AS3Receiver Class

Properties Methods Events Config Settings Errors

The AS3Receiver class is used to process AS3 messages and generate receipts.

Syntax

ipworksedi.as3receiver()

Remarks

The AS3Receiver class allows you to receive AS3 messages over FTP, as specified in [AS3] and RFC 3335. The class can act as a FTP client, decrypt and verify incoming messages, and generate receipts including Message Disposition Notifications (MDNs). The class is designed to interoperate easily with a standard FTP server.

BASIC OPERATION

You should first log in to the FTP server by invoking Logon. If you need to search the FTP server for requests you may set RemotePath, invoke ListDirectory, etc. When you find the desired files you may then download them invoking ReadRequest. Alternatively, if you acquire the AS3 data by other means you may simply set Request.

ReadRequest (or ParseHeaders) will determine information such as AS3From and AS3To, 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 [AS3]. 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 the same FTP connection by invoking SendResponse. If it is necessary to create a new connection or send receipts to a different server you may Logoff and Logon at will.

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 AS3Receiver1.User = "myusername" AS3Receiver1.Password = "mypassword" AS3Receiver1.RemoteHost = "ftp.mytradingpartner.com" AS3Receiver1.Logon() // You may need to search the server for received files at this point AS3Receiver1.ReadRequest("1053-ji094986.as3") // At this point, you should check the values of AS2From and AS2To. AS3Receiver1.Certificate = new Certificate(CertStoreTypes.cstPFXFile, "\\my_server_directory\\my_pfx_file.pfx", "my password", "CN=Me"); AS3Receiver1.SignerCert = (...); AS3Receiver1.LogDirectory = "c:\\my_server_directory\\my_log_directory"; AS3Receiver1.ProcessRequest(); // It will probably be necessary to change the RemotePath or even logon // to a different server here. AS3Receiver1.SendResponse("1053-ji094986-mdn.as3"); 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.

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

AS3Receiver.Certificate Property

The decryption and receipt signing certificate.

Syntax


 getCertificate(): Certificate;

 setCertificate(certificate: Certificate): void;

Default Value

Remarks

The digital certificate that the class 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.

AS3Receiver.CompressionFormat Property

The compression format used on the incoming message.

Syntax


 getCompressionFormat(): As3receiverCompressionFormats;



enum As3receiverCompressionFormats {
  cfNone,
  cfZLIB
}

Default Value

Remarks

This property is read-only.

AS3Receiver.Connected Property

This shows whether the class is connected.

Syntax


 isConnected(): boolean;

Default Value

FALSE

Remarks

This property is used to determine whether or not the class is connected to the remote host.

Note: It is recommended to use the Connect or Disconnect method instead of setting this property.

This property is not available at design time.

AS3Receiver.EDIData Property

The EDI data sent in Request .

Syntax


 getEDIData(): EDIData;

Default Value

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.

A set of properties related to firewall access.

Syntax


 getFirewall(): Firewall;

 setFirewall(firewall: Firewall): void;

Default Value

Remarks

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

AS3Receiver.FTPLastReply Property

The last reply from the FTP server.

Syntax


 getFTPLastReply(): string;

Default Value

Remarks

The last reply from the FTP server.

This property is read-only.

AS3Receiver.LocalHost Property

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

Syntax


 getLocalHost(): string;

 setLocalHost(localHost: string): void;

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.

AS3Receiver.LogDirectory Property

The path to a directory for logging.

Syntax


 getLogDirectory(): string;

 setLogDirectory(logDirectory: string): void;

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 original EDI data, the complete text of the outgoing request and the incoming response.

The class 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 AS3 messages created or downloaded by the class will be written with extension ".as3", and MDNs created or downloaded will be written with extension ".as3-mdn".

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 ".log" or ".err".

If logs cannot be written an exception will be thrown.

AS3Receiver.LogFile Property

The log file written.

Syntax


 getLogFile(): 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 AS3 messages and MDNs will also be written with extensions ".as3" and ".as3-mdn".

This property is read-only.

AS3Receiver.MDNReceipt Property

The MDN-based receipt generated by the class.

Syntax


 getMDNReceipt(): MDNReceipt;

 setMDNReceipt(MDNReceipt: MDNReceipt): void;

Default Value

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.

AS3Receiver.MDNTo Property

The URL for the Message Disposition Notification (MDN).

Syntax


 getMDNTo(): string;

 setMDNTo(MDNTo: string): void;

Default Value

Remarks

MDNTo corresponds to the Disposition-Notification-To header of RequestHeaders. If nonempty, the client has requested that an MDN-based receipt be returned to the URL specified. This receipt will be generated in a call to ProcessRequest or CreateMDNReceipt, and may be sent by calling SendResponse.

The receipt and headers will be contained in MDNReceipt.

According to RFC specifications, MDNReceipt must be sent if requested by the client.

AS3Receiver.MessageId Property

The message ID of the incoming message.

Syntax


 getMessageId(): 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.

AS3Receiver.Passive Property

This controls whether or not to direct the server into a passive mode. It is recommended if behind a firewall.

Syntax


 isPassive(): boolean;

 setPassive(passive: boolean): void;

Default Value

TRUE

Remarks

This property controls whether or not to direct the server into a passive mode. Many firewalls will not allow the FTP server to open a connection from outside to the higher ports where the FTP client class expects them to be. If Passive is set to TRUE, the class will use the PASV command instead of the PORT command and thus will direct the server into a passive mode: connections are initiated only by the client.

AS3Receiver.Password Property

This is the password used to log in.

Syntax


 getPassword(): string;

 setPassword(password: string): void;

Default Value

Remarks

This property contains the password used to log in. It must be set before the class connects to the FTP server.

AS3Receiver.RemoteHost Property

This is the domain name or IP address of the FTP server.

Syntax


 getRemoteHost(): string;

 setRemoteHost(remoteHost: string): void;

Default Value

Remarks

This property specifies the IP address (IP number in dotted internet format) or the domain name of the FTP server. It is set before a connection is attempted and cannot be changed once a connection is in progress.

If this property is set to a domain name, a DNS request is initiated and upon successful termination of the request, this property is set to the corresponding address. If the search is not successful, an error is returned.

If the class is configured to use a SOCKS firewall, the value assigned to this property may be preceded with an "*". If this is the case, the host name is passed to the firewall unresolved and the firewall performs the DNS resolution.

