SFTPClient Class
Properties Methods Events Config Settings Errors
The SFTPClient class provides client-side functionality for SFTP (Secure File Transfer Protocol).
Syntax
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.

QString AbsolutePath(const QString& qsRemotePath);
Remarks
Use this method to ask the SFTP server to convert a relative path to an absolute.
Error Handling (C++)
This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.
ChangeDir Method (SFTPClient Class)
Changes current working directory on the server.
Syntax
ANSI (Cross Platform) int ChangeDir(const char* lpszRemoteDir); Unicode (Windows) INT ChangeDir(LPCWSTR lpszRemoteDir);
int secureblackbox_sftpclient_changedir(void* lpObj, const char* lpszRemoteDir);
int ChangeDir(const QString& qsRemoteDir);
Remarks
Changes current working directory on the server to RemoteDir.
Error Handling (C++)
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
Config Method (SFTPClient Class)
Sets or retrieves a configuration setting.
Syntax
ANSI (Cross Platform) char* Config(const char* lpszConfigurationString); Unicode (Windows) LPWSTR Config(LPCWSTR lpszConfigurationString);
char* secureblackbox_sftpclient_config(void* lpObj, const char* lpszConfigurationString);
QString Config(const QString& qsConfigurationString);
Remarks
Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.
These 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.
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.
Error Handling (C++)
This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.
Connect Method (SFTPClient Class)
Connects to an SFTP server.
Syntax
ANSI (Cross Platform) int Connect(const char* lpszAddress, int iPort); Unicode (Windows) INT Connect(LPCWSTR lpszAddress, INT iPort);
int secureblackbox_sftpclient_connect(void* lpObj, const char* lpszAddress, int iPort);
int Connect(const QString& qsAddress, int iPort);
Remarks
Use this method to connect to the SFTP server identified via its Address and Port.
Error Handling (C++)
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
CreateLink Method (SFTPClient Class)
Creates a symbolic or hard link to a remote file.
Syntax
ANSI (Cross Platform) int CreateLink(const char* lpszLinkPath, const char* lpszTargetPath, int bHardLink); Unicode (Windows) INT CreateLink(LPCWSTR lpszLinkPath, LPCWSTR lpszTargetPath, BOOL bHardLink);
int secureblackbox_sftpclient_createlink(void* lpObj, const char* lpszLinkPath, const char* lpszTargetPath, int bHardLink);
int CreateLink(const QString& qsLinkPath, const QString& qsTargetPath, bool bHardLink);
Remarks
Use this method to create a symbolic or hard link on the server. Provide the name of the new link object via the LinkPath parameter, and the destinating file or directory path via the TargetPath parameter. HardLink specifies whether the new link should be hard (true) or symbolic (false).
Error Handling (C++)
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
DeleteDir Method (SFTPClient Class)
Removes directory from the SFTP server.
Syntax
ANSI (Cross Platform) int DeleteDir(const char* lpszRemoteDir); Unicode (Windows) INT DeleteDir(LPCWSTR lpszRemoteDir);
int secureblackbox_sftpclient_deletedir(void* lpObj, const char* lpszRemoteDir);
int DeleteDir(const QString& qsRemoteDir);
Remarks
Use RemoteDir to provide a path to the directory to be deleted.
Error Handling (C++)
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
DeleteFile Method (SFTPClient Class)

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();
};

ExternalCrypto Type
Specifies the parameters of external cryptographic calls.
Syntax
SecureBlackboxExternalCrypto (declared in secureblackbox.h)
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.
Fields
AsyncDocumentID
char*
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
char*
Default Value: ""
Custom parameters to be passed to the signing service (uninterpreted).
Data
char*
Default Value: ""
Additional data to be included in the async state and mirrored back by the requestor.
ExternalHashCalculation
int
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
char*
Default Value: "SHA256"
Specifies the request's signature hash algorithm.

KeyID
char*
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 KeySecret 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
char*
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.
Read more about configuring authentication in the KeyID topic.
Method
int
Default Value: 0
Specifies the asynchronous signing method. This is typically defined by the DC server capabilities and setup.
Available options:
asmdPKCS1 | 0 |
asmdPKCS7 | 1 |
Mode
int
Default Value: 0
Specifies the external cryptography mode.
Available options:
ecmDefault | The default value (0) |
ecmDisabled | Do not use DC or external signing (1) |
ecmGeneric | Generic external signing with the OnExternalSign event (2) |
ecmDCAuth | DCAuth signing (3) |
ecmDCAuthJSON | DCAuth signing in JSON format (4) |
PublicKeyAlgorithm
char*
Default Value: ""
Provide the public key algorithm here if the certificate is not available on the pre-signing stage.

