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. For a client-side connection, peer_cert is the server's certificate, and the signal will only be emitted if the certificate was not acceptable according to conn's "validation_flags". If you would like the certificate to be accepted despite errors, return TRUE from the signal handler. Otherwise, if no handler accepts the certificate, the handshake will fail with G_TLS_ERROR_BAD_CERTIFICATE. For a server-side connection, peer_cert is the certificate presented by the client, if this was requested via the server's "authentication_mode". On the server side, the signal is always emitted when the client presents a certificate, and the certificate will only be accepted if a handler returns TRUE. Note that if this signal is emitted as part of asynchronous I/O in the main thread, then you should not attempt to interact with the user before returning from the signal handler. If you want to let the user decide whether or not to accept the certificate, you would have to return FALSE from the signal handler on the first attempt, and then after the connection attempt returns a G_TLS_ERROR_HANDSHAKE, you can interact with the user, and if the user decides to accept the certificate, remember that fact, create a new connection, and return TRUE from the signal handler the next time. If you are doing I/O in another thread, you do not need to worry about this, and can simply block in the signal handler until the UI thread returns an answer. TRUE to accept peer_cert (which will also immediately end the signal emission). FALSE to allow the signal emission to continue, which will cause the handshake to fail if no one else overrides it. Since 2.28
This sets the certificate that conn will present to its peer during the TLS handshake. For a GTlsServerConnection, it is mandatory to set this, and that will normally be done at construct time. For a GTlsClientConnection, this is optional. If a handshake fails with G_TLS_ERROR_CERTIFICATE_REQUIRED, that means that the server requires a certificate, and if you try connecting again, you should call this method first. You can call g_tls_client_connection_get_accepted_cas() on the failed connection to get a list of Certificate Authorities that the server will accept certificates from. (It is also possible that a server will allow the connection with or without a certificate; in that case, if you don't provide a certificate, you can tell that the server requested one by the fact that g_tls_client_connection_get_accepted_cas() will return non-NULL.) Since 2.28
Gets conn's certificate, as set by g_tls_connection_set_certificate(). Since 2.28
Gets conn's peer's certificate after the handshake has completed. (It is not set during the emission of "accept-certificate".) Since 2.28
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".) Since 2.28
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). In some protocols, the application will know whether or not the connection was closed cleanly based on application-level data (because the application-level data includes a length field, or is somehow self-delimiting); in this case, the close notify is redundant and sometimes omitted. (TLS 1.1 explicitly allows this; in TLS 1.0 it is technically an error, but often done anyway.) You can use g_tls_connection_set_require_close_notify() to tell conn to allow an "unannounced" connection close, in which case the close will show up as a 0-length read, as in a non-TLS GSocketConnection, and it is up to the application to check that the data has been fully received. Note that this only affects the behavior when the peer closes the connection; when the application calls g_io_stream_close() itself on conn, this will send a close notification regardless of the setting of this property. If you explicitly want to do an unclean close, you can close conn's "base-io-stream" rather than closing conn itself. Since 2.28
Tests whether or not conn expects a proper TLS close notification when the connection is closed. See g_tls_connection_set_require_close_notify() for details. Since 2.28
Sets how conn behaves with respect to rehandshaking requests. G_TLS_REHANDSHAKE_NEVER means that it will never agree to rehandshake after the initial handshake is complete. (For a client, this means it will refuse rehandshake requests from the server, and for a server, this means it will close the connection with an error if the client attempts to rehandshake.) G_TLS_REHANDSHAKE_SAFELY means that the connection will allow a rehandshake only if the other end of the connection supports the TLS renegotiation_info extension. This is the default behavior, but means that rehandshaking will not work against older implementations that do not support that extension. G_TLS_REHANDSHAKE_UNSAFELY means that the connection will allow rehandshaking even without the renegotiation_info extension. On the server side in particular, this is not recommended, since it leaves the server open to certain attacks. However, this mode is necessary if you need to allow renegotiation with older client software. Since 2.28
Gets conn rehandshaking mode. See g_tls_connection_set_rehandshake() for details. Since 2.28
Sets whether conn uses the system certificate database to verify peer certificates. This is TRUE by default. If set to FALSE, 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"). Since 2.28
Gets whether conn uses the system certificate database to verify peer certificates. See g_tls_connection_set_use_system_certdb(). Since 2.28
Attempts a TLS handshake on conn. On the client side, it is never necessary to call this method; although the connection needs to perform a handshake after connecting (or after sending a "STARTTLS"-type command) and may need to rehandshake later if the server requests it, GTlsConnection will handle this for you automatically when you try to send or receive data on the connection. However, you can call g_tls_connection_handshake() manually if you want to know for sure whether the initial handshake succeeded or failed (as opposed to just immediately trying to write to conn's output stream, in which case if it fails, it may not be possible to tell if it failed before or after completing the handshake). Likewise, on the server side, although a handshake is necessary at the beginning of the communication, you do not need to call this function explicitly unless you want clearer error reporting. However, you may call g_tls_connection_handshake() later on to renegotiate parameters (encryption methods, etc) with the client. "accept_certificate" may be emitted during the handshake. Since 2.28
Asynchronously performs a TLS handshake on conn. See g_tls_connection_handshake() for more information. Since 2.28
Finish an asynchronous TLS handshake operation. See g_tls_connection_handshake() for more information. Since 2.28
Used by GTlsConnection implementations to emit the "accept-certificate" signal. Since 2.28
Description GTlsServerConnection is the server-side subclass of GTlsConnection, representing a server-side TLS connection.
