# OFTPClient Component

The OFTPClient component implements the Odette File Transfer Protocol.

## Syntax

```text
TibeOFTPClient
```

## Remarks

The OFTPClient component may be used to send and receive OFTP files to and from an OFTP server.

**Receiving Files**

 The OFTPClient [ReceiveFiles](#receivefiles-method-oftpclient-component) function requires certain server properties be set. You must set the [RemoteHost](#remotehost-property-oftpclient-component) property to the remote location of the desired OFTP server. You may also set a [RemotePort](#remoteport-property-oftpclient-component) if the server is not set to the default protocol port. For client authorization, you must set the [ClientSSIDCode](#clientssidcode-property-oftpclient-component), [ClientSFIDCode](#clientsfidcode-property-oftpclient-component), and [ClientPassword](#clientpassword-property-oftpclient-component) properties. And, for server authentication, you must set the [ServerSSIDCode](#serverssidcode-property-oftpclient-component), [ServerSFIDCode](#serversfidcode-property-oftpclient-component), and [ServerPassword](#serverpassword-property-oftpclient-component) properties.

The component will connect to the OFTP server and download all files in the server's outgoing queue, and write these files to the directory specified by [DownloadDirectory](#downloaddirectory-property-oftpclient-component). The component creates a default location on the local machine based on the values of the [DownloadDirectory](#downloaddirectory-property-oftpclient-component) and the Virtual Filename as received from the server. If a different location is preferred, you may set the **LocalFile** parameter of the [StartTransfer](#starttransfer-event-oftpclient-component) event.

**Sending Files**

 The OFTPClient [SendFile](#sendfile-method-oftpclient-component) function requires the same server and authentication properties to be set as the [ReceiveFiles](#receivefiles-method-oftpclient-component) function.

The component will connect to the OFTP server and upload the file contained by the **LocalFile** parameter. It uses the name specified by **VirtualFileName** when sending to the server. If this is not specified, the filename of the local file is parsed and used as the virtual filename.

# Certificate Property ([OFTPClient](#oftpclient-component) Component)

The current selected certificate.

## Syntax

*Delphi Syntax*

```text
property Certificate: TibeCertificate read get_Certificate write set_Certificate;
```

## Remarks

This property is populated when a specified certificate is found or loaded by the component. Certificate is used for specifying private keys. Set this property to a valid [Certificate](#certificate-type) object to perform different operations such as session authentication, signing a file or receipt, or decryption. To set a certificate, you may set the [Encoded](#Certificate_f_Encoded) field to the encoded certificate. To select a certificate, use the [Store](#Certificate_f_Store) and [Subject](#Certificate_f_Subject) fields.

 Please refer to the [Certificate](#certificate-type) type for a complete list of fields.

# ClientPassword Property ([OFTPClient](#oftpclient-component) Component)

The client's password.

## Syntax

*Delphi Syntax*

```text
property ClientPassword: String read get_ClientPassword write set_ClientPassword;
```

## 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 ([OFTPClient](#oftpclient-component) Component)

Client's SFID code.

## Syntax

*Delphi Syntax*

```text
property ClientSFIDCode: String read get_ClientSFIDCode write set_ClientSFIDCode;
```

## Default Value

''

## Remarks

The SFID code identifies the origin or destination party that is sending or receiving a file, while the SSID code identifies the party that a session is established with. If the SFID and SSID codes do not match, then the party the session is established with is acting as an intermediary, and the party identified by the SFID code is either the origin or final destination.

When acting as an intermediary the component will not perform any security services (i.e. sign, verify, encrypt, decrypt). Security services are to be performed by the origin or destination only. Data should simply be passed along by an intermediary.

# ClientSSIDCode Property ([OFTPClient](#oftpclient-component) Component)

The client's SSID code.

## Syntax

*Delphi Syntax*

```text
property ClientSSIDCode: String read get_ClientSSIDCode write set_ClientSSIDCode;
```

## 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 ([OFTPClient](#oftpclient-component) Component)

Whether or not to compress the outgoing file.

## Syntax

*Delphi Syntax*

```text
property Compress: Boolean read get_Compress write set_Compress;
```

## Default Value

false

## Remarks

When sending a file to the trading partner, set this to true for the component to compress the file before sending. The file will first be compressed to a temporary file before being sent.

Note that this is only applicable when Version 2.0 of the protocol is used as indicated by [Version](#version-property-oftpclient-component).

This property is not available at design time.

# Connected Property ([OFTPClient](#oftpclient-component) Component)

Shows whether the component is connected.

## Syntax

*Delphi Syntax*

```text
property Connected: Boolean read get_Connected;
```

## Default Value

false

## Remarks

Use this property to determine whether the component is connected to the remote host or not.

Use the [Connect](#connect-method-oftpclient-component) and [Disconnect](#disconnect-method-oftpclient-component) methods to manage the connection.

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

# DownloadDirectory Property ([OFTPClient](#oftpclient-component) Component)

## Syntax

*Delphi Syntax*

```text
property DownloadDirectory: String read get_DownloadDirectory write set_DownloadDirectory;
```

## Default Value

'./'

## Remarks

This property contains the location on disk of the folder the component will write received files to. The default for this property is "./", which is the current working directory.

Note: If this property is set to empty string data will not be written to disk and instead will be available through the [Transfer](#transfer-event-oftpclient-component) event.

# EncryptionAlgorithm Property ([OFTPClient](#oftpclient-component) Component)

The encryption algorithm.

## Syntax

*Delphi Syntax*

```text
property EncryptionAlgorithm: TibeOftpclientEncryptionAlgorithms read get_EncryptionAlgorithm write set_EncryptionAlgorithm;
TibeOftpclientEncryptionAlgorithms = (
  encra3DES,
  encraAES
);
```

## Default Value

encra3DES

## Remarks

In order to use encryption, you must set the [VirtualFileSecurityLevel](#virtualfilesecuritylevel-property-oftpclient-component) property. The supported algorithms for encryption are:

|  |  |
| --- | --- |
| 3DES (0) | Triple Data Encryption Standard. |
| AES (1) | Advanced Encryption Standard CBC mode with a 256-bit key. |

This property is not available at design time.

# Firewall Property ([OFTPClient](#oftpclient-component) Component)

A set of properties related to firewall access.

## Syntax

*Delphi Syntax*

```text
property Firewall: TibeFirewall read get_Firewall write set_Firewall;
```

## Remarks

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

 Please refer to the [Firewall](#firewall-type) type for a complete list of fields.

# LocalHost Property ([OFTPClient](#oftpclient-component) Component)

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

## Syntax

*Delphi Syntax*

```text
property LocalHost: String read get_LocalHost write set_LocalHost;
```

## Default Value

''

## Remarks

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

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

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

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

# MaxRecordSize Property ([OFTPClient](#oftpclient-component) Component)

The maximum length of a given record.

