SMPP Component

Properties Methods Events Config Settings Errors

The SMPP Component implements a lightweight message transmission interface using the Short Message Peer-to-Peer protocol, most known for its use in cellular text messaging.

Syntax

nsoftware.IPWorks.SMPP

Remarks

The SMPP component supports both plaintext and Secure Sockets Layer/Transport Layer Security (SSL/TLS) connections. When connecting over Secure Sockets Layer/Transport Layer Security (SSL/TLS) the SSLServerAuthentication event allows you to check the server identity and other security attributes. The SSLStatus event provides information about the SSL handshake. Additional SSL-related settings are also supported through the Config method.

The Smpp Component will bind as a transceiver, and thus it can send and receive messages from the server. Additionally, it can send single and multirecipient messages and also can upload data.

Using Smpp is quite easy. First, simply set the SMPPServer, SMPPPort, and, if needed, the SMPPVersion properties. Second, a single call to the Connect method with a specified user Id and password will connect the component.

Transmitting messages is just as easy. You can manipulate the Recipients collection directly, or just use AddRecipient method to add recipients one at a time to the recipient list. After all recipients have been added, a single call to the SendMessage method will transmit the specified message. If the send is successful, the method will set and return the value of the MessageId property. Otherwise, an Error event will fire for each unsuccessful message destination.

The Smpp Component supports message and data transmission, as well as auxiliary operations, such as CheckMessageStatus and ReplaceMessage. All nonimplemented features of the protocol are supported through the SendCommand method and PITrail event. Because of the nature of the protocol, all methods and operations are implemented synchronously.

Connected Property (SMPP Component)

This property indicates whether the component is connected.

public bool Connected { get; }

Public ReadOnly Property Connected As Boolean

Default Value

False

Remarks

This property indicates whether the component is connected to the remote host. Use the Connect and Disconnect methods to manage the connection.

This property is read-only and not available at design time.

Firewall Property (SMPP Component)

A set of properties related to firewall access.

Syntax

C#
VB.NET

public Firewall Firewall { get; set; }

Public Property Firewall As Firewall

Remarks

This is a Firewall-type property, which contains fields describing the firewall through which the component will attempt to connect.

Please refer to the Firewall type for a complete list of fields.

Idle Property (SMPP Component)

The current status of the component.

Syntax

C#
VB.NET

public bool Idle { get; }

Public ReadOnly Property Idle As Boolean

Default Value

True

Remarks

This property will be False if the component is currently busy (communicating or waiting for an answer), and True at all other times.

This property is read-only.

LocalHost Property (SMPP Component)

The name of the local host or user-assigned IP interface through which connections are initiated or accepted.

Syntax

C#
VB.NET

public string LocalHost { get; set; }

Public Property LocalHost As String

Default Value

Remarks

This property contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multihomed hosts (machines with more than one IP interface) setting LocalHost to the IP address of an interface will make the component initiate connections (or accept in the case of server components) only through that interface. It is recommended to provide an IP address rather than a hostname when setting this property to ensure the desired interface is used.

If the component is connected, the LocalHost property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface).

Note: LocalHost is not persistent. You must always set it in code, and never in the property window.

MessageExpiration Property (SMPP Component)

This property denotes the validity period of the current message.

Syntax

C#
VB.NET

public string MessageExpiration { get; set; }

Public Property MessageExpiration As String

Default Value

Remarks

This property indicates the Message Center expiration time, after which the message should be discarded if not delivered to the destination. It can be set using absolute or relative time formats.

Absolute Time Format is a 16-character string represented as "YYMMDDhhmmsstnnp" where:


YY	the last two digits of the year (00-99)
MM	month (01-12)
DD	day (01-31)
hh	hour (00-23)
mm	minute (00-59)
ss	second (00-59)
t	tenths of a second (0-9)
nn	quarter-hour time difference between local time and UTC time (00-48)
p	"+" or "-" indicating the direction of the time offset in `nn`

Relative Time Format is the same 16-character string where "p" should be set to "R" for "relative". For relative time, "tnn" are ignored and thus should be set to a constant value of "000".

  smppMessagePriorityLow
  smppMessagePriorityNormal
  smppMessagePriorityHigh
  smppMessagePriorityUrgent
End Enum

Default Value

Remarks

When sending a message, this property will tell the server what type of priority to assign to the message. The effect of the message priority setting depends on the Message Center (MC) manufacturer and the network on which the target recipient lies. For example, some MCs may immediately forward "urgent" messages, some networks may use the priority setting as a visual indicator of the message's urgency (e.g., blinking icons), and some networks may entirely ignore the priority setting.

Password Property (SMPP Component)

This property contains the user's password.

Syntax

C#
VB.NET

public string Password { get; set; }

Public Property Password As String

Default Value

Remarks

This property contains the user's password. When binding to the SMPPServer, the client must provide a known user identifier and a valid password for that Id.

The two ways to bind are (1) by calling Connect with a user identifier and password, which will set the UserId and this property before connecting; or (2) by setting those two properties and calling SendMessage while not connected.

The default value is version 3.4 because it is the most widely used version of the protocol.

Choosing the highest mutually supported version is generally recommended. Version 3.4 is the default value; however, if version 5.0 is supported, it is recommended.

SSLAcceptServerCert Property (SMPP Component)

Instructs the component to unconditionally accept the server certificate that matches the supplied certificate.

Syntax

C#
VB.NET

public Certificate SSLAcceptServerCert { get; set; }

Public Property SSLAcceptServerCert As Certificate

Remarks

If it finds any issues with the certificate presented by the server, the component will normally terminate the connection with an error.

