AS4Client Class

Properties   Methods   Events   Config Settings   Errors  

The AS4Client class connects to a server to send or receive files.

Syntax

ipworksedi.As4client

Remarks

The AS4Client component may be used to send or receive files from a server. The component will connect to a server and either send files (push), or request files to download (pull).

Sending Files

SendFiles sends the files specified by EDIData to URL.

Before calling this method set AgreementRef to the agreement identifier used by both parties. Set AS4From and AS4To. Set EDIData specifies the file(s) to be sent. To encrypt the data set RecipientCerts. To sign the data set SigningCert. The SignerCert property should be set to verify the signed receipt.

When this method is called the file(s) will be sent and any returned receipts will be verified.

To indicate a synchronous receipt is expected set ReceiptReplyMode to rrmSync. The following properties are applicable when calling this method with an agreement specifying a synchronous receipt (a receipt provided in the response):

• AgreementRef
• AS4From
• AS4To
• EDIData
• URL
• RecipientCerts (required to encrypt)
• SignerCert (required to verify signed receipts)
• SigningCert (required to sign files)
• ConversationId (optional)
• EncryptionAlgorithm (optional)
• LogDirectory (optional)
• MessageId (optional)
• MessageProperties (optional)
• Profile (optional)
• ReceiptReplyMode
• Service (optional)
• ServiceType (optional)
• SignatureAlgorithm (optional)

SendFiles Example (synchronous receipt): client.Profile = As4clientProfiles.ebpfENTSOG; //Specify the agreement and party information client.AgreementRef = "http://agreements.company.com/sign_and_encrypt"; client.AS4From.Role = "Sender"; client.AS4From.Id = "org:b2b:example:company:A"; client.AS4To.Role = "Receiver"; client.AS4To.Id = "org:b2b:example:company:B"; //Configure the component to expect a synchronous receipt. client.ReceiptReplyMode = As4clientReceiptReplyModes.rrmSync; //Company A's private certificate. Used to sign the outgoing message and files. client.SigningCert = new Certificate(CertStoreTypes.cstPFXFile, "C:\\files\\CompanyA.pfx", "password", "*"); //Company B's public certificate. Used to encrypt the outgoing file. client.RecipientCerts.Add(new Certificate("C:\\files\\as4\\CompanyB.cer")); //Company B's public certificate. Used to verify the signed receipt. client.SignerCert = new Certificate("C:\\files\\as4\\CompanyB.cer"); client.URL = "http://www.company.com:9090/msh"; EBData data = new EBData(); data.EDIType = "application/edi-x12"; data.Filename = "C:\\files\\myfile.x12"; data.Name = "myfile.x12"; client.EDIData.Add(data); //Send file(s) and verify the receipt. client.SendFiles();

The class also supports asynchronous receipts. In this configuration a file is sent from the class to another party, but the receipt is not returned in the response. Instead the other party sends the receipt at a later time. The AS4Server class may be used inside a web page to receive the asynchronous receipt. After receiving the receipt either AS4Server or AS4Client may be used to verify the receipt.

Details about the original message must be stored so that the receipt can be correlated with the message and properly verified. The easiest way to do this is to set AsyncReceiptInfoDir before calling SendFiles. The class will automatically store the required information.

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

To indicate an asynchronous receipt is expected set ReceiptReplyMode to rrmAsync. The following properties are applicable when calling this method with an agreement specifying a synchronous receipt (a receipt provided in the response):

• AgreementRef
• AS4From
• AS4To
• AsyncReceiptInfoDir
• EDIData
• URL
• RecipientCerts (required to encrypt)
• SignerCert (required to verify signed receipts)
• SigningCert (required to sign files)
• ConversationId (optional)
• EncryptionAlgorithm (optional)
• LogDirectory (optional)
• MessageId (optional)
• MessageProperties (optional)
• OriginalSOAPMessage (optional)
• OriginalSOAPMessageId (optional)
• Profile (optional)
• ReceiptReplyMode
• Service (optional)
• ServiceType (optional)
• SignatureAlgorithm (optional)

SendFiles Example (asynchronous receipt): client.Profile = As4clientProfiles.ebpfENTSOG; //Specify the agreement and party information client.AgreementRef = "http://agreements.company.com/sign_and_encrypt_async"; client.AS4From.Role = "Sender"; client.AS4From.Id = "org:b2b:example:company:A"; client.AS4To.Role = "Receiver"; client.AS4To.Id = "org:b2b:example:company:B"; //Configure the component to expect a synchronous receipt. client.ReceiptReplyMode = As4clientReceiptReplyModes.rrmAsync; client.AsyncReceiptInfoDir = "C:\\async_info"; //Company A's private certificate. Used to sign the outgoing message and files. client.SigningCert = new Certificate(CertStoreTypes.cstPFXFile, "C:\\files\\CompanyA.pfx", "password", "*"); //Company B's public certificate. Used to encrypt the outgoing files. client.RecipientCerts.Add(new Certificate("C:\\files\\as4\\CompanyB.cer")); //Company B's public certificate. Used to verify the signed receipt. client.SignerCert = new Certificate("C:\\files\\as4\\CompanyB.cer"); client.URL = "http://www.company.com:9090/msh"; EBData data = new EBData(); data.EDIType = "application/edi-x12"; data.Filename = "C:\\files\\myfile.x12"; data.Name = "myfile.x12"; client.EDIData.Add(data); //Send file(s). client.SendFiles();

