Custom CipherSuite

[sertunc]

Hello, how can i set custom cipher suite like

`public static KestrelServerOptions ListenSera(this KestrelServerOptions options, SeraSettings seraSettings)
{
options.Listen(IPAddress.Parse(seraSettings.ListenIP), seraSettings.Port, listenOptions =>
{
listenOptions.UseConnectionLimits(veraSettings.ConnectionLimit);
listenOptions.UseHttps(adapterOptions =>
{
adapterOptions.OnAuthenticate = (context, authenticationOptions) =>
{
authenticationOptions.CipherSuitesPolicy = new CipherSuitesPolicy(new[]
{
TlsCipherSuite.TLS_DHE_RSA_WITH_AES_256_CBC_SHA256,
TlsCipherSuite.TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA,
});
};
adapterOptions.SslProtocols = SslProtocols.Tls12;
adapterOptions.CheckCertificateRevocation = false;
adapterOptions.HandshakeTimeout = TimeSpan.FromSeconds(veraSettings.TlsHandshakeTimeout);
adapterOptions.ClientCertificateMode = ClientCertificateMode.AllowCertificate;
adapterOptions.ServerCertificate =
new X509Certificate2(Path.Combine("certs", veraSettings.ServerCertificateFilename),
veraSettings.ServerCertificatePassword);
adapterOptions.AllowAnyClientCertificate();
});
listenOptions.UseConnectionLogging();
listenOptions.UseConnectionHandler();
});

    return options;
}

}`
