# ExternalCryptoKeyID Property ([RESTClient](#restclient-component) Component)

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

## Syntax

*Go Syntax*

```text
func (obj *RESTClient) ExternalCryptoKeyID() (string, error)func (obj *RESTClient) SetExternalCryptoKeyID(value string) error
```

## 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 [ExternalCryptoKeySecret](#externalcryptokeysecret-property-restclient-component) 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:

```text
  signer.ExternalCrypto.KeyID = "MainSigningKey";
  signer.ExternalCrypto.KeySecret = "abcdef0123456789";
```

## Data Type

**string**

# ExternalCryptoKeySecret Property ([RESTClient](#restclient-component) Component)

The pre-shared key used for DC request authentication.

## Syntax

*Go Syntax*

```text
func (obj *RESTClient) ExternalCryptoKeySecret() (string, error)func (obj *RESTClient) SetExternalCryptoKeySecret(value string) error
```

## Default Value

""

## Remarks

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.

## 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. |

| 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.

*Go Syntax*

```text
func (obj *RESTClient) TrustedCertCount() (int32, error)func (obj *RESTClient) SetTrustedCertCount(value int32) error
```

## Default Value

0

## Remarks

This property controls the size of the following arrays:

- [TrustedCertBytes](#trustedcertbytes-property-restclient-component)
- [TrustedCertHandle](#trustedcerthandle-property-restclient-component)

The array indices start at *0* and end at *TrustedCertCount - 1*.

## Data Type

**int32**

# TrustedCertBytes Property ([RESTClient](#restclient-component) Component)

Returns the raw certificate data in DER format.

## Syntax

*Go Syntax*

```text
func (obj *RESTClient) TrustedCertBytes(TrustedCertIndex int32) ([]byte, error)
```

## Remarks

Returns the raw certificate data in DER format.

The *TrustedCertIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [TrustedCertCount](#trustedcertcount-property-restclient-component) property.

This property is read-only.

## Data Type

**[]byte**

# TrustedCertHandle Property ([RESTClient](#restclient-component) Component)

Allows to get or set a 'handle', a unique identifier of the underlying property object.

## Syntax

*Go Syntax*

```

## Default Value

0

## Remarks

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.

```text
  pdfSigner.setSigningCertHandle(certMgr.getCertHandle());
```

The *TrustedCertIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [TrustedCertCount](#trustedcertcount-property-restclient-component) property.

## Data Type

**int64**

# Config Method ([RESTClient](#restclient-component) Component)

Sets or retrieves a configuration setting.

## Syntax

*Go Syntax*

```text
func (obj *RESTClient) Config(ConfigurationString string) (string, error)
```

## Remarks

Config is a generic method available in every struct. It is used to set and retrieve [configuration settings](#config-settings-restclient-component) for the struct.

These 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.

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](#config-settings-restclient-component), you must call *Config("PROPERTY")*. The value will be returned as a string.

# Delete Method ([RESTClient](#restclient-component) Component)

Sends a DELETE request to the server.

## Syntax

*Go Syntax*

```text
func (obj *RESTClient) Delete(Url string) error
```

## Remarks

Use this method to send a DELETE request to server. In response to this request, the server may (without any guarantees) delete the resource specified in *Url*. Most of the servers disable DELETE requests.

If this request fails, an exception will be thrown, and the error details published in [StatusCode](#statuscode-property-restclient-component) and [ReasonPhrase](#reasonphrase-property-restclient-component) properties.

Note that any parameters you intend to pass to this method should be properly encoded before this method is called.

# DoAction Method ([RESTClient](#restclient-component) Component)

Performs an additional action.

## Syntax

*Go Syntax*

