public Class JPAKERound1Payload

Class Inheritance

extends Object

Imports

java.math.BigInteger, org.bouncycastle.util.Arrays

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).
