TSYSHCAdjustment Class

Properties Methods Events Config Settings Errors

The TSYSHCAdjustment class is used to adjust a previously authorized transaction. This class makes adjusting transactions very easy.

Syntax

TSYSHCAdjustment

Remarks

This class allows for simple, direct, secure connection to the Vital/TSYS TLS/SSL gateway through a standard Internet connection. This class can be integrated into web pages or stand-alone Point Of Sale applications. Because all TLS/SSL communications are handled inside the class, any application or web page can be deployed without the need for expensive dedicated TLS/SSL servers.

The TSYSHCAdjustment class makes adjusting transactions very easy by adding an additional layer of abstraction between the programmer and the protocol. There is no need to deal with raw sockets, TLS/SSL handshakes, or data packet formatting. The steps to setting up the class and authorizing a transaction are outlined below:

First, set the merchant and POS specific properties with setup information acquired from your member bank or processor. For instance:

TSYSHCAdjustment1.GenKey = "gen_key_value" TSYSHCAdjustment1.MerchantId = "merchant_id" TSYSHCAdjustment1.RoutingId = "routing_id"

Next, set properties that contain details about the transaction. At a minimum, you must set a RetrievalNumber and OriginalAmount.

TSYSHCAdjustment1.RetrievalNumber = TSYSHCRetail1.ResponseRetrievalNumber TSYSHCAdjustment1.OriginalAmount = "1250"

When processing a Level 2 Corporate Purchasing card transaction you need to set the Card properties which will enable the component to send the proper card-specific Level2 fields. For instance:

TSYSHCAdjustment1.Card.MagneticStripe = "%B4444333322221111^SMITH/JOHN J ^031210100000033301000000008000000?" TSYSHCAdjustment1.Card.EntryDataSource = edsTrack1

If you wish to settle an amount that is different than the original authorized amount, you can set SettleAmount to the value you wish to settle. Note that this value can only be less than or equal to the OriginalAmount.

TSYSHCAdjustment1.SettleAmount = "1000"

Finally, submit the adjustment by calling AdjustTransaction. TSYSHCAdjustment1.AdjustTransaction()

When the class receives a response from the Vital/TSYS servers, the result of the adjustment will be displayed in several Response properties. The ResponseCode indicates whether the transaction adjustment was successful. The remaining properties provide additional information about the transaction.

Once the adjustment details are successfully added, the transaction will be added to the current batch. The transaction must go through the batch settlement process in order for the merchant to receive the funds in his merchant account. This is done automatically via a Scheduled Close Batch event that you have setup on your Host Capture Terminal Profile. Alternatively you can manually close a batch by using the TSYSHCBatchMgr class.

Remarks

This property is used to specify the capture mode to be used when performing an authorization or an adjustment transaction.

Possible values are:


Normal (0)	The transaction will be added to the current batch, as specified by BatchNumber, if successfully authorized.
Delay (1)	Indicates that the transaction should not be captured in the current batch without adjustment. If the transaction is adjusted before the current batch closes, then the transaction will be captured in the current batch. If the transaction is not adjusted before the current batch closes, the transaction will be captured in the next batch with or without adjustment.
Hold (2)	When Hold is specified in an original authorization transaction, it will be excluded from batch closing processing.
Capture (3)	When Capture is specified in an adjustment transaction, the batch processing exclusion will be removed in which the transaction will be captured in the current batch.

If you wish to add Level 3 data, you will want to set CaptureMode to Delay (1) when issuing the initial authorization. Then once the Level 3 request is successfully issued, the transaction will be captured in the next batch close event.

Note: To use the Hold and Capture modes, the merchant must be established as a Hold Capture participant.

