NAME

dirmngr-client - Tool to access the Dirmngr services

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test whether a certificate has been revoked -- either by being listed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 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1 The certificate has been revoked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.

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 protocol, 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.
