AS4Server Component

Properties Methods Events Config Settings Errors

The AS4Server component implements an AS4 / ebHandler.

Syntax

TibeAS4Server

Remarks

The AS4Server component implements server-side processing of AS4 messages. It may be used to receive files form a client (push), respond to a client's request for files (pull), and also handles generating and verifying receipts.

The component is designed to be easily integrated into a HTTP server, such as ASP.NET, but may also be used outside of a web server. The examples below assume the component is used within an environment where there is an HTTP context.

To begin, when a request is received first call ReadRequest. This reads the AS4 request from the content of the Request (and optionally the RequestHeadersString) property. Alternatively the request data may be passed directly to the component by specifying calling SetRequestStream. After calling ReadRequest the following properties may be checked:

AgreementRef
AS4From
AS4To
ConversationId
EDIData
Errors
IncomingReceipt
MessageId
MessageProperties
MPC
Service
ServiceAction
ServiceType

The first step after calling ReadRequest is to determine if the client is sending files (push) or requesting files (pull). To determine this check the value of AgreementRef and MPC. For instance: if (server.AgreementRef == "" && server.MPC != "") { //The client is requesting files from the specified MPC //No other relevant properties are populated } else //AgreementRef is not empty, and MPC is empty { //The client is sending files. AgreementRef is populated with the agreement reference. //AS4From, AS4To, ConversationId, etc are populated }

Determining if the request contains an asynchronous receipt from a previous transmission may also be done at this time by checking the IncomingReceipt property's Content property. If it is populated a receipt is present. To verify the receipt set AsyncReceiptInfoDir to the directory where information about the message was originally stored and call VerifyReceipt. If the receipt is signed SignerCert must also be set. See the section below and also SendFiles for more details.

Once information about the request is determined the component may then be configured to respond appropriately depending on the operation.

Receiving Files and Sending a Receipt

When receiving files first check the AgreementRef, AS4From, and AS4To properties to determine who is sending the files and with what previously agreed upon configuration. Once this is known, if the request is signed and encrypted set Certificate to the decryption certificate and SignerCert to the public certificate used for signature verification. IncomingDirectory may optionally be set to automatically store the incoming files. //Process incoming files and send a signed receipt server.ReadRequest(); //Inspect values from the request in order to load appropriate certificates etc. //Console.WriteLine(server.AgreementRef); //Console.WriteLine(server.AS4From.Id); //Console.WriteLine(server.AS4To.Id);) server.IncomingDirectory = "..\\MyFiles"; //Our private certificate. Used to decrypt the incoming file server.Certificate = new Certificate(CertStoreTypes.cstPFXFile, Path.Combine(Request.PhysicalApplicationPath, "..\\files\\CompanyB.pfx"), "password", "*"); //Partner's public certificate. Used to verify the signature on the incoming message and files. server.SignerCert = new Certificate(Path.Combine(Request.PhysicalApplicationPath, "..\\files\\CompanyA.cer")); server.ParseRequest(); server.ReceiptReplyMode = As4serverReceiptReplyModes.rrmSync; //Our private certificate. Used to sign the receipt. server.SigningCert = new Certificate(CertStoreTypes.cstPFXFile, Path.Combine(Request.PhysicalApplicationPath, "..\\files\\CompanyB.pfx"), "password", "*"); server.SendResponse(); //Sends the receipt Receiving Files and Sending an Asynchronous Receipt

Receipts may be sent in the response (synchronous) or at a later time (asynchronous). If the agreement specifies that the receipt be sent asynchronously the following steps may be taken to send the receipt.

After calling ReadRequest the ReceiptReplyMode may be set to indicate the receipt will be returned asynchronously. After calling ParseRequest call SendAckResponse to send back a HTTP 200 OK to the client. The receipt may then be returned later.

To send an asynchronous receipt AS4Client may be used. This can be sent to the partner's web site, or bundled with a later response (depending on the agreement made between the parties). In the example below AS4Client is used to send the receipt to the other party's web site.

//Process incoming files and send an asynchronous receipt server.ReadRequest(); //Inspect values from the request in order to load appropriate certificates etc. //Console.WriteLine(server.AgreementRef); //Console.WriteLine(server.AS4From.Id); //Console.WriteLine(server.AS4To.Id);) server.IncomingDirectory = "..\\MyFiles"; //Our private certificate. Used to decrypt the incoming file server.Certificate = new Certificate(CertStoreTypes.cstPFXFile, Path.Combine(Request.PhysicalApplicationPath, "..\\files\\CompanyB.pfx"), "password", "*"); //Partner's public certificate. Used to verify the signature on the incoming message and files. server.SignerCert = new Certificate(Path.Combine(Request.PhysicalApplicationPath, "..\\files\\CompanyA.cer")); server.ParseRequest(); server.ReceiptReplyMode = As4serverReceiptReplyModes.rrmAsync; //Our private certificate. Used to sign the receipt. server.SigningCert = new Certificate(CertStoreTypes.cstPFXFile, Path.Combine(Request.PhysicalApplicationPath, "..\\files\\CompanyB.pfx"), "password", "*"); server.SendAckResponse(); //Sends an ack, but not the receipt At this point Receipt is populated with the receipt to be sent. Store the Receipt's Content and RefToMessageId values for use when sending the receipt later. Sending a receipt can be done with AS4Client.

//Send an asynchronous receipt client.URL = ""http://www.company.com:9090/msh""; client.Receipt = new EBReceipt(server.Receipt.RefToMessageId, server.Receipt.Content); client.ReceiptReplyMode = As4clientReceiptReplyModes.rrmAsync; client.SendReceipt();

Sending Files

To process a request to send files first check the MPC property. This holds the Message Partition Channel (MPC) from which the client would like to receive files. Next, set AgreementRef, AS4From, AS4To. Check IncomingReceipt to determine if the request has a bundled receipt. If it does VerifyReceipt can be called to verify the receipt.

Note: If the client requests files from the default MPC then MPC may be empty. See MessageType for details.

If the client makes use of UsernameToken authentication the TokenAuthentication event will fire when processing the request.

To send files back to the client simply set EDIData to the files you wish to send. When SendResponse is called the files will be sent back to the client.

