The AS2Sender component implements an AS2 / EDI-INT client.

Syntax

TibeAS2Sender

Remarks

The AS2Sender component may be used to send EDI or other messages over HTTP/S, using the AS2 protocol. It may also be used to verify synchronous or asynchronous server responses.

A typical AS2 transaction is as follows:

(1) The sender sends an EDI document to the receiver using HTTP or HTTPS. Typically the document will be signed and encrypted (particularly if SSL is not used). A signed receipt will also be requested.

(2) The receiver decrypts the message and verifies the signature.

(3) The receiver sends a signed receipt back to the client. The signature is over the hash of an MDN, which contains a hash of the received message.

When sending an EDI message, the client should specify, at a minimum, AS2From and AS2To, URL, and EDIData. The Post method should then be invoked.

To secure the EDI transmission, the message may be signed and/or encrypted by setting the appropriate certificates. By default, the component will apply message security if the appropriate certificates are specified. To sign the data, set SigningCert. To encrypt, set RecipientCerts. If the recipient uses different certificates for signing and encryption it will also be necessary to set ReceiptSignerCert.

SSL will also be used if the scheme in URL is "https". If your trading partner is using a self-signed certificate, it will be necessary to set SSLAcceptServerCert or trap the SSLServerAuthentication event to accept the certificate.

The message may also be compressed by setting CompressionFormat.

To request a receipt, or Message Disposition Notification (MDN), simply set the MDNTo property. The MDNOptions property may be used to customize the request. By default, the component will request a signed MDN over an SHA1 hash.

The component supports both synchronous and asynchronous MDN receipt delivery. By default, the component requests synchronous MDN receipt delivery, and the MDN will be returned in the HTTP reply. To request asynchronous MDN delivery, set the MDNDeliveryOption to the URL where MDN's are to be delivered.

The HTTP reply will automatically be processed by the component. If an MDN was requested, Post will validate the MDN and (if signed) establish non-repudiation of receipt. Any errors or warnings will cause the component to throw an exception.

In either case, after the EDI transaction is processed successfully, the MDNReceipt will be populated with the appropriate values.

Validating Asynchronous MDNs

The component may also be used to process and verify asynchronous MDNs. To do this, you should invoke ReadAsyncReceipt. This will read the receipt from the current HTTP context (or from MDNReceipt, if set manually), and allow you to determine your trading partner's identity and the message ID. You should then set ReceiptSignerCert and OriginalContentMIC, and finally invoke VerifyReceipt.

Path to a directory to store data used in verifying AsyncMDNs.

Syntax

property AsyncMDNInfoDir: String read get_AsyncMDNInfoDir write set_AsyncMDNInfoDir;

Default Value

''

Remarks

If Post is invoked after setting AsyncMDNInfoDir and an asynchronous MDN is requested, the component stores the data required to verify AsyncMDNs in a file in the specified directory. The name of the file is the MessageId of the outgoing message.

AsyncMDNInfoDir is also used while verifying asynchronous MDNs using VerifyReceipt. The properties required to process AsyncMDNs, namely OriginalContentMIC and MDNOptions, are automatically read from the file saved at the time of sending the original message.

Attachments Property (AS2Sender Component)

Collection of files attached to the current message.

Syntax

property Attachments: TibeEDIAttachmentList read get_Attachments write set_Attachments;

Remarks

When a call to Send is made, the component will attach the files referenced by each EDIAttachment in this collection to the EDIData.

This property is not available at design time.

CEMDetails Property (AS2Sender Component)

A collection of Certificate Exchange Messaging (CEM) details.

Syntax

property CEMDetails: TibeCEMDetailList read get_CEMDetails write set_CEMDetails;

Remarks

This collection holds Certificate Exchange Messaging (CEM) details. The details define the certificate, respond-by-date, and more.

TibeTCompressionFormats = (
  cfNone,
  cfZLIB
);

Default Value

cfNone

Remarks

By default, outgoing data will not be compressed. Setting this property will instruct the component to compress the outgoing data using the indicated format.

Compression is highly recommended for large messages, as it will reduce network bandwidth and processing time required.

The compression algorithm used is Zlib, as required by RFC 3274 and defined in RFCs 1950 and 1951.

Cookies Property (AS2Sender Component)

This property includes a collection of cookies.

This property is not available at design time.

EncryptionAlgorithm Property (AS2Sender Component)

The algorithm used to encrypt the EDI data.

