SFTPClient Module

Properties Methods Events Config Settings Errors

The SFTPClient module provides client-side functionality for SFTP (Secure File Transfer Protocol).

Syntax

SecureBlackbox.SFTPClient

Remarks

SFTP is a file transfer subsystem that runs on top of secure shell (SSH) connection. This means that SFTP uses the whole strength of security provided by the SSH protocol, at the same time providing strong file transfer capabilities.

Please do keep in mind that there exist two protocols that offer similar secure file transfer features. SFTP works on top of SSH and normally uses port 22. FTPS works on top of TLS (or SSL) and normally uses ports 21 and 990. The protocols are very different, so please make sure you are after the right component. This component works with SFTP. Use the FTPClient component to connect to FTPS servers.

Below are the typical steps that let you integrate SFTPClient to your project:

Set up your Username and Password. SSH uses mandatory client-side authentication, so in most cases you need to provide your username, your password, or, sometimes, your private key. Use Key property to provide your key, if needed.
Be ready to handle server authentication, which is also mandatory in SSH. SSH operates a concept of a trusted keys file, where keys of known servers are stored. You can assign a path to your own trusted keys file to the TrustedKeysFile property. When a client receives a server key, it reports it to your code via its KnownKeyReceived or UnknownKeyReceived event, depending on whether the key was found in the trusted list. If you leave TrustedKeysFile empty, SFTPClient will only be able to fire the UnknownKeyReceived event, since there will be no known keys to report.
If needed, customize Proxy parameters and SSHSettings.
Consider interacting more with SFTPClient by subscribing to AuthAttempt, AuthFailed, and AuthSucceeded events to be notified about the client authentication progress.
When you are ready to connect, call Connect, passing the details of the server as parameters. During the initial handshake, the following events will fire: UnknownKeyReceived (or KnownKeyReceived), and then one or more AuthAttempt, AuthFailed and AuthSucceeded.
Upon completion of the Connect method, the component is ready for file operations. Use DownloadFile, UploadFile, ListDir, DeleteFile and other file transfer methods to work with the server file system.
When you are done with your work, call Disconnect to close the connection.

Some SFTP servers, primarily older ones, may expose various transfer issues. If you come across a weird issue that you believe should not be happening (such as repeated connection closures in the middle of the transfer), please try adjusting the following properties:

AutoAdjustTransferBlock to false,
PipelineLength to 1,
UploadBlockSize to 16384,
DownloadBlockSize to 16384.

These adjustments will put SFTPClient in very conservative transfer setup. While this setup may be quite sluggish with modern servers, it should make SFTPClient interoperable with most older servers.

Remarks

RemotePath contains a file mask or regular expression by which the files are selected for download.

LocalDir specifies the local folder where the files should be saved. The Recursive parameter tells the component whether it should navigate source directories recursively when downloading files. If set to false, only the files residing in the actual RemotePath, but not its subdirectories, will be downloaded.

The ErrorHandling parameter specifies the error handling tactics.


ehStopOnFailure	`0`	Stop on the first failure and throw an exception
ehIgnoreErrors	`1`	Ignore individual processing errors, just proceed to the next item on the list

Remarks

Use this property to upload a batch of files to the server.

LocalPath specifies a wildcard or regular expression by which the local files are picked for uploading. RemoteDir specifies the location on the server where these files should be saved. The Recursive parameter tells the component whether it should navigate source directories recursively when uploading files. If set to false, only the files residing in the actual LocalPath, but not its subdirectories, will be uploaded.

The ErrorHandling parameter specifies one of the pre-defined error handling tactics:


ehStopOnFailure	`0`	Stop on the first failure and throw an exception
ehIgnoreErrors	`1`	Ignore individual processing errors, just proceed to the next item on the list
ehTryAllItems	`2`	Try to process all the items by ignoring any mid-way errors, but throw an exception at the end of the processing if any of the items failed to process

AuthAttempt Event (SFTPClient Module)

Fires when an authentication attempt is performed.

Syntax

Swift
Objective-C

func onAuthAttempt(authType: Int32)

- (void)onAuthAttempt:(int)authType;

Remarks

This event signals the start of an authentication attempt. The AuthType parameter specifies the authentication type. This event may be fired more than once if the client tries different authentication methods one after another.