//Process a request to send files (pull) //Holds information from the original send so that receipts can be verified later server.AsyncReceiptInfoDir = Path.Combine(Request.PhysicalApplicationPath, "..\\temp\\ReceiptInfoDir") server.Profile = As4serverProfiles.ebpfENTSOG; server.ReadRequest(); //The receipt may be signed depending upon the AgreementRef server.SignerCert = new Certificate(Path.Combine(Request.PhysicalApplicationPath, "..\\files\\CompanyA.cer")); //If the request has a bundled receipt verify it first if (!string.IsNullOrEmpty(server.IncomingReceipt.Content)) { server.VerifyReceipt(); } //If the request is a pull request (MPC is set) if (server.AgreementRef == "" && server.MPC != "") { server.AgreementRef = "http://agreements.company.com/pull_files"; server.AS4From.Id = "org:holodeckb2b:example:company:B"; server.AS4From.Role = "Sender"; server.AS4To.Id = "org:holodeckb2b:example:company:A"; server.AS4To.Role = "Receiver"; server.ReceiptReplyMode = As4serverReceiptReplyModes.rrmAsync; //Our private certificate. Used to sign the message and files. server.SigningCert = new Certificate(CertStoreTypes.cstPFXFile, Path.Combine(Request.PhysicalApplicationPath, "..\\files\\CompanyB.pfx"), "password", "*"); //Partner's public certificate. Used to encrypt files. server.RecipientCerts.Add(new Certificate(Path.Combine(Request.PhysicalApplicationPath, "..\\files\\CompanyA.cer"))); EBData data = new EBData(); data.EDIType = "text/xml"; data.Data = "<test>Hello AS4 World!</test>"; server.EDIData.Add(data); server.SendResponse(); }

Processing Receipts

Any incoming request may potentially include a receipt. The request may be a receipt by itself, or it may be bundled with another type of request (send/receive). When initially sending files AsyncReceiptInfoDir may be set to store data about the original message on disk for use when verifying the receipt. If this is not desired manually store the OriginalSOAPMessage and OriginalSOAPMessageId instead.

To detect if an incoming request contains a receipt simply check the IncomingReceipt property's Content property. If it is populated the request includes a receipt. Set AsyncReceiptInfoDir to the same location as when the file was originally sent. Or alternatively set OriginalSOAPMessage and OriginalSOAPMessageId properties to the original values.

If the receipt is signed set SignerCert to the public certificate which will be used to verify the signature. Lastly call VerifyReceipt. This will perform any signature verification and verify the receipt content as well, matching it to the original message values.

server.ReadRequest(); //The receipt may be signed depending upon the AgreementRef server.SignerCert = new Certificate(Path.Combine(Request.PhysicalApplicationPath, "..\\files\\CompanyA.cer")); //If the request contains a receipt verify it if (!string.IsNullOrEmpty(server.IncomingReceipt.Content)) { server.VerifyReceipt(); }

AgreementRef Property (AS4Server Component)

The agreement reference.

Syntax

property AgreementRef: String read get_AgreementRef write set_AgreementRef;

Default Value

Remarks

This property holds a value identifying the agreement between the two parties. The agreement is made outside the scope of the request and response and governs details about the interaction including reply mode, signing and encryption options, etc.

The value of this property should be set to a mutually agreed upon identifier. Both parties will use this value know what the expected requirements are for a particular request or response.

The format of this value is typically a URI, such as "http://mycompany.com/agreement_01" but can be any unique string that both parties are configured to accept. Another common format is the concatenation of the AS4From and AS4To values.

This value corresponds to the ebMS element "eb:Messaging/eb:UserMessage/eb:CollaborationInfo/eb:AgreementRef"

AS4From Property (AS4Server Component)

Defines information about the originating party.

Syntax

property AS4From: TibeEBPartyInfo read get_AS4From write set_AS4From;

Remarks

This property defines information about the party that originates the message.

Please refer to the EBPartyInfo type for a complete list of fields.

AS4To Property (AS4Server Component)

Defines information about the responding party.

Syntax

property AS4To: TibeEBPartyInfo read get_AS4To write set_AS4To;

Remarks

This property defines information about the party that receives the message.

Please refer to the EBPartyInfo type for a complete list of fields.

AsyncReceiptInfoDir Property (AS4Server Component)

A directory to hold information used for asynchronous receipt verification.

Syntax

property AsyncReceiptInfoDir: String read get_AsyncReceiptInfoDir write set_AsyncReceiptInfoDir;

Default Value

Remarks

This setting specifies a directory which holds information about the original message that was sent.

When sending files and requesting asynchronous receipts set this directory to a location where data can be stored. When the receipt is later received this property should be set so original message information can be read in order to verify the receipt.

As an alternative the original message information may be manually stored by saving the values of OriginalSOAPMessage and OriginalSOAPMessageId after sending a file. In this case OriginalSOAPMessage and OriginalSOAPMessageId should be populated before verifying the receipt.

See the VerifyReceipt method of AS4Server for more details about verifying asynchronous receipts.

Certificate Property (AS4Server Component)

The certificate with private key used for decryption.

Syntax

property Certificate: TibeCertificate read get_Certificate write set_Certificate;

Remarks

This property specifies a certificate with private key. It is used to decrypt received files.

Please refer to the Certificate type for a complete list of fields.

ConversationId Property (AS4Server Component)

The Conversation Id of the message.

Syntax

property ConversationId: String read get_ConversationId write set_ConversationId;

Default Value

Remarks

This property specifies an Id that may be used to identify a set of related messages. This is required and if a value is not specified one will automatically be created.

Note: When Profile is set to ebpfENTSOG this value will always be empty.

This value corresponds to the ebMS element "eb:Messaging/eb:UserMessage/eb:CollaborationInfo/eb:ConversationId"

EDIData Property (AS4Server Component)

The EDI data.

Syntax

property EData: TibeEBDataList read get_EDIData write set_EDIData;

Please refer to the EBError type for a complete list of fields.

IncomingDirectory Property (AS4Server Component)

The directory to which incoming files are saved.

Syntax

property IncomingDirectory: String read get_IncomingDirectory write set_IncomingDirectory;

Default Value

Remarks

If IncomingDirectory is set, the received files will be stored in the specified directory. If a filename is specified in the EDI message, the component 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.

This property is optional, if not set file data will be stored in EDIData.

IncomingReceipt Property (AS4Server Component)

The receipt included with the request.

Syntax

property IncomingReceipt: TibeEBReceipt read get_IncomingReceipt;

Remarks

This property is populated by ReadRequest if the incoming request contains a receipt. Receipts received in this manner are always asynchronous and must be verified by calling VerifyReceipt.

Processing Receipts

This property is read-only.

Please refer to the EBReceipt type for a complete list of fields.

LogDirectory Property (AS4Server Component)

The path to a directory for logging.

Syntax

property LogDirectory: String read get_LogDirectory write set_LogDirectory;

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 component will log the complete text of the outgoing request and the incoming response.

