The Certificate Status Tool is designed to provide certificate status information based on manually defined trust anchors as well as the EU Trusted Lists of Certification Service Providers (TSL). This status information includes OCSP and CRL-based revocation information. The tool also directly supports querying LDAP services for certificates. Some services are already configured by default (those used by the Austrian Citizen Card, in particular). Users can update the list of configured services using the provided Online Update functionality. In addition, the configuration can be extended locally. Version 3.2.0 introduces an interactive TSL explorer.