```text
func (obj *RESTClient) DoAction(ActionID string, ActionParams string) (string, error)
```

## Remarks

DoAction is a generic method available in every struct. 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;...*.

Common ActionIDs:

|  |  |  |  |
| --- | --- | --- | --- |
| Action | Parameters | Returned value | Description |
| ResetTrustedListCache | none | none | Clears the cached list of trusted lists. |
| ResetCertificateCache | none | none | Clears the cached certificates. |
| ResetCRLCache | none | none | Clears the cached CRLs. |
| ResetOCSPResponseCache | none | none | Clears the cached OCSP responses. |

# Get Method ([RESTClient](#restclient-component) Component)

Sends a GET request to the server.

## Syntax

*Go Syntax*

```text
func (obj *RESTClient) Get(Url string) error
```

## Remarks

GET is one of the most widely used HTTP requests. The server responds with the content of the resource specified in *Url*.

If the request is successful, the received content will be available in [OutputBytes](#outputbytes-property-restclient-component) and [OutputString](#outputstring-property-restclient-component) properties. Otherwise an exception will be thrown, and the error details published in [StatusCode](#statuscode-property-restclient-component) and [ReasonPhrase](#reasonphrase-property-restclient-component) properties.

Note that any parameters you intend to pass to this method should be properly encoded before this method is called.

# Head Method ([RESTClient](#restclient-component) Component)

Sends a HEAD request to the server.

## Syntax

*Go Syntax*

```text
func (obj *RESTClient) Head(Url string) error
```

## Remarks

HEAD is very similar to GET, with the only difference being that only the headers (but not the content) is returned.

HEAD is often use to retrieve the parameters of the resource, such as its size and modification date. If the request is successful, those details will be available via ResponseParameters and ResponseHeaders properties. Otherwise, an exception will be thrown, and the error details published in [StatusCode](#statuscode-property-restclient-component) and [ReasonPhrase](#reasonphrase-property-restclient-component) properties.

Note that any parameters you intend to pass to this method should be properly encoded before this method is called.

# ExternalSign Event ([RESTClient](#restclient-component) Component)

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

## Syntax

*Go Syntax*

```text
// RESTClientExternalSignEventArgs carries the RESTClient ExternalSign event's parameters.
type RESTClientExternalSignEventArgs struct {...}

func (args *RESTClientExternalSignEventArgs) OperationId() string
func (args *RESTClientExternalSignEventArgs) HashAlgorithm() string
func (args *RESTClientExternalSignEventArgs) Pars() string
func (args *RESTClientExternalSignEventArgs) Data() string
func (args *RESTClientExternalSignEventArgs) SignedData() string
func (args *RESTClientExternalSignEventArgs) SetSignedData(value string)

// RESTClientExternalSignEvent defines the signature of the RESTClient ExternalSign event's handler function.
type RESTClientExternalSignEvent func(sender *RESTClient, args *RESTClientExternalSignEventArgs)

func (obj *RESTClient) GetOnExternalSignHandler() RESTClientExternalSignEvent
func (obj *RESTClient) SetOnExternalSignHandler(handlerFunc RESTClientExternalSignEvent)
```

## 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:

```text
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();
};
```

type RESTClientNotificationEvent func(sender *RESTClient, args *RESTClientNotificationEventArgs)

func (obj *RESTClient) GetOnNotificationHandler() RESTClientNotificationEvent
func (obj *RESTClient) SetOnNotificationHandler(handlerFunc RESTClientNotificationEvent)
```

## Remarks

The struct fires this event to let the application know about some event, occurrence, or milestone in the struct. 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 the *EventID* parameter. *EventParam* contains any parameters accompanying the occurrence. Depending on the type of the struct, the exact action it is performing, or the document being processed, one or both may be omitted.

# Progress Event ([RESTClient](#restclient-component) Component)

Fires periodically during the data transfer.

