SMPP Control
Properties Methods Events Config Settings Errors
The Smpp Control implements a lightweight message transmission interface using the Short Message Peer-to-Peer protocol, most known for its use in cellular text messaging.
Syntax
SMPP
Remarks
The Smpp control supports both plaintext and Secure Sockets Layer/Transport Layer Security (SSL/TLS) connections. When connecting over 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 via the Config method.
The Smpp Control 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 control.
Transmitting messages is just as easy. You can manipulate the Recipients properties 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 Control 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.

Data Type
Integer
SSLCertSubject Property (SMPP Control)
This is the subject of the certificate used for client authentication.
Syntax
smppcontrol.SSLCertSubject[=string]
Default Value
""
Remarks
This is the subject of the certificate used for client authentication.
This property must be set after all other certificate properties are set. When this property is set, a search is performed in the current certificate store to locate a certificate with a matching subject.
If a matching certificate is found, the property is set to the full subject of the matching certificate.
If an exact match is not found, the store is searched for subjects containing the value of the property.
If a match is still not found, the property is set to an empty string, and no certificate is selected.
The special value "*" picks a random certificate in the certificate store.
The certificate subject is a comma-separated list of distinguished name fields and values. For instance, "CN=www.server.com, OU=test, C=US, E=support@nsoftware.com". Common fields and their meanings are as follows:
| Field | Meaning |
| CN | Common Name. This is commonly a hostname like www.server.com. |
| O | Organization |
| OU | Organizational Unit |
| L | Locality |
| S | State |
| C | Country |
| E | Email Address |
If a field value contains a comma, it must be quoted.
Data Type
String
SSLEnabled Property (SMPP Control)
Whether TLS/SSL is enabled.
Syntax
smppcontrol.SSLEnabled[=boolean]
Default Value
False
Remarks
This setting specifies whether TLS/SSL is enabled in the control. When False (default) the control 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.
Data Type
Boolean
SSLProvider Property (SMPP Control)
This specifies the SSL/TLS implementation to use.
Syntax
smppcontrol.SSLProvider[=integer]
Possible Values
sslpAutomatic(0), sslpPlatform(1), sslpInternal(2)
Default Value
0
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 control 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:
| 0 (sslpAutomatic - default) | Automatically selects the appropriate implementation. |
| 1 (sslpPlatform) | Uses the platform/system implementation. |
| 2 (sslpInternal) | Uses the internal implementation. |
In most cases using the default value (Automatic) is recommended. The control will select a provider depending on the current platform.
When Automatic is selected the platform implementation is used by default. When TLS 1.3 is enabled via SSLEnabledProtocols the internal implementation is used.
Data Type
Integer
SSLServerCertEncoded Property (SMPP Control)
This is the certificate (PEM/Base64 encoded).
Syntax
smppcontrol.SSLServerCertEncoded
Default Value
""
Remarks
This is the certificate (PEM/Base64 encoded). This property is used to assign a specific certificate. The SSLServerCertStore and SSLServerCertSubject properties also may be used to specify a certificate.
When SSLServerCertEncoded is set, a search is initiated in the current SSLServerCertStore for the private key of the certificate. If the key is found, SSLServerCertSubject is updated to reflect the full subject of the selected certificate; otherwise, SSLServerCertSubject is set to an empty string.
To read or write binary data to the property, a Variant (Byte Array) version is provided in .SSLServerCertEncodedB.
This property is read-only and not available at design time.
Data Type
Binary String
SSLStartMode Property (SMPP Control)
Determines how the control starts the SSL negotiation.
Syntax
smppcontrol.SSLStartMode[=integer]
Possible Values
sslAutomatic(0), sslImplicit(1), sslExplicit(2), sslNone(3)
Default Value
3
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 control 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 control will first connect in plaintext, and then 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. |
Data Type
Integer
SystemType Property (SMPP Control)
This property contains a string representing the type of system during a connection.