At this point the file(s) have been sent, but a receipt has not yet been received. AS4Server can be used within a web site to listen for the receipt. //**** Inside a web site **** As4server server = new As4server; server.ReadRequest(); if (!String.IsNullOrEmpty(server.IncomingReceipt.Content)) { server.AsyncReceiptInfoDir = "C:\\async_info"; server.VerifyReceipt(); //The receipt is now verified }

Receiving Files

ReceiveFiles establishes a connection to the server specified by URL and receives files.

The MPC specifies the Message Partition Channel from which messages will be received. The server will reply with files from this channel. If IncomingDirectory is set before calling this method the files will be written to the specified folder, otherwise inspect EDIData to obtain the received file data. The following properties are applicable when calling this method:

• SigningCert (required to sign the request)
• Certificate (required for decryption)
• SignerCert (required for signature verification)
• URL
• IncomingDirectory (optional)
• LogDirectory
• MPC
• TokenUser
• TokenPassword
• TokenPasswordType

• AS4From
• AS4To
• AgreementRef
• ConversationId
• Service
• ServiceAction
• ServiceType
• MessageId
• Receipt

To bundle the receipt with a subsequent ReceiveFiles call the Receipt property must hold the receipt. If the same instance of the class is being used this is already true since Receipt is populated automatically after receiving the file. To use another instance of the class for multiple calls to ReceiveFiles be sure to save the Receipt's Content and RefToMessageId values for later use.

ReceiveFiles Example: client.Profile = As4clientProfiles.ebpfENTSOG; //Company A's private certificate. Used for signing the request. client.SigningCert = new Certificate(CertStoreTypes.cstPFXFile, "C:\\files\\as4\\CompanyA.pfx", "password", "*"); //Company A's private certificate. Used for decrypting the file. client.Certificate = new Certificate(CertStoreTypes.cstPFXFile, "C:\\files\\as4\\CompanyA.pfx", "password", "*"); //Company B's public certificate. Used for signature verification. client.SignerCert = new Certificate("C:\\files\\as4\\CompanyB.cer"); client.URL = "http://www.company.com:9090/msh"; //Message Channel id client.MPC = "mpc_a"; client.IncomingDirectory = "C:\\incoming_dir"; client.ReceiveFiles(); //Inspect client.AgreementRef and other properties for information about the received files Console.WriteLine(client.AgreementRef); Console.WriteLine(client.AS4From.Id); Console.WriteLine(client.AS4To.Id); Console.WriteLine(client.ConversationId); //Save the receipt for later use string receiptContent = client.Receipt.Content; string receiptRefId = client.Receipt.RefToMessageId;

At this stage the receipt data is saved. Later when making another call to ReceiveFiles and populate the Receipt property with this receipt data. When ReceiveFiles is called again, the receipt for the previous message will be included with the request. client.Receipt = new EBReceipt(receiptRefId, receiptContent); client.ReceiveFiles(); //This will now include the bundled receipt

Sending Asynchronous Receipts

SendReceipt sends an asynchronous receipt to the URL.

This method is typically used in conjunction with AS4Server to send an asynchronous receipt after receiving a message. The receipt will be created at the time of the incoming request, then saved for later use. When the receipt is to be sent populate Receipt and call this method.

//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();

Config Settings

The following is a list of config settings for the class with short descriptions. Click on the links for further details.

AgreementRef Property (AS4Client Class)

The agreement reference.

Syntax

public String getAgreementRef();


public void setAgreementRef(String 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 (AS4Client Class)

Defines information about the originating party.

Syntax

public EBPartyInfo getAS4From();


public void setAS4From(EBPartyInfo AS4From);

Remarks

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

AS4To Property (AS4Client Class)

Defines information about the responding party.

Syntax

public EBPartyInfo getAS4To();


public void setAS4To(EBPartyInfo AS4To);

Remarks

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

AsyncReceiptInfoDir Property (AS4Client Class)

A directory to hold information used for asynchronous receipt verification.

Syntax

public String getAsyncReceiptInfoDir();


public void setAsyncReceiptInfoDir(String 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 (AS4Client Class)

The certificate with private key used for decryption.

Syntax

public Certificate getCertificate();


public void setCertificate(Certificate certificate);

Default Value

0

Remarks

This setting specifies the compression format to be applied to the parts specified by EDIData. When Profile is set to Standard the default value is 0 (ebcfNone). When Profile is set to ENTSOG or eDelivery the default value is 1 (ebcfGZIP).