AS3Receiver.RemotePort Property

This is the port for the FTP service (default is 21).

Syntax


 getRemotePort(): number;

 setRemotePort(remotePort: number): void;

Default Value

Remarks

This property contains the port for the FTP service, which defaults to 21 if not set. A valid port number (a value between 1 and 65535) is required for the connection to take place. The property must be set before a connection is attempted and cannot be changed once a connection is established. Any attempt to change this property while connected will fail with an error.

For an implicit Secure Sockets Layer (SSL), use port 990 (please see the SSLStartMode property for more information).

This property is not available at design time.

AS3Receiver.Request Property

The AS3 request to process.

Syntax


 getRequest(): Uint8Array;

 setRequest(request: Uint8Array): void;

Default Value

Remarks

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

The request may contain the AS3 headers, or these may be specified separately in RequestHeaders. Any methods which read or process the request will split the request into headers and body and populate Request and RequestHeaders appropriately.

AS3Receiver.RequestHeaders Property

The headers in the AS3 request.

Syntax


 getRequestHeaders(): HeaderList;

 setRequestHeaders(requestHeaders: HeaderList): void;

Default Value

Remarks

The headers will be parsed from the request by calls to methods such as ParseHeaders, ParseRequest, or ProcessRequest is invoked.

AS3Receiver.RequestHeadersString Property

The headers in the AS3 request.

Syntax


 getRequestHeadersString(): string;

 setRequestHeadersString(requestHeadersString: string): void;

Default Value

Remarks

The headers will be parsed from the request by calls to methods such as ParseHeaders, ParseRequest, or ProcessRequest is invoked.

AS3Receiver.ScanResult Property

The result of invoking ParseRequest .

Syntax


 getScanResult(): number;

Default Value

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.


0x01	Unable to decrypt data.
0x02	Unable to decompress data.
0x04	Unable to validate integrity of data.
0x08	Unable to verify the signature.
0x10	Client requested unsupported signature type.
0x20	Client requested unsupported MIC algorithm.
0x40	Insufficient message security, as determined by the Config entries RequireSign and RequireEncrypt.
0x80	Unexpected processing error. An exception was encountered outside of message processing, such as configuration issues in the class.
0x100	Duplicate filename.
0x200	Illegal filename.
0x400	Empty filename.
0x800	Error writing incoming file.

This property is read-only.

AS3Receiver.SignerCert Property

Your trading partner's certificate.

Syntax


 getSignerCert(): Certificate;

 setSignerCert(signerCert: Certificate): void;

Default Value

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 class 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.

AS3Receiver.SSLAcceptServerCert Property

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

Syntax


 getSSLAcceptServerCert(): Certificate;

 setSSLAcceptServerCert(SSLAcceptServerCert: Certificate): void;

Default Value

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.

AS3Receiver.SSLCert Property

The certificate to be used during SSL negotiation.

Syntax


 getSSLCert(): Certificate;

 setSSLCert(SSLCert: Certificate): void;

Default Value

Remarks

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

AS3Receiver.SSLProvider Property

This specifies the SSL/TLS implementation to use.

Syntax


 getSSLProvider(): As3receiverSSLProviders;

 setSSLProvider(SSLProvider: As3receiverSSLProviders): void;

enum As3receiverSSLProviders {
  sslpAutomatic,
  sslpPlatform,
  sslpInternal
}

Default Value

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 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:


0 (sslpAutomatic - default)	Automatically selects the appropriate implementation.
1 (sslpPlatform)	Uses the platform/system implementation.
2 (sslpInternal)	Uses the internal implementation.

Additional Notes

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 will be used by default in all cases in the JavaScript edition.

Note: The Internal provider is not support at this time.

AS3Receiver.SSLServerCert Property

The server certificate for the last established connection.

Syntax


 getSSLServerCert(): Certificate;

Default Value

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.

AS3Receiver.SSLStartMode Property

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

Syntax


 getSSLStartMode(): As3receiverSSLStartModes;

 setSSLStartMode(SSLStartMode: As3receiverSSLStartModes): void;

enum As3receiverSSLStartModes {
  sslAutomatic,
  sslImplicit,
  sslExplicit,
  sslNone
}

Default Value

Remarks

The SSLStartMode property may have one of the following values:


0 (sslAutomatic - default)	If the remote port is set to the standard plaintext port of the protocol (where applicable), the class will behave the same as if SSLStartMode is set to sslExplicit. In all other cases, SSL negotiation will be implicit (sslImplicit).
1 (sslImplicit)	The SSL negotiation will start immediately after the connection is established.
2 (sslExplicit)	The class will first connect in plaintext, and then explicitly start SSL negotiation through a protocol command such as STARTTLS.
3 (sslNone)	No SSL negotiation, no SSL security. All communication will be in plaintext mode.

AS3Receiver.Timeout Property

A timeout for the class.

Syntax


 getTimeout(): number;

 setTimeout(timeout: number): void;

Default Value

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 .

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.

AS3Receiver.User Property

This property contains the user identifier to use to log in.

Syntax


 getUser(): string;

 setUser(user: string): void;

Default Value

Remarks

This property contains the user identifier to be used when logging in. It must be set before the class connects to the FTP server.

AS3Receiver.abort Method

The method aborts the current upload or download.

Syntax

async as3receiver.abort(): Promise<void>

Remarks

This method sends an ABOR command to the FTP server. It is used to interrupt file uploads and downloads.

AS3Receiver.changeRemotePath Method

This method changes the current path on the FTP server.

Syntax

async as3receiver.changeRemotePath(remotePath : string): Promise<void>

Remarks

This method changes the current path on the FTP server to the specified RemotePath. When called, the class will issue a command to the server to change the directory. The RemotePath parameter may hold an absolute or relative path.

Absolute Paths

If the path begins with a /, it is considered an absolute path and must specify the entire path from the root of the server. For instance:

component.ChangeRemotePath("/home/testuser/myfolder");

Relative Paths

If the path does not begin with a /, it is considered a relative path and is resolved in relation to the current directory. For instance, a value of myfolder will indicate a subfolder of the current directory. The special value .. refers to the parent directory of the current path. For instance:

//Change to the 'myfolder' sub-directory component.ChangeRemotePath("myfolder"); //Navigate up two levels and then into the 'another/folder' path. component.ChangeRemotePath("../../another/folder");

AS3Receiver.config Method

Sets or retrieves a configuration setting.