Supported authentication types:


atRhosts	`0x01`	RHOSTS file authentication. Rarely used today.
atPublicKey	`0x02`	Public key (sometimes called private key) authentication
atPassword	`0x04`	Password-based authentication
atHostbased	`0x08`	Hostbased authentication
atKeyboard	`0x10`	Keyboard-interactive authentication. This is often used in place of generic password authentication.
atGssWithMic	`0x20`	GSS authentication
atGssKeyex	`0x40`	GSS authentication with key exchange
atPublicKeyAgent	`0x80`	Public key agent authentication

AuthFailed Event (SFTPClient Module)

Fires if an authentication attempt fails.

Syntax

Swift
Objective-C

func onAuthFailed(authType: Int32)

- (void)onAuthFailed:(int)authType;

Remarks

This event fires if an authentication attempt fails (for example, if a bad password had been provided). AuthType parameter indicates the authentication type.

AuthFailed may be fired more than once, depending on the configured authentication parameters and the value assigned to the AuthAttempts property.

This event does not necessarily lead to connection abortion, as the client may still have a chance of authenticating with a different method.

Supported authentication types:


atRhosts	`0x01`	RHOSTS file authentication. Rarely used today.
atPublicKey	`0x02`	Public key (sometimes called private key) authentication
atPassword	`0x04`	Password-based authentication
atHostbased	`0x08`	Hostbased authentication

Syntax

Swift
Objective-C

func onBanner(text: Data, language: Data)

- (void)onBanner:(NSData*)text :(NSData*)language;

Remarks

The class fires this event when it receives a welcome message from the server. Use the Text parameter to access the encoded message.

Disconnect Event (SFTPClient Module)

Reports SFTP connection closure.

Syntax

Swift
Objective-C

func onDisconnect(closeReason: Int32)

- (void)onDisconnect:(int)closeReason;

ExternalSign Event (SFTPClient Module)

Handles remote or external signing initiated by the SignExternal method or other source.

Syntax

Swift
Objective-C

func onExternalSign(operationId: String, hashAlgorithm: String, pars: String, data: String, signedData: inout String)

- (void)onExternalSign:(NSString*)operationId :(NSString*)hashAlgorithm :(NSString*)pars :(NSString*)data :(NSString**)signedData;

Remarks

Assign a handler to this event if you need to delegate a low-level signing operation to an external, remote, or custom signing engine. Depending on the settings, the handler will receive a hashed or unhashed value to be signed.

The event handler must pass the value of Data to the signer, obtain the signature, and pass it back to the class via the SignedData parameter.

OperationId provides a comment about the operation and its origin. It depends on the exact class being used, and may be empty. HashAlgorithm specifies the hash algorithm being used for the operation, and Pars contains algorithm-dependent parameters.

The class uses base16 (hex) encoding for the Data, SignedData, and Pars parameters. If your signing engine uses a different input and output encoding, you may need to decode and/or encode the data before and/or after the signing.

A sample MD5 hash encoded in base16: a0dee2a0382afbb09120ffa7ccd8a152 - lower case base16 A0DEE2A0382AFBB09120FFA7CCD8A152 - upper case base16

A sample event handler that uses the .NET RSACryptoServiceProvider class may look like the following: signer.OnExternalSign += (s, e) => { var cert = new X509Certificate2("cert.pfx", "", X509KeyStorageFlags.Exportable); var key = (RSACryptoServiceProvider)cert.PrivateKey; var dataToSign = e.Data.FromBase16String(); var signedData = key.SignHash(dataToSign, "2.16.840.1.101.3.4.2.1"); e.SignedData = signedData.ToBase16String(); };

Syntax

Swift
Objective-C

func onNotification(eventID: String, eventParam: String)

- (void)onNotification:(NSString*)eventID :(NSString*)eventParam;

Remarks

The class fires this event to let the application know about some event, occurrence, or milestone in the class. For example, it may fire to report completion of the document processing. The list of events being reported is not fixed, and may be flexibly extended over time.

The unique identifier of the event is provided in the EventID parameter. EventParam contains any parameters accompanying the occurrence. Depending on the type of the class, the exact action it is performing, or the document being processed, one or both may be omitted.

PasswordChangeRequest Event (SFTPClient Module)

Signals that the server requests a password change.

