FDMSSettle Class

Properties   Methods   Events   Config Settings   Errors  

The FDMSSettle class is used to do a Batch Settlement on all transactions that were successfully authorized with the FDMSECOMMERCE or FDMSRETAIL classes. This class may also send Level 2 and Level 3 Corporate Purchasing Card data for better interchange rates.

Syntax

FDMSSettle

Remarks

This class connects to the First Data Merchant Services (FDMS) processor, by way of the Datawire VXN transaction transport network. Transactions originating with these classs go through Datawire, to the FDMS processor where the transaction is authorized. The result is then returned back through Datawire and received by the class. This class can be integrated into web pages or stand-alone Point Of Sale applications. Because all SSL communications are handled inside the class, any application or web page can be deployed without the need for expensive dedicated SSL servers.

The FDMSSettle class is used to settle all transactions previously authorized by the FDMSECommerce or FDMSRetail class. When a transaction is authorized, money in the customer's account is blocked and tagged for the merchant. However, funds do not actually change hands at this point. When transactions are settled with the FDMSSettle class the funds are deducted from the customer's account and added to the merchant's. It is essential that the authorized transactions are properly recorded and resent later in a Batch Settlement.

Sending a Batch Settlement with this class is easy. First, you must register and activate your account with Datawire. Datawire will provide you with a MerchantNumber and MerchantTerminalNumber, but you'll need to use the FDMSRegister class to activate the merchant and receive a DatawireId. Once you acquire the DatawireId and receive your transaction URLs through Service Discovery, you may begin to authorize transactions.

To authorize a credit card, set the MerchantNumber and MerchantTerminalNumber with the values supplied by FDMS and Datawire, and the DatawireId with the value retrieved by the FDMSRegister class after activating your merchant account. Set the URL property with one of the URLs you retrieved during Service Discovery.

FDMSSettle.MerchantNumber = "000000999990" 'Supplied by FDMS/Datawire FDMSSettle.MerchantTerminalNumber = "555555" 'Supplied by FDMS/Datawire FDMSSettle.DatawireId = "0000B47FFFFFFFFFFFFF" 'Retrieved with the FDMSRegister class. FDMSSettle.URL = "https://staging1.datawire.net/sd/"; 'Retrieved with the FDMSRegister class.

Additionally, set the IndustryType and the BatchSequenceNumber.

FDMSSettle.IndustryType = fitDirectMarketing FDMSSettle.BatchSequenceNumber = "4127"

At this point, you are ready to add transactions to the batch settlement. Each transaction to be settled must be added to the DetailRecordAggregate array property. First set the DetailRecordCount to the total number of transactions you wish to settle. Each index in the DetailRecordAggregate array property must be set with the XML aggregate returned from the FDMSRetail, FDMSECommerce, or FDMSDetailRecord class's GetDetailAggregate method.

FDMSSettle.DetailRecordCount = 1 FDMSSettle.DetailRecordAggregate(0) = FDMSECommerce.GetDetailAggregate()

Finally, call the SendSettlement method.

FDMSSettle.SendSettlement()

If the settlement is successful, the ResponseBatchStatus will contain "OK" and the ResponseBatchNumber will contain a number which can be used to identify the batch in the future. If the batch was not successful the class fails with an error that indicates the problem. If any individual record in the batch fails, information concerning that record will appear in the Error event when the response to that particular record is received.

Up to 1000 detail records may be settled in the above manner, just by adding transactions to the DetailRecordAggregate property. However, it is recommended that Batch Settlements be kept relatively small - around 100 transactions or so - to decrease the number of records that must be resent in the event of an error.

To void a transaction that has been authorized but has not yet been settled, simply do not include it in the batch settlement. The block on the cardholder's account will clear automatically. If you wish to explicitly void the transaction, use the FDMSDetailRecord class to modify the transaction aggregate and set the TransactionType property to fttVoid. Credits and forced transactions may also be created using the FDMSDetailRecord class and settled in the same manner as regular transactions.

To add Level 2 and Level 3 data to the settled transactions, use the FDMSLevel2 and FDMSLevel3 classs to create addendum aggregates, and then add them to the DetailRecordAddendum for the corresponding transaction stored in DetailRecordAggregate.