Syntax

async as3receiver.config(configurationString : string): Promise<string>

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.

AS3Receiver.createMDNReceipt Method

Creates MDNReceipt .

Syntax

async as3receiver.createMDNReceipt(headers : string, MDN : string, message : string): Promise<void>

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 class 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.

AS3Receiver.deleteFile Method

This method removes a file specified by FileName from an FTP server.

Syntax

async as3receiver.deleteFile(fileName : string): Promise<void>

Remarks

This method is used to remove a file specified by FileName from an FTP server. The remote file or directory specified by FileName is deleted. FileName is either an absolute path on the server, or a path relative to remote path set by ChangeRemotePath. If no FTP session is in place, one is automatically created by first calling the Logon method.

AS3Receiver.getFileSize Method

Gets the size of a file on the FTP server.

Syntax

async as3receiver.getFileSize(fileName : string): Promise<void>

Remarks

Gets the size of the file specified by FileName and RemotePath on the FTP server.

AS3Receiver.getFileTime Method

Gets the last modification time of a file on the FTP server.

Syntax

async as3receiver.getFileTime(fileName : string): Promise<void>

Remarks

Gets the last modification time of the file specified by FileName and RemotePath on the FTP server.

AS3Receiver.listDirectory Method

List the current directory on an FTP server.

Syntax

async as3receiver.listDirectory(filesToList : string): Promise<void>

Remarks

A listing is requested for the directory or file mask specified in FilesToList. This can be an absolute path on the server, a path relative to RemotePath, or a file mask. The file listing is received through the DirList event.

Similar to ListDirectoryLong, except only file names are returned. If no FTP session is in place, one is automatically created by first calling the Logon method.

AS3Receiver.listDirectoryLong Method

List the current directory on an FTP server.

Syntax

async as3receiver.listDirectoryLong(filesToList : string): Promise<void>

Remarks

If no FTP session is in place, one is automatically created by first calling the Logon method.

AS3Receiver.logoff Method

This method is used to log off from the FTP server by posting a QUIT command.

Syntax

async as3receiver.logoff(): Promise<void>

Remarks

This method is used to log off from the FTP server by posting a QUIT command. If that fails, the connection is terminated by the local host.

AS3Receiver.logon Method

Logon to the FTP RemoteHost using the current User and Password .

Syntax

async as3receiver.logon(): Promise<void>

Remarks

Logon to the FTP server using the current User and Password. If an SSL (TLS) connection is required, you should first set SSLStartMode.

Example (Logging On)

FTPControl.RemoteHost = "ftpserver" FTPControl.User = "username" FTPControl.Password = "password" FTPControl.Logon()

AS3Receiver.parseRequest Method

Parses the EDI message and determines the EDIData .

Syntax

async as3receiver.parseRequest(): Promise<void>

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 class 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.

AS3Receiver.processRequest Method

Processes the EDI data, and generates the receipt.

Syntax

async as3receiver.processRequest(): Promise<void>

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

AS3Receiver.readRequest Method

Reads the AS3 request from the FTP server.

Syntax

async as3receiver.readRequest(filename : string): Promise<void>

Remarks

Reads the AS3 request from the FTP server. The name of the file should be given by Filename. The request will be parsed into Request and RequestHeaders. The headers will also be parsed and the following properties will be populated:

AS2From
AS2To
AS2Version
MessageId
MDNTo
ReceiptDeliveryOption
RequestedSignatureProtocol
RequestedMICAlgorithms

ParseRequest may be used to scan the entire message.

AS3Receiver.reset Method

Resets the state of the control.

Syntax

async as3receiver.reset(): Promise<void>

Remarks

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

AS3Receiver.sendResponse Method

Uploads the MDN receipt.

Syntax

async as3receiver.sendResponse(filename : string): Promise<void>

Remarks

Uploads the MDN receipt specified by MDNReceipt. You may create this receipt by invoking ProcessRequest or CreateMDNReceipt.

Prior to sending, you may Logon to the FTP server and navigate to the desired RemotePath. If you have not created an FTP connection already then SendResponse will attempt to establish one.

The URL for upload will be specified (by the sender) in MDNTo.

Filename should contain the name of the file that will be written on the AS3/FTP server.

AS3Receiver.ConnectionStatus Event

This event is fired to indicate changes in the connection state.

Syntax

as3receiver.on('ConnectionStatus', listener: (e: {readonly connectionEvent: string, readonly statusCode: number, readonly description: string}) => void )

Remarks

The Message parameter contains the full text of the message. The Direction parameter shows the originator of the message:


0 (Client)	The `Message` originates from the client.
1 (Server)	The `Message` originates from the server.
2 (Info)	The `Message` is an informative message originating from the client software (the class code).

AS3Receiver.SignerCertInfo Event

This event is fired during verification of the signed message.

Syntax

as3receiver.on('SignerCertInfo', listener: (e: {readonly issuer: string, readonly serialNumber: string, readonly subjectKeyIdentifier: string, readonly certEncoded: string, readonly certEncodedB: Uint8Array}) => void )

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.

AS3Receiver.SSLServerAuthentication Event

Fired after the server presents its certificate to the client.

Syntax

as3receiver.on('SSLServerAuthentication', listener: (e: {readonly certEncoded: string, readonly certEncodedB: Uint8Array, readonly certSubject: string, readonly certIssuer: string, readonly status: string, accept: boolean}) => void )

Remarks

This event fires with information about the server certificate. The Status property shows why verification failed (otherwise, Status contains the string "OK"). To manually accept an untrusted certificate, the SSLAcceptAnyServerCert setting must be set to True before intiating the connection.

AS3Receiver.SSLStatus Event

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 . This can be either a complete or a substring match of the X509 certificate's subject Distinguished Name (DN).

Config Settings (class ipworksedi.as3receiver)

The class accepts one or more of the following configuration settings. Configuration 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.

AS3Receiver Config Settings

LogFilename: The base name of the log file.

If set, this will be used as for the filename of the log file.

Note that only the base name should be specified as the component will append the appropriate file extension.

FTP Config Settings

ActiveModeIP: Allows the specification of the IP address that the server will connect to for active mode connections.

