Remarks

The AzureRelayReceiver class implements the listener role in the Azure Relay service. The class will connect to the server and listen for incoming connections. Once a connection is established data can be exchange freely in both directions allowing a flexible messaging environment.

Authenticating and Listening

Authentication to Azure Relay is performed using the Shared Access Key Name and Shared Access Key created from the Azure portal for the Relay. To begin listening for incoming connections set Listening to True.

When set to True the class will immediately attempt to make a connection to the Azure Relay Service and begin listening. The following properties are applicable when setting Listening:

To stop listening set Listening to False. To shutdown the server including existing connections call Shutdown.

Handling Connections

When a connection is made the ConnectionRequest event fires with information about the connecting client. From within this event the client connection may be accepted (default) or rejected.

If the client connection is accepted the ConnectionConnected and ConnectionReadyToSend events fire when the connection completes and is ready to send and receive data.

When data is received from the client the ConnectionDataIn event fires with the received data.

To send data to the client set AzureRelayConnectionDataToSend or call Send, SendFile, or SendText.

When the client disconnects the ConnectionDisconnected event fires. To initiate the client disconnection call Disconnect.

Handling HTTP Connections

Azure Relay also supports HTTP connections which follow a request/response model. When an HTTP request is received the HTTPRequest event fires with information about the request including the request body. Save the ConnectionId value obtained within HTTPRequest for use with SendHTTPResponse.

To send a HTTP response call SendHTTPResponse with the ConnectionId, status code and description, and any response day to be sent back to the client.

Forwarding Connections

The class supports forwarding incoming connection to a separate destination. This functionality allows AzureRelayReceiver to act as a proxy for incoming requests. When ForwardingHost and ForwardingPort are set anytime a connection is made the class will establish a separate connection to the ForwardingHost and forward all incoming traffic. Responses from the ForwardingHost are then automatically sent back over the connection.

When connection forwarding is used no special steps are needed to send or receive data. Data flows freely between the connected client and the ForwardingHost.

Note: Forwarding is not supported for HTTP requests.

Code Example (WebSockets)

Azurerelayreceiver listener = new Azurerelayreceiver(); listener.AccessKey = "9oKRDwjl0s440MlLUi4qHxDL34j1FS6K3t5TRoJ216c="; listener.AccessKeyName = "RootManageSharedAccessKey"; listener.NamespaceAddress = "myrelay.servicebus.windows.net"; listener.HybridConnection = "hc1"; listener.OnConnectionRequest += (s, e) => { Console.WriteLine("Connection Request From: " + e.RemoteAddress + ":" + e.RemotePort); e.Accept = true; }; listener.OnConnectionReadyToSend += (s, e) => { Console.WriteLine("Connection [" + e.ConnectionId + "] connected and ready to send and receive."); }; listener.OnConnectionDataIn += (s, e) => { Console.WriteLine("Received data from " + e.ConnectionId + ": " + e.Text); //echo the data back listener.SendText(e.ConnectionId, e.Text); Console.WriteLine("Echoed received data back"); }; listener.Listening = true; while (true) listener.DoEvents();

Code Example (HTTP)

Azurerelaylistener listener = new Azurerelaylistener(); listener.AccessKey = "9oKRDwjl0s440MlLUi4qHxDL34j1FS6K3t5TRoJ216c="; listener.AccessKeyName = "RootManageSharedAccessKey"; listener.NamespaceAddress = "myrelay.servicebus.windows.net"; listener.HybridConnection = "hc1"; listener.OnHTTPRequest += (s, e) => { Console.WriteLine("HTTP Request from " + e.RemoteAddress + ":" + e.RemotePort); Console.WriteLine("HTTP Method: " + e.RequestMethod); Console.WriteLine("HTTP Request: " + e.RequestData); myConnectionId = e.ConnectionId; }; //Send a response using the ConnectionId value from the HTTPRequest event listener.SendHTTPResponse(myConnectionId, 200, "OK", myResponseBody);

0

Remarks

This property specifies a timeout for the class.

If the AzureRelayConnectionTimeout property is set to 0, all operations return immediately, potentially failing with a WOULDBLOCK error if data cannot be sent immediately.

If AzureRelayConnectionTimeout is set to a positive value, data is sent in a blocking manner and the class will wait for the operation to complete before returning control. The class will handle any potential WOULDBLOCK errors internally and automatically retry the operation for a maximum of AzureRelayConnectionTimeout seconds.

The class will use DoEvents to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not freeze and remains responsive.

If Timeout expires, and the operation is not yet complete, the class fails with an error.

Note: By default, all timeouts are inactivity timeouts, that is, the timeout period is extended by Timeout seconds when any amount of data is successfully sent or received.

The default value for the AzureRelayConnectionTimeout property is 0(asynchronous operation).

The $connectionid parameter specifies the index of the item in the array. The size of the array is controlled by the AzureRelayConnectionCount property.

SendBytes Method (IPWorksMQ_AzureRelayReceiver Class)

This method sends binary data to the specified client.

Object Oriented Interface

public function doSendBytes($connectionid, $data);

Procedural Interface

ipworksmq_azurerelayreceiver_do_sendbytes($res, $connectionid, $data);

Remarks

This method sends binary data to the client identified by ConnectionId. To send text, use the SendText method instead.

When AzureRelayConnectionTimeout is set to 0, the class will behave asynchronously. If you are sending data to the remote host faster than it can process it, or faster than the network's bandwidth allows, the outgoing queue might fill up. When this happens, the operation fails with error 10035: "[10035] Operation would block" (WSAEWOULDBLOCK). You can check this error, and then try to send the data again. . The BytesSent property shows how many bytes were sent (if any). If 0 bytes were sent, then you can wait for the ReadyToSend event before attempting to send data again.

