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 EDIEDIType and EDIData.

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);

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.

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.

To use a security key, the necessary data must first be collected using the CertMgr class. The ListStoreCertificates method may be called after setting CertStoreType to cstPKCS11, CertStorePassword to the PIN, and CertStore to the full path of the PKCS#11 DLL. The certificate information returned in the CertList event's CertEncoded parameter may be saved for later use.

When using a certificate, pass the previously saved security key information as the RolloverCertStore and set RolloverCertStorePassword to the PIN.

Code Example. SSH Authentication with Security Key: certmgr.CertStoreType = CertStoreTypes.cstPKCS11; certmgr.OnCertList += (s, e) => { secKeyBlob = e.CertEncoded; }; certmgr.CertStore = @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll"; certmgr.CertStorePassword = "123456"; //PIN certmgr.ListStoreCertificates(); sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11, secKeyBlob, "123456", "*"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22);

Object Oriented Interface


public function getSignerCertStoreType();


public function setSignerCertStoreType($value);

Procedural Interface


ipworksedi_as2receiver_get($res, 132 );


ipworksedi_as2receiver_set($res, 132, $value );

Default Value

0

Remarks

This is the type of certificate store for this certificate.

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

0 (cstUser - default)For Windows, this specifies that the certificate store is a certificate store owned by the current user.

Note: This store type is not available in Java.

1 (cstMachine)For Windows, this specifies that the certificate store is a machine store.

Note: This store type is not available in Java.

2 (cstPFXFile)The certificate store is the name of a PFX (PKCS#12) file containing certificates.
3 (cstPFXBlob)The certificate store is a string (binary or Base64-encoded) representing a certificate store in PFX (PKCS#12) format.
4 (cstJKSFile)The certificate store is the name of a Java Key Store (JKS) file containing certificates.

Note: This store type is only available in Java.

Note: This store type is only available in Java and .NET.

23 (cstPKCS11)The certificate is present on a physical security key accessible via a PKCS#11 interface.

To use a security key, the necessary data must first be collected using the CertMgr class. The ListStoreCertificates method may be called after setting CertStoreType to cstPKCS11, CertStorePassword to the PIN, and CertStore to the full path of the PKCS#11 DLL. The certificate information returned in the CertList event's CertEncoded parameter may be saved for later use.

When using a certificate, pass the previously saved security key information as the SignerCertStore and set SignerCertStorePassword to the PIN.

Code Example. SSH Authentication with Security Key: certmgr.CertStoreType = CertStoreTypes.cstPKCS11; certmgr.OnCertList += (s, e) => { secKeyBlob = e.CertEncoded; }; certmgr.CertStore = @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll"; certmgr.CertStorePassword = "123456"; //PIN certmgr.ListStoreCertificates(); sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11, secKeyBlob, "123456", "*"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22);

AckRequest Method (IPWorksEDI_AS2Receiver Class)

Optional. Acknowledges the incoming request.

Object Oriented Interface

public function doAckRequest();

Procedural Interface

ipworksedi_as2receiver_do_ackrequest($res);

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.

Config Method (IPWorksEDI_AS2Receiver Class)

Sets or retrieves a configuration setting.

Object Oriented Interface

public function doConfig($configurationstring);

Procedural Interface

ipworksedi_as2receiver_do_config($res, $configurationstring);

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.

CreateMDNReceipt Method (IPWorksEDI_AS2Receiver Class)

Creates MDNReceipt .

Object Oriented Interface

public function doCreateMDNReceipt($headers, $mdn, $message);

Procedural Interface

ipworksedi_as2receiver_do_createmdnreceipt($res, $headers, $mdn, $message);

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.

ParseRequest Method (IPWorksEDI_AS2Receiver Class)

Parses the EDI message and determines the EDIData .

Object Oriented Interface

public function doParseRequest();

Procedural Interface

ipworksedi_as2receiver_do_parserequest($res);

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.

ProcessRequest Method (IPWorksEDI_AS2Receiver Class)

Processes the EDI data, and generates the receipt.

Object Oriented Interface

public function doProcessRequest();

Procedural Interface

ipworksedi_as2receiver_do_processrequest($res);

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.

ProcessRestartRequest Method (IPWorksEDI_AS2Receiver Class)

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

Object Oriented Interface

public function doProcessRestartRequest();

Procedural Interface

ipworksedi_as2receiver_do_processrestartrequest($res);

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.