## Syntax

*Go Syntax*

```text
// RESTClientProgressEventArgs carries the RESTClient Progress event's parameters.
type RESTClientProgressEventArgs struct {...}

func (args *RESTClientProgressEventArgs) Total() int64
func (args *RESTClientProgressEventArgs) Current() int64
func (args *RESTClientProgressEventArgs) Cancel() bool
func (args *RESTClientProgressEventArgs) SetCancel(value bool)

// RESTClientProgressEvent defines the signature of the RESTClient Progress event's handler function.
type RESTClientProgressEvent func(sender *RESTClient, args *RESTClientProgressEventArgs)

func (obj *RESTClient) GetOnProgressHandler() RESTClientProgressEvent
func (obj *RESTClient) SetOnProgressHandler(handlerFunc RESTClientProgressEvent)
```

## Remarks

Use this event to check the progress of an upload or download operation. *Total* indicates the total number of bytes to be transferred; *Current* specifies how much data has been transferred so far, and *Cancel* gives you a chance to cancel the operation.

# Redirection Event ([RESTClient](#restclient-component) Component)

Fires when the server suggests a redirect.

## Syntax

*Go Syntax*

```text
// RESTClientRedirectionEventArgs carries the RESTClient Redirection event's parameters.
type RESTClientRedirectionEventArgs struct {...}

func (args *RESTClientRedirectionEventArgs) OldURL() string
func (args *RESTClientRedirectionEventArgs) NewURL() string
func (args *RESTClientRedirectionEventArgs) SetNewURL(value string)

func (args *RESTClientRedirectionEventArgs) AllowRedirection() bool
func (args *RESTClientRedirectionEventArgs) SetAllowRedirection(value bool)

// RESTClientRedirectionEvent defines the signature of the RESTClient Redirection event's handler function.
type RESTClientRedirectionEvent func(sender *RESTClient, args *RESTClientRedirectionEventArgs)

func (obj *RESTClient) GetOnRedirectionHandler() RESTClientRedirectionEvent
func (obj *RESTClient) SetOnRedirectionHandler(handlerFunc RESTClientRedirectionEvent)
```

## Remarks

This event is fired when the server suggests a redirection request (typically via a 301 or 302 response). *OldURL* indicates the 'from' page, and *NewURL* indicates the 'to' one. The destination page can be altered by the application if needed. Use *AllowRedirection* to block undesirable redirects.

Generally, this is a notification event: the component handles redirections automatically. Use the *MaxRedirections* config property to limit the number of redirection hops.

# ServerEvent Event ([RESTClient](#restclient-component) Component)

Fires when a server-sent event is received.

## Syntax

*Go Syntax*

```text
// RESTClientServerEventEventArgs carries the RESTClient ServerEvent event's parameters.
type RESTClientServerEventEventArgs struct {...}

func (args *RESTClientServerEventEventArgs) Evt() string
func (args *RESTClientServerEventEventArgs) Data() string
func (args *RESTClientServerEventEventArgs) Id() string
// RESTClientServerEventEvent defines the signature of the RESTClient ServerEvent event's handler function.
type RESTClientServerEventEvent func(sender *RESTClient, args *RESTClientServerEventEventArgs)

func (obj *RESTClient) GetOnServerEventHandler() RESTClientServerEventEvent
func (obj *RESTClient) SetOnServerEventHandler(handlerFunc RESTClientServerEventEvent)
```

## Remarks

Use this event to capture server-sent events (SSE). This event is only fired when the component is used in the SSE subscriber mode.

Use the Subscribe method to subscribe to an endpoint that sends SSEs.

# TLSCertNeeded Event ([RESTClient](#restclient-component) Component)

Fires when a remote TLS party requests a client certificate.