## Syntax

*Delphi Syntax*

```text
property MaxRecordSize: Integer read get_MaxRecordSize write set_MaxRecordSize;
```

## Default Value

0

## Remarks

This value determines the maximum length for a record in the outgoing virtual file. When [VirtualFileFormat](#virtualfileformat-property-oftpclient-component) 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.

# Overwrite Property ([OFTPClient](#oftpclient-component) Component)

Whether or not the component should overwrite files during transfer.

## Syntax

*Delphi Syntax*

```text
property Overwrite: Boolean read get_Overwrite write set_Overwrite;
```

## Default Value

false

## Remarks

This property is a value indicating whether or not the component should overwrite downloaded files. If Overwrite is false, an error will be thrown whenever the local file exists before a receive operation.

# RecipientCert Property ([OFTPClient](#oftpclient-component) Component)

The recipient certificate of the message.

## Syntax

*Delphi Syntax*

```text
property RecipientCert: TibeCertificate read get_RecipientCert write set_RecipientCert;
```

## 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](#secureauthentication-property-oftpclient-component) has been set to true, sending a file and [VirtualFileSecurityLevel](#virtualfilesecuritylevel-property-oftpclient-component) has been set to *slEncrypted* or *slEncryptedAndSigned*, [SignedReceipt](#signedreceipt-property-oftpclient-component) has been set to true, or a signed file is being received and the server has not included the certificate in the signature.

The RecipientCert property must be filled out with a valid public key [Certificate](#certificate-type) type object. To set a certificate, you may set the [Encoded](#Certificate_f_Encoded) field to the encoded certificate. To select a certificate, use the [Store](#Certificate_f_Store) and [Subject](#Certificate_f_Subject) fields.

This property is not available at design time.

 Please refer to the [Certificate](#certificate-type) type for a complete list of fields.

# RemoteHost Property ([OFTPClient](#oftpclient-component) Component)

The domain name or IP address of the OFTP server.

## Syntax

*Delphi Syntax*

```text
property RemoteHost: String read get_RemoteHost write set_RemoteHost;
```

## Default Value

''

## Remarks

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

If the component 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.

# RemotePort Property ([OFTPClient](#oftpclient-component) Component)

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

## Syntax

*Delphi Syntax*

```text
property RemotePort: Integer read get_RemotePort write set_RemotePort;
```

## Default Value

3305

## Remarks

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.

When [UseSSL](#usessl-property-oftpclient-component) is set to True this property will be set to 6619.

This property is not available at design time.

# SecureAuthentication Property ([OFTPClient](#oftpclient-component) Component)

Whether or not the component should perform secure Odette authentication.

## Syntax

*Delphi Syntax*

```text
property SecureAuthentication: Boolean read get_SecureAuthentication write set_SecureAuthentication;
```

## Default Value

false

## Remarks

If true, the component 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](#certificate-property-oftpclient-component) and [RecipientCert](#recipientcert-property-oftpclient-component) properties must be populated when this property is set to true.

This is only valid for version 2.0 of the protocol.

This property is not available at design time.

# ServerPassword Property ([OFTPClient](#oftpclient-component) Component)

The server's password.

## Syntax

*Delphi Syntax*

```text
property ServerPassword: String read get_ServerPassword write set_ServerPassword;
```

## 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 ([OFTPClient](#oftpclient-component) Component)

Server's SFID code.

## Syntax

*Delphi Syntax*

```text
property ServerSFIDCode: String read get_ServerSFIDCode write set_ServerSFIDCode;
```

## Default Value

''

## Remarks

The SFID code identifies the origin or destination party that is sending or receiving a file, while the SSID code identifies the party that a session is established with. If the SFID and SSID codes do not match, then the party the session is established with is acting as an intermediary, and the party identified by the SFID code is either the origin or final destination.

When acting as an intermediary the component will not perform any security services (i.e. sign, verify, encrypt, decrypt). Security services are to be performed by the origin or destination only. Data should simply be passed along by an intermediary.

# ServerSSIDCode Property ([OFTPClient](#oftpclient-component) Component)

The server's SSID code.

## Syntax

*Delphi Syntax*

```text
property ServerSSIDCode: String read get_ServerSSIDCode write set_ServerSSIDCode;
```

## 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 ([OFTPClient](#oftpclient-component) Component)

Whether or not to require signed receipts.

## Syntax

*Delphi Syntax*

```text
property SignedReceipt: Boolean read get_SignedReceipt write set_SignedReceipt;
```

## 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 component, 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](#recipientcert-property-oftpclient-component) property in order for verification to succeed.

This property is not available at design time.

# SSLAcceptServerCert Property ([OFTPClient](#oftpclient-component) Component)

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

## Syntax

*Delphi Syntax*

```text
property SSLAcceptServerCert: TibeCertificate read get_SSLAcceptServerCert write set_SSLAcceptServerCert;
```

## Remarks

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

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

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

 Please refer to the [Certificate](#certificate-type) type for a complete list of fields.

# SSLCert Property ([OFTPClient](#oftpclient-component) Component)

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

## Syntax

*Delphi Syntax*

```text
property SSLCert: TibeCertificate read get_SSLCert write set_SSLCert;
```

## Remarks

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

 Please refer to the [Certificate](#certificate-type) type for a complete list of fields.

# Timeout Property ([OFTPClient](#oftpclient-component) Component)

This property includes the timeout for the component.

## Syntax

*Delphi Syntax*

```text
property Timeout: Integer read get_Timeout write set_Timeout;
```

## Default Value

60

## Remarks

If the Timeout property is set to 0, all operations return immediately, potentially failing with a *WOULDBLOCK* error if data cannot be sent immediately.

If Timeout is set to a positive value, data is sent in a blocking manner and the component will wait for the operation to complete before returning control. The component will handle any potential *WOULDBLOCK* errors internally and automatically retry the operation for a maximum of Timeout seconds.

The component will use [DoEvents](#doevents-method-oftpclient-component) to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not freeze and remains responsive.

If Timeout expires, and the operation is not yet complete, the component raises an exception.

NOTE: By default, all timeouts are *inactivity timeouts*, that is, 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.

# TrustedCerts Property ([OFTPClient](#oftpclient-component) Component)

A collection of trusted CA certificates.

## Syntax

*Delphi Syntax*

```text
property TrustedCerts: TibeCertificateList read get_TrustedCerts write set_TrustedCerts;
```

## Remarks

If this collection is populated the component will validate any certificates that are loaded against the CA certificates specified here.

If this collection is not populated no validation will occur. Certificates are imported into this collection by calling the [ImportTrustedCerts](#importtrustedcerts-method-oftpclient-component) method.

# UseSSL Property ([OFTPClient](#oftpclient-component) Component)

Use SSL to access the RemoteHost .

## Syntax

*Delphi Syntax*

```text
property UseSSL: Boolean read get_UseSSL write set_UseSSL;
```

## Default Value

false

## Remarks

Use this property to determine whether the component uses SSL to connect with the [RemoteHost](#remotehost-property-oftpclient-component).

