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 ClientChain property.
FTPClient validates the server certificate against the local security settings. If your server uses a custom or non-public PKI, you may need to provide the required trust anchors and CA certificates via the TrustedCertificates and KnownCertificates collections.
FTP protocol includes its own set of settings, such as PassiveMode, EncryptDataChannel, or AdjustPasvAddress. These may be configured on this stage, or later into the connection.
In some network environments, you may also need to make adjustments to SocketSettings and Proxy.

Connecting to the server and signing in

Call Connect to open the connection to the server. The component will use the provided credentials to sign you in automatically.

Performing file transfer operations

FTPClient offers the full set of FTP operations. These include file uploads (UploadFile or UploadBytes), file downloads (DownloadFile, DownloadBytes), and directory operations (ListDir, MakeDir).

Note that unlike SFTP, FTP only supports one transfer operation at a time. An ongoing operation should be completed or aborted before a new one can be started.

Closing the connection

Use Disconnect to close the FTP connection.

Useful info

During its work FTPClient communicates back via events. Progress event fires periodically during the transfer operation to let you know of the operation progress. ControlSend and ControlReceive report the protocol communication log. FileOperation and FileOperationResult report the start and completion of an individual transfer operation within a multi-file transfer call (such as UploadFiles).

- (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 component via SignedData parameter.

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

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

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

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

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

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

Progress Event (FTPClient Module)

Reports the data transfer progress.

Syntax

Swift
Objective-C

func onProgress(total: Int64, current: Int64, cancel: inout Bool)

- (void)onProgress:(long long)total :(long long)current :(int*)cancel;

Remarks

This event fires periodically during a file transfer operation to report its progress.

Use the Cancel parameter to terminate the transfer if needed.

TextDataLine Event (FTPClient Module)

Reports next transferred data line.

Syntax

Swift
Objective-C

func onTextDataLine(textLine: String)

- (void)onTextDataLine:(NSString*)textLine;

Remarks

The class fires this event in series when transferring a file in ASCII mode to report each line being transferred.

TLSCertNeeded Event (FTPClient Module)

Fires when a remote TLS party requests a client certificate.

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 (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)

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

Syntax

Swift
Objective-C

func onTLSCertValidate(serverHost: String, serverIP: String, accept: inout Bool)

- (void)onTLSCertValidate:(NSString*)serverHost :(NSString*)serverIP :(int*)accept;

Remarks

This event is fired during a TLS handshake. Use TLSServerChain property to access the certificate chain. In general case, components 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 component, and can be adjusted if needed.

TLSEstablished Event (FTPClient Module)

Fires when a TLS handshake with Host successfully completes.

Syntax

Swift
Objective-C

func onTLSEstablished(host: String, version: String, ciphersuite: String, connectionId: Data, abort: inout Bool)

- (void)onTLSEstablished:(NSString*)host :(NSString*)version :(NSString*)ciphersuite :(NSData*)connectionId :(int*)abort;

Remarks

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

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

TLSHandshake Event (FTPClient Module)

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

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 with TLSEstablished event. If the server chooses to request a client certificate, 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.

Remarks

This type provides access to X.509 certificate details.

Fields

bytes
Data

Returns raw certificate data in DER format.

ca
Bool

Indicates whether the certificate has a CA capability (a setting in BasicConstraints extension).

caKeyID
Data

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

Authority Key Identifier is a (non-critical) X.509 certificate extension which allows the identification of certificates produced by the same issuer, but with different public keys.

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.

Fields


bytes Data	Returns raw CRL data in DER format.
caKeyID Data	A unique identifier (fingerprint) of the CA certificate's private key, if present in the CRL.
entryCount Int32	Returns the number of certificate status entries in the CRL.
handle Int64	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());`
issuer String	The common name of the CRL issuer (CA), typically a company name.
issuerRDN String	A collection of information, in the form of [OID, Value] pairs, uniquely identifying the CRL issuer.

sigAlgorithm String	The public key algorithm that was used by the CA to sign this CRL.
tbs Data	The to-be-signed part of the CRL (the CRL without the signature part).
thisUpdate String	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.

Fields

asyncDocumentID
String

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 pre-signing (SignAsyncBegin) and completion (SignAsyncEnd) stages.

customParams
String

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

data
String

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

keyID
String

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

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

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.

ecCurves
String

Defines the elliptic curves to enable.

extensions
String

Provides access to TLS extensions.

forceResumeIfDestinationChanges
Bool

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

preSharedIdentity
String

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

preSharedKey
String

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

preSharedKeyCiphersuite
String

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

renegotiationAttackPreventionMode
RenegotiationAttackPreventionModes

Selects 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

Specifies the kind(s) of revocation check to perform.