Note: To use the Delay mode, the merchant must be established as a Delay Capture participant.

int GetSSLCertStoreType();
int SetSSLCertStoreType(int iSSLCertStoreType);

Default Value

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 (PKCS#12) file containing certificates.
3 (cstPFXBlob)	The certificate store is a string (binary or Base64-encoded) representing a certificate store in PFX (PKCS#12) 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.
6 (cstPEMKeyFile)	The certificate store is the name of a PEM-encoded file that contains a private key and an optional certificate.
7 (cstPEMKeyBlob)	The certificate store is a string (binary or Base64-encoded) that contains a private key and an optional certificate.
8 (cstPublicKeyFile)	The certificate store is the name of a file that contains a PEM- or DER-encoded public key certificate.
9 (cstPublicKeyBlob)	The certificate store is a string (binary or Base64-encoded) that contains a PEM- or DER-encoded public key certificate.
10 (cstSSHPublicKeyBlob)	The certificate store is a string (binary or Base64-encoded) that contains an SSH-style public key.
11 (cstP7BFile)	The certificate store is the name of a PKCS#7 file containing certificates.
12 (cstP7BBlob)	The certificate store is a string (binary) representing a certificate store in PKCS#7 format.
13 (cstSSHPublicKeyFile)	The certificate store is the name of a file that contains an SSH-style public key.
14 (cstPPKFile)	The certificate store is the name of a file that contains a PPK (PuTTY Private Key).
15 (cstPPKBlob)	The certificate store is a string (binary) that contains a PPK (PuTTY Private Key).
16 (cstXMLFile)	The certificate store is the name of a file that contains a certificate in XML format.
17 (cstXMLBlob)	The certificate store is a string that contains a certificate in XML format.
18 (cstJWKFile)	The certificate store is the name of a file that contains a JWK (JSON Web Key).
19 (cstJWKBlob)	The certificate store is a string that contains a JWK (JSON Web Key).
21 (cstBCFKSFile)	The certificate store is the name of a file that contains a BCFKS (Bouncy Castle FIPS Key Store). Note: This store type is only available in Java and .NET.
22 (cstBCFKSBlob)	The certificate store is a string (binary or Base64-encoded) representing a certificate store in BCFKS (Bouncy Castle FIPS Key Store) format. Note: This store type is only available in Java and .NET.
23 (cstPKCS11)	The certificate is present on a physical security key accessible via a PKCS#11 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 PKCS#11 DLL. The certificate information returned in the CertList event's `CertEncoded` parameter may be saved for later use. When using a certificate, pass the previously saved security key information as the 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);`
99 (cstAuto)	The store type is automatically detected from the input data. This setting may be used with both public and private keys and can detect any of the supported formats automatically.

Data Type

Integer

SSLCertSubject Property (TSYSHCAdjustment Class)

This is the subject of the certificate used for client authentication.

Syntax

ANSI (Cross Platform)
char* GetSSLCertSubject();
int SetSSLCertSubject(const char* lpszSSLCertSubject);

Unicode (Windows)
LPWSTR GetSSLCertSubject();
INT SetSSLCertSubject(LPCWSTR lpszSSLCertSubject);

char* dpaymentssdk_tsyshcadjustment_getsslcertsubject(void* lpObj);
int dpaymentssdk_tsyshcadjustment_setsslcertsubject(void* lpObj, const char* lpszSSLCertSubject);

QString GetSSLCertSubject();
int SetSSLCertSubject(QString qsSSLCertSubject);

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

SSLProvider Property (TSYSHCAdjustment Class)

This specifies the SSL/TLS implementation to use.

Syntax

ANSI (Cross Platform)
int GetSSLProvider();
int SetSSLProvider(int iSSLProvider);

Unicode (Windows)
INT GetSSLProvider();
INT SetSSLProvider(INT iSSLProvider);

Possible Values

SSLP_AUTOMATIC(0), 
SSLP_PLATFORM(1), 
SSLP_INTERNAL(2)

int dpaymentssdk_tsyshcadjustment_getsslprovider(void* lpObj);
int dpaymentssdk_tsyshcadjustment_setsslprovider(void* lpObj, int iSSLProvider);

int GetSSLProvider();
int SetSSLProvider(int iSSLProvider);

Default Value

Remarks

This property specifies the SSL/TLS implementation to use. In most cases the default value of 0 (Automatic) is recommended and should not be changed. When set to 0 (Automatic) the class 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.

