Description copied from interface: TlsServer

This method will be called (only) if the server included an extension of type "status_request" with empty "extension_data" in the extended server hello. See RFC 3546 3.6. Certificate Status Request. If a non-null CertificateStatus is returned, it is sent to the client as a handshake message of type "certificate_status".

Specified by:

getCertificateStatus in interface TlsServer

Returns:

A CertificateStatus to be sent to the client (or null for none).

Throws:

java.io.IOException

                             throws java.io.IOException

Description copied from interface: TlsServer

Called by the protocol handler to report the client certificate, only if TlsServer.getCertificateRequest() returned non-null. Note: this method is responsible for certificate verification and validation.

Specified by:

notifyClientCertificate in interface TlsServer

Parameters:

clientCertificate - the effective client certificate (may be an empty chain).

Throws:

java.io.IOException

getNewSessionTicket

public NewSessionTicket getNewSessionTicket()
                                     throws java.io.IOException

Description copied from interface: TlsServer

RFC 5077 3.3. NewSessionTicket Handshake Message.

This method will be called (only) if a NewSessionTicket extension was sent by the server. See RFC 5077 4. Recommended Ticket Construction for recommended format and protection.

Specified by:
