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dirmngr and test whether a certificate has been revoked --- either by being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
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:
or
Where acert is one DER encoded (binary) X.509 certificates
to be tested.
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- The certificate has been revoked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.
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.
