SFTP Control
Properties Methods Events Config Settings Errors
The SFTP control can be used to transfer files to and from SFTP servers using the SFTP Protocol.
Syntax
SFTP
Remarks
The SFTP control is the SSH-enabled equivalent of the IPWorks FTP control. The SSHHost and SSHPort properties specify the SSH server to use. The SSHUser and SSHPassword properties allow the client to authenticate itself with the server. The SSHServerAuthentication event and/or SSHAcceptServerHostKey property allow you to check the server identity. Finally, the SSHStatus event provides information about the SSH handshake.
The SFTP control implements a standard SSH File Transfer client.
The first step in using the control is specifying the SSHHost, SSHUser and SSHPassword. The file to upload to or download from is given by the RemoteFile property. The file to download to or upload from is specified by LocalFile. The current path in the server is specified by the RemotePath property.
If LocalFile is set to something other than an empty string, then files are received in LocalFile, otherwise the data is received through the Transfer event. StartTransfer and EndTransfer are fired at the beginning and end of transmission.
Directory listings are received through the DirList event.

Data Type
String
FilePermissions Property (SFTP Control)
A 32-bit integer containing the a POSIX-compatible file permission bitmask.
Syntax
sftpcontrol.FilePermissions[=integer]
Default Value
0
Remarks
A 32-bit integer containing the a POSIX-compatible file permission bitmask.
The bitmask should be interpreted as a decimal value of a series of octal digits. For example, an octal permission value of "100644" would be "33188" in base-10, and "40755" in octal would be "16877" in base-10.
The last three octal digits are the most significant and represent, in order, the file access capabilities of the file's owner, the owner's group and other users. Each of these octal digits is, on its own, a 3-bit bitmask with the following possible values:
1 (001) | Execute |
2 (010) | Write |
4 (100) | Read |
An octal permission digit of 7 would have all three values set and would mean that the file can be read, written and executed by that user class. For example, the octal permissions "100644" would have a value "6" for the owner, "4" for the group, and "4" for other users. This would be interpreted to mean that all users can read the file, no users can execute it and only the owner can write it. The permissions "40755" would mean that all users can read and execute the file, but only the owner can write it.
The previous octal digit is another bitmask with the following values:
1 (001) | Sticky Bit - retain the file in memory for performance |
2 (010) | Set GID - sets the group ID of the process to the file's group ID upon execution (only for executable files) |
4 (100) | Set UID - sets the user ID of the process to the file's user ID upon execution (only for executable files) |
The previous two octal digits are used together as a bitmask to determine the type of file. This bitmask has the following values:
01 (000001) | Named pipe |
02 (000010) | Character special |
04 (000100) | Directory |
06 (000110) | Block special |
10 (001000) | Regular |

Data Type
Integer
FilePermissionsOctal Property (SFTP Control)
An octal string containing the a POSIX-compatible file permission bitmask The bitmask should be interpreted as a series of octal digits.
Syntax
sftpcontrol.FilePermissionsOctal[=string]
Default Value
""
Remarks
An octal string containing the a POSIX-compatible file permission bitmask
The bitmask should be interpreted as a series of octal digits. For example, "100644" and "40755".
The last three octal digits are the most significant and represent, in order, the file access capabilities of the file's owner, the owner's group and other users. Each of these octal digits is, on its own, a 3-bit bitmask with the following possible values:
1 (001) | Execute |
2 (010) | Write |
4 (100) | Read |
An octal permission digit of 7 would have all three values set and would mean that the file can be read, written and executed by that user class. For example, the octal permissions "100644" would have a value "6" for the owner, "4" for the group, and "4" for other users. This would be interpreted to mean that all users can read the file, no users can execute it and only the owner can write it. The permissions "40755" would mean that all users can read and execute the file, but only the owner can write it.
The previous octal digit is another bitmask with the following values:
1 (001) | Sticky Bit - retain the file in memory for performance |
2 (010) | Set GID - sets the group ID of the process to the file's group ID upon execution (only for executable files) |
4 (100) | Set UID - sets the user ID of the process to the file's user ID upon execution (only for executable files) |
The previous two octal digits are used together as a bitmask to determine the type of file. This bitmask has the following values:
01 (000001) | Named pipe |
02 (000010) | Character special |
04 (000100) | Directory |
06 (000110) | Block special |
10 (001000) | Regular |
12 (001010) | Symbolic link |
14 (001100) | Socket |
For example, the octal file permissions "100644" would indicate a regular file and octal "40755" would indicate a directory.

Remarks
The LocalHost property contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.
In multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the control initiate connections (or accept in the case of server controls) only through that interface.
If the control is connected, the LocalHost property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multi-homed hosts (machines with more than one IP interface).
NOTE: LocalHost is not persistent. You must always set it in code, and never in the property window.
Data Type
String
LocalPort Property (SFTP Control)
The TCP port in the local host where the control binds.
Syntax
sftpcontrol.LocalPort[=integer]
Default Value
0
Remarks
This property must be set before a connection is attempted. It instructs the control to bind to a specific port (or communication endpoint) in the local machine.
Setting this property to 0 (default) enables the system to choose an open port at random. The chosen port will be returned by the LocalPort property after the connection is established.
LocalPort cannot be changed once a connection is made. Any attempt to set this property when a connection is active will generate an error.
This property is useful when trying to connect to services that require a trusted port in the client side.

SFTPControl.Download()
SFTPControl.Localfile = "C:\localfile2.txt"
SFTPControl.RemoteFile = "folder/remotefile2.txt"
SFTPControl.Download()
Note: This property will also act as a file mask when performing ListDirectory.
Example (Using RemoteFile as a file mask):
SFTPControl.RemoteFile = "*.txt"
SFTPControl.ListDirectory()
The following special characters are supported for pattern matching:
? | Any single character. |
* | Any characters or no characters (e.g., C*t matches Cat, Cot, Coast, Ct). |
[,-] | A range of characters (e.g., [a-z], [a], [0-9], [0-9,a-d,f,r-z]). |
\ | The slash is ignored and exact matching is performed on the next character. |
If these characters need to be used as a literal in a pattern, then they must be escaped by surrounding them with brackets []. Note: "]" and "-" do not need to be escaped. See below for the escape sequences:
Character | Escape Sequence |
? | [?] |
* | [*] |
[ | [[] |
\ | [\] |
For example, to match the value [Something].txt, specify the pattern [[]Something].txt.