You may override this behavior by supplying a value for SSLAcceptServerCert. If the certificate supplied in SSLAcceptServerCert is the same as the certificate presented by the server, then the server certificate is accepted unconditionally, and the connection will continue normally.

Note: This functionality is provided only for cases in which you otherwise know that you are communicating with the right server. If used improperly, this property may create a security breach. Use it at your own risk.

Please refer to the Certificate type for a complete list of fields.

Remarks

This property specifies whether TLS/SSL is enabled in the component. When False (default), the component operates in plaintext mode. When True, TLS/SSL is enabled.

TLS/SSL may also be enabled by setting SSLStartMode. Setting SSLStartMode will automatically update this property value.

This property is not available at design time.

SSLProvider Property (SMPP Component)

The Secure Sockets Layer/Transport Layer Security (SSL/TLS) implementation to use.

Syntax

C#
VB.NET

public SMPPSSLProviders SSLProvider { get; set; }

enum SMPPSSLProviders {
  sslpAutomatic,
  sslpPlatform,
  sslpInternal
}

Public Property SSLProvider As SmppSSLProviders

Enum SMPPSSLProviders
  sslpAutomatic
  sslpPlatform
  sslpInternal
End Enum

Default Value

Remarks

This property specifies the SSL/TLS implementation to use. In most cases the default value of 0 (Automatic) is recommended and should not be changed. When set to 0 (Automatic), the component will select whether to use the platform implementation or the internal implementation depending on the operating system as well as the TLS version being used.

Possible values are as follows:


0 (sslpAutomatic - default)	Automatically selects the appropriate implementation.
1 (sslpPlatform)	Uses the platform/system implementation.
2 (sslpInternal)	Uses the internal implementation.

Additional Notes

In most cases using the default value (Automatic) is recommended. The component will select a provider depending on the current platform.

When Automatic is selected, on Windows, the component will use the platform implementation. On Linux/macOS, the component will use the internal implementation. When TLS 1.3 is enabled via SSLEnabledProtocols, the internal implementation is used on all platforms.

The .NET Standard library will always use the internal implementation on all platforms.

  sslExplicit,
  sslNone
}

Public Property SSLStartMode As SmppSSLStartModes

Enum SMPPSSLStartModes
  sslAutomatic
  sslImplicit
  sslExplicit
  sslNone
End Enum

Default Value

Remarks

The SSLStartMode property may have one of the following values:


0 (sslAutomatic)	If the remote port is set to the standard plaintext port of the protocol (where applicable), the component will behave the same as if SSLStartMode is set to sslExplicit. In all other cases, SSL negotiation will be implicit (sslImplicit).
1 (sslImplicit)	The SSL negotiation will start immediately after the connection is established.
2 (sslExplicit)	The component will first connect in plaintext, and then will explicitly start SSL negotiation through a protocol command such as STARTTLS.
3 (sslNone - default)	No SSL negotiation; no SSL security. All communication will be in plaintext mode.

SystemType Property (SMPP Component)

This property contains a string representing the type of system during a connection.

Syntax

C#
VB.NET

public string SystemType { get; set; }

Public Property SystemType As String

Default Value

Remarks

This property contains a string representing the type of system during a connection. Some SMS servers require that a system type be supplied during connection. The system type is a string representation, usually as an abbreviation, of a particular kind of system. The string cannot exceed 12 bytes.

Timeout Property (SMPP Component)

The timeout for the component.

Syntax

C#
VB.NET

public int Timeout { get; set; }

Public Property Timeout As Integer

Default Value

Remarks

If the Timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.

If Timeout is set to a positive value, the component will wait for the operation to complete before returning control.

The component 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 component throws an exception.

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 Timeout property is 60 seconds.

UserId Property (SMPP Component)

This property is used for identification with the SMPP service.

Syntax

C#
VB.NET

public string UserId { get; set; }

Public Property UserId As String

Default Value

Remarks

This property is used for identification with the SMPP service. When binding to the SMPPServer, the client must provide a known user identifier and a valid password for that Id.

The two ways to bind are (1) by calling Connect with a user Id and password, which will set the UserId and Password properties before connecting; or (2) by setting those two properties and calling SendMessage while not connected.

AddRecipient Method (SMPP Component)

This method will add a recipient of the specified type to the recipient list.

Syntax

C#
VB.NET

public void AddRecipient(int recipientType, string recipientAddress);

Async Version

Public Sub CheckLink()

Async Version
Public Sub CheckLink() As Task
Public Sub CheckLink(cancellationToken As CancellationToken) As Task

Remarks

This method will check the connection to the server. This method is used to ensure that the host on the other end of the connection is still active, or that it is still available. Although a socket connection may still be available between the client and server, the SMS application on the server may have been taken offline without releasing the socket or the CPU may be bogged down. This method will send a PDU to the server and wait the length of Timeout for a response.

CheckMessageStatus Method (SMPP Component)

This method will retrieve the status of the specified message.

Syntax

C#
VB.NET

Async Version
Public Function Config(ByVal ConfigurationString As String) As Task(Of String)
Public Function Config(ByVal ConfigurationString As String, cancellationToken As CancellationToken) As Task(Of String)

Remarks

Config is a generic method available in every component. It is used to set and retrieve configuration settings for the component.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

Public Delegate Sub OnConnectedHandler(sender As Object, e As SMPPConnectedEventArgs)

Public Class SMPPConnectedEventArgs Inherits EventArgs
  Public ReadOnly Property StatusCode As Integer
  Public ReadOnly Property Description As String
End Class

Remarks

After establishing a socket connection to the SMPPServer, the component will attempt to send a bind as a transmitter command. Upon completion of this operation, the server will respond with either a success or failure state, which will be reflected in the Connected event's parameters.

