dirmngr-client - Tool to access the Dirmngr services

DIRMNGR-CLIENT(1) GNU Privacy Guard 2.1 DIRMNGR-CLIENT(1)

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The dirmngr-client is a simple tool to contact a running dirmngr and test whether a certificate has been revoked --- either by being listed in the corresponding CRL or by running the OCSP protocol.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The certificate has been revoked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