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

Note: Setting this property to True will set [RemotePort](#remoteport-property-oftpclient-component) to 6619.

This property is not available at design time.

# Version Property ([OFTPClient](#oftpclient-component) Component)

Which version of the OFTP protocol the component is using.

## Syntax

*Delphi Syntax*

```text
property Version: TibeTOFTPVersions read get_Version write set_Version;
TibeTOFTPVersions = (
  oftpVer12,
  oftpVer13,
  oftpVer14,
  oftpVer20
);
```

## Default Value

oftpVer20

## Remarks

This property specifies which version of the OFTP protocol to use. Possible values are:

|  |  |
| --- | --- |
| 0 (oftpVer12) | 1.2 |
| 1 (oftpVer13) | 1.3 |
| 2 (oftpVer14) | 1.4 |
| 3 (oftpVer20 - default) | 2.0 |

 The default value is oftpVer20 (Version 2.0).

Note: Version 2.0 (oftpVer20) of the protocol must be used when using security functions. The following properties are only applicable when using Version 2.0:

- [UseSSL](#usessl-property-oftpclient-component)
- [SecureAuthentication](#secureauthentication-property-oftpclient-component)
- [VirtualFileSecurityLevel](#virtualfilesecuritylevel-property-oftpclient-component)
- [Compress](#compress-property-oftpclient-component)

# VirtualFileDate Property ([OFTPClient](#oftpclient-component) Component)

The date/time stamp for the virtual file.

## Syntax

*Delphi Syntax*

```text
property VirtualFileDate: String read get_VirtualFileDate write set_VirtualFileDate;
```

## 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, but will return the following format only: "MM/dd/yyyy HH:mm:ss".

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

- yyyyMMddHHmmssZ
- yyMMddHHmmsszzzz
- yyyyMMddHHmmsszzzz
- yyyyMMddHHmmssffff
- MM/dd/yyyy HH:mm:ss

# VirtualFileFormat Property ([OFTPClient](#oftpclient-component) Component)

The structure of the outgoing file.

## Syntax

*Delphi Syntax*

```text
property VirtualFileFormat: TibeVirtualFileFormats read get_VirtualFileFormat write set_VirtualFileFormat;
TibeVirtualFileFormats = (
  ffUnstructured,
  ffText,
  ffFixed,
  ffVariable
);
```

## Default Value

ffUnstructured

## Remarks

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

|  |  |
| --- | --- |
| 0 (Unstructured - default) | The outgoing file is binary and has not structure. There are no records in this type of file. |
| 1 (Text) | 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. |
| 2 (Fixed) | The outgoing file is in fixed file format, which means all records are of the same length. For fixed files, the component expects the file to be in text format with each line containing the [MaxRecordSize](#maxrecordsize-property-oftpclient-component) characters terminated by a CRLF. |
| 3 (Variable) | The outgoing file is a variable file format, meaning all records are of variable length and are no longer than [MaxRecordSize](#maxrecordsize-property-oftpclient-component). When using this format, the component 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](#maxrecordsize-property-oftpclient-component) characters. |

Note: When either [VirtualFileSecurityLevel](#virtualfilesecuritylevel-property-oftpclient-component) has been set to a value other than *slNone* or [Compress](#compress-property-oftpclient-component) has been set to true, all files become *ffUnstructured* except *ffVariable* files.

This property is not available at design time.

# VirtualFileSecurityLevel Property ([OFTPClient](#oftpclient-component) Component)

The level of security for the file.

## Syntax

*Delphi Syntax*

```text
property VirtualFileSecurityLevel: TibeVirtualFileSecurityLevels read get_VirtualFileSecurityLevel write set_VirtualFileSecurityLevel;
TibeVirtualFileSecurityLevels = (
  slNone,
  slEncrypted,
  slSigned,
  slEncryptedAndSigned
);
```

## Default Value

slNone

## Remarks

When sending files, set this value to the level of security for the next virtual file to send. After receiving a file, this will be set to the level of security of the last file received.

When encrypting a file, [RecipientCert](#recipientcert-property-oftpclient-component) must be set, and when signing a file, the [Certificate](#certificate-property-oftpclient-component) must be set.

The file will be processed to a temporary file before being sent.

This is only valid for version 2.0 of the protocol.

This property is not available at design time.

# ChangeDirection Method ([OFTPClient](#oftpclient-component) Component)

Sends a Change Direction (CD) command.

## Syntax

*Delphi Syntax*

```text
procedure ChangeDirection();
```

## Remarks

This method sends a Change Direction (CD) command to the remote host when called. In normal operation this should not be used. This should only be used if a condition arises where you must manually change the speaker when communicating with the remote host.

# Config Method ([OFTPClient](#oftpclient-component) Component)

Sets or retrieves a configuration setting.

## Syntax

*Delphi Syntax*

```text
function Config(ConfigurationString: String): String;
```

## Remarks

Config is a generic method available in every component. It is used to set and retrieve [configuration settings](#config-settings-oftpclient-component) for the component.

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

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

To read (query) the value of a [configuration setting](#config-settings-oftpclient-component), you must call *Config("PROPERTY")*. The value will be returned as a string.

# Connect Method ([OFTPClient](#oftpclient-component) Component)

This method connects to the FTP server without logging in.

## Syntax

*Delphi Syntax*

```text
procedure Connect();
```

## Remarks

This method establishes a connection with the [RemoteHost](#remotehost-property-oftpclient-component) but does not log in. In most cases, it is recommended to use the [Logon](#logon-method-oftpclient-component) method, which will both establish a connection and log in to the server.

This method may be useful in cases in which it is desirable to separate the connection and logon operations, for instance, confirming that a host is available by first creating the connection.

# Disconnect Method ([OFTPClient](#oftpclient-component) Component)

This method disconnects from the server without first logging off.

## Syntax

*Delphi Syntax*

```text
procedure Disconnect();
```

## Remarks

This method immediately disconnects from the server without first logging off.

In most cases, the [Logoff](#logoff-method-oftpclient-component) method should be used to log off and disconnect from the server. Call the Disconnect method in cases in which it is desirable to immediately disconnect without first logging off.

# DoEvents Method ([OFTPClient](#oftpclient-component) Component)

This method processes events from the internal message queue.

## Syntax

*Delphi Syntax*

```text
procedure DoEvents();
```

## Remarks

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

# ExchangeCertificate Method ([OFTPClient](#oftpclient-component) Component)

Exchange a certificate with the remote host.

## Syntax

*Delphi Syntax*

```text
procedure ExchangeCertificate(CertificateStore: String; CertificateExchangeType: Integer);
```

## Remarks

If the remote host supports the certificate exchange feature of OFTP 2.0 this method may be used to send and/or request certificates.

The *CertificateStore* parameter specifies the location of the certificate to be exchanged. In most cases this will be the path to a .cer file on disk. If the certificate is in another format or is installed to the Windows certificate store please see [ExchangeCertStoreType](#ExchangeCertStoreType) and [ExchangeCertSubject](#ExchangeCertSubject) for more information.