Possible values are:

• 0 (ebcfNone - default for Standard)
• 1 (ebcfGZIP - default for ENTSOG and eDelivery)

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.

ConversationId Property (AS4Client Class)

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"

Cookies Property (AS4Client Class)

This property includes a collection of cookies.

Syntax

public HTTPCookieList getCookies();


public void setCookies(HTTPCookieList cookies);

Remarks

This property contains a collection of cookies. To add cookies to outgoing HTTP requests, add cookies (of type HTTPCookie) to this collection.

To see cookies that are set by the server, use the SetCookie event, which displays the cookies and their properties as set by the server. Those cookies also are added to Cookies.

EncryptionAlgorithm Property (AS4Client Class)

The algorithm used to encrypt the EDI data.

Syntax

public String getEncryptionAlgorithm();


public void setEncryptionAlgorithm(String encryptionAlgorithm);

Default Value

"AES128GCM"

Remarks

If RecipientCerts contains a valid certificate, the data will be encrypted using this certificate and the algorithm specified in EncryptionAlgorithm. If EncryptionAlgorithm is set to the empty string, the data will not be encrypted.

The class supports "3DES", or industry-standard 168-bit Triple-DES encryption.

The class supports "AES" encryption with a default keysize of 128 bits. You may also set "AESCBC192" or "AESCBC256" for 192- and 256-bit keysizes.

The directory to which incoming files are saved.

Syntax

public String getIncomingDirectory();


public void setIncomingDirectory(String 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.

LocalHost Property (AS4Client Class)

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

Syntax

public String getLocalHost();


public void setLocalHost(String localHost);

Default Value

""

Remarks

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

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

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

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

LogDirectory Property (AS4Client Class)

The path to a directory for logging.

Syntax

public String getLogDirectory();


public void setLogDirectory(String 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 class will log the complete text of the outgoing request and the incoming response.

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

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 class will attempt to create the directory. The following macros are supported:

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

If logs cannot be written an exception will be thrown.

LogFile Property (AS4Client Class)

The log file written.

Syntax

public String getLogFile();

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

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 class will attempt to create the directory. The following macros are supported:

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

If logs cannot be written an exception will be thrown.

This property is read-only.

MessageId Property (AS4Client Class)

The unique Id of the message.

Syntax

public String getMessageId();


public void setMessageId(String messageId);

Default Value

""

Remarks

This property defines the unique Id of the message. When sending files the class 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 (AS4Client Class)

A collection of message properties.

Syntax

public EBPropertyList getMessageProperties();


public void setMessageProperties(EBPropertyList 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 field 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""

OriginalSOAPMessage Property (AS4Client Class)

The original SOAP message used to verify the receipt.

Syntax

public String getOriginalSOAPMessage();


public void setOriginalSOAPMessage(String 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 (AS4Client Class)

The original SOAP message Id used to verify the receipt.

Syntax

public String getOriginalSOAPMessageId();


public void setOriginalSOAPMessageId(String originalSOAPMessageId);

Default Value

Remarks

This property holds the receipt of a message.

Sending

When sending files if a synchronous receipt is returned in the response it is verified and this property is populated.

Receiving

When receiving files this property is populated with the receipt to send after a file is received. If this property is populated the receipt will be sent in the next request made by calling ReceiveFiles.

If the receipt is not to be bundled with a subsequent call to ReceiveFiles the SendReceipt method may be used to directly send a receipt to the other party.

ReceiptReplyMode Property (AS4Client Class)

The expected receipt reply mode.

Syntax

public int getReceiptReplyMode();

Specifies the RefToMessageId in the message.

Syntax

public String getRefToMessageId();


public void setRefToMessageId(String refToMessageId);

Default Value

""

Remarks

This property specifies the RefToMessageId value in the message being sent.

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.

Service Property (AS4Client Class)

SigningCert Property (AS4Client Class)

The certificate with private key used to sign messages and files.

Syntax

public Certificate getSigningCert();


public void setSigningCert(Certificate signingCert);

Remarks

This property specifies a certificate with private key used to sign outgoing messages and files. If this property is specified, the message content will be signed using the algorithm given by SignatureAlgorithm.

Used to sign any outgoing message. This applies to requests made when calling SendFiles and ReceiveFiles.

SSLAcceptServerCert Property (AS4Client Class)

Instructs the class to unconditionally accept the server certificate that matches the supplied certificate.

Syntax

public Certificate getSSLAcceptServerCert();


public void setSSLAcceptServerCert(Certificate SSLAcceptServerCert);

Remarks

If it finds any issues with the certificate presented by the server, the class will normally terminate the connection with an error.

You may override this behavior by supplying a value for SSLAcceptServerCert. If the certificate supplied in SSLAcceptServerCert is the same as the certificate presented by the server, then the server certificate is accepted unconditionally, and the connection will continue normally.