StatusCode will contain the command status (error code) returned by the server. For a StatusCode of 0, Description will be OK. Otherwise, it will contain a standard interpretation of the error.

Public Class SMPPDisconnectedEventArgs Inherits EventArgs
  Public ReadOnly Property StatusCode As Integer
  Public ReadOnly Property Description As String
End Class

Remarks

After sending an unbind operation to the server, this event will be fired containing the results of that operation. This event may also be fired if the socket connection to the service is lost.

If the event was fired because of an unbind operation, StatusCode will contain the command status set by the server. Otherwise, it will contain the socket code for the type of disconnection. For a status code value of 0, Description will contain OK. Otherwise, it will contain a standard interpretation of the value in StatusCode.

Error Event (SMPP Component)

This event is fired when the server detects an error.

Syntax

End Class

Remarks

If the server sends an error not related to a command sent from the component, the component will fire an Error event containing information related to the error.

ErrorCode will contain the code sent by the server, and Description will contain a standard interpretation of that code.

MessageIn Event (SMPP Component)

This event is fired upon receipt of a message.

Syntax

C#
VB.NET

public event OnMessageInHandler OnMessageIn;

public delegate void OnMessageInHandler(object sender, SMPPMessageInEventArgs e);

public class SMPPMessageInEventArgs : EventArgs {
  public string SourceAddress { get; }
  public string ScheduleDeliveryTime { get; }
  public string ValidityPeriod { get; }
  public string Message { get; }
  public int MessagePart { get; }
  public int MessagePartCount { get; }
  public int MessagePartReference { get; }
  public string DestinationAddress { get; }
  public int ResponseErrorCode { get; set; }
}

Public Event OnMessageIn As OnMessageInHandler

Public Delegate Sub OnMessageInHandler(sender As Object, e As SMPPMessageInEventArgs)

Public Class SMPPMessageInEventArgs Inherits EventArgs
  Public ReadOnly Property SourceAddress As String
  Public ReadOnly Property ScheduleDeliveryTime As String
  Public ReadOnly Property ValidityPeriod As String
  Public ReadOnly Property Message As String
  Public ReadOnly Property MessagePart As Integer
  Public ReadOnly Property MessagePartCount As Integer
  Public ReadOnly Property MessagePartReference As Integer
  Public ReadOnly Property DestinationAddress As String
  Public Property ResponseErrorCode As Integer
End Class

Remarks

When a message is received, the SMPP component will parse the sender's message into the SourceAddress, ScheduleDeliveryTime, ValidityPeriod, and Message fields.

The SourceAddress parameter is the address of the originator of the message.

The DestinationAddress parameter holds the address of the recipient.

The ScheduleDeliveryTime parameter is the delivery time at which the short message is scheduled to be forwarded to another Message Center (MC). This will be an empty string if it is not scheduled.

The ValidityPeriod parameter is applicable only if this short message is being forwarded to another MC. When this occurs, it specifies how long the receiving MC should retain the Short Message (SM) and continue trying to deliver it. This will be an empty string if the current validity period is unavailable.

The Message parameter is the plaintext portion of the message body.

If the incoming message is a part of a larger message (the message was split up into several parts), the MessagePartCount, MessagePart, and MessagePartReference parameters will be set. MessagePartCount will hold the total number of parts for the message. MessagePart will indicate the current part's location in the message to determine the order when reassembling the message. This will be a value from 1 to MessagePartCount. MessagePartReference holds a reference value that will be the same across all parts for the message.

The ResponseErrorCode parameter may be set to return an error condition to the server. This corresponds to the command_status protocol-level field of the response.

MessageStatus Event (SMPP Component)

This event is fired upon receipt of a message.

Syntax

C#
VB.NET

public event OnMessageStatusHandler OnMessageStatus;

public delegate void OnMessageStatusHandler(object sender, SMPPMessageStatusEventArgs e);

public class SMPPMessageStatusEventArgs : EventArgs {
  public string MessageId { get; }
  public int MessageState { get; }
  public int MessageError { get; }
  public string FinalDate { get; }
}

Public Event OnMessageStatus As OnMessageStatusHandler

Public Delegate Sub OnMessageStatusHandler(sender As Object, e As SMPPMessageStatusEventArgs)

Public Class SMPPMessageStatusEventArgs Inherits EventArgs
  Public ReadOnly Property MessageId As String
  Public ReadOnly Property MessageState As Integer
  Public ReadOnly Property MessageError As Integer
  Public ReadOnly Property FinalDate As String
End Class

Remarks

When a CheckMessageStatus is called, the SMPP component will retrieve the status of the message represented by MessageId from the server, parse the response, and fire MessageStatus.

MessageState represents the last known state the message was left in on the SMPPServer. This code is version specific. For v3.4:


1	ENROUTE, the message is en route.
2	DELIVERED, the message is delivered.
3	EXPIRED, the message validity period expired.
4	DELETED, the message has been deleted.
5	UNDELIVERABLE, the message is undeliverable.
6	ACCEPTED, the message has been read on behalf of subscriber by customer service.
7	UNKNOWN, the message is in an invalid state.
8	REJECTED, the message is in a rejected state.

For v5.0:


0	SCHEDULED, the message is scheduled for delivery, but it has not yet been delivered.
1	ENROUTE, the message is en route.
2	DELIVERED, the message is delivered.
3	EXPIRED, the message validity period expired.
4	DELETED, the message has been deleted.
5	UNDELIVERABLE, the message is undeliverable.
6	ACCEPTED, the message has been read on behalf of subscriber by customer service.
7	UNKNOWN, the message is in an invalid state.
8	REJECTED, the message is in a rejected state.
9	SKIPPED, the message was accepted but not delivered.

