DtlsConnectionIF

#GDtlsConnection is the base DTLS connection class type, which wraps a #GDatagramBased and provides DTLS encryption on top of it. Its subclasses, #GDtlsClientConnection and #GDtlsServerConnection, implement client-side and server-side DTLS, respectively.

For TLS support, see #GTlsConnection.

As DTLS is datagram based, #GDtlsConnection implements #GDatagramBased, presenting a datagram-socket-like API for the encrypted connection. This operates over a base datagram connection, which is also a #GDatagramBased (#GDtlsConnection:base-socket).

To close a DTLS connection, use g_dtls_connection_close().

Neither #GDtlsServerConnection or #GDtlsClientConnection set the peer address on their base #GDatagramBased if it is a #GSocket — it is up to the caller to do that if they wish. If they do not, and g_socket_close() is called on the base socket, the #GDtlsConnection will not raise a %G_IO_ERROR_NOT_CONNECTED error on further I/O.

Functions

addOnAcceptCertificate gulong addOnAcceptCertificate(bool delegate(TlsCertificate, GTlsCertificateFlags, DtlsConnectionIF) dlg, ConnectFlags connectFlags): Emitted during the TLS handshake after the peer certificate has been received. You can examine @peer_cert's certification path by calling g_tls_certificate_get_issuer() on it.
close bool close(Cancellable cancellable): Close the DTLS connection. This is equivalent to calling g_dtls_connection_shutdown() to shut down both sides of the connection.
closeAsync void closeAsync(int ioPriority, Cancellable cancellable, GAsyncReadyCallback callback, void* userData): Asynchronously close the DTLS connection. See g_dtls_connection_close() for more information.
closeFinish bool closeFinish(AsyncResultIF result): Finish an asynchronous TLS close operation. See g_dtls_connection_close() for more information.
emitAcceptCertificate bool emitAcceptCertificate(TlsCertificate peerCert, GTlsCertificateFlags errors): Used by #GDtlsConnection implementations to emit the #GDtlsConnection::accept-certificate signal.
getCertificate TlsCertificate getCertificate(): Gets @conn's certificate, as set by g_dtls_connection_set_certificate().
getDatabase TlsDatabase getDatabase(): Gets the certificate database that @conn uses to verify peer certificates. See g_dtls_connection_set_database().
getDtlsConnectionStruct GDtlsConnection* getDtlsConnectionStruct(bool transferOwnership): Get the main Gtk struct
getInteraction TlsInteraction getInteraction(): Get the object that will be used to interact with the user. It will be used for things like prompting the user for passwords. If %NULL is returned, then no user interaction will occur for this connection.
getPeerCertificate TlsCertificate getPeerCertificate(): Gets @conn's peer's certificate after the handshake has completed. (It is not set during the emission of #GDtlsConnection::accept-certificate.)
getPeerCertificateErrors GTlsCertificateFlags getPeerCertificateErrors(): Gets the errors associated with validating @conn's peer's certificate, after the handshake has completed. (It is not set during the emission of #GDtlsConnection::accept-certificate.)
getRehandshakeMode GTlsRehandshakeMode getRehandshakeMode(): Gets @conn rehandshaking mode. See g_dtls_connection_set_rehandshake_mode() for details.
getRequireCloseNotify bool getRequireCloseNotify(): Tests whether or not @conn expects a proper TLS close notification when the connection is closed. See g_dtls_connection_set_require_close_notify() for details.
getStruct void* getStruct(): the main Gtk struct as a void*
handshake bool handshake(Cancellable cancellable): Attempts a TLS handshake on @conn.
handshakeAsync void handshakeAsync(int ioPriority, Cancellable cancellable, GAsyncReadyCallback callback, void* userData): Asynchronously performs a TLS handshake on @conn. See g_dtls_connection_handshake() for more information.
handshakeFinish bool handshakeFinish(AsyncResultIF result): Finish an asynchronous TLS handshake operation. See g_dtls_connection_handshake() for more information.
setCertificate void setCertificate(TlsCertificate certificate): This sets the certificate that @conn will present to its peer during the TLS handshake. For a #GDtlsServerConnection, it is mandatory to set this, and that will normally be done at construct time.
setDatabase void setDatabase(TlsDatabase database): Sets the certificate database that is used to verify peer certificates. This is set to the default database by default. See g_dtls_backend_get_default_database(). If set to %NULL, then peer certificate validation will always set the %G_TLS_CERTIFICATE_UNKNOWN_CA error (meaning #GDtlsConnection::accept-certificate will always be emitted on client-side connections, unless that bit is not set in #GDtlsClientConnection:validation-flags).
setInteraction void setInteraction(TlsInteraction interaction): Set the object that will be used to interact with the user. It will be used for things like prompting the user for passwords.
setRehandshakeMode void setRehandshakeMode(GTlsRehandshakeMode mode): Sets how @conn behaves with respect to rehandshaking requests.
setRequireCloseNotify void setRequireCloseNotify(bool requireCloseNotify): Sets whether or not @conn expects a proper TLS close notification before the connection is closed. If this is %TRUE (the default), then @conn will expect to receive a TLS close notification from its peer before the connection is closed, and will return a %G_TLS_ERROR_EOF error if the connection is closed without proper notification (since this may indicate a network error, or man-in-the-middle attack).
shutdown bool shutdown(bool shutdownRead, bool shutdownWrite, Cancellable cancellable): Shut down part or all of a DTLS connection.
shutdownAsync void shutdownAsync(bool shutdownRead, bool shutdownWrite, int ioPriority, Cancellable cancellable, GAsyncReadyCallback callback, void* userData): Asynchronously shut down part or all of the DTLS connection. See g_dtls_connection_shutdown() for more information.
shutdownFinish bool shutdownFinish(AsyncResultIF result): Finish an asynchronous TLS shutdown operation. See g_dtls_connection_shutdown() for more information.