Revocation checking is necessary to ensure the integrity of the chain and obtain up-to-date certificate validity and trustworthiness information.


crcNone (`0`)	No revocation checking
crcAuto (`1`)	Automatic mode selection. Currently this maps to crcAnyOCSPOrCRL, but it may change in the future.
crcAllCRL (`2`)	Check all provided CRL endpoints for all chain certificates.
crcAllOCSP (`3`)	Check all provided OCSP endpoints for all chain certificates.
crcAllCRLAndOCSP (`4`)	Check all CRL and OCSP endpoints for all chain certificates.
crcAnyCRL (`5`)	At least one CRL check for every certificate in the chain must succeed.
crcAnyOCSP (`6`)	At least one OCSP check for every certificate in the chain must succeed.
crcAnyCRLOrOCSP (`7`)	At least one CRL or OCSP check for every certificate in the chain must succeed. CRL endpoints are checked first.
crcAnyOCSPOrCRL (`8`)	At least one CRL or OCSP check for every certificate in the chain must succeed. OCSP endpoints are checked first.

This setting controls the way the revocation checks are performed. Typically certificates come with two types of revocation information sources: CRL (certificate revocation lists) and OCSP responders. CRLs are static objects periodically published by the CA at some online location. OCSP responders are active online services maintained by the CA that can provide up-to-date information on certificate statuses in near real time.

There are some conceptual differences between the two. CRLs are normally larger in size. Their use involves some latency because there is normally some delay between the time when a certificate was revoked and the time the subsequent CRL mentioning that is published. The benefits of CRL is that the same object can provide statuses for all certificates issued by a particular CA, and that the whole technology is much simpler than OCSP (and thus is supported by more CAs).

This setting lets you adjust the validation course by including or excluding certain types of revocation sources from the validation process. The crcAnyOCSPOrCRL setting (give preference to faster OCSP route and only demand one source to succeed) is a good choice for most of typical validation environments. The "crcAll*" modes are much stricter, and may be used in scenarios where bulletproof validity information is essential.

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

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: Case-sensitivity of file names and paths.

Whether file paths and names are 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.

CopyMode: What to do with the originals of the copied files.

Defines what to do with the originals of the files which have been copied. You can choose to just leave them, delete each original right after it has been copied, or delete files only when all of them have been transferred.

ErrorOrigin: Specifies where the error has been originated.

Specifies where the error has been originated, on the server or client side.

ErrorSeverity: Error severity.

Specifies whether a warning or an error encountered.

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.

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 component should respect the trust to CA certificates as configured in the operating system. In Windows this effectively defines whether the component 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 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: 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.

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.

Mode: What to do if the destination file already exists.

Specifies what to do if the destination file already exists. You can choose to: overwrite, append, resume, overwrite only if the destination file's size is different, save with a new name, or rename the existing destination file.

Options: Various FTP options.

Various options of FTP connection.

Recursive: Whether to scan subdirectories.

Whether the subdirectories should also be scanned for matching files.

TempPath: Path for storing temporary files.

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

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
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 automatic use of 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 chain validation module 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.

Base Config Settings

CheckKeyIntegrityBeforeUse: Enables or disable private key integrity check before use.

This global property enables or disables private key material check before each signing operation. This slows down performance a bit, but prevents a selection of attacks on RSA keys where keys with unknown origins are used.

You can switch this property off to improve performance if your project only uses known, good private keys.

CookieCaching: Specifies whether a cookie cache should be used for HTTP(S) transports.

Set this property to enable or disable cookies caching for the class.

Supported values are:


off		No caching (default)
local		Local caching (supported for HTTPClient, RESTClient and SOAPClient only)

Use this property to get cookies from the internal cookie storage of the class and/or restore them back between application sessions.

DefDeriveKeyIterations: Specifies the default key derivation algorithm iteration count.

This global property sets the default number of iterations for all supported key derivation algorithms. Note that you can provide the required number of iterations by using properties of the relevant key generation component; this global setting is used in scenarios where specific iteration count is not or cannot be provided.

EnableClientSideSSLFFDHE: Enables or disables finite field DHE key exchange support in TLS clients.

This global property enables or disables support for finite field DHE key exchange methods in TLS clients. FF DHE is a slower algorithm if compared to EC DHE; enabling it may result in slower connections.

This setting only applies to sessions negotiated with TLS version 1.3.

GlobalCookies: Gets or sets global cookies for all the HTTP transports.

Use this property to get cookies from the GLOBAL cookie storage or restore them back between application sessions. These cookies will be used by all the classes that have its CookieCaching property set to "global".

HttpUserAgent: Specifies the user agent name to be used by all HTTP clients.

This global setting defines the User-Agent field of the HTTP request provides information about the software that initiates the request. This value will be used by all the HTTP clients including the ones used internally in other classes.

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


none		No flush (caching only)
immediate		Immediate flush (real-time logging)
maxcount		Flush cached entries upon reaching LogMaxEventCount entries in the cache.

LogLevel: Specifies the debug log level.

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.

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.

Tag: Allows to store any custom data.

Use this config property to store any custom data.

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.

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.
