The AS1Receiver component is used to process AS1 messages and generate receipts.

Syntax

nsoftware.IPWorksEDI.AS1Receiver

Remarks

The AS1Receiver component allows you to receive AS1 messages as specified in RFC 3335. The component can act as an email client, decrypt and verify incoming messages, generate receipts including Message Disposition Notifications (MDNs), and send them over SMTP/S.

Basic Operation

You should first log in to your mail server by setting MailServer, User, and Password, and invoking Connect. You may then navigate your mail inbox by setting MailMessageNumber, and inspecting properties such as MailMessageFrom, etc. When you find the desired file you may download it by invoking ReadRequest. Alternatively, you may acquire the AS1 data by other means and directly set Request and RequestHeaders.

ReadRequest (or ParseHeaders) will determine information such as From and SendTo, which will allow you to set the appropriate certificates. You may specify your certificate with the Certificate property, and your trading partner's (signing) certificate with the SignerCert property.

Then, invoke ProcessRequest to process the request and generate the MDN receipt as specified in RFC 3335. If the request was processed successfully, EDIData will contain the transmitted EDI data. If a problem occurred, EDIData will not be populated and an exception will be thrown. In either case MDNReceipt will contain the RFC-compliant receipt, which should be returned to the client.

The MDNReceipt may be returned over SMTP/S by invoking SendResponse. In case the server address for incoming mail is different than that for outgoing mail you should use Config to configure this.

To create log files, set LogDirectory prior to invoking ProcessRequest. This will log all incoming and outgoing data, and will also write the received EDI files to disk.

Example AS1Receiver1.User = "myusername" AS1Receiver1.Password = "mypassword" AS1Receiver1.MailServer = "1.2.3.4" AS1Receiver1.Connect() // You may need to search the server for received files at this point AS1Receiver1.MessageNumber = 1; // You may check properties such as MailMessageFrom, etc. AS1Receiver1.ReadRequest() AS1Receiver1.Certificate = new Certificate(CertStoreTypes.cstPFXFile, "\\my_server_directory\\my_pfx_file.pfx", "my password", "CN=Me"); AS1Receiver1.SignerCert = (base 64 encoded certificate); AS1Receiver1.LogDirectory = "c:\\my_server_directory\\my_log_directory"; AS1Receiver1.ProcessRequest(); AS1Receiver1.SendResponse(); AS1Receiver1.Disconnect(); Additional functionality allows the user to examine details of the client's request, to permit certain types of errors, or to customize the outgoing MDN. See the property and method list for details.

Attachments Property (AS1Receiver Component)

Collection of files attached to the current message.

Syntax

• C#
• VB.NET

public EDIAttachmentList Attachments { get; }

Public ReadOnly Property Attachments As EDIAttachmentList

Remarks

When a message is received, the component will write all of the files attached to the EDIData into temp files. These attachments can be retrieved by walking this collection and retrieving their file names.

This property is read-only and not available at design time.

Certificate Property (AS1Receiver Component)

The decryption and receipt signing certificate.

Syntax

• C#
• VB.NET

public Certificate Certificate { get; set; }

Public Property Certificate As Certificate

Remarks

The digital certificate that the component will use to decrypt incoming transmissions and sign the MDN receipt (if requested). If a different certificate is required for decryption than for MDN signing, set the decryption certificate before calling ParseRequest, then set the signing certificate before calling CreateMDNReceipt. Certificate must be set to a private key certificate.

CompressionFormat Property (AS1Receiver Component)

The compression format used on the incoming message.

Syntax

• C#
• VB.NET

public AS1ReceiverCompressionFormats CompressionFormat { get; }

enum AS1ReceiverCompressionFormats {
  cfNone,
  cfZLIB
}

Public ReadOnly Property CompressionFormat As As1receiverCompressionFormats

Enum AS1ReceiverCompressionFormats
  cfNone
  cfZLIB
End Enum

Default Value

The EDI data sent in Request .

Syntax

• C#
• VB.NET

public EDIData EDIData { get; }

Public ReadOnly Property EDIData As EDIData

Remarks

This property will only be populated if ParseRequest or ProcessRequest finishes without an error, setting ScanResult to 0. If so, EDIData will contain the processed EDI message.