The ActiveModeIP configuration setting can be used to specify the IP address that the server will connect to when using an active mode configuration (Passive = False). When this configuration setting is set, the port number where the component listens for active mode connections will still be managed by the component. The PortRange also can be used to ensure that the correct port is used by the client.

Note: This configuration setting will be ignored if ActiveModePORTAddress is also specified.

ActiveModePORTAddress: Allows the specification of the PORT address value for active mode connections.

When using an active mode configuration (Passive = False) with a firewall, it may be necessary to specify the actual PORT value to be sent to the server. ActiveModePORTAddress takes the protocol-level parameter in the form "a,b,c,d,e,f" where "a,b,c,d" is the external IP address separated by commas, and e and f represent, respectively, the high-byte (divide by 256) and the low-byte (mod 256) values of the external port where the FTP client is listening.

This configuration setting must be used in conjunction with PortRange to ensure that the correct port is used by the client.

AppendToLocalFile: Append downloaded files to a local file.

If set to True, the downloaded files will be appended to the file specified in LocalFile.

ApplyFileMaskLocally: Whether to filter the directory listing locally or on the server.

If set to true any filemask provided to RemoteFile will be applied locally, after the server has returned the results. When set to false (default), the value in RemoteFile will be sent to the server as part of the relevant listing command. Because using filemasks with list commands is not standardized, some servers do not support them and will return an error.

AutoSelectDataIP: Automatically select the data connection IP.

This setting controls the selection logic of the data connection. By default, this value is True and the class will attempt to determine the best IP for the data connection based on the returned value from the server. It is recommended to leave this value set to True unless there is a reason to disable it.

In many cases, FTP servers are not configured to return a valid public IP in the PASV response. When Secure Sockets Layer/Transport Layer Security (SSL/TLS) is used any network address translation (NAT) done by the firewall cannot occur. The result is the client may receive an IP that is not accessible.

This setting is designed to allow the connection to succeed in as many cases as possible. When the IP for the data connection is received from the server, the class will inspect the value. If the received value is not within the known private IP ranges, the class will use it, assuming it is a valid public IP. If the received value is a private IP, the class will instead assume the data connection should be established to the same IP as the command connection (true in almost all cases).

When this setting is False, the class will not perform any checks on the received value. When set to False, UseRemoteHostAddressForPassive is applicable.

CalculatePercentDone: Enables or Disables calculating the percent complete for downloads.

When set to true (default), the class sends an FTP SIZE command to retrieve the file size before beginning a download. When downloading a large quantity of small files, performance may be increased by disabling this feature.

CheckTotalEntry: Whether to ignore directory listing total lines.

Some servers will include "total" information when returning a directory listing that contains non-entry data. When CheckTotalEntry is set to True (default), the component will ignore lines beginning with "total" to account for this. In some cases, it may be desirable to include these lines in the resulting DirList data; this can be done by setting this configuration setting to False.

DILinger: When set to True, DI connections are terminated gracefully.

This property controls how the DI connection is closed. The default is True.

In the case that DILinger is True (default), follow two scenarios to determine how long the connection will linger. In the first scenario, if DILingerTime is 0 (default), the system will attempt to send pending data for a connection until the default IP timeout expires.

In the second scenario, DILingerTime is a positive value, the system will attempt to send pending data until the specified DILingerTime is reached. If this attempt fails, then the system will reset the connection.

The default behavior (which is also the default mode for stream sockets) might result in a long delay in closing the connection. Although the class returns control immediately, the system could hold system resources until all pending data are sent (even after your application closes).

Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (by a client acknowledgment, for example), setting this property to False might be the appropriate course of action.

DILingerTime: Time in seconds to have the DI connection linger.

LingerTime is the time, in seconds, to let the socket connection linger. This value is 0 by default, which means it will use the default IP timeout.

FileTimeFormat: The format of file time reported by the server.

The default value is "M/d/yyyy hh:mm:ss tt". When set, the class will format the time returned by the server when calling the QueryFileTime method. To disable all formatting, set this to empty string.

Note: This setting applies only when calling QueryFileTime. It does not apply to the FileTime parameter of the DirList event.

IgnoreEntries: Directory entry data to ignore.

Sometimes the FTP server will return data in a directory listing that is not entry data and can be ignored. The IgnoreEntries configuration setting takes a comma-separated list of entries to ignore. Only the beginning of the entries need to be specified and correct case is not required.

MaskSensitive: Masks passwords in logs.

The default value is False. When set to True, the class will mask passwords that otherwise would appear in its logs.

ModeZCompressionLevel: Used to specify the level of compression used.

The default value is 7. Valid values range from 0 to 9. A higher value indicates that a higher compression level is being used. This is valid only when UseModeZ is set to True.

Note: When this setting is specified the class immediately performs an action. Use the ConfigAsync method in order to avoid blocking execution.

PortRange: Allows the specification of a port range where the class listens for active mode connections.

When set to use active mode (Passive = False), the class uses any available port to listen to incoming connections from the server. You can override this behavior by setting PortRange to a value containing the range of ports the class will be listening to.

The range is provided as start-end, for instance: "1024-" stands for anything higher than 1024, "1024-2048" stands for ports between 1024 and 2048 inclusive, "4000-4010, 50000-50010" stands for ports between 4000 and 4010 or between 50000 and 50010.

PreserveFileTime: Attempts to preserve timestamps when transferring files.

When set to True, the class will try to preserve timestamps when transferring files. The MDTM command is used when downloading, and the MFTM command is used when uploading. The server must support these commands for this to work and is False by default.

RealTimeUpload: Enables real time uploading.

When this value is set to True, the class will upload the data in the file specified by LocalFile and continue monitoring LocalFile for additional data to upload until no new data is found for RealTimeUploadAgeLimit seconds. This allows you to start uploading a file immediately after the file is created and continue uploading as data is written to the file. The default value is False.

RealTimeUploadAgeLimit: The age limit in seconds when using RealTimeUpload.

This value is only applicable when RealTimeUpload is set to "True". This specifies the number of seconds for which the class will monitor LocalFile for new data to upload. If this limit is reached and no new data are found in LocalFile the upload will complete. The default value is "1".

ReusePISSLSessionInDI: Whether the PI SSL session will be reused for the DI connection.

When set to True (default), the class will reuse the PI SSL session when creating the DI connection. When set to False, the class will create a separate SSL session for the DI connection. The default value is True.

ReuseSSLSessionInDI: Whether the SSL session will be reused for the DI connection.