The *CertificateExchangeType* parameter determines the type of request. Possible values are:

|  |  |
| --- | --- |
| 0 | Request: The component will send the certificate file specified. The remote host will respond with a certificate of it's own. The response may be in a separate session. |
| 1 | Replace: The component will send the certificate file specified. No certificate is expected in response. The certificate sent here invalidates any previous certificates the remote host has stored. |
| 2 | Deliver: The component will send the certificate file specified. This is used to respond to a certificate request. It may also be used to send new additional certificates to the remote host. This will not invalidate previous certificates the remote host has stored. |

 When the remote host sends a certificate to the component the received certificate will be provided through the [CertificateReceived](#certificatereceived-event-oftpclient-component) event.

# ImportTrustedCerts Method ([OFTPClient](#oftpclient-component) Component)

Imports a list of trusted CA certificates.

## Syntax

*Delphi Syntax*

```text
procedure ImportTrustedCerts();
```

## Remarks

When ImportTrustedCerts is called the component will import the CA certificates from the source specified by [TrustedCertsData](#TrustedCertsData) into the [TrustedCerts](#trustedcerts-property-oftpclient-component) collection.

The component will then validate the trust of certificates when they are loaded.

If trusted CA certificates are not imported no validation will occur (default).

See also [FailOnUntrustedCert](#FailOnUntrustedCert).

# Interrupt Method ([OFTPClient](#oftpclient-component) Component)

This method interrupts the current action.

## Syntax

*Delphi Syntax*

```text
procedure Interrupt();
```

## Remarks

This method interrupts the current action. If you use [SendFile](#sendfile-method-oftpclient-component) to upload a file, the component will run synchronously until the upload is completed. This method will allow you to stop the file from uploading without disconnecting from the host.

# Logoff Method ([OFTPClient](#oftpclient-component) Component)

Logoff from the OFTP server.

## Syntax

*Delphi Syntax*

```text
procedure Logoff();
```

## Remarks

Logoff from the OFTP server. If that fails, the connection is terminated by the local host.

# Logon Method ([OFTPClient](#oftpclient-component) Component)

Logon to the OFTP RemoteHost using the current client credentials.

## Syntax

*Delphi Syntax*

```text
procedure Logon();
```

## Remarks

Logon to the OFTP server using the current [ClientSSIDCode](#clientssidcode-property-oftpclient-component), [ClientSFIDCode](#clientsfidcode-property-oftpclient-component), and [ClientPassword](#clientpassword-property-oftpclient-component). The component will also check the corresponding server credentials, [ServerSSIDCode](#serverssidcode-property-oftpclient-component), [ServerSFIDCode](#serversfidcode-property-oftpclient-component), and [ServerPassword](#serverpassword-property-oftpclient-component).

# ReceiveFiles Method ([OFTPClient](#oftpclient-component) Component)

Receive any files queued to be sent from the server.

## Syntax

*Delphi Syntax*

```text
procedure ReceiveFiles();
```

## Remarks

This method connects to the server, and receives any files the server has in its outgoing queue to this particular partner. The files are downloaded to the directory specified by the [DownloadDirectory](#downloaddirectory-property-oftpclient-component) property.

# Reset Method ([OFTPClient](#oftpclient-component) Component)

Resets the state of the control.

## Syntax

*Delphi Syntax*

```text
procedure Reset();
```

## Remarks

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

# SendEndResponse Method ([OFTPClient](#oftpclient-component) Component)

Sends an EERP/NERP asynchronously.

## Syntax

*Delphi Syntax*

```text
procedure SendEndResponse(VirtualFileName: String; VirtualFileDate: String; Destination: String; Originator: String; Creator: String; ReasonCode: Integer; ReasonText: String; FileHash: String; Signature: String);
```

## Remarks

This method sends an EERP/NERP. By default the component will automatically respond with an EERP/NERP when receiving a file. To respond asynchronously instead this method may be used.

To respond asynchronously first set the *SendEndResponse* parameter of the [EndTransfer](#endtransfer-event-oftpclient-component) event to False. This instructs the component to not send a response automatically. Within the [EndTransfer](#endtransfer-event-oftpclient-component) event you must also save the values that are required parameters for this method. This includes *FileHash*, *VirtualFileDate*, and *VirtualFileName*. Note: [VirtualFileDateFormat](#VirtualFileDateFormat) must be set to a format that includes the necessary level of accuracy.

*Destination* should be set to the SFID of the remote host.

*Originator* should be set to the SFID of the local system. In the case that the component is being used as part of a gateway process to forward traffic to another OFTP host this may be set to the SFID of that host instead.

*Creator* should be set to the SFID of the local system.

*Signature* is only applicable if the application is acting as a routing application. In all other cases this should be set to empty string. In the case where the application is acting as a routing application the end response is being forwarded to another entity for processing. The *Signature* should be set to the value received in the [EndResponse](#endresponse-event-oftpclient-component) event (if populated).

*ReasonCode* and *ReasonText* are used to specify error information. If *ReasonCode* is set to 0 the component will send an EERP. If *ReasonCode* is set to any non-zero value the component will send a NERP. Common values are:

|  |  |
| --- | --- |
| ReasonCode | ReasonText |
| 3 | User Code Not Known |
| 4 | Invalid Password |
| 9 | Unspecified Reason |
| 11 | Invalid FileName |
| 12 | Invalid Destination |
| 13 | Invalid Origin |
| 14 | Invalid Storage Record Format |
| 15 | Maximum Record Length Not Supported |
| 16 | File Size Too Big |
| 20 | Invalid Record Count |
| 21 | Invalid Byte Count |
| 22 | Access Method Failure |
| 23 | Duplicate File |
| 24 | File Direction Refused |
| 25 | Cipher Suite Not Supported |
| 26 | Encrypted File Not Allowed |
| 27 | Unencrypted File Not Allowed |
| 28 | Compression Not Allowed |
| 29 | Signed File Not Allowed |
| 30 | Unsigned File Not Allowed |
| 31 | File Signature Not Valid |
| 32 | File Decompression Failed |
| 33 | File Decryption Failed |
| 34 | File Processing Failed |
| 35 | Not Delivered To Recipient |
| 36 | Not Acknowledged By Recipient |
| 50 | Transmission Stopped By The Operator |
| 90 | File Size Incompatible With Recipient's Protocol Version |
| 99 | Unspecified Reason |

# SendFile Method ([OFTPClient](#oftpclient-component) Component)

Send the specified file to the server.

## Syntax

*Delphi Syntax*

```text
procedure SendFile(LocalFile: String; VirtualFileName: String);
```

## Remarks

This method connects to the server, and uploads the specified file to the server. The *LocalFile* parameter contains the path and name of the file to send to the server. The *VirtualFileName* parameter contains the virtual file name of the file being sent. If this parameter is left as an empty string, the component will use the filename contained in the *LocalFile* parameter by default.

