$program $version, a non-interactive utility for publishing CRL's.
Usage: $program [OPTIONS] crl_file
$program is a non-interactive utility for publishing CRL's. It takes a single
argument pointing to the CRL file which should be published. The CRL file should
be provided either in DER or PEM encoding.
The script is written to support several types of publishers. Currently
supported publishers are:
- scp - Publishes to a remote server using public-key authentication through
SSH's scp command.
- archiver - Archives CRLs to a local directory. This publisher will output
the CRLs to a specific directory using the filename pattern
'issuerdn_fulldateutc_crlnumber.format' where issuerdn is replaced by the
issuer DN of the CRL, fulldateutc is replaced with last update date of CRL
in format YYYY-MM-DD-HH:MM:SS:TZ (e.g. 2013-01-01-00:00:00:+00:00),
crlnumber is replaced with the CRL number in decimal format, and format is
replaced by the format of the CRL file (PEM for OpenSSL-style
base64-encoded CRLs, DER for binary CRLs).
Publishing options are kept within configuration files. Configuration files
should be placed in the explicitly set configurtion directory (set with the -c
option), or one of the following default locations:
- /etc/crlpublisher/
- ~/.crlpublisher/
Configuration files must end with a .conf extension. All other files will be
ignored. Each configuraiton file should contain information for a single
publisher matching a single issuer DN.
Common configuration options
issuerDn (mandatory) - Specifies the distinguished name of the issuer of CRL
which should be matched for the particular configuration.
publisher (mandatory) - Type of publisher this configuration refers to.
Configuration options for 'scp' publisher:
remoteHost (mandatory) - Remote IP or resolvable hostname/FQDN of the target
server to which the CRL will be published.
remoteLocation (mandatory) - Full path on the remote server to the directory
location to which the CRL will be published.
remoteUser (optional) - Name of the remote user which will be used for
logging-in. Default is the user executing the script.
privateKey (optional) - Path to the private key which should be used for
logging-in onto remote server. Default is ~/.ssh/id_rsa.
remotePort (optional) - Remote port that should be used for connecting to
the SSH server on remote host. Default is to use port 22.
Configuration options for 'archiver' publisher:
acrhiveDir (mandatory) - Directory where the CRLs will be archived.
$program accepts the following options:
-c dir Explicit configuration directory from which the publisher
configuration files should be read.
-v show script version and licensing information
-h show usage help
