FTPClient Module

Properties Methods Events Config Settings Errors

The FTPClient module 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 TLSSettings property to adjust this setting.
If your server requires you to authenticate with a certificate, you can provide one via the TLSClientChain 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).

An example of a scenario where you might want to do that is when intermediary CA certificates are absent from the standard system locations (or when there are no standard system locations), and therefore should be supplied to the class manually.

The purpose of the certificates to be added to this collection is roughly equivalent to that of the Intermediate Certification Authorities system store in Windows.

Do not add trust anchors or root certificates to this collection: add them to TrustedCertificates instead.

- (int)trustedCertCount;
- (void)setTrustedCertCount :(int)newTrustedCertCount;

- (NSData*)trustedCertBytes:(int)trustedCertIndex;

- (long long)trustedCertHandle:(int)trustedCertIndex;
- (void)setTrustedCertHandle:(int)trustedCertIndex :(long long)newTrustedCertHandle;

Default Value

Remarks

Use this property to supply a list of trusted certificates that might be needed for chain validation. An example of a scenario where you might want to do that is when root CA certificates are absent from the standard system locations (or when there are no standard system locations), and therefore should be supplied to the component manually.

The purpose of this certificate collection is largely the same as that of the Windows Trusted Root Certification Authorities system store.

Use this property with extreme care as it directly affects chain verifiability; a wrong certificate added to the trusted list may result in bad chains being accepted, and forfeited signatures being recognized as genuine. Only add certificates that originate from the parties that you know and trust.

Username Property (FTPClient Module)

The connecting user's username (login name).

Syntax

Swift
Objective-C

public var username: String {
  get {...}
  set {...}
}

Swift
Objective-C

public func abort() throws -> Void

- (void)abort;

Remarks

Use this method to abort the previous FTP service command and any associated data transfer.

Acct Method (FTPClient Module)

Sends an Account command.

Syntax

Swift
Objective-C

public func acct(acctInfo: String) throws -> Void

- (void)acct:(NSString*)acctInfo;

Remarks

Some servers require the ACCT command to be sent after signing in to grant access to specific server resources.

Reply codes sometimes allow to differentiate the handling of ACCT command:

when account information is required for login, the response to a successful PASSword command is reply code 332;
if account information is NOT required for login, the reply to a successful PASSword command is 230;
if account information is needed for a command issued later in the dialogue, the server should return a 332 or 532 reply depending on whether it stores (pending receipt of the ACCounT command) or discards the command, respectively.

AppendBytes Method (FTPClient Module)

Appends a byte array to a server-side file.

Syntax

Swift

Some servers expect this command to allow for the control channel to be properly handled by NATs.

Config Method (FTPClient Module)

Sets or retrieves a configuration setting.

Syntax

Swift
Objective-C

public func config(configurationString: String) throws -> String

- (NSString*)config:(NSString*)configurationString;

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.

DeleteFile Method (FTPClient Module)

Deletes a file on the server.

Syntax

Swift
Objective-C

public func deleteFile(remoteFile: String) throws -> Void

- (void)deleteFile:(NSString*)remoteFile;

Remarks

This method sends a DELE command to the server to request deletion of a remote file.

DirExists Method (FTPClient Module)

Checks if a directory exists on the server.

Syntax

Swift
Objective-C

public func dirExists(remoteDir: String) throws -> Bool

- (BOOL)dirExists:(NSString*)remoteDir;

Remarks

Use this method to check if the RemoteDir exists on the server.

The test is performed by attempting to change the current directory to RemoteDir, and checking the response code returned by the server.

Note that this method will return false if the directory does exist but is not accessible for the client (e.g. due to a permission issue).

Disconnect Method (FTPClient Module)

Disconnects from the server.

Syntax

Swift
Objective-C

public func disconnect() throws -> Void

- (void)disconnect;

Remarks

DoAction is a generic method available in every class. It is used to perform an additional action introduced after the product major release. The list of actions is not fixed, and may be flexibly extended over time.

The unique identifier (case insensitive) of the action is provided in the ActionID parameter.

ActionParams contains the value of a single parameter, or a list of multiple parameters for the action in the form of PARAM1=VALUE1;PARAM2=VALUE2;....