Note: When SetUploadStream has been called with a valid input stream, the data will be uploaded from there instead of the *LocalFile*.

# ValidateCert Method ([OFTPClient](#oftpclient-component) Component)

Validates the certificate with private key.

## Syntax

*Delphi Syntax*

```text
function ValidateCert(): Boolean;
```

## Remarks

This method optionally validates the certificate specified by [Certificate](#certificate-property-oftpclient-component). It is not required to validate the certificate from a technical perspective, but may be desired to ensure the recipient's certificate is valid and issued by a trusted authority.

Before calling this method call [ImportTrustedCerts](#importtrustedcerts-method-oftpclient-component) to load the trusted certification information.

When this method is called the component:

- Validates the certificate has not expired
- Validates the certificate was issued by a CA in the [TrustedCerts](#trustedcerts-property-oftpclient-component) collection. If the certificate is self-signed this step is skipped.
- Validates the certificate has not been revoked. Note that the revocation check will only make use of the CRL distribution point identified in the certificate's extension. If the certificate does not contain a CRL distribution point extension this step is skipped.

# ValidateRecipientCert Method ([OFTPClient](#oftpclient-component) Component)

Validates the recipient certificate.

## Syntax

*Delphi Syntax*

```text
function ValidateRecipientCert(): Boolean;
```

## Remarks

This method optionally validates the certificate specified by [RecipientCert](#recipientcert-property-oftpclient-component). It is not required to validate the certificate from a technical perspective, but may be desired to ensure the recipient's certificate is valid and issued by a trusted authority.

Before calling this method call [ImportTrustedCerts](#importtrustedcerts-method-oftpclient-component) to load the trusted certification information.

When this method is called the component:

- Validates the certificate has not expired
- Validates the certificate was issued by a CA in the [TrustedCerts](#trustedcerts-property-oftpclient-component) collection. If the certificate is self-signed this step is skipped.
- Validates the certificate has not been revoked. Note that the revocation check will only make use of the CRL distribution point identified in the certificate's extension. If the certificate does not contain a CRL distribution point extension this step is skipped.

# AcceptFile Event ([OFTPClient](#oftpclient-component) Component)

Fired when the client receives a file.

## Syntax

*Delphi Syntax*

```text
type TAcceptFileEvent = procedure (
  Sender: TObject;
  const VirtualFileName: String;
  const VirtualFileDate: String;
  const Destination: String;
  const Originator: String;
  var Accept: Boolean;
  var FileName: String;
  var Overwrite: Boolean;
  var ErrorCode: Integer;
  var ErrorDescription: String
) of Object;
property OnAcceptFile: TAcceptFileEvent read FOnAcceptFile write FOnAcceptFile;
```

## Remarks

This event controls the behavior when the client receives a file.

*VirtualFileName* holds the name of the file being received.

*VirtualFileDate* holds the date associated with the file in the format specified by [VirtualFileDateFormat](#VirtualFileDateFormat). The default value is "MM/dd/yyyy HH:mm:ss".

*Destination* identifies the receiver (SFID) code in the send file request. If the file was intended for this server this will match the value in [ServerSFIDCode](#serversfidcode-property-oftpclient-component)

*Originator* identifies the sender (SFID) code in the send file request.

*Accept* is true by default, and must be set to False in order to reject the file.

*Filename* will be populated with the full path and filename that will be written. It may be changed within this event to specify a new location. The Filename is determined by combining the path specified in [DownloadDirectory](#@@OFTPClient_Connections@@_f_DownloadDirectory) and the name received from the client.

*Overwrite* is false by default, but may be set to true to overwrite existing files on disk.

*ErrorCode* controls the error returned to the client when *Accept* is set to False. If this is not set the component will use a value of 99 to indicate a general error.

*ErrorDescription* may also be set to include an error message. If this is not set the component will automatically include an error message based on the *ErrorCode* specified. Common error codes and their corresponding error messages are listed below.

|  |  |
| --- | --- |
| ErrorCode | ErrorMessage |
| 1 | Invalid filename. |
| 2 | Invalid destination. |

# CertificateReceived Event ([OFTPClient](#oftpclient-component) Component)

Fired when a certificate is received from the remote host.

## Syntax

*Delphi Syntax*

```text
type TCertificateReceivedEvent = procedure (
  Sender: TObject;
  const CertificateFileName: String;
  CertificateExchangeType: Integer
) of Object;
property OnCertificateReceived: TCertificateReceivedEvent read FOnCertificateReceived write FOnCertificateReceived;
```

## Remarks

This event provides information about the certificate file that was sent by the remote host.

When the remote host sends a certificate using the Certificate Exchange feature of OFTP 2.0, this event provides information about it. The certificate file will be written to the [DownloadDirectory](#downloaddirectory-property-oftpclient-component). After the file is written to [DownloadDirectory](#downloaddirectory-property-oftpclient-component) this event will fire.

The *CertificateFilename* parameter holds the filename of the received certificate.

The *CertificateExchangeType* parameter identifies the type of request associated with the certificate. Possible values are:

|  |  |
| --- | --- |
| 0 | Request: The component received a certificate and request from the remote host. Respond using the [ExchangeCertificate](#exchangecertificate-method-oftpclient-component) method using a CertificateExchangeType of 3 (Deliver). The response may be in a separate session. |
| 1 | Replace: The component received a certificate from the remote host. No response is expected. The certificate received here invalidates any previously stored certificates for this configuration. |
| 2 | Deliver: The component received a certificate from the remote host. This is either a response to a certificate request, or a new additional certificates from the remote host. This will not invalidate previous certificates stored for this configuration. |

# EndResponse Event ([OFTPClient](#oftpclient-component) Component)

Fired every time an end response is received from the server.

## Syntax

*Delphi Syntax*

```text
type TEndResponseEvent = procedure (
  Sender: TObject;
  const VirtualFileName: String;
  const VirtualFileDate: String;
  const Destination: String;
  const Originator: String;
  const Creator: String;
  ReasonCode: Integer;
  const ReasonText: String;
  var FileHash: String;
  const Signature: String;
  Direction: Integer
) of Object;
property OnEndResponse: TEndResponseEvent read FOnEndResponse write FOnEndResponse;
```

## Remarks

This event contains information received from an either an End-To-End Response or a Negative End Response received from the server.

An End-To-End Response will not contain values for the *ReasonCode*, *ReasonText*, or *Creator* parameters.

*VirtualFileName* specifies the name of the file.

*VirtualFileDate* holds the VirtualFileDate value in the format specified by [VirtualFileDateFormat](#VirtualFileDateFormat). The default value is "MM/dd/yyyy HH:mm:ss".

*Destination* is the SFID of the destination system (this component).

*Originator* identifies the system that originated the end response. This is typically the same as *Creator* and holds the remote system's SFID.

*Creator* is the SFID of the remote system.