Data Type
String
RemotePath Property (SFTP Control)
The current path in the SFTP server.
Syntax
sftpcontrol.RemotePath[=string]
Default Value
""
Remarks
The RemotePath shows the current working directory on the SFTP server. It can also be used to change the working directory by setting it to an absolute directory path, or a relative path with respect to the existing value of RemotePath.
If the first two bytes of the new path are "..", then a change to one level above in the directory tree is performed.
Setting RemotePath causes the control to send the appropriate command to the remote server only if connected.
Example (Changing Directory)
sftp1.SSHLogon("sftp.server.net", 22);
sftp1.ChangeRemotePath("/home/user");
Note:It is recommended to use the ChangeRemotePath method instead of setting this property.
Data Type
String
SSHAcceptServerHostKeyEncoded Property (SFTP Control)
This is the certificate (PEM/base64 encoded).
Syntax
sftpcontrol.SSHAcceptServerHostKeyEncoded[=string]
Default Value
""
Remarks
This is the certificate (PEM/Base64 encoded). This property is used to assign a specific certificate. The SSHAcceptServerHostKeyStore and SSHAcceptServerHostKeySubject properties also may be used to specify a certificate.
When SSHAcceptServerHostKeyEncoded is set, a search is initiated in the current SSHAcceptServerHostKeyStore for the private key of the certificate. If the key is found, SSHAcceptServerHostKeySubject is updated to reflect the full subject of the selected certificate; otherwise, SSHAcceptServerHostKeySubject is set to an empty string.
To read or write binary data to the property, a Variant (Byte Array) version is provided in .SSHAcceptServerHostKeyEncodedB.
This property is not available at design time.
Data Type

Possible Values
amNone(0), amMultiFactor(1), amPassword(2), amPublicKey(3), amKeyboardInteractive(4), amGSSAPIWithMic(5), amCustom(6), amGSSAPIKeyex(7)
Default Value
2
Remarks
The SSH Authentication specification (RFC 4252) specifies multiple methods by which a user can be authenticated by an SSH server. When a call is made to SSHLogon, the control will connect to the SSH server and establish the security layer. After the connection has been secured, the client will send an authentication request to the SSHHost containing the SSHUser. The server will respond containing a list of methods by which that user may be authenticated.
The control will attempt to authenticate the user by one of those methods based on the value of SSHAuthMode and other property values supplied by the user. Currently, the control supports the following authentication methods:
amNone (0) | No authentication will be performed. The current SSHUser value is ignored, and the connection will be logged in as anonymous. |
amMultiFactor (1) | This allows the control to attempt a multi-step authentication process. The control will send authentication data to the server based on the list of methods allowed for the current user and the authentication property values supplied. The control will continue to send authentication data until the server acknowledges authentication success. If the server rejects an authentication step, the control fails with an error. |
amPassword (2) | The control will use the values of SSHUser and SSHPassword to authenticate the user. |
amPublicKey (3) | The control will use the values of SSHUser and the SSHCert* properties to authenticate the user. the SSHCert* properties must have a private key available for this authentication method to succeed. |
amKeyboardInteractive (4) | At the time of authentication, the control will fire the SSHKeyboardInteractive event containing instructions on how to complete the authentication step. (NOTE: amKeyboardInteractive is not supported in SSHTunnel). |
amGSSAPIWithMic (5) | This allows the control to attempt Kerberos authentication using the GSSAPI-WITH-MIC scheme. The client will try Kerberos authentication using the value of SSHUser (single sign-on), or if SSHPassword is specified as well, it will try Kerberos authentication with alternate credentials. This is currently supported only on Windows, unless using the Java edition, which also provides support for Linux and macOS. |
amCustom (6) | This allows the control caller to take over the authentication process completely. When amCustom is set, the control will fire the SSHCustomAuth event as necessary to complete the authentication process. |
amGSSAPIKeyex (7) | This allows the control to attempt Kerberos authentication using the GSSAPIKeyex scheme. The client will try Kerberos authentication using the value of SSHUser (single sign-on), or if SSHPassword is specified as well, it will try Kerberos authentication with alternate credentials. This is currently supported only on Windows, unless using the Java edition, which also provides support for Linux and macOS. |
Example (User/Password Auth):
Control.SSHAuthMode = SftpSSHAuthModes.amPassword
Control.SSHUser = "username"
Control.SSHPassword = "password"
Control.SSHLogon("server", 22)
Example (Public Key Auth):
Control.SSHAuthMode = SftpSSHAuthModes.amPublicKey
Control.SSHUser = "username"
Control.SSHCertStoreType = SSHCertStoreTypes.cstPFXFile;
Control.SSHCertStore = "cert.pfx";
Control.SSHCertStorePassword = "certpassword";
Control.SSHCertSubject = "*";
Control.SSHLogon("server", 22)
Data Type
Integer
SSHCertEncoded Property (SFTP Control)
This is the certificate (PEM/base64 encoded).
Syntax
sftpcontrol.SSHCertEncoded[=string]
Default Value
""
Remarks
This is the certificate (PEM/Base64 encoded). This property is used to assign a specific certificate. The SSHCertStore and SSHCertSubject properties also may be used to specify a certificate.
When SSHCertEncoded is set, a search is initiated in the current SSHCertStore for the private key of the certificate. If the key is found, SSHCertSubject is updated to reflect the full subject of the selected certificate; otherwise, SSHCertSubject is set to an empty string.
To read or write binary data to the property, a Variant (Byte Array) version is provided in .SSHCertEncodedB.
This property is not available at design time.
Data Type
Binary String
SSHCertStore Property (SFTP Control)
This is the name of the certificate store for the client certificate.
Syntax
sftpcontrol.SSHCertStore[=string]
Default Value
"MY"
Remarks
This is the name of the certificate store for the client certificate.
The SSHCertStoreType property denotes the type of the certificate store specified by SSHCertStore. If the store is password protected, specify the password in SSHCertStorePassword.
