getEarlyKeyShareGroups back to summary

getEarlyKeyShareGroups	back to summary
public Vector<E> getEarlyKeyShareGroups() If this client is offering TLS 1.3 or higher, this method may be called to determine for which groups a key share should be included in the initial ClientHello. Groups that were not included in the supported_groups extension (by `getClientExtensions()` will be ignored. The protocol will then add a suitable key_share extension to the ClientHello extensions. Returns:Vector<E> a `Vector` of `named group` values, possibly empty or null.

public Vector<E> getEarlyKeyShareGroups()

If this client is offering TLS 1.3 or higher, this method may be called to determine for which groups a key share should be included in the initial ClientHello. Groups that were not included in the supported_groups extension (by getClientExtensions() will be ignored. The protocol will then add a suitable key_share extension to the ClientHello extensions.

Returns:Vector<E>: a Vector of named group values, possibly empty or null.

getExternalPSKs	back to summary
public Vector<E> getExternalPSKs() Return the `external PSKs` to offer in the ClientHello. Note that this will only be called when TLS 1.3 or higher is amongst the offered protocol versions. Returns:Vector<E> a `Vector` of `TlsPSKExternal` instances, or null if none should be offered.

public Vector<E> getExternalPSKs()

Return the external PSKs to offer in the ClientHello. Note that this will only be called when TLS 1.3 or higher is amongst the offered protocol versions.

Returns:Vector<E>: a Vector of TlsPSKExternal instances, or null if none should be offered.

getSessionToResume	back to summary
public TlsSession getSessionToResume() Return the session this client wants to resume, if any. Note that the peer's certificate chain for the session (if any) may need to be periodically revalidated. Returns:TlsSession A `TlsSession` representing the resumable session to be used for this connection, or null to use a new session. See Also `SessionParameters#getPeerCertificate()`

public TlsSession getSessionToResume()

Return the session this client wants to resume, if any. Note that the peer's certificate chain for the session (if any) may need to be periodically revalidated.

Returns:TlsSession: A TlsSession representing the resumable session to be used for this connection, or null to use a new session.

public void notifyNewSessionTicket(NewSessionTicket newSessionTicket) throws IOException RFC 5077 3.3. NewSessionTicket Handshake Message This method will be called (only) when a NewSessionTicket handshake message is received. The ticket is opaque to the client and clients MUST NOT examine the ticket under the assumption that it complies with e.g. RFC 5077 4. Recommended Ticket Construction. Parameters newSessionTicket:NewSessionTicket The ticket.

RFC 5077 3.3. NewSessionTicket Handshake Message

This method will be called (only) when a NewSessionTicket handshake message is received. The ticket is opaque to the client and clients MUST NOT examine the ticket under the assumption that it complies with e.g. RFC 5077 4. Recommended Ticket Construction.

Parameters

newSessionTicket:NewSessionTicket: The ticket.

notifySessionID	back to summary
public void notifySessionID(byte[] sessionID) Notifies the client of the session_id sent in the ServerHello. See Also `TlsContext#getSession()`

public void notifySessionID(byte[] sessionID)

Notifies the client of the session_id sent in the ServerHello.

See Also: TlsContext#getSession()

notifySessionToResume back to summary

notifySessionToResume	back to summary
public void notifySessionToResume(TlsSession session) Notifies the client of the session that will be offered in ClientHello for resumption, if any. This will be either the session returned from `getSessionToResume()` or null if that session was unusable. Note the actual negotiated session_id is notified by `notifySessionID(byte[])`. Parameters session:TlsSession The `TlsSession` representing the resumable session to be offered for this connection, or null if there is none. See Also `notifySessionID(byte[])`

public void notifySessionToResume(TlsSession session)

Notifies the client of the session that will be offered in ClientHello for resumption, if any. This will be either the session returned from getSessionToResume() or null if that session was unusable.

Note

the actual negotiated session_id is notified by notifySessionID(byte[]).

Parameters

session:TlsSession: The TlsSession representing the resumable session to be offered for this connection, or null if there is none.

notifySessionID(byte[])

processServerExtensions	back to summary
public void processServerExtensions(Hashtable<K, V> serverExtensions) throws IOException The TlsClientProtocol implementation validates that any server extensions received correspond to client extensions sent. If further processing of the server extensions is needed, it can be done in this callback. Note This is not called for session resumption handshakes. Parameters serverExtensions:Hashtable<K, V> (Integer -> byte[])
