AS2Receiver Class

Properties Methods Events Config Settings Errors

The AS2Receiver class is used to process EDI messages and generate receipts.

Syntax

AS2Receiver

Remarks

The AS2Receiver implements server-side processing of EDI messages, as specified in [AS2] and RFC 3335. It can be used to decrypt and verify incoming messages and to generate receipts including Message Disposition Notifications (MDNs). The class is designed to be easily incorporated into an HTTP server, and features custom functionality for server environments such as ASP.NET.

BASIC OPERATION

When an AS2 request comes in, you should first invoke ReadRequest. This will populate AS2From and AS2To, and based on this information, you may then set the appropriate certificates. You may specify your certificate with the Certificate property, and your trading partner's (signing) certificate with the SignerCert property.

Then, invoke ProcessRequest to process the request and generate the MDN receipt as specified in [AS2] and RFC 3335. If the request was processed successfully, EDIData will contain the transmitted EDI data. If a problem occurred, EDIData will not be populated and an exception will be thrown. In either case MDNReceipt will contain the RFC-compliant receipt, which should be returned to the client.

The MDNReceipt may be returned by invoking SendResponse. The receipt will be returned either synchronously in the HTTP reply, or asynchronously over a separate HTTP, HTTPS, or SMTP connection, as requested by the client.

To create log files, set LogDirectory prior to invoking ProcessRequest. This will log all incoming and outgoing data.

The following example illustrates how to use the class from an ASP.NET page. Note that in Java it will be necessary to provide an HTTPServletRequest as an argument to ReadRequest before processing the request.

EXAMPLE AS2Receiver1.ReadRequest(); // At this point, you should check the values of AS2From and AS2To. AS2Receiver1.Certificate = new Certificate(CertStoreTypes.cstPFXFile, "c:\\my_server_directory\\my_pfx_file.pfx", "my password", "CN=Me"); AS2Receiver1.SignerCert = new Certificate("c:\\my_server_directory\\my_partner_cer_file.cer"); AS2Receiver1.LogDirectory = "c:\\my_server_directory\\my_log_directory"; AS2Receiver1.ProcessRequest(); AS2Receiver1.SendResponse(); Additional functionality allows the user to examine details of the client's request, to permit certain types of errors, or to customize the outgoing MDN.

ADVANCED FUNCTIONALITY

Advanced functionality is provided to allow the user to break down the AS2 process, and to allow finer control over the operation of the server. Where ProcessRequest automates the entire process, additional methods are also provided to handle each step separately.

Parsing Incoming Data

To process an EDI message, invoke ReadRequest to process the headers from the server, or alternatively, manually set Request to the contents of the HTTP request. It may contain both headers and body, or the headers may be specified separately in RequestHeaders. This will provide more information about the client's request, without attempting to read the underlying EDI data.

After invoking ReadRequest, the AS2From, AS2To, and MessageId properties will contain the appropriate values. MDNTo will contain a nonempty string if an MDN is requested; RequestedSignatureProtocol, RequestedMICAlgorithms, and ReceiptDeliveryOption provide more information about the client's request. Finally, RequestHeaders contains the complete list of HTTP/AS2 headers.

Next, invoke ParseRequest. The certificate used to decrypt and sign should be specified with the Certificate property, and your partner's signing certificate should be specified with SignerCert. This will process the headers, decompress and/or decrypt the message (if applicable), and verify the signature (if present). EncryptionType, SignatureType, and CompressionFormat describe whether and how the data was encrypted, signed, and compressed, respectively.

ParseRequest will populate EDIType and Data.

Error Handling

If any errors occur an exception will be thrown and EDIData will not be populated. Information about the exception will be provided through the exception's error code and message and also through ScanResult. An MDN receipt reporting the error may still be generated; it is recommended that server software trap the error and invoke CreateMDNReceipt to report the error to the client.

The ErrorProcessingFlags property may be configured to allow predetermined types of errors. If ErrorProcessingFlags is set when ParseRequest (or ProcessRequest) is invoked, the errors specified will be allowed, an exception will not be thrown, and EDIData will still be determined. However, ScanResult will still report the error, as will the receipt generated by CreateMDNReceipt. To avoid reporting the errors in the receipt, set the ErrorReportingFlags property.

Creating an MDN-based Receipt

An MDN-based receipt may be created by invoking CreateMDNReceipt. Regardless of the success or failure of ProcessRequest, the receipt may be created as specified in RFCs 3335 and 2298. If no errors occurred when ProcessRequest was invoked, the receipt will report success and will be suitable for non-repudiation of receipt (NRR) if signed. If errors occurred, the MDN will report that an error occurred and that the EDI data was not processed. It is strongly recommended that server software trap any errors thrown by ProcessRequest and return the receipt in this case as well.

The MDNReceipt will consist of the MDN itself, a human-readable message, MIME headers and footers, and a signature if applicable. The receipt may be generated by invoking CreateMDNReceipt and customized further by setting the parameters to CreateMDNReceipt.

The Message parameter to CreateMDNReceipt may be used to customize the human-readable message in the receipt. If it is set to an empty string, an appropriate message will automatically be written whenever MDNReceipt is regenerated.

The receipt will be signed using the protocol specified by ReceiptSigningProtocol, if any. The certificate used to sign the receipt is specified by Certificate. By default the receipt will be signed if explicitly requested by the client, and unsigned otherwise.

Error reporting may be controlled by configuring ErrorReportingFlags. By default, any errors will cause MDNReceipt to report a failure to process the message (either "failed/Failure" or "processed/Error" will be reported, according to the specification and the type of error). Setting ErrorReportingFlags will cause the MDNReceipt to overlook the chosen types of errors. If all errors are overlooked, the MDNReceipt will report success and calculate a MIC on the original message as usual. A warning may be reported by setting the MDNWarning configuration setting.

Additional Server-Side Functionality

When used in a server environment such as ASP.NET, the class may be used to interface directly with the underlying HTTP context. If Request is not set by the user, ParseRequest and ProcessRequest will first get the request from the underlying HTTP environment, if possible. SendResponse will send the reply in this environment if able; otherwise the reply will be directed to standard out.

ASP.NET Core Notes

The class may be used within any .NET Standard compatible platform, including .NET Core and ASP.NET Core. When using AS2Receiver within an ASP.NET Core MVC application the class can be configured to automatically read from the request context, and send using the response context. To do so pass the HttpContext to the constructor of the AS2Receiver class. For instance:

//Inside HomeController.cs As2receiver as2 = new As2receiver(HttpContext);

Data Type

IPWorksEDIFirewall

IncomingDirectory Property (AS2Receiver Class)

The directory to be used to store incoming messages.

Syntax

ANSI (Cross Platform)
char* GetIncomingDirectory();
int SetIncomingDirectory(const char* lpszIncomingDirectory);

Unicode (Windows)
LPWSTR GetIncomingDirectory();
INT SetIncomingDirectory(LPCWSTR lpszIncomingDirectory);

char* ipworksedi_as2receiver_getincomingdirectory(void* lpObj);
int ipworksedi_as2receiver_setincomingdirectory(void* lpObj, const char* lpszIncomingDirectory);

QString GetIncomingDirectory();
int SetIncomingDirectory(QString qsIncomingDirectory);

Default Value

Remarks

If IncomingDirectory is set, the received message is stored as a file in that directory. If a filename is specified in the EDI message, the class will write to the specified filename, otherwise, a filename will be automatically generated based on a timestamp of the incoming transmission. In either case, if the filename exists on disk, the data will be written to the same name with a "-duplicate?" appended to the filename, where "?" is the number of duplicates.

Please note that the SetTPInfo method, if used, needs to be invoked before setting this property because it overrides the setting for incoming directory.

Data Type

String

LocalHost Property (AS2Receiver Class)

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

Syntax

ANSI (Cross Platform)
char* GetLocalHost();
int SetLocalHost(const char* lpszLocalHost);

Unicode (Windows)
LPWSTR GetLocalHost();
INT SetLocalHost(LPCWSTR lpszLocalHost);

char* ipworksedi_as2receiver_getlocalhost(void* lpObj);
int ipworksedi_as2receiver_setlocalhost(void* lpObj, const char* lpszLocalHost);

QString GetLocalHost();
int SetLocalHost(QString qsLocalHost);

Default Value

Remarks

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

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

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

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

Data Type

String

LogDirectory Property (AS2Receiver Class)

The path to a directory for logging.

Syntax

ANSI (Cross Platform)
char* GetLogDirectory();
int SetLogDirectory(const char* lpszLogDirectory);

Unicode (Windows)
LPWSTR GetLogDirectory();
INT SetLogDirectory(LPCWSTR lpszLogDirectory);

char* ipworksedi_as2receiver_getlogdirectory(void* lpObj);
int ipworksedi_as2receiver_setlogdirectory(void* lpObj, const char* lpszLogDirectory);

QString GetLogDirectory();
int SetLogDirectory(QString qsLogDirectory);

Default Value

Remarks

Setting LogDirectory will instruct the component to log the details of each transmission to unique files in the specified directory. For each request processed, the class will log the complete text of the outgoing request and the incoming response.

The class will write multiple log file for each transmission, with separate extensions for each type of data:


Status (.log)	Contains information on applied security options and pass/fail status of transmission
Request (.req)	Contains the raw incoming request before processing
Payload (.dat)	Contains the EDI payload after processing
MDN Receipt (.mdn)	Contains the MDN receipt prepared by the receiver
Error (.err)	This is only written in an error is encountered, containing the error.

