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The dirmngr-client is a simple tool to contact a running dirmngr and test whether a certificate has been revoked — either by being listed in the corresponding CRL or by running the OCSP protocol.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The certificate has been revoked |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.