Syntax
smppcontrol.SystemType[=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.
Data Type
String
Timeout Property (SMPP Control)
A timeout for the control.
Syntax
smppcontrol.Timeout[=integer]
Default Value
60
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 control will wait for the operation to complete before returning control.
The control 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 control fails with an error.
Please note that by default, all timeouts are inactivity timeouts, i.e. 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.
Data Type
Integer
UserId Property (SMPP Control)
This property is used for identification with the SMPP service.
Syntax
smppcontrol.UserId[=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.
Data Type
String
AddRecipient Method (SMPP Control)
This method will add a recipient of the specified type to the recipient list.
Syntax
smppcontrol.AddRecipient RecipientType, RecipientAddress
Remarks
This method will add a recipient of the specified type to the recipient list. For normal-type recipients, the addresses should be either a dotted IPv4 address (for sending messages to other SMS-enabled applications) or the directory number of a mobile phone. To send messages to distributed lists, the name of the list should be used.
Valid values for RecipientType are as follows:
| 0 (smppRecipientTypeNormal) | Normal SME (Short Message Entity) Address |
| 1 (smppRecipientTypeList) | Distribution List |
CancelMessage Method (SMPP Control)
This method will cancel the specified message.
Syntax
smppcontrol.CancelMessage MessageId
Remarks
This method will cancel the message stored on the SMPPServer under the value in MessageId.
CheckLink Method (SMPP Control)
This method will check the connection to the server.
Syntax
smppcontrol.CheckLink
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 Control)
This method will retrieve the status of the specified message.
Syntax
smppcontrol.CheckMessageStatus MessageId
Remarks
This method will retrieve the last known status of the message stored on the server under MessageId. The control will fire a MessageStatus containing the parsed response from the server.
Config Method (SMPP Control)
Sets or retrieves a configuration setting.
Syntax
smppcontrol.Config ConfigurationString
Remarks
Config is a generic method available in every control. It is used to set and retrieve configuration settings for the control.
These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the control, 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.
Connect Method (SMPP Control)
This method will bind as a transceiver to the SMPP service.
Syntax
smppcontrol.Connect
Remarks
This method will establish a socket connection to the SMPPServer and attempt to bind as a transceiver. Once the bind operation has been completed, a Connected event will be fired containing the status of the connection.
ConnectTo Method (SMPP Control)
This method will bind as a transceiver to the SMPP service.
Syntax
smppcontrol.ConnectTo UserId, Password
Remarks
This method will establish a socket connection to the SMPPServer and attempt to bind as a transceiver. Once the bind operation has completed, a Connected event will be fired containing the status of the connection.
Disconnect Method (SMPP Control)
This method will disconnect from the SMPP service.
Syntax
smppcontrol.Disconnect
Remarks
This method will send an unbind command and close the socket connection to the SMPPServer. After an unbind operation and socket closing, a Disconnected event will be fired containing the status of the unbind operation.
DoEvents Method (SMPP Control)
This method processes events from the internal message queue.
Syntax
smppcontrol.DoEvents
Remarks
When this method is called, the control processes any available events. If no events are available, it waits for a preset period of time, and then returns.
Interrupt Method (SMPP Control)
Interrupt the current method.
Syntax
smppcontrol.Interrupt
Remarks
If there is no method in progress, Interrupt simply returns, doing nothing.
ReplaceMessage Method (SMPP Control)
This method replaces a previously sent message with a new one.
Syntax
smppcontrol.ReplaceMessage MessageId, NewMessage
Remarks
Assuming that a message on the SMPPServer is being stored under the value in MessageId, this method will replace that message with the value in NewMessage.
If no message corresponds to MessageId, the SMS service will respond with an error message.
Reset Method (SMPP Control)
Reset the control.
Syntax
smppcontrol.Reset
Remarks
This method will reset the control's properties to their default values.
SendCommand Method (SMPP Control)
This method will format and send a protocol data unit (PDU) using the specified command identifier and payload.