MessageError will contain an error code representing any failure encountered during message delivery. This code may be vendor-specific.

FinalDate contains a human-readable string representing the date on which the message was delivered. If the message was not delivered, this parameter will be empty.

PITrail Event (SMPP Component)

This event is fired once for each protocol data unit (PDU) sent between the client and server.

Syntax

C#
VB.NET

public event OnPITrailHandler OnPITrail;

public delegate void OnPITrailHandler(object sender, SMPPPITrailEventArgs e);

public class SMPPPITrailEventArgs : EventArgs {
  public int Direction { get; }
  public string PDU { get; }
  public byte[] PDUB { get; }
  public int CommandLength { get; }
  public int CommandId { get; }
  public string CommandDescription { get; }
  public string CommandStatus { get; }
  public int SequenceNumber { get; }
}

Public Event OnPITrail As OnPITrailHandler

Public Delegate Sub OnPITrailHandler(sender As Object, e As SMPPPITrailEventArgs)

Public Class SMPPPITrailEventArgs Inherits EventArgs
  Public ReadOnly Property Direction As Integer
  Public ReadOnly Property PDU As String
  Public ReadOnly Property PDUB As Byte()
  Public ReadOnly Property CommandLength As Integer
  Public ReadOnly Property CommandId As Integer
  Public ReadOnly Property CommandDescription As String
  Public ReadOnly Property CommandStatus As String
  Public ReadOnly Property SequenceNumber As Integer
End Class

Remarks

Whenever either the component or the SMPPServer sends any data across the connection, the component will fire a PITrail event containing that data. It will usually be in SMPP-PDU format.

A PDU will contain at least the SMPP header, which is always 16 bytes long. The first four bytes represent the total length of the PDU, including the 16-byte header. The next four bytes are the command Id associated with the PDU. The command Id of a response PDU is always the command Id to which it is responding plus 0x80000000.

The component parses the values contained in the PDU header into the appropriate fields. The CommandLength, CommandId, CommandStatus, and SequenceNumber parameters contain these parsed values.

The third set of four bytes are the command status (status code) of the command. All originating commands will have a status code of 0x00000000, which will be ignored by the receiver. The field is only set in response PDUs to indicate the status of the originating command. The final four bytes represent the sequence number of the command. All response PDUs will contain the same sequence number as the originating command.

ReadyToSend Event (SMPP Component)

This event is fired when the component is ready to send data.

Syntax

C#
VB.NET

public event OnReadyToSendHandler OnReadyToSend;

public delegate void OnReadyToSendHandler(object sender, SMPPReadyToSendEventArgs e);

public class SMPPReadyToSendEventArgs : EventArgs {
}

Public Event OnReadyToSend As OnReadyToSendHandler

Public Delegate Sub OnReadyToSendHandler(sender As Object, e As SMPPReadyToSendEventArgs)

Public Class SMPPReadyToSendEventArgs Inherits EventArgs
End Class

Remarks

The ReadyToSend event indicates that the underlying Transmission Control Protocol (TCP)/IP subsystem is ready to accept data after a failed SendBytes. This event also is fired immediately after a connection to the remote host is established.

SSLServerAuthentication Event (SMPP Component)

Fired after the server presents its certificate to the client.

Syntax

C#
VB.NET

public event OnSSLServerAuthenticationHandler OnSSLServerAuthentication;

public delegate void OnSSLServerAuthenticationHandler(object sender, SMPPSSLServerAuthenticationEventArgs e);

public class SMPPSSLServerAuthenticationEventArgs : EventArgs {
  public string CertEncoded { get; }
  public byte[] CertEncodedB { get; }
  public string CertSubject { get; }
  public string CertIssuer { get; }
  public string Status { get; }
  public bool Accept { get; set; }
}

Public Event OnSSLServerAuthentication As OnSSLServerAuthenticationHandler

Public Delegate Sub OnSSLServerAuthenticationHandler(sender As Object, e As SMPPSSLServerAuthenticationEventArgs)

Public Class SMPPSSLServerAuthenticationEventArgs Inherits EventArgs
  Public ReadOnly Property CertEncoded As String
  Public ReadOnly Property CertEncodedB As Byte()
  Public ReadOnly Property CertSubject As String
  Public ReadOnly Property CertIssuer As String
  Public ReadOnly Property Status As String
  Public Property Accept As Boolean
End Class

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 (SMPP Component)

Fired when secure connection progress messages are available.

Syntax

C#
VB.NET

public event OnSSLStatusHandler OnSSLStatus;

public delegate void OnSSLStatusHandler(object sender, SMPPSSLStatusEventArgs e);

public class SMPPSSLStatusEventArgs : EventArgs {
  public string Message { get; }
}

Public Event OnSSLStatus As OnSSLStatusHandler

Public Delegate Sub OnSSLStatusHandler(sender As Object, e As SMPPSSLStatusEventArgs)

Public Class SMPPSSLStatusEventArgs Inherits EventArgs
  Public ReadOnly Property Message As String
End Class

Remarks

The event is fired for informational and logging purposes only. This event tracks the progress of the connection.

The ListStoreCertificates method may be called after setting CertStoreType to `cstPKCS11`, CertStorePassword to the PIN, and CertStore to the full path of the PKCS#11 DLL. The certificate information returned in the CertList event's `CertEncoded` parameter may be saved for later use. When using a certificate, pass the previously saved security key information as the Store and set StorePassword to the PIN. Code Example. SSH Authentication with Security Key: `certmgr.CertStoreType = CertStoreTypes.cstPKCS11; certmgr.OnCertList += (s, e) => { secKeyBlob = e.CertEncoded; }; certmgr.CertStore = @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll"; certmgr.CertStorePassword = "123456"; //PIN certmgr.ListStoreCertificates(); sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11, secKeyBlob, "123456", "*"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22);`

Config Settings (SMPP Component)

The component 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 component, access to these internal properties is provided through the Config method.

