FTPClient Class
Properties Methods Events Configuration Settings Errors
The FTPClient class provides client-side functionality for FTP and FTPS protocols.
Syntax
FTPClient
Remarks
FTPClient provides client-side support for the FTP (File Transfer Protocol) and FTPS (FTP-over-SSL) protocols. The FTPS protocol allows you to securely perform file transfer operations with a remote server over Transport Layer Security (TLS).
Note: TLS is a successor to the now deprecated SSL protocol, although the latter abbreviation is still widely used.
FTPClient is typically used in the following scenario:
- Setting up the connection parameters
- Connecting to the server and signing in
- Performing file transfer operations
- Closing the connection
Setting up the parameters
When working with FTP or FTP-over-TLS service you will often need to tune up several classes of settings:- Login credentials: these can be tuned up via the Username and Password properties.
- TLS settings: these includes the TLS mode: explicit, implicit, or no TLS. You must get this setting right; otherwise you may not be able to connect. Use TLSSettings property to adjust this setting.
- If your server requires you to authenticate with a certificate, you can provide one via the ClientChain property.
- FTPClient validates the server certificate against the local security settings. If your server uses a custom or non-public PKI, you may need to provide the required trust anchors and CA certificates via the TrustedCertificates and KnownCertificates collections.
- FTP protocol includes its own set of settings, such as PassiveMode, EncryptDataChannel, or AdjustPasvAddress. These may be configured on this stage, or later into the connection.
- In some network environments, you may also need to make adjustments to SocketSettings and Proxy.
Connecting to the server and signing in
Call Connect to open the connection to the server. The component will use the provided credentials to sign you in automatically.Performing file transfer operations
FTPClient offers the full set of FTP operations. These include file uploads (UploadFile or UploadBytes), file downloads (DownloadFile, DownloadBytes), and directory operations (ListDir, MakeDir).Note that unlike SFTP, FTP only supports one transfer operation at a time. An ongoing operation should be completed or aborted before a new one can be started.
Closing the connection
Use Disconnect to close the FTP connection.Useful info
During its work FTPClient communicates back via events. Progress event fires periodically during the transfer operation to let you know of the operation progress. ControlSend and ControlReceive report the protocol communication log. FileOperation and FileOperationResult report the start and completion of an individual transfer operation within a multi-file transfer call (such as UploadFiles).Property List

ExternalCryptoKeyID Property (FTPClient Class)
The ID of the pre-shared key used for DC request authentication.
Syntax
QString GetExternalCryptoKeyID();
int SetExternalCryptoKeyID(QString qsExternalCryptoKeyID);
Default Value
""
Remarks
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 extra protection layer for the protocol and diminishes the risk of private key becoming abused by foreign parties. Use this property to provide the pre-shared key identifier, and use ExternalCryptoKeySecret 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";

Possible Values
CRC_NONE(0),
CRC_AUTO(1),
CRC_ALL_CRL(2),
CRC_ALL_OCSP(3),
CRC_ALL_CRLAND_OCSP(4),
CRC_ANY_CRL(5),
CRC_ANY_OCSP(6),
CRC_ANY_CRLOR_OCSP(7),
CRC_ANY_OCSPOR_CRL(8)
Default Value
1
Remarks
Specifies the kind(s) of revocation check to perform.
Revocation checking is necessary to ensure the integrity of the chain and obtain up-to-date certificate validity and trustworthiness information.
crcNone (0) | No revocation checking |
crcAuto (1) | Automatic mode selection. Currently this maps to crcAnyOCSPOrCRL, but it may change in the future. |
crcAllCRL (2) | Check all provided CRL endpoints for all chain certificates. |
crcAllOCSP (3) | Check all provided OCSP endpoints for all chain certificates. |
crcAllCRLAndOCSP (4) | Check all CRL and OCSP endpoints for all chain certificates. |
crcAnyCRL (5) | At least one CRL check for every certificate in the chain must succeed. |
crcAnyOCSP (6) | At least one OCSP check for every certificate in the chain must succeed. |
crcAnyCRLOrOCSP (7) | At least one CRL or OCSP check for every certificate in the chain must succeed. CRL endpoints are checked first. |
crcAnyOCSPOrCRL (8) | At least one CRL or OCSP check for every certificate in the chain must succeed. OCSP endpoints are checked first. |
This setting controls the way the revocation checks are performed. Typically certificates come with two types of revocation information sources: CRL (certificate revocation lists) and OCSP responders. CRLs are static objects periodically published by the CA at some online location. OCSP responders are active online services maintained by the CA that can provide up-to-date information on certificate statuses in near real time.
There are some conceptual differences between the two. CRLs are normally larger in size. Their use involves some latency because there is normally some delay between the time when a certificate was revoked and the time the subsequent CRL mentioning that is published. The benefits of CRL is that the same object can provide statuses for all certificates issued by a particular CA, and that the whole technology is much simpler than OCSP (and thus is supported by more CAs).
This setting lets you adjust the validation course by including or excluding certain types of revocation sources from the validation process. The crcAnyOCSPOrCRL setting (give preference to faster OCSP route and only demand one source to succeed) is a good choice for most of typical validation environments. The "crcAll*" modes are much stricter, and may be used in scenarios where bulletproof validity information is essential.
This property is not available at design time.