SSHCertStore is used in conjunction with the SSHCertSubject property to specify client certificates. If SSHCertStore has a value, and SSHCertSubject or SSHCertEncoded is set, a search for a certificate is initiated. Please see the SSHCertSubject property for details.
Designations of certificate stores are platform dependent.
The following designations are the most common User and Machine certificate stores in Windows:
MY | A certificate store holding personal certificates with their associated private keys. |
CA | Certifying authority certificates. |
ROOT | Root certificates. |
When the certificate store type is PFXFile, this property must be set to the name of the file. When the type is PFXBlob, the property must be set to the binary contents of a PFX file (i.e., PKCS#12 certificate store).
To read or write binary data to the property, a Variant (Byte Array) version is provided in .SSHCertStoreB.

Control.SSHCertStore = "cert.pfx";
Control.SSHCertStorePassword = "certpassword";
Control.SSHCertSubject = "*";
Control.SSHLogon("server", 22)
Data Type
String
StartByte Property (SFTP Control)
The offset in bytes at which to begin the Upload or Download.
Syntax
sftpcontrol.StartByte[=long64]
Default Value
0
Remarks
The StartByte property is used by the Upload and Download methods to determine at what offset to begin the transfer. This allows for resuming both uploads and downloads. The value of this property is reset to 0 after a successful transfer. StartByte is not valid for use with Append.
When downloading, this property can be used in conjunction with the TransferredDataLimit configuration setting in order to only download a specific range of data from the current RemoteFile.
Data Type
Long64
Timeout Property (SFTP Control)
A timeout for the control.
Syntax
sftpcontrol.Timeout[=integer]
Default Value
60
Remarks
If the Timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.
If Timeout is set to a positive value, the control will wait for the operation to complete before returning control.
The control will use DoEvents to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not "freeze" and remains responsive.
If Timeout expires, and the operation is not yet complete, the control 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 any amount of data is successfully sent or received.
The default value for the Timeout property is 60 seconds.
Data Type
Integer
Append Method (SFTP Control)
Append data from LocalFile to a remote file RemoteFile on an SFTP server.
Syntax
sftpcontrol.Append
Remarks
Similar to the Upload method but the local file specified by LocalFile is appended to RemoteFile on the server as opposed to replacing it as done by the Upload method. RemoteFile is either an absolute path on the server, or a path relative to RemotePath. The server will create a file with that name if it doesn't already exist (similar to Upload).
If there is no SSH session in place, one is automatically created by the component first.
ChangeRemotePath Method (SFTP Control)
Changes the current path on the server.
Syntax
sftpcontrol.ChangeRemotePath RemotePath
Remarks
This method changes the current path on the server to the specified RemotePath. When called, the control will issue a command to the server to change the directory. The RemotePath parameter may hold an absolute or relative path.
Absolute Paths
If the path begins with a / it is considered and absolute path and must specify the entire path from the root of the server. For instance:
component.ChangeRemotePath("/home/testuser/myfolder");
Relative Paths
If the path does not begin with a / it is considered a relative path and is resolved in relation to the current directory. For instance a value of myfolder will indicate a sub-folder of the current directory. The special value .. refers to the parent directory of the current path. For instance:
//Change to the 'myfolder' sub-directory
component.ChangeRemotePath("myfolder");
//Navigate up two levels and then into the 'another/folder' path.
component.ChangeRemotePath("../../another/folder");
CheckFileExists Method (SFTP Control)
Returns if the file specified by RemoteFile exists on the remote server.
Syntax
sftpcontrol.CheckFileExists
Remarks
This property returns if the file exists on the remote server. It returns if the file does not exist. You must specify the file you wish to check by setting the RemoteFile prior to calling this method.
If there is no session in place, the value of this property will always be .
Config Method (SFTP Control)
Sets or retrieves a configuration setting.
Syntax
sftpcontrol.Config ConfigurationString
Remarks
Config is a generic method available in every control. It is used to set and retrieve configuration settings for the control.
These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the control, access to these internal properties is provided through the Config method.
To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).
To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.
Connect Method (SFTP Control)
Connects to the SSH host without logging in.
Syntax
sftpcontrol.Connect
Remarks
This method establishes a connection with the SSHHost but does not log in. In most cases it is recommended to use the SSHLogon method which will both establish a connection and log in to the server.
This method may be useful in cases where it is desirable to separate the connection and logon operations, for instance confirming a host is available by first creating the connection.
CreateFile Method (SFTP Control)
Creates a file on the SFTP server.
Syntax
sftpcontrol.CreateFile FileName
Remarks
This method creates an empty file on the server with the name specified by the FileName parameter.
To upload a file with content use Upload instead.
DecodePacket Method (SFTP Control)
Decodes a hex-encoded SSH packet.
Syntax
sftpcontrol.DecodePacket EncodedPacket
Remarks
This method is used to decode an SSH packet created by EncodePacket.
Note: This method is only applicable for reading and creating SSH packets for use within the SSHCustomAuth event.
DeleteFile Method (SFTP Control)
Remove a file specified by FileName from an SFTP server.
Syntax
sftpcontrol.DeleteFile FileName
Remarks
The remote file or directory specified by FileName is deleted. FileName is either an absolute path on the server, or a path relative to RemotePath.
If there is no SSH session in place, one is automatically created by the component first.
Disconnect Method (SFTP Control)
This method disconnects from the server without first logging off.
Syntax
sftpcontrol.Disconnect
Remarks
This method immediately disconnects from the server without first logging off.
In most cases the SSHLogoff method should be used to logoff and disconnect from the server. Call the Disconnect method in cases where it is desirable to immediately disconnect without first logging off.
DoEvents Method (SFTP Control)
Processes events from the internal message queue.
Syntax
sftpcontrol.DoEvents
Remarks
When DoEvents is called, the control processes any available events. If no events are available, it waits for a preset period of time, and then returns.
Download Method (SFTP Control)
Download a RemoteFile from an SFTP server.
Syntax
sftpcontrol.Download
Remarks
The remote file specified by RemoteFile is downloaded to the local file specified by LocalFile, or it is retrieved through the Transfer event, if the LocalFile property is "" (empty string). RemoteFile is either an absolute path on the server, or a path relative to RemotePath.