Note: The ReadyToSend event is not fired when part of the data is sent successfully.

SendFile Method (IPWorksMQ_AzureRelayReceiver Class)

This method sends the file to the remote host.

Object Oriented Interface

public function doSendFile($connectionid, $filename);

Procedural Interface

ipworksmq_azurerelayreceiver_do_sendfile($res, $connectionid, $filename);

Remarks

This method sends the file to the client specified by the ConnectionId.

SendHTTPResponse Method (IPWorksMQ_AzureRelayReceiver Class)

Send the HTTP response.

Object Oriented Interface

public function doSendHTTPResponse($connectionid, $statuscode, $statusdescription, $responsedata);

Procedural Interface

ipworksmq_azurerelayreceiver_do_sendhttpresponse($res, $connectionid, $statuscode, $statusdescription, $responsedata);

Remarks

This method sends an HTTP response to the HTTP request identified by ConnectionId.

The response status code and description, as well as the response body, are sent to the client using this method. The ConnectionId value should be obtained from the HTTPRequest event.

StatusCode is the three digit HTTP status code to return, for instance 200.

StatusDescription is the text corresponding to the StatusCode. For instance OK.

ResponseBody specifies the body to be sent back to the client (if any).

Code Example (HTTP)

Azurerelaylistener listener = new Azurerelaylistener(); listener.AccessKey = "9oKRDwjl0s440MlLUi4qHxDL34j1FS6K3t5TRoJ216c="; listener.AccessKeyName = "RootManageSharedAccessKey"; listener.NamespaceAddress = "myrelay.servicebus.windows.net"; listener.HybridConnection = "hc1"; listener.OnHTTPRequest += (s, e) => { Console.WriteLine("HTTP Request from " + e.RemoteAddress + ":" + e.RemotePort); Console.WriteLine("HTTP Method: " + e.RequestMethod); Console.WriteLine("HTTP Request: " + e.RequestData); myConnectionId = e.ConnectionId; }; //Send a response using the ConnectionId value from the HTTPRequest event listener.SendHTTPResponse(myConnectionId, 200, "OK", myResponseBody);

SendText Method (IPWorksMQ_AzureRelayReceiver Class)

This method sends text data to the client.

Object Oriented Interface

public function doSendText($connectionid, $text);

Procedural Interface

ipworksmq_azurerelayreceiver_do_sendtext($res, $connectionid, $text);

Remarks

This method sends text to the client identified by ConnectionId. To send binary data, use the SendBytes method instead.

When AzureRelayConnectionTimeout is set to 0, the class will behave asynchronously. If you are sending data to the remote host faster than it can process it, or faster than the network's bandwidth allows, the outgoing queue might fill up. When this happens, the operation fails with error 10035: "[10035] Operation would block" (WSAEWOULDBLOCK). You can check this error, and then try to send the data again. . The BytesSent property shows how many bytes were sent (if any). If 0 bytes were sent, then you can wait for the ReadyToSend event before attempting to send data again.

Note: The ReadyToSend event is not fired when part of the data is sent successfully.

This method sends text to the client identified by ConnectionId. Data sent with this method will always be treated as text data regardless of the value of AzureRelayConnectionDataFormat. The class will UTF-8 encode the supplied text.

Shutdown Method (IPWorksMQ_AzureRelayReceiver Class)

This method shuts down the server.

Object Oriented Interface

public function doShutdown();

Procedural Interface

ipworksmq_azurerelayreceiver_do_shutdown($res);

Remarks

Parameter List

 'connectionid'
'dataformat'
'text'
'eom'

Remarks

The DataIn event provides the data received from the client identified by the ConnectionId parameter.

The incoming data are provided through the Text parameter.

The DataFormat parameter identifies the encoding (if any) of the data. Possible value are as follows:

0 If LineMode is disabled, a value of 0 indicates a continuation packet. If LineMode is enabled, the value will always be 0, regardless of packet type.
1 The data are UTF-8 encoded.
2 The data are binary and have no encoding.

The EOM parameter stands for End of Message. By default, the class will fire the DataIn event as data are received. Larger messages will be fragmented and will cause the event to fire multiple times. When EOM is True within the event, this indicates the current fragment is also the final fragment of the message. The class may also be configured to buffer the message internally until the complete message is received. To enable this, set BufferMessage to True.

The EOL parameter stands for End of Line. When LineMode is False, EOL will always be False. When LineMode is True, EOL will be True if the DataIn event fired because an EOL was received and will be False if the DataIn event fired because MaxLineLength was reached.

ConnectionDisconnected Event (IPWorksMQ_AzureRelayReceiver Class)

Fired when a WebSocket connection is disconnected.

Parameter Descriptions

ConnectionId contains an identifier generated by the class to identify each connection. This identifier is unique to this connection.

RendezvousAddress holds the rendezvous URL to which the connection specific websocket connection may be made. This is for information only, no action needs to be taken based on this value. For instance: wss://g2-prod-by3-003-sb.servicebus.windows.net/$hc/hc1?sb-hc-action=request&sb-hc-id=e1df5efe-0988-450c-9512-f9f1d91b39a0_G2

Id holds the Id of the connection. If an Id was specified by the client it is present here, otherwise the Azure Relay service generates a value. For instance: 2d4acb89-7d15-4aeb-bcd5-66e031580a90_G21_G1.

