All Implemented Interfaces:

DTLSMessage

public final class PSKServerKeyExchange
extends ServerKeyExchange

The key exchange message sent when using the preshared key key exchange algorithm. To help the client in selecting which identity to use, the server can provide a "PSK identity hint" in the ServerKeyExchange message. If no hint is provided, the ServerKeyExchange message is omitted. See ServerKeyExchange for the message format.

PSKServerKeyExchange

public PSKServerKeyExchange(PskPublicInformation hint,
                    InetSocketAddress peerAddress)

Method Detail

getMessageLength

public int getMessageLength()

Description copied from class: HandshakeMessage

Must be implemented by each subclass. The length is given in bytes and only includes the length of the subclass' specific fields (not the handshake message header).

Specified by:

getMessageLength in class HandshakeMessage

Returns:

the length of the message in bytes.

toString

public String toString()

Overrides:

toString in class HandshakeMessage

fragmentToByteArray

public byte[] fragmentToByteArray()

Description copied from class: HandshakeMessage

The serialization of the handshake body (without the handshake header). Must be implemented by each subclass. Except the ClientHello, the fragments are considered to be not modified. If a modification is required, call HandshakeMessage.fragmentChanged().

Specified by:

fragmentToByteArray in class HandshakeMessage

Returns:

the raw byte representation of the handshake body.

fromReader

public static HandshakeMessage fromReader(org.eclipse.californium.elements.util.DatagramReader reader,
                          InetSocketAddress peerAddress)

getHint

public PskPublicInformation getHint()