Syntax

Swift
Objective-C

func onPasswordChangeRequest(prompt: String, newPassword: inout String, cancel: inout Bool)

- (void)onPasswordChangeRequest:(NSString*)prompt :(NSString**)newPassword :(int*)cancel;

Syntax

Swift
Objective-C

func onUnknownKeyReceived(algorithm: String, bits: Int32, fingerprintSHA256: String, action: inout Int32)

- (void)onUnknownKeyReceived:(NSString*)algorithm :(int)bits :(NSString*)fingerprintSHA256 :(int*)action;

Remarks

The class fires this event to tell the application that the server has introduced itself with a key not present in TrustedKeysFile.

The details of the key are provided: Algorithm and Bits specify the key algorithm and the number of bits. FingerprintSHA256 contains the key's fingerprint.

In this event handler, you need to make a decision whether to proceed with the connection. Use Action to tell the class what it should do with the key:


catAcceptOnce	`1`	Accept the key for the current session only.
catAcceptPermanently	`2`	Accept the key for the current session and store the key to the trusted keys list.
catReject	`3`	Reject the key and close the connection.

Note that accepting an unknown and unchecked key may be risky.

ExternalCrypto Type

Specifies the parameters of external cryptographic calls.

Remarks

External cryptocalls are used in a Distributed Cryptography (DC) subsystem, which allows the delegation of security operations to the remote agent. For instance, it can be used to compute the signature value on the server, while retaining the client's private key locally.

The following fields are available:

AsyncDocumentID

CustomParams

Data

ExternalHashCalculation

Fields

asyncDocumentID
String
Default Value: ""

Specifies an optional document ID for SignAsyncBegin() and SignAsyncEnd() calls.

Use this property when working with multi-signature DCAuth requests and responses to uniquely identify documents signed within a larger batch. On the completion stage, this value helps the signing component identify the correct signature in the returned batch of responses.

If using batched requests, make sure to set this property to the same value on both the pre-signing (SignAsyncBegin) and completion (SignAsyncEnd) stages.

customParams
String
Default Value: ""

Custom parameters to be passed to the signing service (uninterpreted).

data
String
Default Value: ""

Additional data to be included in the async state and mirrored back by the requestor.

externalHashCalculation
Bool
Default Value: False

Specifies whether the message hash is to be calculated at the external endpoint. Please note that this mode is not supported by the DCAuth class.

If set to true, the class will pass a few kilobytes of to-be-signed data from the document to the OnExternalSign event. This only applies when SignExternal() is called.

hashAlgorithm
String
Default Value: "SHA256"

Specifies the request's signature hash algorithm.

keyID
String
Default Value: ""

The ID of the pre-shared key used for DC request authentication.

Asynchronous DCAuth-driven communication requires that parties authenticate each other with a secret pre-shared cryptographic key. This provides an extra protection layer for the protocol and diminishes the risk of the private key becoming abused by foreign parties. Use this property to provide the pre-shared key identifier, and use to pass the key itself.

The same KeyID/KeySecret pair should be used on the DCAuth side for the signing requests to be accepted.

Note: The KeyID/KeySecret scheme is very similar to the AuthKey scheme used in various Cloud service providers to authenticate users.

Example: signer.ExternalCrypto.KeyID = "MainSigningKey"; signer.ExternalCrypto.KeySecret = "abcdef0123456789";

keySecret
String
Default Value: ""

The pre-shared key used for DC request authentication. This key must be set and match the key used by the DCAuth counterpart for the scheme to work.

Remarks

The class represents the details of a file entry returned by the FTP server.

The following fields are available:

Fields

accessTime
String
Default Value: ""

Contains the last access time for this file, in UTC.

creationTime
String
Default Value: ""

Contains this file's creation time, in UTC.

entryFormat
FTPFileFormats
Default Value: 0

The file listing format:


cfefUnknown	`0`
cfefUnix	`1`
cfefWindows	`2`
cfefMLSD	`3`

fileType
FTPFileTypes
Default Value: 0

The type of the entry:

handle
Int64
Default Value: 0

Allows to get or set a 'handle', a unique identifier of the underlying property object. Use this property to assign objects of the same type in a quicker manner, without copying them fieldwise.