One or more of these logs may be disabled by setting the LogOptions configuration setting.

LogDirectory supports several macros that can be used to specify a unique directory path. If the path specified does not already exist, the class will attempt to create the directory. The following macros are supported:


%MessageID%	The MessageID of the AS2 transmission, after it is generated.
%AS2From%	The AS2-From field in the transmission
%OriginalMessageID%	In MDN Receipts, the MessageID of the transmission that the receipt is for. You can use this to pair asynchronous MDN receipt logs with their transmissions
%Date:Format%	%Format% is a platform-specific date/time formatting string. For example:

The filenames will be chosen automatically by the class. Each filename will be the system time, in the format YYYY-MM-DD-HH-MM-SS-MMMM, with extensions "-2", "-3", used in case files of those names already exist. After each transaction is processed LogFile will contain the name of the files just written, minus the extension.

If logs cannot be written an exception will be thrown.

Data Type

String

LogFile Property (AS2Receiver Class)

The log file written.

Syntax

ANSI (Cross Platform)
char* GetLogFile();

Unicode (Windows)
LPWSTR GetLogFile();

char* ipworksedi_as2receiver_getlogfile(void* lpObj);

QString GetLogFile();

Default Value

Remarks

In case LogDirectory is specified a log file will be written in the specified directory and LogFile will contain the full path and name of the files just written, minus the extension.

The class will write multiple log files for each transmission, with separate extensions for each type of data:


Status (.log)	Contains information on applied security options and pass/fail status of transmission
Request (.req)	Contains the raw incoming request before processing
Payload (.dat)	Contains the EDI payload after processing
MDN Receipt (.mdn)	Contains the MDN receipt prepared by the receiver
Error (.err)	This is only written in an error is encountered, containing the error.

This property is read-only.

Data Type

String

MDNReceipt Property (AS2Receiver Class)

The MDN-based receipt generated by the class.

Syntax

IPWorksEDIMDNReceipt* GetMDNReceipt();
int SetMDNReceipt(IPWorksEDIMDNReceipt* val);

int ipworksedi_as2receiver_getmdnreceiptcontent(void* lpObj, char** lpMDNReceiptContent, int* lenMDNReceiptContent);

QString GetMDNReceiptHeaders();
int SetMDNReceiptHeaders(QString qsMDNReceiptHeaders);

QString GetMDNReceiptHeaderValue();

QString GetMDNReceiptMDN();

QString GetMDNReceiptMessage();

QString GetMDNReceiptMICValue();

QString GetMDNReceiptSigningProtocol();

Remarks

After invoking CreateMDNReceipt, MDNReceipt will contain the entire text of the receipt to be returned to the client. It will report either success or failure depending on ScanResult; in either case it will be RFC-compliant and suitable for returning to the client.

A variety of configuration settings may be used to override the default generation of the outgoing MDN. The MIC algorithm used in the MDN may be set with MDNMICAlgorithm;. MDNReportingUA specifies the reporting agent, and MDNSendingMode may be used to specify the "disposition-mode" field in the MDN.

The signature, if any, will use the protocol specified by the ReceiptSigningProtocol configuration setting, and the certificate specified.

MDNReceipt will always be generated by the component; however, if MDNTo is empty, an MDN-based receipt has not been requested. One may be sent anyway at the option of the server. If MDNTo is nonempty, the receipt MUST be returned according to RFC specifications. In AS2, the MDN should be returned in the body of the HTTP reply, or if ReceiptDeliveryOption is nonempty, to the URL specified there instead. In AS3, the MDN should be returned to the URL specified in MDNTo.

Data Type

IPWorksEDIMDNReceipt

MDNTo Property (AS2Receiver Class)

The recipient for the Message Disposition Notification (MDN).

Syntax

ANSI (Cross Platform)
char* GetMDNTo();

Unicode (Windows)
LPWSTR GetMDNTo();

char* ipworksedi_as2receiver_getmdnto(void* lpObj);

QString GetMDNTo();

Default Value

Remarks

MDNTo corresponds to the Disposition-Notification-To header of RequestHeaders. If nonempty, the client has requested an MDN receipt (typically the actual value is irrelevant). This receipt will be generated in a call to ProcessRequest or CreateMDNReceipt, and may be sent by calling SendResponse.

The receipt will be contained in MDNReceipt. If ReceiptDeliveryOption is empty, the receipt should be synchronously delivered in the HTTP response; otherwise, it should be delivered asynchronously to the URL specified. In either case, SendResponse will send the response as appropriate.

According to RFC specifications, MDNReceipt must be sent if requested by the client. If MDNTo is empty the MDN may be sent or not at the option of the server.

This property is read-only.

Data Type

String

MessageId Property (AS2Receiver Class)

The message ID of the incoming message.

Syntax

ANSI (Cross Platform)
char* GetMessageId();

Unicode (Windows)
LPWSTR GetMessageId();

char* ipworksedi_as2receiver_getmessageid(void* lpObj);

QString GetMessageId();

Default Value

Remarks

MessageId corresponds to the Message-Id header of Request, and will be used as the Original-Message-Id header of MDNReceipt.

This property is read-only.

Data Type

String

ReceiptDeliveryOption Property (AS2Receiver Class)

A URL indicating how the receipt is to be delivered.

Syntax

ANSI (Cross Platform)
char* GetReceiptDeliveryOption();

Unicode (Windows)
LPWSTR GetReceiptDeliveryOption();

char* ipworksedi_as2receiver_getreceiptdeliveryoption(void* lpObj);

QString GetReceiptDeliveryOption();

Default Value

Remarks

This property corresponds to the Receipt-delivery-option header in Request. If nonempty, the client has requested that the receipt be sent to the URL specified asynchronously. If empty, the receipt is to be delivered synchronously in the HTTP reply. In either case the receipt may be delivered by invoking SendResponse.

ReceiptDeliveryOption does not indicate whether or not a receipt was actually requested. If an MDN was requested, that information is given in MDNTo.

This property is read-only.

Data Type

String

Request Property (AS2Receiver Class)

The HTTP request to be processed.

Syntax

ANSI (Cross Platform)
int GetRequest(char* &lpRequest, int &lenRequest);
int SetRequest(const char* lpRequest, int lenRequest);

Unicode (Windows)
INT GetRequest(LPSTR &lpRequest, INT &lenRequest);
INT SetRequest(LPCSTR lpRequest, INT lenRequest);

int ipworksedi_as2receiver_getrequest(void* lpObj, char** lpRequest, int* lenRequest);
int ipworksedi_as2receiver_setrequest(void* lpObj, const char* lpRequest, int lenRequest);

QByteArray GetRequest();
int SetRequest(QByteArray qbaRequest);

Default Value

Remarks

The body of the request to be processed. The HTTP headers may be set separately in RequestHeaders or may be included in Request. If they are included, a double CRLF pair should be used to separate the headers from the body.

When ParseRequest or ProcessRequest is invoked, the contents of Request are lost and you can read the processed data in EDIData.

This property is not available at design time.

Data Type

Binary String

RequestHeaders Property (AS2Receiver Class)

The HTTP headers in the AS2 request.

Syntax

IPWorksEDIList<IPWorksEDIHeader>* GetRequestHeaders();
int SetRequestHeaders(IPWorksEDIList<IPWorksEDIHeader>* val);

int ipworksedi_as2receiver_getrequestheadercount(void* lpObj);
int ipworksedi_as2receiver_setrequestheadercount(void* lpObj, int iRequestHeaderCount);

char* ipworksedi_as2receiver_getrequestheaderfield(void* lpObj, int requestheaderindex);
int ipworksedi_as2receiver_setrequestheaderfield(void* lpObj, int requestheaderindex, const char* lpszRequestHeaderField);

char* ipworksedi_as2receiver_getrequestheadervalue(void* lpObj, int requestheaderindex);
int ipworksedi_as2receiver_setrequestheadervalue(void* lpObj, int requestheaderindex, const char* lpszRequestHeaderValue);

int GetRequestHeaderCount();
int SetRequestHeaderCount(int iRequestHeaderCount);

QString GetRequestHeaderField(int iRequestHeaderIndex);
int SetRequestHeaderField(int iRequestHeaderIndex, QString qsRequestHeaderField);

QString GetRequestHeaderValue(int iRequestHeaderIndex);
int SetRequestHeaderValue(int iRequestHeaderIndex, QString qsRequestHeaderValue);

Remarks

A collection of headers. These will include AS2-specific headers as well as general HTTP headers.

When assigning an AS2 request to the class, the headers may be included in Request or specified separately in RequestHeaders. If the headers are included in Request they will be parsed out whenever ReadRequest, ParseRequest, or ProcessRequest is invoked.

Data Type

IPWorksEDIHeader

RequestHeadersString Property (AS2Receiver Class)

The HTTP headers in the AS2 request.

Syntax

ANSI (Cross Platform)
char* GetRequestHeadersString();
int SetRequestHeadersString(const char* lpszRequestHeadersString);

Unicode (Windows)
LPWSTR GetRequestHeadersString();
INT SetRequestHeadersString(LPCWSTR lpszRequestHeadersString);

char* ipworksedi_as2receiver_getrequestheadersstring(void* lpObj);
int ipworksedi_as2receiver_setrequestheadersstring(void* lpObj, const char* lpszRequestHeadersString);

QString GetRequestHeadersString();
int SetRequestHeadersString(QString qsRequestHeadersString);

Default Value

Remarks

The entire list of headers, concatenated into a single string. These will include AS2- specific headers as well as general HTTP headers. You may access specific headers through RequestHeaders.