Additional Notes

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

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

Data Type

Integer

SSLServerCertEncoded Property (TSYSHCAdjustment Class)

This is the certificate (PEM/Base64 encoded).

Syntax

ANSI (Cross Platform)
int GetSSLServerCertEncoded(char* &lpSSLServerCertEncoded, int &lenSSLServerCertEncoded);

Unicode (Windows)
INT GetSSLServerCertEncoded(LPSTR &lpSSLServerCertEncoded, INT &lenSSLServerCertEncoded);

int dpaymentssdk_tsyshcadjustment_getsslservercertencoded(void* lpObj, char** lpSSLServerCertEncoded, int* lenSSLServerCertEncoded);

QByteArray GetSSLServerCertEncoded();

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.

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

Data Type

Binary String

Timeout Property (TSYSHCAdjustment Class)

A timeout for the class.

Syntax

ANSI (Cross Platform)
int GetTimeout();
int SetTimeout(int iTimeout);

Unicode (Windows)
INT GetTimeout();
INT SetTimeout(INT iTimeout);

int dpaymentssdk_tsyshcadjustment_gettimeout(void* lpObj);
int dpaymentssdk_tsyshcadjustment_settimeout(void* lpObj, int iTimeout);

int GetTimeout();
int SetTimeout(int iTimeout);

Default Value

Remarks

If Timeout is set to a positive value, and an operation cannot be completed immediately, the class will retry the operation for a maximum of Timeout seconds.

The default value for Timeout is 30 (seconds).

Data Type

Integer

TransactionDesc Property (TSYSHCAdjustment Class)

Soft (Dynamic) Descriptor.

Syntax

ANSI (Cross Platform)
char* GetTransactionDesc();
int SetTransactionDesc(const char* lpszTransactionDesc);

Unicode (Windows)
LPWSTR GetTransactionDesc();
INT SetTransactionDesc(LPCWSTR lpszTransactionDesc);

char* dpaymentssdk_tsyshcadjustment_gettransactiondesc(void* lpObj);
int dpaymentssdk_tsyshcadjustment_settransactiondesc(void* lpObj, const char* lpszTransactionDesc);

QString GetTransactionDesc();
int SetTransactionDesc(QString qsTransactionDesc);

Default Value

Remarks

This property allows a merchant to specify a description about the transaction.

The maximum length of this property is 25 characters (alphanumeric and special characters).

Data Type

String

TransactionNumber Property (TSYSHCAdjustment Class)

Sequence number of this transaction.

Syntax

ANSI (Cross Platform)
int GetTransactionNumber();
int SetTransactionNumber(int iTransactionNumber);

Unicode (Windows)
INT GetTransactionNumber();
INT SetTransactionNumber(INT iTransactionNumber);

int dpaymentssdk_tsyshcadjustment_gettransactionnumber(void* lpObj);
int dpaymentssdk_tsyshcadjustment_settransactionnumber(void* lpObj, int iTransactionNumber);

int GetTransactionNumber();
int SetTransactionNumber(int iTransactionNumber);

Default Value

Remarks

This number must be unique, it's used to identify the transaction in order to operate on it in the future.

This field contains a terminal-generated transaction sequence number to be submitted in all authorization request messages. This number is echoed back to the terminal in the ResponseTransactionNumber for the purpose of assisting in the matching of authorization request and response messages.

The maximum length of this property is 8 characters.

TSYS suggests the following application rules for the format of TransactionNumber:

Format the TransactionNumber as "DDSSS", where DD is the current day of the month and SSS is a sequence of numbers from 001-999.
Configure the sequence number for 2-5 positions so the sequence number can increment through a single day without rolling over.
Allow the sequence to increment and roll-over. Do not program the TransactionNumber to reset when a batch close occurs.

