Package org.bouncycastle.crypto.agreement.owl

Class OwlAuthenticationServerResponse

java.lang.Object

org.bouncycastle.crypto.agreement.owl.OwlAuthenticationServerResponse

public class OwlAuthenticationServerResponse
extends java.lang.Object

The payload sent by the server during the second pass of an Owl exchange.

Each OwlServer creates and sends an instance of this payload to the OwlClient. The payload to send should be created via OwlServer.authenticationServerResponse(OwlAuthenticationInitiate, OwlFinishRegistration).

Each OwlServer must also validate the payload received from the OwlClient which comes in the form of OwlAuthenticationInitiate. The OwlServer must retrieve the OwlFinishRegistration from wherever the server securely stored the initial login information. The received payload should be validated via the same function (in the same call).
