java.lang.Object

org.mule.security.AbstractNamedEncryptionStrategy

org.mule.security.AbstractJCEEncryptionStrategy

org.mule.security.PasswordBasedEncryptionStrategy

All Implemented Interfaces:

EncryptionStrategy, Initialisable, NamedObject

public class PasswordBasedEncryptionStrategy
extends AbstractJCEEncryptionStrategy

Provides password-based encryption using JCE. Users must specify a password and optionally a salt and iteration count as well. The default algorithm is PBEWithMD5AndDES, but users can specify any valid algorithm supported by JCE.

Method Detail

initialise

public void initialise()
                throws InitialisationException

Description copied from interface: Initialisable

Method used to perform any initialisation work. If a fatal error occurs during initialisation an InitialisationException should be thrown, causing the Mule instance to shutdown. If the error is recoverable, say by retrying to connect, a RecoverableException should be thrown. There is no guarantee that by throwing a Recoverable exception that the Mule instance will not shut down.

Specified by:

initialise in interface Initialisable

Overrides:

initialise in class AbstractJCEEncryptionStrategy

Throws:

InitialisationException - if a fatal error occurs causing the Mule instance to shutdown

RecoverableException - if an error occurs that can be recovered from
