Note that this property is ignored if the Port property is set to a non-zero value, in which case the server always aims to listen on that fixed port.

ServerCertificates Property (WebSocketServer Class)

The server's TLS certificates.

Syntax

public CertificateList getServerCertificates();


public void setServerCertificates(CertificateList serverCertificates);

Remarks

Use this property to provide a list of TLS certificates for the server endpoint.

A TLS endpoint needs a certificate to be able to accept TLS connections. At least one of the certificates in the collection - the endpoint certificate - must have a private key associated with it.

The collection may include more than one endpoint certificate, and more than one chain. A typical usage scenario is to include two chains (ECDSA and RSA), to cater for clients with different cipher suite preferences.

  public String hashAlgorithm;
  public String pars;
  public String data;
  public String signedData;
}

Remarks

Assign a handler to this event if you need to delegate a low-level signing operation to an external, remote, or custom signing engine. Depending on the settings, the handler will receive a hashed or unhashed value to be signed.

The event handler must pass the value of Data to the signer, obtain the signature, and pass it back to the class via the SignedData parameter.

OperationId provides a comment about the operation and its origin. It depends on the exact class being used, and may be empty. HashAlgorithm specifies the hash algorithm being used for the operation, and Pars contains algorithm-dependent parameters.

The class uses base16 (hex) encoding for the Data, SignedData, and Pars parameters. If your signing engine uses a different input and output encoding, you may need to decode and/or encode the data before and/or after the signing.

A sample MD5 hash encoded in base16: a0dee2a0382afbb09120ffa7ccd8a152 - lower case base16 A0DEE2A0382AFBB09120FFA7CCD8A152 - upper case base16

A sample event handler that uses the .NET RSACryptoServiceProvider class may look like the following: signer.OnExternalSign += (s, e) => { var cert = new X509Certificate2("cert.pfx", "", X509KeyStorageFlags.Exportable); var key = (RSACryptoServiceProvider)cert.PrivateKey; var dataToSign = e.Data.FromBase16String(); var signedData = key.SignHash(dataToSign, "2.16.840.1.101.3.4.2.1"); e.SignedData = signedData.ToBase16String(); };

  public String URI;
  public boolean handled;
}

Remarks

The class fires this event to notify the application about a GET request received from the client.

ConnectionID indicates the connection that sent the request and URI suggests the requested resource.

Set Handled to true to indicate that your application's code will take care of the request. The application does it by providing the necessary details via SetResponseStatus, SetResponseHeader, SetResponseFile or SetResponseString methods. If the returned value of Handled is false, the server will try to take care of the request automatically by searching for the requested resource in DocumentRoot.