Syntax
smppcontrol.SendCommand CommandId, Payload
Remarks
This method offers a way to do more with the control than is directly supported. This method takes a command identifier and a payload, which includes every required and optional field after the header, and creates the 16-byte header for it before sending it to the server. The response PDU is returned both in the PITrail and by this method.
SendData Method (SMPP Control)
This method sends raw data to Recipients .
Syntax
smppcontrol.SendData Data
Remarks
This method sends raw data to Recipients. Up to 64 KB of additional data can be supplied at a time for transmission to the SMPPServer. Unlike the SendMessage method, this method can send to only one destination at a time. The target is whatever value is in the Recipients properties.
SendMessage Method (SMPP Control)
This method sends a message to all recipients in the recipient list.
Syntax
smppcontrol.SendMessage Message
Remarks
This method sends a message to all recipients in the recipient list. The return value of this method is the server-assigned identifier of the message. The maximum size of the message sent is 256 bytes.
Connected Event (SMPP Control)
This event is fired after a successful bind operation.
Syntax
Sub smppcontrol_Connected(StatusCode As Integer, Description As String)
Remarks
After establishing a socket connection to the SMPPServer, the control 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.
ConnectionStatus Event (SMPP Control)
This event is fired to indicate changes in the connection state.
Syntax
Sub smppcontrol_ConnectionStatus(ConnectionEvent As String, StatusCode As Integer, Description As String)
Remarks
The ConnectionStatus event is fired when the connection state changes: for example, completion of a firewall or proxy connection or completion of a security handshake.
The ConnectionEvent parameter indicates the type of connection event. Values may include the following:
| Firewall connection complete. | |
| Secure Sockets Layer (SSL) or S/Shell handshake complete (where applicable). | |
| Remote host connection complete. | |
| Remote host disconnected. | |
| SSL or S/Shell connection broken. | |
| Firewall host disconnected. |
Disconnected Event (SMPP Control)
This event is fired when connection to the SMS service is lost.
Syntax
Sub smppcontrol_Disconnected(StatusCode As Integer, Description As String)
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 Control)
This event is fired when the server detects an error.
Syntax
Sub smppcontrol_Error(ErrorCode As Integer, Description As String)
Remarks
If the server sends an error not related to a command sent from the control, the control 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 Control)
This event is fired upon receipt of a message.
Syntax
Sub smppcontrol_MessageIn(SourceAddress As String, ScheduleDeliveryTime As String, ValidityPeriod As String, Message As String, MessagePart As Integer, MessagePartCount As Integer, MessagePartReference As Integer, DestinationAddress As String, ResponseErrorCode As Integer)
Remarks
When a message is received, the SMPP control 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 Control)
This event is fired upon receipt of a message.
Syntax
Sub smppcontrol_MessageStatus(MessageId As String, MessageState As Integer, MessageError As Integer, FinalDate As String)
Remarks
When a CheckMessageStatus is called, the SMPP control will fetch 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. |
| 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 Control)
This event is fired once for each protocol data unit (PDU) sent between the client and server.
Syntax
Sub smppcontrol_PITrail(Direction As Integer, PDU As String, CommandLength As Integer, CommandId As Integer, CommandDescription As String, CommandStatus As String, SequenceNumber As Integer)
Remarks
Whenever either the control or the SMPPServer sends any data across the connection, the control 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 control 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 Control)
This event is fired when the control is ready to send data.
Syntax
Sub smppcontrol_ReadyToSend()
Remarks
The ReadyToSend event indicates that the underlying Transmission Control Protocol (TCP)/IP subsystem is ready to accept data after a failed DataToSend. This event also is fired immediately after a connection to the remote host is established.
SSLServerAuthentication Event (SMPP Control)
Fired after the server presents its certificate to the client.
Syntax
Sub smppcontrol_SSLServerAuthentication(CertEncoded As String, CertSubject As String, CertIssuer As String, Status As String, Accept As Boolean)
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 Control)
Fired when secure connection progress messages are available.