RequestHeaders contains a JSON object containing the HTTP headers supplied to the Azure Relay service by the sender. Note that authorization values used to authenticate to the Azure Relay service, as well as all headers defined in RFC 7230 with the exception of Via are also stripped. For instance headers such as Content-Length are stripped by the relay and are not present in this value. For instance:

"requestHeaders": {
	"Accept-Encoding": "gzip, deflate",
	"Host": "nstest.servicebus.windows.net",
	"User-Agent": "IPWorks HTTP Component - www.nsoftware.com",

RemotePort contains the port used by the remote host to establish the connection.

RequestData holds the body of the HTTP request (if any).

Log Event (IPWorksMQ_AzureRelayReceiver Class)

This event fires once for each log message.

Object Oriented Interface

public function fireLog($param);

Procedural Interface

ipworksmq_azurerelayreceiver_register_callback($res, 13, array($this, 'fireLog'));

Parameter List

 'connectionid'
'loglevel'
'message'
'logtype'

Remarks

This event fires once for each log message generated by the class. The verbosity is controlled by the LogLevel setting.

LogLevel indicates the level of message. Possible values are as follows:

0 (None) No events are logged.
1 (Info - default) Informational events are logged.
2 (Verbose) Detailed data are logged.
3 (Debug) Debug data are logged.

The value 1 (Info) logs basic information including the URL, HTTP version, and connection status details.

The value 2 (Verbose) logs additional information about the initial HTTP request.

The value 3 (Debug) logs additional debug information (if available).

Message is the log entry.

LogType identifies the type of log entry. Possible values are as follows:

  • "Info"
  • "Error"
  • "Verbose"
  • "Debug"
ConnectionId specifies the Id of the connection to which the log applies.

Redirect Event (IPWorksMQ_AzureRelayReceiver Class)

'certissuer'
'status'
'accept'

Remarks

During this event, the client can decide whether or not to continue with the connection process. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether or not to continue.

When Accept is False, Status shows why the verification failed (otherwise, Status contains the string OK). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.

SSLStatus Event (IPWorksMQ_AzureRelayReceiver Class)

Config Settings (AzureRelayReceiver Class)

The class accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

AzureRelayReceiver Config Settings

AccessToken:   Returns an access token for use outside of the components.

This setting returns an access token suitable for use in the HTTP Authorization header of a request. This is useful when a separate HTTP client is used to make a HTTP request to the relay service. The value returned by this setting can be set directly as the value for the Authorization header.

The value will be in the format:

SharedAccessSignature sr=sb%3a%2f%2fnstest.servicebus.windows.net%2fhc1&sig=a2EjYWw%2fDlg%2bPcNb%2fC7%2fxBbM11JjfgdO6ZVsQRm18Gg%3d&se=1555368805&skn=RootManageSharedAccessKey

AutoRenewThreshold:   The threshold in seconds after which the token is renewed.

This setting specifies a threshold used by the class to determine when to automatically renew the listener token while connected to the Azure Relay service.

When connected to the Azure Relay a Shared Access Token grants access to the service. After TokenValidity seconds this token will expire. To prevent disconnection the class will automatically renew the token once the remaining seconds on the life of the token is below this threshold.

For instance if AutoRenewThreshold is set to 100 (seconds). Once the class token is valid for only 99 seconds it will be automatically renewed.

The default value is 300 (seconds).

AzureRelayKeepAliveTime:   The inactivity period in seconds before a ping packet is sent to keep the connection alive.

This setting specifies the inactivity period in seconds after which a ping packet is sent on the control channel to keep the connection to the Azure Relay Service alive.

The default value is 0 (disabled).

Note: This functionality is not yet supported

DiagnosticId:   A diagnostic id used to enable end-to-end tracing.

This setting optionally specifies a diagnostic Id that is associated with the control connection established to the Azure Relay server when Listening is set to True. If set, this allows end-to-end tracing of the connection for diagnostic purposes. If specified this should be a GUID. For instance f479cece-a32d-4caf-aed3-6dcc3b7b661e.

LogLevel:   The level of detail that is logged.

This setting controls the level of detail that is logged through the Log event. Possible values are:

0 (None) No events are logged.
1 (Info - default) Informational events are logged.
2 (Verbose) Detailed data is logged.
3 (Debug) Debug data is logged.

The value 1 (Info) logs basic information about the connection and connecting clients.

The value 2 (Verbose) logs detailed information about each connection and the control connection.

The value 3 (Debug) logs additional debug information (if any).

TokenValidity:   The validity time in seconds of the access token.

This setting specifies the validity time of the access token to create when authenticating. The default value is 3600 seconds.

WebSocketServer Config Settings

BufferMessage:   Indicates whether or not the entire message is buffered before firing the DataIn event.

When receiving large messages the DataIn, this event may fire multiple times to provide data as it is received in each message fragment. When BufferMessage is set to True, the class will internally buffer the message as it is received until it is complete before firing the DataIn event. The default value is False.

DisconnectStatusCode:   Specifies the status code when closing a connection.

When the Disconnect method is called, the class will send the status code specified here. By default, the value is 1,000, which indicates a normal closure. Any other value represents an error condition. You may set any value you wish, but the protocol defines the following common values.

1000 (default) Normal closure.
1001 The resource is going away. For instance, the server is shutting down or a browser is navigating away from the page.
1002 A protocol error occurred.
1003 Unexpected data were received (e.g., an endpoint that accepts only text data could send this if binary data are received).
1007 Invalid payload data were received (e.g., an endpoint that receives non-UTF-8 data in a text message could send this).
1008 A generic code that indicates the endpoint received a message that violates its policy.
1009 A message that was too large was received.
1010 A required extension could not be negotiated.
1011 An unexpected error occurred.

DisconnectStatusDescription:   Specifies the message associated with the disconnect status code.

