Class SecretKeyEncryptionStrategy

java.lang.Object

org.mule.security.AbstractNamedEncryptionStrategy

org.mule.security.AbstractJCEEncryptionStrategy

org.mule.security.SecretKeyEncryptionStrategy

All Implemented Interfaces:

EncryptionStrategy, Initialisable

public class SecretKeyEncryptionStrategy
extends AbstractJCEEncryptionStrategy

SecretKey based encryption using JCE. Users must specify a key as an array of bytes. This can be set directly on the strategy or a keyFactory can be specified. A keyFactory is an implementation of SecretKeyFactory and must return a byte array. The default algorthm used by this strategy is Blowfish, 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