This property is read-only.

Firewall Property (AS1Receiver Component)

A set of properties related to firewall access.

Syntax

• C#
• VB.NET

public Firewall Firewall { get; set; }

Public Property Firewall As Firewall

Remarks

This is a Firewall-type property, which contains fields describing the firewall through which the component will attempt to connect.

From Property (AS1Receiver Component)

The sender of the original message.

Syntax

• C#
• VB.NET

public string From { get; set; }

Public Property From As String

Default Value

""

Remarks

The sender of the original message. The recipient is given by SendTo.

Note that From and SendTo correspond to the sender and recipient of the original message. For MDNs the roles are reversed, so that From indicates the recipient, and SendTo indicates the sender of the MDN.

LocalHost Property (AS1Receiver Component)

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

Syntax

• C#
• VB.NET

public string LocalHost { get; set; }

Public Property LocalHost As String

Default Value

""

Remarks

This 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 multihomed hosts (machines with more than one IP interface) setting LocalHost to the IP address of an interface will make the component initiate connections (or accept in the case of server components) only through that interface. It is recommended to provide an IP address rather than a hostname when setting this property to ensure the desired interface is used.

If the component 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 multihomed 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 (AS1Receiver Component)

The path to a directory for logging.

Syntax

• C#
• VB.NET

public string LogDirectory { get; set; }

Public Property LogDirectory As String

Default Value

""

Remarks

Setting LogDirectory will instruct the component to log the details of each transmission to unique files in the specified directory. For each request processed, the component will log the original EDI data, the complete text of the outgoing request and the incoming response.

The component will write a file for each transmission, with extension ".log". In case of error an additional file will be written with extension ".err", and the error will be reported in both files. Raw AS1 messages created or downloaded by the component will be written with extension ".as1", and MDNs created or downloaded will be written with extension ".as1-mdn".

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

If logs cannot be written an exception will be thrown.

LogFile Property (AS1Receiver Component)

The log file written.

Syntax

• C#
• VB.NET

public string LogFile { get; }

Public ReadOnly Property LogFile As String

Default Value

""

Remarks

In case LogDirectory is specified two log files will be written in the specified directory and LogFile will contain the path.

LogFile will in fact refer to several files with appropriate extensions. A diagnostic log will be written with filename LogFile + ".log", and any EDI data read will be written with filename LogFile + ".dat". Raw AS1 messages and MDNs will also be written with extensions ".as1" and ".as1-mdn".

This property is read-only.

MailServer Property (AS1Receiver Component)

The address of your mail server.

Syntax

• C#
• VB.NET

public string MailServer { get; set; }

Public Property MailServer As String

Default Value

""

Remarks

The address of your mail server. By default, the component will send outgoing mail via SMTP, and receive incoming mail via POP. Moreover, the component will assume that both servers are located at the address specified by MailServer.

In case you use different addresses for incoming and outgoing mail you should set the POPServer and SMTPServer configuration settings appropriately. You may also set POPPort and SMTPPort in case you use nonstandard ports.

To configure SSL you should set SSLStartMode. Note that if SSL is used for sending but not receiving, or vice versa, you should set SSLStartMode each time you send or receive a file.

MDNReceipt Property (AS1Receiver Component)

The MDN-based receipt generated by the component.

Syntax

• C#
• VB.NET

public MDNReceipt MDNReceipt { get; set; }

Public Property MDNReceipt As MDNReceipt

Remarks

After invoking CreateMDNReceipt, MDNReceipt will contain the entire text of the receipt to be returned to the client. It will report either success or failure depending on ScanResult; in either case it will be RFC-compliant and suitable for returning to the client.

The MDNReceipt will consist of the MDN itself, a human-readable message, MIME headers and footers, and a signature if applicable. The receipt may be generated by invoking CreateMDNReceipt and customized further by setting the parameters to CreateMDNReceipt.