Please note that this functionality is provided only for cases where you otherwise know that you are communicating with the right server. If used improperly, this property may create a security breach. Use it at your own risk.

This property specifies the SSL/TLS implementation to use. In most cases the default value of 0 (Automatic) is recommended and should not be changed. When set to 0 (Automatic) the class will select whether to use the platform implementation or the internal implementation depending on the operating system as well as the TLS version being used.

Possible values are:

In most cases using the default value (Automatic) is recommended. The class will select a provider depending on the current platform.

When Automatic is selected the platform implementation is used by default. When TLS 1.3 is enabled via SSLEnabledProtocols the internal implementation is used.

SSLServerCert Property (AS4Client Class)

The server certificate for the last established connection.

Syntax

public Certificate getSSLServerCert();

Remarks

SSLServerCert contains the server certificate for the last established connection.

SSLServerCert is reset every time a new connection is attempted.

This property is read-only.

Timeout Property (AS4Client Class)

A timeout for the class.

Syntax

public int getTimeout();


public void setTimeout(int timeout);

Default Value

60

Remarks

If the Timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.

If Timeout is set to a positive value, the class will wait for the operation to complete before returning control.

The class will use DoEvents to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not "freeze" and remains responsive.

If Timeout expires, and the operation is not yet complete, the class throws an exception.

Please note that by default, all timeouts are inactivity timeouts, i.e. the timeout period is extended by Timeout seconds when any amount of data is successfully sent or received.

The default value for the Timeout property is 60 seconds.

TokenPassword Property (AS4Client Class)

The password used in UsernameToken authentication.

Syntax

public String getTokenPassword();


public void setTokenPassword(String tokenPassword);

Default Value

""

Remarks

This property specifies the password used in UsernameToken authentication.

UsernameToken Authentication Notes

If TokenUser and TokenPassword are specified the class will include UsernameToken authentication when ReceiveFiles is called. This functionality is only applicable when calling ReceiveFiles.

TokenPassword should normally be set to the plaintext password that both the client and server know. The class will automatically use SHA-1 to create a hash of the password when TokenPasswordType is set to tptDigest (default). The hashed password is sent in the request, along with a creation date and nonce. The server will validate these values when receiving the request.

client.TokenUser = "User"; client.TokenPassword = "MyPassword"; client.TokenPasswordType = As4clientTokenPasswordTypes.tptDigest; client.ReceiveFiles();

A creation date element is always sent in the request. A nonce is sent by default but can be disabled by setting UseNonce to False.

If TokenPasswordType is set to tptText the class will transmit value provided in TokenPassword exactly as it is provided. The value will not be hashed. This may be useful in cases where an alternative credential mechanism is used between the client and server.

TokenPasswordType Property (AS4Client Class)

The password type used in UsernameToken authentication.

Syntax

public int getTokenPasswordType();


public void setTokenPasswordType(int tokenPasswordType);


Enumerated values:
  public final static int tptDigest = 0;
  public final static int tptText = 1;

Default Value

0

Remarks

The type of password to send in the request. Possible values are:

UsernameToken Authentication Notes

If TokenUser and TokenPassword are specified the class will include UsernameToken authentication when ReceiveFiles is called. This functionality is only applicable when calling ReceiveFiles.

TokenPassword should normally be set to the plaintext password that both the client and server know. The class will automatically use SHA-1 to create a hash of the password when TokenPasswordType is set to tptDigest (default). The hashed password is sent in the request, along with a creation date and nonce. The server will validate these values when receiving the request.

client.TokenUser = "User"; client.TokenPassword = "MyPassword"; client.TokenPasswordType = As4clientTokenPasswordTypes.tptDigest; client.ReceiveFiles();

A creation date element is always sent in the request. A nonce is sent by default but can be disabled by setting UseNonce to False.

If TokenPasswordType is set to tptText the class will transmit value provided in TokenPassword exactly as it is provided. The value will not be hashed. This may be useful in cases where an alternative credential mechanism is used between the client and server.

TokenUser Property (AS4Client Class)

The username used in UsernameToken authentication.

Syntax

public String getTokenUser();


public void setTokenUser(String tokenUser);

Default Value

""

Remarks

This property specifies the username to be sent for UsernameToken authentication.

UsernameToken Authentication Notes

If TokenUser and TokenPassword are specified the class will include UsernameToken authentication when ReceiveFiles is called. This functionality is only applicable when calling ReceiveFiles.

TokenPassword should normally be set to the plaintext password that both the client and server know. The class will automatically use SHA-1 to create a hash of the password when TokenPasswordType is set to tptDigest (default). The hashed password is sent in the request, along with a creation date and nonce. The server will validate these values when receiving the request.

client.TokenUser = "User"; client.TokenPassword = "MyPassword"; client.TokenPasswordType = As4clientTokenPasswordTypes.tptDigest; client.ReceiveFiles();

A creation date element is always sent in the request. A nonce is sent by default but can be disabled by setting UseNonce to False.

