public Class ECJPAKERound2Payload

extends Object

Class Inheritance

Imports

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

Each ECJPAKEParticipant creates and sends an instance of this payload to the other ECJPAKEParticipant. The payload to send should be created via ECJPAKEParticipant#createRound2PayloadToSend()

Field Summary