A variety of configuration settings may be used to override the default generation of the outgoing MDN. The MIC algorithm used in the MDN may be set with MDNMICAlgorithm;. MDNReportingUA specifies the reporting agent, and MDNSendingMode may be used to specify the "disposition-mode" field in the MDN.

The signature, if any, will use the protocol specified by the ReceiptSigningProtocol configuration setting, and the certificate specified.

Error reporting may be controlled by configuring ErrorReportingFlags. By default, any errors will cause MDNReceipt to report a failure to process the message (either "failed/Failure" or "processed/Error" will be reported, according to the specification and the type of error). Setting ErrorReportingFlags will cause the MDNReceipt to overlook the chosen types of errors. If all errors are overlooked, the MDNReceipt will report success and calculate a MIC on the original message as usual. A warning may be reported by setting the MDNWarning configuration setting.

MDNReceipt will always be generated by the component; however, if MDNTo is empty, an MDN-based receipt has not been requested. One may be sent anyway at the option of the server. If MDNTo is nonempty, the receipt MUST be returned according to RFC specifications. In AS2, the MDN should be returned in the body of the HTTP reply, or if ReceiptDeliveryOption is nonempty, to the URL specified there instead. In AS3, the MDN should be returned to the URL specified in MDNTo.

MDNTo Property (AS1Receiver Component)

The recipient for the Message Disposition Notification (MDN).

Syntax

• C#
• VB.NET

public string MDNTo { get; }

Public ReadOnly Property MDNTo As String

Default Value

""

Remarks

MDNTo corresponds to the Disposition-Notification-To header of RequestHeaders. If nonempty, the client has requested an MDN receipt (typically the actual value is irrelevant). This receipt will be generated in a call to ProcessRequest or CreateMDNReceipt, and may be sent by calling SendResponse.

The receipt will be contained in MDNReceipt. If ReceiptDeliveryOption is empty, the receipt should be synchronously delivered in the HTTP response; otherwise, it should be delivered asynchronously to the URL specified. In either case, SendResponse will send the response as appropriate.

According to RFC specifications, MDNReceipt must be sent if requested by the client. If MDNTo is empty the MDN may be sent or not at the option of the server.

This property is read-only.

MessageId Property (AS1Receiver Component)

The message ID of the incoming message.

Syntax

• C#
• VB.NET

public string MessageId { get; }

Public ReadOnly Property MessageId As String

Default Value

""

Remarks

MessageId corresponds to the Message-Id header of Request, and will be used as the Original-Message-Id header of MDNReceipt.

This property is read-only.

Password Property (AS1Receiver Component)

The password for your incoming mail server.

Syntax

• C#
• VB.NET

public string Password { get; set; }

Public Property Password As String

Default Value

""

Remarks

The password for your incoming mail server. Set this before invoking Connect.

Request Property (AS1Receiver Component)

The AS1 request to be processed.

Syntax

• C#
• VB.NET

public string Request { get; set; }
public byte[] RequestB { get; set; }

Public Property Request As String
Public Property RequestB As Byte()

Default Value

""

Remarks

You may specify the request manually, or you may load the request from the mail server by invoking ReadRequest.

The headers generally should be specified separately in RequestHeaders.

RequestHeaders Property (AS1Receiver Component)

The headers in the AS1 request.

Syntax

• C#
• VB.NET

public HeaderList RequestHeaders { get; }

Public Property RequestHeaders As HeaderList

Remarks

The headers will include any and all headers attached by the mail server(s).

RequestHeadersString Property (AS1Receiver Component)

Syntax

• C#
• VB.NET

public string RequestHeadersString { get; set; }

Public Property RequestHeadersString As String

Default Value

""

Remarks

ScanResult Property (AS1Receiver Component)

The result of invoking ParseRequest .

Syntax

• C#
• VB.NET

public int ScanResult { get; }

Public ReadOnly Property ScanResult As Integer

Default Value

0

Remarks

ScanResult will contain information about any errors that occurred while invoking ParseRequest or ProcessRequest. ScanResult will contain 0 if no errors occurred, otherwise it will contain one or more of the following errors. If multiple errors are reported the results will be OR-ed together.

This property is read-only.

