OFTP Adapter

The OFTP Component adds OFTP send and receive capabilities to your BizTalk Server.

Remarks

The OFTP, or Odette File Transfer Protocol, Adapter adds a complete OFTP client to your BizTalk Server that enables it with file download and upload capability.

OFTP Receive Adapter

The OFTP Receive Adapter requires certain server properties be set. You must set the OFTPServer property to the remote location of the desired OFTP server. You may also set an OFTPPort if the server is not set to the default protocol port. For client authorization, you must set the ClientSSIDCode, ClientSFIDCode, and ClientPassword properties. And, for server authentication, you must set the ServerSSIDCode, ServerSFIDCode, and ServerPassword properties.

If you want to use secure authentication with encryption to and from the server, set SecureAuthentication to True, set the Certificate property to a certificate containing your private key, and set the RecipientCert property to the server's public certificate.

The adapter will connect to the OFTP server every PollingInterval and download all files in the server's outgoing queue, and submit these to the BizTalk Message Engine as individual messages.

OFTP Send Adapter

The OFTP Send Adapter also requires certain server properties be set. You must set the OFTPServer property to the remote location of the desired OFTP server. You may also set an OFTPPort if the server is not set to the default protocol port. For client authorization, you must set the ClientSSIDCode, ClientSFIDCode, and ClientPassword properties. And, for server authentication, you must set the ServerSSIDCode, ServerSFIDCode, and ServerPassword properties.

The adapter will connect to the OFTP server whenever it has a message to send and attempt to upload the file to the server. It uses the name specified by VirtualFileName when sending to the server. If this is not specified, the temporary filename will be used.

Please refer to the section on adapter configuration for a description of how to configure receive locations and send ports for this adapter.

OFTP Transmitter

Setting the OFTP Adapter Configuration Properties for a Dynamic Send Port

A dynamic send port does not provide any transport configuration options in BizTalk Explorer because it is expected that these properties will be provided with the context properties associated with the message. These properties can be set in a custom pipeline or in an orchestration. To set message configuration properties in an orchestration you can do the following:

Add a Construct Message shape to your orchestration.
Configure the Construct Message shape to construct a new message. (for example Message_2)
Add a Message Assignment shape to the Construct Message shape.
Add code to the Message Assignment shape to initialize the message that you constructed and to set the appropriate configuration properties for the message.

Certificate Property (OFTP Adapter)

The private key certificate.

Data Type

Certificate

Remarks

Set this property to a valid certificate to perform different operations such as session authentication, signing a file or receipt, or decrypting a file.

This field is used to set a Private Key Certificate.

Private key certificates may be loaded from the registry, from files in PKCS#12 format, or from a PEM file format. If you click on the ellipses, a certificate selection dialog will open. To select a private key from the system registry, select the System Store tab or the User Store tab, and highlight the appropriate registry store. The list of certificates which have private keys will be shown below.

To select a private key certificate from a file in PKCS#12 format, select the PFX Store tab. The browse button can be used to examine the file system for PKCS#12 (.pfx or .p12) certificates. If you wish to examine the certificate, provide the password in the field provided and click on the Open button to examine the file store for certificates present. To load a certificate from PEM files, select the PEM tab. Like the PFX file selection, you can specify the password and click the Open button to examine the certificates in the PEM store, or you may paste any PEM data stored in memory.

Regardless of how you selected the certificate, once you hit the OK button, the adapter will attempt to verify that certificate selection. If successful, the subject of the certificate will be displayed in the property field. If the adapter was not able to verify the selection, a dialog box will appear instead detailing the verification error.

ClientPassword Property (OFTP Adapter)

The client's password.

Data Type

Password

Default Value

Remarks

The password assigned to the client in the bilateral agreement. This property must be a string of no more than 8 characters long.

ClientSFIDCode Property (OFTP Adapter)

Client's SFID code.

Data Type

String

Default Value

Remarks

This code is usually the same as the SSID code specified in the ClientSSIDCode property. However, when a company has more than one entity, they may have a different SFID code for each entity in the company.

ClientSSIDCode Property (OFTP Adapter)

The client's SSID code.

Data Type

String

Default Value

Remarks

The identification code of the client. This code may be less than, but no more than 25 characters long. Generally, SSID codes have the following format as specified in rfc 2204 that is based on ISO 6523:


Code Identifier	'O' - Indicates ODETTE assigned the Organization Identifier. Other values can be used for non-ODETTE codes. NOTE: This field is a fixed length of 1 character.
International Code	A code forming part of the Organization Identifier. NOTE: This field may be of variable length up to 4 characters long.
Organization Code	A code forming part of the Organization Identifier. This field may contain the letters A to Z, the digits 0 to 9, and space and hyphen characters. NOTE: This field may be of variable length up to 14 characters long.
Computer Sub-Address	A locally assigned address which uniquely identifies a system within an organization (defined by an Organization Identifier). NOTE: This field may be of variable length up to 6 characters long.