When set to True (default), the class will ask the server to reuse the existing DI Secure Sockets Layer (SSL) session. When set to False, a new SSL session will always be created for the DI connection.

UseClearChannel: Allows for the Clear Command Channel (CCC) command.

When this is set, the class will send the CCC command to the server requesting a clear (unprotected) command channel.

UseClearDataChannel: Allows for the PROT C command.

When this is set, the class will use a clear (unprotected) data channel by sending the PROT C command to the server.

UseEPSV: Allows extended passive mode.

When this is set, the extended passive mode will be used.

UseMLSD: Uses listings for machine processing.

When this is set to True, the class will list files in the directory using the MLSD command. This command is an extension to the protocol that defines a more standardized and reliable directory listing format. Not all servers support this command. The default value is False.

When set to True, set RemoteFile to the filemask and call either ListDirectory or ListDirectoryLong. There is no difference between the two methods when this setting is enabled.

UseMLST: Uses single file listing for machine processing.

This setting is similar to UseMLSD except that it is valid only for a single file. When this is set to True, the class will list the file or folder specified by RemoteFile. If RemoteFile is not set, a listing for the current directory will be returned. This command is an extension to the protocol, which defines a more standardized and reliable directory listing format, but does so only for a single file or folder. Not all servers support this command. The default value is False.

When set to True, set RemoteFile to the file or folder you wish to get information about and call either ListDirectory or ListDirectoryLong. There is no difference between the two methods when this setting is enabled. When both UseMLSD and UseMLST are set, UseMLSD takes precedence.

UseModeZ: Allows compression to be used when transferring data.

The default value is False. When set to True, the class will issue the MODE Z command to the FTP server. This will enable deflate compression so that all data transferred are first compressed either by the server (when downloading) or by the class (when uploading). Note: Not all servers support this feature.

Note: When this setting is specified the class immediately performs an action. Use the ConfigAsync method in order to avoid blocking execution.

UseOldAUTHSSL: Allows use of the 'AUTH SSL' command instead of 'AUTH TLS'.

By default, the class uses the standard AUTH TLS command to initiate the SSL handshake with the server. This configuration setting is included for optional support of older servers that support only the AUTH SSL command.

Note: Using AUTH SSL instead of AUTH TLS is strongly discouraged because of potential security vulnerabilities. If you must use this configuration setting, please do so very carefully.

UseProtWhenImplicit: Sends the PROT P command to the server.

When SSLStartMode is set to sslImplicit, setting this to True will instruct the class to send the PROT P command to the server. This explicitly tells the server that the data channel will be protected. The default value is True.

UseRemoteHostAddressForPassive: Instructs the class to use the address specified by RemoteHost when establishing a data connection.

When this setting is True, the class will use the address specified by RemoteHost when establishing a data connection for directory listings and file transfers. This setting is applicable only when AutoSelectDataIP is set to False.

When this setting is False (default) and AutoSelectDataIP is also False, the class will use the IP address returned by the server when establishing a data connection.

This setting is not applicable when Passive is set to False (Active mode).

VirtualHostName: Sends the HOST command to the server.

Defined in RFC 7151, the HOST command allows user-FTP processes to specify which virtual host to connect to for a server-FTP process that is handling requests for multiple virtual hosts on a single IP address. When this configuration setting is set, the HOST command is sent to the server before authenticating.

TCPClient Config Settings

ConnectionTimeout: Sets a separate timeout value for establishing a connection.

When set, this configuration setting allows you to specify a different timeout value for establishing a connection. Otherwise, the class will use Timeout for establishing a connection and transmitting/receiving data.

FirewallAutoDetect: Tells the class whether or not to automatically detect and use firewall system settings, if available.

This configuration setting is provided for use by classs that do not directly expose Firewall properties.

FirewallHost: Name or IP address of firewall (optional).

If a FirewallHost is given, requested connections will be authenticated through the specified firewall when connecting.

If the FirewallHost setting is set to a Domain Name, a DNS request is initiated. Upon successful termination of the request, the FirewallHost setting is set to the corresponding address. If the search is not successful, an error is returned.

Note: This setting is provided for use by classs that do not directly expose Firewall properties.

FirewallPassword: Password to be used if authentication is to be used when connecting through the firewall.

If FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the given firewall. If the authentication fails, the class .

Note: This setting is provided for use by classs that do not directly expose Firewall properties.

FirewallPort: The TCP port for the FirewallHost;.

The FirewallPort is set automatically when FirewallType is set to a valid value.

Note: This configuration setting is provided for use by classs that do not directly expose Firewall properties.

FirewallType: Determines the type of firewall to connect through.

The appropriate values are as follows:


0	No firewall (default setting).
1	Connect through a tunneling proxy. FirewallPort is set to 80.
2	Connect through a SOCKS4 Proxy. FirewallPort is set to 1080.
3	Connect through a SOCKS5 Proxy. FirewallPort is set to 1080.
10	Connect through a SOCKS4A Proxy. FirewallPort is set to 1080.

Note: This setting is provided for use by classs that do not directly expose Firewall properties.

FirewallUser: A user name if authentication is to be used connecting through a firewall.

If the FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the Firewall. If the authentication fails, the class .

Note: This setting is provided for use by classs that do not directly expose Firewall properties.

KeepAliveInterval: The retry interval, in milliseconds, to be used when a TCP keep-alive packet is sent and no response is received.

When set, TCPKeepAlive will automatically be set to True. A TCP keep-alive packet will be sent after a period of inactivity as defined by KeepAliveTime. If no acknowledgment is received from the remote host, the keep-alive packet will be sent again. This configuration setting specifies the interval at which the successive keep-alive packets are sent in milliseconds. This system default if this value is not specified here is 1 second.

Note: This value is not applicable in macOS.

KeepAliveTime: The inactivity time in milliseconds before a TCP keep-alive packet is sent.

When set, TCPKeepAlive will automatically be set to True. By default, the operating system will determine the time a connection is idle before a Transmission Control Protocol (TCP) keep-alive packet is sent. This system default if this value is not specified here is 2 hours. In many cases, a shorter interval is more useful. Set this value to the desired interval in milliseconds.

Linger: When set to True, connections are terminated gracefully.

This property controls how a connection is closed. The default is True.

