Struct secureblackbox::FTPClient

Properties Methods Events Config Settings Errors

The FTPClient struct provides client-side functionality for FTP and FTPS protocols.

Syntax

secureblackbox::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 tls_settings property to adjust this setting.
If your server requires you to authenticate with a certificate, you can provide one via the tls_client_chain 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 trusted_certificates and known_certificates collections.
FTP protocol includes its own set of settings, such as passive_mode, encrypt_data_channel, or adjust_pasv_address. These may be configured on this stage, or later into the connection.
In some network environments, you may also need to make adjustments to socket_settings 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 (upload_file or upload_bytes), file downloads (download_file, download_bytes), and directory operations (list_dir, make_dir).

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. on_progress event fires periodically during the transfer operation to let you know of the operation progress. on_control_send and on_control_receive report the protocol communication log. on_file_operation and on_file_operation_result report the start and completion of an individual transfer operation within a multi-file transfer call (such as upload_files).

Object Lifetime

The new() method returns a mutable reference to a struct instance. The object itself is kept in the global list maintained by SecureBlackbox. Due to this, the FTPClient struct cannot be disposed of automatically. Please, call the dispose(&mut self) method of FTPClient when you have finished using the instance.

account_info property (FTPClient Struct)

Parameters for the ACCT command.

Syntax

fn account_info(&self ) -> Result<String, SecureBlackboxError> 
fn set_account_info(&self, value : &str) ->  Option<SecureBlackboxError> 
fn set_account_info_ref(&self, value : &String) ->  Option<SecureBlackboxError>

Default Value

Remarks

Specifies the parameter for ACCT command. If AccountInfo is set, the client automatically sends ACCT command to the server during authentication.

Data Type

String

adjust_pasv_address property (FTPClient Struct)

Enables or disables automatic adjustment of passive-mode addresses.

Syntax

fn adjust_pasv_address(&self ) -> Result<bool, SecureBlackboxError> 
fn set_adjust_pasv_address(&self, value : bool) ->  Option<SecureBlackboxError>

Default Value

true

Remarks

Occasional NAT'ed servers misbehave by returning local IP addresses in their PASV mode offers, which are not reachable from the outer network. Set this property to true to make the struct enforce data connections to the same address as the control connection uses.

Note that sometimes (typically, with multi-faced FTP services aka FTP Clouds) you may need to disable this property to make the transfers work right.

Default Value

Remarks

This property controls the size of the following arrays:

blocked_cert_bytes
blocked_cert_handle

The array indices start at 0 and end at blocked_cert_count - 1.

Data Type

i32

external_crypto_key_id property (FTPClient Struct)

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

Syntax

fn external_crypto_key_id(&self ) -> Result<String, SecureBlackboxError> 
fn set_external_crypto_key_id(&self, value : &str) ->  Option<SecureBlackboxError> 
fn set_external_crypto_key_id_ref(&self, value : &String) ->  Option<SecureBlackboxError>

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 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 external_crypto_key_secret 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";

Data Type

String

3   // AllOCSP
4   // AllCRLAndOCSP
5   // AnyCRL
6   // AnyOCSP
7   // AnyCRLOrOCSP
8   // AnyOCSPOrCRL

Default Value

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`	All provided CRL endpoints will be checked, and all checks must succeed.
crcAllOCSP	`3`	All provided OCSP endpoints will be checked, and all checks must succeed.
crcAllCRLAndOCSP	`4`	All provided CRL and OCSP endpoints will be checked, and all checks must succeed.
crcAnyCRL	`5`	All provided CRL endpoints will be checked, and at least one check must succeed.
crcAnyOCSP	`6`	All provided OCSP endpoints will be checked, and at least one check must succeed.
crcAnyCRLOrOCSP	`7`	All provided CRL and OCSP endpoints will be checked, and at least one check must succeed. CRL endpoints are checked first.
crcAnyOCSPOrCRL	`8`	All provided CRL and OCSP endpoints will be checked, and at least one check must succeed. OCSP endpoints are checked first.

This setting controls the way the revocation checks are performed for every certificate in the chain. 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 the faster OCSP route and only demand one source to succeed) is a good choice for most typical validation environments. The "crcAll*" modes are much stricter, and may be used in scenarios where bulletproof validity information is essential.