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


Status (.log)	Contains information about the steps taken during processing.
Request (.out)	Contains the raw request/response that is sent by the component.
Response (.in)	Contains the raw request/response that is received by the component.
Incoming ebXML (.ieb)	Contains the incoming ebXML message.
Outgoing ebXML (.oeb)	Contains the outgoing ebXML message.

One or more of these log files 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 component will attempt to create the directory. The following macros are supported:


%AS4From%	The AS4From value in the message. Note that invalid filename characters will be replaced with the `_` character.
%MessageId%	The MessageId of the transmission, after it is generated.
%Date:format%	Format is a platform-specific date/time formatting string. For example:

The filenames will be chosen automatically by the component. 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.

LogFile Property (AS4Server Component)

The log file written.

Syntax

property LogFile: String read get_LogFile;

Default Value

Remarks

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

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


Status (.log)	Contains information about the steps taken during processing.
Request (.out)	Contains the raw request/response that is sent by the component.
Response (.in)	Contains the raw request/response that is received by the component.
Incoming ebXML (.ieb)	Contains the incoming ebXML message.
Outgoing ebXML (.oeb)	Contains the outgoing ebXML message.


%AS4From%	The AS4From value in the message. Note that invalid filename characters will be replaced with the `_` character.
%MessageId%	The MessageId of the transmission, after it is generated.
%Date:format%	Format is a platform-specific date/time formatting string. For example:

If logs cannot be written an exception will be thrown.

This property is read-only.

MessageId Property (AS4Server Component)

The unique Id of the message.

Syntax

property MessageId: String read get_MessageId write set_MessageId;

Default Value

Remarks

This property defines the unique Id of the message. When sending files the component will automatically generate a value in the format "GUID@nsoftware". When receiving files the Id will be populated with the value read from the message.

In most cases there is no need to set this value, however if a file needs to be retransmitted using the same message Id for reliability this may be set. In AS4Client this may be set before calling SendFiles. In AS4Server this may be set after calling ReadRequest and before calling SendResponse.

This property is not available at design time.

MessageProperties Property (AS4Server Component)

A collection of message properties.

Syntax

property MessageProperties: TibeEBPropertyList read get_MessageProperties write set_MessageProperties;

Remarks

This collection specifies the message level properties that are sent with the message. This may be used to add additional values. The semantics of the values are beyond the scope of AS4, but this may be used for values that assist with processing, or other user-defined use cases.

These properties may be populated before sending a message, and are populated after parsing an incoming message.

Sending

When sending a message any number of properties may be added. The PropertyType property is optional. For instance: //using fields client.MessageProperties.Add(new EBProperty()); client.MessageProperties[0].Name = "name1"; client.MessageProperties[0].Value = "value1"; client.MessageProperties[0].PropertyType = "string"; //optional //using constructor client.MessageProperties.Add(new EBProperty("name2", "value2"));

Receiving

When receiving a message the properties may be read from this collection. For instance: for (int i = 0; i < server.MessageProperties.Count; i++) { Console.WriteLine(server.MessageProperties[i].Name + ": " + server.MessageProperties[i].Value); }

This value corresponds to the ebMS element "eb:Messaging/eb:UserMessage/eb:MessageProperties""

Please refer to the EBProperty type for a complete list of fields.

MPC Property (AS4Server Component)

The MPC (Message Partition Channel) from which files are requested.

Syntax

property MPC: String read get_MPC write set_MPC;

Default Value

Remarks

This property specifies the MPC (Message Partition Channel) from which to receive files. This must be set before calling ReceiveFiles. The value specified here must be known to the other party.

When left unspecified this indicates the default MPC.

This value corresponds to the ebMS element "eb:Messaging/eb:SignalMessage/eb:PullRequest/@mpc"

This property defines the MPC (Message Partition Channel) from which the client requests files. This is populated after calling ReadRequest and is used to determine from which channel to provide files to the client.

This value corresponds to the ebMS element "eb:Messaging/eb:SignalMessage/eb:PullRequest/@mpc"

OriginalSOAPMessage Property (AS4Server Component)

The original SOAP message used to verify the receipt.

Syntax

property OriginalSOAPMessage: String read get_OriginalSOAPMessage write set_OriginalSOAPMessage;

Default Value

Remarks

OriginalSOAPMessage and OriginalSOAPMessageId may be used as an alternative to AsyncReceiptInfoDir when verifying receipts.

If AsyncReceiptInfoDir is not set when the original message is sent, these values will be populated after the send and the values should be saved.

Before verifying the receipt set these properties to their original values.

This property is not available at design time.

OriginalSOAPMessageId Property (AS4Server Component)

The original SOAP message Id used to verify the receipt.

Syntax

property OriginalSOAPMessageId: String read get_OriginalSOAPMessageId write set_OriginalSOAPMessageId;

Receipt Property (AS4Server Component)

The receipt of a message.

Syntax

property Receipt: TibeEBReceipt read get_Receipt write set_Receipt;

Remarks

This property holds the receipt of a message. When receiving files from a client this property is populated with the receipt to be sent back after calling ParseRequest.

To deliver the receipt in the same connection (synchronously) call SendResponse. To deliver the receipt asynchronously use the SendReceipt method of AS4Client.

Note: This property is only applicable for receipts generated in response to received files. For information on processing incoming asynchronous receipts see IncomingReceipt and VerifyReceipt.

Please refer to the EBReceipt type for a complete list of fields.

ReceiptReplyMode Property (AS4Server Component)

The expected receipt reply mode.

Syntax

property ReceiptReplyMode: TibeTReceiptReplyModes read get_ReceiptReplyMode write set_ReceiptReplyMode;

TibeTReceiptReplyModes = (
  rrmSync,
  rrmAsync,
  rrmNone
);

Default Value

rrmSync

Remarks

This setting tells the component how to expect or deliver a receipt. Possible values are:


0 (rrmSync - default)	The receipt is expected in the response to the request. This is only valid when sending files from a client to a server (push). This is a synchronous receipt (the receipt is returned in the same HTTP connection).
1 (rrmAsync)	The receipt is returned at a later time. The receipt may be returned by itself in a separate connection, or may be bundled with a subsequent request. This is the only available mode when receiving files from a server (pull).
2 (rrmNone)	No receipt is expected.

It is important to always set this property to the correct value in both AS4Client and AS4Server, whether sending or receiving, so the component can build a valid message. This should be set to the previously agreed upon value between the parties in the agreement identified by AgreementRef

RecipientCerts Property (AS4Server Component)

The public certificate used to encrypt files when sending.

Syntax

property RecipientCerts: TibeCertificateList read get_RecipientCerts write set_RecipientCerts;

This property is only applicable when Profile is set to ebpfEDelivery. The eDelivery profile supports the Two-Way/Push-and-Push MEP (Message Exchange Pattern), where sending a file can be in reference to a previously received file. In this case RefToMessageId specifies the Id of the previously received message to which this send is in reference.