This configuration setting may be used to provide a textual description of the status code sent when closing the connection. This configuration setting works in conjunction with DisconnectStatusCode. For any of the standard codes listed in DisconnectStatusCode, the class will use a default description that may be overridden with this setting. For any nonstandard codes that are not listed, this setting should be set or no description will be sent.

MaxFrameSize:   Specifies the maximum size of the outgoing message in bytes before fragmentation occurs.

This configuration setting specifies the maximum size of the outgoing message in bytes before fragmentation will occur. When a message that is larger than MaxFrameSize is sent, it will be broken into fragments with the maximum size specified here. The default value is 131072 (128K).

When a message is fragmented, the receiving side may check the EOM parameter of the DataIn event to determine when the message is complete.

Note: When Timeout is set to 0 messages that are fragmented are always sent as individual smaller messages and EOM will always be True in the DataIn event on the receiving side.

MessageLength[ConnectionId]:   The length of the message (in bytes) when sending asynchronously.

This setting specifies the length of messages being sent when operating asynchronously.

When DefaultTimeout is set to 0 the class operates asynchronously and by default all data sent when Send is called or AzureRelayConnectionDataToSend is set is considered a complete message. Each packet leaving the class has the End-of-Message flag set.

To send messages which may be fragmented, set MessageLength to the length of the message (in bytes) that is being sent. When set the class will consider the next MessageLength bytes sent as part of a single message and only the last packet will set the End-of-Message flag.

This setting is helpful when data is organized into messages and the receiving side expected the End-of-Message flag to signal the end of a message.

Note: This setting is only applicable when DefaultTimeout is set to 0. When DefaultTimeout is set to a positive value the message data may be passed in its entirety to AzureRelayConnectionDataToSend or Send and will be automatically handled as needed by the class.

WaitForCloseResponse:   Determines whether or not the class will forcibly close a connection.

When true (default) the class will wait for a response from the client when closing the connection. When this setting is set to false, the class will forcibly close the connection without waiting for a response from the client.

TCPServer Config Settings

AllowedClients:   A comma-separated list of host names or IP addresses that can access the class.

This configuration setting defines a comma-separated list of host names or IPv4 addresses that may access the class. The wildcard character "*" is supported. The default value is "*" and all connections are accepted.

When a client connects, the client's address is checked against the list defined here. If there is no match, the ConnectionRequest event fires with an Accept value set to false. If no action is taken within the ConnectionRequest event, the client will be disconnected.

BindExclusively:   Whether or not the component considers a local port reserved for exclusive use.

If this is true (default), the component will bind to the local port with the ExclusiveAddressUse option set, meaning that nothing else can bind to the same port. Also the component will not be able to bind to local ports that are already in use by some other instance, and attempts to do so will result in failure.

BlockedClients:   A comma-separated list of host names or IP addresses that cannot access the class.

This configuration setting defines a comma-separated list of host names or IPv4 addresses that cannot access the class.The default value is "" and all connections are accepted.

When a client connects, the client's address is checked against the list defined here. If there is a match, the ConnectionRequest event fires with an Accept value set to false. If no action is taken within the ConnectionRequest event, the client will not be connected.

ConnectionUID:   The unique connectionId for a connection.

Connection Ids may be reused as clients connect and disconnect. Querying ConnectionUID will return a unique identifier for that connection Id. If the specified connection Id does not exist, then ConnectionUID will return 0. For example:

Connection5UID = obj.config("ConnectionUID[5]")

DefaultConnectionTimeout:   The inactivity timeout applied to the SSL handshake.

This configuration setting specifies the inactivity (in seconds) to apply to incoming Secure Sockets Layer (SSL) connections. When set to a positive value, if the other end is unresponsive for the specified number of seconds, the connection will timeout. This is not applicable to the entire handshake. It is applicable only to the inactivity of the connecting client during the handshake if a response is expected and none is received within the timeout window. The default value is 0, and no connection-specific timeout is applied.

Note: This is applicable only to incoming SSL connections. This should be set only if there is a specific reason to do so.

InBufferSize:   The size in bytes of the incoming queue of the socket.

This is the size of an internal queue in the Transmission Control Protocol (TCP)/IP stack. You can increase or decrease its size depending on the amount of data that you will be receiving. Increasing the value of the InBufferSize setting can provide significant improvements in performance in some cases.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the class is activated, the InBufferSize reverts to its defined size. The same thing will happen if you attempt to make it too large or too small.

InBufferSize is shared among incoming connections. When the property is set, the corresponding value is set for incoming connections as they are accepted. Existing connections are not modified.

KeepAliveInterval:   The retry interval, in milliseconds, to be used when a TCP keep-alive packet is sent and no response is received.

A TCP keep-alive packet will be sent after a period of inactivity, as defined by KeepAliveTime. If no acknowledgment is received from the remote host, the keep-alive packet will be sent again. This setting specifies the interval at which the successive keep-alive packets are sent in milliseconds. If this value is not specified here, the system default is 1 second. This setting is applicable to all connections.

Note: This value is not applicable in macOS.

KeepAliveRetryCount:   The number of keep-alive packets to be sent before the remotehost is considered disconnected.

A TCP keep-alive packet will be sent after a period of inactivity, as defined by KeepAliveTime. If no acknowledgment is received from the remote host, the keep-alive packet will be sent again. This setting specifies the number of times that the keep-alive packets will be sent again before the remote host is considered disconnected. If this value is not specified here, the system default is 9.

Note: This configuration setting is available only in the Unix platform, and it is not supported in macOS or FreeBSD.

KeepAliveTime:   The inactivity time in milliseconds before a TCP keep-alive packet is sent.

By default, the operating system will determine the time a connection is idle before a TCP keep-alive packet is sent. If this value is not specified here, the system default is 2 hours. In many cases, a shorter interval is more useful. Set this value to the desired interval in milliseconds. This setting is applicable to all connections.