Syntax

property EncryptionAlgorithm: String read get_EncryptionAlgorithm write set_EncryptionAlgorithm;

Default Value

'3DES'

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

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

Possible values are:

• 3DES (default)
• DES
• AESCBC128
• AESCBC192
• AESCBC256
• AESGCM128
• AESGCM192
• AESGCM256

Etag Property (AS2Sender Component)

The Etag of the file being sent.

Syntax

property Etag: String read get_Etag write set_Etag;

Default Value

''

Remarks

This specifies the Etag for the file. This value should be set to an empty string the first time a file is sent using the Restart command. The component will generate a unique Etag based on the processed contents of the file and set this property when sending begins.

If a file is interrupted, this value must be set when Restart is called to resume transfer of the already processed file.

Firewall Property (AS2Sender Component)

A set of properties related to firewall access.

Syntax

property Firewall: TibeFirewall read get_Firewall write set_Firewall;

Remarks

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

From Property (AS2Sender Component)

The email address of the HTTP agent (optional).

Syntax

property From: String read get_From write set_From;

Default Value

''

Remarks

If the From property contains a non-empty string, an HTTP From: header is added to the request. This header generally gives the email address of the requester of the document.

This property is not available at design time.

LocalHost Property (AS2Sender Component)

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

Syntax

property LocalHost: String read get_LocalHost write set_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 component initiate connections (or accept in the case of server components) only through that interface.

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 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.

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 component initiate connections (or accept in the case of server components) only through that interface.

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 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 (AS2Sender Component)

The path to a directory for logging.

Syntax

property LogDirectory: String read get_LogDirectory write set_LogDirectory;

Default Value

''

Remarks

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

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

One or more of these logs may be disabled by setting the LogOptions configuration setting.

LogDirectory supports several macros that can be used to specify a unique directory path. If the path specified does not already exist, the component will attempt to create the directory. The following macros are supported:

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

If logs cannot be written an exception will be thrown.

LogFile Property (AS2Sender Component)

The log file written.

Syntax

property LogFile: String read get_LogFile;

Default Value

''

Remarks

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

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

This property is read-only.

MDNDeliveryOption Property (AS2Sender Component)

A URL indicating how the receipt is to be delivered.

Syntax

property MDNDeliveryOption: String read get_MDNDeliveryOption write set_MDNDeliveryOption;

Default Value

''

Remarks

The default mode of operation is for the receipt to be returned synchronously within the HTTP reply. By specifying a valid URL, the user may request asynchronous delivery instead. The URL indicates the destination for the reply, and may use any appropriate protocol, such as "http", "https", or "mailto".

If MDNDeliveryOption is set to an empty string, the receipt will be returned synchronously, and will be processed automatically by the component. Clients requesting asynchronous delivery should provide their own processing for reading receipts.

MDNOptions Property (AS2Sender Component)

Used to indicate the options requested for the MDN receipt.

Syntax

property MDNOptions: String read get_MDNOptions write set_MDNOptions;

Default Value

'signed-receipt-protocol=optional, pkcs7-signature; signed-receipt-micalg=optional, sha-256'

Remarks

By default, the component will request that the MDN be signed with a PKCS#7 signature over a SHA-256 hash, which is the industry standard.

Set MDNOptions to an empty string to request an unsigned receipt.

This property will automatically be updated when SignatureAlgorithm is set. Normally you will not need to set this property, however you can set a value here to override the automatically generated value.

The string format is that of the Disposition-Notification-Options HTTP header, as specified in RFC 3335. As a form of shorthand, you may set this property to "sha1", "sha-256", or "md5" to request the indicated hash algorithm.

MDNReceipt Property (AS2Sender Component)

The MDN receipt returned from the server.

Syntax

property MDNReceipt: TibeMDNReceipt read get_MDNReceipt write set_MDNReceipt;

Remarks

This property will contain an instance of MDNReceipt with the complete MDN receipt returned from the AS2 receiver. The receipt will be a signed or unsigned multipart/report in MIME format. For synchronous MDN requests, this property is populated automatically after the call to Post. If an asynchronous MDN is sent over HTTP, it may be read from the HTTP context by calling ReadAsyncReceipt, or it may be set manually.

When MDNReceipt is set to a valid MDN receipt, the originator of the receipt will be stored in AS2To, the intended recipient (presumably your system) will be stored in AS2From, and the original message ID will be stored in MessageId.

If you are processing a MDN receipt asynchronously, you can use the values to look up the original message and validate the receipt. Set the OriginalContentMIC, MDNOptions, and ReceiptSignerCert to the values originally computed when the message was sent (if you are requesting async MDNs you must save this information externally.). You can then validate the asynchronous receipt by invoking VerifyReceipt.