Compress Property (OFTP Adapter)

Whether or not to compress the outgoing file.

Data Type

Boolean

Default Value

false

Remarks

When sending a file to the trading partner, set this to true for the adapter to compress the file before sending.

The file will first be compressed to a temporary file before being sent. Therefore, the TempPath property is required when compression is being used.

This property is not available in the Receiver.

ConnectionLifetime Property (OFTP Adapter)

Instructs the component whether or not to leave the connection to the server open.

Data Type

Enumeration

Possible Values

Automatic (0)
Per Batch (1)
Persisted (2)

Default Value

Remarks

This property is used when uploading batches of messages to a server that use the same connection properties. In order to minimize connection-related protocol overhead, connections may be persisted with various lifetimes:


Automatic (0 - default)	The connection to the server will be established as needed per each message. When the message transmission is complete, the adapter will disconnect from the server.
Per Batch (1)	During each batch, the connection to the server will be established as needed per each message. If a connection already exists to the server, that will be used as opposed to creating a new one. At the end of the batch, all such connections will be disconnected.
Persisted (2)	Connections will be established as needed and stored. If a connection already exists for a server, that will be used as opposed to creating a new one. The connections will not be disconnected until the adapter is terminated by the BizTalk Message Engine.

This property is not available in the Receiver.

EncryptionAlgorithm Property (OFTP Adapter)

The encryption algorithm.

Data Type

Enumeration

Possible Values

3DES (0)
AES (1)

Default Value

Remarks

In order to use encryption, you must set the VirtualFileSecurityLevel property. The supported algorithms for encryption are:


3DES (0)	Triple Data Encryption Standard.
AES (1)	Advanced Encryption Standard with key length of 128.

This property is not available in the Receiver.

ErrorThreshold Property (OFTP Adapter)

The maximum number of errors before the component shuts down.

Data Type

Integer

Default Value

Remarks

This property limits the number of errors that the adapter can incur before it shuts down and stops processing messages.

If set to 0 the adapter will never shutdown.

Note that if the operation completes successfully the current error count will be reset.

This property may be configured on the adapter's static handler property page in the BizTalk Server administration console.

This property is not available in the Sender.

Firewall Property (OFTP Adapter)

A set of properties related to firewall access.

Data Type

Firewall

Remarks

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

MaxBatchSize Property (OFTP Adapter)

The maximum size, in MB, of the current batch (0 indicates no limit).

Data Type

Integer

Default Value

Remarks

This property limits the maximum amount of data the adapter can store before finalizing and processing the current batch to the number of bytes indicated.

Note: the default value, "0" indicates that there is no limit on the size of the batch. This value is not recommended for production environments as it may result in extremely large batches being held in memory before the adapter moves the data to the next stage of processing.

This property may be configured on the adapter's static handler property page in the BizTalk Server administration console.

This property is not available in the Sender.

MaxFileCount Property (OFTP Adapter)

The maximum number of files in the current batch (0 indicates no limit).

Data Type

Integer

Default Value

Remarks

This property places a limit on the number of files that can be transmitted in a single batch.

This property may be configured on the adapter's static handler property page in the BizTalk Server administration console.

This property is not available in the Sender.

MaxFileSize Property (OFTP Adapter)

The maximum size, in MB, of a file in the current batch (0 indicates no limit).

Data Type

Integer

Default Value

Remarks

This property limits the maximum size of any file in the current transmission batch to the number of bytes indicated.

This property may be configured on the adapter's static handler property page in the BizTalk Server administration console.

This property is not available in the Sender.

MaxPersistentConnections Property (OFTP Adapter)

The maximum number of simultaneous persistent connections when sending.

Data Type

Integer

Default Value

Remarks

This setting specifies the maximum number of simultaneous persistent connections when sending.

The default value is 1, which limits the adapter to using one persistent connection for the adapter at any one time. This means when ConnectionLifetime is set to Persisted the send adapter will first check to see if an existing connection is present before transmitting data. In the case where a connection exists but another instance of the send port is using the connection the adapter will wait for the connection to become free. A value of 1 effectively serializes all communication for the send port through one persistent connection.

By setting a value greater than 1 a pool of persistent connections can be created. This allows multiple simultaneous persistent connections to be used. When the send adapter is active it will check to see if there are any existing connections. In the case where a connection exists but is being used by another instance of the send port it will attempt to create a new persistent connection. If creating a new persistent connection would exceed the limit specified in this setting the adapter will instead wait for a connection to become free. Setting this to a value greater than 1 allows multiple simultaneous connections to be made while still taking advantage of persistent connections to reduce the overhead of re-connecting.

Note: This only applies to the send adapter.

The default value is 1.