DownloadBytes Method (FTPClient Module)

Downloads a file from the server into an array of bytes.

Syntax

Swift
Objective-C

- (void)downloadFile:(NSString*)remoteFile :(NSString*)localFile;

Remarks

Use this method to download RemoteFile into LocalFile.

DownloadFiles Method (FTPClient Module)

Downloads multiple files from the server.

Syntax

Swift
Objective-C

public func downloadFiles(remotePath: String, localDir: String, recursive: Bool, errorHandling: Int32) throws -> Void

- (void)downloadFiles:(NSString*)remotePath :(NSString*)localDir :(BOOL)recursive :(int)errorHandling;

Remarks

Use this method do download a collection of files from the server.

RemotePath can contain a simple mask, a set of masks, or a regular expression. All the files that match the provided rule will be downloaded to LocalDir. 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 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

FileExists Method (FTPClient Module)

Checks if a file exists on the server.

Syntax

Swift
Objective-C

public func fileExists(remoteFile: String) throws -> Bool

- (BOOL)fileExists:(NSString*)remoteFile;

Remarks

Use this method to check if RemoteFile exists in the current remote directory. This method attempts to detect file existence using SIZE and MLST commands first, and falls back to LIST command if they are not available.

Please note that this command only looks for the file in the current directory. To check for existence of a file in a different directory, change to it with ChangeDir command first, then call this method.

GetCurrentDir Method (FTPClient Module)

Returns the server-side current directory.

Syntax

Swift
Objective-C

public func getCurrentDir() throws -> String

- (NSString*)getCurrentDir;

Remarks

Use this method to find out the current directory on the server.

GetFileSize Method (FTPClient Module)

Returns the size of a remote file.

Syntax

Swift
Objective-C

public func getFileSize(remoteFile: String) throws -> Int64

- (long long)getFileSize:(NSString*)remoteFile;

Remarks

Use this method to retrieve the size of a remote file. This method attempts to use SIZE and MLST commands if available, and resorts to LIST command otherwise.

Lists the contents of a remote directory.

Syntax

Swift
Objective-C

public func listDir(includeFiles: Bool, includeDirectories: Bool) throws -> String

- (NSString*)listDir:(BOOL)includeFiles :(BOOL)includeDirectories;

Remarks

Use the IncludeFiles and IncludeDirectories parameters to tune up the output. The output of IncludeFiles also includes symbolic links.

This method returns a human-readable string containing the requested list. It also fires ListEntry for each entry in the list, propagating its details in CurrentListEntry.

This method uses some heuristics internally by choosing the most appropriate listing method among MLSD, NLST, and LIST.

MakeDir Method (FTPClient Module)

Creates a new directory on the server.

Syntax

Swift
Objective-C

public func makeDir(remoteDir: String) throws -> Void

- (void)uploadFiles:(NSString*)localPath :(NSString*)remoteDir :(BOOL)recursive :(int)errorHandling;

Remarks

This method uploads all the files that match the LocalPath criteria to RemoteDir directory on the server. LocalPath accepts a simple mask, a set of masks, or a regular expression. 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 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
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

For each file being uploaded a pair of FileOperation and FileOperationResult events are invoked.

ExternalSign Event (FTPClient 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 onTLSCertNeeded(host: String, caNames: String)

- (void)onTLSCertNeeded:(NSString*)host :(NSString*)CANames;

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 TLSClientChain 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 TLSHandshake event for the given host and, if the certificate was accepted, succeeded by the TLSEstablished event.

TLSCertValidate Event (FTPClient Module)

Syntax

Swift
Objective-C

func onTLSHandshake(host: String, abort: inout Bool)

- (void)onTLSHandshake:(NSString*)host :(int*)abort;

Remarks

The class 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 TLSEstablished event. If the server chooses to request a client certificate, the TLSCertNeeded event will also be fired.

TLSPSK Event (FTPClient Module)

Notifies the application about the PSK key exchange.

Syntax

Swift
Objective-C

func onTLSPSK(host: String, hint: String)

- (void)onTLSPSK:(NSString*)host :(NSString*)hint;

Remarks

The class 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 TLSSettings to provide the pre-shared key to the component.

TLSShutdown Event (FTPClient Module)

Reports the graceful closure of a TLS connection.