Note that the IndustryType from the FDMSSettle class MUST match the detail record aggregate of EACH transaction that is added to the settlement. You cannot mix industry types in a batch - you must settle a separate batch for each industry type.

Remarks

A batch settlement is made up of many separate transaction packets. The class creates these packets and posts them one-by-one to the Datawire VXN, where they are then routed to the FDMS payment processor. Each of these packets sent to Datawire must contain a unique 7 digit transaction sequence identifier. This property should contain the beginning sequence number, which the class will increment for each individual data payload sent in the batch settlement. The component will pad the entered value with trailing zeros as needed and restart at 0 when the maximum transaction sequence identifier is reached.

To retrieve the last transaction sequence identifier used by the component in the batch settlement you need to read the value of BatchSequenceNumber after SendSettlement method is called. ... FDMSSettle.BatchSequenceNumber = "1234"; FDMSSettle.DetailRecords.Add(new FDMSRecordType(FDMSEcommerce.GetDetailAggregate())); FDMSSettle.SendSettlement(); // retrieve the last transaction sequence identifier used in batch settlement // increment it and use in the consecutive transaction to First Data String lastUsedTranNum = FDMSSettle.BatchSequenceNumber; 'this returns the last transaction sequence identifier used in batch settlement.

Remarks

Optional Detail Record Addendum data (such as Level2 or Level3 data)

The DetailRecordDetailAggregate property contains an xml aggregate of the transaction retrieved from the FDMSECommerce, FDMSRetail, or FDMSDetailRecord class's GetDetailAggregate method. If you wish to accept corporate purchasing cards you will also need to send Level2, and possibly Level3 addendum data along with the DetailRecordDetailAggregate. The DetailRecordAddendumAggregate property takes an xml aggregate containing either Level2 or Level2 plus Level3 addendum data, which will be added to the DetailRecordDetailAggregate when sending the settlement. The DetailRecordAddendumAggregate may be created with either the FDMSLevel2 or FDMSLevel3 classs, and then returned via those class's GetAddendum method.

For example:

'First, authorize the credit card FDMSECommerce.TransactionAmount = "2720" '$27.20 FDMSECommerce.Authorize() 'Then, put the result into the settlement component FDMSSettle.DetailRecordCount = 1 FDMSSettle.DetailRecordAggregate(0) = FDMSECommerce.GetDetailAggregate() 'Then build the Level 2 portion FDMSLevel2.CardType = fctVisa FDMSLevel2.CommercialCardType = FDMSECommerce.ResponseCommercialCard FDMSLevel2.OrderDate = "230928" 'September 28th, 2023 FDMSLevel2.FreightTaxAmount = "0" FDMSLevel2.FreightAmount = "600" '$6.00 FDMSLevel2.PurchaseIdentifier = "123456PURCHID" FDMSLevel2.ShippedToZip = "90210" FDMSLevel2.ShippedFromZip = "90210" FDMSLevel2.TaxAmount = "120" '$1.20 'Now build the Level 3 portion FDMSLevel3.CardType = fctVisa FDMSLevel3.LineItemCount = 2 FDMSLevel3.ItemCommodityCode(0) = "4900" ' Books and printed materials FDMSLevel3.ItemDescription(0) = "Reference manual" FDMSLevel3.ItemDiscountAmount(0) = "" ' No discount FDMSLevel3.ItemProductCode(0) = "ISBN123456" FDMSLevel3.ItemTaxAmount(0) = "60" '$0.60 FDMSLevel3.ItemTaxRate(0) = "600" '6.00 percent FDMSLevel3.ItemQuantity(0) = "2" FDMSLevel3.ItemUnitCost(0) = "500" '$5.00 FDMSLevel3.ItemTotal(0) = "1060" '$10.60 FDMSLevel3.ItemUnits(0) = "each" FDMSLevel3.ItemCommodityCode(1) = "4900" ' Books and printed materials FDMSLevel3.ItemDescription(1) = "Quick Start manual" FDMSLevel3.ItemDiscountAmount(1) = "" ' No discount FDMSLevel3.ItemProductCode(1) = "ISBN654321" FDMSLevel3.ItemTaxAmount(1) = "60" '$0.60 FDMSLevel3.ItemTaxRate(1) = "600" '6.00 percent FDMSLevel3.ItemQuantity(1) = "1" FDMSLevel3.ItemUnitCost(1) = "1000" '$10.00 FDMSLevel3.ItemTotal(1) = "1060" '$10.60 FDMSLevel3.ItemUnits(1) = "each" 'Finally, add the Level 2 and Level 3 addendum data to the settlement at the same index 'as the associated transaction. FDMSSettle.DetailRecordAddendum(0) = FDMSLevel2.GetAddendum() & FDMSLevel3.GetAddendum()

Note that you may mix corporate and non-corporate card transactions in the same settlement. It is not necessary that all DetailRecordDetailAggregates have a corresponding DetailRecordAddendumAggregate.