Alternatively, AsyncMDNInfoDir may be set in place of OriginalContentMIC, MessageId, and MDNOptions (provided it was set to the same value when the message was sent). If AsyncMDNInfoDir was specified when the message was sent, the component would have saved OriginalContentMIC and MDNOptions to a file identified by the MessageId for the transmission. These properties are read from the file matching the MessageId in the MDNReceipt automatically if AsyncMDNInfoDir is specified.

Note: MDNReceipt must be populated prior to calling VerifyReceipt.

MDNTo Property (AS2Sender Component)

Used to indicate that a message disposition notification is requested.

Syntax

property MDNTo: String read get_MDNTo write set_MDNTo;

Default Value

''

Remarks

If this property is set, a Disposition-Notification-To header will be added to the request, and an MDN will be requested. The value may be an email address, URL, etc., and while its presence is used to determine whether or not an MDN is sent, the value itself will typically be ignored by the server.

By default, the component will request a PKCS#7 signature and synchronous delivery. You may set MDNDeliveryOption to request an asynchronous MDN, and you may set MDNOptions to request a different type of signature, or no signature at all.

MessageId Property (AS2Sender Component)

The Id of the message.

Syntax

property MessageId: String read get_MessageId write set_MessageId;

Default Value

''

Remarks

The Id format is as in RFC 2822: id-left@id-right .

A unique Id will automatically be generated on startup. Sending a message will reset id-left if the MessageId has been used in the previous message.

If you set MessageId to a string of the form "@(id-right)" a unique id-left will be generated. If you set MessageId to an empty string, a new MessageId will be generated with the same id-right.

After an MDNReceipt is returned or set, MessageId will contain the Original-Message-ID found in the MDN Receipt.

This property is not available at design time.

OriginalContentMIC Property (AS2Sender Component)

The Message Integrity Check(s) (one-way hash) of the outgoing message.

Syntax

property OriginalContentMIC: String read get_OriginalContentMIC write set_OriginalContentMIC;

Default Value

''

Remarks

A MIC will be calculated over the outgoing message using the same algorithm in the SignatureAlgorithm configuration used to sign the message. The property will be set when Post (in AS3, Send) is invoked, and the MIC will automatically be checked against the Original-Content-MIC in the MDN for synchronous MDNs.

The format is in RFC 3335, i.e. "w7AguNJEmhF/qIjJw6LnnA==, md5", with a newline at the end.

If you are requesting an asynchronous MDN, you must save this value externally so that it can be loaded when the MDN is received (you may also use AsyncMDNInfoDir).

Proxy Property (AS2Sender Component)

This property includes a set of properties related to proxy access.

Syntax

property Proxy: TibeProxy read get_Proxy write set_Proxy;

Remarks

This property contains fields describing the proxy through which the component will attempt to connect.

Syntax

property ReceiptSignerCertEncoded: String read get_ReceiptSignerCertEncoded write set_ReceiptSignerCertEncoded;
property ReceiptSignerCertEncodedB: TBytes read get_ReceiptSignerCertEncodedB write set_ReceiptSignerCertEncodedB;

Default Value

''

Remarks

This is the certificate (PEM/base64 encoded). This property is used to assign a specific certificate. The Store and Subject properties also may be used to specify a certificate.

When Encoded is set, a search is initiated in the current Store for the private key of the certificate. If the key is found, Subject is updated to reflect the full subject of the selected certificate; otherwise, Subject is set to an empty string.

This property is not available at design time.

TibeTSSLProviders = (
  sslpAutomatic,
  sslpPlatform,
  sslpInternal
);

Default Value

sslpAutomatic

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:

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.

SSLServerCertEncoded Property (AS2Sender Component)

Timeout Property (AS2Sender Component)

A timeout for the component.

Syntax

property Timeout: Integer read get_Timeout write set_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 component will wait for the operation to complete before returning control.

The component 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 component raises 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.

URL Property (AS2Sender Component)

The URL to which the request is made.

Syntax

property URL: String read get_URL write set_URL;

Default Value

'IPWorks EDI AS2Sender Component - www.nsoftware.com'

Remarks

You may override the default with the name and version of your software.

Config Method (AS2Sender Component)

Sets or retrieves a configuration setting.

Syntax

function Config(ConfigurationString: String): String;

Remarks

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

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

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

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

DoEvents Method (AS2Sender Component)

Processes events from the internal message queue.

Syntax

procedure DoEvents();

Remarks

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

Interrupt Method (AS2Sender Component)

Interrupt the current method.