Syntax

Swift
Objective-C

func onTLSShutdown(host: String)

- (void)onTLSShutdown:(NSString*)host;

Remarks

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

Certificate Type

Encapsulates an individual X.509 certificate.

Remarks

This type keeps and provides access to X.509 certificate details.

The following fields are available:

Fields

bytes
Data (read-only)
Default Value: ""

Returns the raw certificate data in DER format.

ca
Bool
Default Value: False

Indicates whether the certificate has a CA capability. For the certificate to be considered a CA, it must have its Basic Constraints extension set with the CA indicator enabled.

Set this property when generating a new certificate to have its Basic Constraints extension generated automatically.

caKeyID
Data (read-only)
Default Value: ""

A unique identifier (fingerprint) of the CA certificate's cryptographic key.

Authority Key Identifier is a certificate extension which allows identification of certificates belonging to the same issuer, but with different public keys. It is a de-facto standard to include this extension in all certificates to facilitate chain building.

This setting cannot be set when generating a certificate as it always derives from another certificate property. CertificateManager generates this setting automatically if enough information is available to it: for self-signed certificates, this value is copied from the setting, and for lower-level certificates, from the parent certificate's subject key ID extension.

certType
CertTypes (read-only)
Default Value: 0

Returns the type of the entity contained in the Certificate object.

A Certificate object can contain two types of cryptographic objects: a ready-to-use X.509 certificate, or a certificate request ("an unsigned certificate"). Certificate requests can be upgraded to full certificates by signing them with a CA certificate.

Use the CertificateManager class to load or create new certificate and certificate requests objects.

crlDistributionPoints
String
Default Value: ""

Contains a list of locations of CRL distribution points used to check this certificate's validity. The list is taken from the respective certificate extension.

Use this property when generating a certificate to provide a list of CRL endpoints that should be made part of the new certificate.

The endpoints are provided as a list of CRLF-separated URLs. Note that this differs from the behaviour used in earlier product versions, where the "|" character was used as the location separator.

curve
String
Default Value: ""

Specifies the elliptic curve associated with the certificate's public key. This setting only applies to certificates containing EC keys.

fingerprint
String (read-only)
Default Value: ""

Contains the fingerprint (a hash imprint) of this certificate.

While there is no formal standard defining what a fingerprint is, a SHA1 hash of the certificate's DER-encoded body is typically used.

friendlyName
String (read-only)
Default Value: ""

Contains an associated alias (friendly name) of the certificate. The friendly name is not a property of a certificate: it is maintained by the certificate media rather than being included in its DER representation. Windows certificate stores are one example of media that does support friendly names.

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());

hashAlgorithm
String
Default Value: ""

Provides means to set the hash algorithm to be used in the subsequent operation on the certificate (such as generation or key signing). It is not a property of a certificate; use to find out the hash algorithm that is part of the certificate signature.

Use the , , and properties to get more details about the key the certificate contains.

keyBits
Int32 (read-only)
Default Value: 0

Returns the length of the public key in bits.

This value indicates the length of the principal cryptographic parameter of the key, such as the length of the RSA modulus or ECDSA field. The key data returned by the or property would typically contain auxiliary values, and therefore be longer.

keyFingerprint
String (read-only)
Default Value: ""

Returns a SHA1 fingerprint of the public key contained in the certificate.

Note that the key fingerprint is different from the certificate fingerprint accessible via the property. The key fingeprint uniquely identifies the public key, and so can be the same for multiple certificates containing the same key.

keyUsage
Int32
Default Value: 0

Indicates the purposes of the key contained in the certificate, in the form of an OR'ed flag set.

This value is a bit mask of the following values:


ckuUnknown	`0x00000`	Unknown key usage
ckuDigitalSignature	`0x00001`	Digital signature
ckuNonRepudiation	`0x00002`	Non-repudiation
ckuKeyEncipherment	`0x00004`	Key encipherment
ckuDataEncipherment	`0x00008`	Data encipherment
ckuKeyAgreement	`0x00010`	Key agreement
ckuKeyCertSign	`0x00020`	Certificate signing
ckuCRLSign	`0x00040`	Revocation signing
ckuEncipherOnly	`0x00080`	Encipher only
ckuDecipherOnly	`0x00100`	Decipher only
ckuServerAuthentication	`0x00200`	Server authentication
ckuClientAuthentication	`0x00400`	Client authentication
ckuCodeSigning	`0x00800`	Code signing
ckuEmailProtection	`0x01000`	Email protection
ckuTimeStamping	`0x02000`	Timestamping
ckuOCSPSigning	`0x04000`	OCSP signing
ckuSmartCardLogon	`0x08000`	Smartcard logon
ckuKeyPurposeClientAuth	`0x10000`	Kerberos - client authentication
ckuKeyPurposeKDC	`0x20000`	Kerberos - KDC