SMPP Config Settings

AddressRange: Specifies the addr_range parameter when binding.

The addr_range parameter is used when binding as a receiver or transceiver to specify a set of short message entity (SME) addresses serviced by the external SME (ESME) client. A single SME address may be specified in the address_range parameter. UNIX Regular Expression notation should be used to specify a range of addresses. Messages addressed to any destination in this range shall be routed to the ESME.

Note 1: For IP addresses, it is only possible to specify a single IP address. A range of IP addresses is not allowed. IP version 6.0 is not currently supported in this version of the protocol.

Note 2: It is likely that the addr_range field is not supported or deliberately ignored on most Message Centers (MCs). Most carriers will not allow an ESME to control the message routing because this can carry the risk of incorrectly routing messages. In such circumstances, the ESME will be requested to set the field to NULL.

BinaryDataCoding: Whether or not to binary encode the message when DataCoding is set.

By default, when the DataCoding configuration setting is used, the component will treat the message as binary. This configuration setting can be set to false to send the text user data instead.

BindAsReceiver: Causes the component to bind as a receiver.

This configuration setting will instruct the component to bind to the SMPP service as a receiver instead of a transceiver.

BindAsTransmitter: Causes the component to bind as a transmitter.

This configuration setting will instruct the component to bind to the SMPP service as a transmitter instead of a transceiver.

CustomTLV: Optional TLV parameters added after the mandatory parameters and before the payload.

The format of the tag length value (TLV) parameter is as follows:

One two-byte integer containing the parameter type (tag).
One two-byte integer indicating the length of the data contained in this parameter.
The variable-length parameter data itself.

All of these values must be hex-encoded before setting the CustomTLV configuration setting.

For instance, to add a gn_lookup_userdata parameter, the type/tag is decimal 5633 (that's 0x1601 in hex), and the data in this example is "Hello World", which is 11 characters in length. So the TLV is as follows: 5633 + 11 + "Hello World", or 0x16 0x01 0x00 0x0b and then the ASCII text "Hello World". When hex-encoded, this yields the string "1601000b48656c6c6f20576f726c64". This is the value you would then use to set the CustomTLV configuration setting. You are not restricted to only one optional parameter. Multiple TLV parameters may be concatenated together.

Note: This is advanced functionality, and the component does not verify the data in this configuration setting before transmission. After the component internally decodes the string back into binary, it is passed on inside the protocol data unit (PDU) as-is without validation or modification.

This configuration setting is applicable only when using the SendMessage or SendData methods.

DataCoding: The data encoding mechanism to be used for the current message.

This configuration setting informs the message recipient about how data were encoded. The possible values are as follows:


0	MC Specific encoding
1	IA5 (CCITT T.50)/ASCII (ANSI X3.4)
2	Octet unspecified (8-bit binary)
3	Latin 1 (ISO-8859-1)
4	Octet unspecified (8-bit binary)
5	JIS (X 0208-1990)
6	Cyrillic (ISO-8859-5)
7	Latin/Hebrew (ISO-8859-8)
8	UCS2 (ISO/IEC-10646)
9	Pictogram Encoding
10	ISO-2022-JP (Music Codes)
11	Reserved
12	Reserved 2
13	Extended Kanji JIS (X 0212-1990)
14	KS C 5601

DestinationNPI: The Number Planning Indicator for the destination ESME.

When sending messages, this configuration setting is used to indicate the numbering plan the destination ESME. For a list of possible values, please see SourceNPI.

DestinationTON: The Type of Number for the destination ESME.

When sending messages, this configuration setting is used to indicate the Type of Number for the destination ESME. For a list of possible values, please see SourceTON.

DoSplitLargeMessages: Splits long messages and returns the UDH and Message Parts.

This configuration setting accepts a string that will be the long message to be split into parts. The user data header (UDH) and Message Parts will be returned in hex, in the following format:

[UDH1],[MessagePart1];[UDH2],[MessagePart2];[UDH3],[MessagePart3]

HexString: A hex-encoded binary string to be sent to the current recipient.

When set, this configuration setting will cause the component to internally call SendMessage with the binary contents of the hex-encoded string. The return value when setting this property is the server-assigned Id of the message. Querying this property will result in an empty string.

Note: When using HexString, DataCoding must be set to 8, and the value provided to this configuration setting should be the UTF-16 hex-encoded message.

IntermediateNotification: Causes the component to request intermediate notification.

This configuration setting will request intermediate notification. By default, intermediate notification is not requested.

MaxCIMDSMSLength: Indicates the maximum SMS message length for the CIMD protocol.

This configuration setting is applicable only when SplitLargeMessages is True and Protocol is set to CIMD2. The configuration setting controls the maximum size of SMS messages before they are split and has a default value of 160.

MaxSMSLength: Indicates the maximum SMS message length.

This configuration setting is applicable only when SplitLargeMessages is True. The setting controls the maximum size of SMS messages before they are split and has a default value of 140.

MCReceipt: The Type of MC Delivery Receipt requested.

When sending a message, this configuration setting is used to determine whether or not an MC delivery receipt is requested. This value is 0 by default, and no receipt is requested. The possible values are as follows:


0	No MC Delivery Receipt requested (default).
1	MC Delivery Receipt is requested after final delivery (success or failure).
2	MC Delivery Receipt is requested after a failed delivery.
3	MC Delivery Receipt is requested after a successful delivery.

MessageInReceiptedMessageId: The receipted_message_id field of an incoming deliver_sm PDU.