When sending with AS4Client this should only be set when using the eDelivery profile and need to explicitly specify the RefToMessageId value as per the Two-Way/Push-And-Push MEP.

When receiving with AS4Server this may be read after receiving a message.

Config Method (AS4Server Component)

Sets or retrieves a configuration setting.

Syntax

function Config(ConfigurationString: String): String;

Remarks

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

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, 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.

DoEvents Method (AS4Server Component)

This method should be called after calling ReadRequest and specifying any necessary certificates for the operation to complete successfully.

Receiving Files and Sending a Receipt

Sending Files

Note: If the client requests files from the default MPC then MPC may be empty. See MessageType for details.

If the client makes use of UsernameToken authentication the TokenAuthentication event will fire when processing the request.

To send files back to the client simply set EDIData to the files you wish to send. When SendResponse is called the files will be sent back to the client.

ReadRequest Method (AS4Server Component)

Reads the AS4 request.

Syntax

procedure ReadRequest();

Once information about the request is determined the component may then be configured to respond appropriately depending on the operation.

If the client makes use of UsernameToken authentication the TokenAuthentication event will fire when processing the request.

To send files back to the client simply set EDIData to the files you wish to send. When SendResponse is called the files will be sent back to the client.

VerifyReceipt Method (AS4Server Component)

Verifies a received receipt.

Syntax

procedure VerifyReceipt();

Remarks

This method is used to verify asynchronous receipts held in IncomingReceipt.

Processing Receipts

Error Event (AS4Server Component)

Fired when information is available about errors during data delivery.

Syntax

type TErrorEvent = procedure (
  Sender: TObject;
  ErrorCode: Integer;
  const Description: String
) of Object;

property OnError: TErrorEvent read FOnError write FOnError;

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the component raises an exception.

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 (AS4Server Component)

Fired with log information while processing a message.

Syntax

type TLogEvent = procedure (

) of Object;

property OnLog: TLogEvent read FOnLog write FOnLog;

Remarks

This event fires once for each log message generated by the component. 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:


"INFO"	Information about the status of the process.
"ERROR"	An error was encountered.
"DEBUG"	Debug information.

RecipientInfo Event (AS4Server Component)

Fired for each recipient certificate of the encrypted message.

Syntax

type TRecipientInfoEvent = procedure (
  Sender: TObject;
  const Issuer: String;
  const SerialNumber: String;
  const SubjectKeyIdentifier: String;
  const EncryptionAlgorithm: String
) of Object;

property OnRecipientInfo: TRecipientInfoEvent read FOnRecipientInfo write FOnRecipientInfo;

Remarks

When ParseRequest is called and the file is encrypted, this event will fire for each recipient certificate for which the file was encrypted.

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"

  const Issuer: String;
  const SerialNumber: String;
  const SubjectKeyIdentifier: String;
  const CertEncoded: String;
  const CertEncodedB: TBytes
) of Object;

property OnSignerCertInfo: TSignerCertInfoEvent read FOnSignerCertInfo write FOnSignerCertInfo;

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 component 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.

TokenAuthentication Event (AS4Server Component)

Fired when the client makes use of UsernameToken authentication.

Syntax

type TTokenAuthenticationEvent = procedure (
  Sender: TObject;
  const User: String;
  var Password: String;
  const PasswordType: String;
  var Accept: Boolean
) of Object;

property OnTokenAuthentication: TTokenAuthenticationEvent read FOnTokenAuthentication write FOnTokenAuthentication;

Remarks

This event fires when a client sends a request that includes UsernameToken authentication. This is typically only used by clients initiating a pull request.

User identifies the user.

Password should be set from within the event if PasswordType is 0 (digest). This parameter can be read when PasswordType is 1 (text).

PasswordType specifies the type of password. Possible values are:

0 (Digest)
1 (Text)

Accept may be set to manually accept the request.

When PasswordType is 0 (Digest) set the Password parameter to the plaintext password. Do not set Accept The component will hash the provided password value and compare it to the value in the request. If it matched the component will accept the request. If it does not match the component will populate Errors with an error indicating authentication has failed.

When PasswordType is 1 (Text) the Password parameter will hold the exact value received in the request. Inspect Password and determine whether to accept the request. To accept the request set Accept to True.

After this event fires if authentication failed Errors will contain an appropriate error. Send the errors back to the client by calling SendResponse.

Certificate Type

This is the digital certificate being used.

Default Value: ""

The certificate (PEM/Base64 encoded). This property is used to assign a specific certificate. The Store and Subject properties also may be used to specify a certificate.

Constructors

constructor Create();

Creates a instance whose properties can be set. This is useful for use with when generating new certificates.

constructor Create(valEncoded: TBytes);

Parses Encoded as an X.509 public key.

constructor Create(valStoreType: TibeCertStoreTypes; valStore: String; valStorePassword: String; valSubject: String);

StoreType identifies the type of certificate store to use. See for descriptions of the different certificate stores. Store is a file containing the certificate store. StorePassword is the password used to protect the store.

After the store has been successfully opened, the component will attempt to find the certificate identified by Subject . This can be either a complete or a substring match of the X.509 certificate's subject Distinguished Name (DN). The Subject parameter can also take an MD5, SHA-1, or SHA-256 thumbprint of the certificate to load in a "Thumbprint=value" format.

constructor Create(valStoreType: TibeCertStoreTypes; valStore: TBytes; valStorePassword: String; valSubject: String);

StoreType identifies the type of certificate store to use. See for descriptions of the different certificate stores. Store is a byte array containing the certificate data. StorePassword is the password used to protect the store.

When receiving EDI data, Name will be read out of the "filename" attribute of the inbound request's Content-Disposition MIME header.

PropertyCount
Integer
Default Value: 0

The number of properties for this file.

Each file may contain zero or more properties associated with it. This property, in conjunction with PropertyIndex, PropertyName, and PropertyValue can be used to specify properties when sending and read properties when receiving.