Data Type

String

RestartDirectory Property (AS2Receiver Class)

The directory to log cached files when using AS2 restart functionality.

Syntax

ANSI (Cross Platform)
char* GetRestartDirectory();
int SetRestartDirectory(const char* lpszRestartDirectory);

Unicode (Windows)
LPWSTR GetRestartDirectory();
INT SetRestartDirectory(LPCWSTR lpszRestartDirectory);

char* ipworksedi_as2receiver_getrestartdirectory(void* lpObj);
int ipworksedi_as2receiver_setrestartdirectory(void* lpObj, const char* lpszRestartDirectory);

QString GetRestartDirectory();
int SetRestartDirectory(QString qsRestartDirectory);

Default Value

Remarks

If this property is set, the class will cache all received files to the RestartDirectory. Thus, when receiving a file is interrupted, the client can restart the transmission of the file starting where it was interrupted.

To use this functionality, HTTP HEAD requests must be processed using the ProcessRestartRequest method.

When using restart functionality, the data is processed after the entire file contents are received.

NOTE: This directory will not automatically be cleaned up.

Data Type

String

RolloverCertificate Property (AS2Receiver Class)

The rollover decryption and receipt signing certificate.

Syntax

IPWorksEDICertificate* GetRolloverCertificate();
int SetRolloverCertificate(IPWorksEDICertificate* val);

int ipworksedi_as2receiver_getrollovercertstore(void* lpObj, char** lpRolloverCertStore, int* lenRolloverCertStore);
int ipworksedi_as2receiver_setrollovercertstore(void* lpObj, const char* lpRolloverCertStore, int lenRolloverCertStore);

char* ipworksedi_as2receiver_getrollovercertstorepassword(void* lpObj);
int ipworksedi_as2receiver_setrollovercertstorepassword(void* lpObj, const char* lpszRolloverCertStorePassword);

int ipworksedi_as2receiver_getrollovercertstoretype(void* lpObj);

int ipworksedi_as2receiver_getrollovercertencoded(void* lpObj, char** lpRolloverCertEncoded, int* lenRolloverCertEncoded);
int ipworksedi_as2receiver_setrollovercertencoded(void* lpObj, const char* lpRolloverCertEncoded, int lenRolloverCertEncoded);

QByteArray GetRolloverCertStore();
int SetRolloverCertStore(QByteArray qbaRolloverCertStore);

QString GetRolloverCertStorePassword();
int SetRolloverCertStorePassword(QString qsRolloverCertStorePassword);

int GetRolloverCertStoreType();
int SetRolloverCertStoreType(int iRolloverCertStoreType);

QString GetRolloverCertSubject();
int SetRolloverCertSubject(QString qsRolloverCertSubject);

QByteArray GetRolloverCertEncoded();
int SetRolloverCertEncoded(QByteArray qbaRolloverCertEncoded);

Remarks

The rollover digital certificate that the class will use to decrypt incoming transmissions and sign the MDN receipt (if requested). This may be used to specify an additional decryption and receipt signing certificate during a period of transition between private certificates in the application.

When specified the class will be able to decrypt messages that were encrypted with the corresponding public certificate of either Certificate or RolloverCertificate. MDNs will be signed with both the certificate in Certificate and RolloverCertificate.

If a different certificate is required for decryption than for MDN signing, set the decryption certificate before calling ParseRequest, then set the rollover signing certificate before calling CreateMDNReceipt. RolloverCertificate must be set to a private key certificate.

Data Type

IPWorksEDICertificate

ScanResult Property (AS2Receiver Class)

The result of invoking ParseRequest .

Syntax

ANSI (Cross Platform)
int GetScanResult();

Unicode (Windows)
INT GetScanResult();

int ipworksedi_as2receiver_getscanresult(void* lpObj);

int GetScanResult();

Default Value

Remarks

ScanResult will contain information about any errors that occurred while invoking ParseRequest or ProcessRequest. ScanResult will contain 0 if no errors occurred, otherwise it will contain one or more of the following errors. If multiple errors are reported the results will be OR-ed together.


0x01	Unable to decrypt data.
0x02	Unable to decompress data.
0x04	Unable to validate integrity of data.
0x08	Unable to verify the signature.
0x10	Client requested unsupported signature type.
0x20	Client requested unsupported MIC algorithm.
0x40	Insufficient message security, as determined by the Config entries RequireSign and RequireEncrypt.
0x80	Unexpected processing error. An exception was encountered outside of message processing, such as configuration issues in the class.
0x100	Duplicate filename.
0x200	Illegal filename.
0x400	Empty filename.
0x800	Error writing incoming file.

This property is read-only.

char* ipworksedi_as2receiver_getsignercertsubject(void* lpObj);
int ipworksedi_as2receiver_setsignercertsubject(void* lpObj, const char* lpszSignerCertSubject);

int ipworksedi_as2receiver_getsignercertencoded(void* lpObj, char** lpSignerCertEncoded, int* lenSignerCertEncoded);
int ipworksedi_as2receiver_setsignercertencoded(void* lpObj, const char* lpSignerCertEncoded, int lenSignerCertEncoded);

QByteArray GetSignerCertStore();
int SetSignerCertStore(QByteArray qbaSignerCertStore);

QString GetSignerCertStorePassword();
int SetSignerCertStorePassword(QString qsSignerCertStorePassword);

int GetSignerCertStoreType();
int SetSignerCertStoreType(int iSignerCertStoreType);

QString GetSignerCertSubject();
int SetSignerCertSubject(QString qsSignerCertSubject);

QByteArray GetSignerCertEncoded();
int SetSignerCertEncoded(QByteArray qbaSignerCertEncoded);

Remarks

You must set your trading partner's certificate before processing any signed messages. This property should be set to a public key certificate.

If the trading partner's identity is unknown, you should first invoke ReadRequest and read the value of AS2To (or for AS3, AS3To). This will allow you to determine the correct certificate to use.

As a special case, you may set AcceptAnySignerCert to true. In this case, the class will attempt to validate the signature without knowing the certificate in advance. This is not recommended for production use, as it poses a security risk.

This property is not available at design time.

Data Type

IPWorksEDICertificate

SSLAcceptServerCert Property (AS2Receiver Class)

For sending HTTPS asynchronous MDNs, a server certificate to unconditionally accept.

Syntax

IPWorksEDICertificate* GetSSLAcceptServerCert();
int SetSSLAcceptServerCert(IPWorksEDICertificate* val);

int ipworksedi_as2receiver_getsslacceptservercertstore(void* lpObj, char** lpSSLAcceptServerCertStore, int* lenSSLAcceptServerCertStore);

int SetSSLAcceptServerCertSubject(QString qsSSLAcceptServerCertSubject);

QByteArray GetSSLAcceptServerCertEncoded();
int SetSSLAcceptServerCertEncoded(QByteArray qbaSSLAcceptServerCertEncoded);

Remarks

You must set this property to send asynchronous HTTPS MDNs if your trading partner is using a certificate that is not inherently trusted by your system.

When an asynchronous MDN is requested over HTTPS, the class will create a new secure connection with the URL specified in ReceiptDeliveryOption. By default the class will reject any server certificates not signed by a trusted Certificate Authority (CA).

You may also trap the SSLServerAuthentication event to accept the server certificate.

Data Type

IPWorksEDICertificate

SSLCert Property (AS2Receiver Class)

The certificate used for client authentication.

Syntax

IPWorksEDICertificate* GetSSLCert();
int SetSSLCert(IPWorksEDICertificate* val);

Remarks

SSLCert is used for specifying a private key certificate for HTTP client authentication.

Data Type

IPWorksEDICertificate

UsePSS Property (AS2Receiver Class)

This property specifies whether or not RSA-PSS will be used during signing and verification.

Syntax

ANSI (Cross Platform)
int GetUsePSS();
int SetUsePSS(int bUsePSS);

Unicode (Windows)
BOOL GetUsePSS();
INT SetUsePSS(BOOL bUsePSS);

int ipworksedi_as2receiver_getusepss(void* lpObj);
int ipworksedi_as2receiver_setusepss(void* lpObj, int bUsePSS);

bool GetUsePSS();
int SetUsePSS(bool bUsePSS);

Default Value

FALSE

Remarks

This property specifies whether or not RSA-PSS will be used when signing and verifying messages. The default value is False.

Data Type

Boolean

AckRequest Method (AS2Receiver Class)

Optional. Acknowledges the incoming request.

Syntax

ANSI (Cross Platform)
int AckRequest();

Unicode (Windows)
INT AckRequest();

int ipworksedi_as2receiver_ackrequest(void* lpObj);

int AckRequest();

Remarks

When called from within a server environment, AckRequest will acknowledge the client request with a 200 OK. This may be useful if the client has posted a lot of data, and has requested an asynchronous receipt.

If an acknowledgement is not expected (i.e., the client is expecting an MDN in the response), then invoking this method will do nothing. Servers may safely call this method immediately after ParseRequest for both synchronous and asynchronous MDN requests.

