PROGRAM:

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certificate has been revoked --- either by being listed in the corresponding CRL or by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1 The certificate has been revoked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 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.