Sending

When sending files to add properties set PropertyCount to specify the number of properties. Then set PropertyIndex to select the property. Set PropertyName and PropertyValue to define the values for the property at PropertyIndex. For instance: data = new EBData(); data.EDIType = "image/jpeg"; data.FileName = "..\\1.jpg"; data.Name = "1.jpg"; data.PropertyCount = 2; //Define two properties data.PropertyIndex = 0; //Select the first property data.PropertyName = "name1"; data.PropertyValue = "value1"; data.PropertyIndex = 1; //Select the second property data.PropertyName = "name2"; data.PropertyValue = "value2";

Receiving

When receiving files these properties may be queried to retrieve the values set by the sender. Inspect PropertyCount to obtain the number of properties. Next set PropertyIndex to select a property and query PropertyName and PropertyValue. For instance:

for (int i = 0; i < server.EDIData[0].PropertyCount;i++) { server.EDIData[0].PropertyIndex = i; Console.WriteLine(server.EDIData[0].PropertyName + ": " + server.EDIData[0].PropertyValue); }

Config Settings (AS4Server Component)

The component 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 component, access to these internal properties is provided through the Config method.

AS4Server Config Settings

AgreementRefPMode: AgreementRef PMode of message.

This optional setting allows for the association of a message with a particular P-Mode. If specified it should be the PMode.ID parameter.

This value corresponds to the ebMS element "eb:Messaging/eb:UserMessage/eb:CollaborationInfo/eb:AgreementRef/@pmode"

AgreementRefType: The type of AgreementRef.

This optional setting indicates how parties should interpret the value of AgreementRef. The semantics of this value should be decided upon between the parties.

This value corresponds to the ebMS element "eb:Messaging/eb:UserMessage/eb:CollaborationInfo/eb:AgreementRef/@type"

AllowWarnings: Whether warnings are interpreted as fatal errors.

When set to False (default) any ebMS level error returned by the other party will be considered an error and cause an exception. When set to True the severity of the ebMS error will be inspected. If the severity is "warning" it will not cause an exception. In this case Errors will still be populated with the error details.

AttachXMLFiles: Whether to send XML files as attachments or within the SOAP body.

This setting specifies whether XML files are included as attachments or within the SOAP body.

This setting is only applicable when the first file specified in EDIData is of type "text/xml" or "application/xml". In addition this is only applicable when Profile is set to Standard.

If set to True (default), the file will be sent as an attachment. This allows the filename to be preserved and the file is sent as a separate MIME part. If set to False and the criteria above are met then the file will be sent within the SOAP body. In this case the filename cannot be preserved normally.

The default value is True.

CloseStreamAfterProcessing: Whether to close the input or output stream after processing.

This setting specifies whether the input or output stream will be closed after processing. This may be set to False to leave the stream open for further operations. The default value is True and the stream will be by the component.

CompressXMLPayloads: Whether to compress XML data.

When CompressionFormat is set to GZIP all EDIData parts will be compressed. To exclude XML payloads with EDIType values of "text/xml" or "application/xml" from being compressed set this value to False. By default this is True and all attachments will be compressed.

Note: When Profile is set to Standard the first EDIData part will be included in the SOAP body if the EDIType is "text/xml" or "application/xml". In that case since the data is included in the SOAP body it will not be compressed. When Profile is set to ENTSOG all EDIData parts are compressed.

ContentTransferEncoding: The content encoding of the payload data.

This setting can be used to specify the content encoding of the payload data of the AS4 message. This is set to binary (4) by default. Possible values for the this field are:


Base64 (2)	Base64 encoding of binary data.
Binary (4)	Binary data without any encoding.

DetectDuplicates: Whether to detect duplicate messages when receiving.

Whether to detect duplicate messages. If set to True LogDirectory must be set. When a file is received the component will store a file containing the MessageId of the received file. When additional files are received the component will scan the LogDirectory to see if a file with the same MessageId has already been received. If a duplicate is detected an entry is added to the .log file and Log fires.

The default value depends on the Profile. For the Standard profile the default value is False. When Profile is set to ENTSOG this value is set to True.

EBPrefix: Specifies the prefix to use for messaging.

This setting specified the prefix to use for messaging. The default value is "eb3" and will result in values such as: eb3:Messaging It may be desirable to set this to another value such as "eb" so client and server sides both use the same prefix.

EDIDataPartId[i]: Specified the part Id at the given index.

This setting may be used to specify the value for each EDIData part that is present in the message. By default the component will generate a unique value. For instance:

<eb3:PartInfo href="cid:_de48eece-d1d8-4823-8a63-d3a8d14dc1a8@nsoftware">

In some cases it may be desired or necessary to specify a user-defined value. For instance:

<eb3:PartInfo href="cid:mypart@myhost">

After adding the part to EDIData the Id may be specified by setting:

AS4Component.Config("EDIDataPartId[0]=mypart@myhost");

This setting is also populated with the parsed Ids after receiving a message.

EnableTokenReferenceTokenType: Whether to include the TokenType attribute in a SecurityTokenReference element.

When this configuration setting is enabled, messages will include the TokenType attribute in any SecurityTokenReference elements. It will also add a namespace declaration for Web Services Security Version 1.1 (http://docs.oasis-open.org/wss/oasis-wss-wssecurity-secext-1.1.xsd). Note: This setting is not compatible with the X509 security token format.

EncryptionSecurityTokenFormat: The format to use for the security token when encryption.

This setting specifies the security token format that is included in the message when encrypting. This setting should only be set if there is a specific reason to do so. This specifies the reference type in the SecurityTokenReference element applicable to the encrypted data. Possible values are:


0 (X509 - default)	X509 data including the certificate's issuer name and issuer serial number is included in the X509Data element.
1 (Binary)	A binary security token holds the base64 encoded contents of the public certificate and is referenced from within the Reference element.
2 (Subject Key Identifier)	The X509 subject key identifier is included in the KeyIdentifier element.
3 (X509PKIPathv1)	A binary security token holds the base64 encoded ordered list of X509 public certificates and is referenced from within the Reference element.

The default value is 0 (X509) and should not be changed unless there is a specific reason to do so.

Note: The default value when Profile is set to eDelivery is 1 (Binary).

FilenameProperty: Defines a part property to hold the filename.

This setting specifies the PropertyName that will hold the name of the file. This may be used to preserve filenames. Both the client and server must agree on the name of the property that will be used to hold the filename.

This is helpful in the case where Profile is set to ebpfStandard and the first file being sent is of type "text/xml" or "application/xml". In that case the file content is included in the SOAP body and there is no standard mechanism for preserving the filename.

When set the component will automatically populate the property when sending files and will read the filename from this property when receiving files.

By default this is not specified.

Note: The filenames will always be preserved within the MIME header attributes whenever possible regardless of whether this setting is specified.

ForceSigningCert: Whether to force only the SigningCert to be used for signing.

When set to False the component will first check SigningCert for a certificate to use for signing operations. If SigningCert is not specified it will use the certificate specified in Certificate.

If set to True (default) the component will only attempt to use the certificate specified by SigningCert. If SigningCert is not specified signing will not be attempted.

FromId[i]: The Id of the party specified by AS4From.