*Direction* specifies whether the end response is being received or sent. Possible values are:

|  |  |
| --- | --- |
| 0 | Received |
| 1 | Sent |

 By default the component will only fire this event for received end responses. To configure the component to fire the event for both send and received end responses set [FireEndResponseOnSend](#FireEndResponseOnSend) to True.

*FileHash* is populated if the OFTP Version is 2.0 and a signed receipt was originally requested. FileHash may also be specified with the expected value in the case where an asynchronous EndResponse is received. The expected value may be obtained from the [EndTransfer](#endtransfer-event-oftpclient-component) event when initially sending the file.

*Signature* is only applicable when the OFTP version is 2.0 and the application is acting as a routing application where the end response will be forwarded on to another entity. In this case *Signature* will be populated if the end response is signed. This should be stored and supplied when forwarding the response with the [SendEndResponse](#sendendresponse-method-oftpclient-component) method.

*ReasonCode* and *ReasonText* identify the error if a Negative End Response (NERP) was received. A value of 0 indicates there was no an error and the response is an End-To-End Response (EERP). Common values are:

|  |  |
| --- | --- |
| ReasonCode | ReasonText |
| 3 | User Code Not Known |
| 4 | Invalid Password |
| 9 | Unspecified Reason |
| 11 | Invalid FileName |

# EndTransfer Event ([OFTPClient](#oftpclient-component) Component)

Fired when a file finishes transferring.

## Syntax

*Delphi Syntax*

```text
type TEndTransferEvent = procedure (
  Sender: TObject;
  Direction: Integer;
  const LocalFile: String;
  const VirtualFileName: String;
  const VirtualFileDate: String;
  const Destination: String;
  const Originator: String;
  ReasonCode: Integer;
  const ReasonText: String;
  FileSize: Int64;
  const FileHash: String;
  var SendEndResponse: Boolean
) of Object;
property OnEndTransfer: TEndTransferEvent read FOnEndTransfer write FOnEndTransfer;
```

## Remarks

The EndTransfer event is fired when a file is sent or received by the component.

The *FileSize* parameter gives the size of the file that was sent or received.

The *Direction* parameter shows whether the client or the server is sending the data.

|  |  |
| --- | --- |
| 0 (Client) | The file originated from the client. |
| 1 (Server) | The file originated from the server. |

*VirtualFileName* holds the filename.

*VirtualFileDate* holds the date associated with the file in the format specified by [VirtualFileDateFormat](#VirtualFileDateFormat). The default value is "MM/dd/yyyy HH:mm:ss".

*Originator* identifies the sender (SFID) code in the send file request.

*Destination* identifies the receiver (SFID) code in the send file request.

*SendEndResponse* indicates whether the EERP/NERP for this request should be sent synchronously or asynchronously. When this parameter is True (default) the component will automatically respond with an EERP/NERP synchronously. To respond asynchronously set this parameter to False. You may then use the [SendEndResponse](#sendendresponse-method-oftpclient-component) method to send the response at a later time. See [SendEndResponse](#sendendresponse-method-oftpclient-component) for more details. Note: [VirtualFileDateFormat](#VirtualFileDateFormat) must be set to a format that includes the necessary level of accuracy.

*FileHash* holds the hash of the file being transmitted. This is only applicable when the OFTP version is 2.0 and the sender requested a signed receipt. When receiving files this value should be saved if you wish to respond asynchronously using [SendEndResponse](#sendendresponse-method-oftpclient-component). See [SendEndResponse](#sendendresponse-method-oftpclient-component) for more details.

*LocalFile* holds the full path to the file that will be written.

*ReasonCode* and *ReasonText* identify the error if a Negative End Response (NERP) was received. A value of 0 indicates there was no an error and the response is an End-To-End Response (EERP). Common values are:

## Remarks

When connecting through a firewall, this type is used to specify different properties of the firewall, such as the firewall [Host](#Firewall_f_Host) and the [FirewallType](#Firewall_f_FirewallType).

The following fields are available:

- [AutoDetect](#Firewall_f_AutoDetect)

- [FirewallType](#Firewall_f_FirewallType)

- [Host](#Firewall_f_Host)

- [Password](#Firewall_f_Password)

- [Port](#Firewall_f_Port)

- [User](#Firewall_f_User)

## Fields

 **AutoDetect** *Boolean*
*Default Value: False*

Whether to automatically detect and use firewall system settings, if available.

 **FirewallType** *TibeFirewallTypes*
*Default Value: 0*

The type of firewall to connect through. The applicable values are as follows:

|  |  |
| --- | --- |
| fwNone (0) | No firewall (default setting). |
| fwTunnel (1) | Connect through a tunneling proxy. [Port](#Firewall_f_Port) is set to 80. |
| fwSOCKS4 (2) | Connect through a SOCKS4 Proxy. [Port](#Firewall_f_Port) is set to 1080. |
| fwSOCKS5 (3) | Connect through a SOCKS5 Proxy. [Port](#Firewall_f_Port) is set to 1080. |
| fwSOCKS4A (10) | Connect through a SOCKS4A Proxy. [Port](#Firewall_f_Port) is set to 1080. |

 **Host** *String*
*Default Value: ""*

The name or IP address of the firewall (optional). If a [Host](#Firewall_f_Host) is given, the requested connections will be authenticated through the specified firewall when connecting.

If this property is set to a Domain Name, a DNS request is initiated. Upon successful termination of the request, this property is set to the corresponding address. If the search is not successful, the component raises an exception.

 **Password** *String*
*Default Value: ""*

A password if authentication is to be used when connecting through the firewall. If [Host](#Firewall_f_Host) is specified, the [User](#Firewall_f_User) and [Password](#Firewall_f_Password) properties are used to connect and authenticate to the given firewall. If the authentication fails, the component raises an exception.

 **Port** *Integer*
*Default Value: 0*

The Transmission Control Protocol (TCP) port for the firewall [Host](#Firewall_f_Host). See the description of the [Host](#Firewall_f_Host) property for details.

NOTE: This property is set automatically when [FirewallType](#Firewall_f_FirewallType) is set to a valid value. See the description of the [FirewallType](#Firewall_f_FirewallType) property for details.

 **User** *String*
*Default Value: ""*

A username if authentication is to be used when connecting through a firewall. If [Host](#Firewall_f_Host) is specified, this property and the [Password](#Firewall_f_Password) property are used to connect and authenticate to the given [Firewall](#firewall-type). If the authentication fails, the component raises an exception.

# Config Settings ([OFTPClient](#oftpclient-component) Component)

 The component 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 component, access to these *internal properties* is provided through the [Config](#config-method-oftpclient-component) method.