The DetailRecordIndex parameter specifies the index of the item in the array. The size of the array is controlled by the DetailRecordCount property.

This property is not available at design time.

Data Type

String

DetailRecordAggregate Property (FDMSSettle Class)

Set this property with xml aggregates of the transactions you wish to settle.

Syntax

ANSI (Cross Platform)
char* GetDetailRecordAggregate(int iDetailRecordIndex);
int SetDetailRecordAggregate(int iDetailRecordIndex, const char* lpszDetailRecordAggregate); Unicode (Windows) LPWSTR GetDetailRecordAggregate(INT iDetailRecordIndex);
INT SetDetailRecordAggregate(INT iDetailRecordIndex, LPCWSTR lpszDetailRecordAggregate);
char* dpaymentssdk_fdmssettle_getdetailrecordaggregate(void* lpObj, int detailrecordindex);
int dpaymentssdk_fdmssettle_setdetailrecordaggregate(void* lpObj, int detailrecordindex, const char* lpszDetailRecordAggregate);
QString GetDetailRecordAggregate(int iDetailRecordIndex);
int SetDetailRecordAggregate(int iDetailRecordIndex, QString qsDetailRecordAggregate);

Default Value

""

Remarks

Set this property with xml aggregates of the transactions you wish to settle.

To settle previously authorized transactions, this property must be set with the xml aggregate returned from the FDMSECommerce, FDMSRetail, or FDMSDetailRecord class's GetDetailAggregate method. For instance:

FDMSSettle.DetailRecords.Add(new FDMSRecordtype(FDMSRetail1.GetDetailAggregate()));

On occasion, you may need to modify these aggregates before sending them to settlement. For instance, if you're running a restaurant you may need to add a gratuity to the charge. If you're accepting installment payments, you will need to add the installment info. To accomplish this, you may use the FDMSDetailRecord class.

For example, to add a gratuity to a charge:

FDMSDetailRecord.ParseAggregate(FDMSRetail.GetDetailAggregate()) FDMSDetailRecord.Gratuity = "500" FDMSDetailRecord.TransactionAmount = FDMSDetailRecord.TransactionAmount + FDMSDetailRecord.Gratuity FDMSSettle.DetailAggregate(0) = FDMSDetailRecord.GetDetailAggregate()

To settle a transaction authorized with the dmtInstallment TransactionType, you must use the FDMSDetailRecord class to add the number of this installment and the total count of all installments to be made. For instance, if the purchase was for "Three easy payments of $19.95", and this is the first payment, then the installment number will be 1, and the installment count 3. An example is included below:

FDMSECommerce.TransactionType = dmtInstallment FDMSECommerce.TransactionAmount = "1995" FDMSECommerce.Authorize() FDMSDetailRecord.ParseAggregate FDMSECommerce.GetDetailAggregate() FDMSDetailRecord.InstallmentCount = 3 FDMSDetailRecord.InstallmentNumber = 1 FDMSSettle.DetailRecordAggregate(5) = FDMSDetailRecord.GetDetailAggregate()

The DetailRecordIndex parameter specifies the index of the item in the array. The size of the array is controlled by the DetailRecordCount property.

This property is not available at design time.

If ProxyAuthScheme is set to authProprietary (2), then the authorization token will not be generated by the class. Look at the configuration file for the class being used to find more information about manually setting this token.

If ProxyAuthScheme is set to authNtlm (4), NTLM authentication will be used.

For security reasons, setting this property will clear the values of ProxyUser and ProxyPassword.

0

Remarks

This is the type of certificate store for this certificate.