SendTo Property (AS1Receiver Component)

The recipient of the original message.

Syntax

• C#
• VB.NET

public string SendTo { get; set; }

Public Property SendTo As String

Default Value

""

Remarks

The recipient of the original message. The originator is given by From.

Note that From and SendTo correspond to the sender and recipient of the original message. For MDNs the roles are reversed, so that From indicates the recipient, and SendTo indicates the sender of the MDN.

SignerCert Property (AS1Receiver Component)

Your trading partner's certificate.

Syntax

• C#
• VB.NET

public Certificate SignerCert { get; set; }

Public Property SignerCert As Certificate

Remarks

You must set your trading partner's certificate before processing any signed messages. This property should be set to a public key certificate.

If the trading partner's identity is unknown, you should first invoke ReadRequest and read the value of AS2To (or for AS3, AS3To). This will allow you to determine the correct certificate to use.

As a special case, you may set AcceptAnySignerCert to true. In this case, the component will attempt to validate the signature without knowing the certificate in advance. This is not recommended for production use, as it poses a security risk.

This property is not available at design time.

SSLAcceptServerCert Property (AS1Receiver Component)

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

Syntax

• C#
• VB.NET

public Certificate SSLAcceptServerCert { get; set; }

Public Property SSLAcceptServerCert As Certificate

Remarks

If it finds any issues with the certificate presented by the server, the component 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.

Note: This functionality is provided only for cases in which 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.

SSLCert Property (AS1Receiver Component)

The certificate to be used during Secure Sockets Layer (SSL) negotiation.

Syntax

• C#
• VB.NET

public Certificate SSLCert { get; set; }

Public Property SSLCert As Certificate

Remarks

This property includes the digital certificate that the component will use during SSL negotiation. Set this property to a valid certificate before starting SSL negotiation. To set a certificate, you may set the Encoded field to the encoded certificate. To select a certificate, use the store and subject fields.

SSLProvider Property (AS1Receiver Component)

The Secure Sockets Layer/Transport Layer Security (SSL/TLS) implementation to use.

Syntax

• C#
• VB.NET

public AS1ReceiverSSLProviders SSLProvider { get; set; }

enum AS1ReceiverSSLProviders {
  sslpAutomatic,
  sslpPlatform,
  sslpInternal
}

Public Property SSLProvider As As1receiverSSLProviders

Enum AS1ReceiverSSLProviders
  sslpAutomatic
  sslpPlatform
  sslpInternal
End Enum

Default Value

0

Remarks

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 component 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 as follows:

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

When Automatic is selected, on Windows, the component will use the platform implementation. On Linux/macOS, the component will use the internal implementation. When TLS 1.3 is enabled via SSLEnabledProtocols, the internal implementation is used on all platforms.

The .NET Standard library will always use the internal implementation on all platforms.

SSLServerCert Property (AS1Receiver Component)

The server certificate for the last established connection.

Syntax

• C#
• VB.NET

public Certificate SSLServerCert { get; }

Public ReadOnly Property SSLServerCert As Certificate

Remarks

SSLServerCert is reset every time a new connection is attempted.

This property is read-only.

SSLStartMode Property (AS1Receiver Component)

Determines how the component starts the SSL negotiation. By default, SSL will not be used.

Syntax

• C#
• VB.NET

public AS1ReceiverSSLStartModes SSLStartMode { get; set; }

enum AS1ReceiverSSLStartModes {
  sslAutomatic,
  sslImplicit,
  sslExplicit,
  sslNone
}

Public Property SSLStartMode As As1receiverSSLStartModes

Enum AS1ReceiverSSLStartModes
  sslAutomatic
  sslImplicit
  sslExplicit
  sslNone
End Enum

Default Value

Config Method (AS1Receiver Component)

Sets or retrieves a configuration setting.

Syntax

• C#
• VB.NET

public string Config(string configurationString);

Async Version
public async Task<string> Config(string configurationString);
public async Task<string> Config(string configurationString, CancellationToken cancellationToken);

Public Function Config(ByVal ConfigurationString As String) As String

Async Version
Public Function Config(ByVal ConfigurationString As String) As Task(Of String)
Public Function Config(ByVal ConfigurationString As String, cancellationToken As CancellationToken) As Task(Of String)

Remarks

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

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

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

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

Connect Method (AS1Receiver Component)

Connects to the incoming mail server.