This configuration setting indicates the Id of the message being receipted in an MC delivery receipt.

Note: This is applicable only within the MessageIn event.

MessageMode: The Type of Messaging Mode requested.

When sending a message, this configuration setting is used to specify the Messaging Mode in the outgoing request. For incoming messages, this value can be queried from within the MessageIn event. The possible values are as follows:


0	Default SMSC Mode (e.g., Store and Forward).
1	Datagram mode.
2	Forward (i.e., Transaction) mode.
3	Store and Forward mode.

MessageType: The Type of Message.

When sending a message, this configuration setting is used to specify the Message Type in the outgoing request. For incoming messages, this value can be queried from within the MessageIn event. The possible values are as follows:


0	Default message Type (i.e., normal message).
1	Short Message contains MC Delivery Receipt.
2	Short Message contains Intermediate Delivery Notification.

PDUFormat: The format of the PDU.

Decides the format of the PDU parameter when decoding a PDU for the PITrail event. When set to Hex (1), the PDU will be encoded as a hex string. When set to Verbose (2) the PDU will be a longer hex dump.


0	Raw (Default)
1	Hex string
2	Verbose

ProtocolId: The protocol identifier.

This configuration setting allows control of the protocol identifier field value used in the outgoing messages.

ReplaceIfPresent: Indicates whether the replace_if_present_flag is enabled when sending a message.

This configuration indicates whether the replace_if_present_flag is enabled when sending a message. By default, this value is False, and the flag is disabled. When enabled (True), this indicates to the SMSC that the user wishes to replace a previously submitted message that is still pending delivery. If the previous message is still pending delivery, the new message will replace it. If the previous message has already been delivered or does not exist, the new message will also be delivered.

SMEAcknowledgement: The Type of SME originated acknowledgment requested.

When sending a message, this configuration setting is used to determine whether or not an SME acknowledgment is requested. This value is 0 by default, and no acknowledgment is requested. The possible values are as follows:


0	No SME acknowledgment requested (default).
1	SME delivery acknowledgment is requested.
2	SME manual/user acknowledgment is requested.
3	Both delivery and manual/user acknowledgment is requested.

SourceNPI: The Number Planning Indicator for the ESME.

When binding, this configuration setting is used to specify the numbering plan of the ESME. Mobiles tend to set this value to 1. Because most ESMEs are mobiles, the default value for SourceNPI is 1. The possible value are as follows:


Unknown (0)
ISDN (1)
Data (3)
Telex (4)
LandMobile (6)
National (8)
Private (9)
ERMES (10)
Internet (14)

Unknown (0)	The number type is unknown
International (1)	The number includes the international trunk prefix
National (2)	The number includes the national trunk prefix
NetworkSpecific (3)	The number exists on a network that uses a specific delivery protocol
SubscriberNumber (4)	The number is just the subscriber number, without prefixes
Alphanumeric (5)	The address is human-readable (contains letters and digits)
Abbreviated (6)	The number is abbreviated

SplitLargeMessages: Determines whether large messages are split into multiple parts.

The default value is False. If set to true and the message is larger than MaxSMSLength (or MaxCIMDSMSLength), the message will automatically be split into parts when SendMessage is called.

Note: This is valid only for GSM networks.

When receiving a message that has been split, the MessageIn event provides parameters to reassemble the message.

SplitMessageMethod: Determines how large messages are split into multiple parts.

The component can split large messages using either the UDH or segmentation and reassembly (SAR) method. The mode used is determined by this configuration setting. The possible values are as follows:


0	UDH (Default)
1	SAR

StatusReportRequest: Defines in what cases a status report is created by the server.

This configuration setting is applicable only when Protocol is set to smppCIMD2. This may be set to request that the server create a status report for the given conditions. The assigned value should be the sum of all desired conditions. For instance, a value of 62 means that a report should be created for all events except for a temporary error. Possible flags are as follows:


1	Temporary Error
2	Validity Period Expired
4	Delivery Failed
8	Delivery Successful
16	Message Canceled
32	Message Deleted By The Operator

SubAddr: Defines a unique index for application instance.

This configuration setting is useful for correct delivery of status reports when multiple instances of the same application are connected.

This configuration setting is applicable only when Protocol is set to smppCIMD2.

SynchronousSendCommand: Controls whether SendCommand behaves synchronously or asynchronously.

The default value is True, which means SendCommand will not return until a response has been received. If set to False, the component returns and does not wait for a response from the server.

SynchronousSendMessage: Controls whether SendMessage behaves synchronously or asynchronously.

The default value is True, which means SendMessage will not return until a response has been received. If set to False, the component returns the sequence number used and does not wait for a response from the server. You may then monitor the PITrail event to match the response from the server to the sent message.

UseGSM7BitEncoding: Whether or not to use GSM 7-bit encoding.

When set to True (False by default), this will instruct the component to use 7-bit GSM encoding.

UseGSM7bitEncodingCompression: Whether to compress GSM 7-bit encoded characters.

When set to True (True by default), the component will compress GSM 7-bit encoded characters. Some devices do not support compression. Setting this to False may allow them to be displayed.

This configuration setting applies only when UseGSM7BitEncoding is True.

WaitForBanner: Specifies the CIMD2 banner the component will wait for when connecting.

This configuration setting is applicable only when Protocol is set to smppCIMD2. If set, the component will wait for a banner containing this string to be returned by the server before proceeding with the connection.

TCPClient Config Settings

CloseStreamAfterTransfer: If true, the component will close the upload or download stream after the transfer.

This configuration setting determines whether the input or output stream is closed after the transfer completes. When set to True (default), all streams will be closed after a transfer is completed. To keep streams open after the transfer of data, set this to False. The default value is True.