NOTE: If no CRL or OCSP endpoints are provided by the CA, the revocation check will be considered successful. This is because the CA chose not to supply revocation information for its certificates, meaning they are considered irrevocable.

NOTE: Within each of the above settings, if any retrieved CRL or OCSP response indicates that the certificate has been revoked, the revocation check fails.

  fn on_control_receive(&self, sender : FTPClient, e : &mut FTPClientControlReceiveEventArgs);
}

impl <'a> FTPClient<'a> {
  pub fn on_control_receive(&self) -> &'a dyn FTPClientControlReceiveEvent;
  pub fn set_on_control_receive(&mut self, value : &'a dyn FTPClientControlReceiveEvent);
  ...
}

Remarks

TextLine contains the data that was received, which would typically contain a reply to a command (e.g. 200 Command OK).

Syntax

// FTPClientControlSendEventArgs carries the FTPClient ControlSend event's parameters.
pub struct FTPClientControlSendEventArgs {
  fn text_line(&self) -> &String
}

// FTPClientControlSendEvent defines the signature of the FTPClient ControlSend event's handler function.
pub trait FTPClientControlSendEvent {
  fn on_control_send(&self, sender : FTPClient, e : &mut FTPClientControlSendEventArgs);
}

impl <'a> FTPClient<'a> {
  pub fn on_control_send(&self) -> &'a dyn FTPClientControlSendEvent;
  pub fn set_on_control_send(&mut self, value : &'a dyn FTPClientControlSendEvent);
  ...
}

Remarks

TextLine contains the data to be sent, which would typically contain a command issued by the client (e.g. CWD dir).

on_error event (FTPClient Struct)

Syntax

// FTPClientErrorEventArgs carries the FTPClient Error event's parameters.
pub struct FTPClientErrorEventArgs {
  fn error_code(&self) -> i32
  fn description(&self) -> &String
}

// FTPClientErrorEvent defines the signature of the FTPClient Error event's handler function.
pub trait FTPClientErrorEvent {
  fn on_error(&self, sender : FTPClient, e : &mut FTPClientErrorEventArgs);
}

impl <'a> FTPClient<'a> {
  pub fn on_error(&self) -> &'a dyn FTPClientErrorEvent;
  pub fn set_on_error(&mut self, value : &'a dyn FTPClientErrorEvent);
  ...
}

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.

on_external_sign event (FTPClient Struct)

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

Syntax

// FTPClientExternalSignEventArgs carries the FTPClient ExternalSign event's parameters.
pub struct FTPClientExternalSignEventArgs {
  fn operation_id(&self) -> &String
  fn hash_algorithm(&self) -> &String
  fn pars(&self) -> &String
  fn data(&self) -> &String
  fn signed_data(&self) -> &String
  fn set_signed_data(&self, value : &str)

}

impl <'a> FTPClient<'a> {
  pub fn on_external_sign(&self) -> &'a dyn FTPClientExternalSignEvent;
  pub fn set_on_external_sign(&mut self, value : &'a dyn FTPClientExternalSignEvent);
  ...
}

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 struct via the SignedData parameter.

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

The struct 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(); };

on_file_name_change_needed event (FTPClient Struct)

Asks the application for a new file name.

pub struct FTPClientFileNameChangeNeededEventArgs {
  fn file_name(&self) -> &String
  fn set_file_name(&self, value : &str)
  fn set_file_name_ref(&self, value : &String)
  fn force(&self) -> bool

on_tls_cert_needed event (FTPClient Struct)

Fires when a remote TLS party requests a client certificate.

Syntax

// FTPClientTLSCertNeededEventArgs carries the FTPClient TLSCertNeeded event's parameters.
pub struct FTPClientTLSCertNeededEventArgs {
  fn host(&self) -> &String
  fn ca_names(&self) -> &String
}

// FTPClientTLSCertNeededEvent defines the signature of the FTPClient TLSCertNeeded event's handler function.
pub trait FTPClientTLSCertNeededEvent {
  fn on_tls_cert_needed(&self, sender : FTPClient, e : &mut FTPClientTLSCertNeededEventArgs);
}

impl <'a> FTPClient<'a> {
  pub fn on_tls_cert_needed(&self) -> &'a dyn FTPClientTLSCertNeededEvent;
  pub fn set_on_tls_cert_needed(&mut self, value : &'a dyn FTPClientTLSCertNeededEvent);
  ...
}

Remarks

This event fires to notify the implementation that a remote TLS server has requested a client certificate. The Host parameter identifies the host that makes a request, and the CANames parameter (optional, according to the TLS spec) advises on the accepted issuing CAs.

