Properties Methods Events Config Settings Errors

The PDFVerifier module verifies signatures over PDF documents.

Syntax

SecureBlackbox.PDFVerifier

Remarks

Use PDFVerifier to validate electronic signatures over PDF documents. Generic and PAdES signatures are supported. PDFVerifier verifier = new PDFVerifier(); // Set the signed PDF document that you want to verify verifier.setInputFile("signed.pdf"); verifier.verify(); // Verification information for (int idx = 0; idx < verifier.getSignatures().size(); idx++) { System.out.println("Signature " + (idx + 1)); System.out.println(" Timestamp: " + verifier.getSignatures().item(idx).getValidatedSigningTime()); System.out.print(" Validation Result: " + verifier.getSignatures().item(idx).getSignatureValidationResult() + ", "); switch (verifier.getSignatures().item(idx).getSignatureValidationResult()) { case svtValid: System.out.println("The signature is valid."); break; case svtUnknown: System.out.println("Signature validity is unknown."); break; case svtCorrupted: System.out.println("The signature is corrupted."); break; case svtSignerNotFound: System.out.println("Failed to acquire the signing certificate. The signature cannot be validated."); break; case svtFailure: System.out.println("General failure."); break; default: System.out.println("Signature validity is unknown."); break; } }

PDFVerifier validates each signature from two perspectives: the integrity and validity of the signature itself (i.e. its correspondence to the document data it covers), and the validity and trustworthiness of the signing certificate chain. These two signature aspects are generally independent of each other: the signature may be valid but the chain may not be trusted, or the other way around, the chain may be trusted but the integrity of the signature may be violated. Under normal circumstances both the signature and the chain must be valid for the signature to be considered good.

To initiate the validation, assign the path to the signed PDF file to the InputFile property (alternatively, you can provide it in a memory buffer via the InputBytes property), and call the Verify method. For every signature located in the document, PDFVerifier will fire the SignatureFound event. This event lets you specify whether you want PDFVerifier to validate the signature, the chain, or both.

Note: it does not mean that any of the two is optional. This API lets you be flexible in how you validate documents in your code in accordance with the specifics of your application and its usage scenarios. For example, if your trust environment relies on certificate pinning, validating the chain by PDFVerifier internally may cause unnecessary burden on the system, in which case it may be reasonable to disable it in the event handler.

Once SignatureFound returns, PDFVerifier proceeds to the signature validation routine in accordance with the provided settings. Upon completion of the validation, the SignatureValidated event is fired, and the validation results are separately provided via the and fields of the associated signature object. Other information about the signature can be accessed via the Signatures property.

The PDF format uses incremental updates to introduce changes to the document. This implies that a signature may cover not the whole document, but rather a certain revision of it. Strictly speaking, every signature in a PDF document, apart from perhaps the last one, covers just some part of the document. In most cases that part matches the revision of the document that existed before all the subsequent signatures had been added.

Because of these specifics of the PDF format, it is crucially important to understand which part of the document is covered by a specific signature. Use the field to establish the scope of a signature. The revision of the document covered by that specific signature ranges from byte 0 to CoverageEndsAt. Alternatively, you can use the GetSignedVersion method to extract the signed revision to a file.

Useful settings and properties

The following properties of PDFVerifier may be handy when working with this class:

OfflineMode lets you validate the document without contacting online revocation sources. Paired with switched-off system trust settings, it can be used to establish the long-term validity of the document and the completeness of the validation material included in it.
RevocationCheck lets you adjust the revocation checking preferences.
returns the signing time as recorded in the embedded signature timestamp. This is in contrast to , which returns the signing time as specified by the signer.
is a great way to find out the details of chain validation failures. This property returns a comprehensive validation log that reports all the issues encountered during the validation.
If the document is encrypted (in addition to being signed), the Encrypted event will fire, asking you for the decryption certificate or password.

By default, PDFVerifier uses the system trust settings to establish certificate chain validity. You can configure it to use your own, custom validation environment by providing the necessary trust elements via KnownCertificates, TrustedCertificates, KnownCRLs, and other similar properties.

Use this property to supply a list of additional certificates that might be needed for chain validation. 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.

KnownCRLs Property (PDFVerifier Module)

Additional CRLs for chain validation.

Syntax

Swift
Objective-C

- (long long)knownCRLHandle:(int)knownCRLIndex;
- (void)setKnownCRLHandle:(int)knownCRLIndex :(long long)newKnownCRLHandle;

Default Value

Remarks

Use this property to supply additional CRLs that might be needed for chain validation. This property may be helpful when a chain is validated in offline mode, and the associated CRLs are stored separately from the signed message or document.