ConnectionTimeout: Sets a separate timeout value for establishing a connection.

When set, this configuration setting allows you to specify a different timeout value for establishing a connection. Otherwise, the component will use Timeout for establishing a connection and transmitting/receiving data.

FirewallAutoDetect: Tells the component whether or not to automatically detect and use firewall system settings, if available.

This configuration setting is provided for use by components that do not directly expose Firewall properties.

FirewallHost: Name or IP address of firewall (optional).

If a FirewallHost is given, requested connections will be authenticated through the specified firewall when connecting.

If the FirewallHost setting is set to a Domain Name, a DNS request is initiated. Upon successful termination of the request, the FirewallHost setting is set to the corresponding address. If the search is not successful, an error is returned.

Note: This setting is provided for use by components that do not directly expose Firewall properties.

FirewallListener: If true, the component binds to a SOCKS firewall as a server (TCPClient only).

This entry is for TCPClient only and does not work for other components that descend from TCPClient.

If this entry is set, the component acts as a server. RemoteHost and RemotePort are used to tell the SOCKS firewall in which address and port to listen to. The firewall rules may ignore RemoteHost, and it is recommended that RemoteHost be set to empty string in this case.

RemotePort is the port in which the firewall will listen to. If set to 0, the firewall will select a random port. The binding (address and port) is provided through the ConnectionStatus event.

The connection to the firewall is made by calling the Connect method.

FirewallPassword: Password to be used if authentication is to be used when connecting through the firewall.

If FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the given firewall. If the authentication fails, the component throws an exception.

Note: This setting is provided for use by components that do not directly expose Firewall properties.

FirewallPort: The TCP port for the FirewallHost;.

The FirewallPort is set automatically when FirewallType is set to a valid value.

Note: This configuration setting is provided for use by components that do not directly expose Firewall properties.

FirewallType: Determines the type of firewall to connect through.

Possible values are as follows:


0	No firewall (default setting).
1	Connect through a tunneling proxy. FirewallPort is set to 80.
2	Connect through a SOCKS4 Proxy. FirewallPort is set to 1080.
3	Connect through a SOCKS5 Proxy. FirewallPort is set to 1080.
10	Connect through a SOCKS4A Proxy. FirewallPort is set to 1080.

Note: This setting is provided for use by components that do not directly expose Firewall properties.

FirewallUser: A user name if authentication is to be used connecting through a firewall.

If the FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the Firewall. If the authentication fails, the component throws an exception.

Note: This setting is provided for use by components that do not directly expose Firewall properties.

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

When set, TCPKeepAlive will automatically be set to True. 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 configuration setting specifies the interval at which the successive keep-alive packets are sent in milliseconds. This system default if this value is not specified here is 1 second.

Note: This value is not applicable in macOS.

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

When set, TCPKeepAlive will automatically be set to True. By default, the operating system will determine the time a connection is idle before a Transmission Control Protocol (TCP) keep-alive packet is sent. This system default if this value is not specified here is 2 hours. In many cases, a shorter interval is more useful. Set this value to the desired interval in milliseconds.

Linger: When set to True, connections are terminated gracefully.

This property controls how a connection is closed. The default is True.

In the case that Linger is True (default), two scenarios determine how long the connection will linger. In the first, if LingerTime is 0 (default), the system will attempt to send pending data for a connection until the default IP timeout expires.

In the second scenario, if LingerTime is a positive value, the system will attempt to send pending data until the specified LingerTime is reached. If this attempt fails, then the system will reset the connection.

The default behavior (which is also the default mode for stream sockets) might result in a long delay in closing the connection. Although the component returns control immediately, the system could hold system resources until all pending data are sent (even after your application closes).

Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (e.g., by a client acknowledgment), setting this property to False might be the appropriate course of action.

LingerTime: Time in seconds to have the connection linger.

LingerTime is the time, in seconds, the socket connection will linger. This value is 0 by default, which means it will use the default IP timeout.

LocalHost: The name of the local host through which connections are initiated or accepted.

The LocalHost setting contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multihomed hosts (machines with more than one IP interface), setting LocalHost to the value of an interface will make the component initiate connections (or accept in the case of server components) only through that interface.

If the component is connected, the LocalHost setting shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface).

LocalPort: The port in the local host where the component binds.

This configuration setting must be set before a connection is attempted. It instructs the component to bind to a specific port (or communication endpoint) in the local machine.

Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by LocalPort after the connection is established.

LocalPort cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error.

This configuration setting is useful when trying to connect to services that require a trusted port on the client side. An example is the remote shell (rsh) service in UNIX systems.

MaxLineLength: The maximum amount of data to accumulate when no EOL is found.

MaxLineLength is the size of an internal buffer, which holds received data while waiting for an EOL string.

If an EOL string is found in the input stream before MaxLineLength bytes are received, the DataIn event is fired with the EOL parameter set to True, and the buffer is reset.

If no EOL is found, and MaxLineLength bytes are accumulated in the buffer, the DataIn event is fired with the EOL parameter set to False, and the buffer is reset.

The minimum value for MaxLineLength is 256 bytes. The default value is 2048 bytes.

MaxTransferRate: The transfer rate limit in bytes per second.

This configuration setting can be used to throttle outbound TCP traffic. Set this to the number of bytes to be sent per second. By default, this is not set and there is no limit.

ProxyExceptionsList: A semicolon separated list of hosts and IPs to bypass when using a proxy.

This configuration setting optionally specifies a semicolon-separated list of hostnames or IP addresses to bypass when a proxy is in use. When requests are made to hosts specified in this property, the proxy will not be used. For instance:

www.google.com;www.nsoftware.com

TCPKeepAlive: Determines whether or not the keep alive socket option is enabled.

