  Constant Field Values

Constructor Detail

### AuthenticatedEntry

    public AuthenticatedEntry(java.lang.String mac,
                              int macLen,
                              Properties properties)

Method Detail

### decode

    public static AuthenticatedEntry decode(java.io.DataInputStream in)
                                     throws java.io.IOException

    `java.io.IOException`

### authenticate

    public void authenticate(byte[] key)
                      throws java.io.IOException,
                             java.security.InvalidKeyException

  Computes the mac over this envelope's data. This method must be called before this entry in encoded.

  Parameters:
    `key` - The key to authenticate with.
  Throws:
    `java.io.IOException` - If encoding fails.
    `java.security.InvalidKeyException` - If the supplied key is bad.

### verify

    public void verify(byte[] key)
                throws java.security.InvalidKeyException

  Verifies this entry's payload. This method will unmask this entry, thus it must be called before accessing its contents.

  Parameters:
    `key` - The key to use to authenticate.
  Throws:
    `java.security.InvalidKeyException` - If the given key is improper.

### encodePayload

    protected void encodePayload()
                          throws java.io.IOException

  Description copied from class: `Entry`
  This method is called of subclasses when the payload data needs to be created.

  Overrides:
    `encodePayload` in class `EnvelopeEntry`
  Throws:
    `java.io.IOException` - If an encoding error occurs.