MaxConnections:   The maximum number of connections available.

This is the maximum number of connections available. This property must be set before Listening is set to true, and once set, it can no longer be changed for the current instance of the class. The maximum value for this setting is 100,000 connections. Use this setting with caution. Extremely large values may affect performance. The default value is 1000.

Note: Unix/Linux operating systems limit the number of simultaneous connections to 1024.

MaxReadTime:   The maximum time spent reading data from each connection.

This setting specifies the maximum time in milliseconds that the class will spend reading data from a particular connection before servicing other connections. When a single client is sending data to the class at a high rate this setting is used to ensure that other connections are serviced in a timely manner. Specifying a positive value prevents a single client from monopolizing the class's resources. The special value of 0 indicates no limit and is generally not recommended.

The default value is 50 (milliseconds).

OutBufferSize:   The size in bytes of the outgoing queue of the socket.

This is the size of an internal queue in the TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be sending. Increasing the value of the OutBufferSize setting can provide significant improvements in performance in some cases.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the class is activated the OutBufferSize reverts to its defined size. The same thing will happen if you attempt to make it too large or too small.

OutBufferSize is shared among incoming connections. When the property is set, the corresponding value is set for incoming connections as they are accepted. Existing connections are not modified.

TcpNoDelay:   Whether or not to delay when sending packets.

When set to True, the socket will send all data that are ready to send at once. When set to False, the socket will send smaller buffered packets of data at small intervals. This is known as the Nagle algorithm.

By default, this configuration setting is set to False.

UseIOCP:   Whether to use the completion port I/O model.

The default value is false. When set to true, the class will use an I/O Completion Port (IOCP) to manage operations on sockets. A single completion port allows the asynchronous notification of network events on an entire group of sockets. This property must be set before Listening is set to true.

Nothing else is required to begin accepting IOCP connections. One major benefit to using this model is that there will be no thread blocked waiting for a request to complete. The system notifies the process through an Asynchronous Procedure Call (APC) once the device driver finishes servicing the I/O request. IOCP allows a single I/O worker thread handle multiple clients' input/output "fairly".

Note: When set to true, this setting will automatically set UseWindowsMessages to false.

UseIPv6:   Whether to use IPv6.

When set to 0 (default), the class will use IPv4 exclusively. When set to 1, the class will use IPv6 exclusively. When set to 2, the class will listen for both IPv4 and IPv6 connections. If IPv6 is not available on the system, only IPv4 will be used. The default value is 0. Possible values are as follows:

0 IPv4 Only
1 IPv6 Only
2 IPv6 and IPv4
UseWindowsMessages:   Whether to use the WSAAsyncSelect I/O model.

The default value is true, and the class will receive a Windows message-based notification of network events. Turning on Windows message notifications allows the application to get connect, send, receive, and socket closure network event notifications on a socket. This property must be set before Listening is set to true.

Nothing else is required to begin accepting connections using the Windows message queue. In high-traffic environments, messages will be discarded if the queue is full. Additionally, because a single window procedure will service all events on thousands of sockets, the Windows message queue is not scalable from a performance perspective.

If this setting is set to false, the class will instead use the Winsock select model instead.

SSL Config Settings

LogSSLPackets:   Controls whether SSL packets are logged when using the internal security API.

When SSLProvider is set to Internal, this configuration setting controls whether Secure Sockets Layer (SSL) packets should be logged. By default, this configuration setting is False, as it is useful only for debugging purposes.

When enabled, SSL packet logs are output using the SSLStatus event, which will fire each time an SSL packet is sent or received.

Enabling this configuration setting has no effect if SSLProvider is set to Platform.

OpenSSLCADir:   The path to a directory containing CA certificates.

This functionality is available only when the provider is OpenSSL.

The path set by this property should point to a directory containing CA certificates in PEM format. The files each contain one CA certificate. The files are looked up by the CA subject name hash value, which must hence be available. If more than one CA certificate with the same name hash value exist, the extension must be different (e.g., 9d66eef0.0, 9d66eef0.1). OpenSSL recommends the use of the c_rehash utility to create the necessary links. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.

OpenSSLCAFile:   Name of the file containing the list of CA's trusted by your application.

This functionality is available only when the provider is OpenSSL.

The file set by this property should contain a list of CA certificates in PEM format. The file can contain several CA certificates identified by the following sequences:

-----BEGIN CERTIFICATE-----

... (CA certificate in base64 encoding) ...

-----END CERTIFICATE-----

Before, between, and after the certificate text is allowed, which can be used, for example, for descriptions of the certificates. Refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.

OpenSSLCipherList:   A string that controls the ciphers to be used by SSL.

This functionality is available only when the provider is OpenSSL.

The format of this string is described in the OpenSSL man page ciphers(1) section "CIPHER LIST FORMAT". Please refer to it for details. The default string "DEFAULT" is determined at compile time and is normally equivalent to "ALL:!ADH:RC4+RSA:+SSLv2:@STRENGTH".

OpenSSLPrngSeedData:   The data to seed the pseudo random number generator (PRNG).

This functionality is available only when the provider is OpenSSL.

By default, OpenSSL uses the device file "/dev/urandom" to seed the PRNG, and setting OpenSSLPrngSeedData is not required. If set, the string specified is used to seed the PRNG.

ReuseSSLSession:   Determines if the SSL session is reused.

If set to True, the class will reuse the context if and only if the following criteria are met:

  • The target host name is the same.
  • The system cache entry has not expired (default timeout is 10 hours).
  • The application process that calls the function is the same.
  • The logon session is the same.
  • The instance of the class is the same.

