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test whether a certificate has been revoked --- either by being listed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 dirm-
ngr 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1 The certificate has been revoked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 cer-
tificate. A message to stderr has given more detailed informa-
tion. 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 valida-
tion 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.