The class supports both public and private keys in a variety of formats. When the cstAuto value is used the class will automatically determine the type. This property can take one of the following values:

0 (cstUser - default)For Windows, this specifies that the certificate store is a certificate store owned by the current user. Note: this store type is not available in Java.
1 (cstMachine)For Windows, this specifies that the certificate store is a machine store. Note: this store type is not available in Java.
2 (cstPFXFile)The certificate store is the name of a PFX (PKCS12) file containing certificates.
3 (cstPFXBlob)The certificate store is a string (binary or base64-encoded) representing a certificate store in PFX (PKCS12) format.
4 (cstJKSFile)The certificate store is the name of a Java Key Store (JKS) file containing certificates. Note: this store type is only available in Java.
5 (cstJKSBlob)The certificate store is a string (binary or base64-encoded) representing a certificate store in Java Key Store (JKS) format. Note: this store type is only available in Java.

23 (cstPKCS11)The certificate is present on a physical security key accessible via a PKCS11 interface.

To use a security key the necessary data must first be collected using the CertMgr class. The ListStoreCertificates method may be called after setting CertStoreType to cstPKCS11, CertStorePassword to the PIN, and CertStore to the full path of the PKCS11 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 SSLCertStore and set SSLCertStorePassword 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);

Once you Register and Activate the merchant using the FDMSRegister class, you may then do a Service Discovery. After sending a Service Discovery transaction, the Datawire system will return a list of transaction URLs. The URL from this list with the shortest round-trip transit time from a ping is the URL you should use here.

Note: By default, this property is populated with the Datawire Staging (test) server, and is not the correct URL to use in a production environment. In a production environment, this URL is supplied by the FDMSRegister class.

Data Type

String

Config Method (FDMSSettle Class)

Sets or retrieves a configuration setting.

Syntax

ANSI (Cross Platform)
char* Config(const char* lpszConfigurationString);

Unicode (Windows)
LPWSTR Config(LPCWSTR lpszConfigurationString);
char* dpaymentssdk_fdmssettle_config(void* lpObj, const char* lpszConfigurationString);
QString Config(const QString& qsConfigurationString);

Remarks

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

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

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.

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

Interrupt Method (FDMSSettle Class)

Interrupts the current action.

Syntax

ANSI (Cross Platform)
int Interrupt();

Unicode (Windows)
INT Interrupt();
int dpaymentssdk_fdmssettle_interrupt(void* lpObj);
int Interrupt();

Remarks

This method interrupts any processing that the class is currently executing.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

Reset Method (FDMSSettle Class)

Clears all properties to their default values.

Syntax

ANSI (Cross Platform)
int Reset();

Unicode (Windows)
INT Reset();
int dpaymentssdk_fdmssettle_reset(void* lpObj);
int Reset();

Remarks

This method clears all properties to their default values.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

SendSettlement Method (FDMSSettle Class)

Begins a Batch Settlement transaction with the transaction server.

Syntax

ANSI (Cross Platform)
int SendSettlement();

Unicode (Windows)
INT SendSettlement();
int dpaymentssdk_fdmssettle_sendsettlement(void* lpObj);
int SendSettlement();

Remarks

This begins a Batch Settlement transaction. The class begins a session with the Datawire system, and then posts a header record, all the detail records, all the Level 2 and Level 3 addendum records (if any), and a trailer record in sequence. The session is then automatically terminated, and the ResponseBatchStatus property will indicate the result of the settlement as returned by the FDMS processor.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

Connected Event (FDMSSettle Class)

This event is fired immediately after a connection completes (or fails).

Syntax

ANSI (Cross Platform)
virtual int FireConnected(FDMSSettleConnectedEventParams *e);
typedef struct {
int StatusCode;
const char *Description; int reserved; } FDMSSettleConnectedEventParams;
Unicode (Windows) virtual INT FireConnected(FDMSSettleConnectedEventParams *e);
typedef struct {
INT StatusCode;
LPCWSTR Description; INT reserved; } FDMSSettleConnectedEventParams;
#define EID_FDMSSETTLE_CONNECTED 1

virtual INT DPAYMENTSSDK_CALL FireConnected(INT &iStatusCode, LPSTR &lpszDescription);
class FDMSSettleConnectedEventParams {

  const QString &Description();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void Connected(FDMSSettleConnectedEventParams *e);
// Or, subclass FDMSSettle and override this emitter function. virtual int FireConnected(FDMSSettleConnectedEventParams *e) {...}

Remarks

If the connection is made normally, StatusCode is 0 and Description is "OK".

