onAcceptCertificate
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
#GDtlsClientConnection: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.
GLib guarantees that if certificate verification fails, this signal
will be emitted with at least one error will be set in @errors, but
it does not guarantee that all possible errors will be set.
Accordingly, you may not safely decide to ignore any particular
type of error. For example, it would be incorrect to ignore
%G_TLS_CERTIFICATE_EXPIRED if you want to allow expired
certificates, because this could potentially be the only error flag
set even if other problems exist with the certificate.
For a server-side connection, @peer_cert is the certificate
presented by the client, if this was requested via the server's
#GDtlsServerConnection: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_BAD_CERTIFICATE, 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.- Parameters:
peer_cert- the peer's #GTlsCertificateerrors- the problems with @peer_cert.- Returns:
- %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.
