NAME

       dirmngr-client - CRL and OCSP daemon

SYNOPSIS

       dirmngr-client [options] [certfile|pattern]

DESCRIPTION

       The dirmngr-client is a simple tool to contact a running dirmngr and test whether a certificate has been revoked --- either by being listed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

       or

	 dirmngr-client <acert

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

RETURN VALUE

       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 tehre or teh 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       1      The certificate has been revoked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.

OPTIONS

       dirmngr-client may be called with the following options:

       --version
	      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 messages.

       -v

       --verbose
	      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.

       --force-default-responder
	      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.

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

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

       --load-crl
	      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.

       --lookup
	      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.

       --url

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

       --local

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

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