Use the tls_client_chain property in response to this event to provide the requested certificate. Please make sure the client certificate includes the associated private key. Note that you may set the certificates before the connection without waiting for this event to fire.

This event is preceded by the on_tls_handshake event for the given host and, if the certificate was accepted, succeeded by the on_tls_established event.

on_tls_cert_validate event (FTPClient Struct)

This event is fired upon receipt of the TLS server's certificate, allowing the user to control its acceptance.

Syntax

// FTPClientTLSCertValidateEventArgs carries the FTPClient TLSCertValidate event's parameters.
pub struct FTPClientTLSCertValidateEventArgs {
  fn server_host(&self) -> &String
  fn server_ip(&self) -> &String

}

impl <'a> FTPClient<'a> {
  pub fn on_tls_cert_validate(&self) -> &'a dyn FTPClientTLSCertValidateEvent;
  pub fn set_on_tls_cert_validate(&mut self, value : &'a dyn FTPClientTLSCertValidateEvent);
  ...
}

Remarks

This event is fired during a TLS handshake. Use the tls_server_chain property to access the certificate chain. In general, structs may contact a number of TLS endpoints during their work, depending on their configuration.

Accept is assigned in accordance with the outcome of the internal validation check performed by the struct, and can be adjusted if needed.

on_tls_established event (FTPClient Struct)

Fires when a TLS handshake with Host successfully completes.

Syntax

// FTPClientTLSEstablishedEventArgs carries the FTPClient TLSEstablished event's parameters.
pub struct FTPClientTLSEstablishedEventArgs {
  fn host(&self) -> &String
  fn version(&self) -> &String
  fn ciphersuite(&self) -> &String
  fn connection_id(&self) -> &[u8]
  fn abort(&self) -> bool
  fn set_abort(&self, value : bool)
}

// FTPClientTLSEstablishedEvent defines the signature of the FTPClient TLSEstablished event's handler function.

  pub fn on_tls_established(&self) -> &'a dyn FTPClientTLSEstablishedEvent;
  pub fn set_on_tls_established(&mut self, value : &'a dyn FTPClientTLSEstablishedEvent);
  ...
}

Remarks

The struct uses this event to notify the application about a successful completion of a TLS handshake.

The Version, Ciphersuite, and ConnectionId parameters indicate the security parameters of the new connection. Use the Abort parameter if you need to terminate the connection at this stage.

on_tls_handshake event (FTPClient Struct)

Fires when a new TLS handshake is initiated, before the handshake commences.

Syntax

// FTPClientTLSHandshakeEventArgs carries the FTPClient TLSHandshake event's parameters.
pub struct FTPClientTLSHandshakeEventArgs {
  fn host(&self) -> &String
  fn abort(&self) -> bool
  fn set_abort(&self, value : bool)
}

// FTPClientTLSHandshakeEvent defines the signature of the FTPClient TLSHandshake event's handler function.
pub trait FTPClientTLSHandshakeEvent {
  fn on_tls_handshake(&self, sender : FTPClient, e : &mut FTPClientTLSHandshakeEventArgs);
}

impl <'a> FTPClient<'a> {
  pub fn on_tls_handshake(&self) -> &'a dyn FTPClientTLSHandshakeEvent;
  pub fn set_on_tls_handshake(&mut self, value : &'a dyn FTPClientTLSHandshakeEvent);
  ...
}

Remarks

The struct uses this event to notify the application about the start of a new TLS handshake to Host. If the handshake is successful, this event will be followed by the on_tls_established event. If the server chooses to request a client certificate, the on_tls_cert_needed event will also be fired.

on_tls_psk event (FTPClient Struct)

Notifies the application about the PSK key exchange.