Syntax
Sub smppcontrol_SSLStatus(Message As String)
Remarks
The event is fired for informational and logging purposes only. This event tracks the progress of the connection.
Config Settings (SMPP Control)
The control 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 control, access to these internal properties is provided through the Config method.SMPP Config Settings
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.
- 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.
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 control does not verify the data in this configuration setting before transmission. After the control 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.

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 control 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.
In multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the control initiate connections (or accept in the case of server controls) only through that interface.
If the control 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 multi-homed hosts (machines with more than one IP interface).
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; setting is useful when trying to connect to services that require a trusted port in the client side. An example is the remote shell (rsh) service in UNIX systems.
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.

SSL Config Settings
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 setting has no effect if SSLProvider is set to Platform.
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 etc). OpenSSL recommends to use the c_rehash utility to create the necessary links. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.
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
-----BEGIN CERTIFICATE-----
... (CA certificate in base64 encoding) ...
-----END CERTIFICATE-----
sequences. Before, between, and after the certificates text is allowed which can be used e.g. for descriptions of the certificates. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.
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".
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.
If set to true, the control 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 control is the same.

When set to 0 (default) the CRL check will not be performed by the control. When set to 1, it will attempt to perform the CRL check, but 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 only supported in the Java, C#, and C++ editions. In the C++ edition, it is only supported on Windows operating systems.
When set to 0 (default) the control will not perform an OCSP check. When set to 1, it will attempt to perform the OCSP check, but 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 only supported in the Java, C#, and C++ editions. In the C++ edition, it is only supported on Windows operating systems.
Please note that this 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 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 config setting.
By default, the enabled cipher suites will include all available ciphers ("*").
The special value "*" means that the control 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:
obj.config("SSLEnabledCipherSuites=*");

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.
Not all supported protocols are enabled by default (the value of this setting is 4032). If you want more granular control over the enabled protocols, you can set this property to the binary 'OR' of one or more of the following values:
| TLS1.3 | 12288 (Hex 3000) |
| TLS1.2 | 3072 (Hex C00) (Default) |
| TLS1.1 | 768 (Hex 300) (Default) |
| TLS1 | 192 (Hex C0) (Default) |
| SSL3 | 48 (Hex 30) [Platform Only] |
| SSL2 | 12 (Hex 0C) [Platform Only] |
SSLEnabledProtocols - TLS 1.3 Notes
By default when TLS 1.3 is enabled the control will use the internal TLS implementation when the SSLProvider is set to Automatic for all editions.
In editions which 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 only supported 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 only available 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 the above 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 control 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.
This setting is only applicable when SSLProvider is set to Internal.
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.
When set, the control 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 traffice for debugging purposes. When writing to this file the control will only append, it will not overwrite previous values.
Note: This setting is only applicable when SSLProvider is set to Internal.

The value of this setting is a newline (CrLf) separated list of certificates. For instance:
-----BEGIN CERTIFICATE----- MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw ... eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w F0I1XhM+pKj7FjDr+XNj -----END CERTIFICATE----- \r \n -----BEGIN CERTIFICATE----- MIIEFjCCAv6gAwIBAgIQetu1SMxpnENAnnOz1P+PtTANBgkqhkiG9w0BAQUFADBp .. d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA -----END CERTIFICATE-----
When specified the control will verify that the server certificate signature algorithm is among the values specified in this setting. If the server certificate signature algorithm is unsupported the control 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 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.
In order to not restrict the server's certificate signature algorithm, specify an empty string as the value for this setting, which will cause the signature_algorithms TLS 1.2 extension to not be sent.
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)
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 setting.
Note: All supported groups can always be used during the handshake even if not listed here, but if a group is used which is not present in this list it will incur an additional round trip and time to generate the key share for that group.
In most cases this setting does not need to be modified. This should only be modified 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:
