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 (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.
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 the DTLS connection. This is equivalent to calling g_dtls_connection_shutdown() to shut down both sides of the connection.
Asynchronously close the DTLS connection. See g_dtls_connection_close() for more information.
Finish an asynchronous TLS close operation. See g_dtls_connection_close() for more information.
Gets conn's certificate, as set by g_dtls_connection_set_certificate().
Gets the certificate database that conn uses to verify peer certificates. See g_dtls_connection_set_database().
Get the main Gtk struct
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.
Gets the name of the application-layer protocol negotiated during the handshake.
Gets conn's peer's certificate after the handshake has completed. (It is not set during the emission of accept-certificate.)
Gets the errors associated with validating conn's peer's certificate, after the handshake has completed. (It is not set during the emission of accept-certificate.)
Gets conn rehandshaking mode. See g_dtls_connection_set_rehandshake_mode() for details.
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.
Attempts a TLS handshake on conn.
Asynchronously performs a TLS handshake on conn. See g_dtls_connection_handshake() for more information.
Finish an asynchronous TLS handshake operation. See g_dtls_connection_handshake() for more information.
Sets the list of application-layer protocols to advertise that the caller is willing to speak on this connection. The Application-Layer Protocol Negotiation (ALPN) extension will be used to negotiate a compatible protocol with the peer; use g_dtls_connection_get_negotiated_protocol() to find the negotiated protocol after the handshake. Specifying NULL for the the value of protocols will disable ALPN negotiation.
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.
Sets the certificate database that is used to verify peer certificates. This is set to the default database by default. See g_tls_backend_get_default_database(). If set to NULL, then peer certificate validation will always set the G_TLS_CERTIFICATE_UNKNOWN_CA error (meaning accept-certificate will always be emitted on client-side connections, unless that bit is not set in validation-flags).
Set the object that will be used to interact with the user. It will be used for things like prompting the user for passwords.
Sets how conn behaves with respect to rehandshaking requests.
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).
Shut down part or all of a DTLS connection.
Asynchronously shut down part or all of the DTLS connection. See g_dtls_connection_shutdown() for more information.
Finish an asynchronous TLS shutdown operation. See g_dtls_connection_shutdown() for more information.