If there is no SSH session in place, one is automatically created by the component first.
Example (Download a File)
SFTPControl.Localfile = "C:\localfile.txt"
SFTPControl.RemoteFile = "remotefile.txt"
SFTPControl.Download()
SFTPControl.Localfile = "C:\localfile2.txt"
SFTPControl.RemoteFile = "folder/remotefile2.txt"
SFTPControl.Download()
EncodePacket Method (SFTP Control)
Hex encodes an SSH packet.
Syntax
sftpcontrol.EncodePacket Packet
Remarks
This method is used to encode a raw SSH packet created by SetSSHParam.
Note: This method is only applicable for reading and creating SSH packets for use within the SSHCustomAuth event.
GetSSHParam Method (SFTP Control)
Used to read a field from an SSH packet's payload.
Syntax
sftpcontrol.GetSSHParam Payload, Field
Remarks
This method is used to read the value of a particular field from an SSH packet's payload. Payload should contain the full payload of a packet received by an event such as SSHChannelRequest. Field is the name of a field to be read out of the packet.
The following is a list of the names of well-known channel request field names and their encodings:
ChannelId (int32) | The id of the channel that received the packet. |

signal
Sends a signal to the remote process/service. The following field is available:
SignalName (string) | The name of the signal to be sent. |
If the packet type is not well known, Field should start with the special character "%" and contain a comma-separated list of field types as defined in SetSSHParam. For example, reading out the X11AuthProtocol of an x11-req payload, you can use "%s,f".
Note: the return value is a string encoded the same way as the FieldValue param in SetSSHParam.
Note: This method is only applicable for reading and creating SSH packets for use within the SSHCustomAuth event.
GetSSHParamBytes Method (SFTP Control)
Used to read a field from an SSH packet's payload.
Syntax
sftpcontrol.GetSSHParamBytes Payload, Field
Remarks
This method is the same as calling GetSSHParam, but returns raw bytes instead of strings.
Note: This method is only applicable for reading and creating SSH packets for use within the SSHCustomAuth event.
Interrupt Method (SFTP Control)
Interrupt the current method.
Syntax
sftpcontrol.Interrupt
Remarks
If there is no method in progress, Interrupt simply returns, doing nothing.
ListDirectory Method (SFTP Control)
List the current directory specified by RemotePath on an SFTP server.
Syntax
sftpcontrol.ListDirectory
Remarks
A listing is requested for the directory (or file mask) specified in RemoteFile. RemoteFile is either an absolute path on the server, or a path relative to RemotePath. The file listing is received through the DirList event.
If there is no SSH session in place, one is automatically created by the component first.
MakeDirectory Method (SFTP Control)
Create a directory on an SFTP server.
Syntax
sftpcontrol.MakeDirectory NewDir
Remarks
A directory with path specified by NewDir is created on the SFTP server. NewDir is either an absolute path on the server, or a path relative to RemotePath.
If there is no SSH session in place, one is automatically created by the component first.
QueryFileAttributes Method (SFTP Control)
Queries the server for the attributes of RemoteFile .
Syntax
sftpcontrol.QueryFileAttributes
Remarks
This method queries the server for attributes of RemoteFile. After calling this method FileAttributes will be populated with the values returned by the server.
To update attributes modify the desired values in FileAttributes and call UpdateFileAttributes.
QueueFile Method (SFTP Control)
Adds a file to the transfer queue.
Syntax
sftpcontrol.QueueFile LocalFile, RemoteFile
Remarks
This method adds a file to the queue of files that will be transferred.
It is not required to use this method, however this extends the ability of the control to allow for multiple simultaneous file transfers.
To simply transfer a file without using this method you need only set LocalFile, RemoteFile, and call Upload or Download as appropriate. This method allows you to instead queue multiple files before beginning a transfer.
When a file is queued it will not be transferred until the Upload or Download method is called. If multiple files are queued the files will be transferred simultaneously. The SimultaneousTransferLimit setting controls the maximum number of simultaneous transfers.
The Upload or Download method will not return until the Queue has been completely processed. This method may be called from within events in order to add additional files to the Queue before processing is complete.
To clear the queue call ResetQueue. This will not affect current transfers.
To cancel and individual file transfer set the Cancel parameter of the Transfer event to true. The rest of the queue will continue to process as normal.
The Interrupt method may be called to immediately stop all current transfers.
In the event of a file specific error the Error event will fire and the LocalFile and RemoteFile event parameters can be used to identify the file to which the error applies.
RemoveDirectory Method (SFTP Control)
Remove a directory specified by DirName from an SFTP server.
Syntax
sftpcontrol.RemoveDirectory DirName
Remarks
A directory with path specified by DirName is deleted on the SFTP server. DirName is either an absolute path on the server, or a path relative to RemotePath.
If there is no SSH session in place, one is automatically created by the component first.
RenameFile Method (SFTP Control)
Change the name of RemoteFile to NewName .
Syntax
sftpcontrol.RenameFile NewName
Remarks
The name of remote file or folder specified by RemoteFile is changed to NewName. RemoteFile and NewName are either absolute paths on the server, or a path relative to RemotePath.
If there is no SSH session in place, one is automatically created by the component first.
Reset Method (SFTP Control)
Reset the control.
Syntax
sftpcontrol.Reset
Remarks
This method will reset the control's properties to their default values.
ResetQueue Method (SFTP Control)
Resets the queue of files to be transferred.
Syntax
sftpcontrol.ResetQueue
Remarks
This method will remove all files from the transfer queue.
Calling this method will clear all files that were queued by QueueFile. Calling this method will not affect current transfers.
SetSSHParam Method (SFTP Control)
Used to write a field to the end of a payload.
Syntax
sftpcontrol.SetSSHParam Payload, FieldType, FieldValue
Remarks
This method is used to build the payload portion of an SSH packet to be sent later by a call to SendSSHPacket. Payload should contain the result of a previous call to SetSSHParam. FieldType is a string defining the type of field to be written to the packet. FieldValue should be the string representation of the field to be written.