## Syntax

*Go Syntax*

```text
// RESTClientTLSCertNeededEventArgs carries the RESTClient TLSCertNeeded event's parameters.
type RESTClientTLSCertNeededEventArgs struct {...}

func (args *RESTClientTLSCertNeededEventArgs) Host() string
func (args *RESTClientTLSCertNeededEventArgs) CANames() string
// RESTClientTLSCertNeededEvent defines the signature of the RESTClient TLSCertNeeded event's handler function.
type RESTClientTLSCertNeededEvent func(sender *RESTClient, args *RESTClientTLSCertNeededEventArgs)

func (obj *RESTClient) GetOnTLSCertNeededHandler() RESTClientTLSCertNeededEvent
func (obj *RESTClient) SetOnTLSCertNeededHandler(handlerFunc RESTClientTLSCertNeededEvent)
```

## 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](#tlshandshake-event-restclient-component) event for the given host and, if the certificate was accepted, succeeded by the [TLSEstablished](#tlsestablished-event-restclient-component) event.

# TLSCertValidate Event ([RESTClient](#restclient-component) Component)

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

## Syntax

*Go Syntax*

```text
// RESTClientTLSCertValidateEventArgs carries the RESTClient TLSCertValidate event's parameters.
type RESTClientTLSCertValidateEventArgs struct {...}

func (args *RESTClientTLSCertValidateEventArgs) ServerHost() string
func (args *RESTClientTLSCertValidateEventArgs) ServerIP() string
func (args *RESTClientTLSCertValidateEventArgs) Accept() bool
func (args *RESTClientTLSCertValidateEventArgs) SetAccept(value bool)

// RESTClientTLSCertValidateEvent defines the signature of the RESTClient TLSCertValidate event's handler function.
type RESTClientTLSCertValidateEvent func(sender *RESTClient, args *RESTClientTLSCertValidateEventArgs)

func (obj *RESTClient) GetOnTLSCertValidateHandler() RESTClientTLSCertValidateEvent
func (obj *RESTClient) SetOnTLSCertValidateHandler(handlerFunc RESTClientTLSCertValidateEvent)
```

## Remarks

This event is fired during a TLS handshake. Use the TLSServerChain 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.

# TLSEstablished Event ([RESTClient](#restclient-component) Component)

Fires when a TLS handshake with Host successfully completes.

## Syntax

*Go Syntax*

```text
// RESTClientTLSEstablishedEventArgs carries the RESTClient TLSEstablished event's parameters.
type RESTClientTLSEstablishedEventArgs struct {...}

func (args *RESTClientTLSEstablishedEventArgs) Host() string
func (args *RESTClientTLSEstablishedEventArgs) Version() string
func (args *RESTClientTLSEstablishedEventArgs) Ciphersuite() string
func (args *RESTClientTLSEstablishedEventArgs) ConnectionId() []byte
func (args *RESTClientTLSEstablishedEventArgs) Abort() bool
func (args *RESTClientTLSEstablishedEventArgs) SetAbort(value bool)

// RESTClientTLSEstablishedEvent defines the signature of the RESTClient TLSEstablished event's handler function.
type RESTClientTLSEstablishedEvent func(sender *RESTClient, args *RESTClientTLSEstablishedEventArgs)

func (obj *RESTClient) GetOnTLSEstablishedHandler() RESTClientTLSEstablishedEvent
func (obj *RESTClient) SetOnTLSEstablishedHandler(handlerFunc RESTClientTLSEstablishedEvent)
```

## 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.

# TLSHandshake Event ([RESTClient](#restclient-component) Component)

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

## Syntax

*Go Syntax*

```text
// RESTClientTLSHandshakeEventArgs carries the RESTClient TLSHandshake event's parameters.
type RESTClientTLSHandshakeEventArgs struct {...}

func (args *RESTClientTLSHandshakeEventArgs) Host() string
func (args *RESTClientTLSHandshakeEventArgs) Abort() bool
func (args *RESTClientTLSHandshakeEventArgs) SetAbort(value bool)

// RESTClientTLSHandshakeEvent defines the signature of the RESTClient TLSHandshake event's handler function.
type RESTClientTLSHandshakeEvent func(sender *RESTClient, args *RESTClientTLSHandshakeEventArgs)

func (obj *RESTClient) GetOnTLSHandshakeHandler() RESTClientTLSHandshakeEvent
func (obj *RESTClient) SetOnTLSHandshakeHandler(handlerFunc RESTClientTLSHandshakeEvent)
```

## 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 [TLSEstablished](#tlsestablished-event-restclient-component) event. If the server chooses to request a client certificate, the [TLSCertNeeded](#tlscertneeded-event-restclient-component) event will also be fired.