Set this property before generating the certificate to propagate the key usage flags to the new certificate.

keyValid
Bool (read-only)
Default Value: False

Returns True if the certificate's key is cryptographically valid, and False otherwise.

ocspLocations
String
Default Value: ""

Locations of OCSP services that can be used to check this certificate's validity in real time, as recorded by the CA.

Set this property before calling the certificate manager's Generate method to propagate it to the new certificate.

The OCSP locations are provided as a list of CRLF-separated URLs. Note that this differs from the behaviour used in earlier product versions, where the "|" character was used as the location separator.

ocspNoCheck
Bool
Default Value: False

Accessor to the value of the certificate's ocsp-no-check extension.

origin
Int32 (read-only)
Default Value: 0

Returns the location that the certificate was taken or loaded from.

policyIDs
String
Default Value: ""

Contains identifiers (OIDs) of the applicable certificate policies.

The Certificate Policies extension identifies a sequence of policies under which the certificate has been issued, and which regulate its usage.

Set this property when generating a certificate to propagate the policies information to the new certificate.

The policies are provided as a list of CRLF-separated entries. Note that this differs from the behaviour used in earlier product versions, where the "|" character was used as the policy element separator.

privateKeyBytes
Data (read-only)
Default Value: ""

Returns the certificate's private key in DER-encoded format. It is normal for this property to be empty if the private key is non-exportable, which, for example, is typical for certificates originating from hardware security devices.

privateKeyExists
Bool (read-only)
Default Value: False

Indicates whether the certificate has a usable private key associated with it. If it is set to True, the certificate can be used for private key operations, such as signing or decryption.

This property is independent from , and can be set to True even if the former is empty. This would imply that the private key is non-exportable, but still can be used for cryptographic operations.

privateKeyExtractable
Bool (read-only)
Default Value: False

Indicates whether the private key is extractable (exportable).

publicKeyBytes
Data (read-only)
Default Value: ""

Contains the certificate's public key in DER format.

This typically would contain an ASN.1-encoded public key value. The exact format depends on the type of the public key contained in the certificate.

qualified
Bool (read-only)
Default Value: False

Indicates whether the certificate is qualified.

This property is set to True if the certificate is confirmed by a Trusted List to be qualified.

qualifiedStatements
QualifiedStatementsTypes
Default Value: 0

Returns a simplified qualified status of the certificate.

qualifiers
String (read-only)
Default Value: ""

A list of qualifiers.

Contains a comma-separated list of qualifier aliases for the certificate, for example QCP-n-qscd,QCWithSSCD.

selfSigned
Bool (read-only)
Default Value: False

Indicates whether the certificate is self-signed (root) or signed by an external CA.

serialNumber
Data
Default Value: ""

Returns the certificate's serial number.

The serial number is a binary string that uniquely identifies a certificate among others issued by the same CA. According to the X.509 standard, the (issuer, serial number) pair should be globally unique to facilitate chain building.

sigAlgorithm
String (read-only)
Default Value: ""

Indicates the algorithm that was used by the CA to sign this certificate.

A signature algorithm typically combines hash and public key algorithms together, such as sha256WithRSAEncryption or ecdsa-with-SHA256.

source
PKISources (read-only)
Default Value: 0

Returns the source (location or disposition) of a cryptographic primitive entity, such as a certificate, CRL, or OCSP response.

subject
String (read-only)
Default Value: ""

The common name of the certificate holder, typically an individual's name, a URL, an e-mail address, or a company name. This is part of a larger set of credentials available via .

subjectAlternativeName
String
Default Value: ""

Returns or sets the value of the Subject Alternative Name extension of the certificate.

