NAMEdirmngr-client - Tool to access the Dirmngr services
SYNOPSISdirmngr-client [options] [certfile|pattern]
DESCRIPTIONThe dirmngr-client is a simple tool to contact a running dirmngr and test whether a certificate has been revoked --- either by being listed in the corresponding CRL or by running the OCSP protocol.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:
Where acert is one DER encoded (binary) X.509 certificates to be tested.
RETURN VALUEdirmngr-client returns these values:
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.
The certificate has been revoked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.
dirmngr-client may be called with the following options:
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.
Outputs additional information while running.
You can increase the verbosity by giving several
verbose commands to dirmngr, such as aq-vvaq.
Assume that the given certificate is in PEM (armored) format.
Do the check using the OCSP protocol and ignore any CRLs.
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.
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 validation 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.
Modify the lookup and load-crl commands to take an URL.
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.