If the connection fails, StatusCode has the error code returned by the Transmission Control Protocol (TCP)/IP stack. Description contains a description of this code. The value of StatusCode is equal to the value of the error.

Please refer to the Error Codes section for more information.

DataPacketIn Event (FDMSSettle Class)

Fired when receiving a data packet from the transaction server.

Syntax

ANSI (Cross Platform)
virtual int FireDataPacketIn(FDMSSettleDataPacketInEventParams *e);
typedef struct {
const char *DataPacket; int lenDataPacket; int reserved; } FDMSSettleDataPacketInEventParams;
Unicode (Windows) virtual INT FireDataPacketIn(FDMSSettleDataPacketInEventParams *e);
typedef struct {
LPCSTR DataPacket; INT lenDataPacket; INT reserved; } FDMSSettleDataPacketInEventParams;

// Or, subclass FDMSSettle and override this emitter function. virtual int FireDataPacketIn(FDMSSettleDataPacketInEventParams *e) {...}

Remarks

This event fires when a packet is received. The entire data packet (including all framing and error detection characters) is contained in the parameter "DataPacket". This parameter may be inspected for advanced troubleshooting, or to extract additional response properties beyond the scope of this class.

DataPacketOut Event (FDMSSettle Class)

Fired when sending a data packet to the transaction server.

Syntax

ANSI (Cross Platform)
virtual int FireDataPacketOut(FDMSSettleDataPacketOutEventParams *e);
typedef struct {
const char *DataPacket; int lenDataPacket; int reserved; } FDMSSettleDataPacketOutEventParams;
Unicode (Windows) virtual INT FireDataPacketOut(FDMSSettleDataPacketOutEventParams *e);
typedef struct {
LPCSTR DataPacket; INT lenDataPacket; INT reserved; } FDMSSettleDataPacketOutEventParams;
#define EID_FDMSSETTLE_DATAPACKETOUT 3

  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void DataPacketOut(FDMSSettleDataPacketOutEventParams *e);
// Or, subclass FDMSSettle and override this emitter function. virtual int FireDataPacketOut(FDMSSettleDataPacketOutEventParams *e) {...}

Remarks

This event fires right before each data packet is sent. The entire data packet (including all framing and error detection characters) is contained in the parameter "DataPacket". This parameter may be inspected for advanced troubleshooting, or may be modified to support additional features beyond the scope of this class.

Disconnected Event (FDMSSettle Class)

This event is fired when a connection is closed.

Syntax

ANSI (Cross Platform)
virtual int FireDisconnected(FDMSSettleDisconnectedEventParams *e);
typedef struct {
int StatusCode;
const char *Description; int reserved; } FDMSSettleDisconnectedEventParams;
Unicode (Windows) virtual INT FireDisconnected(FDMSSettleDisconnectedEventParams *e);
typedef struct {
INT StatusCode;
LPCWSTR Description; INT reserved; } FDMSSettleDisconnectedEventParams;
#define EID_FDMSSETTLE_DISCONNECTED 4

virtual INT DPAYMENTSSDK_CALL FireDisconnected(INT &iStatusCode, LPSTR &lpszDescription);
class FDMSSettleDisconnectedEventParams {
public:
  int StatusCode();

  const QString &Description();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void Disconnected(FDMSSettleDisconnectedEventParams *e);
// Or, subclass FDMSSettle and override this emitter function. virtual int FireDisconnected(FDMSSettleDisconnectedEventParams *e) {...}

Remarks

If the connection is broken normally, StatusCode is 0 and Description is "OK".

If the connection is broken for any other reason, StatusCode has the error code returned by the Transmission Control Protocol (TCP/IP) subsystem. Description contains a description of this code. The value of StatusCode is equal to the value of the TCP/IP error.

Please refer to the Error Codes section for more information.

Error Event (FDMSSettle Class)

Information about errors during data delivery.