Subject alternative names are used to provide additional names that are impractical to store in the main field. For example, it is often used to store all the domain names that a TLS certificate is authorized to protect.

The alternative names are provided as a list of CRLF-separated entries. Note that this differs from the behaviour used in earlier product versions, where the "|" character was used as the element separator.

subjectKeyID
Data
Default Value: ""

Contains a unique identifier of the certificate's cryptographic key.

Subject Key Identifier is a certificate extension which allows a specific public key to be associated with a certificate holder. Typically, subject key identifiers of CA certificates are recorded as respective CA key identifiers in the subordinate certificates that they issue, which facilitates chain building.

The and properties of self-signed certificates typically contain identical values, as in that specific case, the issuer and the subject are the same entity.

subjectRDN
String
Default Value: ""

A list of Property=Value pairs that uniquely identify the certificate holder (subject).

Depending on the purpose of the certificate and the policies of the CA that issued it, the values included in the subject record may differ drastically and contain business or personal names, web URLs, email addresses, and other data.

Example: /C=US/O=Oranges and Apples, Inc./OU=Accounts Receivable/1.2.3.4.5=Value with unknown OID/CN=Margaret Watkins.

valid
Bool (read-only)
Default Value: False

Indicates whether or not the signature over the certificate or the request is valid and matches the public key contained in the CA certificate/request.

validFrom
String
Default Value: ""

The time point at which the certificate becomes valid, in UTC.

validTo
String
Default Value: ""

The time point at which the certificate expires, in UTC.

Constructors

public init(stream: )

Loads the X.509 certificate from a stream. Stream is a stream containing the certificate data.

public init()

Creates a new object with default field values.

CRL Type

Represents a Certificate Revocation List.

Remarks

CRLs store information about revoked certificates, i.e., certificates that have been identified as invalid by their issuing certificate authority (CA) for any number of reasons.

Each CRL object lists certificates from a single CA and identifies them by their serial numbers. A CA may or may not publish a CRL, may publish several CRLs, or may publish the same CRL in multiple locations.

Unlike OCSP responses, CRLs only list certificates that have been revoked. They do not list certificates that are still valid.

The following fields are available:

Fields

bytes
Data (read-only)
Default Value: ""

Returns the raw CRL data in DER format.

caKeyID
Data
Default Value: ""

A unique identifier (fingerprint) of the CA certificate's private key, if present in the CRL.

entryCount
Int32 (read-only)
Default Value: 0

Returns the number of certificate status entries in the CRL.

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.

issuer
String (read-only)
Default Value: ""

The common name of the CRL issuer (CA), typically a company name.

issuerRDN
String (read-only)
Default Value: ""

A collection of information, in the form of [OID, Value] pairs, uniquely identifying the CRL issuer.

location
String (read-only)
Default Value: ""

The URL that the CRL was downloaded from.

nextUpdate
String
Default Value: ""

The planned time and date of the next version of this CRL to be published.

sigAlgorithm
String
Default Value: "0"

The public key algorithm that was used by the CA to sign this CRL.

source
PKISources (read-only)
Default Value: 0

Returns the source (location or disposition) of a cryptographic primitive entity, such as a certificate, CRL, or OCSP response.

tbs
Data (read-only)
Default Value: ""

The to-be-signed part of the CRL (the CRL without the signature part).

thisUpdate
String
Default Value: ""

The date and time at which this version of the CRL was published.

Constructors

public init()

Creates an empty CRL object.

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.

ccatRequestCert	`1`
ccatRequireCert	`2`

ecCurves
String

Provides access to TLS extensions.

forceResumeIfDestinationChanges
Bool
Default Value: False

Whether to force TLS session resumption when the destination address changes.

preSharedIdentity
String
Default Value: ""

Defines the identity used when the PSK (Pre-Shared Key) key-exchange mechanism is negotiated.

preSharedKey
String
Default Value: ""

Contains the pre-shared key for the PSK (Pre-Shared Key) key-exchange mechanism, encoded with base16.

preSharedKeyCiphersuite
String
Default Value: ""

Defines the ciphersuite used for PSK (Pre-Shared Key) negotiation.

renegotiationAttackPreventionMode
RenegotiationAttackPreventionModes
Default Value: 2

Selects the renegotiation attack prevention mechanism.