In the case of performing level 3 or settlement transactions, TransactionNumber is not supported and thus RetrievalNumber must be used to reference the transaction.

Data Type

Integer

AdjustTransaction Method (TSYSHCAdjustment Class)

Sends an adjustment request.

Syntax

ANSI (Cross Platform)
int AdjustTransaction();

Unicode (Windows)
INT AdjustTransaction();

int dpaymentssdk_tsyshcadjustment_adjusttransaction(void* lpObj);

int AdjustTransaction();

Remarks

This method allows you to adjust a previously authorized transaction. It can be used to decrease the final SettlementAmount and adjust non-financial fields. If the adjustment request was successful, the ResponseCode property will contain "200". Response will contain additional details about the authorization request.

Minimum required properties:

GenKey
MerchantId
RoutingId
OriginalAmount
RetrievalNumber or TransactionNumber

In the case of performing level 3 or settlement transactions, TransactionNumber is not supported and thus RetrievalNumber must be used to reference the transaction.

If a timeout occurs during the adjustment request, you will want to use the TSYSHCTransactionDetails class to issue a GetDetails request. If the request was received by the TSYS server, the GetDetails response will contain the adjusted values and no other steps are necessary. If the request was not received by the TSYS server, the GetDetails response will show that the adjusted values were not updated. Therefore the adjustment request should be resent.

Note that AdjustTransaction cannot be used to add a tip amount. If you wish to add a tip, you must use AdjustTip.

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.)

Config Method (TSYSHCAdjustment Class)

Sets or retrieves a configuration setting.

Syntax

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

Unicode (Windows)
LPWSTR Config(LPCWSTR lpszConfigurationString);

char* dpaymentssdk_tsyshcadjustment_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 (TSYSHCAdjustment Class)

Interrupts the current action.

Syntax

ANSI (Cross Platform)
int Interrupt();

Unicode (Windows)
INT Interrupt();

int dpaymentssdk_tsyshcadjustment_interrupt(void* lpObj);

int Interrupt();

Remarks

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

Error Handling (C++)

Reset Method (TSYSHCAdjustment Class)

Clears all properties to their default values.

Syntax

ANSI (Cross Platform)
int Reset();

Unicode (Windows)
INT Reset();

int dpaymentssdk_tsyshcadjustment_reset(void* lpObj);

int Reset();

Remarks

This method clears all properties to their default values.

Error Handling (C++)

Error Event (TSYSHCAdjustment Class)

Information about errors during data delivery.

Syntax

ANSI (Cross Platform)
virtual int FireError(TSYSHCAdjustmentErrorEventParams *e);

typedef struct {
  int ErrorCode;
  const char *Description;
  int reserved;
} TSYSHCAdjustmentErrorEventParams;


Unicode (Windows)
virtual INT FireError(TSYSHCAdjustmentErrorEventParams *e);

typedef struct {
  INT ErrorCode;
  LPCWSTR Description;
  INT reserved;
} TSYSHCAdjustmentErrorEventParams;

#define EID_TSYSHCADJUSTMENT_ERROR 1

virtual INT DPAYMENTSSDK_CALL FireError(INT &iErrorCode, LPSTR &lpszDescription);

class TSYSHCAdjustmentErrorEventParams {
public:
  int ErrorCode();

  const QString &Description();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void Error(TSYSHCAdjustmentErrorEventParams *e);

// Or, subclass TSYSHCAdjustment and override this emitter function.
virtual int FireError(TSYSHCAdjustmentErrorEventParams *e) {...}

Remarks

The Error event is fired in case of exceptional conditions during message processing.

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 (TSYSHCAdjustment Class)

Fired after the server presents its certificate to the client.