If TokenPasswordType is set to tptText the class will transmit value provided in TokenPassword exactly as it is provided. The value will not be hashed. This may be useful in cases where an alternative credential mechanism is used between the client and server.

URL Property (AS4Client Class)

The URL to which the request is made.

Syntax

public String getURL();


public void setURL(String URL);

Default Value

""

Remarks

This property specifies the URL to which the request is made. SSL will be used if and only if the URL scheme is "https".

Config Method (As4client Class)

Sets or retrieves a configuration setting.

Syntax

public String config(String 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 (As4client Class)

Processes events from the internal message queue.

Syntax

public void doEvents();

Remarks

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

Interrupt Method (As4client Class)

Interrupt the current method.

Syntax

public void interrupt();

Remarks

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

ReceiveFiles Method (As4client Class)

Connects to a server to receive files.

Syntax

public void receiveFiles();

Remarks

ReceiveFiles establishes a connection to the server specified by URL and receives files.

The MPC specifies the Message Partition Channel from which messages will be received. The server will reply with files from this channel. If IncomingDirectory is set before calling this method the files will be written to the specified folder, otherwise inspect EDIData to obtain the received file data. The following properties are applicable when calling this method:

• SigningCert (required to sign the request)
• Certificate (required for decryption)
• SignerCert (required for signature verification)
• URL
• IncomingDirectory (optional)
• LogDirectory
• MPC
• TokenUser
• TokenPassword
• TokenPasswordType

• AS4From
• AS4To
• AgreementRef
• ConversationId
• Service
• ServiceAction
• ServiceType
• MessageId
• Receipt

To bundle the receipt with a subsequent ReceiveFiles call the Receipt property must hold the receipt. If the same instance of the class is being used this is already true since Receipt is populated automatically after receiving the file. To use another instance of the class for multiple calls to ReceiveFiles be sure to save the Receipt's Content and RefToMessageId values for later use.

ReceiveFiles Example: client.Profile = As4clientProfiles.ebpfENTSOG; //Company A's private certificate. Used for signing the request. client.SigningCert = new Certificate(CertStoreTypes.cstPFXFile, "C:\\files\\as4\\CompanyA.pfx", "password", "*"); //Company A's private certificate. Used for decrypting the file. client.Certificate = new Certificate(CertStoreTypes.cstPFXFile, "C:\\files\\as4\\CompanyA.pfx", "password", "*"); //Company B's public certificate. Used for signature verification. client.SignerCert = new Certificate("C:\\files\\as4\\CompanyB.cer"); client.URL = "http://www.company.com:9090/msh"; //Message Channel id client.MPC = "mpc_a"; client.IncomingDirectory = "C:\\incoming_dir"; client.ReceiveFiles(); //Inspect client.AgreementRef and other properties for information about the received files Console.WriteLine(client.AgreementRef); Console.WriteLine(client.AS4From.Id); Console.WriteLine(client.AS4To.Id); Console.WriteLine(client.ConversationId); //Save the receipt for later use string receiptContent = client.Receipt.Content; string receiptRefId = client.Receipt.RefToMessageId;

At this stage the receipt data is saved. Later when making another call to ReceiveFiles and populate the Receipt property with this receipt data. When ReceiveFiles is called again, the receipt for the previous message will be included with the request. client.Receipt = new EBReceipt(receiptRefId, receiptContent); client.ReceiveFiles(); //This will now include the bundled receipt

Reset Method (As4client Class)

Resets the state of the control.

Syntax

public void reset();

Remarks

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

SendFiles Method (As4client Class)

Sends file(s) to the specified server and verify the receipt (if present).

Syntax

public void sendFiles();

Remarks

SendFiles sends the files specified by EDIData to URL.

Before calling this method set AgreementRef to the agreement identifier used by both parties. Set AS4From and AS4To. Set EDIData specifies the file(s) to be sent. To encrypt the data set RecipientCerts. To sign the data set SigningCert. The SignerCert property should be set to verify the signed receipt.

When this method is called the file(s) will be sent and any returned receipts will be verified.

