java.lang.Objectjava.security.cert.CertStoreSpi
eu.emi.security.authn.x509.helpers.crl.PlainCRLStoreSpi
public class PlainCRLStoreSpi
Handles an in-memory CRL store.
CRLs may be provided as URLs or local files. If the CRL is provided as a local file (i.e. is not an absolute URL) then it can contain wildcard characters ('*', '?'). In case of wildcard locations, the actual file list is regenerated on each update.
All CRLs are loaded and parsed to establish CA->CRL mapping. This mapping is updated after the updateInterval time is passed.
Faulty CRL locations together with the respective errors can be obtained by using a listener.
It is possible to pass more then one location of CRLs of the same CA.
The class is implemented in an asynchronous mode: CRLs are updated on regular intervals (or only once on startup). The CRL searching is independent of the updates and never blocks to download, read or parse a CRL.
CRLs downloaded from a remote URL (http or ftp) can be cached on a local disk. If the update task can not download the CRL which was previously cached on disk, then the version from disk is returned.
This class is thread safe.