In the case that Linger is True (default), two scenarios determine how long the connection will linger. In the first, if LingerTime is 0 (default), the system will attempt to send pending data for a connection until the default IP timeout expires.

In the second scenario, if LingerTime is a positive value, the system will attempt to send pending data until the specified LingerTime is reached. If this attempt fails, then the system will reset the connection.

Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (e.g., by a client acknowledgment), setting this property to False might be the appropriate course of action.

LingerTime: Time in seconds to have the connection linger.

LingerTime is the time, in seconds, the socket connection will linger. This value is 0 by default, which means it will use the default IP timeout.

LocalHost: The name of the local host through which connections are initiated or accepted.

The LocalHost setting 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.

If the class is connected, the LocalHost setting 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).

LocalPort: The port in the local host where the class binds.

This must be set before a connection is attempted. It instructs the class to bind to a specific port (or communication endpoint) in the local machine.

Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by LocalPort after the connection is established.

LocalPort cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error.

This; setting is useful when trying to connect to services that require a trusted port in the client side. An example is the remote shell (rsh) service in UNIX systems.

MaxLineLength: The maximum amount of data to accumulate when no EOL is found.

MaxLineLength is the size of an internal buffer, which holds received data while waiting for an EOL string.

If an EOL string is found in the input stream before MaxLineLength bytes are received, the DataIn event is fired with the EOL parameter set to True, and the buffer is reset.

If no EOL is found, and MaxLineLength bytes are accumulated in the buffer, the DataIn event is fired with the EOL parameter set to False, and the buffer is reset.

The minimum value for MaxLineLength is 256 bytes. The default value is 2048 bytes.

MaxTransferRate: The transfer rate limit in bytes per second.

This configuration setting can be used to throttle outbound TCP traffic. Set this to the number of bytes to be sent per second. By default, this is not set and there is no limit.

ProxyExceptionsList: A semicolon separated list of hosts and IPs to bypass when using a proxy.

This configuration setting optionally specifies a semicolon-separated list of hostnames or IP addresses to bypass when a proxy is in use. When requests are made to hosts specified in this property, the proxy will not be used. For instance:

www.google.com;www.nsoftware.com

TCPKeepAlive: Determines whether or not the keep alive socket option is enabled.

If set to True, the socket's keep-alive option is enabled and keep-alive packets will be sent periodically to maintain the connection. Set KeepAliveTime and KeepAliveInterval to configure the timing of the keep-alive packets.

Note: This value is not applicable in Java.

TcpNoDelay: Whether or not to delay when sending packets.

When true, the socket will send all data that is ready to send at once. When false, the socket will send smaller buffered packets of data at small intervals. This is known as the Nagle algorithm.

By default, this config is set to false.

UseIPv6: Whether to use IPv6.

When set to 0 (default), the class will use IPv4 exclusively. When set to 1, the class will use IPv6 exclusively. To instruct the class to prefer IPv6 addresses, but use IPv4 if IPv6 is not supported on the system, this setting should be set to 2. The default value is 0. Possible values are:


0	IPv4 Only
1	IPv6 Only
2	IPv6 with IPv4 fallback

SSL Config Settings

LogSSLPackets: Controls whether SSL packets are logged when using the internal security API.

When SSLProvider is set to Internal, this setting controls whether SSL packets should be logged. By default, this setting is False, as it is only useful for debugging purposes.

When enabled, SSL packet logs are output using the SSLStatus event, which will fire each time an SSL packet is sent or received.

Enabling this setting has no effect if SSLProvider is set to Platform.

OpenSSLCADir: The path to a directory containing CA certificates.

This functionality is available only when the provider is OpenSSL.

The path set by this property should point to a directory containing CA certificates in PEM format. The files each contain one CA certificate. The files are looked up by the CA subject name hash value, which must hence be available. If more than one CA certificate with the same name hash value exist, the extension must be different (e.g. 9d66eef0.0, 9d66eef0.1 etc). OpenSSL recommends to use the c_rehash utility to create the necessary links. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.

OpenSSLCAFile: Name of the file containing the list of CA's trusted by your application.

This functionality is available only when the provider is OpenSSL.

The file set by this property should contain a list of CA certificates in PEM format. The file can contain several CA certificates identified by

-----BEGIN CERTIFICATE-----

... (CA certificate in base64 encoding) ...

-----END CERTIFICATE-----

sequences. Before, between, and after the certificates text is allowed which can be used e.g. for descriptions of the certificates. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.

OpenSSLCipherList: A string that controls the ciphers to be used by SSL.

This functionality is available only when the provider is OpenSSL.

The format of this string is described in the OpenSSL man page ciphers(1) section "CIPHER LIST FORMAT". Please refer to it for details. The default string "DEFAULT" is determined at compile time and is normally equivalent to "ALL:!ADH:RC4+RSA:+SSLv2:@STRENGTH".

OpenSSLPrngSeedData: The data to seed the pseudo random number generator (PRNG).

This functionality is available only when the provider is OpenSSL.

By default OpenSSL uses the device file "/dev/urandom" to seed the PRNG and setting OpenSSLPrngSeedData is not required. If set, the string specified is used to seed the PRNG.

ReuseSSLSession: Determines if the SSL session is reused.

If set to true, the class will reuse the context if and only if the following criteria are met:

The target host name is the same.
The system cache entry has not expired (default timeout is 10 hours).
The application process that calls the function is the same.
The logon session is the same.
The instance of the class is the same.

SSLAcceptAnyServerCert: Whether to trust any certificate presented by the server.

This setting disables all certificate verification when set to True. This configuration setting must be enabled to trust a self-signed certificate. It is not recommended to enable this configuration setting in a production environment. The default value is False.

SSLCACerts: A newline separated list of CA certificate to use during SSL client authentication.

This setting specifies one or more CA certificates to be included in the request when performing SSL client authentication. Some servers require the entire chain, including CA certificates, to be presented when performing SSL client authentication. The value of this setting is a newline (CrLf) separated list of certificates. For instance:

-----BEGIN CERTIFICATE-----

-----END CERTIFICATE-----

SSLCipherStrength: The minimum cipher strength used for bulk encryption.

This minimum cipher strength largely dependent on the security modules installed on the system. If the cipher strength specified is not supported, an error will be returned when connections are initiated.

Please note that this setting contains the minimum cipher strength requested from the security library. The actual cipher strength used for the connection is shown by the SSLStatus event.