### OFTPClient Config Settings

**AcceptAnySFIDCode**: Indicates that all SFID codes are acceptable.This setting controls whether the component checks the SFID codes when receiving files. When set to False (Default) and a file is received the component will check the client and server SFID codes sent by the server against the values specified in [ClientSFIDCode](#clientsfidcode-property-oftpclient-component) and [ServerSFIDCode](#serversfidcode-property-oftpclient-component). If they do not match an error is returned. In some situations it is necessary to consider any SFID code valid. To disable checking the SFID codes sent by the server set this to True.

**AllowRetry**: Whether to send a retry indicator when rejecting a file.When the server sends a file and it is rejected for any reason, if this setting is set to True the component will send a retry indicator value to the server to specify the file may be retried later.

When set to False (default) the component will send a value indicating the server should not retry the send operation.

**CertificateType**: Specifies the type of certificate being supplied.By default the component will use the certificate set in the [Certificate](#certificate-property-oftpclient-component) property for all operations that require a certificate. This setting allows for different certificates to be set for specific operations. First, specify the CertificateType via this setting and then set the [Certificate](#certificate-property-oftpclient-component) property. For instance:

```text
component.Config("CertificateType=3");
component.Certificate = mySigningCertificate;
```

 Possible values are:

|  |  |
| --- | --- |
| 0 (default) | All Operations |
| 1 | Session Authentication |
| 2 | Decryption |
| 3 | Signing |
| 4 | Receipt Signing |

**ConnectionType**: Specifies the type of connection that will be created.Use the [ConnectionType](#ConnectionType) setting to tell the component which type of connection to create. The default value is 0 (Both) in which the component can both send and receive files. However you can limit the component to only be able to send or receive files by specifying a value of 1 (Send Only) or 2 (Receive Only). Valid values are:

|  |  |
| --- | --- |
| 0 | Both (Default) |
| 1 | Send Only |
| 2 | Receive Only |

**CreditCount**: Specifies the credit value.This setting defines the maximum credit value to be sent in the initial connection (SSID command). The default value is 99 and the maximum value is 999. When connecting, the server will also indicate the value it wishes to use for the credit count. The smaller of the two values will be used. This setting may be queried after connecting to determine the negotiated value.

**DeleteOnError**: Whether received files are deleted when there is an error during processing.By default this value is True. When set to False and receiving a file, if the file is encrypted, signed, or compressed the file will be decrypted, verified, or decompressed. If there is an error during processing the original unprocessed file will be placed in [DownloadDirectory](#downloaddirectory-property-oftpclient-component). In that case you may choose what to do with the file based on the error reported during processing.

When this is set to True (default) and there is an error during processing the original unprocessed file will be deleted and no files will be placed in [DownloadDirectory](#downloaddirectory-property-oftpclient-component).

**DisconnectAfterEndSession**: Determines if the connection is closed immediately after ending the session.By default when [Logoff](#logoff-method-oftpclient-component) is called the component will close the TCP connection after ending the session (the ESID command is sent). To let the other side close the connection after it has received the end session command (ESID), set this to False.

**EnforceProtocolVersion**: Requires the server to support the same OFTP version.This settings controls the behavior when the server's OFTP version is different from the requested version. During the logon process the component will supply its OFTP [Version](#version-property-oftpclient-component) to the server. The server will respond with the OFTP version it is using for the connection. If the version is not the same, the action of the component depends on this setting.

When set to True, if the server's OFTP version does not match the client's [Version](#version-property-oftpclient-component), the component raises an exception. When set to False (default), if the server's OFTP version does not match the client's [Version](#version-property-oftpclient-component), the component will use the lowest mutually supported version.

**ExchangeBufferSize**: Specifies the data exchange buffer size in bytes.This setting defines the data exchange buffer size to be sent in the initial connection (SSID command) in bytes. The default value is 2048. When connecting, the server will also indicate the value it wishes to use for the data exchange buffer size. The smaller of the two values will be used. This setting may be queried after connecting to determine the negotiated value.

**ExchangeCertStoreType**: Specifies the store type when loading a certificate to be exchanged.This specifies the certificate store type when loading a certificate that will be sent to the remote party. This is only applicable when calling [ExchangeCertificate](#exchangecertificate-method-oftpclient-component). The default value is "8" which indicates the certificate will be loaded from a file on disk. When the certificate is not in a .cer format or is located in the Windows certificate store this setting should be set to the appropriate value before calling [ExchangeCertificate](#exchangecertificate-method-oftpclient-component).

For a list of possible values please see [CertStoreType](#OFTPClient_p_CertStoreType). Also see [ExchangeCertSubject](#ExchangeCertSubject).

**ExchangeCertSubject**: The subject of the certificate being exchanged.This specifies the subject of the certificate being exchanged. This will be used to load the appropriate certificate when [ExchangeCertificate](#exchangecertificate-method-oftpclient-component) is called. This is used in conjunction with [ExchangeCertStoreType](#ExchangeCertStoreType) and is only necessary when loading a certificate from a store that may hold more than one certificate (such as a Windows certificate store).

**FailOnUntrustedCert**: Whether or not to throw an exception when untrusted certificates are used.When [TrustedCerts](#trustedcerts-property-oftpclient-component) is populated the component will validate that loaded certificates were issued by a trusted CA in [TrustedCerts](#trustedcerts-property-oftpclient-component). This setting controls the behavior when an untrusted certificate is found. By default this value is True and the component will throw an exception. If this is set to False the component will fire the [Error](#error-event-oftpclient-component) event but the error will not be fatal and the operation will be allowed to continue.

**FileDescription**: Additional description information sent with the file.When sending a file this setting may be set to specify additional information. There is no restriction on the type of data supplied here. It may be set to a longer filename, or simply additional text data that you wish to pass to the receiver. The data supplied will be UTF-8 encoded by the component. The maximum length is 999 bytes (after UTF-8 encoding).

**FileHashAlgorithm**: The hash algorithm to use when sending a file.The file hash algorithm specified in this setting is used to calculate the hash sent along with an outgoing file. Possible values are:

|  |  |
| --- | --- |
| 0 | sha1 |
| 1 | sha256 (Default) |
| 2 | sha512 |

**FireEndResponseOnSend**: Determines if the EndResponse event is fired for outgoing EERP and NERPs.If set to True (default) the component will fire the [EndResponse](#endresponse-event-oftpclient-component) event for both sent and received end responses. If set to False the [EndResponse](#endresponse-event-oftpclient-component) event will fire only for received (incoming) end responses. The *Direction* parameter of [EndResponse](#endresponse-event-oftpclient-component) determines if the end response is being sent or received. The default value is True.

**FollowRedirects**: Determines behavior when importing trusted certificates and a HTTP redirect is returned.When [TrustedCertsData](#TrustedCertsData) holds a URL and [ImportTrustedCerts](#importtrustedcerts-method-oftpclient-component) is called the component makes a HTTP request to obtain the trusted certificates. If the server returns a HTTP redirect this setting specifies how the component will handle it. Possible values are:

|  |  |
| --- | --- |
| 0 (default) | Never follow redirects. An exception will be thrown. |
| 1 | Always follow redirects. The redirect will be automatically followed. |
| 2 | Follow same scheme redirects. Follow the redirect if it matches the same scheme (http:// or https://). |

**FriendlyLogFormat**: Determines if a more friendly format is applied to PITrail event out.This setting effects the content of the Data parameter of the [PITrail](#pitrail-event-oftpclient-component) event. By default this setting is true and a format designed to be more easily read is used. If set to false the Data parameter will hold the raw unformatted protocol level content.