Syntax

ANSI (Cross Platform)
virtual int FireSSLServerAuthentication(TSYSHCAdjustmentSSLServerAuthenticationEventParams *e);

typedef struct {
  const char *CertEncoded;
  int lenCertEncoded;
  const char *CertSubject;
  const char *CertIssuer;
  const char *Status;
  int Accept;
  int reserved;
} TSYSHCAdjustmentSSLServerAuthenticationEventParams;


Unicode (Windows)
virtual INT FireSSLServerAuthentication(TSYSHCAdjustmentSSLServerAuthenticationEventParams *e);

typedef struct {
  LPCSTR CertEncoded;
  INT lenCertEncoded;
  LPCWSTR CertSubject;
  LPCWSTR CertIssuer;
  LPCWSTR Status;
  BOOL Accept;
  INT reserved;
} TSYSHCAdjustmentSSLServerAuthenticationEventParams;

#define EID_TSYSHCADJUSTMENT_SSLSERVERAUTHENTICATION 2

virtual INT DPAYMENTSSDK_CALL FireSSLServerAuthentication(LPSTR &lpCertEncoded, INT &lenCertEncoded, LPSTR &lpszCertSubject, LPSTR &lpszCertIssuer, LPSTR &lpszStatus, BOOL &bAccept);

class TSYSHCAdjustmentSSLServerAuthenticationEventParams {
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(TSYSHCAdjustmentSSLServerAuthenticationEventParams *e);

// Or, subclass TSYSHCAdjustment and override this emitter function.
virtual int FireSSLServerAuthentication(TSYSHCAdjustmentSSLServerAuthenticationEventParams *e) {...}

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 (TSYSHCAdjustment Class)

Fired when secure connection progress messages are available.

Syntax

ANSI (Cross Platform)
virtual int FireSSLStatus(TSYSHCAdjustmentSSLStatusEventParams *e);

typedef struct {
  const char *Message;
  int reserved;
} TSYSHCAdjustmentSSLStatusEventParams;


Unicode (Windows)
virtual INT FireSSLStatus(TSYSHCAdjustmentSSLStatusEventParams *e);

typedef struct {
  LPCWSTR Message;
  INT reserved;
} TSYSHCAdjustmentSSLStatusEventParams;

#define EID_TSYSHCADJUSTMENT_SSLSTATUS 3

virtual INT DPAYMENTSSDK_CALL FireSSLStatus(LPSTR &lpszMessage);

class TSYSHCAdjustmentSSLStatusEventParams {
public:
  const QString &Message();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void SSLStatus(TSYSHCAdjustmentSSLStatusEventParams *e);

// Or, subclass TSYSHCAdjustment and override this emitter function.
virtual int FireSSLStatus(TSYSHCAdjustmentSSLStatusEventParams *e) {...}

Remarks

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

Config Settings (TSYSHCAdjustment 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.

TSYSHCAdjustment Config Settings

Language: Indicates the language to be used in formatting the authorization response text message.

This field allows you to specify the two-character indicator to indicate the format of the authorization response text message. The current possible values are:


00	English
01	Spanish
02	Portuguese

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.

ServerURL: The server to which transactions are posted.

This is name of the server to which all transactions are posted. Do not use an IP address, use the actual name, as a server's IP address may change. The default (Live) TSYS server is "https://ssl2.vitalps.net/scripts/gateway.dll?transact", but you may use "https://ssltest.tsysacquiring.net/scripts/gateway.dll?transact" for testing.

HTTP Config Settings

AcceptEncoding: Used to tell the server which types of content encodings the client supports.

When AllowHTTPCompression is True, the class adds an Accept-Encoding header to the request being sent to the server. By default, this header's value is "gzip, deflate". This configuration setting allows you to change the value of the Accept-Encoding header. Note: The class only supports gzip and deflate decompression algorithms.

AllowHTTPCompression: This property enables HTTP compression for receiving data.