Syntax

ANSI (Cross Platform)
virtual int FireError(FDMSSettleErrorEventParams *e);
typedef struct {
int ErrorCode;
const char *Description; int reserved; } FDMSSettleErrorEventParams;
Unicode (Windows) virtual INT FireError(FDMSSettleErrorEventParams *e);
typedef struct {
INT ErrorCode;
LPCWSTR Description; INT reserved; } FDMSSettleErrorEventParams;
#define EID_FDMSSETTLE_ERROR 5

virtual INT DPAYMENTSSDK_CALL FireError(INT &iErrorCode, LPSTR &lpszDescription);
class FDMSSettleErrorEventParams {
public:
  int ErrorCode();

  const QString &Description();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void Error(FDMSSettleErrorEventParams *e);
// Or, subclass FDMSSettle and override this emitter function. virtual int FireError(FDMSSettleErrorEventParams *e) {...}

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the class fails with an error.

ErrorCode contains an error code and Description contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

SSLServerAuthentication Event (FDMSSettle Class)

Fired after the server presents its certificate to the client.

Syntax

ANSI (Cross Platform)
virtual int FireSSLServerAuthentication(FDMSSettleSSLServerAuthenticationEventParams *e);
typedef struct {
const char *CertEncoded; int lenCertEncoded;
const char *CertSubject;
const char *CertIssuer;
const char *Status;
int Accept; int reserved; } FDMSSettleSSLServerAuthenticationEventParams;
Unicode (Windows) virtual INT FireSSLServerAuthentication(FDMSSettleSSLServerAuthenticationEventParams *e);
typedef struct {
LPCSTR CertEncoded; INT lenCertEncoded;
LPCWSTR CertSubject;
LPCWSTR CertIssuer;
LPCWSTR Status;
BOOL Accept; INT reserved; } FDMSSettleSSLServerAuthenticationEventParams;
#define EID_FDMSSETTLE_SSLSERVERAUTHENTICATION 6

virtual INT DPAYMENTSSDK_CALL FireSSLServerAuthentication(LPSTR &lpCertEncoded, INT &lenCertEncoded, LPSTR &lpszCertSubject, LPSTR &lpszCertIssuer, LPSTR &lpszStatus, BOOL &bAccept);
class FDMSSettleSSLServerAuthenticationEventParams {
public:
  const QByteArray &CertEncoded();

  const QString &CertSubject();

  const QString &CertIssuer();

  const QString &Status();

  bool Accept();
  void SetAccept(bool bAccept);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void SSLServerAuthentication(FDMSSettleSSLServerAuthenticationEventParams *e);
// Or, subclass FDMSSettle and override this emitter function. virtual int FireSSLServerAuthentication(FDMSSettleSSLServerAuthenticationEventParams *e) {...}

Remarks

This event is where the client can decide whether to continue with the connection process or not. 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 to continue or not.

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 (FDMSSettle Class)

Shows the progress of the secure connection.

Syntax

ANSI (Cross Platform)
virtual int FireSSLStatus(FDMSSettleSSLStatusEventParams *e);
typedef struct {
const char *Message; int reserved; } FDMSSettleSSLStatusEventParams;
Unicode (Windows) virtual INT FireSSLStatus(FDMSSettleSSLStatusEventParams *e);
typedef struct {
LPCWSTR Message; INT reserved; } FDMSSettleSSLStatusEventParams;
#define EID_FDMSSETTLE_SSLSTATUS 7

virtual INT DPAYMENTSSDK_CALL FireSSLStatus(LPSTR &lpszMessage);
class FDMSSettleSSLStatusEventParams {
public:
  const QString &Message();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void SSLStatus(FDMSSettleSSLStatusEventParams *e);
// Or, subclass FDMSSettle and override this emitter function. virtual int FireSSLStatus(FDMSSettleSSLStatusEventParams *e) {...}

Remarks

The event is fired for informational and logging purposes only. Used to track the progress of the connection.

Status Event (FDMSSettle Class)

Shows the progress of the FDMS/Datawire connection.

Syntax

ANSI (Cross Platform)
virtual int FireStatus(FDMSSettleStatusEventParams *e);
typedef struct {
const char *Message; int reserved; } FDMSSettleStatusEventParams;
Unicode (Windows) virtual INT FireStatus(FDMSSettleStatusEventParams *e);
typedef struct {
LPCWSTR Message; INT reserved; } FDMSSettleStatusEventParams;
#define EID_FDMSSETTLE_STATUS 8

virtual INT DPAYMENTSSDK_CALL FireStatus(LPSTR &lpszMessage);
class FDMSSettleStatusEventParams {
public:
  const QString &Message();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void Status(FDMSSettleStatusEventParams *e);
// Or, subclass FDMSSettle and override this emitter function. virtual int FireStatus(FDMSSettleStatusEventParams *e) {...}

Remarks

The event is fired for informational and logging purposes only. Used to track the progress of the connection.