This property can only be configured through the adapter's static handler property page in the BizTalk Server administration console.

This property is not available in the Receiver.

MaxRecordSize Property (OFTP Adapter)

The maximum length of a given record.

Data Type

Integer

Default Value

Remarks

This value determines the maximum length for a record in the outgoing virtual file. When VirtualFileFormat has been set to ffUnstructured or ffText, this value must be zero. When ffFixed or ffVariable, this must be set to a value greater than 0, containing the maximum line length of the outgoing file.

This property is not available in the Receiver.

MaxThreads Property (OFTP Adapter)

The maximum number of threads that the component may consume.

Data Type

Integer

Default Value

Remarks

This property limits the number of concurrent threads that the adapter may consume while completing its work.

This property can only be configured through the adapter's static handler property page in the BizTalk Server administration console.

MaxTransmissionBatchSize Property (OFTP Adapter)

The maximum number of messages that can be sent in a single batch.

Data Type

Integer

Default Value

Remarks

This property controls the maximum size of an outbound message batch.

Note: be careful when modifying this property as it directly effects the efficiency of the transmit adapter. Setting MaxTransmissionBatchSize to a low value in an environment that requires transmission of large quantities of data will result in the adapter accumulating several small batches. If TransmitBatchMode is set to Parallel, this will result in the adapter transmitting many small batches at once and can put a heavy load on the processor.

Conversely, if TransmitBatchMode is set to Serial, setting MaxTransmissionBatchSize to a large value may result in long transmission delays as the adapter will wait on existing work to complete before accepting new messages from the BizTalk Message Engine. This is especially true when the adapter is transmitting large data.

This property can only be configured through the adapter's static handler property page in the BizTalk Server administration console.

This property is not available in the Receiver.

OFTPPort Property (OFTP Adapter)

The port for the OFTP service (default is 3305).

Data Type

Integer

Default Value

3305

Remarks

A valid port number (a value between 1 and 65535) is required for the connection to take place.

This must be set when using ssl, where the default port is 6619.

OFTPServer Property (OFTP Adapter)

The domain name or IP address of the OFTP server.

Data Type

String

Default Value

Remarks

The OFTPServer property specifies the IP address (IP number in dotted internet format) or Domain Name of the OFTP server. It is set before a connection is attempted and cannot be changed once a connection is in progress.

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

Other Property (OFTP Adapter)

Defines a set of configuration settings to be used by the component.

Data Type

String

Default Value

Remarks

The adapter accepts one or more 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 adapter, access to these internal properties is provided through the Other property.

The Other property may be set to one or more configuration settings (name/value pairs). Set one setting per line. For example: configname1=value1 configname2=value2

PollingInterval Property (OFTP Adapter)

The amount of time, in seconds, between download attempts.

Data Type

Integer

Default Value

Remarks

The adapter will wait for the number of seconds indicated before attempting another download.

This property is not available in the Sender.

ReceivedFileDate Property (OFTP Adapter)

The date of the remote file received by the OFTP component.

Data Type

String

Default Value

Remarks

This value contains the date of the remote file being received by the OFTP adapter. It can be read from the context of a message being received by an OFTP adapter receive location.

This property is not available in the Sender.

ReceivedFileName Property (OFTP Adapter)

The name of the remote file received by the OFTP component.

Data Type

String

Default Value

Remarks

This is the filename returned by the server.

This value is also placed in the File.ReceivedFileName and the OFTP.ReceivedFileName context properties. This is to ensure compatibility with other adapters that poll those context properties when filling out macros such as %SourceFileName%.

This property is not available in the Sender.

ReceivedFileSize Property (OFTP Adapter)

The size of the remote file received by the OFTP component.

Data Type

Integer

Default Value

Remarks

This value contains the size of the remote file being received by the OFTP adapter. It can be read from the context of a message being received by an OFTP adapter receive location.

This property is not available in the Sender.

RecipientCert Property (OFTP Adapter)

The recipient certificate of the message.

Data Type

Certificate

Remarks

This property specifies the certificate to use when verifying signed files and receipts as well as encrypting files to be sent. This property must be set when SecureAuthentication has been set to true, sending a file and VirtualFileSecurityLevel has been set to slEncrypted or slEncryptedAndSigned, SignedReceipt has been set to true, or a signed file is being received and the server has not included the certificate in the signature.

This field is used to set a Private Key Certificate.

RequeueEndpoints Property (OFTP Adapter)

Whether to requeue receive endpoints if the polling interval has not been reached.

Data Type

Boolean

Default Value

false

Remarks

This setting controls whether receive endpoints are requeued for later processing if the polling interval has not yet been reached. When this setting is set to No (default) each thread will block until the polling interval for the corresponding receive location is reached. If there exist more active receive locations than MaxThreads it is possible for some threads to block the execution of others since they may be waiting for a polling interval.