This configuration setting enables HTTP compression for receiving data. When set to True (default), the class will accept compressed data. It then will uncompress the data it has received. The class will handle data compressed by both gzip and deflate compression algorithms.

When True, the class adds an Accept-Encoding header to the outgoing request. The value for this header can be controlled by the AcceptEncoding configuration setting. The default value for this header is "gzip, deflate".

The default value is True.

AllowHTTPFallback: Whether HTTP/2 connections are permitted to fallback to HTTP/1.1.

This configuration setting controls whether HTTP/2 connections are permitted to fall back to HTTP/1.1 when the server does not support HTTP/2. This setting is applicable only when HTTPVersion is set to "2.0".

If set to True (default), the class will automatically use HTTP/1.1 if the server does not support HTTP/2. If set to False, the class fails with an error if the server does not support HTTP/2.

The default value is True.

Append: Whether to append data to LocalFile.

This configuration setting determines whether data will be appended when writing to LocalFile. When set to True, downloaded data will be appended to LocalFile. This may be used in conjunction with Range to resume a failed download. This is applicable only when LocalFile is set. The default value is False.

Authorization: The Authorization string to be sent to the server.

If the Authorization property contains a nonempty string, an Authorization HTTP request header is added to the request. This header conveys Authorization information to the server.

This property is provided so that the HTTP class can be extended with other security schemes in addition to the authorization schemes already implemented by the class.

The AuthScheme property defines the authentication scheme used. In the case of HTTP Basic Authentication (default), every time User and Password are set, they are Base64 encoded, and the result is put in the Authorization property in the form "Basic [encoded-user-password]".

BytesTransferred: Contains the number of bytes transferred in the response data.

This configuration setting returns the raw number of bytes from the HTTP response data, before the component processes the data, whether it is chunked or compressed. This returns the same value as the Transfer event, by BytesTransferred.

ChunkSize: Specifies the chunk size in bytes when using chunked encoding.

This is applicable only when UseChunkedEncoding is True. This setting specifies the chunk size in bytes to be used when posting data. The default value is 16384.

CompressHTTPRequest: Set to true to compress the body of a PUT or POST request.

If set to True, the body of a PUT or POST request will be compressed into gzip format before sending the request. The "Content-Encoding" header is also added to the outgoing request.

The default value is False.

EncodeURL: If set to True the URL will be encoded by the class.

If set to True, the URL passed to the class will be URL encoded. The default value is False.

FollowRedirects: Determines what happens when the server issues a redirect.

This option determines what happens when the server issues a redirect. Normally, the class returns an error if the server responds with an "Object Moved" message. If this property is set to 1 (always), the new URL for the object is retrieved automatically every time.

If this property is set to 2 (Same Scheme), the new URL is retrieved automatically only if the URL Scheme is the same; otherwise, the class fails with an error.

Note: Following the HTTP specification, unless this option is set to 1 (Always), automatic redirects will be performed only for GET or HEAD requests. Other methods potentially could change the conditions of the initial request and create security vulnerabilities.

Furthermore, if either the new URL server or port are different from the existing one, User and Password are also reset to empty, unless this property is set to 1 (Always), in which case the same credentials are used to connect to the new server.

A Redirect event is fired for every URL the product is redirected to. In the case of automatic redirections, the Redirect event is a good place to set properties related to the new connection (e.g., new authentication parameters).

The default value is 0 (Never). In this case, redirects are never followed, and the class fails with an error instead.

Following are the valid options:

0 - Never
1 - Always
2 - Same Scheme

GetOn302Redirect: If set to True the class will perform a GET on the new location.

The default value is False. If set to True, the class will perform a GET on the new location. Otherwise, it will use the same HTTP method again.

HTTP2HeadersWithoutIndexing: HTTP2 headers that should not update the dynamic header table with incremental indexing.