# TLSPSK Event ([RESTClient](#restclient-component) Component)

Notifies the application about the PSK key exchange.

## Syntax

*Go Syntax*

```text
// RESTClientTLSPSKEventArgs carries the RESTClient TLSPSK event's parameters.
type RESTClientTLSPSKEventArgs struct {...}

func (args *RESTClientTLSPSKEventArgs) Host() string
func (args *RESTClientTLSPSKEventArgs) Hint() string
// RESTClientTLSPSKEvent defines the signature of the RESTClient TLSPSK event's handler function.
type RESTClientTLSPSKEvent func(sender *RESTClient, args *RESTClientTLSPSKEventArgs)

func (obj *RESTClient) GetOnTLSPSKHandler() RESTClientTLSPSKEvent
func (obj *RESTClient) SetOnTLSPSKHandler(handlerFunc RESTClientTLSPSKEvent)
```

## 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 TLSSettings to provide the pre-shared key to the component.

# TLSShutdown Event ([RESTClient](#restclient-component) Component)

Reports the graceful closure of a TLS connection.

## Syntax

*Go Syntax*

```text
// RESTClientTLSShutdownEventArgs carries the RESTClient TLSShutdown event's parameters.
type RESTClientTLSShutdownEventArgs struct {...}

func (args *RESTClientTLSShutdownEventArgs) Host() string
// RESTClientTLSShutdownEvent defines the signature of the RESTClient TLSShutdown event's handler function.
type RESTClientTLSShutdownEvent func(sender *RESTClient, args *RESTClientTLSShutdownEventArgs)

func (obj *RESTClient) GetOnTLSShutdownHandler() RESTClientTLSShutdownEvent
func (obj *RESTClient) SetOnTLSShutdownHandler(handlerFunc RESTClientTLSShutdownEvent)
```

## 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 ([RESTClient](#restclient-component) Component)

 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](#config-method-restclient-component) method.

### RESTClient Config Settings

**AuthStickToLastURL**: TBD.TBD

**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](#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](#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](#RevocationCacheAgePolicy) for configuring this setting together with the related cached revocation freshness settings.

This setting is evaluated independently from [CachedCRLMaxAge](#CachedCRLMaxAge) and [CachedCRLMaxAgeRatio](#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](#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](#CachedOCSPResponseMaxAge) to limit their age. See [RevocationCacheAgePolicy](#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](#RevocationCacheAgePolicy) for configuring this setting together with the related cached revocation freshness settings.

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

**CacheStreamOutput**: Tells the component whether to cache stream- and file-bound responses in the component.Set this property to true to enable caching of potentially long responses obtained with Get method. If the response is cached, it will be available via OutputBytes and OutputString properties after the request is completed, but may occupy extra memory resources.

**Cookies**: TBD.TBD

**DefClientCookieFmt**: TBD.TBD

**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.

**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.

**ForceNTLMAuth**: Activates and enforces NTLM authentication.Set this property to True to force NTLM (Windows Integrated) authentication.

**IgnoreCookieSecureFlag**: TBD.TBD

**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](#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.

**IgnoreUnknownTransferEncodings**: All incoming responses with unknown transfer encodings are ignored if this property is true.All incoming responses with unknown transfer encodings are ignored if this property is true.

**KeepConnectionOpen**: TBD.TBD

**MaxRedirections**: The maximum number of HTTP redirects.Specifies the maximum number of HTTP redirects. Value 0 prevents any redirections, and -1 allows unlimited redirections.

**OutputFile**: Specifies the file where the received content should be saved to.This is a backward-compatibility duplicate of the *OutputFile* property. Use *OutputFile* instead.