**LogLevel**: The level of information to log.This setting specifies the level of detail that is logged to the [Log](#log-event-oftpclient-component) event. Possible values are:

|  |  |
| --- | --- |
| 0 (None) | No messages are logged. |
| 1 (Info - Default) | Informational events such as OFTP commands which are sent and received. |
| 2 (Verbose) | Detailed data such as individual packet information is logged. |
| 3 (Debug) | Debug data including all relevant sent and received bytes are logged. |

**MaskSensitiveData**: Masks passwords in logs.The default value is True. When set to True, the component will mask passwords that otherwise would appear in its logs.

**ReceiptHashAlgorithm**: The receipt hash algorithm to request when sending a file.The receipt hash algorithm specified in this setting is sent to the receiving party when a file is sent, and the receiving party should use this value when calculating the hash returned in the EERP or NERP receipt. Possible values are:

|  |  |
| --- | --- |
| 0 | sha1 (Default) |
| 1 | sha256 |
| 2 | sha512 |

**ReceivedFileDateTime**: The datetime of the file being received.This setting may be queried to obtain the datetime of the received file.

**ReceivedFileDescription**: Additional description information received with the file.Query this setting after receiving a file to obtain any additional information provided by the server. The data will be UTF-8 decoded by the component.

**ReceivedFileEncryptionAlg**: The encryption algorithm used for the file being received.This setting may be queried to obtain the encryption algorithm used for encryption of the file being received. The possible values are:

|  |  |
| --- | --- |
| 0 | 3DES (Triple Data Encryption Standard). |
| 1 | AES (Advanced Encryption Standard CBC mode with a 256-bit key). |

**ReceivedFileName**: Returns the name of the received file.This setting may be queried inside the [EndTransfer](#endtransfer-event-oftpclient-component) event to obtain the name of the received file on disk. This includes the full path to the file on disk.

**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%"

 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%"

**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%"

 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%"

**RecipientCertificateType**: Specifies the type of recipient certificate being supplied.By default the component will use the certificate set in the [RecipientCert](#recipientcert-property-oftpclient-component) property for all operations that require a certificate. This setting allows for different certificates to be set for specific operations. First, specify the RecipientCertificateType via this setting and then set the [RecipientCert](#recipientcert-property-oftpclient-component) property. For instance:

```text
component.Config("RecipientCertificateType=3");
component.RecipientCert = mySignatureVerificationCertificate;
```

 Possible values are:

|  |  |
| --- | --- |
| 0 (default) | All Operations |
| 1 | Session Authentication |
| 2 | Encryption |
| 3 | Signature Verification |
| 4 | Receipt Signature Verification |

**Retry**: Indicates whether the recipient allows the send to be retried.When sending files the recipient may reject the file for a number of reasons. The recipient may indicate that the operation can be re-attempted later. Query this setting after a send attempt was rejected to determine if the recipient allows retries. This setting will return either True or False.

**SendCDAfterEFPA**: Specifies whether a CD is always sent after receiving an EFPA.When sending a file the recipient will respond with an EFPA once the file is received. Within this response is an indicator which tells the sender whether to issue a CD (Change Direction) command. The indicator is read by the component and a CD command is sent if requested. If a CD is not requested then no CD is sent.

When set to True, this overrides the default behavior and will always send a CD command regardless of whether the indicator is set in the EFPA.

This should only be set if there is a specific reason to do so. In most cases it is not necessary.

**TempPath**: The path of a directory where temporary files will be created.Under certain conditions, the component will create temporary files before processing a file. The location of the temporary files is determined by this setting. Temporary files are created if any of the following conditions are true.

- [Compress](#compress-property-oftpclient-component) is true
- [VirtualFileSecurityLevel](#virtualfilesecuritylevel-property-oftpclient-component) is set to slEncrypted
- [VirtualFileSecurityLevel](#virtualfilesecuritylevel-property-oftpclient-component) is set to slSigned
- [VirtualFileSecurityLevel](#virtualfilesecuritylevel-property-oftpclient-component) is set to slEncryptedAndSigned

Note that [VirtualFileSecurityLevel](#virtualfilesecuritylevel-property-oftpclient-component) is only applicable when [Version](#version-property-oftpclient-component) is set to oftpVer20.

**TrustedCertsData**: Specifies the source to be used when importing trusted certificates.When [ImportTrustedCerts](#importtrustedcerts-method-oftpclient-component) is called it will attempt to import certificates from the location specified here. By default this is the URL provided by Odette (http://www.odette.org/TSL/TSL_OFTP2.XML). This is the live list of CA certificates hosted by Odette. This may also be set to an absolute file path to load certificates from an offline source, or a string value containing the trusted CA certificates.

**VirtualFileDateFormat**: The DateTime format of received files.This setting specifies the DateTime format used by the component when reporting the VirtualFileDate of received files. The default format is "MM/dd/yyyy HH:mm:ss".

When using OFTP v2.0 If the component is configured to respond to EERP and NERP messages asynchronously this should be set to the value "yyyyMMddHHmmssffff" or a similar format that includes the same level of accuracy. This is required to ensure that when calling [SendEndResponse](#sendendresponse-method-oftpclient-component) the value saved from within the [EndTransfer](#endtransfer-event-oftpclient-component) event has the necessary data when sending a response.

### 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 component 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.

**MaskSensitiveData**: 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 *True*.

**UseFIPSCompliantAPI**: Tells the component whether or not to use FIPS certified APIs.When set to *True*, the component will utilize the underlying operating system's certified APIs. Java editions, regardless of OS, utilize Bouncy Castle Federal Information Processing Standards (FIPS), while all other Windows editions make use of Microsoft security libraries.

FIPS mode can be enabled by setting the *UseFIPSCompliantAPI* configuration setting to *True*. This is a static setting that applies to all instances of all components of the toolkit within the process. It is recommended to enable or disable this setting once before the component has been used to establish a connection. Enabling FIPS while an instance of the component is active and connected may result in unexpected behavior.

For more details, please see the [FIPS 140-2 Compliance](https://www.nsoftware.com/kb/articles/fips.rst) article.

NOTE: This setting is applicable only on Windows.

NOTE: Enabling FIPS compliance requires a special license; please contact [sales@nsoftware.com](mailto:sales@nsoftware.com) for details.

**UseInternalSecurityAPI**: Whether or not to use the system security libraries or an internal implementation. When set to *False*, the component will use the system security libraries by default to perform cryptographic functions where applicable.

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

 This setting is set to *False* by default on all platforms.
