OFTP Connector

The OFTP Component adds OFTP send and receive capabilities to your MuleSoft.

Remarks

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

OFTP Receive Connector

The OFTP Receive Connector 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 connector will connect to the OFTP server and download all files in the server's outgoing queue, and submit these to the Mule Project as individual messages.

Download Files Example

Drag and drop the OFTP Receive Connector into the source position of a flow. If you want to download from a server using OFTP version 1.2 without encryption, most of the settings can be left at their defaults.

To configure the connection, set the ClientSSIDCode, ClientSFIDCode, and ClientPassword properties to your own information, and set the ServerSSIDCode, ServerSFIDCode, and ServerPassword properties to the server's information. Then set the OFTPServer and OFTPPort properties to the server's address.

When the connector is scheduled to run, it will connect to the server, download any available files, and submit each one to the flow as a message.

OFTP Send Connector

The OFTP Send Connector 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 connector 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 set to a value containing an empty string, a temporary filename will be used.

Upload Files Example

Drag and drop the OFTP Send Connector into the flow. If you want to upload to a server using OFTP version 1.2 without encryption, most of the settings can be left at their defaults.

Set VirtualFileName and VirtualFileDate to set the propertys of the uploaded file. By default, the VirtualFileName will be set to "#[attributes.filename], which would contain the local name of a file passed to the connector by a File connector

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 Connector)

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 connector 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 connector 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.

Note: You may also set the Accept Any field to Yes without opening the certificate selection dialog to force the connector 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 connector to report the server's credentials to Location.

SSLCert Property (OFTP Connector)

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.

Private key certificates may be loaded from the registry, from files in PKCS#12 format, or from a PEM file format.

TempPath Property (OFTP Connector)

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

Once the file is submitted, the connector will handle closing the file stream and deleting the temporary file. However, if the connector 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. Note: by default, this property is empty and the connector 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 Connector)

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

If Timeout expires, and the operation is not yet complete, the connector 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 connector may be changed to absolute timeouts, i.e. the connector 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).

UseSSL Property (OFTP Connector)

Use SSL to access the OFTPServer .

Data Type

Boolean

Default Value

false

Remarks

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

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

Version Property (OFTP Connector)

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 Connector)

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.

VirtualFileFormat Property (OFTP Connector)

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 connector 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 connector 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 Connector)

The virtual file name.

Data Type

String

Default Value

"#[attributes.fileName]"

Remarks

This is the virtual name of the file to be sent to the server. If set to a value that contains an empty string, the connector will create a temporary filename to use as the VirtualFileName.

This property is not available in the Receiver.

VirtualFileSecurityLevel Property (OFTP Connector)

The level of security for the outgoing file.

Data Type

Enumeration

Possible Values

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

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.

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.

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

AutoDetect
Boolean
Default Value: False

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

FirewallType
FirewallTypes
Default Value: 0

Determines the type of firewall to connect through. The applicable values are the following:


fwNone (0)	No firewall (default setting).
fwTunnel (1)	Connect through a tunneling proxy. Port is set to 80.
fwSOCKS4 (2)	Connect through a SOCKS4 Proxy. Port is set to 1080.
fwSOCKS5 (3)	Connect through a SOCKS5 Proxy. Port is set to 1080.

Host
String
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.

Config Settings (OFTP Connector)

The connector 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 connector, 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 connector 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 connector 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 connector 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 connector 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 connector 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 connector initiate connections (or accept in the case of server connectors) only through that interface.

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

By default, this config is set to false.

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

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

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

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