Config Settings (FDMSSettle Class)

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

FDMSSettle Config Settings

ClientTimeout:   Indicates timeout client application will wait for response.

This setting indicates the interval of time, in seconds, a client will wait for the response for any given request. Normally this value is set to a value 5 seconds less than the Timeout value to allow for a response to be received from Datawire. It may be changed independently by setting this configuration setting AFTER setting the Timeout property. Note that too small a value will cause Datawire to reject a transaction immediately.

DetailErrorIndex:   Contains the detail record number that caused the error during settlement.

This field will be populated when an error, caused by a specific detail record, occurs during settlement. This allows you to obtain and review the specific detail record that caused the error. The returned value will need to be adjusted accordingly to obtain the actual index of DetailRecords. For example, if you are using zero-based indexes, a 1 will need to be subtracted from the returned value.

RawRequest:   Returns the request sent to the server for debugging purposes.

After an operation this setting may be queried to return the request as it was sent to the server. This is useful for debugging purposes.

RawResponse:   Returns the response received from the server for debugging purposes.

After an operation this setting may be queried to return the response as it was received from the server. This is useful for debugging purposes.

UseEnhancedSettlement:   Forces enhanced settlement mode.

By default, enhanced settlement is only used when passing Level 2 or Level 3 data in the settlement, or for the Restaurant industry type. Setting this to True will force enhanced settlement mode for all industry types which would normally use the Simple Settlement protocol.

TCPClient Config Settings

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 class will use Timeout for establishing a connection and transmitting/receiving data.

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

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

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 class fails with an error.

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

FirewallType:   Determines the type of firewall to connect through.

The appropriate values are as follows:

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

Note: This setting is provided for use by classs 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 class fails with an error.

Note: This setting is provided for use by classs 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.

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

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 number of times that the keep-alive packets will be sent before the remote host is considered disconnected. The system default if this value is not specified here is 9.

Note: This configuration setting is only available in the Unix platform. It is not supported in masOS or FreeBSD.

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 class 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 multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface.

If the class 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).

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

This must be set before a connection is attempted. It instructs the class 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; 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.

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

By default, this config is set to false.

UseIPv6:   Whether to use IPv6.

When set to 0 (default), the class will use IPv4 exclusively. When set to 1, the class will use IPv6 exclusively. To instruct the class 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:

0 IPv4 Only
1 IPv6 Only
2 IPv6 with IPv4 fallback

SSL Config Settings

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

When SSLProvider is set to Internal, this setting controls whether SSL packets should be logged. By default, this setting is False, as it is only useful 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 setting has no effect if SSLProvider is set to Platform.

OpenSSLCADir:   The path to a directory containing CA certificates.

This functionality is available only when the provider is OpenSSL.

The path set by this property should point to a directory containing CA certificates in PEM format. The files each contain one CA certificate. The files are looked up by the CA subject name hash value, which must hence be available. If more than one CA certificate with the same name hash value exist, the extension must be different (e.g. 9d66eef0.0, 9d66eef0.1 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.

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

This functionality is available only when the provider is OpenSSL.

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

-----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.

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

This functionality is available only when the provider is OpenSSL.

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

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

This functionality is available only when the provider is OpenSSL.

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

ReuseSSLSession:   Determines if the SSL session is reused.

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

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

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

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

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

The default value is:

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

SSLCACerts:   A newline separated list of CA certificate to use during SSL client authentication.

This setting specifies one or more CA certificates to be included in the request when performing SSL client authentication. Some servers require the entire chain, including CA certificates, to be presented when performing SSL client authentication. 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-----

SSLCipherStrength:   The minimum cipher strength used for bulk encryption.

This minimum cipher strength 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.

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.

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

The enabled cipher suites to be used in SSL negotiation.

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

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

Multiple cipher suites are separated by semicolons.

