listed
   in  the  corresponding  CRL  or  by  running  the OCSP protocol.  If no
   dirmngr is running, a new instances will be  started  but  this  is  in
   general not a good idea due to the huge performance overhead.

   The usual way to run this tool is either:

     dirmngr-client acert


     dirmngr-client <acert

   Where  acert  is  one  DER  encoded  (binary)  X.509 certificates to be


   dirmngr-client returns these values:

   0      The certificate under question is valid; i.e. there is  a  valid
          CRL  available  and  it  is not listed there or the OCSP request
          returned that that certificate is valid.

   1      The certificate has been revoked

   2 (and other values)
          There was  a  problem  checking  the  revocation  state  of  the
          certificate.   A  message  to  stderr  has  given  more detailed
          information.  Most likely this is due to a  missing  or  expired
          CRL or due to a network problem.


   dirmngr-client may be called with the following options:

          Print  the program version and licensing information.  Note that
          you cannot abbreviate this command.

   --help, -h
          Print a usage message summarizing the most  useful  command-line
          options.  Note that you cannot abbreviate this command.

   --quiet, -q
          Make  the  output  extra  brief by suppressing any informational


          Outputs additional information while running.  You can  increase
          the  verbosity  by  giving  several verbose commands to dirmngr,
          such as '-vv'.

   --pem  Assume that the given certificate is in PEM (armored) format.

   --ocsp Do the check using the OCSP protocol and ignore any CRLs.

          When checking using the OCSP  protocl,  force  the  use  of  the
          default  OCSP  responder.   That  is  not to use the Reponder as
          given by the certificate.

   --ping Check whether the dirmngr daemon is up and running.

          Put the given certificate into the cache of a  running  dirmngr.
          This is mainly useful for debugging.

          Validate   the   given   certificate  using  dirmngr's  internal
          validation code.  This is mainly useful for debugging.

          This command expects a list of filenames with  DER  encoded  CRL
          files.   With  the  option  --url  URLs are expected in place of
          filenames and they are loaded directly from the given  location.
          All CRLs will be validated and then loaded into dirmngr's cache.

          Take the remaining arguments and run a lookup command on each of
          them.  The results are Base-64 encoded outputs  (without  header
          lines).   This  may  be  used  to  retrieve  certificates from a
          server. However the output format is not  very  well  suited  if
          more than one certificate is returned.

   -u     Modify the lookup and load-crl commands to take an URL.

   -l     Let the lookup command only search the local cache.

          Run  dirmngr-client  in  a mode suitable as a helper program for
          Squid's external_acl_type option.