When you pass a handle of one object to another, the source object is copied to the destination rather than assigned. It is safe to get rid of the original object after such operation. pdfSigner.setSigningCertHandle(certMgr.getCertHandle());

Creates a new object with default settings.

Config Settings (SFTPClient Module)

The class accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

SFTPClient Config Settings

AdjustFileTimes: Whether file times should be adjusted after upload/download.

If this property value is True, file times (creation, access and last modification times) will be adjusted after upload/download operation.

AllAlgorithms: Returns the list of algorithms enabled in the component.

Use this configuration setting to obtain the list of algorithms currently enabled in the component in the kexinit format.

ASCIIMode: Whether ASCII transfer mode is used.

When this property is True, ASCII (text) transfer mode is used, otherwise the transfer is performed in binary mode.

AvailableSpace: Returns details of server disk space availability. This protocol extension must be supported by the server for this request to work.

This config property returns the details of the server disk space. The information is provided in the form of semicolon-separated entries: BytesOnDevice, UnusedBytesOnDevice, BytesAvailableToUser, UnusedBytesAvailableToUser, BytesPerAllocationUnit. You can use this property without parameters, or provide a specific mounting point in brackets: AvailableSpace(./path).

CaseConversion: Whether file names and paths should be case-converted.

Defines whether file names are converted (on the destination system) to: lowercase (1), uppercase (2).

CaseSensitive: Specifies if file paths are case-sensitive.

Set this property to True if all file names, paths and file masks should be case-sensitive.

CloseQuietly: Controls the client's approach to session closure.

The quiet closure entails the client shutting down the connection immediately without expecting graceful notifications from the other side. When closing non-quietly, the client will close the connection gradually, starting from the SSH session before proceeding to shutdown-based socket closure. Both options have their pros and cons; choose carefully the option that you want to use going forward.

CommandTimeout: Specifies the command timeout.

Specifies the command timeout (the maximum time to expect the result from the SSH command), in milliseconds.

CompressionAlgorithms: Returns the list of compression algorithms enabled in the component.

Use this configuration setting to get the list of compression algorithms currently enabled in the component, as a respective kexinit block line.

CopyMode: Defines what to do with each successfully copied file.

You could choose to: simply copy the file, delete each file's origin right after that file has been copied, or delete all original files only after all files have been copied.

DefaultTransferBlock: Specifies the default transfer block size.

This setting provides means to adjust the size of the SFTP transfer block (i.e. the size of the content of the write and read packets). It can be used to influence the transfer speed.

DefOutboundBlockSize: The default outbound block size.

Use this property to configure the outbound data block size.

DisablePacketFragmentation: Enables or disables SSH packet fragmentation.

Use this property to enable or disable SSH packet fragmentation. This is one of the settings that is worth a look if encountering unexplained transfer issues.

EarlyIdString: Enables the proactive approach to SSH handshake.

The rule of thumb in the majority of SSH environments is for the server to initiate the handshake with its identification string (and for the client to respond). By setting this property to true you can tell the client to initiate the handshake by sending out the identification string proactively without waiting for the server to send one in. This setting may help in situations where your SSH or SFTP connection fails unexpectedly due to a timeout or network error.

EncryptionAlgorithms: Returns the list of encryption algorithms enabled in the component.

Use this configuration setting to get the list of symmetric encryption algorithms currently enabled in the component, as a respective kexinit block line.

ErrorOrigin: Specifies whether the error is local or remote.

Use this property to check where the error took place.

ErrorSeverity: Specifies whether the error is fatal.

Use this property to check whether the error is fatal or not.

FileHash: Returns the hash of the specified file. This protocol extension must be supported by the server for this request to work.

Use this property to request the hash of a remote file. Pass the file name in brackets: FileHash(./path/file.ext). You can adjust the hash algorithm using the HashAlgorithm configuration setting.

HashAlgorithm: The hash algorithm to use for the protocol operations.

Specifies the hash algorithm to use for file protocol operations, such as FileHash.

HomeDir: Returns a user's home directory. This protocol extension must be supported by the server for this request to work.

Use this property to request a specific user's home directory on the server. Provide the username in brackets: HomeDir(user2).

IncomingSpeedLimit: Specifies incoming speed limit.

