Remarks

The AS4Server class 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 class 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 class 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 . Alternatively the request data may be passed directly to the class 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 IncomingReceiptContent 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 class 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 ReceiptContent and ReceiptRefToMessageId 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 ReceiptContent 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(); }

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

Sending

When sending files to add properties set EDIPropertyCount to specify the number of properties. Then set EDIPropertyIndex to select the property. Set EDIPropertyName and EDIPropertyValue to define the values for the property at EDIPropertyIndex. 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 EDIPropertyCount to obtain the number of properties. Next set EDIPropertyIndex to select a property and query EDIPropertyName and EDIPropertyValue. 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 Method (IPWorksEDI_AS4Server Class)

Sets or retrieves a configuration setting.

Object Oriented Interface

public function doConfig($configurationstring);

Procedural Interface

ipworksedi_as4server_do_config($res, $configurationstring);

Remarks

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

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

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

DoEvents Method (IPWorksEDI_AS4Server Class)

Interrupt Method (IPWorksEDI_AS4Server Class)

Interrupt the current method.

Object Oriented Interface

public function doInterrupt();

Procedural Interface

ipworksedi_as4server_do_interrupt($res);

Remarks

If there is no method in progress, Interrupt simply returns, doing nothing.

ParseRequest Method (IPWorksEDI_AS4Server Class)

Parses and processes the message.

Object Oriented Interface

public function doParseRequest();

Procedural Interface

ipworksedi_as4server_do_parserequest($res);

Remarks

This method processes the message in the request. If the message is encrypted, it will be decrypted. If the message is signed, the signature will be verified. 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

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 ReceiptContent and ReceiptRefToMessageId 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(); }

ReadRequest Method (IPWorksEDI_AS4Server Class)

Reads the AS4 request.

Object Oriented Interface

public function doReadRequest();

Procedural Interface

ipworksedi_as4server_do_readrequest($res);

Remarks

To begin, when a request is received first call ReadRequest. This reads the AS4 request from the . Alternatively the request data may be passed directly to the class 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 IncomingReceiptContent 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 class may then be configured to respond appropriately depending on the operation.

Reset Method (IPWorksEDI_AS4Server Class)

Resets the state of the control.

Object Oriented Interface

public function doReset();

Procedural Interface

ipworksedi_as4server_do_reset($res);

Remarks

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

SendAckResponse Method (IPWorksEDI_AS4Server Class)

Sends an acknowledgement of the request only.

Object Oriented Interface

public function doSendAckResponse();

Procedural Interface

ipworksedi_as4server_do_sendackresponse($res);

Remarks

This method is used to respond to a client who sends a file and the agreement dictates that the receipt be returned asynchronously. In this case no receipt should be returned to the client. This method will send an acknowledgment only (no receipt) to the client to indicate that the request was received and processed.

This method is only applicable when ReceiptReplyMode is set to rrmAsync.

SendResponse Method (IPWorksEDI_AS4Server Class)

This method sends the response over the current HTTP context.

Object Oriented Interface

public function doSendResponse();

Procedural Interface

ipworksedi_as4server_do_sendresponse($res);

Remarks

This method sends the response. This should be called after ParseRequest to deliver the response to the client.

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 ReceiptContent and ReceiptRefToMessageId 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(); }

VerifyReceipt Method (IPWorksEDI_AS4Server Class)

Verifies a received receipt.

Object Oriented Interface

public function doVerifyReceipt();

Procedural Interface

ipworksedi_as4server_do_verifyreceipt($res);

Remarks

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

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 ReceiptContent 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(); }

SerialNumber is the serial number of the encryption certificate.

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

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

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

SignerCertInfo Event (IPWorksEDI_AS4Server Class)

This event is fired during verification of the signed message.

Object Oriented Interface

public function fireSignerCertInfo($param);

Procedural Interface

ipworksedi_as4server_register_callback($res, 4, array($this, 'fireSignerCertInfo'));

Parameter List

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

Remarks

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

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

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

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

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

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

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

TokenAuthentication Event (IPWorksEDI_AS4Server Class)

Fired when the client makes use of UsernameToken authentication.

Object Oriented Interface

public function fireTokenAuthentication($param);

Procedural Interface

ipworksedi_as4server_register_callback($res, 5, array($this, 'fireTokenAuthentication'));

Parameter List

 'user'
 'password'
 'passwordtype'
 'accept'

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 class will hash the provided password value and compare it to the value in the request. If it matched the class will accept the request. If it does not match the class 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.