Syntax

• C#
• VB.NET

public void Connect();

Async Version
public async Task Connect();
public async Task Connect(CancellationToken cancellationToken);

Public Sub Connect()

Async Version
Public Sub Connect() As Task
Public Sub Connect(cancellationToken As CancellationToken) As Task

Remarks

Connects to the incoming mail server specified by MailServer. You must set User and Password prior to calling Connect. The connection will be maintained until you call Disconnect.

If you wish to connect in SSL you should first set the SSLStartMode property. Note that it is not necessary to explicitly connect to an SMTP server for outgoing mail; a connection will be created and destroyed each time a mail is sent.

CreateMDNReceipt Method (AS1Receiver Component)

Creates MDNReceipt .

Syntax

• C#
• VB.NET

public void CreateMDNReceipt(string headers, string MDN, string message);

Async Version
public async Task CreateMDNReceipt(string headers, string MDN, string message);
public async Task CreateMDNReceipt(string headers, string MDN, string message, CancellationToken cancellationToken);

Public Sub CreateMDNReceipt(ByVal Headers As String, ByVal MDN As String, ByVal Message As String)

Async Version
Public Sub CreateMDNReceipt(ByVal Headers As String, ByVal MDN As String, ByVal Message As String) As Task
Public Sub CreateMDNReceipt(ByVal Headers As String, ByVal MDN As String, ByVal Message As String, cancellationToken As CancellationToken) As Task

Remarks

CreateMDNReceipt may be invoked after ParseRequest to create an MDN-based receipt. The receipt will report success or failure depending on ErrorReportingFlags and the success or failure of ParseRequest.

This method populates MDNReceipt with a new MDNReceipt. The Headers, MDN, and Message parameters can be used to further customize the receipt, or empty string ("") parameters may be set to use the component generated defaults. Headers will set additional transport headers to be sent with the receipt (in the HTTP or SMTP headers of the signed receipt). MDN can be used to append additional headers to the Message Disposition Notification portion of the MDN Receipt. If MDN is set to a value prefixed with an at sign ("@"), the at sign will be removed and the specified MDN will be used in the receipt in place of the component generated value. Message will set the human-readable portion of the receipt, and should describe any error conditions that may have occurred.

DeleteMessage Method (AS1Receiver Component)

Deletes the message specified by MailMessageNumber .

Syntax

• C#
• VB.NET

public void DeleteMessage();

Async Version
public async Task DeleteMessage();
public async Task DeleteMessage(CancellationToken cancellationToken);

Public Sub DeleteMessage()

Async Version
Public Sub DeleteMessage() As Task
Public Sub DeleteMessage(cancellationToken As CancellationToken) As Task

Remarks

Requests that the MailServer delete the message specified by MailMessageNumber. The message will not actually be deleted until the connection is closed.

Disconnect Method (AS1Receiver Component)

Disconnects from the incoming mail server.

Syntax

• C#
• VB.NET

public void Disconnect();

Async Version
public async Task Disconnect();
public async Task Disconnect(CancellationToken cancellationToken);

Public Sub Disconnect()

Async Version
Public Sub Disconnect() As Task
Public Sub Disconnect(cancellationToken As CancellationToken) As Task

Remarks

ParseRequest Method (AS1Receiver Component)

Parses the EDI message and determines the EDIData .

Syntax

• C#
• VB.NET

public void ParseRequest();

Async Version
public async Task ParseRequest();
public async Task ParseRequest(CancellationToken cancellationToken);

Public Sub ParseRequest()

Async Version
Public Sub ParseRequest() As Task
Public Sub ParseRequest(cancellationToken As CancellationToken) As Task

Remarks

Processes the EDI message in the request (either from the HTTP context, or as given by Request and possibly RequestHeadersString). If the message is encrypted, it will be decrypted with the certificate specified in Certificate. If it is signed, the signature will be verified against the certificate specified in SignerCert.