When this setting is set to Yes if the polling interval has not been reached the thread will not block until the polling interval is reached, and instead the endpoint will be requeued to be processed later. This lets subsequent endpoints in the queue to be processed.

If MaxThreads is set to a low value and there are a larger number of receive locations setting this to Yes will help assure that polling intervals are respected and receive locations poll in a timely manner.

The default value is No.

This property can only be configured through the adapter's static handler property page in the BizTalk Server administration console.

This property is not available in the Sender.

RuntimeLicense Property (OFTP Adapter)

Specifies the component runtime license key.

Data Type

String

Default Value

Remarks

You can use the RuntimeLicense property to set the runtime key for the adapter license.

This property may be configured on the adapter's static handler property page in the BizTalk Server administration console.

Data Type

Boolean

Default Value

false

Remarks

If true, the adapter will perform secure authentication when connecting to the server. The secure authentication consists of encrypting and decrypting data sent to and from the server, and verifying that this occurred successfully. Secure authentication may be performed in plaintext or ssl mode.

Both Certificate and RecipientCert properties must be populated when this property is set to true.

This is only valid for version 2.0 of the protocol.

ServerPassword Property (OFTP Adapter)

The server's password.

Data Type

Password

Default Value

Remarks

The password assigned to the server in the bilateral agreement. This property must be a string of no more than 8 characters long.

ServerSFIDCode Property (OFTP Adapter)

Server's SFID code.

Data Type

String

Default Value

Remarks

This code is usually the same as the SSID code specified in the ServerSSIDCode property. However, when a company has more than one entity, they may have a different SFID code for each entity in the company.

ServerSSIDCode Property (OFTP Adapter)

The server's SSID code.

Data Type

String

Default Value

Remarks

The identification code of the server. This code may be less than, but no more than 25 characters long. Generally, SSID codes have the following format as specified in rfc 2204 that is based on ISO 6523:


Code Identifier	'O' - Indicates ODETTE assigned the Organization Identifier. Other values can be used for non-ODETTE codes. NOTE: This field is a fixed length of 1 character.
International Code	A code forming part of the Organization Identifier. NOTE: This field may be of variable length up to 4 characters long.
Organization Code	A code forming part of the Organization Identifier. This field may contain the letters A to Z, the digits 0 to 9, and space and hyphen characters. NOTE: This field may be of variable length up to 14 characters long.
Computer Sub-Address	A locally assigned address which uniquely identifies a system within an organization (defined by an Organization Identifier). NOTE: This field may be of variable length up to 6 characters long.

SignedReceipt Property (OFTP Adapter)

Whether or not to require signed receipts.

Data Type

Boolean

Default Value

false

Remarks

When sending a file to a trading partner, set this to true if the file receipt should be signed by the server. When this receipt is received by the adapter, it will be verified during processing.

NOTE: If the server does not attach the public certificate in the signed message, the server's public key must be specified in the RecipientCert property in order for verification to succeed.

This property is not available in the Receiver.

SSLAcceptServerCert Property (OFTP Adapter)

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

Data Type

Certificate

Remarks

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

This property is used to set a Public Key Certificate.

Ordinarily, the system will attempt to locate the public key in trusted certificate stores in the system registry. If a match is found, the certificate is trusted, and the process proceeds without error. If the certificate is not trusted, the adapter will report an error.

You may explicitly set a public key, either to accept a key that is not installed on the system, or to ensure that a specific key is presented. Public key certificates may be loaded from the machine registry or from file. If you click on the ellipses, a certificate selection dialog will open. To select a public key from the system registry, select the System Store tab or the User Store tab, and highlight the appropriate registry store. The list of available certificates will be shown below.

Alternatively, you may specify a public key on file. Select the PEM or Certificate File tabs to load a public key from file. You can use the browse button to examine the file system for the certificate that you wish to use. Public keys typically are stored in .CER, .DER, or .PEM files, but other formats may be used. You can click on the Open button to examine the contents of the certificate. Or, if you have a certificate stored in memory, you can write the contents of the certificate into the text box provided. Note that if you are loading a certificate from memory, the certificate must be Base-64 encoded, or the string representation of the certificate may become corrupted and uninterpretable.

Note: You may also set the Accept Any field to Yes without opening the certificate selection dialog to force the adapter to unilaterally authenticate any server during the security handshake. It is strongly recommended that you use this only for testing purposes. Set the LogMode to Info to cause the adapter to report the server's credentials to Location.

SSLCert Property (OFTP Adapter)

The certificate to use for client authentication during the SSL handshake.

Data Type

Certificate

Remarks

This property is used to assign a specific certificate for SSL client authentication.

This field is used to set a Private Key Certificate.

TempPath Property (OFTP Adapter)

A temporary directory where data can be stored before the component processes it.