HTTP/2 servers maintain a dynamic table of headers and values seen over the course of a connection. Typically, these headers are inserted into the table through incremental indexing (also known as HPACK, defined in RFC 7541). To tell the component not to use incremental indexing for certain headers, and thus not update the dynamic table, set this configuration option to a comma-delimited list of the header names.

HTTPVersion: The version of HTTP used by the class.

This property specifies the HTTP version used by the class. Possible values are as follows:

"1.0"
"1.1" (default)
"2.0"
"3.0"

When using HTTP/2 ("2.0"), additional restrictions apply. Please see the following notes for details.

HTTP/2 Notes

When using HTTP/2, a secure Secure Sockets Layer/Transport Layer Security (TLS/SSL) connection is required. Attempting to use a plaintext URL with HTTP/2 will result in an error.

If the server does not support HTTP/2, the class will automatically use HTTP/1.1 instead. This is done to provide compatibility without the need for any additional settings. To see which version was used, check NegotiatedHTTPVersion after calling a method. The AllowHTTPFallback setting controls whether this behavior is allowed (default) or disallowed.

HTTP/3 Notes

HTTP/3 is supported only in .NET and Java.

When using HTTP/3, a secure (TLS/SSL) connection is required. Attempting to use a plaintext URL with HTTP/3 will result in an error.

IfModifiedSince: A date determining the maximum age of the desired document.

If this setting contains a nonempty string, an If-Modified-Since HTTP header is added to the request. The value of this header is used to make the HTTP request conditional: if the requested documented has not been modified since the time specified in the field, a copy of the document will not be returned from the server; instead, a 304 (not modified) response will be returned by the server and the component throws an exception

The format of the date value for IfModifiedSince is detailed in the HTTP specs. For example: Sat, 29 Oct 2017 19:43:31 GMT.

KeepAlive: Determines whether the HTTP connection is closed after completion of the request.

If true, the component will not send the Connection: Close header. The absence of the Connection header indicates to the server that HTTP persistent connections should be used if supported. Note: Not all servers support persistent connections. If false, the connection will be closed immediately after the server response is received.

The default value for KeepAlive is false.

KerberosSPN: The Service Principal Name for the Kerberos Domain Controller.

If the Service Principal Name on the Kerberos Domain Controller is not the same as the URL that you are authenticating to, the Service Principal Name should be set here.

LogLevel: The level of detail that is logged.

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


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

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

The value 2 (Verbose) logs additional information about the request and response.

The value 3 (Debug) logs the headers and body for both the request and response, as well as additional debug information (if any).

MaxRedirectAttempts: Limits the number of redirects that are followed in a request.

When FollowRedirects is set to any value other than frNever, the class will follow redirects until this maximum number of redirect attempts are made. The default value is 20.

NegotiatedHTTPVersion: The negotiated HTTP version.

This configuration setting may be queried after the request is complete to indicate the HTTP version used. When HTTPVersion is set to "2.0" (if the server does not support "2.0"), then the class will fall back to using "1.1" automatically. This setting will indicate which version was used.

OtherHeaders: Other headers as determined by the user (optional).

This configuration setting can be set to a string of headers to be appended to the HTTP request headers.

The headers must follow the format "header: value" as described in the HTTP specifications. Header lines should be separated by CRLF ("\r\n") .

Use this configuration setting with caution. If this configuration setting contains invalid headers, HTTP requests may fail.

This configuration setting is useful for extending the functionality of the class beyond what is provided.

ProxyAuthorization: The authorization string to be sent to the proxy server.

This is similar to the Authorization configuration setting, but is used for proxy authorization. If this configuration setting contains a nonempty string, a Proxy-Authorization HTTP request header is added to the request. This header conveys proxy Authorization information to the server. If ProxyUser and ProxyPassword are specified, this value is calculated using the algorithm specified by ProxyAuthScheme.

ProxyAuthScheme: The authorization scheme to be used for the proxy.

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

ProxyPassword: A password if authentication is to be used for the proxy.