If set to True, the socket's keep-alive option is enabled and keep-alive packets will be sent periodically to maintain the connection. Set KeepAliveTime and KeepAliveInterval to configure the timing of the keep-alive packets.

Note: This value is not applicable in Java.

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.

UseIPv6: Whether to use IPv6.

When set to 0 (default), the component will use IPv4 exclusively. When set to 1, the component will use IPv6 exclusively. To instruct the component to prefer IPv6 addresses, but use IPv4 if IPv6 is not supported on the system, this setting should be set to 2. The default value is 0. Possible values are as follows:


0	IPv4 only
1	IPv6 only
2	IPv6 with IPv4 fallback

UseNTLMv2: Whether to use NTLM V2.

When authenticating with NTLM, this setting specifies whether NTLM V2 is used. By default this value is False and NTLM V1 will be used. Set this to True to use NTLM V2.

SSL Config Settings

CACertFilePaths: The paths to CA certificate files when using Mono on Unix/Linux.

This configuration setting specifies the paths on disk to certificate authority (CA) certificate files when using Mono on Unix/Linux. It is not applicable in any other circumstances.

The value is formatted as a list of paths separated by semicolons. The component 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

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.

ReuseSSLSession: Determines if the SSL session is reused.

If set to True, the component 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 component is the same.

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

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

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

This configuration setting specifies whether the component will check the Certificate Revocation List (CRL) specified by the server certificate. If set to 1 or 2, the component will first obtain the list of CRL URLs from the server certificate's CRL distribution points extension. The component 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 component throws an exception.

When set to 0 (default), the CRL check will not be performed by the component. 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 component will use OCSP to check the validity of the server certificate. If set to 1 or 2, the component will first obtain the Online Certificate Status Protocol (OCSP) URL from the server certificate's OCSP extension. The component 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 component throws an exception.

When set to 0 (default), the component 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

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 component 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:


TLS1.3	12288 (Hex 3000)
TLS1.2	3072 (Hex C00) (Default - Client and Server)
TLS1.1	768 (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 component 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 component 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.

Note: When SSLProvider is set to Internal this value is automatically set to true. This is needed for proper validation when using the internal provider.

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 component 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 component 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.

SSLNegotiatedKeyExchange: Returns the negotiated key exchange algorithm.

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

SSLNegotiatedKeyExchangeStrength: Returns the negotiated key exchange algorithm strength.

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

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:


0x00000001	Ignore time validity status of certificate.
0x00000002	Ignore time validity status of CTL.
0x00000004	Ignore non-nested certificate times.
0x00000010	Allow unknown certificate authority.
0x00000020	Ignore wrong certificate usage.
0x00000100	Ignore unknown certificate revocation status.
0x00000200	Ignore unknown CTL signer revocation status.
0x00000400	Ignore unknown certificate authority revocation status.
0x00000800	Ignore unknown root revocation status.
0x00008000	Allow test root certificate.
0x00004000	Trust test root certificate.
0x80000000	Ignore non-matching CN (certificate CN non-matching server name).

This functionality is currently not available in Java or 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
... Intermediate Cert...
eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w

... Root Cert...
d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA
-----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 component 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 component throws an exception.

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)

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

Socket Config Settings

AbsoluteTimeout: Determines whether timeouts are inactivity timeouts or absolute timeouts.

If AbsoluteTimeout is set to True, any method that does not complete within Timeout seconds will be aborted. By default, AbsoluteTimeout is False, and the timeout is an inactivity timeout.

Note: This option is not valid for User Datagram Protocol (UDP) ports.

FirewallData: Used to send extra data to the firewall.

When the firewall is a tunneling proxy, use this property to send custom (additional) headers to the firewall (e.g., headers for custom authentication schemes).

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. In some cases, increasing the value of the InBufferSize setting can provide significant improvements in performance.

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

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. In some cases, increasing the value of the OutBufferSize setting can provide significant improvements in performance.

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

Base Config Settings

BuildInfo: Information about the product's build.

When queried, this setting will return a string containing information about the product's build.

GUIAvailable: Whether or not a message loop is available for processing events.

In a GUI-based application, long-running blocking operations may cause the application to stop responding to input until the operation returns. The component will attempt to discover whether or not the application has a message loop and, if one is discovered, it will process events in that message loop during any such blocking operation.

In some non-GUI applications, an invalid message loop may be discovered that will result in errant behavior. In these cases, setting GUIAvailable to false will ensure that the component does not attempt to process external events.

LicenseInfo: Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a component is using. It will return the following information:

Product: The product the license is for.
Product Key: The key the license was generated from.
License Source: Where the license was found (e.g., RuntimeLicense, License File).
License Type: The type of license installed (e.g., Royalty Free, Single Server).
Last Valid Build: The last valid build number for which the license will work.

MaskSensitiveData: Whether sensitive data is masked in log messages.

In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to true to mask sensitive data. The default is true.

This setting only works on these components: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.

UseInternalSecurityAPI: Whether or not to use the system security libraries or an internal implementation.

When set to false, the component will use the system security libraries by default to perform cryptographic functions where applicable. In this case, calls to unmanaged code will be made. In certain environments, this is not desirable. To use a completely managed security implementation, set this setting to true.

Setting this configuration setting to true tells the component to use the internal implementation instead of using the system security libraries.

On Windows, this setting is set to false by default. On Linux/macOS, this setting is set to true by default.

If using the .NET Standard Library, this setting will be true on all platforms. The .NET Standard library does not support using the system security libraries.

Note: This setting is static. The value set is applicable to all components used in the application.

When this value is set, the product's system dynamic link library (DLL) is no longer required as a reference, as all unmanaged code is stored in that file.