Data Type

String

Default Value

Remarks

This property indicates a temporary directory where the adapter can store any data before the adapter processes it. If TempPath is empty, the adapter will receive all data to memory. If set, the adapter will generate and write all inbound data to a temporary file in the specified directory.

Once the file is submitted, the adapter will handle closing the file stream and deleting the temporary file. However, if the adapter is shut down during a transfer some temporary files may be left in the directory. To ensure optimal performance, server administrators should check the directory regularly and remove old or extraneous files.

This property accepts the "%TEMP%" macro, which will be replaced with the default system temporary directory at runtime. Note: by default, this property is empty and the adapter will use memory streams to store all inbound data before submitting it. It is recommended that you use a temporary directory when downloading large batches or batches containing large files to alleviate potential increased memory requirements.

NOTE: When using version 2.0 of the protocol, this property is required.

Timeout Property (OFTP Adapter)

A timeout for the component.

Data Type

Integer

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 adapter will wait for the operation to complete before returning control.

If Timeout expires, and the operation is not yet complete, the adapter fails with an error.

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

Optionally, the behavior of the adapter may be changed to absolute timeouts, i.e. the adapter will wait for a maximum of Timeout seconds since the beginning of the operation, without extending the timeout period during communications.

This behavior is controlled by the AbsoluteTimeout configuration setting.

The default value for the Timeout property is 60 (seconds).

TransmitBatchMode Property (OFTP Adapter)

How the transmitter processes batches.

Data Type

Enumeration

Possible Values

Parallel (0)
Serial (1)

Default Value

Remarks

This property controls how the transmitter processes message batches:


Parallel	The adapter will process however many batches the BizTalk Message Engine sends it. The number of maximum concurrent batches may be controlled by the MaxThreads property.
Serial	The adapter will queue batches from the BizTalk Message Engine and process them one at a time.

This property can only be configured through the adapter's static handler property page in the BizTalk Server administration console.

This property is not available in the Receiver.

TransportLog Property (OFTP Adapter)

Tells the component where and how to report information about its operations.

Data Type

Log

Remarks

This is a Log type property which contains fields describing how and where the adapter will record information about its execution.

This property may be configured on the adapter's static handler property page in the BizTalk Server administration console.

URI Property (OFTP Adapter)

The Uniform Resource Identifier (URI) of the send port or receive location.

Data Type

String

Default Value

Remarks

This property specifies a URI for the send port or receive location. Setting this property is optional.

By default the adapter will automatically generate a URI. You may choose to specify your own value here to be used in place of the generated URI.

If this value is specified it must begin with the correct prefix, as seen in the default value.

UseSSL Property (OFTP Adapter)

Use SSL to access the OFTPServer .

Data Type

Boolean

Default Value

false

Remarks

Use this property to determine whether the adapter uses SSL to connect with the OFTPServer.

This property is only valid when using version 2.0 of the protocol.

Version Property (OFTP Adapter)

Which version of the OFTP protocol the component is using.

Data Type

Enumeration

Possible Values

Ver 12 (0)
Ver 13 (1)
Ver 14 (2)
Ver 20 (3)

Default Value

Remarks

This property is used to specify which version of the oftp protocol the component is using. By default, oftpVer12 (0) is used which is version 1.2 of the protocol. The values oftpVer13(1) and oftpVer14 (2) represent versions 1.3 and 1.4 of the protocol, respectively.

Version 2.0 (oftpVer20) of the protocol must be used when using security functions. UseSSL, SecureAuthentication, VirtualFileSecurityLevel, and Compress all are only valid for version 2.0 of the protocol.

NOTE: TempPath is required when version 2.0 is used.

VirtualFileDate Property (OFTP Adapter)

The date/time stamp for the virtual file.

Data Type

String

Default Value

Remarks

Set this to the date/time stamp for the virtual file before sending. If this is not set when sending a file, the current date/time will be used. This property will accept various date formats.

Supported date formats:

ddd, d MMM yy HH:mm:ss zzz
ddd, d MMM yyyy HH:mm:ss zzz
d MMM yy HH:mm:ss zzz
d MMM yyyy HH:mm:ss zzz
dd-MMM-yyyy HH:mm:ss

VirtualFileFormat Property (OFTP Adapter)

The structure of the outgoing file.

Data Type

Enumeration

Possible Values

Unstructured (0)
Text (1)
Fixed (2)
Variable (3)

Default Value

Remarks

The following values are valid file formats for outgoing virtual files:


Unstructured (0)	The outgoing file is binary and has not structure. There are no records in this type of file.
Text (1)	The outgoing file is a text file that consists of lines containing no more than 2048 characters terminated by CRLF. This type contains no records.
Fixed (2)	The outgoing file is in fixed file format, which means all records are of the same length. For fixed files, the adapter expects the file to be in text format with each line containing the MaxRecordSize characters terminated by a CRLF.
Variable (3)	The outgoing file is a variable file format, meaning all records are of variable length and are no longer than MaxRecordSize. When using this format, the adapter will parse out each record as a line terminated by CRLF. Thus, this type of file must be a text file, and must contain lines with less than MaxRecordSize characters.