Syntax

// FTPClientTLSPSKEventArgs carries the FTPClient TLSPSK event's parameters.
pub struct FTPClientTLSPSKEventArgs {
  fn host(&self) -> &String
  fn hint(&self) -> &String
}

// FTPClientTLSPSKEvent defines the signature of the FTPClient TLSPSK event's handler function.
pub trait FTPClientTLSPSKEvent {
  fn on_tls_psk(&self, sender : FTPClient, e : &mut FTPClientTLSPSKEventArgs);
}

impl <'a> FTPClient<'a> {
  pub fn on_tls_psk(&self) -> &'a dyn FTPClientTLSPSKEvent;
  pub fn set_on_tls_psk(&mut self, value : &'a dyn FTPClientTLSPSKEvent);
  ...
}

Remarks

The struct fires this event to notify the application about the beginning of TLS-PSK key exchange with Host. The Hint parameter may be used by the server to identify the key or service to use. Use the PreSharedKey field of tls_settings to provide the pre-shared key to the component.

on_tls_shutdown event (FTPClient Struct)

Reports the graceful closure of a TLS connection.

Syntax

// FTPClientTLSShutdownEventArgs carries the FTPClient TLSShutdown event's parameters.
pub struct FTPClientTLSShutdownEventArgs {
  fn host(&self) -> &String
}

// FTPClientTLSShutdownEvent defines the signature of the FTPClient TLSShutdown event's handler function.
pub trait FTPClientTLSShutdownEvent {
  fn on_tls_shutdown(&self, sender : FTPClient, e : &mut FTPClientTLSShutdownEventArgs);
}

impl <'a> FTPClient<'a> {
  pub fn on_tls_shutdown(&self) -> &'a dyn FTPClientTLSShutdownEvent;
  pub fn set_on_tls_shutdown(&mut self, value : &'a dyn FTPClientTLSShutdownEvent);
  ...
}

Remarks

This event notifies the application about the closure of an earlier established TLS connection. Note that only graceful connection closures are reported.

Config Settings (FTPClient Struct)

The struct 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 struct, access to these internal properties is provided through the config method.

FTPClient Config Settings

AccountInfo: Provides the value to be used with ACCT command.

Specifies an additional authentication value to be passed to the server with the ACCT command.

AuthCmd: Authorization command to be used to request an explicit SSL session.

Use this property to specify the authorization command that will be used to request an explicit SSL session. The following choices are possible: 0 - Auto, 1 - TLS, 2 - SSL, 3 - TLSP, 4 - TLSC. Different servers support different commands, so in most cases it is a good idea to set this property to 0.

CachedCRLMaxAge: Specifies the maximum age of a cached CRL.

Use this setting to specify the maximum number of seconds that may pass since a CRL was added to the global cache. When the cached CRL is older than this value, it is disregarded and a new CRL should be fetched.

The default value is 0, which disables the absolute CRL age check. See RevocationCacheAgePolicy for configuring this setting together with the related cached revocation freshness settings.

CachedCRLMaxAgeRatio: Specifies the maximum age of a cached CRL as a percentage of its remaining lifetime.

Use this setting to specify the percentage of the CRL's remaining lifetime, measured from the time the CRL was added to the global cache to the CRL's NextUpdate. When this portion of the remaining lifetime has passed, the cached CRL is disregarded and a new CRL should be fetched.

The default value is 0, which disables the CRL ratio check. Values are interpreted in the 0..100 range. See RevocationCacheAgePolicy for configuring this setting together with the related cached revocation freshness settings.

CachedCRLOverlapTime: Specifies the time period before a cached CRL's NextUpdate when it is considered stale and must be refreshed.

Use this setting to specify the number of seconds before the NextUpdate time at which the cached CRL should be disregarded, and a new CRL should be fetched.

The default value is 0, which disables the CRL overlap check. See RevocationCacheAgePolicy for configuring this setting together with the related cached revocation freshness settings.

This setting is evaluated independently from CachedCRLMaxAge and CachedCRLMaxAgeRatio. If several cached CRL freshness settings are enabled, the cached CRL is used only if it satisfies all of them.

CachedOCSPResponseMaxAge: Specifies the maximum age of a cached OCSP response.

Use this setting to specify the maximum number of seconds that may pass since an OCSP response was added to the global cache. When the cached OCSP response is older than this value, it is disregarded and a new OCSP response should be fetched.