Use this setting with caution. Requesting a lower cipher strength than necessary could potentially cause serious security vulnerabilities in your application.

When the provider is OpenSSL, SSLCipherStrength is currently not supported. This functionality is instead made available through the OpenSSLCipherList config setting.

SSLEnabledCipherSuites: The cipher suite to be used in an SSL negotiation.

The enabled cipher suites to be used in SSL negotiation.

By default, the enabled cipher suites will include all available ciphers ("*").

The special value "*" means that the class will pick all of the supported cipher suites. If SSLEnabledCipherSuites is set to any other value, only the specified cipher suites will be considered.

Multiple cipher suites are separated by semicolons.

Example values when SSLProvider is set to Platform: obj.config("SSLEnabledCipherSuites=*"); obj.config("SSLEnabledCipherSuites=CALG_AES_256"); obj.config("SSLEnabledCipherSuites=CALG_AES_256;CALG_3DES"); Possible values when SSLProvider is set to Platform include:

When TLS 1.3 is negotiated (see SSLEnabledProtocols) only the following cipher suites are supported:

TLS_AES_256_GCM_SHA384
TLS_CHACHA20_POLY1305_SHA256
TLS_AES_128_GCM_SHA256

SSLEnabledCipherSuites is used together with SSLCipherStrength.

SSLEnabledProtocols: Used to enable/disable the supported security protocols.

Used to enable/disable the supported security protocols.

Not all supported protocols are enabled by default (the value of this setting is 4032). If you want more granular control over the enabled protocols, you can set this property to the binary 'OR' of one or more of the following values:


TLS1.3	12288 (Hex 3000)
TLS1.2	3072 (Hex C00) (Default)
TLS1.1	768 (Hex 300) (Default)
TLS1	192 (Hex C0) (Default)
SSL3	48 (Hex 30)
SSL2	12 (Hex 0C)

SSLEnabledProtocols - TLS 1.3 Notes

In the JavaScript edition the platform implementation is used when TLS 1.3 is enabled and SSLEnabledCipherSuites and other similar SSL configuration settings are not supported.

SSLEnableRenegotiation: Whether the renegotiation_info SSL extension is supported.

This setting specifies whether the renegotiation_info SSL extension will be used in the request when using the internal security API. This setting is true by default, but can be set to false to disable the extension.

This setting is only applicable when SSLProvider is set to Internal.

SSLIncludeCertChain: Whether the entire certificate chain is included in the SSLServerAuthentication event.

This setting specifies whether the Encoded parameter of the SSLServerAuthentication event contains the full certificate chain. By default this value is False and only the leaf certificate will be present in the Encoded parameter of the SSLServerAuthentication event.

If set to True all certificates returned by the server will be present in the Encoded parameter of the SSLServerAuthentication event. This includes the leaf certificate, any intermediate certificate, and the root certificate.

SSLKeyLogFile: The location of a file where per-session secrets are written for debugging purposes.

This setting optionally specifies the full path to a file on disk where per-session secrets are stored for debugging purposes.

When set, the class will save the session secrets in the same format as the SSLKEYLOGFILE environment variable functionality used by most major browsers and tools such as Chrome, Firefox, and cURL. This file can then be used in tools such as Wireshark to decrypt TLS traffice for debugging purposes. When writing to this file the class will only append, it will not overwrite previous values.

Note: This setting is only applicable when SSLProvider is set to Internal.

SSLNegotiatedCipher: Returns the negotiated ciphersuite.

Returns the ciphersuite negotiated during the SSL handshake.

Note: For server components (e.g. TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedCipher[connId]");

SSLNegotiatedCipherStrength: Returns the negotiated ciphersuite strength.

Returns the strength of the ciphersuite negotiated during the SSL handshake.

Note: For server components (e.g.TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedCipherStrength[connId]");

SSLNegotiatedCipherSuite: Returns the negotiated ciphersuite.

Returns the ciphersuite negotiated during the SSL handshake represented as a single string.

Note: For server components (e.g. TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedCipherSuite[connId]");

SSLNegotiatedKeyExchange: Returns the negotiated key exchange algorithm.

Returns the key exchange algorithm negotiated during the SSL handshake.

Note: For server components (e.g. TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedKeyExchange[connId]");

SSLNegotiatedKeyExchangeStrength: Returns the negotiated key exchange algorithm strength.

Returns the strenghth of the key exchange algorithm negotiated during the SSL handshake.

Note: For server components (e.g. TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedKeyExchangeStrength[connId]");

SSLNegotiatedVersion: Returns the negotiated protocol version.

Returns the protocol version negotiated during the SSL handshake.

Note: For server components (e.g. TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedVersion[connId]");

SSLSecurityFlags: Flags that control certificate verification.

The following flags are defined (specified in hexadecimal notation). They can be or-ed together to exclude multiple conditions:


0x00000001	Ignore time validity status of certificate.
0x00000002	Ignore time validity status of CTL.
0x00000004	Ignore non-nested certificate times.
0x00000010	Allow unknown Certificate Authority.
0x00000020	Ignore wrong certificate usage.
0x00000100	Ignore unknown certificate revocation status.
0x00000200	Ignore unknown CTL signer revocation status.
0x00000400	Ignore unknown Certificate Authority revocation status.
0x00000800	Ignore unknown Root revocation status.
0x00008000	Allow test Root certificate.
0x00004000	Trust test Root certificate.
0x80000000	Ignore non-matching CN (certificate CN not-matching server name).

This functionality is currently not available when the provider is OpenSSL.

SSLServerCACerts: A newline separated list of CA certificate to use during SSL server certificate validation.

This setting optionally specifies one or more CA certificates to be used when verifying the server certificate. When verifying the server's certificate the certificates trusted by the system will be used as part of the verification process. If the server's CA certificates are not installed to the trusted system store, they may be specified here so they are included when performing the verification process. This setting should only be set if the server's CA certificates are not already trusted on the system and cannot be installed to the trusted system store.

The value of this setting is a newline (CrLf) separated list of certificates. For instance:

-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw

-----END CERTIFICATE-----

TLS12SignatureAlgorithms: Defines the allowed TLS 1.2 signature algorithms when SSLProvider is set to Internal.

This setting specifies the allowed server certificate signature algorithms when SSLProvider is set to Internal and SSLEnabledProtocols is set to allow TLS 1.2.