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 (AS2Receiver Class)

Sets or retrieves a configuration setting.

Syntax

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

Unicode (Windows)
LPWSTR Config(LPCWSTR lpszConfigurationString);

char* ipworksedi_as2receiver_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.

CreateMDNReceipt Method (AS2Receiver Class)

Creates MDNReceipt .

Syntax

ANSI (Cross Platform)
int CreateMDNReceipt(const char* lpszHeaders, const char* lpszMDN, const char* lpszMessage);

Unicode (Windows)
INT CreateMDNReceipt(LPCWSTR lpszHeaders, LPCWSTR lpszMDN, LPCWSTR lpszMessage);

int ipworksedi_as2receiver_createmdnreceipt(void* lpObj, const char* lpszHeaders, const char* lpszMDN, const char* lpszMessage);

int CreateMDNReceipt(const QString& qsHeaders, const QString& qsMDN, const QString& qsMessage);

Remarks

CreateMDNReceipt may be invoked after ParseRequest to create an MDN-based receipt. The receipt will report success or failure depending on ErrorReportingFlags and the success or failure of ParseRequest.

This method populates MDNReceipt with a new MDNReceipt. The Headers, MDN, and Message parameters can be used to further customize the receipt, or empty string ("") parameters may be set to use the class generated defaults. Headers will set additional transport headers to be sent with the receipt (in the HTTP or SMTP headers of the signed receipt). MDN can be used to append additional headers to the Message Disposition Notification portion of the MDN Receipt. If MDN is set to a value prefixed with an at sign ("@"), the at sign will be removed and the specified MDN will be used in the receipt in place of the component generated value. Message will set the human-readable portion of the receipt, and should describe any error conditions that may have occurred.

Error Handling (C++)

ParseRequest Method (AS2Receiver Class)

Parses the EDI message and determines the EDIData .

Syntax

ANSI (Cross Platform)
int ParseRequest();

Unicode (Windows)
INT ParseRequest();

int ipworksedi_as2receiver_parserequest(void* lpObj);

int ParseRequest();

Remarks

Processes the EDI message in the request (either from the HTTP context, or as given by Request and possibly RequestHeadersString). If the message is encrypted, it will be decrypted with the certificate specified in Certificate. If it is signed, the signature will be verified against the certificate specified in SignerCert.

If the message is scanned without difficulty, EDIData will be populated. If a problem occurs, an exception will be thrown. This might occur if the client used or requested unsupported algorithms or data formats. In this case, EDIData will not be determined.

The class may be configured to ignore certain errors by setting ErrorProcessingFlags. This will allow the message to be processed and EDIData to be determined. If any errors occur, an exception will be thrown and the ScanResult property will reflect the error condition.

Whether or not an exception is thrown, an MDNReceipt may be generated by invoking CreateMDNReceipt. In the case of a successful scan MDNReceipt will report the success, otherwise the receipt will provide information to the client about the error.

ProcessRequest may be used to scan and create the receipt in one step. ReadRequest may be used to scan the request headers only to obtain details that can be used to configure the correct settings for the partner.

Error Handling (C++)

ProcessRequest Method (AS2Receiver Class)

Processes the EDI data, and generates the receipt.

Syntax

ANSI (Cross Platform)
int ProcessRequest();

Unicode (Windows)
INT ProcessRequest();

int ipworksedi_as2receiver_processrequest(void* lpObj);

int ProcessRequest();

Remarks

Invoking ProcessRequest automates the entire AS2 server process. The method scans the request, determines the EDIData, and generates the MDNReceipt. In a server environment the receipt may be returned by invoking SendResponse.

The method's functionality is the same as the combined functionality of ParseRequest and CreateMDNReceipt. The method's operation is controlled by ErrorProcessingFlags and ErrorReportingFlags, and ScanResult will be populated as in ParseRequest.

The method will throw an exception, as ParseRequest does, if a problem is found while processing the request. However, if the problem does not prevent an MDN from being generated, MDNReceipt will still be generated before the exception is thrown. In all cases, the receipt will be suitable for returning to the client. If an exception is thrown, the MDNReceipt will provide more detail on the cause of the error.

The class will populate EDIData if no errors occurred scanning the request, or if ErrorProcessingFlags had been previously configured to allow the error.

Error Handling (C++)

ProcessRestartRequest Method (AS2Receiver Class)

Processes the AS2 restart request, and sends a response to the client.

Syntax

ANSI (Cross Platform)
int ProcessRestartRequest();

Unicode (Windows)
INT ProcessRestartRequest();

int ipworksedi_as2receiver_processrestartrequest(void* lpObj);

int ProcessRestartRequest();

Remarks

Invoking ProcessRestartRequest automates the restart AS2 server process. The method should be invoked when the HTTP HEAD request is received. The class will then parse the request, and respond to the client with the number of bytes (if any) the class received during a previous connection. The class will look for unfinished files in the RestartDirectory when processing these requests.

Error Handling (C++)

ReadRequest Method (AS2Receiver Class)

Reads the AS2 request from the HTTP session.

Syntax

ANSI (Cross Platform)
int ReadRequest();

Unicode (Windows)
INT ReadRequest();

int ipworksedi_as2receiver_readrequest(void* lpObj);

int ReadRequest();

Remarks

ReadRequest reads the AS2 request from the content of the Request (and optionally the RequestHeadersString) property. The class will parse the request from Request. The headers will be read into RequestHeaders. Finally, the class will parse the headers and populate the following properties:

AS2From
AS2To
AS2VersionIncoming
MessageId
MDNTo
ReceiptDeliveryOption
RequestedSignatureProtocol
RequestedMICAlgorithms

ParseRequest may be used to scan the entire message.

Error Handling (C++)

Reset Method (AS2Receiver Class)

Resets the state of the control.

Syntax

ANSI (Cross Platform)
int Reset();

Unicode (Windows)
INT Reset();

int ipworksedi_as2receiver_reset(void* lpObj);

int Reset();

Remarks

Reset resets the state of the class. All properties will be set to their default values.

Error Handling (C++)

SendAsyncMDN Method (AS2Receiver Class)

Sends the MDNReceipt to the RemoteURL specified.

Syntax

ANSI (Cross Platform)
int SendAsyncMDN(const char* lpszRemoteURL, const char* lpMDNReceipt, int lenMDNReceipt, const char* lpszMDNReceiptHeaders);

Unicode (Windows)
INT SendAsyncMDN(LPCWSTR lpszRemoteURL, LPCSTR lpMDNReceipt, INT lenMDNReceipt, LPCWSTR lpszMDNReceiptHeaders);

int ipworksedi_as2receiver_sendasyncmdn(void* lpObj, const char* lpszRemoteURL, const char* lpMDNReceipt, int lenMDNReceipt, const char* lpszMDNReceiptHeaders);

int SendAsyncMDN(const QString& qsRemoteURL, QByteArray qbaMDNReceipt, const QString& qsMDNReceiptHeaders);

Remarks

This method sends the asynchronous MDNReceipt to the RemoteURL specified. It need not be invoked if the prior call to SendResponse was successful. The RemoteURL, MDNReceipt, and MDNReceiptHeaders parameters should be the ones that were retrieved from ReceiptDeliveryOption and MDNReceipt's Content and Headers properties respectively.

If the RemoteURL requires SMTP transfer, the appropriate SMTP settings should be set using Config.

Error Handling (C++)

SendResponse Method (AS2Receiver Class)

In a server environment, responds to the requesting client with MDNReceipt .

Syntax

ANSI (Cross Platform)
int SendResponse();

Unicode (Windows)
INT SendResponse();

int ipworksedi_as2receiver_sendresponse(void* lpObj);

int SendResponse();

Remarks

When called from within a server environment, SendResponse will respond to the requesting client. If an MDN was requested, then MDNReceipt will be returned to the client, either in the HTTP response or in a separate transmission, depending on the client request. In case it is returned in a separate transmission, a simple acknowledgement of "200 OK" will also be sent in the HTTP response, unless this was sent previously using AckRequest.

The AS2 headers will be taken from MDNReceipt and will be merged with HTTP headers as appropriate. Note that if ReceiptDeliveryOption indicates a "mailto:" URL, the appropriate SMTP settings should be set using Config.

The exact behavior of the method is specific to the environment. . Otherwise, the receipt will be directed to stdout. If this is impossible, an exception will be thrown.

Optionally, if an asynchronous MDN is requested, the MDNReceipt and ReceiptDeliveryOption may be saved so that the MDN may be sent later through the SendAsyncMDN method.

This method should only be invoked after MDNReceipt has been generated by CreateMDNReceipt or ProcessRequest.

Error Handling (C++)

SetTPInfo Method (AS2Receiver Class)

A convenient way to set AS2 communication parameters using XML strings.

Syntax

ANSI (Cross Platform)
int SetTPInfo(const char* lpszProfile);

Unicode (Windows)
INT SetTPInfo(LPCWSTR lpszProfile);

int ipworksedi_as2receiver_settpinfo(void* lpObj, const char* lpszProfile);

int SetTPInfo(const QString& qsProfile);

Remarks

SetTPInfo offers a convenient way to set AS2 communication parameters using XML strings. The format of the XML is the same as provided by the method GetTPInfo of AS2ProfileMgr.