KnownOCSPs Property (PDFVerifier Module)

Additional OCSP responses for chain validation.

Syntax

Swift
Objective-C

public var knownOCSPs: Array<OCSPResponse> {
  get {...}
}


@property (nonatomic,readwrite,assign,getter=knownOCSPCount,setter=setKnownOCSPCount:) int knownOCSPCount;

  get {...}
  set {...}
}


@property (nonatomic,readwrite,assign,getter=offlineMode,setter=setOfflineMode:) BOOL offlineMode;

- (BOOL)offlineMode;
- (void)setOfflineMode :(BOOL)newOfflineMode;

Default Value

False

Remarks

When working in offline mode, the class restricts itself from using any online revocation information sources, such as CRL or OCSP responders.

Offline mode may be useful if there is a need to verify the completeness of the validation information included within the signature or provided via KnownCertificates, KnownCRLs, and other related properties.

- (NSString*)profile;
- (void)setProfile :(NSString*)newProfile;

Default Value

Remarks

Advanced signatures come in many variants, which are often defined by parties that needs to process them or by local standards. SecureBlackbox profiles are sets of pre-defined configurations which correspond to particular signature variants. By specifying a profile, you are pre-configuring the component to make it produce the signature that matches the configuration corresponding to that profile.

  case crcAnyCRLOrOCSP = 7
  case crcAnyOCSPOrCRL = 8
}


@property (nonatomic,readwrite,assign,getter=revocationCheck,setter=setRevocationCheck:) int revocationCheck;

- (int)revocationCheck;
- (void)setRevocationCheck :(int)newRevocationCheck;

Default Value

Remarks

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

Certificate Revocation Lists (CRLs) and Online Certificate Status Protocol (OCSP) responses serve the same purpose of ensuring that the certificate had not been revoked by the Certificate Authority (CA) at the time of use. Depending on your circumstances and security policy requirements, you may want to use either one or both of the revocation information source types.


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.

TrustedCertificates Property (PDFVerifier Module)

A list of trusted certificates for chain validation.

Syntax

Swift
Objective-C

public var trustedCertificates: Array<Certificate> {
  get {...}
}


@property (nonatomic,readwrite,assign,getter=trustedCertCount,setter=setTrustedCertCount:) int trustedCertCount;

- (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.

ValidationMoment Property (PDFVerifier Module)

The time point at which signature validity is to be established.

Syntax

Swift
Objective-C

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


@property (nonatomic,readwrite,assign,getter=validationMoment,setter=setValidationMoment:) NSString* validationMoment;

- (NSString*)validationMoment;
- (void)setValidationMoment :(NSString*)newValidationMoment;

Default Value

Remarks

Use this property to specify the moment in time at which signature validity should be established. The time is in UTC. Leave the setting empty to stick to the default moment (either the signature creation time or the current time).

The validity of the same signature may differ depending on the time point chosen due to temporal changes in chain validities, revocation statuses, and timestamp times.

Close Method (PDFVerifier Module)

Closes an opened document.

Syntax

Swift
Objective-C

public func close(saveChanges: Bool) throws -> Void

- (void)close:(BOOL)saveChanges;

Remarks

Use this method to close a previously opened document. The SaveChanges parameter is only taken into account if the document was opened in edit mode.

Config Method (PDFVerifier 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.

DoAction Method (PDFVerifier Module)

Performs an additional action.

Syntax

Swift
Objective-C

public func doAction(actionID: String, actionParams: String) throws -> String

- (NSString*)doAction:(NSString*)actionID :(NSString*)actionParams;

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;....

GetAttachedBytes Method (PDFVerifier Module)

Saves a PDF attachment to a byte array.

Syntax

Swift
Objective-C

public func getAttachedBytes(index: Int32) throws -> Data

- (NSData*)getAttachedBytes:(int)index;

Remarks

Use this method to retrieve the contents of an attached file as a byte array.

GetAttachedFile Method (PDFVerifier Module)

Saves a PDF attachment to a file.

Syntax

Swift
Objective-C

public func getAttachedFile(index: Int32, path: String) throws -> Void

- (void)getAttachedFile:(int)index :(NSString*)path;

Remarks

Use this method to retrieve the contents of an attached file and save it to a file.

GetSignedVersion Method (PDFVerifier Module)

Returns the part of the document that is covered by the signature.