To indicate a synchronous receipt is expected set ReceiptReplyMode to rrmSync. The following properties are applicable when calling this method with an agreement specifying a synchronous receipt (a receipt provided in the response):

• AgreementRef
• AS4From
• AS4To
• EDIData
• URL
• RecipientCerts (required to encrypt)
• SignerCert (required to verify signed receipts)
• SigningCert (required to sign files)
• ConversationId (optional)
• EncryptionAlgorithm (optional)
• LogDirectory (optional)
• MessageId (optional)
• MessageProperties (optional)
• Profile (optional)
• ReceiptReplyMode
• Service (optional)
• ServiceType (optional)
• SignatureAlgorithm (optional)

SendFiles Example (synchronous receipt): client.Profile = As4clientProfiles.ebpfENTSOG; //Specify the agreement and party information client.AgreementRef = "http://agreements.company.com/sign_and_encrypt"; client.AS4From.Role = "Sender"; client.AS4From.Id = "org:b2b:example:company:A"; client.AS4To.Role = "Receiver"; client.AS4To.Id = "org:b2b:example:company:B"; //Configure the component to expect a synchronous receipt. client.ReceiptReplyMode = As4clientReceiptReplyModes.rrmSync; //Company A's private certificate. Used to sign the outgoing message and files. client.SigningCert = new Certificate(CertStoreTypes.cstPFXFile, "C:\\files\\CompanyA.pfx", "password", "*"); //Company B's public certificate. Used to encrypt the outgoing file. client.RecipientCerts.Add(new Certificate("C:\\files\\as4\\CompanyB.cer")); //Company B's public certificate. Used to verify the signed receipt. client.SignerCert = new Certificate("C:\\files\\as4\\CompanyB.cer"); client.URL = "http://www.company.com:9090/msh"; EBData data = new EBData(); data.EDIType = "application/edi-x12"; data.Filename = "C:\\files\\myfile.x12"; data.Name = "myfile.x12"; client.EDIData.Add(data); //Send file(s) and verify the receipt. client.SendFiles();

The class also supports asynchronous receipts. In this configuration a file is sent from the class to another party, but the receipt is not returned in the response. Instead the other party sends the receipt at a later time. The AS4Server class may be used inside a web page to receive the asynchronous receipt. After receiving the receipt either AS4Server or AS4Client may be used to verify the receipt.

Details about the original message must be stored so that the receipt can be correlated with the message and properly verified. The easiest way to do this is to set AsyncReceiptInfoDir before calling SendFiles. The class will automatically store the required information.

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

To indicate an asynchronous receipt is expected set ReceiptReplyMode to rrmAsync. The following properties are applicable when calling this method with an agreement specifying a synchronous receipt (a receipt provided in the response):

• AgreementRef
• AS4From
• AS4To
• AsyncReceiptInfoDir
• EDIData
• URL
• RecipientCerts (required to encrypt)
• SignerCert (required to verify signed receipts)
• SigningCert (required to sign files)
• ConversationId (optional)
• EncryptionAlgorithm (optional)
• LogDirectory (optional)
• MessageId (optional)
• MessageProperties (optional)
• OriginalSOAPMessage (optional)
• OriginalSOAPMessageId (optional)
• Profile (optional)
• ReceiptReplyMode
• Service (optional)
• ServiceType (optional)
• SignatureAlgorithm (optional)

SendFiles Example (asynchronous receipt): client.Profile = As4clientProfiles.ebpfENTSOG; //Specify the agreement and party information client.AgreementRef = "http://agreements.company.com/sign_and_encrypt_async"; client.AS4From.Role = "Sender"; client.AS4From.Id = "org:b2b:example:company:A"; client.AS4To.Role = "Receiver"; client.AS4To.Id = "org:b2b:example:company:B"; //Configure the component to expect a synchronous receipt. client.ReceiptReplyMode = As4clientReceiptReplyModes.rrmAsync; client.AsyncReceiptInfoDir = "C:\\async_info"; //Company A's private certificate. Used to sign the outgoing message and files. client.SigningCert = new Certificate(CertStoreTypes.cstPFXFile, "C:\\files\\CompanyA.pfx", "password", "*"); //Company B's public certificate. Used to encrypt the outgoing files. client.RecipientCerts.Add(new Certificate("C:\\files\\as4\\CompanyB.cer")); //Company B's public certificate. Used to verify the signed receipt. client.SignerCert = new Certificate("C:\\files\\as4\\CompanyB.cer"); client.URL = "http://www.company.com:9090/msh"; EBData data = new EBData(); data.EDIType = "application/edi-x12"; data.Filename = "C:\\files\\myfile.x12"; data.Name = "myfile.x12"; client.EDIData.Add(data); //Send file(s). client.SendFiles();

At this point the file(s) have been sent, but a receipt has not yet been received. AS4Server can be used within a web site to listen for the receipt. //**** Inside a web site **** As4server server = new As4server; server.ReadRequest(); if (!String.IsNullOrEmpty(server.IncomingReceipt.Content)) { server.AsyncReceiptInfoDir = "C:\\async_info"; server.VerifyReceipt(); //The receipt is now verified }

SendReceipt Method (As4client Class)

Sends an asynchronous receipt.

Syntax

public void sendReceipt();

Remarks

SendReceipt sends an asynchronous receipt to the URL.

This method is typically used in conjunction with AS4Server to send an asynchronous receipt after receiving a message. The receipt will be created at the time of the incoming request, then saved for later use. When the receipt is to be sent populate Receipt and call this method.

//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();

Connected Event (As4client Class)

This event is fired immediately after a connection completes (or fails).

