@Deprecated
    public VirtualHostBuilder tlsAllowUnsafeCiphers() {
        return tlsAllowUnsafeCiphers(true);
    }
Allows the bad cipher suites listed in
<a href="https://datatracker.ietf.org/doc/html/rfc7540#appendix-A">RFC7540</a> for TLS handshake.

<p>Note that enabling this option increases the security risk of your connection.
Use it only when you must communicate with a legacy system that does not support
secure cipher suites.
See <a href="https://datatracker.ietf.org/doc/html/rfc7540#section-9.2.2">Section 9.2.2, RFC7540</a> for
more information. This option is disabled by default.

@deprecated It's not recommended to enable this option. Use it only when you have no other way to
            communicate with an insecure peer than this.
