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test whether a certificate has been revoked --- either by being listed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 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:
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1 The certificate has been revoked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 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.
dirmngr-client may be called with the following options:
Print the program version and licensing information. Note that
you cannot abbreviate this command.
Print a usage message summarizing the most useful command-line
options. Note that you cannot abbreviate this command.
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 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.
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 valida-
tion 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.
The full documentation for this tool is maintained as a Texinfo manual.
If GnuPG and the info program are properly installed at your site, the
should give you access to the complete manual including a menu struc-
ture and an index.
