using the @option{-object tls-creds} argument.
The @option{tls-creds} parameter obsoletes the @option{tls},
@option{x509}, and @option{x509verify} options, and as such
it is not permitted to set both new and old type options at
the same time.
@item tls
Require that client use TLS when communicating with the VNC server. This
uses anonymous TLS credentials so is susceptible to a man-in-the-middle
attack. It is recommended that this option be combined with either the
@option{x509} or @option{x509verify} options.
This option is now deprecated in favor of using the @option{tls-creds}
argument.
@item x509=@var{/path/to/certificate/dir}
Valid if @option{tls} is specified. Require that x509 credentials are used
for negotiating the TLS session. The server will send its x509 certificate
to the client. It is recommended that a password be set on the VNC server
to provide authentication of the client when this is used. The path following
this option specifies where the x509 certificates are to be loaded from.
See the @ref{vnc_security} section for details on generating certificates.
This option is now deprecated in favour of using the @option{tls-creds}
argument.
@item x509verify=@var{/path/to/certificate/dir}
Valid if @option{tls} is specified. Require that x509 credentials are used
for negotiating the TLS session. The server will send its x509 certificate
to the client, and request that the client send its own x509 certificate.
The server will validate the client's certificate against the CA certificate,
and reject clients when validation fails. If the certificate authority is
trusted, this is a sufficient authentication mechanism. You may still wish
to set a password on the VNC server as a second authentication layer. The
path following this option specifies where the x509 certificates are to
be loaded from. See the @ref{vnc_security} section for details on generating
certificates.