The default value is 0, which disables the absolute OCSP response age check. This setting is also used to limit open-ended OCSP responses that do not have NextUpdate. See RevocationCacheAgePolicy for configuring this setting together with the related cached revocation freshness settings.

CachedOCSPResponseMaxAgeRatio: Specifies the maximum age of a cached OCSP response as a percentage of its remaining lifetime.

Use this setting to specify the percentage of the OCSP response's remaining lifetime, measured from the time the OCSP response was added to the global cache to the response's NextUpdate. When this portion of the remaining lifetime has passed, the cached OCSP response is disregarded and a new OCSP response should be fetched.

The default value is 0, which disables the OCSP response ratio check. Values are interpreted in the 0..100 range. Open-ended OCSP responses without NextUpdate ignore this setting; use CachedOCSPResponseMaxAge to limit their age. See RevocationCacheAgePolicy for configuring this setting together with the related cached revocation freshness settings.

CachedOCSPResponseOverlapTime: Specifies the time period before a cached OCSP response's NextUpdate when it is considered stale and must be refreshed.

Use this setting to specify the number of seconds before the NextUpdate time at which the cached OCSP response should be disregarded, and a new OCSP response should be fetched.

The default value is 0, which disables the OCSP response overlap check. See RevocationCacheAgePolicy for configuring this setting together with the related cached revocation freshness settings.

This setting is evaluated independently from CachedOCSPResponseMaxAge and CachedOCSPResponseMaxAgeRatio. If several cached OCSP response freshness settings are enabled, the cached OCSP response is used only if it satisfies all of them.

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: Set this to true to avoid sending QUIT command on session closure.

Set this property to true to tell the component not to send the QUIT command when closing the connection.

ConcurrentConnections: Number of simultaneous connections for download.

The maximum number of concurrent connections that may be opened for download. This feature is not available if the server does not support file size requests.

ControlChannelLog: Returns the control channel connection log.

Use this setting to retrieve the control channel connection log, similar to the logs produced by typical FTP clients and servers. Any sensitive data, such as passwords, will be hidden.

CopyMode: Tunes up the post-transfer action for batch uploads.

Use this setting to adjust the post-transfer action for files that are uploaded or downloaded as part of a batch.

The following values are supported:

0 (the default setting) - no post-transfer action.
1 - delete each file immediately after it has been transferred to the destination system.
2 - delete all the original files after all the files have been transferred to the destination system.

The difference between modes 1 and 2 is about error management. In the latter case, any (and all) files will only be deleted if the entire batch has been transferred successfully. Any transfer error that happens in the middle cancels the deletion.

In the former case, each file is deleted right after it has been transferred, independently of the outcome of transfer of other items in the batch.

Note that this setting only applies to batch (multi-file_ transfers. It has no effect on single-file transfers.

DataPort: Sets a specific listening port for active mode data connection.

Use this property to provide a specific listening port to be used for data transfer.

DataPortRangeFilter: Provides a flexible mechanism to set multiple active mode data port ranges.

Use this property to provide multiple data port ranges to be used for active mode transfers. This configuration setting accepts a comma-separated list of ranges or individual port numbers. Make sure that all the port ranges are mutually exclusive and none of any two ranges intersect. Example: 1500,1505-1512,1520,1521-1531.

DataPortRangeFrom: Sets the lower boundary for Active mode data port range.

This setting specifies the lower boundary for the listening port range to be used for data transfers in active mode.

DataPortRangeTo: Sets the upper boundary for Active mode data port range.

This setting specifies the upper boundary for the listening port range to be used for data transfers in active mode.

DeltaCRLPreference: Specifies whether complete or delta CRLs are preferred.

Use this setting to specify which CRL type should be preferred during TLS certificate revocation checks.

The default value is dcrlpPreferDelta (0).

Supported values:

dcrlpPreferDelta (0): retrieve and use delta CRLs when available, falling back to complete CRLs when needed.
dcrlpPreferComplete (1): try complete CRLs first, and use delta CRLs only if complete CRLs cannot be retrieved.

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.

EvaluateSystemTrust: Enables or disables usage of the platform's built-in trust validation facilities.