Syntax

procedure Interrupt();

Remarks

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

Post Method (AS2Sender Component)

Post data to the AS2 server, and check the receipt.

Syntax

procedure Post();

Remarks

Post data to the server. The reply will also be checked, and if a synchronous MDN was requested (i.e., MDNTo is not empty), it will be validated. After the method finishes, the MDNReceipt, ReceiptSigningProtocol, and ReceiptSignerCert properties will be populated with the appropriate values.

The method operates synchronously, and will throw an exception if any errors or warnings occur. Errors might include a failure to decrypt or authenticate the receipt, the absence of an MDN when one was requested, TCP/IP errors, or any errors reported by the server in the MDN. Warnings might include the return of an unsigned receipt when a signed receipt was requested, or other warnings reported by the server in the MDN.

If an exception is thrown the error code will correspond to the severity of the warning or error, allowing client software to determine whether or not to accept the reply. If multiple errors occur, the exception will return a special error code, and the error message will contain a line for each error's code and description; i.e. "423: Failed to authenticate sender". If the error(s) is/are not fatal processing will not be interrupted, and the relevant properties will be populated as normal.

ReadAsyncReceipt Method (AS2Sender Component)

Reads an asynchronous MDN receipt from the current HTTP session.

Syntax

procedure ReadAsyncReceipt();

Remarks

ReadAsyncReceipt is used to read an asynchronous MDN receipt from the . The component will fetch the request stream from the HTTP session. MDNReceipt will be populated with a new instance of MDNReceipt.

Reset Method (AS2Sender Component)

Syntax

procedure Reset();

Remarks

Resets all HTTP headers as well as EDIData, etc. After invoking this method the component may be reused as if it were newly created.

Restart Method (AS2Sender Component)

Restart sending of the file specified by the Etag property.

Syntax

procedure Restart();

Remarks

This method should be called when using the AS2 restart functionality. When called, the component will process the file and cache the processed contents to the RestartDirectory. Before sending, the Etag property will be populated with a unique Etag which identifies the processed file.

If sending is interrupted or fails, this method should be called to restart sending of the previously processed file starting where the interruption occurred. In order to restart from the last transfer, the Etag must be populated with the value from the last connection.

NOTE: When using restart functionality, the data is completely processed to the RestartDirectory before sending begins.

SendCEMRequest Method (AS2Sender Component)

Sends a Certificate Exchange Messaging (CEM) request.

Syntax

procedure SendCEMRequest(RequestId: String);

Remarks

This method send the Certificate Exchange Messaging (CEM) request with the details specified in CEMDetails.

Certificate Exchange Messaging (CEM) allows for new certificates to be sent to a recipient and be automatically updated. This removes the requirement to manually send new certificates to a partner via email or other means. When both sides support this functionality updating certificates can be accomplished in a short period of time.

To prepare a CEM request populate the CEMDetails collection with at least one certificate. For instance if the certificate of the application will be updated soon, the CEMDetails may be populated with the corresponding public certificate to be sent to your partner. CEMDetails should only contain public certificates.

Set RespondByDate to the date by which you expect a response. The format is of the XML standard dateTime type expressed in local time with UTC offset. For instance: "2005-08-31T00:21:00-05:00".

Optionally set CertId to a friendly identifier that the partner may use to help understand the purpose of the new certificate. For instance "New.Encryption.Cert.2014".

Set ResponseURL to the publicly accessible URL where the CEM response will be sent after the partner processes it.

The RequestId parameter uniquely identifies this CEM request and must be saved for use later when receiving the CEM response.

When calling this method the applicable CEMDetails properties are:

• CertStoreType
• CertStore
• CertStorePassword
• CertSubject
• RespondByDate
• ResponseURL
• CertUsage (optional)
• CertId (optional)

SendCEMResponse Method (AS2Sender Component)

Sends a Certificate Exchange Messaging (CEM) response.

Syntax

procedure SendCEMResponse(RequestId: String);

Remarks

This method send the Certificate Exchange Messaging (CEM) request with the details specified in CEMDetails.

A CEM request must have previously been received using AS2Receiver. To send the CEM response, populate CEMDetails with the certificate information and decide whether to accept or reject the request. The following properties may be set to specify the certificate:

• CertStoreType
• CertStore
• CertSubject

• CertIssuer
• CertSerialNumber

After specifying the certificate information choose whether to accept or reject the request. To accept the request set Accepted to True. To reject the request set Accepted to False and specify a reason in RejectionReason.