class FTPClientCertificateValidateEventParams { public: const QString &Address(); bool Accept(); void SetAccept(bool bAccept); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void CertificateValidate(FTPClientCertificateValidateEventParams *e);
// Or, subclass FTPClient and override this emitter function. virtual int FireCertificateValidate(FTPClientCertificateValidateEventParams *e) {...}
Remarks
The class fires this event upon receiving the server's certificate during TLS handshake. The subscriber to this event has to validate the certificate and return its status back to the class using the Accept parameter.
The Address parameter indicates the address of the server the connection is being established to.
This event is fired independently of the AutoValidateCertificates setting. If this setting is false, the event handler (and your code) is responsible for validating the certificate chain and returning the result back to the component through the Accept parameter. Note that setting AutoValidateCertificates to false and not performing any validation inside the handler of this event creates a serious security vulnerability, which can lead to grave consequences.
The exact validation method to use depends on your circumstances, and may range from comparing the certificate to its legit and trusted copy (sometimes called certificate pinning), to fully-fledged chain validation. CertificateValidator component is one of the options to build your chain validation on.
If AutoValidateCertificates is true, the chain has already been validated internally by the component by the time this event fires, and the value of Accept reflects the outcome of that check. You can perform your own, additional validation even when using AutoValidateCertificates mode, and adjust Accept if needed.
ControlReceive Event (FTPClient Class)
Fires when data is received via the control channel.
Syntax
class FTPClientControlReceiveEventParams { public: const QString &TextLine(); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void ControlReceive(FTPClientControlReceiveEventParams *e);
// Or, subclass FTPClient and override this emitter function. virtual int FireControlReceive(FTPClientControlReceiveEventParams *e) {...}
Remarks
TextLine contains the data that was received, which would typically contain a reply to a command (e.g. 200 Command OK).
ControlSend Event (FTPClient Class)
Fires when data is about to be set via the control channel.
Syntax
class FTPClientControlSendEventParams { public: const QString &TextLine(); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void ControlSend(FTPClientControlSendEventParams *e);
// Or, subclass FTPClient and override this emitter function. virtual int FireControlSend(FTPClientControlSendEventParams *e) {...}
Remarks
TextLine contains the data to be sent, which would typically contain a command issued by the client (e.g. CWD dir).
Error Event (FTPClient Class)
Information about errors during data delivery.
Syntax
class FTPClientErrorEventParams { public: int ErrorCode(); const QString &Description(); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void Error(FTPClientErrorEventParams *e);
// Or, subclass FTPClient and override this emitter function. virtual int FireError(FTPClientErrorEventParams *e) {...}
Remarks
The event is fired in case of exceptional conditions during message processing.
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 FTP section.
ExternalSign Event (FTPClient Class)
Handles remote or external signing initiated by the SignExternal method or other source.
Syntax

// To handle, connect one or more slots to this signal. void ExternalSign(FTPClientExternalSignEventParams *e);
// Or, subclass FTPClient and override this emitter function. virtual int FireExternalSign(FTPClientExternalSignEventParams *e) {...}
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 component via SignedData parameter.
OperationId provides a comment about the operation and its origin. It depends on the exact component being used, and may be empty. HashAlgorithm specifies the hash algorithm being used for the operation, and Pars contain algorithm-dependent parameters.
The component uses base16 (hex) encoding for 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 a .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();
};