The following options are available:


crapmCompatible	`0`	TLS 1.0 and 1.1 compatibility mode (renegotiation indication extension is disabled).
crapmStrict	`1`	Renegotiation attack prevention is enabled and enforced.
crapmAuto	`2`	Automatically choose whether to enable or disable renegotiation attack prevention.

revocationCheck
RevocationCheckKinds
Default Value: 1

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.

Constructors

public init()

Creates a new TLSSettings object.

Config Settings (FTPClient 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.

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.

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 retrive 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: 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.

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.

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 class should respect the trust to CA certificates as configured in the operating system. In Windows this effectively defines whether the class 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 TrustedCertificates 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 LocalNewLineConventionline 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.

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 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.

TempPath: Path for storing temporary files.

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

TLSExtensions: TBD.

TBD

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 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.

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).

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
Violation of OCSP issuer requirements are ignored
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.

UseMicrosoftCTL: Enables or disables the automatic use of the Microsoft online certificate trust list.

Enable this property to make the chain validation module automatically look up missing CA certificates in the public Windows Update repository.

UseProxySettingsForDataChannel: Whether the proxy settings should be applied to data channel.

Whether the proxy settings should be applied to data channel.

UseSystemCertificates: Enables or disables the use of the system certificates.

Use this property to tell the chain validation module to automatically look up missing CA certificates in the system certificates. In many cases it is beneficial to switch this property on, as the operating system certificate configuration provides a representative trust framework.

UseUTF8IfAvailable: Upgrade to UTF8 string encoding if the server supports it.

This setting, which is set to true by default, tells the client to activate UTF8 encoding for international strings if the server indicates its support via the UTF8 feature.

HttpVersion: The HTTP version to use in any inner HTTP client components created.

Set this property to 1.0 or 1.1 to indicate the HTTP version that any internal HTTP clients should use.

IgnoreExpiredMSCTLSigningCert: Whether to tolerate the expired Windows Update signing certificate.

It is not uncommon for Microsoft Windows Update Certificate Trust List to be signed with an expired Microsoft certificate. Setting this global property to true makes SBB ignore the expired factor and take the Trust List into account.

ListDelimiter: The delimiter character for multi-element lists.

Allows to set the delimiter for any multi-entry values returned by the component as a string object, such as file lists. For most of the components, this property is set to a newline sequence.

Use this property to provide the desired debug log level.

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".
info		Interesting runtime events (startup/shutdown).
debug		Detailed information on flow of through the system.
trace		More detailed information.

LogMaxEventCount: Specifies the maximum number of events to cache before further action is taken.

Use this property to specify the log event number threshold. This threshold may have different effects, depending on the rotation setting and/or the flush mode.

The default value of this setting is 100.

Use this property to set the log rotation mode. The following values are defined:


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)

MaxASN1BufferLength: Specifies the maximal allowed length for ASN.1 primitive tag data.

This global property limits the maximal allowed length for ASN.1 tag data for non-content-carrying structures, such as certificates, CRLs, or timestamps. It does not affect structures that can carry content, such as CMS/CAdES messages. This is a security property aiming at preventing DoS attacks.

MaxASN1TreeDepth: Specifies the maximal depth for processed ASN.1 trees.

This global property limits the maximal depth of ASN.1 trees that the component can handle without throwing an error. This is a security property aiming at preventing DoS attacks.

OCSPHashAlgorithm: Specifies the hash algorithm to be used to identify certificates in OCSP requests.

This global setting defines the hash algorithm to use in OCSP requests during chain validation. Some OCSP responders can only use older algorithms, in which case setting this property to SHA1 may be helpful.

OldClientSideRSAFallback: Specifies whether the SSH client should use a SHA1 fallback.

Tells the SSH client to use a legacy ssh-rsa authentication even if the server indicates support for newer algorithms, such as rsa-sha-256. This is a backward-compatibility tweak.

ProductVersion: Returns the version of the SecureBlackbox library.

This property returns the long version string of the SecureBlackbox library being used (major.minor.build.revision).

ServerSSLDHKeyLength: Sets the size of the TLS DHE key exchange group.

Use this property to adjust the length, in bits, of the DHE prime to be used by the TLS server.

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).

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.