The following is a list of supported field types and a description of how FieldValue should be encoded:
s | A plaintext string containing the default system encoding of the data. |
sb | A string containing the hex encoded data. (eg: "A1B23C") |
m | A variable-length large integer, encoded as a textual representation of the value ("1234"). |
i | A 32-bit integer, encoded as a textual representation of the value (eg: "1234"). |
l | A 64-bit integer, encoded as a textual representation of the value (eg: "1234"). |
b | A single byte, encoded as a textual representation of the value (eg: "123"). |
f | A boolean flag, encoded as a textual representation of the value (eg: 'true' or 'false') |
Note: integer values may be encoded in hexadecimal by prefixing "0x" to the beginning of the string, otherwise the value is assumed to be base-10.
Note: This method is only applicable for reading and creating SSH packets for use within the SSHCustomAuth event.
SSHLogoff Method (SFTP Control)
Logoff from the SSH server.
Syntax
sftpcontrol.SSHLogoff
Remarks
Logoff from the SSH server. If that fails, the connection is terminated by the local host.
SSHLogon Method (SFTP Control)
Logon to the SSHHost using the current SSHUser and SSHPassword .
Syntax
sftpcontrol.SSHLogon SSHHost, SSHPort
Remarks
Logon to the SSH server using the current SSHUser and SSHPassword. This will perform the SSH handshake and authentication.
Example (Logging On)
SSHClient.SSHUser = "username"
SSHClient.SSHPassword = "password"
SSHClient.SSHLogon("sshHost", sshPort)
UpdateFileAttributes Method (SFTP Control)
Instructs the control to send the FileAttributes to the server.
Syntax
sftpcontrol.UpdateFileAttributes

Syntax
sftpcontrol.Upload
Remarks
The local file specified by LocalFile is uploaded to the remote file specified by RemoteFile. RemoteFile is either an absolute path on the server, or a path relative to RemotePath.
If there is no SSH session in place, one is automatically created by the component first.
If you want to append to a server file, please refer to the Append method.
Example (Upload a File)
FTPControl.LocalFile = "C:\\localfile.txt"
FTPControl.RemoteFile = "remotefile.txt"
FTPControl.Upload()
FTPControl.LocalFile = "C:\\localfile2.txt"
FTPControl.RemoteFile = "folder/remotefile2.txt"
FTPControl.Upload()
Connected Event (SFTP Control)
This event is fired immediately after a connection completes (or fails).
Syntax
Sub sftpcontrol_Connected(StatusCode As Integer, Description As String)
Remarks
If the connection is made normally, StatusCode is 0 and Description is "OK".
If the connection fails, StatusCode has the error code returned by the Transmission Control Protocol (TCP)/IP stack. Description contains a description of this code. The value of StatusCode is equal to the value of the error. The corresponding Visual Basic error code can be obtained by adding 15001 to this value.
Please refer to the Error Codes section for more information.
ConnectionStatus Event (SFTP Control)
This event is fired to indicate changes in the connection state.
Syntax
Sub sftpcontrol_ConnectionStatus(ConnectionEvent As String, StatusCode As Integer, Description As String)
Remarks
The ConnectionStatus event is fired when the connection state changes: for example, completion of a firewall or proxy connection or completion of a security handshake.
The ConnectionEvent parameter indicates the type of connection event. Values may include the following:
Firewall connection complete. | |
Secure Sockets Layer (SSL) or S/Shell handshake complete (where applicable). | |
Remote host connection complete. | |
Remote host disconnected. | |
SSL or S/Shell connection broken. | |
Firewall host disconnected. |
DirList Event (SFTP Control)
Fired when a directory entry is received.
Syntax
Sub sftpcontrol_DirList(DirEntry As String, FileName As String, IsDir As Boolean, FileSize As Long64, FileTime As String, IsSymlink As Boolean)
Remarks
The DirList events are fired when a directory listing is received as a response to a ListDirectory.
The StartTransfer and EndTransfer events mark the beginning and end of the event stream.
The DirEntry parameter contains the filename when ListDirectory is called.
The control tries to fill out the FileName, IsDir, FileSize, and FileTime parameters when calling the ListDirectory method.
The format of the FileTime parameter returned by the control can be controlled through the FileTimeFormat configuration setting. If no format is specified, the control will format the date dependent on the year. If the filetime is in the same year, it will be formatted as "MMM dd HH:mm", otherwise it will be formatted as "MMM dd yyyy".
IsSymlink indicates whether the entry is a symbolic link. When the entry is a symbolic link the value of IsDir will always be False since this information is not returned in the directory listing. To inspect a symlink to determine if it is a link to a file or folder set RemoteFile and query the FileIsDir property.
Disconnected Event (SFTP Control)
This event is fired when a connection is closed.
Syntax
Sub sftpcontrol_Disconnected(StatusCode As Integer, Description As String)
Remarks
If the connection is broken normally, StatusCode is 0 and Description is "OK".
If the connection is broken for any other reason, StatusCode has the error code returned by the Transmission Control Protocol (TCP/IP) subsystem. Description contains a description of this code. The value of StatusCode is equal to the value of the TCP/IP error. The corresponding Visual Basic error code can be obtained by adding 15001 to this value.
Please refer to the Error Codes section for more information.
EndTransfer Event (SFTP Control)
Fired when a file completes downloading/uploading.
Syntax
Sub sftpcontrol_EndTransfer(Direction As Integer, LocalFile As String, RemoteFile As String)
Remarks
The EndTransfer event fires when either an upload or a download operation completes. This is when the file finishes transferring and/or a directory listing is finished.
The Direction parameter shows whether the client (0) or the server (1) is sending the data.
LocalFile identifies the local file. RemoteFile is the remote file.
Error Event (SFTP Control)
Information about errors during data delivery.
Syntax
Sub sftpcontrol_Error(ErrorCode As Integer, Description As String, LocalFile As String, RemoteFile As String)
Remarks
The Error event is fired in case of exceptional conditions during message processing. Normally the control fails with an error.
ErrorCode contains an error code and Description contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.
LocalFile identifies the local file. RemoteFile is the remote file.
Log Event (SFTP Control)
Fires once for each log message.