This setting sets the Id of the party specified by AS4From at the index specified here. This is only used when multiple Ids are set. See FromIdCount for more details.

FromIdCount: The number of Ids for the party specified by AS4From.

Multiple Ids may be specified for the AS4From party. This setting defines the total number of Ids. This is used in conjunction with FromId and FromIdType. For instance: component.Config("FromIdCount=2"); component.Config("FromId[0]=id1"); component.Config("FromIdType[0]=mytype"); component.Config("FromId[1]=id2");

When receiving a message with multiple Ids, query these settings to read the values.

By default this value is unspecified and only a single Id is used as specified in the Id property of AS4From.

FromIdType[i]: The Id type of the party specified by AS4From.

This setting sets the Id type of the party specified by AS4From at the index specified here. This is only used when multiple Ids are set. See FromIdCount for more details.

IdRight: A custom Id for the right side of the MessageId.

This setting may be used to specify a custom value for the right side of the MessageId that is generated by the component. By default the component will automatically generate message Ids in the format: 2a1546bd-d623-4e7f-bb8d-ddecfb4de51c@nsoftware This setting provides a way to replace the "nsoftware" value after the "@" symbol with another value.

KeyAgreementMethod: The agreement method used for KeyWrap encryption algorithms.

This setting specifies the agreement method used for KeyWrap encryption algorithms (KW-AES). The default is ECDH-ES, and other methods are not currently supported. Possible values are:


Value	Algorithm	Notes
DH	http://www.w3.org/2009/xmlenc11#dh	Not currently implemented.
DH-ES	http://www.w3.org/2009/xmlenc11#dh-es	Not currently implemented.
ECDH-ES	http://www.w3.org/2009/xmlenc11#ECDH-ES	Default when Profile is ebpfBDEW.
X25519	http://www.w3.org/2001/04/xmldsig-more#x25519	Default when Profile is ebpfENTSOG_V4 or ebpgEDelivery_V24.
X448	http://www.w3.org/2001/04/xmldsig-more#x448

KeyDerivationConcatKDFDigestMethod: The digest method used for the ConcatKDF key derivation method.

This is the digest method used when the ConcatKDF key derivation method is selected. In most cases this should not be changed. Only change this value if there is a specific reason to do so. Possible values are:

SHA512
SHA384
SHA256 (Default)
SHA224
SHA1

KeyDerivationMethod: The key derivation method used for KeyWrap encryption algorithms.

This setting specifies the derivation method used for KeyWrap encryption algorithms (KW-AES). Possible values are:


Value	Algorithm
ConcatKDF (Default)	http://www.w3.org/2009/xmlenc11#ConcatKDF
PBKDF2	http://www.w3.org/2009/xmlenc11#pbkdf2
HKDF	http://www.w3.org/2021/04/xmldsig-more#hkdf

KeyEncryptionAlgorithm: The algorithm used to encrypt the key.

This setting specifies the algorithm used to encrypt the key for this message. In most cases this should not be changed. Only change this value if there is a specific reason to do so. Possible values are:


Value	Algorithm	Notes
`RSA-OAEP-XMLENC11`	http://www.w3.org/2009/xmlenc11#rsa-oaep	This is used in the default configuration. Additionally if `RSA-OAEP` is specified this will be automatically used instead if OAEPMGF1HashAlgorithm is set to any value except `SHA1` or OAEPRSAHashAlgorithm is set to `SHA384` or `SHA512`.
`RSA-v1.5`	http://www.w3.org/2001/04/xmlenc#rsa-1_5	There are no conditions for the use of this algorithm. If specified it will be used regardless of other settings.
`RSA-OAEP`	http://www.w3.org/2001/04/xmlenc#rsa-oaep-mgf1p	This is used by default when OAEPMGF1HashAlgorithm is set to `SHA1` and OAEPRSAHashAlgorithm is set to `SHA1` or `SHA256`. This is only applicable under these conditions, it cannot override when `RSA-OAEP-XMLENC11` is used based on the OAEPMGF1HashAlgorithm and OAEPRSAHashAlgorithm values.
`KW-AES128`	http://www.w3.org/2001/04/xmlenc#kw-aes128	This is used by default if Profile is set to ebpfBDEW.
`KW-AES192`	http://www.w3.org/2001/04/xmlenc#kw-aes192
`KW-AES256`	http://www.w3.org/2001/04/xmlenc#kw-aes256

LogLevel: The level of information to log.

This setting specifies the level of detail that is logged to the Log event and to any log files on disk. Possible value are:


0 (Error)	Only errors are logged.
1 (Info - default)	Informational and errors are logged.
2 (Debug)	All information is logged including debug info.

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=Incoming, Outgoing, Log"). The default value is All. Possible values are:


Log	Contains information about the steps taken during processing. Also see LogLevel.
Incoming	Contains the raw request/response that is received by the component.
Outgoing	Contains the raw request/response that is sent by the component.
IncomingMessage	Contains the incoming ebXML message.
OutgoingMessage	Contains the outgoing ebXML message.
All (default)	All of the above

MessageType: Indicates the type of message received.

This property may be used to determine what type of message was received in a request. Requests may be used for multiple functions. For instance a request may contain a pull request and a receipt. This setting may be used as a bitmask to determine which combination of types are present. To inspect the message perform a binary 'AND' with one or more of the following values:


1	Pull Request (Receive Files)
2	User Message (Send Files)
4	Receipt
8	Error Message

For instance:

int requestType = Int32.Parse(AS4Server.Config("MessageType"));
if((requestType & 1) != 0)
  //The request contains a pull request

NormalizeIssuerSubject: Whether to normalize the certificate subject within the X509Data element.

If set to True (default) the component will normalize the X509IssuerName element within the request to conform to RFC 2253. If set to False the component will use a standard format used by other components within the toolkit, which may not be compatible with all other AS4 software.

The default value is True to maximize interoperability with other AS4 software.

OAEPMGF1HashAlgorithm: The MGF1 hash algorithm used when encrypting a key.

When encryption is enabled, this algorithm specifies the MGF1 hash algorithm used for the encryption key by RSA OAEP. Possible values are:

"SHA1"
"SHA224"
"SHA256" (default)
"SHA384"
"SHA512"

Note: If Profile is set to ENTSOG the MGF1HashAlgorithm will be set to "SHA256" by default.

OAEPParams: The hex encoded OAEP parameters to be used when encrypting a key.

This setting is optional and should only be specified if OAEP parameters need to be explicitly set. The value specified should be a hex string. By default this setting is unspecified.

OAEPRSAHashAlgorithm: The RSA hash algorithm used when encrypting a key.