Enable this property to delegate the chain validation to the operating system's native trust evaluation mechanism (e.g. SecTrustEvaluate on Apple platforms). This functionality is currently available on macOS and iOS systems only. This property is enabled by default.

EventOrigin: Indicates the channel that has fired the event.

Check this read-only property in event handlers to identify whether the event originates from the FTP protocol's control or data channel. While some events are channel-independent (FileOperation, ListEntry), and some other are explicitly bound to the control channel (ControlSend, ControlReceive), some events may be thrown from either. Two examples of such events are CertificateValidate and RemoteSign. The property can be set to one of the following values: feoUnknown (0), feoControl (1), feoData (2).

ExtHOSTSupported: Whether HOST extension is supported.

Use this read-only property to check whether the FTP server supports HOST command.

ExtMDTMSupported: Whether MDTM extension is supported.

Use this read-only property to check whether the FTP server supports MDTM command. The MDTM command is used to determine file modification date.

ExtMFMTSupported: Whether MFMT extension is supported.

Use this read-only property to check whether the FTP server supports MFMT (Modify Fact: Modification Time) command.

ExtMLSTSupported: Whether MLST extension is supported.

Use this read-only property to check whether the FTP server supports MLST command. This command lists the directory contents on the server, although it is different from the LIST command. In particular, MLST reply has a strictly defined format.

ExtOPTSUTF8Supported: Whether OPTS UTF8 extension is supported.

Use this read-only property to check whether the FTP server supports OPTS UTF8 ON command. This command switches the server to UTF8.

ExtRESTSupported: Whether REST extension is supported.

Use this read-only property to check whether the FTP server supports REST (RESTART) command.

ExtSIZESupported: Whether SIZE extension is supported.

Use this read-only property to check whether the FTP server supports SIZE command. This command returns file size.

ExtXCRCSupported: Whether XCRC extension is supported.

Use this read-only property to check whether the FTP server supports XCRC command. It calculates a CRC checksum of the file to check its integrity during transfer.

ExtXMD5Supported: Whether XMD5 extension is supported.

Use this read-only property to check whether the FTP server supports XMD5 command. It calculates an MD5 checksum of a file to check its integrity during transfer.

ExtXSHA1Supported: TBD.

TBD

FTPBufferSize: Buffer size in binary mode.

The size of the memory buffer used for data transfer in binary mode. Changing the buffer size may increase (or, on the contrary, decrease) the speed of file download/upload.

FTPTextBufferSize: Buffer size in text mode.

The size of the memory buffer used for data transfer in text mode. Changing the buffer size may increase (or, on the contrary, decrease) the speed of file download/upload.

IgnoreSystemTrust: Whether trusted Windows Certificate Stores should be treated as trusted.

Specifies whether, during chain validation, the struct should respect the trust to CA certificates as configured in the operating system. In Windows this effectively defines whether the struct should trust the certificates residing in the Trusted Root Certification Authorities store.

If IgnoreSystemTrust is True, certificates residing in the trusted root store are treated as if they are known, rather than trusted. Only certificates provided via other means (such as the trusted_certificates property) are considered trusted.

ListenTimeout: Listening socket timeout.

The maximum time during which the listening socket will be opened in the active mode. If there is no connection request from the server during this time, the transfer operation will be canceled.

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. Defines the local newline convention.

Contains character string for the end of string indication used on the local machine. During file upload all the LocalNewLineConvention line endings are converted to newline endings used on the server. Correspondingly, for all downloaded files line endings are replaced with LocalNewLineConvention line endings. Line ending conventions are only used in text transfer mode.

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. Defines the local newline convention.

MinSizeForConcurrentDownload: Files bigger than this size will be downloaded concurrently.

The minimum size of the file for which the concurrent download is used. The value of ConcurrentConnections property is ignored for smaller files.

ModeZ: Enables or disables data compression.

Use this setting to enable to disable Mode Z (data compression).

Options: Various FTP options.

Various options of FTP connection.

RevocationCacheAgePolicy: Specifies a preset policy for cached CRL and OCSP response freshness settings.

Use this setting to configure all cached revocation freshness settings at once. The default value is Disabled.