Syntax
Sub sftpcontrol_Log(LogLevel As Integer, Message As String, LogType As String)
Remarks
This event fires once for each log messages generated by the control. The verbosity is controlled by the LogLevel setting.
LogLevel indicates the detail level of the message. Possible values are:
0 (None) | No messages are logged. |
1 (Info - Default) | Informational events such as SSH handshake messages are logged. |
2 (Verbose) | Detailed data such as individual packet information is logged. |
3 (Debug) | Debug data including all relevant sent and received bytes are logged. |
Message is the log message.
LogType is reserved for future use.
SSHCustomAuth Event (SFTP Control)
Fired when the control is doing custom authentication.
Syntax
Sub sftpcontrol_SSHCustomAuth(Packet As String)
Remarks
SSHCustomAuth is fired during the user authentication stage of the SSH logon process if SSHAuthMode is set to amCustom. Packet contains the raw last SSH packet sent by the server, in HEX-encoded format.
The client should create a new raw SSH packet to send to the server and set Packet to the HEX-encoded representation of the packet to send.
In all cases, Packet will start with the message type field.
To read the incoming packet call DecodePacket and then use the GetSSHParam and GetSSHParamBytes methods. To create a packet use the SetSSHParam method and then call EncodePacket to obtain a HEX-encoded value and assign this to the Packet parameter.
SSHKeyboardInteractive Event (SFTP Control)
Fired when the control receives a request for user input from the server.
Syntax
Sub sftpcontrol_SSHKeyboardInteractive(Name As String, Instructions As String, Prompt As String, Response As String, EchoResponse As Boolean)
Remarks
SSHKeyboardInteractive is fired during the user authentication stage of the SSH logon process. During authentication, the control will request a list of available authentication methods for the SSHUser. For example, if the SSHHost responds with "keyboard-interactive", the control will fire this event to allow the client application to set the password.
During authentication, the SSH server may respond with a request for the user's authentication information. Name is a server-provided value associated with the authentication method such as "CRYPTOCard Authentication". Instructions will contain specific instructions, also supplied by the server, for how the user should respond.
Along with these values, the server will also send at least one input Prompt to be displayed to and filled out by the user. Response should be set to the user's input, and will be sent back in the user authentication information response. EchoResponse is a server recommendation for whether or not the user's response should be echoed back during input.
Note: the server may send several prompts in a single packet. The control will fire the SSHKeyboardInteractive event once for each prompt.
SSHServerAuthentication Event (SFTP Control)
Fired after the server presents its public key to the client.
Syntax
Sub sftpcontrol_SSHServerAuthentication(HostKey As String, Fingerprint As String, KeyAlgorithm As String, CertSubject As String, CertIssuer As String, Status As String, Accept As Boolean)
Remarks
This event is where the client can decide whether to continue with the connection process or not. If the public key is known to be a valid key for the SSH server, Accept should be set to True within the event. Otherwise, the server will not be authenticated and the connection will be broken.
Accept will be True only if either HostKey or Fingerprint is identical to the value of SSHAcceptServerHostKey.
Accept may be set to True manually to accept the server host key.
Note that SSH's security inherently relies on client verification of the host key. Ignoring the host key and always setting Accept to true is strongly discouraged, and could cause potentially serious security vulnerabilities in your application. It is recommended that clients maintain a list of known keys for each server and check HostKey against this list each time a connection is attempted.
Host Key contains the full binary text of the key, in the same format used internally by SSH.
Fingerprint holds the SHA-256 hash of HostKey in the hex-encoded form: 0a:1b:2c:3d. To configure the hash algorithm used to calculate this value see SSHFingerprintHashAlgorithm.
KeyAlgorithm identifies the host key algorithm. Supported values are:
- ssh-rsa
- ssh-dss
- rsa-sha2-256
- rsa-sha2-512
- x509v3-sign-rsa
- x509v3-sign-dss
- ecdsa-sha2-nistp256
- ecdsa-sha2-nistp384
- ecdsa-sha2-nistp521
CertSubject is the subject of the certificate. This is only applicable when KeyAlgorithm is "x509v3-sign-rsa" or "x509v3-sign-dss".
CertIssuer is the issuer of the certificate. This is only applicable when KeyAlgorithm is "x509v3-sign-rsa" or "x509v3-sign-dss".
Status is reserved for future use.
SSHStatus Event (SFTP Control)
Shows the progress of the secure connection.
Syntax
Sub sftpcontrol_SSHStatus(Message As String)
Remarks
The event is fired for informational and logging purposes only. Used to track the progress of the connection.
StartTransfer Event (SFTP Control)
Fired when a file starts downloading/uploading.
Syntax
Sub sftpcontrol_StartTransfer(Direction As Integer, LocalFile As String, RemoteFile As String)
Remarks
The StartTransfer event fires when a Data Interface connection is created. This is when the file starts transferring and/or a directory listing is started.
The Direction parameter shows whether the client (0) or the server (1) is sending the data.
LocalFile identifies the local file. RemoteFile is the remote file.
Transfer Event (SFTP Control)
Fired during file download/upload.
Syntax
Sub sftpcontrol_Transfer(Direction As Integer, LocalFile As String, RemoteFile As String, BytesTransferred As Long64, PercentDone As Integer, Text As String, Cancel As Boolean)
Remarks
One or more Transfer events are fired during file transfer. The BytesTransferred parameter shows the number of bytes transferred since the beginning of the transfer.
Text contains the portion of the file data being delivered.
The Direction parameter shows whether the client (0) or the server (1) is sending the data.
LocalFile identifies the local file. RemoteFile is the remote file.
The PercentDone parameter shows the progress of the transfer in the corresponding direction. If PercentDone can not be calculated the value will be -1.
To cancel the current transfer set Cancel to true.
Config Settings (SFTP Control)
The control 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 control, access to these internal properties is provided through the Config method.SFTP Config Settings
The default value is False.
The server must support the check-file extension.
The control supports the following hash algorithms (in order of preference): sha256,sha224,sha384,sha512,sha1,md5. The server may choose to use any value from this list. No action is needed to configure the algorithm, the control will automatically use the same algorithm that the server users.