When encryption is enabled, this algorithm specifies the RSA hash algorithm used for the encryption key. This may differ from the hash algorithm used to sign the AS4 message content. Possible values are:

"SHA1"
"SHA224"
"SHA256" (default)
"SHA384"
"SHA512"

ReferenceHashAlgorithm: The hash algorithm used to hash the data specified in the reference of a signature.

When signing the content being signed is referred to by a reference in the Signature element. This setting specifies the hash algorithm used when computing the reference digest. Possible values are:

"SHA1"
"SHA224"
"SHA256" (default)
"SHA384"
"SHA512"

RequireEncryption: Whether encryption is required when processing received messages.

This setting may be set to True to require that received messages are encrypted. When True if a message is received that is not encrypted the component will throw an exception. The default value is False.

RequireSignature: Whether a signature is required when processing received messages.

This setting may be set to True to require that received messages are signed. When True if a message is received that is not signed the component will throw an exception. The default value is False.

ResponseBody: The body for the AS4 response message.

When ResponseToString is set to true, the response body will be available via this setting after the SendResponse method is called. This config is read only.

ResponseFile: A file from which to read the response.

This setting specifies a file from which the response is read. This may be useful in cases where the response is not received directly by the component. For instance it may be useful in debugging. If ResponseHeaders is not specified they will be read from file.

ResponseHeaders: The headers for the AS4 response message.

When ResponseToString is set to true, the response headers will be available via this setting after the SendResponse method is called.

This setting may also be used in conjunction with ResponseFile to provide the request to the component. See ResponseFile for details.

ResponseToFile: Creates the AS4 response message on disk.

This setting allows for the AS4 response message to be created on disk without actually being sent. This is useful in certain situations to prepare the message where it is sent by a different transport mechanism at a later time. This should be set to a relative or absolute file path including the filename. When this is set, the SendResponse method will generate the response message and write it to the specified file.

ResponseToString: Creates the AS4 response message in memory.

This setting allows for the AS4 response message to be created in memory without actually being sent. This is useful in certain situations to prepare the message where it is sent by a different transport mechanism at a later time. This is false by default, but when set to true the SendResponse method will create the response headers and body in memory where they can be accessed via the ResponseHeaders and ResponseBody, respectively. Note that when this is used, the message encoding will be set to Base64 automatically.

RolloverCertStore: The certificate store for the rollover certificate.

The RolloverCert* configuration settings may be used to specify an additional certificate to use for decryption during a period of transition between private certificates in the application. This setting specifies the certificate store.

When specified the component will be able to decrypt messages that were encrypted with the corresponding public certificate of either Certificate or the RolloverCert* configuration settings.

RolloverCertStorePassword: The certificate store for the rollover certificate.

When specified the component will be able to decrypt messages that were encrypted with the corresponding public certificate of either Certificate or the RolloverCert* configuration settings.

RolloverCertStoreType: The certificate store for the rollover certificate.

When specified the component will be able to decrypt messages that were encrypted with the corresponding public certificate of either Certificate or the RolloverCert* configuration settings.

RolloverCertSubject: The certificate store for the rollover certificate.

When specified the component will be able to decrypt messages that were encrypted with the corresponding public certificate of either Certificate or the RolloverCert* configuration settings.

The certificate will be loaded after this setting is set, so it should be set after the other RolloverCert* settings.

SignatureHash: The hash algorithm used to hash the data specified in signature.

This setting is used to specify the signature hash algorithm. This is only applicable when Profile is set to ENTSOG v4 or eDelivery V2. Possible values are:

"SHA256" (default)

SignerCACert: The CA certificates that issued the signer certificate.

This setting may be set prior to signature verification when receiving messages that are signed using a certificate specified in the message itself as a BinarySecurityToken.

If this setting is specified, the component will verify the chain of the signer certificate against the CA list set in this setting. To specify one or more CA certificate prior to signature verification set this to the base64 encoded public certificate of each CA certificate. Each additional certificate can be added by prepending the data with a + character. If the value begins with a + the component will add the following value to an internal store of CA certificates. For instance: //Add the first CA certificate as4.Config("SignerCACert=MIICFDCCAX2g..."); //Add another CA certificate (Note the leading '+') as4.Config("SignerCACert=+MIICHDCCAYW...");

If the chain validation fails during signature verification the component raises an exception. If this setting is not specified no chain validation is performed.

SigningSecurityTokenFormat: The format to use for the security token when signing.

This setting specifies the security token format that is included in the message when signing. This setting should only be set if there is a specific reason to do so. This specifies the reference type in the SecurityTokenReference element applicable to the signed data. Possible values are:


0 (X509 - default)	X509 data including the certificate's issuer name and issuer serial number is included in the X509Data element.
1 (Binary)	A binary security token holds the base64 encoded contents of the public certificate and is referenced from within the Reference element.
2 (Subject Key Identifier)	The X509 subject key identifier is included in the KeyIdentifier element.
3 (X509PKIPathv1)	A binary security token holds the base64 encoded ordered list of X509 public certificates and is referenced from within the Reference element.

The default value is 0 (X509) and should not be changed unless there is a specific reason to do so.

Note: The default value when Profile is set to eDelivery is 1 (Binary).

TempPath: Where temporary files are optionally written.

When processing large files an excessive amount of memory may be used, leading to out-of-memory exceptions. To reduce the amount of memory used, partially encoded files can be written to a temporary directory. Set this to a folder on disk where temporary files may be written.

ToId[i]: The Id of the party specified by AS4To.

This setting sets the Id of the party specified by AS4To at the index specified here. This is only used when multiple Ids are set. See ToIdCount for more details.

ToIdCount: The number of Ids for the party specified by AS4To.

Multiple Ids may be specified for the AS4To party. This setting defines the total number of Ids. This is used in conjunction with ToId and ToIdType. For instance: component.Config("ToIdCount=2"); component.Config("ToId[0]=id1"); component.Config("ToIdType[0]=mytype"); component.Config("ToId[1]=id2");

When receiving a message with multiple Ids, query these settings to read the values.

By default this value is unspecified and only a single Id is used as specified in the Id property of AS4To.

ToIdType[i]: The Id type of the party specified by AS4To.

This setting sets the Id type of the party specified by AS4To at the index specified here. This is only used when multiple Ids are set. See ToIdCount for more details.

TransformReceipt: Whether to canonicalize the received receipt.

When a receipt is received this setting controls whether the value in Content is transformed.

When set to True (default) the component will perform canonicalize the receipt when it is received. This may be helpful if the value of Content is to be used in a later process where a valid XML document is required. When set to true (false by default), the component will transform the receipt content made available in the component using Exclusive XML Canonicalization.