**PersistentAuthHeader**: Whether to resend NTLM negotiation on every request.Specifies whether to resend NTLM negotiation on every request.

**RequestCompressionGZip**: Ask server to enforce GZip compression.Ask the server to use GZip compression instead of Deflate. This setting only makes sense when UseCompression is set to true. Most modern servers support both Deflate and GZip, so primary use case for this setting is the need to communicate to an older server.

**RequestCompressionLevel**: Ask server to use the specified compression level.Ask server to use the specified compression level.

**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](#CachedCRLOverlapTime), [CachedOCSPResponseOverlapTime](#CachedOCSPResponseOverlapTime), [CachedCRLMaxAge](#CachedCRLMaxAge), [CachedOCSPResponseMaxAge](#CachedOCSPResponseMaxAge), [CachedCRLMaxAgeRatio](#CachedCRLMaxAgeRatio), and [CachedOCSPResponseMaxAgeRatio](#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](#CachedCRLOverlapTime), [CachedOCSPResponseOverlapTime](#CachedOCSPResponseOverlapTime), [CachedCRLMaxAge](#CachedCRLMaxAge), [CachedOCSPResponseMaxAge](#CachedOCSPResponseMaxAge), [CachedCRLMaxAgeRatio](#CachedCRLMaxAgeRatio), and [CachedOCSPResponseMaxAgeRatio](#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.

**SendBufferSize**: Size of send buffer in bytes.The size of blocks used to send data to the server.

**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.

**SuppressRedirectionContent**: Whether to suppress the redirection content.If this property is set to True, the redirection content will be silently suppressed by the struct. Otherwise the message containing a redirection code will be processed as usual, the [Redirection](#redirection-event-restclient-component) event will be fired, and the data will be written to [OutputString](#outputstring-property-restclient-component) or [OutputBytes](#outputbytes-property-restclient-component).

**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](PDFSigner.md#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.

**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
- 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

**Use100Continue**: Whether to use 100-continue for POST and PUT commands.Set this property to True to use the 100-continue approach for POST and PUT commands. In this approach, prior to sending the request body, the client sends a request message asking the server whether it is willing to accept the request body. The request body is sent only if the server accepts it.

**UseCompression**: Enables compression capability.Use this property to tell the server that it can compress the response data if it wants to. Deflate mechanism is requested by default; use RequestCompressionGZip to change that to GZip.

**UseEnvStorages**: Enables or disables use of the environment storages.Enable this property to make the chain validation module automatically look up missing CA and intermediate certificates in the environment storages.

**UseKerberosAuth**: TBD.TBD

**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.

**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.

### Base Config Settings

**ASN1UseGlobalTagCache**: Controls whether ASN.1 module should use a global object cache.This is a performance setting. It is unlikely that you will ever need to adjust it.

**AssignSystemSmartCardPins**: Specifies whether CSP-level PINs should be assigned to CNG keys.This is a low-level tweak for certain cryptographic providers. It is unlikely that you will ever need to adjust it.

**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 struct.

Supported values are:

|  |  |  |
| --- | --- | --- |
| off |  | No caching (default) |
| local |  | Local caching |
| global |  | Global caching |

**Cookies**: Gets or sets local cookies for the struct.Use this property to get cookies from the internal cookie storage of the struct 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.

**DNSLocalSuffix**: The suffix to assign for TLD names.Use this global setting to adjust the default suffix to assign to top-level domain names. The default is *.local*.

**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.

**EnableSSHMLKEM**: Enables support for ML-KEM/hybrid key exchange algorithms in SSH client and server components.Use this setting to enable hybrid key exchange algorithms in client and server SSH and SFTP components. This is a global setting that enables ML-KEM blanketly in all SSH-dependent components.