An example usage scenario is shown below. AS2Receiver as2receiver = new AS2Receiver(); AS2Profilemgr mgr = new AS2Profilemgr(); mgr.DataDir = "C:\as2data"; as2receiver.setTPInfo(mgr.getTPInfo("self")); as2receiver.readRequest(); as2sender.setTPInfo(mgr.getTPInfo(as2receiver.getAS2From())); as2receiver.processRequest(); as2receiver.sendResponse();

Error Handling (C++)

CEMRequest Event (AS2Receiver Class)

Fired when a Certificate Exchange Messaging (CEM) request is received.

Syntax

ANSI (Cross Platform)
virtual int FireCEMRequest(AS2ReceiverCEMRequestEventParams *e);

typedef struct {
  const char *RequestId;
  const char *As2From;
  int reserved;
} AS2ReceiverCEMRequestEventParams;


Unicode (Windows)
virtual INT FireCEMRequest(AS2ReceiverCEMRequestEventParams *e);

typedef struct {
  LPCWSTR RequestId;
  LPCWSTR As2From;
  INT reserved;
} AS2ReceiverCEMRequestEventParams;

#define EID_AS2RECEIVER_CEMREQUEST 1

virtual INT IPWORKSEDI_CALL FireCEMRequest(LPSTR &lpszRequestId, LPSTR &lpszAs2From);

class AS2ReceiverCEMRequestEventParams {
public:
  const QString &RequestId();

  const QString &As2From();

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

// To handle, connect one or more slots to this signal.
void CEMRequest(AS2ReceiverCEMRequestEventParams *e);

// Or, subclass AS2Receiver and override this emitter function.
virtual int FireCEMRequest(AS2ReceiverCEMRequestEventParams *e) {...}

Remarks

This event fires when a Certificate Exchange Messaging (CEM) request is received.

RequestId is the CEM request Id. This must be saved and will be used when sending the CEM response.

As2From identifies the sender of the CEM request.

If CEMCertDir is set the received certificates will be written to the specified location. If CEMCertDir is not set the certificates will be held in memory and may be accessed by inspecting CEMDetails.

The CEM request also populates RespondByDate and ResponseURL. RespondByDate specifies the date by which the sender expects a response. ResponseURL specifies the URL to which the CEM response should be sent.

When this event fires the following CEMDetails fields are applicable:

CertStoreType
CertStore
CertSubject
CertUsage
CertIssuer
CertSerialNumber
CertId
RespondByDate
ResponseURL

To send a CEM response save the CEMDetails values and call SendCEMResponse with the AS2Sender class.

CEMResponse Event (AS2Receiver Class)

Fired when a Certificate Exchange Messaging (CEM) response is received.

Syntax

ANSI (Cross Platform)
virtual int FireCEMResponse(AS2ReceiverCEMResponseEventParams *e);

typedef struct {
  const char *RequestId;
  const char *As2From;
  int reserved;
} AS2ReceiverCEMResponseEventParams;


Unicode (Windows)
virtual INT FireCEMResponse(AS2ReceiverCEMResponseEventParams *e);

typedef struct {
  LPCWSTR RequestId;
  LPCWSTR As2From;
  INT reserved;
} AS2ReceiverCEMResponseEventParams;

#define EID_AS2RECEIVER_CEMRESPONSE 2

virtual INT IPWORKSEDI_CALL FireCEMResponse(LPSTR &lpszRequestId, LPSTR &lpszAs2From);

class AS2ReceiverCEMResponseEventParams {
public:
  const QString &RequestId();

  const QString &As2From();

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

// To handle, connect one or more slots to this signal.
void CEMResponse(AS2ReceiverCEMResponseEventParams *e);

// Or, subclass AS2Receiver and override this emitter function.
virtual int FireCEMResponse(AS2ReceiverCEMResponseEventParams *e) {...}

Remarks

This event fires when a Certificate Exchange Messaging (CEM) response is received.

RequestId is the CEM request Id. Match this to the request Id from the original request.

As2From identifies the sender of the CEM request.

When this event fires the CEMDetails property will be populated. Inspect the Accepted field to determine whether each CEM request was accepted. If the request was rejected, check RejectionReason for details.

When this event fires the following CEMDetails fields are applicable:

CertIssuer
CertSerialNumber
Accepted
RejectionReason

EDIDataInfo Event (AS2Receiver Class)

Fired when processing an incoming message.

Syntax

ANSI (Cross Platform)
virtual int FireEDIDataInfo(AS2ReceiverEDIDataInfoEventParams *e);

typedef struct {
  const char *Name;
  const char *DataType;
  int Duplicate;
  int reserved;
} AS2ReceiverEDIDataInfoEventParams;


Unicode (Windows)
virtual INT FireEDIDataInfo(AS2ReceiverEDIDataInfoEventParams *e);

typedef struct {
  LPCWSTR Name;
  LPCWSTR DataType;
  BOOL Duplicate;
  INT reserved;
} AS2ReceiverEDIDataInfoEventParams;

#define EID_AS2RECEIVER_EDIDATAINFO 3

virtual INT IPWORKSEDI_CALL FireEDIDataInfo(LPSTR &lpszName, LPSTR &lpszDataType, BOOL &bDuplicate);

class AS2ReceiverEDIDataInfoEventParams {
public:
  const QString &Name();

  const QString &DataType();

  bool Duplicate();
  void SetDuplicate(bool bDuplicate);

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

// To handle, connect one or more slots to this signal.
void EDIDataInfo(AS2ReceiverEDIDataInfoEventParams *e);

// Or, subclass AS2Receiver and override this emitter function.
virtual int FireEDIDataInfo(AS2ReceiverEDIDataInfoEventParams *e) {...}

Remarks

When ParseRequest or ProcessRequest has been called this event will fire and provide the filename of the incoming data via the Name parameter. DataType will be the EDI type specified in the message, such as "application/edi-x12".

Duplicate is used in conjunction with the InvalidFileNameMDNAction configuration setting when Filename Preservation with an Associated MDN Response is implemented in the receiving agent to support MDN responses for duplicate filenames. If IncomingDirectory is specified, the Duplicate parameter will return True if the filename specified in the request exists on disk. Additionally, the Duplicate parameter may be set to True before the event exits so that checking for duplicate filenames may be extended to the application logic.

Error Event (AS2Receiver Class)

Fired when information is available about errors during data delivery.

Syntax

ANSI (Cross Platform)
virtual int FireError(AS2ReceiverErrorEventParams *e);

typedef struct {
  int ErrorCode;
  const char *Description;
  int reserved;
} AS2ReceiverErrorEventParams;


Unicode (Windows)
virtual INT FireError(AS2ReceiverErrorEventParams *e);

typedef struct {
  INT ErrorCode;
  LPCWSTR Description;
  INT reserved;
} AS2ReceiverErrorEventParams;

#define EID_AS2RECEIVER_ERROR 4

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

class AS2ReceiverErrorEventParams {
public:

  const QString &Description();

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

// To handle, connect one or more slots to this signal.
void Error(AS2ReceiverErrorEventParams *e);

// Or, subclass AS2Receiver and override this emitter function.
virtual int FireError(AS2ReceiverErrorEventParams *e) {...}

Remarks

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

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

Log Event (AS2Receiver Class)

Fired with log information while processing a message.

Syntax

ANSI (Cross Platform)
virtual int FireLog(AS2ReceiverLogEventParams *e);

// To handle, connect one or more slots to this signal.
void Log(AS2ReceiverLogEventParams *e);

// Or, subclass AS2Receiver and override this emitter function.
virtual int FireLog(AS2ReceiverLogEventParams *e) {...}

Remarks

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

Log messages available through this event correspond to log files written to LogDirectory. This event provides a way to obtain log messages without relying on files on disk. This event fires regardless of the value of LogDirectory (i.e. when LogDirectory is empty the event will still fire).

The LogMessage event parameter holds the raw log data.

The LogType event parameter indicates the type of log. Possible values are:


"LOG"	Information about the status of the process.
"ERR"	An error was encountered.
"DAT"	The EDI payload.

void RecipientInfo(AS2ReceiverRecipientInfoEventParams *e);

// Or, subclass AS2Receiver and override this emitter function.
virtual int FireRecipientInfo(AS2ReceiverRecipientInfoEventParams *e) {...}

Remarks

When ParseRequest or ProcessRequest has been called on a valid encrypted message, this event will fire for each recipient certificate that the message has been encrypted for.

Issuer is the subject of the issuer certificate.

SerialNumber is the serial number of the encryption certificate.

SubjectKeyIdentifier is the X.509 subjectKeyIdentifier extension value of the certificate used to sign the message encoded as a hex string.

EncryptionAlgorithm is the encryption algorithm used to encrypt the message. Possible values are as follows:

"3DES"
"DES"
"RC2CBC40"
"RC2CBC64"
"RC2CBC128" or "RC2"
"AESCBC128" or "AES"
"AESCBC192"
"AESCBC256"
"AESGCM128" or "AESGCM"
"AESGCM192"
"AESGCM256"

SignerCertInfo Event (AS2Receiver Class)

This event is fired during verification of the signed message.