If the extension is unsupported or a mismatch in hashes is detected the control fails with an error. If the hashes match the value "True" is returned.
try {
String flag = sftp.Config("CheckFileHash");
// flag will be equal to "True"
}
catch (Exception e) {
// mismatch
}
Set RemoteFile to the path of the source file. Optionally set StartByte to indicate from where in the source file to start reading.
Then set CopyRemoteData to a semi-colon (;) delimited listed of Name=Value pairs. In this list DestFile must be set to the path of the
destination file. Length may be set to the number of bytes to read. WriteOffset may be set to the location in the destionation file
from where to start writing.
sftp.RemoteFile = "/my/source/file.txt";
sftp.Overwrite = true;
sftp.StartByte = 6;
sftp.Config("CopyRemoteData=DestFile=/my/destination/file.txt;Length=5;WriteOffset=14");
Set RemoteFile to the path of the source file, then set CopyRemoteFile to the path of the destination file. Overwrite controls
whether an existing file will be overwritten.
sftp.Overwrite = true;
sftp.RemoteFile = "/my/source/file.txt";
sftp.Config("CopyRemoteFile=" + "/my/destination/file.txt");
Note: The server must understand either the "statvfs@openssh.com" or "space-available" extension in order for this operation to succeed.
If it is desired to retrieve the attributes of the symbolic link itself, set GetSymlinkAttrs to True before querying FileAttributes.
When uploading or downloading this value will be compared to ServerEOL. If ServerEOL and LocalEOL are different, the line endings in the file being transferred will be converted to the line endings used by the destination. Line endings will be converted to the value in LocalEOL when downloading. Line endings will be converted to the value in ServerEOL when uploading. If ServerEOL and LocalEOL are the same, no conversion takes place.
The value supplied to this setting must be quoted. For instance:
component.Config("LocalEOL=\"" + myEOLSequence + "\"");
Where myEOLSequence is a Cr, Lf, or CrLf character sequence.
Conversion will only happen when TransferMode is set to 1 (ASCII) and ServerEOL and LocalEOL are different.
Most servers that use smaller values will use a maximum SSH packet size of 16KB (16384). In order to most efficiently communicate with such servers, MaxFileData size should be set to 14745.
Note: Values larger than 64K (65536) may not be respected by some servers (such as OpenSSH) and will result in unexpected behavior. If specifying a value, it is recommended to set a value less than or equal to 65536.
The default value is 32768.
string resolvedPath = component.Config("ReadLink=/home/test/mysymlink.txt");
SSH_FXP_REALPATH_NO_CHECK (1) | Server should not check if the path exists. |
SSH_FXP_REALPATH_STAT_IF (2) | Server should return the file/directory attributes if the path exists and is accessible, but should not fail otherwise. |
SSH_FXP_REALPATH_STAT_ALWAYS (3) | Server should return the file/directory attributes if the path exists and is accessible, otherwise fail with an error. |
When uploading or downloading this value will be compared to LocalEOL. If ServerEOL and LocalEOL are different, the line endings in the file being transferred will be converted to the line endings used by the destination. Line endings will be converted to the value in LocalEOL when downloading. Line endings will be converted to the value in ServerEOL when uploading. If ServerEOL and LocalEOL are the same, no conversion takes place.
The value supplied to this setting must be quoted. For instance:
component.Config("ServerEOL=\"" + myEOLSequence + "\"");
Where myEOLSequence is a Cr, Lf, or CrLf character sequence.
Conversion will only happen when TransferMode is set to 1 (ASCII) and ServerEOL and LocalEOL are different.
When this value is set to 1 (ASCII) the control will use the values specified in LocalEOL and ServerEOL to convert line endings as appropriate.
Note: When this value is set to 1 (ASCII) and ProtocolVersion is set to 4 or higher the control will automatically determine the value for ServerEOL if the server supports the "newline" protocol extension.
This setting can be used in conjunction with the StartByte property in order to download a specific range of data from the current RemoteFile.
Set this to to not send the packet. This will cause PreserveFileTime to not work and prevent PercentDone in Transfer from being calculated.
The default is .
SSHClient Config Settings
If MaxChannelDataLength > 0 and ChannelDataEOL is a non-empty string the control will internally buffer data waiting to fire SSHChannelData until either MaxChannelDataLength is reached or ChannelDataEOL is found, whichever comes first. Query ChannelDataEOLFound to know which condition was met. The buffer is reset any time SSHChannelData fires.
ChannelDataEOL and MaxChannelDataLength MUST be set together or unexpected behavior could occur.
This config is only valid when queried inside SSHChannelData, MaxChannelDataLength > 0, and ChannelDataEOL is non-empty.
Most SSH servers expect the SSH version string to have the expected format "SSH-protocol version-software version". See above for an example.
Value | Description |
0 (Disabled - default) | No communication with Pageant is attempted. |
1 (Enabled) | Pageant authentication is used if available. If Pageant is not running, or does not contain the expected key no error is thrown. |
2 (Required) | Only Pageant authentication is used. If Pageant is not running, or does not contain the expected key an error is thrown. |
Example enabling Pageant:
component.Config("EnablePageantAuth=1");
component.SSHUser = "sshuser";
component.SSHLogon("localhost", 22);
Note: This functionality is only available on Windows.
Example (for setting the threshold to 500 MB):
SSHComponent.Config("KeyRenegotiationThreshold=524288000")
0 (None) | No messages are logged. |
1 (Info - Default) | Informational events such as SSH handshake messages are logged. |
2 (Verbose) | Detailed data such as individual packet information is logged. |
3 (Debug) | Debug data including all relevant sent and received bytes are logged. |
If MaxChannelDataLength > 0 and ChannelDataEOL is a non-empty string the control will internally buffer data waiting to fire SSHChannelData until either MaxChannelDataLength is reached or ChannelDataEOL is found, whichever comes first. Query ChannelDataEOLFound to know which condition was met. The buffer is reset any time SSHChannelData fires.
ChannelDataEOL and MaxChannelDataLength MUST be set together or unexpected behavior could occur.
component.Config("NegotiatedStrictKex")
This provides an easy way to automatically reply to prompts with the password if one is presented by the server. The password will be auto-filled in the Response parameter of the SSHKeyboardInteractive event in the case of a match.