Note: When either VirtualFileSecurityLevel has been set to a value other than slNone or Compress has been set to true, all files become ffUnstructured except ffVariable files.

This property is not available in the Receiver.

VirtualFileName Property (OFTP Adapter)

The virtual file name.

Data Type

String

Default Value

"%SourceFilename%"

Remarks

This is the virtual name of the file to be sent to the server. If this property is an empty string, the adapter will create a temporary filename to use as the VirtualFileName.

NOTE: By default, this property is set to "%SourceFilename%", which is a macro that returns the original name of the file as returned.

This property is not available in the Receiver.

VirtualFileSecurityLevel Property (OFTP Adapter)

The level of security for the outgoing file.

Data Type

Enumeration

Possible Values

None (0)
Encrypted (1)
Signed (2)
Encrypted And Signed (3)

Default Value

Remarks

When sending files, set this value to the level of security for the virtual file to send.

When encrypting a file, RecipientCert must be set, and when signing a file, the Certificate property must be set.

The file will be processed to a temporary file before being sent, and thus the TempPath property is required with encrypting or signing a file.

This is only valid for version 2.0 of the protocol.

This property is not available in the Receiver.

Certificate Type

The digital certificate being used.

Remarks

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

Fields

Store
String
Default Value: "MY"

The name of the certificate store for the client certificate.

The StoreType field specifies the type of the certificate store specified by Store. If the store is password protected, specify the password in StorePassword.

Store is used in conjunction with the Subject field in order to specify client certificates. If Store has a value, and Subject is set, a search for a certificate is initiated. Please refer to the Subject field for details.

Designations of certificate stores are platform-dependent.

The following are designations of the most common User and Machine certificate stores in Windows:


MY	A certificate store holding personal certificates with their associated private keys.
CA	Certifying authority certificates.
ROOT	Root certificates.
SPC	Software publisher certificates.

In Java, the certificate store normally is a file containing certificates and optional private keys.

When the certificate store type is PFXFile, this property must be set to the name of the file. When the type is PFXBlob, the property must be set to the binary contents of a PFX file (i.e. PKCS12 certificate store).

If the provider is OpenSSL, the certificate store is a file containing a certificate and a private key. This property must be set to the name of the file.

StorePassword
String
Default Value: ""

If the certificate store is of a type that requires a password, this property is used to specify that password in order to open the certificate store.

StoreType
CertStoreTypes
Default Value: 0

The type of certificate store for this certificate.

The adapter supports both public and private keys in a variety of formats. When the cstAuto value is used, the adapter will automatically determine the type. This field can take one of the following values:


0 (cstUser - default)	For Windows, this specifies that the certificate store is a certificate store owned by the current user. Note: This store type is not available in Java.
1 (cstMachine)	For Windows, this specifies that the certificate store is a machine store. Note: This store type is not available in Java.
2 (cstPFXFile)	The certificate store is the name of a PFX (PKCS#12) file containing certificates.
3 (cstPFXBlob)	The certificate store is a string (binary or Base64-encoded) representing a certificate store in PFX (PKCS#12) format.
4 (cstJKSFile)	The certificate store is the name of a Java Key Store (JKS) file containing certificates. Note: This store type is only available in Java.
5 (cstJKSBlob)	The certificate store is a string (binary or Base64-encoded) representing a certificate store in Java Key Store (JKS) format. Note: This store type is only available in Java.
6 (cstPEMKeyFile)	The certificate store is the name of a PEM-encoded file that contains a private key and an optional certificate.
7 (cstPEMKeyBlob)	The certificate store is a string (binary or Base64-encoded) that contains a private key and an optional certificate.
8 (cstPublicKeyFile)	The certificate store is the name of a file that contains a PEM- or DER-encoded public key certificate.
9 (cstPublicKeyBlob)	The certificate store is a string (binary or Base64-encoded) that contains a PEM- or DER-encoded public key certificate.
10 (cstSSHPublicKeyBlob)	The certificate store is a string (binary or Base64-encoded) that contains an SSH-style public key.