ReadRequest Method (IPWorksEDI_AS2Receiver Class)

Reads the AS2 request from the HTTP session.

Object Oriented Interface

public function doReadRequest();

Procedural Interface

ipworksedi_as2receiver_do_readrequest($res);

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:

ParseRequest may be used to scan the entire message.

Reset Method (IPWorksEDI_AS2Receiver Class)

Resets the state of the control.

Object Oriented Interface

public function doReset();

Procedural Interface

ipworksedi_as2receiver_do_reset($res);

Remarks

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

SendAsyncMDN Method (IPWorksEDI_AS2Receiver Class)

Sends the MDNReceipt to the RemoteURL specified.

Object Oriented Interface

public function doSendAsyncMDN($remoteurl, $mdnreceipt, $mdnreceiptheaders);

Procedural Interface

ipworksedi_as2receiver_do_sendasyncmdn($res, $remoteurl, $mdnreceipt, $mdnreceiptheaders);

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.

SendResponse Method (IPWorksEDI_AS2Receiver Class)

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

Object Oriented Interface

public function doSendResponse();

Procedural Interface

ipworksedi_as2receiver_do_sendresponse($res);

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. In ASP.NET, the receipt will be sent within the current HTTP context. In Java, the receipt will be sent within the provided HttpServletResponse. 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.

SetTPInfo Method (IPWorksEDI_AS2Receiver Class)

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

Object Oriented Interface

public function doSetTPInfo($profile);

Procedural Interface

ipworksedi_as2receiver_do_settpinfo($res, $profile);

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();

CEMRequest Event (IPWorksEDI_AS2Receiver Class)

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

Object Oriented Interface

public function fireCEMRequest($param);

Procedural Interface

ipworksedi_as2receiver_register_callback($res, 1, array($this, 'fireCEMRequest'));

Parameter List

 'requestid'
'as2from'

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 CEMRespondByDate and CEMResponseURL. CEMRespondByDate specifies the date by which the sender expects a response. CEMResponseURL specifies the URL to which the CEM response should be sent.

When this event fires the following CEMDetails properties are applicable:

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

CEMResponse Event (IPWorksEDI_AS2Receiver Class)

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

Object Oriented Interface

public function fireCEMResponse($param);

Procedural Interface

ipworksedi_as2receiver_register_callback($res, 2, array($this, 'fireCEMResponse'));

Parameter List

 'requestid'
'as2from'

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 CEMAccepted property to determine whether each CEM request was accepted. If the request was rejected, check CEMRejectionReason for details.

'duplicate'

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 (IPWorksEDI_AS2Receiver Class)

Fired when information is available about errors during data delivery.

Object Oriented Interface

public function fireError($param);

Procedural Interface

ipworksedi_as2receiver_register_callback($res, 4, array($this, 'fireError'));

Parameter List

 'errorcode'
'description'

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 (IPWorksEDI_AS2Receiver Class)

Procedural Interface

ipworksedi_as2receiver_register_callback($res, 5, array($this, 'fireLog'));

Parameter List

 'logtype'
'logmessage'

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:

Object Oriented Interface

public function fireRecipientInfo($param);

Procedural Interface

ipworksedi_as2receiver_register_callback($res, 6, array($this, 'fireRecipientInfo'));

Parameter List

 'issuer'
'serialnumber'
'subjectkeyidentifier'
'encryptionalgorithm'

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 (IPWorksEDI_AS2Receiver Class)

This event is fired during verification of the signed message.

Object Oriented Interface

public function fireSignerCertInfo($param);

Procedural Interface

ipworksedi_as2receiver_register_callback($res, 7, array($this, 'fireSignerCertInfo'));

Parameter List

 'issuer'
'serialnumber'
'subjectkeyidentifier'
'certencoded'

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 (IPWorksEDI_AS2Receiver Class)

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

Object Oriented Interface

public function fireSSLServerAuthentication($param);

Procedural Interface

ipworksedi_as2receiver_register_callback($res, 8, array($this, 'fireSSLServerAuthentication'));

Parameter List

 'certencoded'
'certsubject'
'certissuer'
'status'
'accept'

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 (IPWorksEDI_AS2Receiver Class)

Fired when secure connection progress messages are available.