The following special characters are supported for pattern matching:
? | Any single character. |
* | Any characters or no characters (e.g., C*t matches Cat, Cot, Coast, Ct). |
[,-] | A range of characters (e.g., [a-z], [a], [0-9], [0-9,a-d,f,r-z]). |
\ | The slash is ignored and exact matching is performed on the next character. |
If these characters need to be used as a literal in a pattern, then they must be escaped by surrounding them with brackets []. Note: "]" and "-" do not need to be escaped. See below for the escape sequences:
Character | Escape Sequence |
? | [?] |
* | [*] |
[ | [[] |
\ | [\] |
For example, to match the value [Something].txt, specify the pattern [[]Something].txt.
The default value is 0, meaning this setting is not used.
component.Config("SignedSSHCert=ssh-rsa-cert-v01@openssh.com AAAAB3NzaC1yc2EAAAADAQABAAAB...");
The algorithm such as ssh-rsa-cert-v01@openssh.com in the above string is used as part of the authentication process. To use a different algorithm simply change this value. For instance all of the following are acceptable with the same signed public key:
- ssh-rsa-cert-v01@openssh.com AAAAB3NzaC1yc2EAAAADAQABAAAB...
- rsa-sha2-256-cert-v01@openssh.com AAAAB3NzaC1yc2EAAAADAQABAAAB...
- rsa-sha2-512-cert-v01@openssh.com AAAAB3NzaC1yc2EAAAADAQABAAAB...
component.Config("SSHAcceptServerCAKey=ssh-rsa AAAAB3NzaC1yc2EAAAADAQAB...");
SSHClient.Config("SSHAcceptServerHostKeyFingerprint=0a:1b:2c:3d");
If the server's fingerprint matches one of the values supplied, the control will accept the host key.
- MD5
- SHA1
- SHA256 (default)
The default value is 0 meaning no keep alives will be sent.
Note: The SSHREVERSETUNNEL control uses a default value of 30.

The setting should be a comma separated list of algorithms. At runtime the control will evaluate the specified algorithms and if the algorithm is applicable to the certificate specified in SSHCert it will be used. If the algorithm is not applicable the control will evaluate the next algorithm. Possible values are:
- ssh-rsa
- rsa-sha2-256
- rsa-sha2-512
- ssh-dss
- ecdsa-sha2-nistp256
- ecdsa-sha2-nistp384
- ecdsa-sha2-nistp521
- ssh-ed25519
- x509v3-sign-rsa
- x509v3-sign-dss
The default value in Windows is ssh-rsa,rsa-sha2-256,rsa-sha2-512,ssh-dss,ecdsa-sha2-nistp256,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521,ssh-ed25519.
rsa-sha2-256 and rsa-sha2-512 notes
The control will query the server for supported algorithms when connecting. If the server indicates support for rsa-sha2-256 or rsa-sha2-512 and the algorithm is present in the list defined by this setting (as in the default value), that algorithm will be used instead of ssh-rsa even when ssh-rsa appears first in the list.
For the rsa-sha2-256 and rsa-sha2-512 algorithms to be automatically preferred the server must support the ext-info-c mechanism. In practice, older servers do not support this and in that case ssh-rsa will be used since it appears first in the list. Newer servers do support this mechanism and in that case rsa-sha2-256 or rsa-sha2-512 will be used even though it appears after ssh-rsa.
This behavior has been carefully designed to provide maximum compatibility while automatically using more secure algorithms when connecting to servers which support them.
*SSH-1.99-*,*SSH-2.0-*,*SSH-2.99-*
Since both client and server must implement strict key exchange to effectively mitigate the Terrapin attack, the control provides options to further control the behavior in different scenarios. Possible values for this setting are:
0 | Disabled. Strict key exchange is not supported in the control. |
1 (default) | Enabled, but not enforced. This setting enables strict key exchange, but if the remote host does not support strict key exchange the connection is still allowed to continue. |
2 | Enabled, but reject affected algorithms if the remote host does not support strict key exchange. If the remote host supports strict key exchange all algorithms may be used. If the remote host does not support strict key exchange the connection will only continue if the selected encryption and MAC algorithms are not affected by the Terrapin attack. |
3 | Required. If the remote host does not support strict key exchange the connection will fail. |
When True (default) the control will wait for a response to the channel close message until the responses have been received, the server closes the connection, or Timeout seconds is reached.
When False the control will still send the channel close messages but will not wait for a response and will proceed to close the connection.
When set to True the control will initiate the disconnection sequence by sending SSH_MSG_DISCONNECT but will not close the connection, and instead will wait for the server to close the connection. Setting this to True may be beneficial in circumstances where many connections are being established, to avoid port exhaustion when sockets are in a TIME_WAIT state. Allowing the server to close the connection avoids the TIME_WAIT state of socket on the client machine.
When set to False (default) the client will close the connection. It is recommended to use this value unless there is a specific need to change it.

In the case that Linger is True (default), two scenarios determine how long the connection will linger. In the first, if LingerTime is 0 (default), the system will attempt to send pending data for a connection until the default IP timeout expires.
In the second scenario, if LingerTime is a positive value, the system will attempt to send pending data until the specified LingerTime is reached. If this attempt fails, then the system will reset the connection.
The default behavior (which is also the default mode for stream sockets) might result in a long delay in closing the connection. Although the control returns control immediately, the system could hold system resources until all pending data are sent (even after your application closes).
Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (e.g., by a client acknowledgment), setting this property to False might be the appropriate course of action.
In multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the control initiate connections (or accept in the case of server controls) only through that interface.
If the control is connected, the LocalHost setting shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multi-homed hosts (machines with more than one IP interface).
Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by LocalPort after the connection is established.
LocalPort cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error.
This; setting is useful when trying to connect to services that require a trusted port in the client side. An example is the remote shell (rsh) service in UNIX systems.
If an EOL string is found in the input stream before MaxLineLength bytes are received, the DataIn event is fired with the EOL parameter set to True, and the buffer is reset.
If no EOL is found, and MaxLineLength bytes are accumulated in the buffer, the DataIn event is fired with the EOL parameter set to False, and the buffer is reset.
The minimum value for MaxLineLength is 256 bytes. The default value is 2048 bytes.
