Constructor Detail

### I2PDatagramDissector

    public I2PDatagramDissector()

  Crate a new I2P repliable datagram dissector.

Method Detail

### loadI2PDatagram

    public void loadI2PDatagram(byte[] dgram)
                         throws DataFormatException

  Load an I2P repliable datagram into the dissector.

  Parameters:
    `dgram` - I2P repliable datagram to be loader
  Throws:
    `DataFormatException` - If there's an error in the datagram format

### getPayload

    public byte[] getPayload()
                      throws I2PInvalidDatagramException

  Get the payload carried by an I2P repliable datagram (previously loaded with the loadI2PDatagram() method), verifying the datagram signature.

  Returns:
    A byte array containing the datagram payload
  Throws:
    `I2PInvalidDatagramException` - if the signature verification fails

### getSender

    public Destination getSender()
                          throws I2PInvalidDatagramException

  Get the sender of an I2P repliable datagram (previously loaded with the loadI2PDatagram() method), verifying the datagram signature.

  Returns:
    The Destination of the I2P repliable datagram sender
  Throws:
    `I2PInvalidDatagramException` - if the signature verification fails

### getHash

    public Hash getHash()
                 throws I2PInvalidDatagramException

  Extract the hash of the payload of an I2P repliable datagram (previously loaded with the loadI2PDatagram() method), verifying the datagram signature.

  Returns:
    The hash of the payload of the I2P repliable datagram
  Throws:
    `I2PInvalidDatagramException` - if the signature verification fails

### extractPayload

    public byte[] extractPayload()

  Extract the payload carried by an I2P repliable datagram (previously loaded with the loadI2PDatagram() method), without verifying the datagram signature.

  Returns:
    A byte array containing the datagram payload

### extractSender

    public Destination extractSender()

  Extract the sender of an I2P repliable datagram (previously loaded with the loadI2PDatagram() method), without verifying the datagram signature.

  Returns:
    The Destination of the I2P repliable datagram sender

### extractHash

    public Hash extractHash()

  Extract the hash of the payload of an I2P repliable datagram (previously loaded with the loadI2PDatagram() method), without verifying the datagram signature.

  Returns:
    The hash of the payload of the I2P repliable datagram

### verifySignature

    public void verifySignature()
                         throws I2PInvalidDatagramException

  Verify the signature of this datagram (previously loaded with the loadI2PDatagram() method)

  Throws:
    `I2PInvalidDatagramException` - if the signature is invalid