Supported values are case-insensitive:


Disabled	Sets CachedCRLOverlapTime, CachedOCSPResponseOverlapTime, CachedCRLMaxAge, CachedOCSPResponseMaxAge, CachedCRLMaxAgeRatio, and CachedOCSPResponseMaxAgeRatio to 0. This value is the default. It only disables the cache-age freshness policy; it does not disable revocation checking or use of the revocation cache.
Default	Applies the component default freshness settings. For this component, Default is equivalent to Disabled.
Short	Uses crl:43200;50;300,ocsp:1800;50;300. This means: CRL maximum age 12 hours, CRL age ratio 50%, CRL overlap 5 minutes; OCSP response maximum age 30 minutes, OCSP response age ratio 50%, OCSP response overlap 5 minutes.
Long	Uses crl:518400;50;3600,ocsp:21600;50;3600. This means: CRL maximum age 6 days, CRL age ratio 50%, CRL overlap 1 hour; OCSP response maximum age 6 hours, OCSP response age ratio 50%, OCSP response overlap 1 hour.
N	Interprets N as an integer number of seconds. The overlap settings are set to N seconds, CRL maximum age is set to N * 144, OCSP response maximum age is set to N * 6, and both ratio settings are set to 50.
crl:<maxAge>;<ratio>;<overlap>,ocsp:<maxAge>;<ratio>;<overlap>	Sets the CRL and OCSP response freshness values explicitly.

Ratios must be in the 0..100 range. Maximum age and overlap values must be non-negative. Short and Long are time-scale profiles: Long allows older cached revocation information by increasing maximum ages, but also uses a larger pre-expiry safety margin by increasing overlap times. For individual CachedCRLOverlapTime, CachedOCSPResponseOverlapTime, CachedCRLMaxAge, CachedOCSPResponseMaxAge, CachedCRLMaxAgeRatio, and CachedOCSPResponseMaxAgeRatio settings, a value of 0 disables the corresponding freshness check. The individual settings remain available for advanced configuration and can be used after this setting to override specific values.

StaticDNS: Specifies whether static DNS rules should be used.

Set this property to enable or disable static DNS rules for the struct. Works only if UseOwnDNSResolver is set to true.

Supported values are:


none		No static DNS rules (default)
local		Local static DNS rules
global		Global static DNS rules

StaticIPAddress[domain]: Gets or sets an IP address for the specified domain name.

Use this property to get or set an IP address for the specified domain name in the internal (of the struct) 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 divided 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 struct is set to "local", the property returns/restores the rules from/to the internal storage of the struct. If StaticDNS of the struct 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.

TempPath: Path for storing temporary files.

This setting specifies an absolute path to the location on disk where temporary files are stored. This setting is supported only in the Java edition for all applicable signing components except PDFSigner, where this limitation does not apply.

TLSCiphersuites: Returns the list of ciphersuites activated in the component for the current session.

Check this property to enumerate the list of TLS ciphersuites enabled in the component. A good place to do that is OnTLSHandshake event handler.

TLSExtensions: TBD.

TBD

TLSGroups: Returns the list of TLS key exchange groups enabled in the component.

Check this property to enumerate the list of TLS key exchange groups enabled in the component.

TLSLayerKeepAlives: Enables or disables keep alive signals on the TLS layer.

Normally FTP environments choose FTP-level keep-alive commands (NOOP). However, in some cases (firewalls, buggy servers) it may be necessary to implement keep-alives at lower level. Use this setting to enable TLS-layer keep-alive packets.

TLSPeerExtensions: TBD.

TBD

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

Use this property to limit the search of cached 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 structs.

TLSSessionLifetime: Specifies lifetime in seconds of the cached TLS session.

Use this property to specify how much time the TLS session should be kept in the session cache. After this time, the session expires and will be automatically removed from the cache. Default value is 300 seconds (5 minutes).

TLSSessionPurgeInterval: Specifies how often the session cache should remove the expired TLS sessions.

Use this property to specify the time interval of purging the expired TLS sessions from the session cache. Default value is 60 seconds (1 minute).

TLSVersions: Returns the list of TLS versions enabled in the component.

Check this property to obtain the list of TLS versions enabled in the component, as an integer bitmask.

TolerateMinorChainIssues: Whether to tolerate minor chain issues.

