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.

  Throws:
    `InitialisationException` - if a fatal error occurs causing the Mule instance to shutdown
    `RecoverableException` - if an error occurs that can be recovered from

### getSecretKey

    protected abstract SecretKey getSecretKey()
                                       throws GeneralSecurityException

  Throws:
    `GeneralSecurityException`

### encrypt

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

  Throws:
    `CryptoFailureException`

### decrypt

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

  Throws:
    `CryptoFailureException`

### getAlgorithm