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

ProxyPort: Port for the proxy server (default 80).

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

ProxyServer: Name or IP address of a proxy server (optional).

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

ProxyUser: A user name if authentication is to be used for the proxy.

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

SentHeaders: The full set of headers as sent by the client.

This configuration setting returns the complete set of raw headers as sent by the client.

StatusCode: The status code of the last response from the server.

This configuration setting contains the result code of the last response from the server.

StatusLine: The first line of the last response from the server.

This setting contains the first line of the last response from the server. The format of the line will be [HTTP version] [Result Code] [Description].

TransferredData: The contents of the last response from the server.

This configuration setting contains the contents of the last response from the server.

TransferredDataLimit: The maximum number of incoming bytes to be stored by the class.

If TransferredDataLimit is set to 0 (default), no limits are imposed. Otherwise, this reflects the maximum number of incoming bytes that can be stored by the class.

TransferredHeaders: The full set of headers as received from the server.

This configuration setting returns the complete set of raw headers as received from the server.

TransferredRequest: The full request as sent by the client.

This configuration setting returns the full request as sent by the client. For performance reasons, the request is not normally saved. Set this configuration setting to ON before making a request to enable it. Following are examples of this request:

.NET Http http = new Http(); http.Config("TransferredRequest=on"); http.PostData = "body"; http.Post("http://someserver.com"); Console.WriteLine(http.Config("TransferredRequest")); C++ HTTP http; http.Config("TransferredRequest=on"); http.SetPostData("body", 5); http.Post("http://someserver.com"); printf("%s\r\n", http.Config("TransferredRequest"));

UseChunkedEncoding: Enables or Disables HTTP chunked encoding for transfers.

If UseChunkedEncoding is set to True, the class will use HTTP-chunked encoding when posting, if possible. HTTP-chunked encoding allows large files to be sent in chunks instead of all at once. If set to False, the class will not use HTTP-chunked encoding. The default value is False.

Note: Some servers (such as the ASP.NET Development Server) may not support chunked encoding.

UseIDNs: Whether to encode hostnames to internationalized domain names.

This configuration setting specifies whether hostnames containing non-ASCII characters are encoded to internationalized domain names. When set to True, if a hostname contains non-ASCII characters, it is encoded using Punycode to an IDN (internationalized domain name).

The default value is False and the hostname will always be used exactly as specified. Note: The CodePage setting must be set to a value capable of interpreting the specified host name. For instance, to specify UTF-8, set CodePage to 65001. In the C++ Edition for Windows, the *W version of the class must be used. For instance, DNSW or HTTPW.

UsePlatformHTTPClient: Whether or not to use the platform HTTP client.

When using this configuration setting, if True, the component will use the default HTTP client for the platform (URLConnection in Java, WebRequest in .NET, or CFHTTPMessage in Mac/iOS) instead of the internal HTTP implementation. This is important for environments in which direct access to sockets is limited or not allowed (e.g., in the Google AppEngine).

Note: This setting is applicable only to Mac/iOS editions.

UseProxyAutoConfigURL: Whether to use a Proxy auto-config file when attempting a connection.

This configuration specifies whether the class will attempt to use the Proxy auto-config URL when establishing a connection and ProxyAutoDetect is set to True.

When True (default), the class will check for the existence of a Proxy auto-config URL, and if found, will determine the appropriate proxy to use.

UserAgent: Information about the user agent (browser).

This is the value supplied in the HTTP User-Agent header. The default setting is "IPWorks HTTP Component - www.nsoftware.com".

Override the default with the name and version of your software.

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:


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

Note: This setting is provided for use by 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

..
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:

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:


TLS1.3	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 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.

SSLEnabledProtocols: SSL2 and SSL3 Notes:

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

SSLEnableRenegotiation: Whether the renegotiation_info SSL extension is supported.

This 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:


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

-----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: 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 configuration 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.