This parameter controls whether the chain validator should tolerate minor technical issues when validating the chain. Those are:

CA, revocation source, TLS key usage requirements are not mandated

The AuthorityKeyID extension in CRL- and certificate-issuing CAs are ignored (helps with incorrectly renewed certificates)
Basic constraints and name constraints of CA certificates are ignored
Some weaker algorithms are tolerated

TransferKeepAliveInterval: Keep-alive interval for the data channel transfers.

FTPClient may be configured to send occasional NOOP commands on the control channel to circumvent control channel closures by firewalls due to inactivity. This setting sets the period, in milliseconds, after which another NOOP request is sent. The default value of this property is 0, which stands for no NOOP requests.

TransferTimeout: Timeout for data transfer in active mode.

In active mode, specifies a time period that a client should wait for incoming data connection (when file or directory listing is to be transferred). If no data connection is accepted during this period, the data connection will be cancelled.

UseCRLObjectCaching: Specifies whether reuse of loaded CRL objects is enabled.

This setting enables or disables the caching of CRL objects. When set to true (the default value), the system checks if a CRL object is already loaded in memory before attempting to load a new instance. If the object is found, the existing instance is reused, and its reference count is incremented to track its usage. When the reference count reaches zero, indicating that no references to the object remain, the system will free the object from memory. This setting enhances performance by minimizing unnecessary object instantiation and promotes efficient memory management, particularly in scenarios where CRL objects are frequently used.

UseInternalRandom: Switches between SecureBlackbox-own and platform PRNGs.

Allows to switch between internal/native PRNG implementation and the one provided by the platform.

UseLegacyAdESValidation: Enables legacy AdES validation mode.

Use this setting to switch the AdES component to the validation approach that was used in SBB 2020/SBB 2022 (less attention to temporal details).

UseOCSPResponseObjectCaching: Specifies whether reuse of loaded OCSP response objects is enabled.

This setting enables or disables the caching of OCSP response objects. When set to true (the default value), the system checks if a OCSP response object is already loaded in memory before attempting to load a new instance. If the object is found, the existing instance is reused, and its reference count is incremented to track its usage. When the reference count reaches zero, indicating that no references to the object remain, the system will free the object from memory. This setting enhances performance by minimizing unnecessary object instantiation and promotes efficient memory management, particularly in scenarios where OCSP response objects are frequently used.

UseOwnDNSResolver: Specifies whether the client components should use own DNS resolver.

Set this global property to false to force all the client components to use the DNS resolver provided by the target OS instead of using own one.

UseSharedSystemStorages: Specifies whether the validation engine should use a global per-process copy of the system certificate stores.

Set this global property to false to make each validation run use its own copy of system certificate stores.

This is an internal setting. Please do not use it unless instructed by the support team.

UseSystemOAEPAndPSS: Enforces or disables the use of system-driven RSA OAEP and PSS computations.

This global setting defines who is responsible for performing RSA-OAEP and RSA-PSS computations where the private key is stored in a Windows system store and is exportable. If set to true, SBB will delegate the computations to Windows via a CryptoAPI call. Otherwise, it will export the key material and perform the computations using its own OAEP/PSS implementation.

This setting only applies to certificates originating from a Windows system store.

UseSystemRandom: Enables or disables the use of the OS PRNG.

Use this global property to enable or disable the use of operating system-driven pseudorandom number generation.

XMLRDNDescriptorName[OID]: Defines an OID mapping to descriptor names for the certificate's IssuerRDN or SubjectRDN.

This property defines custom mappings between Object Identifiers (OIDs) and descriptor names. This mapping specifies how the certificate's issuer and subject information (ds:IssuerRDN and ds:SubjectRDN elements respectively) are represented in XML signatures.

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.

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");

XMLRDNDescriptorPriority[OID]: Specifies the priority of descriptor names associated with a specific OID.

This property specifies the priority of descriptor names associated with a specific OID that allows to reorder descriptors in the ds:IssuerRDN and ds:SubjectRDN elements during signing.

XMLRDNDescriptorReverseOrder: Specifies whether to reverse the order of descriptors in RDN.

Specifies whether to reverse the order of descriptors in the ds:IssuerRDN and ds:SubjectRDN elements during XML signing. By default, this property is set to true (as specified in RFC 2253, 2.1).
