Class FileBasedCredentialStore

java.lang.Object

org.apache.ambari.server.security.encryption.AbstractCredentialStore

org.apache.ambari.server.security.encryption.FileBasedCredentialStore

All Implemented Interfaces:

CredentialStore

public class FileBasedCredentialStore
extends AbstractCredentialStore

FileBasedCredentialStore is a CredentialStore implementation that creates and manages a JCEKS (Java Cryptography Extension KeyStore) file on disk. The key store and its contents are encrypted using the key from the supplied MasterKeyService.

Most of the work for this implementation is handled by the AbstractCredentialStore. This class handles the details of the storage location and associated input and output streams.