Syntax

ANSI (Cross Platform)
virtual int FireSignerCertInfo(AS2ReceiverSignerCertInfoEventParams *e);

typedef struct {
  const char *Issuer;
  const char *SerialNumber;
  const char *SubjectKeyIdentifier;

typedef struct {
  LPCWSTR Issuer;
  LPCWSTR SerialNumber;
  LPCWSTR SubjectKeyIdentifier;
  LPCSTR CertEncoded;
  INT lenCertEncoded;
  INT reserved;
} AS2ReceiverSignerCertInfoEventParams;

#define EID_AS2RECEIVER_SIGNERCERTINFO 7

virtual INT IPWORKSEDI_CALL FireSignerCertInfo(LPSTR &lpszIssuer, LPSTR &lpszSerialNumber, LPSTR &lpszSubjectKeyIdentifier, LPSTR &lpCertEncoded, INT &lenCertEncoded);

class AS2ReceiverSignerCertInfoEventParams {
public:
  const QString &Issuer();

  const QString &SerialNumber();

  const QString &SubjectKeyIdentifier();

  const QByteArray &CertEncoded();

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

// To handle, connect one or more slots to this signal.
void SignerCertInfo(AS2ReceiverSignerCertInfoEventParams *e);

// Or, subclass AS2Receiver and override this emitter function.
virtual int FireSignerCertInfo(AS2ReceiverSignerCertInfoEventParams *e) {...}

Remarks

During verification, this event will be raised while parsing the signer's certificate information. The parameters that are populated depend on the options used when the message was originally signed. This information may be used to select the correct certificate for SignerCert to verify the signature. The following parameters may be populated:

Issuer specifies the subject of the issuer of the certificate used to sign the message.

SerialNumber is the serial number of the certificate used to sign the message.

SubjectKeyIdentifier is the X.509 subjectKeyIdentifier extension value of the certificate used to sign the message encoded as a hex string.

CertEncoded is the PEM (Base64 encoded) public certificate needed to verify the signature.

Note: When this value is present, the class will automatically use this value to perform signature verification.

The SignerCert property may be set from within this event. In this manner, the decision of which signer certificate to load may be delayed until the parameters of this event are inspected and the correct certificate can be located and loaded.

SSLServerAuthentication Event (AS2Receiver Class)

For asynchronous HTTPS MDNs, fired after the server presents its certificate.

Syntax

ANSI (Cross Platform)
virtual int FireSSLServerAuthentication(AS2ReceiverSSLServerAuthenticationEventParams *e);

typedef struct {
  const char *CertEncoded;
  int lenCertEncoded;
  const char *CertSubject;
  const char *CertIssuer;
  const char *Status;
  int Accept;
  int reserved;
} AS2ReceiverSSLServerAuthenticationEventParams;


Unicode (Windows)
virtual INT FireSSLServerAuthentication(AS2ReceiverSSLServerAuthenticationEventParams *e);

typedef struct {
  LPCSTR CertEncoded;
  INT lenCertEncoded;
  LPCWSTR CertSubject;
  LPCWSTR CertIssuer;

  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(AS2ReceiverSSLServerAuthenticationEventParams *e);

// Or, subclass AS2Receiver and override this emitter function.
virtual int FireSSLServerAuthentication(AS2ReceiverSSLServerAuthenticationEventParams *e) {...}

Remarks

This event is fired when returning asynchronous MDNs over HTTPS to the client, and allows the client can decide whether to continue with the connection process or not. In general, the class will allow self-signed certs only if explicitly specified.

To accept a self-signed certificate, either trap the SSLServerAuthentication event and set Accept to true based on the values of CertSubject, CertEncoded, etc., or set the SSLAcceptServerCert property to the value of the expected certificate (if the server certificate is known in advance the latter method is simpler).

SSLStatus Event (AS2Receiver Class)

Fired when secure connection progress messages are available.

Syntax

ANSI (Cross Platform)
virtual int FireSSLStatus(AS2ReceiverSSLStatusEventParams *e);

typedef struct {
  const char *Message;

IPWorksEDIList Type

Syntax

IPWorksEDIList<T> (declared in ipworksedi.h)

Remarks

IPWorksEDIList is a generic class that is used to hold a collection of objects of type T, where T is one of the custom types supported by the AS2Receiver class.

Methods

GetCount	This method returns the current size of the collection. int GetCount() {}
SetCount	This method sets the size of the collection. This method returns `0` if setting the size was successful; or `-1` if the collection is `ReadOnly`. When adding additional objects to a collection call this method to specify the new size. Increasing the size of the collection preserves existing objects in the collection. int SetCount(int count) {}
Get	This method gets the item at the specified position. The `index` parameter specifies the index of the item in the collection. This method returns `NULL` if an invalid `index` is specified. T* Get(int index) {}
Set	This method sets the item at the specified position. The `index` parameter specifies the index of the item in the collection that is being set. This method returns `-1` if an invalid `index` is specified. Note: Objects created using the `new` operator must be freed using the `delete` operator; they will not be automatically freed by the class. T* Set(int index, T* value) {}

Config Settings (AS2Receiver 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.

AS2Receiver Config Settings

AcceptAnySignerCert: Used to accept trust any signing certificate unconditionally.

If AcceptAnySignerCert is set to true, the class will accept any signer certificate for the incoming signature. Use of this setting in production is discouraged, as failing to authenticate the sender poses a security risk.

AS2VersionIncoming: The version of AS2 that was used in the incoming message.

The version of AS2 that was used in the incoming message.

AS2VersionOutgoing: The version of AS2 to be used in the outgoing message.

The version of AS2 to be used in the outgoing message.

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

If the Authorization setting contains a non-empty string, an Authorization HTTP request header is added to the request. This header conveys Authorization information to the server.

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

The AuthScheme; setting 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 setting in the form "Basic [encoded-user-password]".

AuthScheme: The authorization scheme to be used when server authorization is to be performed.

Use the AuthScheme property to tell the component which type of authorization to perform when the User and Password properties are set. Possible values are:


0 (default)	Basic
1	Digest
2	Proprietary
3	None
4	NTLM
5	Negotiate
6	OAuth

By default, AuthScheme is Basic (0), and if the User and Password configuration settings are set, the component will attempt basic authentication. If AuthScheme is set to Digest (1), digest authentication will be attempted instead.

For security reasons, setting this value will clear the values of User and Password.

CEMCertDir: Specifies the directory where certificates are saved when receiving a CEM request.

This setting specifies a relative or absolute path on disk where certificates received from a CEM request will be saved. The filename format is: CEMRequestId + "_" + CertId + ".cer" The CEMRequestId may be retrieved from the CEMRequest event. Any invalid characters will be replaced with "_". If there is an error writing the file to disk the Error event will fire with details. To overwrite existing certificate files set OverwriteCEMCerts to True.

If this is not set, the certificates will be held in memory and can be accessed via CEMDetails. See CEMRequest for details.

CloseStreamAfterProcessing: Specifies whether or not the OutputStream should be closed after processing.

Determines if the stream specified by OutputStream is closed after ParseRequest or ProcessRequest returns. By default this is True. Setting this to False keeps the stream open for further use.

DecodeTempDirectory: The temp directory the class will use to decode messages.

This configuration is only necessary when decoding EDI messages that contain attachments. If a value is specified for DecodeTempDirectory, the class will first decode the S/MIME message to the temp directory, then decode the embedded MIME message containing attachments to the IncomingDirectory.

Note: When using this configuration, if IncomingDirectory is not set, the class will not clean up any temp files it creates. These files must be monitored and cleaned manually by the user.

DetectDuplicates: Whether to detect duplicate messages.

When receiving messages this setting controls whether the class attempts to detect duplicate messages. Consider the following scenario:

A sender transmits a message, it is successfully received but the MDN cannot be delivered due to a network error. The sender does not receive the MDN and retransmits the message.

This results in two messages being received and processed. In most cases this is not an issue as the backend processing done outside of the class will detect duplicate messages. However, this setting may be enabled to have the class check for duplicates to prevent duplicate incoming messages.

When enabled, LogDirectory must be set to a value that will resolve to the same location for both received requests. This means the "%Date:Format%" macro must not be used in the LogDirectory value. Additionally, this functionality can only work if the sender uses the same MessageId in both requests.

If a duplicate is detected, no exception is thrown, but the class will respond with an MDN including a warning that a duplicate was detected. The message in the duplicate request will not be processed.

The default value is False.

EncryptionAlgorithm: The encryption algorithm used to encrypt the incoming data.

If the data is encrypted, EncryptionAlgorithm will contain the encryption algorithm used to encrypt the data; i.e., "3DES". If the data is not encrypted EncryptionAlgorithm will contain an empty string.

EncryptionPaddingScheme: The encryption padding scheme used when encrypting the incoming data.

If the data is encrypted this setting contains the padding scheme used when the data was originally encrypted. Possible values are:

RSAES-PKCS1-v1_5
RSAES-OAEP

EncryptionType: The MIME type of the encrypted data.

If the data is encrypted, EncryptionType will contain the MIME type of the encrypted data; i.e., "application/pkcs7-mime". If the data is not encrypted EncryptionType will contain an empty string.

At present only "application/pkcs7-mime" is supported for decryption.

ErrorProcessingFlags: Flags controlling how errors affect ProcessRequest.

By default, ParseRequest will halt and throw an exception if Request contains errors or requests algorithms, protocols, or receipt types not supported by the class. By setting ErrorProcessingFlags the class can be configured to not halt for certain types of errors. The errors will still be reported in ScanResult.

Use of this property allows EDIData to be determined even if the class is not fully able to respond to the client's request.

ErrorReportingFlags control how the errors are reported in the MDNReceipt.