Syntax

public class DefaultAs4clientEventListener implements As4clientEventListener {
  ...
  public void connected(As4clientConnectedEvent e) {}
  ...
}

public class As4clientConnectedEvent {
  public int statusCode;
  public String description;
}

Remarks

If the connection is made normally, StatusCode is 0 and Description is "OK".

If the connection fails, StatusCode has the error code returned by the Transmission Control Protocol (TCP)/IP stack. Description contains a description of this code. The value of StatusCode is equal to the value of the error.

Please refer to the Error Codes section for more information.

Disconnected Event (As4client Class)

This event is fired when a connection is closed.

Syntax

public class DefaultAs4clientEventListener implements As4clientEventListener {
  ...
  public void disconnected(As4clientDisconnectedEvent e) {}
  ...
}

public class As4clientDisconnectedEvent {
  public int statusCode;
  public String description;
}

Remarks

If the connection is broken normally, StatusCode is 0 and Description is "OK".

If the connection is broken for any other reason, StatusCode has the error code returned by the Transmission Control Protocol (TCP/IP) subsystem. Description contains a description of this code. The value of StatusCode is equal to the value of the TCP/IP error.

Please refer to the Error Codes section for more information.

EndTransfer Event (As4client Class)

This event is fired when a document finishes transferring.

Syntax

public class DefaultAs4clientEventListener implements As4clientEventListener {
  ...
  public void endTransfer(As4clientEndTransferEvent e) {}
  ...
}

public class As4clientEndTransferEvent {
  public int direction;
}

Remarks

The EndTransfer event is fired first when the client finishes sending data to the server (in a POST or PUT request) and then when the document text finishes transferring from the server to the local host.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

Error Event (As4client Class)

Information about errors during data delivery.

Syntax

public class DefaultAs4clientEventListener implements As4clientEventListener {
  ...
  public void error(As4clientErrorEvent e) {}

  public int errorCode;
  public String description;
}

Remarks

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

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

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

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

Header Event (As4client Class)

This event is fired every time a header line comes in.

Syntax

public class DefaultAs4clientEventListener implements As4clientEventListener {
  ...
  public void header(As4clientHeaderEvent e) {}
  ...
}

public class As4clientHeaderEvent {
  public String field;
  public String value;
}

Remarks

The Field parameter contains the name of the HTTP header (which is the same as it is delivered). The Value parameter contains the header contents.

If the header line being retrieved is a continuation header line, then the Field parameter contains "" (empty string).

Log Event (As4client Class)

Fired with log information while processing a message.

Syntax

public class DefaultAs4clientEventListener implements As4clientEventListener {
  ...
  public void log(As4clientLogEvent e) {}
  ...
}

public class As4clientLogEvent {
  public String logType;
  public String logMessage;
}

Remarks

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

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

The LogMessage event parameter holds the raw log data.

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

RecipientInfo Event (As4client Class)

Fired for each recipient certificate of the encrypted message.

Syntax

public class DefaultAs4clientEventListener implements As4clientEventListener {
  ...
  public void recipientInfo(As4clientRecipientInfoEvent e) {}
  ...
}

public class As4clientRecipientInfoEvent {
  public String issuer;
  public String serialNumber;
  public String subjectKeyIdentifier;
  public String encryptionAlgorithm;
}

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"

SetCookie Event (As4client Class)

This event is fired for every cookie set by the server.

Syntax

public class DefaultAs4clientEventListener implements As4clientEventListener {
  ...
  public void setCookie(As4clientSetCookieEvent e) {}
  ...
}

public class As4clientSetCookieEvent {
  public String name;
  public String value;
  public String expires;
  public String domain;
  public String path;
  public boolean secure;
}

Remarks

The SetCookie event is fired for every Set-Cookie: header received from the HTTP server.

The Name parameter contains the name of the cookie, with the corresponding value supplied in the Value parameter.

The Expires parameter contains an expiration time for the cookie (if provided by the server). The time format used is "Weekday, DD-Mon-YY HH:MM:SS GMT". If the server does not provide an expiration time, the Expires parameter will be an empty string. In this case, the convention is to drop the cookie at the end of the session.

The Domain parameter contains a domain name to limit the cookie to (if provided by the server). If the server does not provide a domain name, the Domain parameter will be an empty string. The convention in this case is to use the server specified in the URL (URLServer) as the cookie domain.

The Path parameter contains a path name to limit the cookie to (if provided by the server). If the server does not provide a cookie path, the Path parameter will be an empty string. The convention in this case is to use the path specified in the URL (URLPath) as the cookie path.

The Secure parameter specifies whether the cookie is secure. If the value of this parameter is True, the cookie value must be submitted only through a secure (HTTPS) connection.

SignerCertInfo Event (As4client Class)

This event is fired during verification of the signed message.

