org.bouncycastle.crypto.agreement.jpake
Class JPAKERound1Payload

java.lang.Object
  extended by org.bouncycastle.crypto.agreement.jpake.JPAKERound1Payload
All Implemented Interfaces:
java.io.Serializable

public class JPAKERound1Payload
extends java.lang.Object
implements java.io.Serializable

The payload sent/received during the first round of a J-PAKE exchange.

Each JPAKEParticipant creates and sends an instance of this payload to the other JPAKEParticipant. The payload to send should be created via JPAKEParticipant.createRound1PayloadToSend().

Each JPAKEParticipant must also validate the payload received from the other JPAKEParticipant. The received payload should be validated via JPAKEParticipant.validateRound1PayloadReceived(JPAKERound1Payload).

This class is Serializable, so you can send it via Java serialization. However, no specific mechanism for sending this payload to the other participant is required. It is perfectly safe to decompose the fields of this payload, send those fields to the other participant in any format, and reconstruct the payload on the other side using JPAKERound1Payload(String, BigInteger, BigInteger, BigInteger[], BigInteger[]).