The value should be set to the OR of one or more of the following values:

0x04 Unable to validate integrity of data, or unsupported signing protocol used.

0x08 Unable to authenticate the sender.

0x10 Client requested unsupported signature type.

0x20 Client requested unsupported MIC algorithm.

ErrorReportingFlags: Flags controlling how errors affect the MDNReceipt.

By default, MDNReceipt will report an error if any of the conditions below occur. The MIC will not be calculated and the data will be reported as unprocessed.

The MDNReceipt may be configured to permit one or more of the errors below. A warning will be reported if MDNWarning is set; otherwise the error will silently be ignored. Note that errors should be ignored only with extreme caution, and only by agreement of both trading parties.

Multiple errors may be permitted by OR-ing the flags together.

The value should be set to the OR of one or more of the following values:

0x04 Unable to validate integrity of data, or unsupported signing protocol used.

0x08 Unable to authenticate the sender.

0x10 Client requested unsupported signature type.

0x20 Client requested unsupported MIC algorithm.

FileNameSource: The location from which to read the filename.

This setting specifies whether to read the filename from the MIME part header (default) or the HTTP header.

When processing a request that supports filename preservation the filename will be read from the MIME body part by default. The MIME body part should hold the filename in the Content-Disposition header for that part as per the specification.

Some implementations do not behave according to the specification and specify the filename in the HTTP Content-Disposition header instead of the MIME part headers.

Possible value are:


0 (default)	MIME part header
1	HTTP header
2	Content-Type MIME part header

IgnoreLoggingErrors: Whether to ignore errors that occur when writing to the log.

When this setting is enabled (default False), any errors that occur while writing to log files will be ignored, and no exception will be thrown. Note that this may cause logs to be incomplete or missing without any indication that an issue occurred.

InvalidFileNameMDNAction: Instructs MDN disposition on invalid and duplicate filenames.

Used to implement support for Filename Preservation with Associated MDN Response as requested by the Financial Services Technical Consortium (fstc.org). The following options are supported:


0	Continue
1	Warn
2	Fail

By default, the class will return a positive MDN receipt regardless of what value was provided as a filename in the transmission, renaming the filename to a valid value if a file with the filename value provided could not be written to the location specified in IncomingDirectory.

If set to 1 (Warn), the class will rename the filename as above to avoid file conflicts, but will issue a MDN warning when the filename provided is missing, contains invalid characters, or is detected as a duplicate (this behavior is governed by the Duplicate parameter of the EDIDataInfo event).

If set to 2 (Fail), the class will reject transmissions where the filename provided is missing, contains invalid characters, or is detected as a duplicate.

LogDebug: Whether to log debug data.

This setting specifies whether to log debug data. When set to True the class will create additional files in the LogDirectory. The default value is False.

When sending, files with extensions ".input", ".sign", ".compress", and ".encrypt" may be created. When receiving, files with extensions ".input", ".verify", ".decompress", and ".decrypt" may be created.

LogFilename: The base name of the log file.

If set, this will be used as for the filename of the log file.

Note that only the base name should be specified as the component will append the appropriate file extension.

LogOptions: The information to be written to log files.

When LogDirectory is set, several pieces of information are written to log files in the specified directory. Set LogOptions to one or more of the following values to control what information is written to file. When specifying multiple values, include them in the same string (i.e. "LogOptions=Status, Response, Payload"):


Status	Contains information on applied security options and pass/fail status of transmission
Request	Contains the raw incoming request before processing
Payload	Contains log of processed payload after transmission
MDN	Contains the MDN receipt response to a request
Errors	This is only written in an error is encountered, containing the error.
All	All of the above

MaxParts: The maximum number of MIME parts to process.

Messages may contain multiple MIME parts if attachments are present. This setting specifies the maximum number of MIME parts to process. The default value is "100", which means 99 attachments will be processed. Each message contains one MIME part for the body, and one additional MIME part for each attachment. Set this value to "-1" to indicate no restrictions.

MDNDisposition: Overrides the automatically calculated MDN disposition.

If specified, this setting overrides the MDN disposition that was automatically calculated by the class. In most cases this is not necessary but may be used when specifying a custom Disposition header is required. For instance: as2receiver.Config("MDNDisposition=message-deemed-invalid-due-to-unknown-from-and.or-to-parties");

MDNMICAlgorithm: The algorithm used to sign the outgoing MDN.

By default, the component will honor the request of the client, if possible. The MIC will be calculated using the requested algorithm, stored in the MICValue property of MDNReceipt, and reported in the outgoing MDN. If not possible, the MDN will not be signed, and ParseRequest will throw an exception unless ErrorProcessingFlags has been configured to prevent this. The following options are supported:


0	As Requested
1	As Requested Or SHA1
2	SHA1
3	MD5
4	None
5	SHA-256
6	SHA-384
7	SHA-512
8	SHA-224
9	As Requested Or SHA-256

This setting may be configured in a variety of other ways, as well. If set to As Requested Or SHA-256 (9), the component will honor requests for a signed receipt as with As Requested (0). If unable to comply, or if a signature was not explicitly requested, the MIC will still be calculated using the SHA-256 algorithm. The ReceiptSigningProtocol property may then be set to return a signed receipt.

The property may be set to one of the listed values above to override the client's request, and use the specified signing algorithm. Use extreme caution when doing this; it will result in a non-RFC compliant server.

MDNReportingUA: The name of the user agent performing the disposition.

The name of the user agent performing the disposition. The RFC 2298 recommendation is to use the DNS name of the user agent and the name of the software performing the disposition, for example, "edi-server.nsoftware.com; /n software EDI Server Demo".

MDNSendingMode: The level of end user interaction involved in sending the MDN.

MDNSendingMode allows the server software to describe the level of user interaction in sending the MDN. MDNSendingMode corresponds to the "disposition-mode" field in the Disposition Header, as described further in RFC 3335. The following values are supported:


0	Automatic
1	User Configurable
2	Manual

By default, the disposition-mode value will be "automatic-action/MDN-sent-automatically".

MDNWarning: A warning to appear in the MDN.

MDNWarning defines a warning to appear in the outgoing MDNReceipt. If any errors are returned in ScanResult and not marked as to be allowed in ErrorReportingFlags the errors will take precedence and the warning will not be reported.

MDNWarning should be assigned when allowing the errors returned in ScanResult. The MDNReceipt will indicate successful processing of Request, but will contain a Warning field. The following warnings are defined by the AS2 specifications:

"authentication-failed, processing continued"

Any other warnings are not defined by the specifications and may or may not be understood by the client.

NormalizeMIC: Whether to normalize line endings before calculating the MIC.

This setting determines whether to normalize line endings before signature verification.

In most cases the signature is verified by calculating a Message Integrity Check (MIC) over the exact data that is received. In some cases other software such as Mendelson AS2 may calculate signatures over a version of the data with normalized line endings. During processing attempts to verify a signature that was created in this manner may lead to one of the following errors:

Unable to verify content integrity: Message digest mismatch in signature.
The receipt signature could not be verified: Message digest mismatch in signature.

If one of the errors above is encountered and the received data is expected to be otherwise correct setting this setting to True may resolve the issue by normalizing line endings before verifying the signature.

Note: This should only be set to True if there is a specific reason to do so.

OverwriteCEMCerts: Whether existing CEM certificates are overwritten when a duplicate is received.

This setting specifies whether CEM certificates are overwritten in CEMCertDir when another certificate with the same name and Id is received. The default value is False.

Password: A password if authentication is to be used.

If AuthScheme is set to Basic, the User and Password are Base64 encoded and the result is put in the Authorization configuration setting in the form "Basic [encoded-user-password]".

If AuthScheme is set to Digest, the User and Password properties are used to respond to the HTTP Digest Authentication challenge from the server.

The User and Password properties must be set only after the URL property is set. When the URL property is set, for security reasons, User and Password are immediately cleared.

ProcessingError: A processing error occurred in the received EDI message.

If ProcessingError is set to "True" before invoking CreateMDNReceipt, a MDN with the disposition "processed/Error: unexpected-processing-error" is returned.

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

This setting is used while sending an asynchronous MDN.

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

This setting is used while sending an asynchronous MDN.

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

This setting is used while sending an asynchronous MDN.

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

This setting is used while sending an asynchronous MDN.

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

This setting is used while sending an asynchronous MDN.

ReceiptSigningProtocol: The protocol used to sign the outgoing MDN receipt.

The protocol used to sign the outgoing MDNReceipt. The following values are supported:


0	As Requested
1	PKCS7
2	None

By default, the component will honor the request of the client, if possible. If not possible, the MDNReceipt will not be signed, and ParseRequest will throw an exception unless ErrorProcessingFlags has been configured to prevent this.

If the client does not request a signature, one will not be provided by default. However, the server may provide one by setting ReceiptSigningProtocol to PKCS7 (1). If the client requests a signature, and the signature protocol is supported by the component, the request must be honored, per RFC specifications.

RequestedMICAlgorithms: The Message Integrity Check algorithm(s) requested by the client, if any.

This property will contain the algorithm(s) requested ("sha1", "md5", "sha-256", etc.) as well as the importance ("required" or "optional") specified by the client. If multiple algorithms are specified, precedence is given to the ones on the left. Formatting is as in RFC 3335, e.g., "optional, sha1, md5".

This setting will contain an empty string if a MIC was not requested.

