Reloadable File-backed KeyStore ------------------------------- Key: ELY-118 URL: https://issues.jboss.org/browse/ELY-118 Project: WildFly Elytron Issue Type: Enhancement Components: KeyStores Reporter: David Lloyd Assignee: Darran Lofthouse Fix For: 1.1.0.CR2 File-backed keystores can generically be made reloadable. This can be done by creating a KeyStore wrapper which contains an {{AtomicReference<KeyStore>}}. The wrapper also has a file name reference, and will initialize itself from that file. It would use an NIO.2 file watcher to monitor the file for changes; when the file is changed, the watcher attempts to re-load the file into a new KeyStore instance (using cached protection parameters). If successful, the new KeyStore replaces the old one atomically, providing atomic and clean real-time update capability.