SSLCACertFilePaths:   The paths to CA certificate files on Unix/Linux.

This configuration setting specifies the paths on disk to CA certificate files on Unix/Linux.

The value is formatted as a list of paths separated by semicolons. The class will check for the existence of each file in the order specified. When a file is found, the CA certificates within the file will be loaded and used to determine the validity of server or client certificates.

The default value is as follows:

/etc/ssl/ca-bundle.pem;/etc/pki/tls/certs/ca-bundle.crt;/etc/ssl/certs/ca-certificates.crt;/etc/pki/tls/cacert.pem

SSLCACerts:   A newline separated list of CA certificates to be included when performing an SSL handshake.

When SSLProvider is set to Internal, this configuration setting specifies one or more CA certificates to be included with the SSLCert property. Some servers or clients require the entire chain, including CA certificates, to be presented when performing SSL authentication. The value of this configuration setting is a newline-separated (CR/LF) list of certificates. For instance:

-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw
... Intermediate Cert ...
eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w
F0I1XhM+pKj7FjDr+XNj
-----END CERTIFICATE-----
\r \n
-----BEGIN CERTIFICATE-----
MIIEFjCCAv6gAwIBAgIQetu1SMxpnENAnnOz1P+PtTANBgkqhkiG9w0BAQUFADBp
... Root Cert ...
d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA
-----END CERTIFICATE-----

SSLCheckCRL:   Whether to check the Certificate Revocation List for the server certificate.

This configuration setting specifies whether the class will check the Certificate Revocation List (CRL) specified by the server certificate. If set to 1 or 2, the class will first obtain the list of CRL URLs from the server certificate's CRL distribution points extension. The class will then make HTTP requests to each CRL endpoint to check the validity of the server's certificate. If the certificate has been revoked or any other issues are found during validation the class fails with an error.

When set to 0 (default), the CRL check will not be performed by the class. When set to 1, it will attempt to perform the CRL check, but it will continue without an error if the server's certificate does not support CRL. When set to 2, it will perform the CRL check and will throw an error if CRL is not supported.

This configuration setting is supported only in the Java, C#, and C++ editions. In the C++ edition, it is supported only on Windows operating systems.

SSLCheckOCSP:   Whether to use OCSP to check the status of the server certificate.

This configuration setting specifies whether the class will use OCSP to check the validity of the server certificate. If set to 1 or 2, the class will first obtain the Online Certificate Status Protocol (OCSP) URL from the server certificate's OCSP extension. The class will then locate the issuing certificate and make an HTTP request to the OCSP endpoint to check the validity of the server's certificate. If the certificate has been revoked or any other issues are found during validation, the class fails with an error.

When set to 0 (default), the class will not perform an OCSP check. When set to 1, it will attempt to perform the OCSP check, but it will continue without an error if the server's certificate does not support OCSP. When set to 2, it will perform the OCSP check and will throw an error if OCSP is not supported.

This configuration setting is supported only in the Java, C#, and C++ editions. In the C++ edition, it is supported only on Windows operating systems.

SSLCipherStrength:   The minimum cipher strength used for bulk encryption.

This minimum cipher strength is largely dependent on the security modules installed on the system. If the cipher strength specified is not supported, an error will be returned when connections are initiated.

Note: This configuration setting contains the minimum cipher strength requested from the security library. The actual cipher strength used for the connection is shown by the SSLStatus event.

Use this configuration setting with caution. Requesting a lower cipher strength than necessary could potentially cause serious security vulnerabilities in your application.

When the provider is OpenSSL, SSLCipherStrength is currently not supported. This functionality is instead made available through the OpenSSLCipherList configuration setting.

SSLClientCACerts:   A newline separated list of CA certificates to use during SSL client certificate validation.

This configuration setting is only applicable to server components (e.g., TCPServer) see SSLServerCACerts for client components (e.g., TCPClient). This setting can be used to optionally specify one or more CA certificates to be used when verifying the client certificate that is presented by the client during the SSL handshake when SSLAuthenticateClients is enabled. When verifying the client's certificate, the certificates trusted by the system will be used as part of the verification process. If the client's CA certificates are not installed to the trusted system store, they may be specified here so they are included when performing the verification process. This configuration setting should be set only if the client's CA certificates are not already trusted on the system and cannot be installed to the trusted system store.

The value of this configuration setting is a newline-separated (CR/LF) list of certificates. For instance:

-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw
... Intermediate Cert ...
eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w
F0I1XhM+pKj7FjDr+XNj
-----END CERTIFICATE-----
\r \n
-----BEGIN CERTIFICATE-----

... Root Cert ...
d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA
-----END CERTIFICATE-----

SSLEnabledCipherSuites:   The cipher suite to be used in an SSL negotiation.

This configuration setting enables the cipher suites to be used in SSL negotiation.

By default, the enabled cipher suites will include all available ciphers ("*").

The special value "*" means that the class will pick all of the supported cipher suites. If SSLEnabledCipherSuites is set to any other value, only the specified cipher suites will be considered.

Multiple cipher suites are separated by semicolons.

Example values when SSLProvider is set to Platform include the following: obj.config("SSLEnabledCipherSuites=*"); obj.config("SSLEnabledCipherSuites=CALG_AES_256"); obj.config("SSLEnabledCipherSuites=CALG_AES_256;CALG_3DES"); Possible values when SSLProvider is set to Platform include the following:

When TLS 1.3 is negotiated (see SSLEnabledProtocols), only the following cipher suites are supported:

  • TLS_AES_256_GCM_SHA384
  • TLS_CHACHA20_POLY1305_SHA256
  • TLS_AES_128_GCM_SHA256

SSLEnabledCipherSuites is used together with SSLCipherStrength.

