The AS4Server control implements an AS4 / ebHandler.

Syntax

AS4Server

Remarks

The AS4Server control 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 control 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 control 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 control 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 control 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(); }

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:

SignerCertSubject Property (AS4Server Control)

The subject of the certificate used for client authentication.

Syntax

as4servercontrol.SignerCertSubject[=string]

Default Value

""

Remarks

The subject of the certificate used for client authentication.

This property must be set after all other certificate properties are set. When this property is set, a search is performed in the current certificate store to locate a certificate with a matching subject.

If a matching certificate is found, the property is set to the full subject of the matching certificate.

If an exact match is not found, the store is searched for subjects containing the value of the property.

If a match is still not found, the property is set to an empty string, and no certificate is selected.

The special value "*" picks a random certificate in the certificate store.

The certificate subject is a comma-separated list of distinguished name fields and values. For instance, "CN=www.server.com, OU=test, C=US, E=support@nsoftware.com". Common fields and their meanings are as follows:

If a field value contains a comma, it must be quoted.

Data Type

Binary String

Config Method (AS4Server Control)

Sets or retrieves a configuration setting.

Syntax

as4servercontrol.Config ConfigurationString

Remarks

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

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

This method processes events from the internal message queue.

Syntax

as4servercontrol.DoEvents 

Remarks

When DoEvents is called, the control processes any available events. If no events are available, it waits for a preset period of time, and then returns.

Interrupt Method (AS4Server Control)

This method interrupts the current method.

Syntax

as4servercontrol.Interrupt 

Remarks

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

ParseRequest Method (AS4Server Control)

Parses and processes the message.

Syntax

as4servercontrol.ParseRequest 

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 (AS4Server Control)

Reads the AS4 request.

Syntax

as4servercontrol.ReadRequest 

Remarks

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 control 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 control may then be configured to respond appropriately depending on the operation.

Reset Method (AS4Server Control)

Resets the state of the control.

Syntax

as4servercontrol.Reset 

Remarks

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

SendAckResponse Method (AS4Server Control)

Sends an acknowledgement of the request only.

Syntax

as4servercontrol.SendAckResponse 

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 (AS4Server Control)

This method sends the response over the current HTTP context.

Syntax

as4servercontrol.SendResponse 

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 (AS4Server Control)

Verifies a received receipt.

Syntax

as4servercontrol.VerifyReceipt 

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(); }

Error Event (AS4Server Control)

Fired when information is available about errors during data delivery.

Syntax

Sub as4servercontrol_Error(ErrorCode As Integer, Description As String)

Remarks

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

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

Log Event (AS4Server Control)

Fired with log information while processing a message.

Syntax

Sub as4servercontrol_Log(LogType As String, LogMessage As String)

Remarks

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

RecipientInfo Event (AS4Server Control)

Fired for each recipient certificate of the encrypted message.

Syntax

Sub as4servercontrol_RecipientInfo(Issuer As String, SerialNumber As String, SubjectKeyIdentifier As String, EncryptionAlgorithm As String)

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"
• "AESCBC192"
• "AESCBC256"
• "AESGCM128" or "AESGCM"
• "AESGCM192"
• "AESGCM256"

SignerCertInfo Event (AS4Server Control)

This event is fired during verification of the signed message.

Syntax

Sub as4servercontrol_SignerCertInfo(Issuer As String, SerialNumber As String, SubjectKeyIdentifier As String, CertEncoded As String)

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 control 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 Control)

Fired when the client makes use of UsernameToken authentication.

Syntax

Sub as4servercontrol_TokenAuthentication(User As String, Password As String, PasswordType As String, Accept As Boolean)

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