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

Throws:

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

getSecretKey

protected abstract SecretKey getSecretKey()
                                   throws GeneralSecurityException

Throws:

GeneralSecurityException

encrypt

public byte[] encrypt(byte[] data,
                      Object info)
               throws CryptoFailureException

Specified by:

encrypt in interface UMOEncryptionStrategy

Throws:

decrypt

public byte[] decrypt(byte[] data,
                      Object info)
               throws CryptoFailureException