Syntax

public class DefaultAs4clientEventListener implements As4clientEventListener {
  ...
  public void signerCertInfo(As4clientSignerCertInfoEvent e) {}
  ...
}

public class As4clientSignerCertInfoEvent {
  public String issuer;
  public String serialNumber;
  public String subjectKeyIdentifier;
  public byte[] certEncoded;
}

Remarks

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

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

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

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

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

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

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

SSLServerAuthentication Event (As4client Class)

Fired after the server presents its certificate to the client.

Syntax

public class DefaultAs4clientEventListener implements As4clientEventListener {
  ...
  public void SSLServerAuthentication(As4clientSSLServerAuthenticationEvent e) {}
  ...
}

public class As4clientSSLServerAuthenticationEvent {
  public byte[] certEncoded;
  public String certSubject;
  public String certIssuer;
  public String status;
  public boolean accept;
}

Remarks

This event is where the client can decide whether to continue with the connection process or not. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether to continue or not.

When Accept is False, Status shows why the verification failed (otherwise, Status contains the string "OK"). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.

SSLStatus Event (As4client Class)

Shows the progress of the secure connection.

Syntax

public class DefaultAs4clientEventListener implements As4clientEventListener {
  ...
  public void SSLStatus(As4clientSSLStatusEvent e) {}
  ...
}

public class As4clientSSLStatusEvent {
  public String message;
}

Remarks

The event is fired for informational and logging purposes only. Used to track the progress of the connection.

StartTransfer Event (As4client Class)

This event is fired when a document starts transferring (after the headers).

Syntax

public class DefaultAs4clientEventListener implements As4clientEventListener {
  ...
  public void startTransfer(As4clientStartTransferEvent e) {}
  ...
}

public class As4clientStartTransferEvent {
  public int direction;
}

Remarks

The StartTransfer event is fired first when the client starts sending data to the server (in a POST or PUT request) and then when the document text starts transferring from the server to the local host.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

TokenAuthentication Event (As4client Class)

Fired when the server makes use of UsernameToken authentication.

Syntax

public class DefaultAs4clientEventListener implements As4clientEventListener {
  ...
  public void tokenAuthentication(As4clientTokenAuthenticationEvent e) {}
  ...
}

public class As4clientTokenAuthenticationEvent {
  public String user;
  public String password;
  public String passwordType;
  public boolean accept;
}

Remarks

This event fires when a server sends a response that includes UsernameToken authentication. This is typically only used by servers when sending a pull response.

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 server by calling SendResponse.

Transfer Event (As4client Class)

This event is fired while a document transfers (delivers document).

Syntax

public class DefaultAs4clientEventListener implements As4clientEventListener {
  ...
  public void transfer(As4clientTransferEvent e) {}
  ...
}

public class As4clientTransferEvent {
  public int direction;
  public long bytesTransferred;
  public int percentDone;
  public byte[] text;
}

Remarks

The Text parameter contains the portion of the document text being received. It is empty if data are being posted to the server.

The BytesTransferred parameter contains the number of bytes transferred in this Direction since the beginning of the document text (excluding HTTP response headers).

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

The PercentDone parameter shows the progress of the transfer in the corresponding direction. If PercentDone can not be calculated the value will be -1.

Note: Events are not re-entrant. Performing time-consuming operations within this event will prevent it from firing again in a timely manner and may affect overall performance.

Certificate Type

This is the digital certificate being used.

Remarks

This type describes the current digital certificate. The certificate may be a public or private key. The fields are used to identify or select certificates.

Fields

Constructors

public Certificate();

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

public Certificate( certificateFile);

Opens CertificateFile and reads out the contents as an X509 public key.

public Certificate( certificateData);

Parses CertificateData as an X509 public key.

public Certificate( certStoreType,  store,  storePassword,  subject);

CertStoreType identifies the type of certificate store to use. See StoreType 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 class will attempt to find the certificate identified by Subject . This can be either a complete or a substring match of the X509 certificate's subject Distinguished Name (DN).

public Certificate( certStoreType,  store,  storePassword,  subject,  configurationString);

CertStoreType identifies the type of certificate store to use. See StoreType for descriptions of the different certificate stores. Store is a file containing the certificate store. StorePassword is the password used to protect the store. ConfigurationString is a newline separated list of name-value pairs that may be used to modify the default behavior. Possible values include "PersistPFXKey", which shows whether or not the PFX key is persisted after performing operations with the private key. This correlates to the PKCS12_NO_PERSIST_KEY CyrptoAPI option. The default value is True (the key is persisted). "Thumbprint" - a MD5, SHA1, or SHA256 thumbprint of the certificate to load. When specified, this value is used to select the certificate in the store. This is applicable to cstUser, cstMachine, cstPublicKeyFile, and cstPFXFile store types. "UseInternalSecurityAPI" shows whether the platform (default) or the internal security API is used when performing certificate-related operations. After the store has been successfully opened, the class will attempt to find the certificate identified by Subject .