Use this property to limit the maximum number of bytes per second that client may receive. The value of 0 (zero) means "no limitation".

KeepAlivePeriod: The inactivity period after which a keep-alive signal will be sent.

Use this property to specify tunnel inactivity period (in milliseconds) after which a keep-alive signal will be sent. The default value is 0 (no keep-alive signals).

KexAlgorithms: Returns the list of key exchange algorithms enabled in the component.

Use this configuration setting to get the list of key exchange algorithms currently enabled in the component, as a respective kexinit block line.

LocalCharset: Charset used on the client machine.

This property specifies the charset used on the local client computer.

LocalNewLineConvention: A character string for the end of line (EOL) indication on the local machine.

This property contains a character string for the end of line (EOL) indication on the local machine.

Use this configuration setting to get the list of MAC algorithms currently enabled in the component, as a respective kexinit block line.

NewLineConvention: A character string for the end of line (EOL) indication on the server.

This property contains a character string for the end of line (EOL) indication used by the server. Usually its value is one of: 0x0d, 0x0d0x0a, 0x0a0x0d, or 0x0a, but it can differ for some servers.

OutgoingSpeedLimit: Specifies incoming speed limit.

Use this property to limit the maximum number of bytes per second that client may send. The value of 0 (zero) means "no limitation".

PreserveExistingFileTimes: Whether original file times should be restored upon transfer.

If the destination file exists and PreserveExistingFileTimes option is enabled, the class will remember the file's times before transfer, and restore them after the file has been transferred. The default value is False.

PublicKeyAlgorithms: Returns the list of public key algorithms enabled in the component.

Use this configuration setting to get the list of public key algorithms currently enabled in the component, as a respective kexinit block line.

Use this property to request a path to the temporary directory maintained by the server.

TempPath: Path for storing temporary files.

This setting specifies an absolute path to the location on disk where temporary files are stored.

TreatZeroSizeAsUndefined: Whether zero size returned by STAT should be considered as undefined.

This property specifies if the size of zero returned by the STAT command for a particular file should be considered as undefined. It makes sense to set this property to True, because some operating systems (e.g. Unix-based) return zero size for the files of certain type. For instance, most of the files contained in the /proc directory are reported as 0-sized, while actually not being empty.

TryPasswordAuth: Specifies whether the component should attempt the password-based authentication if no password is set.

If the Password property is not set, the component disables the password-based authentication. Set this property to true to make it try the empty password instead.

UseStrictKeyExchange: Specifies how strict key exchange is supported.

This setting controls whether strict key exchange (strict kex) is enabled to mitigate the Terrapin attack. When enabled, the class will indicate support for strict key exchange by automatically including the pseudo-algorithm kex-strict-c-v00@openssh.com for client classes and kex-strict-s-v00@openssh.com for server classes in the list of supported key exchange algorithms.

Since both client and server must implement strict key exchange to effectively mitigate the Terrapin attack, the class 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 class.
`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.

UseTruncateFlagOnUpload: whether to use the 'truncate' flag on file upload.

If this property is True, the existing files are opened truncated on upload, otherwise new files are created. The default value is True.

UseUTF8OnV3: Whether to apply UTF-8 conversion for SFTP protocol versions 3 and lower.

If this property is True, UTF-8 encoding will be applied to file names for SFTP protocol versions 3 and lower.

Use this property to get or set an IP address for the specified domain name in the internal (of the class) or global DNS rules storage depending on the StaticDNS value. The type of the IP address (IPv4 or IPv6) is determined automatically. If both addresses are available, they are devided by the | (pipe) character.

StaticIPAddresses: Gets or sets all the static DNS rules.

Use this property to get static DNS rules from the current rules storage or restore them back between application sessions. If StaticDNS of the class is set to "local", the property returns/restores the rules from/to the internal storage of the class. If StaticDNS of the class is set to "global", the property returns/restores the rules from/to the GLOBAL storage. The rules list is returned and accepted in JSON format.

Tag: Allows to store any custom data.

Use this config property to store any custom data.

TLSSessionGroup: Specifies the group name of TLS sessions to be used for session resumption.

Use this property to limit the search of chached TLS sessions to the specified group. Sessions from other groups will be ignored. By default, all sessions are cached with an empty group name and available to all the classes.