If the message is scanned without difficulty, EDIData will be populated. If a problem occurs, an exception will be thrown. This might occur if the client used or requested unsupported algorithms or data formats. In this case, EDIData will not be determined.

The component may be configured to ignore certain errors by setting ErrorProcessingFlags. This will allow the message to be processed and EDIData to be determined. If any errors occur, an exception will be thrown and the ScanResult property will reflect the error condition.

Whether or not an exception is thrown, an MDNReceipt may be generated by invoking CreateMDNReceipt. In the case of a successful scan MDNReceipt will report the success, otherwise the receipt will provide information to the client about the error.

ProcessRequest may be used to scan and create the receipt in one step. ReadRequest may be used to scan the request headers only to obtain details that can be used to configure the correct settings for the partner.

ProcessQueue Method (AS1Receiver Component)

Remarks

Invoking ProcessRequest automates the entire AS2 server process. The method scans the request, determines the EDIData, and generates the MDNReceipt. In a server environment the receipt may be returned by invoking SendResponse.

The method's functionality is the same as the combined functionality of ParseRequest and CreateMDNReceipt. The method's operation is controlled by ErrorProcessingFlags and ErrorReportingFlags, and ScanResult will be populated as in ParseRequest.

The method will throw an exception, as ParseRequest does, if a problem is found while processing the request. However, if the problem does not prevent an MDN from being generated, MDNReceipt will still be generated before the exception is thrown. In all cases, the receipt will be suitable for returning to the client. If an exception is thrown, the MDNReceipt will provide more detail on the cause of the error.

The component will populate EDIData if no errors occurred scanning the request, or if ErrorProcessingFlags had been previously configured to allow the error.

  public byte[] CertEncodedB { get; }
}

Public Event OnSignerCertInfo As OnSignerCertInfoHandler

Public Delegate Sub OnSignerCertInfoHandler(sender As Object, e As AS1ReceiverSignerCertInfoEventArgs)

Public Class AS1ReceiverSignerCertInfoEventArgs Inherits EventArgs
  Public ReadOnly Property Issuer As String
  Public ReadOnly Property SerialNumber As String
  Public ReadOnly Property SubjectKeyIdentifier As String
  Public ReadOnly Property CertEncoded As String
  Public ReadOnly Property CertEncodedB As Byte()
End Class

Remarks

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

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

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

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

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

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

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

SSLServerAuthentication Event (AS1Receiver Component)

Fired after the server presents its certificate to the client.

Syntax

• C#
• VB.NET

public event OnSSLServerAuthenticationHandler OnSSLServerAuthentication;

public delegate void OnSSLServerAuthenticationHandler(object sender, AS1ReceiverSSLServerAuthenticationEventArgs e);

public class AS1ReceiverSSLServerAuthenticationEventArgs : EventArgs {
  public string CertEncoded { get; }
  public byte[] CertEncodedB { get; }
  public string CertSubject { get; }
  public string CertIssuer { get; }
  public string Status { get; }
  public bool Accept { get; set; }
}

Public Event OnSSLServerAuthentication As OnSSLServerAuthenticationHandler

Public Delegate Sub OnSSLServerAuthenticationHandler(sender As Object, e As AS1ReceiverSSLServerAuthenticationEventArgs)

Public Class AS1ReceiverSSLServerAuthenticationEventArgs Inherits EventArgs
  Public ReadOnly Property CertEncoded As String
  Public ReadOnly Property CertEncodedB As Byte()
  Public ReadOnly Property CertSubject As String
  Public ReadOnly Property CertIssuer As String
  Public ReadOnly Property Status As String
  Public Property Accept As Boolean
End Class

Remarks

During this event, the client can decide whether or not to continue with the connection process. 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 or not to continue.

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 (AS1Receiver Component)

Fired when secure connection progress messages are available.

Syntax

• C#
• VB.NET

public event OnSSLStatusHandler OnSSLStatus;

public delegate void OnSSLStatusHandler(object sender, AS1ReceiverSSLStatusEventArgs e);