**EnableTLSMLKEM**: Enables support for ML-KEM and hybrid groups in TLS client and server components.Use this setting to enable ML-KEM and hybrid key exchange groups in client and server TLS components. This is a global setting that enables ML-KEM blanketly in all TLS-dependent components.

**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 structs that have its *CookieCaching* property set to "global".

**HardwareCryptoUsePolicy**: The hardware crypto usage policy.This global setting controls the hardware cryptography usage policy.

Supported Values:

|  |  |
| --- | --- |
| auto | Use hardware cryptography if available; otherwise, fall back to software-based cryptography (default). |
| enable | Always attempt to use hardware cryptography. If unavailable, exception will be thrown. |
| disable | Do not use hardware cryptography. |

**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 structs.

**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.

**LogDestination**: Specifies the debug log destination.Contains a comma-separated list of values that specifies where debug log should be dumped.

Supported values are:

|  |  |  |
| --- | --- | --- |
| file |  | File |
| console |  | Console |

**LogFilters**: Specifies the debug log filters.Contains a comma-separated list of value pairs ("name:value") that describe filters.

Supported filter names are:

|  |  |  |
| --- | --- | --- |
| exclude-package |  | Exclude a package specified in the value |
| exclude-module |  | Exclude a module specified in the value |
| exclude-class |  | Exclude a class specified in the value |
| exclude-method |  | Exclude a method specified in the value |
| include-package |  | Include a package specified in the value |
| include-module |  | Include a module specified in the value |
| include-class |  | Include a class specified in the value |

| 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.

|  |  |  |
| --- | --- | --- |
| none |  | No rotation |
| deleteolder |  | Delete older entries from the cache upon reaching LogMaxEventCount |

**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.

**PKICache**: Specifies which PKI elements (certificates, CRLs, OCSP responses) should be cached.The PKICache setting specifies which Public Key Infrastructure (PKI) elements should be cached to optimize performance and reduce retrieval times. It supports comma-separated values to indicate the specific types of PKI data that should be cached.

Supported Values:

|  |  |
| --- | --- |
| certificate | Enables caching of certificates. |
| crl | Enables caching of Certificate Revocation Lists (CRLs). |
| ocsp | Enables caching of OCSP (Online Certificate Status Protocol) responses. |

Example (default value):

```text
PKICache=certificate,crl,ocsp
```

 In this example, the component caches certificates, CRLs, and OCSP responses.

**PKICachePath**: Specifies the file system path where cached PKI data is stored.The PKICachePath setting defines the file system path where cached PKI data (e.g., certificates, CRLs, OCSP responses and Trusted Lists) will be stored. This allows the system to persistently save and retrieve PKI cache data, even across application restarts.

The default value is an empty string - no cached PKI data is stored on disk.

Example:

```text
PKICachePath=C:\Temp\cache
```

 In this example, the cached PKI data is stored in the C:\Temp\cache directory.

**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.

**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.

**Tag**: Allows to store any custom data.Use this config property to store any custom data.

**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).

**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.

**UseSystemNativeSizeCalculation**: An internal CryptoAPI access tweak.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.

Syntax:

```text
Config("XMLRDNDescriptorName[OID]=PrimaryName,Alias1,Alias2");
```

Where:

OID: The Object Identifier from the certificate's IssuerRDN or SubjectRDN that you want to map.

PrimaryName: The main descriptor name used in the XML signature when the OID is encountered.

Alias1, Alias2, ...: Optional alternative names recognized during parsing.

Usage Examples:

Map OID 2.5.4.5 to SERIALNUMBER:

```text
Config("XMLRDNDescriptorName[2.5.4.5]=SERIALNUMBER");
```

Map OID 1.2.840.113549.1.9.1 to E, with aliases EMAIL and EMAILADDRESS:

```text
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).

**XMLRDNDescriptorSeparator**: Specifies the separator used between descriptors in RDN.Specifies the separator used between descriptors in the ds:IssuerRDN and ds:SubjectRDN elements during XML signing. By default, this property is set to ", " value.