Example values when SSLProvider is set to Platform: 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:

  • CALG_3DES
  • CALG_3DES_112
  • CALG_AES
  • CALG_AES_128
  • CALG_AES_192
  • CALG_AES_256
  • CALG_AGREEDKEY_ANY
  • CALG_CYLINK_MEK
  • CALG_DES

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.

Used to enable/disable the supported security protocols.

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:

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

SSLEnabledProtocols - TLS 1.3 Notes

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

In editions 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.

SSLEnableRenegotiation:   Whether the renegotiation_info SSL extension is supported.

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

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

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

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

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

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

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

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

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

SSLNegotiatedCipher:   Returns the negotiated cipher suite.

Returns the cipher suite negotiated during the SSL handshake.

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

SSLNegotiatedCipherStrength:   Returns the negotiated cipher suite strength.

Returns the strength of the cipher suite negotiated during the SSL handshake.

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

SSLNegotiatedCipherSuite:   Returns the negotiated cipher suite.

Returns the cipher suite negotiated during the SSL handshake represented as a single string.

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

SSLNegotiatedKeyExchange:   Returns the negotiated key exchange algorithm.

Returns the key exchange algorithm negotiated during the SSL handshake.

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

SSLNegotiatedKeyExchangeStrength:   Returns the negotiated key exchange algorithm strength.

Returns the strenghth of the key exchange algorithm negotiated during the SSL handshake.

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

SSLNegotiatedVersion:   Returns the negotiated protocol version.

Returns the protocol version negotiated during the SSL handshake.

Note: For server components (e.g. TCPServer) this is a per-connection 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 or-ed together to exclude multiple conditions:

0x00000001Ignore time validity status of certificate.
0x00000002Ignore time validity status of CTL.
0x00000004Ignore non-nested certificate times.
0x00000010Allow unknown Certificate Authority.
0x00000020Ignore wrong certificate usage.
0x00000100Ignore unknown certificate revocation status.
0x00000200Ignore unknown CTL signer revocation status.
0x00000400Ignore unknown Certificate Authority revocation status.
0x00000800Ignore unknown Root revocation status.
0x00008000Allow test Root certificate.
0x00004000Trust test Root certificate.
0x80000000Ignore non-matching CN (certificate CN not-matching server name).

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

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

This setting optionally specifies one or more CA certificates to be used when 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 setting should only be set 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 setting is a newline (CrLf) separated list of certificates. For instance:

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

d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA
-----END CERTIFICATE-----

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

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

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

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

TLS12SupportedGroups:   The supported groups for ECC.

This 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 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 round trip 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 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:

  • "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 setting holds a comma separated list of allowed signature algorithms. Possible values are:

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

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

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

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

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

Socket Config Settings

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

If AbsoluteTimeout is set to True, any method which 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 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 TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be receiving. Increasing the value of the InBufferSize setting can provide significant improvements in performance in some cases.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the class is activated the InBufferSize reverts to its defined size. The same 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. Increasing the value of the OutBufferSize setting can provide significant improvements in performance in some cases.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the class is activated the OutBufferSize reverts to its defined size. The same 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.

CodePage:   The system code page used for Unicode to Multibyte translations.

The default code page is Unicode UTF-8 (65001).

LicenseInfo:   Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a class 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.
MaskSensitive:   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 classes: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.

ProcessIdleEvents:   Whether the class uses its internal event loop to process events when the main thread is idle.

If set to False, the class will not fire internal idle events. Set this to False to use the class in a background thread on Mac OS. By default, this setting is True.

SelectWaitMillis:   The length of time in milliseconds the class will wait when DoEvents is called if there are no events to process.

If there are no events to process when DoEvents is called, the class will wait for the amount of time specified here before returning. The default value is 20.

UseInternalSecurityAPI:   Tells the class whether or not to use the system security libraries or an internal implementation.

When set to false, the class will use the system security libraries by default to perform cryptographic functions where applicable.

Setting this setting to true tells the class 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.

To use the system security libraries for Linux, OpenSSL support must be enabled. For more information on how to enable OpenSSL, please refer to the OpenSSL Notes section.

Trappable Errors (FDMSSettle Class)

Error Handling (C++)

Call the GetLastErrorCode() method to obtain the last called method's result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. Known error codes are listed below. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.