Object Oriented Interface

public function fireSSLStatus($param);

Procedural Interface

ipworksedi_as2receiver_register_callback($res, 9, array($this, 'fireSSLStatus'));

Parameter List

 'message'

Remarks

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

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
1Digest
2Proprietary
3None
4NTLM
5Negotiate
6OAuth
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 + "_" + CEMCertId + ".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 EDIDataOutputStream 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:

0Continue
1Warn
2Fail
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"):

StatusContains information on applied security options and pass/fail status of transmission
RequestContains the raw incoming request before processing
PayloadContains log of processed payload after transmission
MDNContains the MDN receipt response to a request
ErrorsThis is only written in an error is encountered, containing the error.
AllAll 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:

0As Requested
1As Requested Or SHA1
2SHA1
3MD5
4None
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:

0Automatic
1User Configurable
2Manual

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:

0As Requested
1PKCS7
2None
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 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.

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 ProxyUser and ProxyPassword are specified, this value is calculated using the algorithm specified by ProxyAuthScheme.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

TransferredRequest:   The full request as sent by the client.

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

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

UseChunkedEncoding:   Enables or Disables HTTP chunked encoding for transfers.

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

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

UseIDNs:   Whether to encode hostnames to internationalized domain names.

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

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

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

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

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

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

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

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

UserAgent:   Information about the user agent (browser).

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

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

TCPClient Config Settings

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

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

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

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

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

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

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

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

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

If FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the given firewall. If the authentication fails, the class fails with an error.

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

FirewallPort:   The TCP port for the FirewallHost;.

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

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

FirewallType:   Determines the type of firewall to connect through.

The appropriate values are as follows:

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

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

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

If the FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the Firewall. If the authentication fails, the class fails with an error.

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

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

When set, TCPKeepAlive will automatically be set to True. A TCP keep-alive packet will be sent after a period of inactivity as defined by KeepAliveTime. If no acknowledgment is received from the remote host, the keep-alive packet will be sent again. This configuration setting specifies the interval at which the successive keep-alive packets are sent in milliseconds. This system default if this value is not specified here is 1 second.

Note: This value is not applicable in macOS.

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

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

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

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

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

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

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

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

LingerTime:   Time in seconds to have the connection linger.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

MaxTransferRate:   The transfer rate limit in bytes per second.

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

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

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

www.google.com;www.nsoftware.com

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

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

Note: This value is not applicable in Java.

TcpNoDelay:   Whether or not to delay when sending packets.

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

By default, this config is set to false.

UseIPv6:   Whether to use IPv6.

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

0 IPv4 Only
1 IPv6 Only
2 IPv6 with IPv4 fallback

SSL Config Settings

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

When SSLProvider is set to Internal, this setting controls whether SSL packets should be logged. By default, this setting is False, as it is only useful for debugging purposes.

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

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

OpenSSLCADir:   The path to a directory containing CA certificates.

This functionality is available only when the provider is OpenSSL.

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

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

This functionality is available only when the provider is OpenSSL.

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

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

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

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

sequences. Before, between, and after the certificates text is allowed which can be used e.g. for descriptions of the certificates. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.

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

This functionality is available only when the provider is OpenSSL.

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

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

This functionality is available only when the provider is OpenSSL.

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

ReuseSSLSession:   Determines if the SSL session is reused.

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

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

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

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

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

The default value is:

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

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

This setting specifies one or more CA certificates to be included in the request when performing SSL client authentication. Some servers require the entire chain, including CA certificates, to be presented when performing SSL client authentication. The value of this setting is a newline (CrLf) separated list of certificates. For instance:

-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw
...
eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w
F0I1XhM+pKj7FjDr+XNj
-----END CERTIFICATE-----
\r \n
-----BEGIN CERTIFICATE-----
MIIEFjCCAv6gAwIBAgIQetu1SMxpnENAnnOz1P+PtTANBgkqhkiG9w0BAQUFADBp
..
d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA
-----END CERTIFICATE-----

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

This setting specifies whether the class will check the Certificate Revocation List specified by the server certificate. If set to 1 or 2, the class will first obtain the list of CRL URLs from the server certificate's CRL distribution points extension. The class will then make HTTP requests to each CRL endpoint to check the validity of the server's certificate. If the certificate has been revoked or any other issues are found during validation the class fails with an error.