SSLEnabledProtocols:   Used to enable/disable the supported security protocols.

This configuration setting is used to enable or disable the supported security protocols.

Not all supported protocols are enabled by default. The default value is 4032 for client components, and 3072 for server components. To specify a combination of enabled protocol versions set this config to the binary OR of one or more of the following values:

TLS1.312288 (Hex 3000)
TLS1.23072 (Hex C00) (Default - Client and Server)
TLS1.1768 (Hex 300) (Default - Client)
TLS1 192 (Hex C0) (Default - Client)
SSL3 48 (Hex 30)
SSL2 12 (Hex 0C)

Note that only TLS 1.2 is enabled for server components that accept incoming connections. This adheres to industry standards to ensure a secure connection. Client components enable TLS 1.0, TLS 1.1, and TLS 1.2 by default and will negotiate the highest mutually supported version when connecting to a server, which should be TLS 1.2 in most cases.

SSLEnabledProtocols: Transport Layer Security (TLS) 1.3 Notes:

By default when TLS 1.3 is enabled, the class will use the internal TLS implementation when the SSLProvider is set to Automatic for all editions.

In editions that are designed to run on Windows, SSLProvider can be set to Platform to use the platform implementation instead of the internal implementation. When configured in this manner, please note that the platform provider is supported only on Windows 11/Windows Server 2022 and up. The default internal provider is available on all platforms and is not restricted to any specific OS version.

If set to 1 (Platform provider), please be aware of the following notes:

  • The platform provider is available only on Windows 11/Windows Server 2022 and up.
  • SSLEnabledCipherSuites and other similar SSL configuration settings are not supported.
  • If SSLEnabledProtocols includes both TLS 1.3 and TLS 1.2, these restrictions are still applicable even if TLS 1.2 is negotiated. Enabling TLS 1.3 with the platform provider changes the implementation used for all TLS versions.

SSLEnabledProtocols: SSL2 and SSL3 Notes:

SSL 2.0 and 3.0 are not supported by the class when the SSLProvider is set to internal. To use SSL 2.0 or SSL 3.0, the platform security API must have the protocols enabled and SSLProvider needs to be set to platform.

SSLEnableRenegotiation:   Whether the renegotiation_info SSL extension is supported.

This configuration setting specifies whether the renegotiation_info SSL extension will be used in the request when using the internal security API. This configuration setting is false by default, but it can be set to true to enable the extension.

This configuration setting is applicable only when SSLProvider is set to Internal.

SSLIncludeCertChain:   Whether the entire certificate chain is included in the SSLServerAuthentication event.

This configuration setting specifies whether the Encoded parameter of the SSLServerAuthentication event contains the full certificate chain. By default this value is False and only the leaf certificate will be present in the Encoded parameter of the SSLServerAuthentication event.

If set to True, all certificates returned by the server will be present in the Encoded parameter of the SSLServerAuthentication event. This includes the leaf certificate, any intermediate certificate, and the root certificate.

SSLKeyLogFile:   The location of a file where per-session secrets are written for debugging purposes.

This configuration setting optionally specifies the full path to a file on disk where per-session secrets are stored for debugging purposes.

When set, the class will save the session secrets in the same format as the SSLKEYLOGFILE environment variable functionality used by most major browsers and tools, such as Chrome, Firefox, and cURL. This file can then be used in tools such as Wireshark to decrypt TLS traffic for debugging purposes. When writing to this file, the class will only append, it will not overwrite previous values.

Note: This configuration setting is applicable only when SSLProvider is set to Internal.

SSLNegotiatedCipher:   Returns the negotiated cipher suite.

This configuration setting returns the cipher suite negotiated during the SSL handshake.

Note: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedCipher[connId]");

SSLNegotiatedCipherStrength:   Returns the negotiated cipher suite strength.

This configuration setting returns the strength of the cipher suite negotiated during the SSL handshake.

Note: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedCipherStrength[connId]");

SSLNegotiatedCipherSuite:   Returns the negotiated cipher suite.

This configuration setting returns the cipher suite negotiated during the SSL handshake represented as a single string.

Note: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedCipherSuite[connId]");

SSLNegotiatedKeyExchange:   Returns the negotiated key exchange algorithm.

This configuration setting returns the key exchange algorithm negotiated during the SSL handshake.

Note: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedKeyExchange[connId]");

SSLNegotiatedKeyExchangeStrength:   Returns the negotiated key exchange algorithm strength.

This configuration setting returns the strength of the key exchange algorithm negotiated during the SSL handshake.

Note: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedKeyExchangeStrength[connId]");

SSLNegotiatedVersion:   Returns the negotiated protocol version.

This configuration setting returns the protocol version negotiated during the SSL handshake.

Note: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedVersion[connId]");

SSLSecurityFlags:   Flags that control certificate verification.

The following flags are defined (specified in hexadecimal notation). They can be ORed together to exclude multiple conditions:

0x00000001Ignore time validity status of certificate.
0x00000002Ignore time validity status of CTL.
0x00000004Ignore non-nested certificate times.
0x00000010Allow unknown certificate authority.
0x00000020Ignore wrong certificate usage.
0x00000100Ignore unknown certificate revocation status.
0x00000200Ignore unknown CTL signer revocation status.
0x00000400Ignore unknown certificate authority revocation status.
0x00000800Ignore unknown root revocation status.
0x00008000Allow test root certificate.
0x00004000Trust test root certificate.
0x80000000Ignore non-matching CN (certificate CN non-matching server name).

This functionality is currently not available when the provider is OpenSSL.

SSLServerCACerts:   A newline separated list of CA certificates to use during SSL server certificate validation.