22 (cstBCFKSBlob)	The certificate store is a string (binary or Base64-encoded) representing a certificate store in BCFKS (Bouncy Castle FIPS Key Store) format. Note: This store type is only available in Java and .NET.
23 (cstPKCS11)	The certificate is present on a physical security key accessible via a PKCS#11 interface. To use a security key, the necessary data must first be collected using the CERTMGR adapter. The ListStoreCertificates method may be called after setting CertStoreType to `cstPKCS11`, CertStorePassword to the PIN, and CertStore to the full path of the PKCS#11 DLL. The certificate information returned in the CertList event's `CertEncoded` parameter may be saved for later use. When using a certificate, pass the previously saved security key information as the Store and set StorePassword to the PIN. Code Example. SSH Authentication with Security Key: `certmgr.CertStoreType = CertStoreTypes.cstPKCS11; certmgr.OnCertList += (s, e) => { secKeyBlob = e.CertEncoded; }; certmgr.CertStore = @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll"; certmgr.CertStorePassword = "123456"; //PIN certmgr.ListStoreCertificates(); sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11, secKeyBlob, "123456", "*"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22);`
99 (cstAuto)	The store type is automatically detected from the input data. This setting may be used with both public and private keys and can detect any of the supported formats automatically.

Subject
String
Default Value: ""

The subject of the certificate used for client authentication.

When this property is set, a search is performed in the current certificate store certificate with matching subject.

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

When setting the property to a partial subject, CN= should be omitted. For example, the following code would find the certificate with subject CN=Test Certificate, OU=People, C=US

Example (Searching with partial subject)

Control.CertSubject = "Test"

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

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

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

Thumbprint
String (read-only)
Default Value: ""

The thumbprint of the certificate.

This field is used to specify the thumbprint of the certificate. When there are multiple certificates in the store that have the same subject, the thumbprint will be used to distinguish between them.

Constructors

Constructors are only relevant when configuring adapters in orchestrations.

public Certificate();

Creates a instance whose properties can be set.

public Certificate(string certificateFile);

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

public Certificate(byte[] certificateData);

Parses CertificateData as an X509 public key.

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

CertStoreType identifies the type of certificate store to use. See for descriptions of the different certificate stores. Store is a file containing the certificate store. StorePassword is the password used to protect the store.

After the store has been successfully opened, the constructor will attempt to find the certificate identified by Subject . This can be either a complete or a substring match of the X509 certificate's subject Distinguished Name (DN).

public Certificate(CertStoreTypes certStoreType, string store, string storePassword, byte[] encoded);

After the store has been successfully opened, the constructor will load Encoded as an X509 certificate and search the opened store for a corresponding private key.

public Certificate(CertStoreTypes certStoreType, byte[] storeBlob, string storePassword, string subject);

CertStoreType identifies the type of certificate store to use. See for descriptions of the different certificate stores. Store is a string (binary- or base64-encoded) containing the certificate store. StorePassword is the password used to protect the store.

public Certificate(CertStoreTypes certStoreType, byte[] storeBlob, string storePassword, byte[] encoded);

After the store has been successfully opened, the constructor will load Encoded as an X509 certificate and search the opened store for a corresponding private key.

Firewall Type

The firewall the component will connect through.

Remarks

When connecting through a firewall, this type is used to specify different properties of the firewall such as the firewall Host and the FirewallType.

Fields

Default Value: ""

Name or IP address of firewall (optional). If a Host is given, requested connections will be authenticated through the specified firewall when connecting.

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

Password
String
Default Value: ""

A password if authentication is to be used when connecting through the firewall. If Host is specified, the User and Password fields are used to connect and authenticate to the given firewall. If the authentication fails, a trappable error is fired.

Port
Integer
Default Value: 0

The TCP port for the firewall Host. See the description of the Host field for details.

Note that the Port is set automatically when FirewallType is set to a valid value. See the description of the FirewallType field for details.

User
String
Default Value: ""

A user name if authentication is to be used connecting through a firewall. If the Host is specified, the User and Password fields are used to connect and authenticate to the given Firewall. If the authentication fails, a trappable error is fired.

Constructors

Remarks

This describes how and where the adapter will record information describing its execution.

Fields

Location
String
Default Value: "Application"

This field describes the location where the logging information is to be written.

If the EventLog LogType has been chosen, this field must contain the name of the Event Log to which the information should be written. The default value for this field is "Application". If a value other than "Application" is set the computer must be restarted for the change to take effect. Note that the same event log must be used for all send ports and receive locations that use the same adapter.

If the File LogType has been chosen, this field must contain the location of the file to write logging information to on the file system.

The adapter also supports logging to files based on the current date and time. This allows for log files to be organized by days, months, or other intervals as specified. When specifying a log filename include a valid .NET date and time format string within the < and > characters. For instance C:\logs\sftp_<yyyyMMdd>.log or C:\logs\as2_<yyyyMMdd>T<hhmm>.log.

LogMode

Constructors

Constructors are only relevant when configuring adapters in orchestrations.

public Log();

public Log(LogTypes logType, string location, LogModes logMode);

Config Settings (OFTP Adapter)

The adapter 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 adapter, access to these internal properties is provided through the Other property.

OFTP Config Settings

OverwriteTempFiles: Whether to overwrite files in the directory specified by TempPath.