RequestedSignatureProtocol: The signing protocol requested by the client, if any.

This property will contain the protocol requested ("pkcs7-signature" or "pgp-signature") as well as the importance ("required" or "optional") specified by the client, as formatted in RFC 3335, e.g., "optional, pkcs7-signature".

This setting will contain an empty string if a signature was not requested.

RequestFile: Reads the AS2 message from disk.

This config allows for the AS2 message to be read from a file at the specified location on disk. The file can contain either just the body of the AS2 request, or it can contain both the headers and the body.

If the file includes the headers, they should be separated from the body by a double CRLF pair. If the file doesn't include the headers, they will need to be set to the RequestHeadersString property.

RequireAS2To: Ensure that the received message is intended for the given AS2 identifier.

This setting is used while processing the received message and causes an exception to be thrown if the message is not intended for the receiver specified by RequireAS2To.

RequiredSignatureAlgorithms: Specifies a list of acceptable signature algorithms.

This setting specifies a comma separated list of allowed signature algorithms used in messages verified by the class. By default the setting is empty and any signature algorithm is supported. To restrict the algorithms to one or more values set this setting to a comma separated list. For instance sha1,sha256.

RequireEncrypt: Ensure that the received message is encrypted.

This setting is used while processing the received message and causes an exception to be thrown if the encryption requirement is not met.

RequireOAEP: Ensure that the encryption padding mode is RSAES-OAEP.

This setting is used while processing the received message and enforces a requirement that the EncryptionPaddingScheme be RSAES-OAEP. If the message was encrypted with any other padding scheme the class fails with an error

RequirePSS: Ensure that the signature scheme in the received message is RSASSA-PSS.

This setting is used while processing the received message and enforces a requirement that the SenderSignatureScheme be RSASSA-PSS. If the message was signed with any other scheme the class fails with an error

RequireSign: Ensure that the received message is signed.

This setting is used while processing the received message and causes an exception to be thrown if the signature requirement is not met.

ResponseSubject: The subject to be used for the MDN response.

The human-readable subject to be used for the MDN response.

SenderSignatureAlgorithm: The algorithm used by the sender to sign the message.

This will contain the name of the algorithm used to sign the incoming message. Possible values are:

sha1
md5
sha-256
sha-384
sha-512
sha-224

SenderSignatureScheme: The signature scheme used by the sender to sign the message.

This setting returns the signature scheme used when the incoming message was originally signed. Possible values are:

RSASSA-PKCS1-v1_5
RSASSA-PSS

SignatureType: The MIME type of the signature (if any).

This setting will contain an empty string if a signature was not requested.

SignerCACert: CA certificate used to verify signed messages.

This setting specifies one or more CA certificates to be used when verifying signed messages.

To support multiple CA signing certificates, add all the certificates in the chain by prepending a '+' character to the PEM formatted certificate data. For example, the code below adds two certs to the RootCertificate property. as2receiver.RootCertificate = cert1; as2receiver.RootCertificate = "+" + cert2;

SMTPFrom: The email address of the sender of the message.

In case an asynchronous MDN is requested over SMTP, the sender; i.e., the value of "From".

SMTPServer: The SMTP server to be used.

In case an asynchronous MDN is delivered over SMTP, the address of the server to be used to send it.

User: A user name if authentication is to be used.

If AuthScheme is set to Basic, the User and Password are Base64 encoded and the result is put in the Authorization configuration setting in the form "Basic [encoded-user-password]".

If AuthScheme is set to Digest, the User and Password properties are used to respond to the HTTP Digest Authentication challenge from the server.

The User and Password properties must be set only after the URL property is set. When the URL property is set, for security reasons, User and Password are immediately cleared.

WarnOnMDNFailure: Whether to log a .wrn file instead of a .err file when MDN delivery fails.

This setting controls whether to log a .wrn file or a .err file in the LogDirectory when MDN delivery fails. When set to True and MDN delivery fails a .wrn file is created in the LogDirectory. This allows an application to treat MDN failures as warnings when monitoring log files. When set to False and MDN delivery fails a .err file is created. The default value is False.

Note: This setting is not applicable when calling SendAsyncMDN.

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 User and Password are specified, this value is calculated using the algorithm specified by AuthScheme.

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 AutoDetect 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.

Possible values are as follows:


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

Note: This setting is provided for use by 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 multihomed 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 multihomed hosts (machines with more than one IP interface).

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

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

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

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

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

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

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

MaxTransferRate: The transfer rate limit in bytes per second.

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

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

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

www.google.com;www.nsoftware.com

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

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

Note: This value is not applicable in Java.

TcpNoDelay: Whether or not to delay when sending packets.

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

By default, this configuration setting is set to False.

UseIPv6: Whether to use IPv6.

When set to 0 (default), the 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 as follows:


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

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

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

OpenSSLCADir: The path to a directory containing CA certificates.

This functionality is available only when the provider is OpenSSL.

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

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

This functionality is available only when the provider is OpenSSL.

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

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

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

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

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

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

This functionality is available only when the provider is OpenSSL.

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

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

This functionality is available only when the provider is OpenSSL.

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

ReuseSSLSession: Determines if the SSL session is reused.

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

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

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

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

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

The default value is as follows:

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

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

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

-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw
... Intermediate Cert ...
eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w

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

SSLCipherStrength: The minimum cipher strength used for bulk encryption.

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

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

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

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

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

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

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

-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw
... Intermediate Cert ...
eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w

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

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

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

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

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

Multiple cipher suites are separated by semicolons.

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

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

TLS_AES_256_GCM_SHA384
TLS_CHACHA20_POLY1305_SHA256
TLS_AES_128_GCM_SHA256

SSLEnabledCipherSuites is used together with SSLCipherStrength.

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

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

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


TLS1.3	12288 (Hex 3000)
TLS1.2	3072 (Hex C00) (Default - Client and Server)
TLS1.1	768 (Hex 300) (Default - Client)
TLS1	192 (Hex C0) (Default - Client)
SSL3	48 (Hex 30)
SSL2	12 (Hex 0C)

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

SSLEnabledProtocols: Transport Layer Security (TLS) 1.3 Notes:

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

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

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

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

SSLEnabledProtocols: SSL2 and SSL3 Notes:

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

SSLEnableRenegotiation: Whether the renegotiation_info SSL extension is supported.

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

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

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

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

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

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

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

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

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

SSLNegotiatedCipher: Returns the negotiated cipher suite.

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

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

SSLNegotiatedCipherStrength: Returns the negotiated cipher suite strength.

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

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

SSLNegotiatedCipherSuite: Returns the negotiated cipher suite.

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

SSLNegotiatedKeyExchange: Returns the negotiated key exchange algorithm.

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

SSLNegotiatedKeyExchangeStrength: Returns the negotiated key exchange algorithm strength.

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

SSLNegotiatedVersion: Returns the negotiated protocol version.

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

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

SSLSecurityFlags: Flags that control certificate verification.

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


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

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

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

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

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

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

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

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

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

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

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

TLS12SupportedGroups: The supported groups for ECC.

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

The default value is ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1.

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

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

TLS13KeyShareGroups: The groups for which to pregenerate key shares.

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

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

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

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

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

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

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

TLS13SignatureAlgorithms: The allowed certificate signature algorithms.

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

"ed25519" (default)
"ed448" (default)
"ecdsa_secp256r1_sha256" (default)
"ecdsa_secp384r1_sha384" (default)
"ecdsa_secp521r1_sha512" (default)
"rsa_pkcs1_sha256" (default)
"rsa_pkcs1_sha384" (default)
"rsa_pkcs1_sha512" (default)
"rsa_pss_sha256" (default)
"rsa_pss_sha384" (default)
"rsa_pss_sha512" (default)

The default value is rsa_pss_sha256,rsa_pss_sha384,rsa_pss_sha512,rsa_pkcs1_sha256,rsa_pkcs1_sha384,rsa_pkcs1_sha512,ecdsa_secp256r1_sha256,ecdsa_secp384r1_sha384,ecdsa_secp521r1_sha512,ed25519,ed448. This configuration setting is applicable only when SSLEnabledProtocols includes TLS 1.3.

TLS13SupportedGroups: The supported groups for (EC)DHE key exchange.

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

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

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

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

Socket Config Settings

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

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

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

FirewallData: Used to send extra data to the firewall.

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

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

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

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the 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. In some cases, increasing the value of the OutBufferSize setting can provide significant improvements in performance.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the 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.

MaskSensitiveData: Whether sensitive data is masked in log messages.

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

This setting only works on these 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.

UseFIPSCompliantAPI: Tells the class whether or not to use FIPS certified APIs.

When set to true, the class will utilize the underlying operating system's certified APIs. Java editions, regardless of OS, utilize Bouncy Castle Federal Information Processing Standards (FIPS), while all other Windows editions make use of Microsoft security libraries.

FIPS mode can be enabled by setting the UseFIPSCompliantAPI configuration setting to true. This is a static setting that applies to all instances of all classes of the toolkit within the process. It is recommended to enable or disable this setting once before the component has been used to establish a connection. Enabling FIPS while an instance of the component is active and connected may result in unexpected behavior.

For more details, please see the FIPS 140-2 Compliance article.

Note: This setting is applicable only on Windows.

Note: Enabling FIPS compliance requires a special license; please contact sales@nsoftware.com for details.

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.

Trappable Errors (AS2Receiver 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.