When set to 0 (default) the CRL check will not be performed by the class. When set to 1, it will attempt to perform the CRL check, but will continue without an error if the server's certificate does not support CRL. When set to 2, it will perform the CRL check and will throw an error if CRL is not supported.

This configuration setting is only supported in the Java, C#, and C++ editions. In the C++ edition, it is only supported on Windows operating systems.

SSLCheckOCSP:   Whether to use OCSP to check the status of the server certificate.

This setting specifies whether the class will use OCSP to check the validity of the server certificate. If set to 1 or 2, the class will first obtain the OCSP URL from the server certificate's OCSP extension. The class will then locate the issuing certificate and make an HTTP request to the OCSP endpoint to check the validity of the server's certificate. If the certificate has been revoked or any other issues are found during validation the class fails with an error.

When set to 0 (default) the class will not perform an OCSP check. When set to 1, it will attempt to perform the OCSP check, but will continue without an error if the server's certificate does not support OCSP. When set to 2, it will perform the OCSP check and will throw an error if OCSP is not supported.

This configuration setting is only supported in the Java, C#, and C++ editions. In the C++ edition, it is only supported on Windows operating systems.

SSLCipherStrength:   The minimum cipher strength used for bulk encryption.

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

Please note that this setting contains the minimum cipher strength requested from the security library. The actual cipher strength used for the connection is shown by the SSLStatus event.

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

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

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

The enabled cipher suites to be used in SSL negotiation.

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

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

Multiple cipher suites are separated by semicolons.

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

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

  • TLS_AES_256_GCM_SHA384
  • TLS_CHACHA20_POLY1305_SHA256
  • TLS_AES_128_GCM_SHA256

SSLEnabledCipherSuites is used together with SSLCipherStrength.

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

Used to enable/disable the supported security protocols.

Not all supported protocols are enabled by default (the value of this setting is 4032). If you want more granular control over the enabled protocols, you can set this property to the binary 'OR' of one or more of the following values:

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

SSLEnabledProtocols - TLS 1.3 Notes

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

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

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

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

SSLEnabledProtocols: SSL2 and SSL3 Notes:

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

SSLEnableRenegotiation:   Whether the renegotiation_info SSL extension is supported.

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

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

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

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

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

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

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

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

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

SSLNegotiatedCipher:   Returns the negotiated cipher suite.

Returns the cipher suite negotiated during the SSL handshake.

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

SSLNegotiatedCipherStrength:   Returns the negotiated cipher suite strength.

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

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

SSLNegotiatedCipherSuite:   Returns the negotiated cipher suite.

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

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

SSLNegotiatedKeyExchange:   Returns the negotiated key exchange algorithm.

Returns the key exchange algorithm negotiated during the SSL handshake.

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

SSLNegotiatedKeyExchangeStrength:   Returns the negotiated key exchange algorithm strength.

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

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

SSLNegotiatedVersion:   Returns the negotiated protocol version.

Returns the protocol version negotiated during the SSL handshake.

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

SSLSecurityFlags:   Flags that control certificate verification.

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

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

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

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

This setting optionally specifies one or more CA certificates to be used when verifying the server certificate. When verifying the server's certificate the certificates trusted by the system will be used as part of the verification process. If the server's CA certificates are not installed to the trusted system store, they may be specified here so they are included when performing the verification process. This setting should only be set if the server's CA certificates are not already trusted on the system and cannot be installed to the trusted system store.

The value of this setting is a newline (CrLf) separated list of certificates. For instance:

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

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

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

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

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

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

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

TLS12SupportedGroups:   The supported groups for ECC.

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

The default value is ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1.

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

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

TLS13KeyShareGroups:   The groups for which to pregenerate key shares.

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

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

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

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

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

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

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

TLS13SignatureAlgorithms:   The allowed certificate signature algorithms.

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

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

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

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

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

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

Socket Config Settings

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

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

Note: This option is not valid for UDP ports.

FirewallData:   Used to send extra data to the firewall.

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

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

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

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

OutBufferSize:   The size in bytes of the outgoing queue of the socket.

This is the size of an internal queue in the TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be sending. Increasing the value of the OutBufferSize setting can provide significant improvements in performance in some cases.

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

Base Config Settings

BuildInfo:   Information about the product's build.

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

LicenseInfo:   Information about the current license.

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

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

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

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

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

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

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

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

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 FIPS, while all the 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 which 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 only applicable 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.