If False the component will not alter the received receipt. The value of Content will not itself be a well formed XML document.

UseTransformedXMLAttachment: Whether to send the canonicalized XML.

By default, when an XML document is specified in the EDIData, it will be canonicalized (c14n) in order to calculate the hash value. When the XML attachment is transmitted, this canonicalized data is used by default (True). When set to False, the component will transmit the original data instead.

HTTP Config Settings

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

When AllowHTTPCompression is True, the component 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 component 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 component will accept compressed data. It then will uncompress the data it has received. The component will handle data compressed by both gzip and deflate compression algorithms.

When True, the component 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 component will automatically use HTTP/1.1 if the server does not support HTTP/2. If set to False, the component raises an exception 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 component can be extended with other security schemes in addition to the authorization schemes already implemented by the component.

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 component.

If set to True, the URL passed to the component 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 component 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 component raises an exception.

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 component raises an exception instead.

Following are the valid options:

0 - Never
1 - Always
2 - Same Scheme

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

The default value is False. If set to True, the component 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 component.

This property specifies the HTTP version used by the component. 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 component 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 component 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 component 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 ('#13#10') .

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 component beyond what is provided.

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

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

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

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

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

This configuration setting is provided for use by components 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 components 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 components 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 component.

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 component.

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 component 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 component 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.

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

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

When True (default), the component 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

CloseStreamAfterTransfer: If true, the component will close the upload or download stream after the transfer.

This configuration setting determines whether the input or output stream is closed after the transfer completes. When set to True (default), all streams will be closed after a transfer is completed. To keep streams open after the transfer of data, set this to False. The default value is True.

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

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

This configuration setting is provided for use by components 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 components 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 component raises an exception.

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

FirewallType: Determines the type of firewall to connect through.

Possible values are as follows:


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

Note: This setting is provided for use by components 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 component raises an exception.

Note: This setting is provided for use by components 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 component returns control immediately, the system could hold system resources until all pending data are sent (even after your application closes).

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

LingerTime: Time in seconds to have the connection linger.

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

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

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

In multihomed hosts (machines with more than one IP interface), setting LocalHost to the value of an interface will make the component initiate connections (or accept in the case of server components) only through that interface.

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

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

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

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

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

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

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

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

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

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

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

MaxTransferRate: The transfer rate limit in bytes per second.

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

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

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

www.google.com;www.nsoftware.com

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

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

Note: This value is not applicable in Java.

TcpNoDelay: Whether or not to delay when sending packets.

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

By default, this configuration setting is set to False.

UseIPv6: Whether to use IPv6.

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


0	IPv4 only
1	IPv6 only
2	IPv6 with IPv4 fallback

SSL Config Settings

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

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

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

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

OpenSSLCADir: The path to a directory containing CA certificates.

This functionality is available only when the provider is OpenSSL.

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

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

This functionality is available only when the provider is OpenSSL.

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

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

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

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

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

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

This functionality is available only when the provider is OpenSSL.

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

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

This functionality is available only when the provider is OpenSSL.

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

ReuseSSLSession: Determines if the SSL session is reused.

If set to True, the component 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 component is the same.

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

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

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

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

This configuration setting specifies whether the component will check the Certificate Revocation List (CRL) specified by the server certificate. If set to 1 or 2, the component will first obtain the list of CRL URLs from the server certificate's CRL distribution points extension. The component 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 component raises an exception.

When set to 0 (default), the CRL check will not be performed by the component. When set to 1, it will attempt to perform the CRL check, but it 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 supported only in the Java, C#, and C++ editions. In the C++ edition, it is supported only on Windows operating systems.

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

This configuration setting specifies whether the component will use OCSP to check the validity of the server certificate. If set to 1 or 2, the component will first obtain the Online Certificate Status Protocol (OCSP) URL from the server certificate's OCSP extension. The component 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 component raises an exception.

When set to 0 (default), the component will not perform an OCSP check. When set to 1, it will attempt to perform the OCSP check, but it 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 supported only in the Java, C#, and C++ editions. In the C++ edition, it is supported only on Windows operating systems.

SSLCipherStrength: The minimum cipher strength used for bulk encryption.

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

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

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

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

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

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

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

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

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

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

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

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

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

Multiple cipher suites are separated by semicolons.

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

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

TLS_AES_256_GCM_SHA384
TLS_CHACHA20_POLY1305_SHA256
TLS_AES_128_GCM_SHA256

SSLEnabledCipherSuites is used together with SSLCipherStrength.

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

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

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


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

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

SSLEnabledProtocols: Transport Layer Security (TLS) 1.3 Notes:

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

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

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

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

SSLEnabledProtocols: SSL2 and SSL3 Notes:

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

SSLEnableRenegotiation: Whether the renegotiation_info SSL extension is supported.

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

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

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

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

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

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

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

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

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

SSLNegotiatedCipher: Returns the negotiated cipher suite.

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

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

SSLNegotiatedCipherStrength: Returns the negotiated cipher suite strength.

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

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

SSLNegotiatedCipherSuite: Returns the negotiated cipher suite.

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

SSLNegotiatedKeyExchange: Returns the negotiated key exchange algorithm.

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

SSLNegotiatedKeyExchangeStrength: Returns the negotiated key exchange algorithm strength.

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

SSLNegotiatedVersion: Returns the negotiated protocol version.

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

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

SSLSecurityFlags: Flags that control certificate verification.

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


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

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

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

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

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

-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw
... Intermediate Cert...
eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w
F0I1XhM+pKj7FjDr+XNj
-----END CERTIFICATE-----
\r \n
-----BEGIN CERTIFICATE-----

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

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

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

When specified the component will verify that the server certificate signature algorithm is among the values specified in this configuration setting. If the server certificate signature algorithm is unsupported, the component raises an exception.

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

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

TLS12SupportedGroups: The supported groups for ECC.

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

The default value is ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1.

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

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

TLS13KeyShareGroups: The groups for which to pregenerate key shares.

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

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

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

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

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

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

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

TLS13SignatureAlgorithms: The allowed certificate signature algorithms.

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

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

Socket Config Settings

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

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

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

FirewallData: Used to send extra data to the firewall.

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

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

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

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

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

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

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

Base Config Settings

BuildInfo: Information about the product's build.

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

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

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

LicenseInfo: Information about the current license.

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

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

MaskSensitiveData: Whether sensitive data is masked in log messages.

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

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

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

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

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

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

Note: This setting is applicable only on Windows.

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

UseInternalSecurityAPI: Whether or not to use the system security libraries or an internal implementation.

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

Setting this configuration setting to True tells the component to use the internal implementation instead of using the system security libraries.

This setting is set to False by default on all platforms.