If this is set to True, files present in the directory specified by TempPath may be overwritten. The default value is False.

ReceivedFileNameFormat: The name format of received files.

This setting specifies the format used when determining the local filename of a received file. The use of macros is supported to provide flexibility. This setting may include one or more of the following values:

%VirtualFileName%
%VirtualFileDate%
%Originator%
%Destination%
%UserData%
%CurrentTime%
%GUID%

An example value is "%VirtualFileName%_%VirtualFileDate%_%Destination%". The default value is "%VirtualFileName%".

The '%VirtualFileDate%' macro also supports date formatting through the use of an optional DateTime format string. The format of the macro with the date format string included is:

%VirtualFileDate:CustomFormat%

For example: "%VirtualFileDate:yyyyMMddHHmmssffff%"

SSL Config Settings

ReuseSSLSession: Determines if the SSL session is reused.

If set to true, the adapter 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 adapter is the same.

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.

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

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 adapter 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 UseInternalSecurityAPI is False (default): // The "Other" property could contain ONE of the following lines: SSLEnabledCipherSuites=* SSLEnabledCipherSuites=CALG_AES_256 SSLEnabledCipherSuites=CALG_AES_256;CALG_3DES Possible values when UseInternalSecurityAPI is False (default) include:

If SSLEnabledProtocols is configured to use TLS 1.3 the following values are supported:

TLS_AES_128_GCM_SHA256
TLS_AES_256_GCM_SHA384

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) (Experimental)
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)

Note: TLS 1.1 and TLS1.2 support are only available starting with Windows 7.

Note: Enabling TLS 1.3 will automatically set UseInternalSecurityAPI to True.

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

This setting specifies whether the transport log contains the full certificate chain. By default this value is False and only the leaf certificate will be present.

If set to True all certificates returned by the server will be present in the transport log. This includes the leaf certificate, any intermediate certificate, and the root certificate.

Note: When UseInternalSecurityAPI is set to True this value is automatically set to True. This is needed for proper validation when using the internal provider.

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).

TLS12SignatureAlgorithms: Defines the allowed TLS 1.2 signature algorithms when UseInternalSecurityAPI is True.

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

When specified the adapter 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 adapter will fail with an error.

The format of this value is a comma separated list of hash-signature combinations. For instance: // The "Other" could contain ALL of these lines: UseInternalSecurityAPI=true SSLEnabledProtocols=3072 TLS12SignatureAlgorithms=sha1-rsa,sha1-dsa,sha256-rsa,sha256-dsa The default value for this setting is "sha1-rsa,sha1-dsa,sha224-rsa,sha224-dsa,sha256-rsa,sha256-dsa,sha384-rsa,sha384-dsa,sha512-rsa,sha512-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 UseInternalSecurityAPI is set to True, 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:

"rsa_pkcs1_sha256" (default)
"rsa_pkcs1_sha384" (default)
"rsa_pkcs1_sha512" (default)

The default value is rsa_pkcs1_sha256,rsa_pkcs1_sha384,rsa_pkcs1_sha512. 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)

General 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.

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

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

In multihomed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the adapter initiate connections (or accept in the case of server adapters) only through that interface.

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

TcpNoDelay: Whether or not to delay when sending packets.

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

By default, this configuration setting is set to False.

UseInternalSecurityAPI: Whether or not to use the system security libraries or an internal implementation.

When set to False, the adapter will use the system security libraries by default to perform cryptographic functions where applicable. In this case, calls to unmanaged code will be made. In certain environments, this is not desirable. To use a completely managed security implementation, set this setting to True.

Setting this configuration setting to True tells the adapter to use the internal implementation instead of using the system security libraries.

On Windows, this setting is set to False by default. On Linux/macOS, this setting is set to True by default.

If using the .NET Standard Library, this setting will be True on all platforms. The .NET Standard library does not support using the system security libraries.

Note: This setting is static. The value set is applicable to all adapters used in the application.

When this value is set, the product's system dynamic link library (DLL) is no longer required as a reference, as all unmanaged code is stored in that file.

Supported Macros

The adapter also supports the following Macros. These values are not case sensitive and would be supplied to a property in the form %MacroName%.

TempThis is resolved to the full path to the system's temporary directory. MessageIDGlobally unique identifier (GUID) of the message in BizTalk Server. SourceFileNameThe original file name. This includes the extension and excludes the file path, for example, Sample.xml SourceFileNameNoExtThe original file name without the extension or file path, for example, Sample RemoteFileNameThe name of the file as it was uploaded to the remote server. This includes the extension and excludes the file path, for example, Sample.xml. Valid only for AS3, FTP, and SFTP Send Adapters. DestinationPartyName of the destination party. DestinationPartyQualifierQualifier of the destination party. SourcePartyName of the source party. SourcePartyQualifierQualifier of the source party.