When specified the class will verify that the server certificate signature algorithm is among the values specified in this setting. If the server certificate signature algorithm is unsupported the class .

The format of this value is a comma separated list of hash-signature combinations. For instance: component.SSLProvider = TCPClientSSLProviders.sslpInternal; component.Config("SSLEnabledProtocols=3072"); //TLS 1.2 component.Config("TLS12SignatureAlgorithms=sha256-rsa,sha256-dsa,sha1-rsa,sha1-dsa"); The default value for this setting is sha512-ecdsa,sha512-rsa,sha512-dsa,sha384-ecdsa,sha384-rsa,sha384-dsa,sha256-ecdsa,sha256-rsa,sha256-dsa,sha224-ecdsa,sha224-rsa,sha224-dsa,sha1-ecdsa,sha1-rsa,sha1-dsa.

In order to not restrict the server's certificate signature algorithm, specify an empty string as the value for this setting, which will cause the signature_algorithms TLS 1.2 extension to not be sent.

TLS12SupportedGroups: The supported groups for ECC.

This setting specifies a comma separated list of named groups used in TLS 1.2 for ECC.

The default value is ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1.

When using TLS 1.2 and SSLProvider is set to Internal, the values refer to the supported groups for ECC. The following values are supported:

"ecdhe_secp256r1" (default)
"ecdhe_secp384r1" (default)
"ecdhe_secp521r1" (default)

TLS13KeyShareGroups: The groups for which to pregenerate key shares.

This setting specifies a comma separated list of named groups used in TLS 1.3 for key exchange. The groups specified here will have key share data pregenerated locally before establishing a connection. This can prevent an additional round trip during the handshake if the group is supported by the server.

The default value is set to balance common supported groups and the computational resources required to generate key shares. As a result only some groups are included by default in this setting.

Note: All supported groups can always be used during the handshake even if not listed here, but if a group is used which is not present in this list it will incur an additional round trip and time to generate the key share for that group.

In most cases this setting does not need to be modified. This should only be modified if there is a specific reason to do so.

The default value is ecdhe_x25519,ecdhe_secp256r1,ecdhe_secp384r1,ffdhe_2048,ffdhe_3072

The values are ordered from most preferred to least preferred. The following values are supported:

"ecdhe_x25519" (default)
"ecdhe_x448"
"ecdhe_secp256r1" (default)
"ecdhe_secp384r1" (default)
"ecdhe_secp521r1"
"ffdhe_2048" (default)
"ffdhe_3072" (default)
"ffdhe_4096"
"ffdhe_6144"
"ffdhe_8192"

TLS13SignatureAlgorithms: The allowed certificate signature algorithms.

This setting holds a comma separated list of allowed signature algorithms. Possible values are:

"ed25519" (default)
"ed448" (default)
"ecdsa_secp256r1_sha256" (default)
"ecdsa_secp384r1_sha384" (default)
"ecdsa_secp521r1_sha512" (default)
"rsa_pkcs1_sha256" (default)
"rsa_pkcs1_sha384" (default)
"rsa_pkcs1_sha512" (default)
"rsa_pss_sha256" (default)
"rsa_pss_sha384" (default)
"rsa_pss_sha512" (default)

The default value is rsa_pss_sha256,rsa_pss_sha384,rsa_pss_sha512,rsa_pkcs1_sha256,rsa_pkcs1_sha384,rsa_pkcs1_sha512,ecdsa_secp256r1_sha256,ecdsa_secp384r1_sha384,ecdsa_secp521r1_sha512,ed25519,ed448. This setting is only applicable when SSLEnabledProtocols includes TLS 1.3.

TLS13SupportedGroups: The supported groups for (EC)DHE key exchange.

This setting specifies a comma separated list of named groups used in TLS 1.3 for key exchange. This setting should only be modified if there is a specific reason to do so.

The default value is ecdhe_x25519,ecdhe_x448,ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1,ffdhe_2048,ffdhe_3072,ffdhe_4096,ffdhe_6144,ffdhe_8192

The values are ordered from most preferred to least preferred. The following values are supported:

"ecdhe_x25519" (default)
"ecdhe_x448" (default)
"ecdhe_secp256r1" (default)
"ecdhe_secp384r1" (default)
"ecdhe_secp521r1" (default)
"ffdhe_2048" (default)
"ffdhe_3072" (default)
"ffdhe_4096" (default)
"ffdhe_6144" (default)
"ffdhe_8192" (default)

Socket Config Settings

AbsoluteTimeout: Determines whether timeouts are inactivity timeouts or absolute timeouts.

If AbsoluteTimeout is set to True, any method which does not complete within Timeout seconds will be aborted. By default, AbsoluteTimeout is False, and the timeout is an inactivity timeout.

Note: This option is not valid for UDP ports.

FirewallData: Used to send extra data to the firewall.

When the firewall is a tunneling proxy, use this property to send custom (additional) headers to the firewall (e.g. headers for custom authentication schemes).

InBufferSize: The size in bytes of the incoming queue of the socket.

This is the size of an internal queue in the TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be receiving. Increasing the value of the InBufferSize setting can provide significant improvements in performance in some cases.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the class is activated the InBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.

OutBufferSize: The size in bytes of the outgoing queue of the socket.

This is the size of an internal queue in the TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be sending. Increasing the value of the OutBufferSize setting can provide significant improvements in performance in some cases.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the class is activated the OutBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.

Base Config Settings

BuildInfo: Information about the product's build.

When queried, this setting will return a string containing information about the product's build.

CodePage: The system code page used for Unicode to Multibyte translations.

The default code page is Unicode UTF-8 (65001).

LicenseInfo: Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a class is using. It will return the following information:

Product: The product the license is for.
Product Key: The key the license was generated from.
License Source: Where the license was found (e.g., RuntimeLicense, License File).
License Type: The type of license installed (e.g., Royalty Free, Single Server).
Last Valid Build: The last valid build number for which the license will work.

MaskSensitive: Whether sensitive data is masked in log messages.

In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to true to mask sensitive data. The default is false.

This setting only works on these classes: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.

UseInternalSecurityAPI: Tells the class whether or not to use the system security libraries or an internal implementation.

When set to false, the class will use the system security libraries by default to perform cryptographic functions where applicable.

Setting this setting to true tells the class to use the internal implementation instead of using the system security libraries.

This setting is set to false by default on all platforms.