This configuration setting is only used by client components (e.g., TCPClient) see SSLClientCACerts for server components (e.g., TCPServer). This configuration setting can be used to optionally specify one or more CA certificates to be used when connecting to the server and verifying the server certificate. When verifying the server's certificate, the certificates trusted by the system will be used as part of the verification process. If the server's CA certificates are not installed to the trusted system store, they may be specified here so they are included when performing the verification process. This configuration setting should be set only if the server's CA certificates are not already trusted on the system and cannot be installed to the trusted system store.

The value of this configuration setting is a newline-separated (CR/LF) list of certificates. For instance:

-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw

-----END CERTIFICATE-----

TLS12SignatureAlgorithms:   Defines the allowed TLS 1.2 signature algorithms when SSLProvider is set to Internal.

This configuration setting specifies the allowed server certificate signature algorithms when SSLProvider is set to Internal and SSLEnabledProtocols is set to allow TLS 1.2.

When specified the class will verify that the server certificate signature algorithm is among the values specified in this configuration setting. If the server certificate signature algorithm is unsupported, the class fails with an error.

The format of this value is a comma-separated list of hash-signature combinations. For instance: component.SSLProvider = TCPClientSSLProviders.sslpInternal; component.Config("SSLEnabledProtocols=3072"); //TLS 1.2 component.Config("TLS12SignatureAlgorithms=sha256-rsa,sha256-dsa,sha1-rsa,sha1-dsa"); The default value for this configuration setting is sha512-ecdsa,sha512-rsa,sha512-dsa,sha384-ecdsa,sha384-rsa,sha384-dsa,sha256-ecdsa,sha256-rsa,sha256-dsa,sha224-ecdsa,sha224-rsa,sha224-dsa,sha1-ecdsa,sha1-rsa,sha1-dsa.

To not restrict the server's certificate signature algorithm, specify an empty string as the value for this configuration setting, which will cause the signature_algorithms TLS 1.2 extension to not be sent.

TLS12SupportedGroups:   The supported groups for ECC.

This configuration setting specifies a comma-separated list of named groups used in TLS 1.2 for ECC.

The default value is ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1.

When using TLS 1.2 and SSLProvider is set to Internal, the values refer to the supported groups for ECC. The following values are supported:

  • "ecdhe_secp256r1" (default)
  • "ecdhe_secp384r1" (default)
  • "ecdhe_secp521r1" (default)

TLS13KeyShareGroups:   The groups for which to pregenerate key shares.

This configuration setting specifies a comma-separated list of named groups used in TLS 1.3 for key exchange. The groups specified here will have key share data pregenerated locally before establishing a connection. This can prevent an additional roundtrip during the handshake if the group is supported by the server.

The default value is set to balance common supported groups and the computational resources required to generate key shares. As a result, only some groups are included by default in this configuration setting.

Note: All supported groups can always be used during the handshake even if not listed here, but if a group is used that is not present in this list, it will incur an additional roundtrip and time to generate the key share for that group.

In most cases, this configuration setting does not need to be modified. This should be modified only if there is a specific reason to do so.

The default value is ecdhe_x25519,ecdhe_secp256r1,ecdhe_secp384r1,ffdhe_2048,ffdhe_3072

The values are ordered from most preferred to least preferred. The following values are supported:

  • "ecdhe_x25519" (default)
  • "ecdhe_x448"
  • "ecdhe_secp256r1" (default)
  • "ecdhe_secp384r1" (default)
  • "ecdhe_secp521r1"
  • "ffdhe_2048" (default)
  • "ffdhe_3072" (default)
  • "ffdhe_4096"
  • "ffdhe_6144"
  • "ffdhe_8192"

TLS13SignatureAlgorithms:   The allowed certificate signature algorithms.

This configuration setting holds a comma-separated list of allowed signature algorithms. Possible values include the following:

  • "ed25519" (default)
  • "ed448" (default)
  • "ecdsa_secp256r1_sha256" (default)
  • "ecdsa_secp384r1_sha384" (default)
  • "ecdsa_secp521r1_sha512" (default)
  • "rsa_pkcs1_sha256" (default)
  • "rsa_pkcs1_sha384" (default)
  • "rsa_pkcs1_sha512" (default)
  • "rsa_pss_sha256" (default)
  • "rsa_pss_sha384" (default)
  • "rsa_pss_sha512" (default)
The default value is rsa_pss_sha256,rsa_pss_sha384,rsa_pss_sha512,rsa_pkcs1_sha256,rsa_pkcs1_sha384,rsa_pkcs1_sha512,ecdsa_secp256r1_sha256,ecdsa_secp384r1_sha384,ecdsa_secp521r1_sha512,ed25519,ed448. This configuration setting is applicable only when SSLEnabledProtocols includes TLS 1.3.
TLS13SupportedGroups:   The supported groups for (EC)DHE key exchange.

This configuration setting specifies a comma-separated list of named groups used in TLS 1.3 for key exchange. This configuration setting should be modified only if there is a specific reason to do so.

The default value is ecdhe_x25519,ecdhe_x448,ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1,ffdhe_2048,ffdhe_3072,ffdhe_4096,ffdhe_6144,ffdhe_8192

The values are ordered from most preferred to least preferred. The following values are supported:

  • "ecdhe_x25519" (default)
  • "ecdhe_x448" (default)
  • "ecdhe_secp256r1" (default)
  • "ecdhe_secp384r1" (default)
  • "ecdhe_secp521r1" (default)
  • "ffdhe_2048" (default)
  • "ffdhe_3072" (default)
  • "ffdhe_4096" (default)
  • "ffdhe_6144" (default)
  • "ffdhe_8192" (default)