Call SendCEMResponse and pass the CEM request Id that was retrieved from the request.

SetRequestHeader Method (AS2Sender Component)

Allows the user to set or add arbitrary HTTP request headers.

Syntax

procedure SetRequestHeader(HeaderName: String; HeaderValue: String);

Remarks

HeaderName should contain the header name, and HeaderValue should contain its value. Use this to set headers such as To, Date, etc. Note that a default value for Date will automatically be determined and this method may be used to override the default.

SetRequestHeader may be used to set any header except for the following: AS2-To, AS2-From, AS2-Version, Subject, Message-Id, Disposition-Notification-To, Disposition-Notification-Options, Receipt-Delivery-Option, Host, Content-Length.

SetTPInfo Method (AS2Sender Component)

A convenient way to set AS2 communication parameters using XML strings.

Syntax

procedure SetTPInfo(Profile: String);

Remarks

SetTPInfo offers a convenient way to set AS2 communication parameters using XML strings. The format of the XML is the same as provided by the method GetTPInfo of AS2ProfileMgr.

The "self" information should always precede the partner information as shown below. AS2Sender as2sender = new AS2Sender(); AS2Profilemgr mgr = new AS2Profilemgr(); mgr.DataDir = @"C:\as2data"; as2sender.SetTPInfo(mgr.GetTPInfo("self")); as2sender.SetTPInfo(mgr.GetTPInfo("partnerOrg")); as2sender.EDIFile = @"C:\as2Data.x12"; as2sender.Post();

VerifyReceipt Method (AS2Sender Component)

Verifies an asynchronous MDN receipt.

Syntax

procedure VerifyReceipt();

Remarks

VerifyReceipt verifies the receipt in MDNReceipt against OriginalContentMIC, MessageId and the preferences specified in MDNOptions. The method operates similarly to Post: After the method finishes, the MDNReceipt, ReceiptSigningProtocol, and ReceiptSignerCert properties will be populated with the appropriate values.

The method operates synchronously, and will throw an exception if any errors or warnings occur. Errors might include a failure to decrypt or authenticate the receipt, the absence of an MDN when one was requested, TCP/IP errors, or any errors reported by the server in the MDN. Warnings might include the return of an unsigned receipt when a signed receipt was requested, or other warnings reported by the server in the MDN.

If an exception is thrown the error code will correspond to the severity of the warning or error, allowing client software to determine whether or not to accept the reply. If multiple errors occur, the exception will return a special error code, and the error message will contain a line for each error's code and description; i.e. "423: Failed to authenticate sender". If the error(s) is/are not fatal processing will not be interrupted, and the relevant properties will be populated as normal.

This method should be used to verify receipts received asynchronously; i.e., not in the HTTP reply to a POST. When posting, asynchronous MDN delivery may be requested by setting MDNDeliveryOption.

  LogMessageB: TBytes
) of Object;

property OnLog: TLogEvent read FOnLog write FOnLog;

Remarks

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

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

The LogMessage event parameter holds the raw log data.

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

SetCookie Event (AS2Sender Component)

SSLServerAuthentication Event (AS2Sender Component)

Fired after the server presents its certificate to the client.

Syntax

type TSSLServerAuthenticationEvent = procedure (
  Sender: TObject;
  CertEncoded: String;
  CertEncodedB: TBytes;
  const CertSubject: String;
  const CertIssuer: String;
  const Status: String;
  var Accept: Boolean
) of Object;

property OnSSLServerAuthentication: TSSLServerAuthenticationEvent read FOnSSLServerAuthentication write FOnSSLServerAuthentication;

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").

SSLStatus Event (AS2Sender Component)

Shows the progress of the secure connection.

Syntax

type TSSLStatusEvent = procedure (
  Sender: TObject;
  const Message: String
) of Object;

property OnSSLStatus: TSSLStatusEvent read FOnSSLStatus write FOnSSLStatus;

Remarks

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

StartTransfer Event (AS2Sender Component)

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

Syntax

type TStartTransferEvent = procedure (
  Sender: TObject;
  Direction: Integer
) of Object;

property OnStartTransfer: TStartTransferEvent read FOnStartTransfer write FOnStartTransfer;

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.

Transfer Event (AS2Sender Component)

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

Syntax

type TTransferEvent = procedure (
  Sender: TObject;
  Direction: Integer;
  BytesTransferred: Int64;
  PercentDone: Integer;
  Text: String;
  TextB: TBytes
) of Object;

property OnTransfer: TTransferEvent read FOnTransfer write FOnTransfer;

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.
