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The dirmngr-client is a simple tool to contact a running dirmngr and test whether a certificate has been revoked --- either by being listed in the corresponding CRL or by running the OCSP protocol.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The certificate has been revoked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

--pem
Assume that the given certificate is in PEM (armored) format.

--ocsp
Do the check using the COSP protocol and ignore any CRLs.

--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. All CRL will be vfalidated 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.

--squid-mode
Run dirmngr-client in a mode suitable as a helper program for Squid's external_acl_type option.