SecureBlackboxStream Type
Syntax
SecureBlackboxStream (declared in secureblackbox.h)
Remarks
The SFTPClient class includes one or more API members that take a stream object as a parameter. To use such API members, create a concrete class that implements the SecureBlackboxStream interface and pass the SFTPClient class an instance of that concrete class.
When implementing the SecureBlackboxStream interface's properties and methods, they must behave as described below. If the concrete class's implementation does not behave as expected, undefined behavior may occur.
Properties | |
CanRead |
Whether the stream supports reading.
bool CanRead() { return true; } |
CanSeek |
Whether the stream supports seeking.
bool CanSeek() { return true; } |
CanWrite |
Whether the stream supports writing.
bool CanWrite() { return true; } |
Length |
Gets the length of the stream, in bytes.
int64 GetLength() = 0; |
Methods | |
Close |
Closes the stream, releasing all resources currently allocated for it.
void Close() {} This method is called automatically when a SecureBlackboxStream object is deleted. |
Flush |
Forces all data held by the stream's buffers to be written out to storage.
int Flush() { return 0; } Must return 0 if flushing is successful; or -1 if an error occurs or the stream is closed. If the stream does not support writing, this method must do nothing and return 0. |
Read |
Reads a sequence of bytes from the stream and advances the current position within the stream by the number of bytes read.
int Read(void* buffer, int count) = 0; Buffer specifies the buffer to populate with data from the stream. Count specifies the number of bytes that should be read from the stream. Must return the total number of bytes read into Buffer; this may be less than Count if that many bytes are not currently available, or 0 if the end of the stream has been reached. Must return -1 if an error occurs, if reading is not supported, or if the stream is closed. |
Seek |
Sets the current position within the stream based on a particular point of origin.
int64 Seek(int64 offset, int seekOrigin) = 0; Offset specifies the offset in the stream to seek to, relative to SeekOrigin. Valid values for SeekOrigin are:
Must return the new position within the stream; or -1 if an error occurs, if seeking is not supported, or if the stream is closed (however, see note below). If -1 is returned, the current position within the stream must remain unchanged. Note: If the stream is not closed, it must always be possible to call this method with an Offset of 0 and a SeekOrigin of 1 to obtain the current position within the stream, even if seeking is not otherwise supported. |
Write |
Writes a sequence of bytes to the stream and advances the current position within the stream by the number of bytes written.
int Write(const void* buffer, int count) = 0; Buffer specifies the buffer with data to write to the stream. Count specifies the number of bytes that should be written to the stream. Must return the total number of bytes written to the stream; this may be less than Count if that many bytes could not be written. Must return -1 if an error occurs, if writing is not supported, or if the stream is closed. |
Config Settings (SFTPClient Class)
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
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. |
Base Config Settings
You can switch this property off to improve performance if your project only uses known, good private keys.
Supported values are:
off | No caching (default) | |
local | Local caching | |
global | Global caching |
This setting only applies to sessions negotiated with TLS version 1.3.
Supported values are:
file | File | |
console | Console | |
systemlog | System Log (supported for Android only) | |
debugger | Debugger (supported for VCL for Windows and .Net) |
Supported values are:
time | Current time | |
level | Level | |
package | Package name | |
module | Module name | |
class | Class name | |
method | Method name | |
threadid | Thread Id | |
contenttype | Content type | |
content | Content | |

Supported filter names are:
exclude-package | Exclude a package specified in the value | |
exclude-module | Exclude a module specified in the value | |
exclude-class | Exclude a class specified in the value | |
exclude-method | Exclude a method specified in the value | |
include-package | Include a package specified in the value | |

none | No flush (caching only) | |
immediate | Immediate flush (real-time logging) | |
maxcount | Flush cached entries upon reaching LogMaxEventCount entries in the cache. |
Supported values are:
none | None (by default) | |
fatal | Severe errors that cause premature termination. | |
error | Other runtime errors or unexpected conditions. | |
warning | Use of deprecated APIs, poor use of API, 'almost' errors, other runtime situations that are undesirable or unexpected, but not necessarily "wrong". | |

debug | Detailed information on flow of through the system. | |
trace | More detailed information. |
The default value of this setting is 100.
none | No rotation | |
deleteolder | Delete older entries from the cache upon reaching LogMaxEventCount | |
keepolder | Keep older entries in the cache upon reaching LogMaxEventCount (newer entries are discarded) |
Supported Values:
certificate | Enables caching of certificates. |
crl | Enables caching of Certificate Revocation Lists (CRLs). |
ocsp | Enables caching of OCSP (Online Certificate Status Protocol) responses. |
Example (default value):
PKICache=certificate,crl,ocsp
In this example, the component caches certificates, CRLs, and OCSP responses.
The default value is an empty string - no cached PKI data is stored on disk.
Example:
PKICachePath=C:\Temp\cache
In this example, the cached PKI data is stored in the C:\Temp\cache directory.
Supported values are:
none | No static DNS rules (default) | |
local | Local static DNS rules | |
global | Global static DNS rules |
This setting only applies to certificates originating from a Windows system store.
The property accepts comma-separated values where the first descriptor name is used when the OID is mapped, and subsequent values act as aliases for parsing.
Syntax:
Config("XMLRDNDescriptorName[OID]=PrimaryName,Alias1,Alias2");
Where:
OID: The Object Identifier from the certificate's IssuerRDN or SubjectRDN that you want to map.
PrimaryName: The main descriptor name used in the XML signature when the OID is encountered.
Alias1, Alias2, ...: Optional alternative names recognized during parsing.
Usage Examples:
Map OID 2.5.4.5 to SERIALNUMBER:
Config("XMLRDNDescriptorName[2.5.4.5]=SERIALNUMBER");
Map OID 1.2.840.113549.1.9.1 to E, with aliases EMAIL and EMAILADDRESS:
Config("XMLRDNDescriptorName[1.2.840.113549.1.9.1]=E,EMAIL,EMAILADDRESS");
Trappable Errors (SFTPClient Class)
Error Handling (C++)
Call the GetLastErrorCode() method to obtain the last called method's result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. Known error codes are listed below. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.