Syntax

Swift
Objective-C

public func getSignedVersion(sigLabel: String) throws -> Void

- (void)getSignedVersion:(NSString*)sigLabel;

Remarks

Use this method to retrieve the revision of the document that is covered by the SigLabel signature.

PDF documents often use the incremental updates approach, with any changes being appended to the document without altering the existing revision. This may lead to situations where a signature only covers a part of the document (one of the past revisions), but not the subsequent changes. This method provides means to extract the revision that is actually certified by the signature.

It is recommended that you use this method when validating signatures to make sure the signature covers what you expect it to cover.

An alternative to this method is to check the field of the signature object and match it to the document length.

Open Method (PDFVerifier Module)

Opens a document for verifying or removing signatures.

Syntax

Swift
Objective-C

public func open(editMode: Bool) throws -> Void

- (void)open:(BOOL)editMode;

Remarks

Use this method to open a document for verifying or removing signatures, or for extracting signed content. When finished, call Close to complete the operation and release any allocated resources.

Set EditMode to true to open the document in edit mode (only useful if you intend to remove signatures).

Reset Method (PDFVerifier Module)

Resets the component settings.

Syntax

Swift
Objective-C

public func reset() throws -> Void

- (void)reset;

Remarks

Reset is a generic method available in every class.

Revalidate Method (PDFVerifier Module)

Revalidates a signature in accordance with current settings.

Syntax

Swift
Objective-C

public func revalidate(sigLabel: String) throws -> Void

- (void)revalidate:(NSString*)sigLabel;

Remarks

Use this method to revalidate a signature in the opened PDF document.

SelectInfo Method (PDFVerifier Module)

Select signature information for a specific entity.

Syntax

Swift
Objective-C

public func selectInfo(entityLabel: String, infoType: Int32, clearSelection: Bool) throws -> Void

- (void)selectInfo:(NSString*)entityLabel :(int)infoType :(BOOL)clearSelection;

Remarks

Use this method to select (or filter) signature-related information for a specific signature element.

Provide the unique label of the entity that you are interested in via the EntityLabel parameter. Use one of the following filters, or their combination, to specify what information you are interested in:


sitEntity	`1`	Select the current entity
sitParentEntity	`2`	Select the parent entity of the current entity
sitTimestamps	`4`	Select all timestamps covering the current entity
sitSignatures	`8`	Select all signatures covering the current entity
sitSigningChain	`16`	Select the signing chain of the current entity
sitEmbeddedCertificates	`256`	Select all certificates embedded in the current entity
sitEmbeddedCRLs	`512`	Select all CRLs embedded in the current entity
sitEmbeddedOCSPs	`1024`	Select all OCSP responses embedded in the current entity
sitEmbeddedRevInfo	`1792`	Select the whole pack of embedded revocation information (certificates, CRLs and OCSPs)
sitUsedCertificates	`4096`	Select all the certificates used to validate this entity's chain
sitUsedCRLs	`8192`	Select all the CRLs used to validate this entity's chain
sitUsedOCSPs	`16384`	Select all the OCSP responses used to validate this entity's chain
sitUsedRevInfo	`28672`	Select the whole pack of revocation information used to validate this entity's chain (certificates, CRLs, OCSP responses)
sitAttributes	`65536`	Select this entity's CMS attributes
sitReferences	`131072`	Select this entity's XML references
sitSignedParts	`262144`	Select this entity's signed parts

Following the call, the relevant pieces of information will be copied to the respective component properties (Certificates, CRLs, OCSPs). Note that you can accumulate information in the properties by making repeated calls to SelectInfo and keeping ClearSelection set to false.

This method is useful if you would like to read/display detailed information about a particular signature or timestamp.

Unsign Method (PDFVerifier Module)

Deletes a signature from the document.

Syntax

Swift
Objective-C

public func unsign(sigLabel: String, unsignKind: Int32) throws -> Void

- (void)unsign:(NSString*)sigLabel :(int)unsignKind;

Remarks

Use this method to delete an existing signature from the document. Use the SigLabel parameter to specify the signature to be removed.

Unsigning is different from GetSignedVersion. The latter returns the revision of the document including the mentioned signature (thus removing anything added after that signature was created). Unsign removes the signature completely by carving it out of the document.

The following unsign kinds are currently supported:


uskDefault (0)	The default option.
uskFull (1)	Remove the signature fully. This is also the default option.
uskKeepField (2)	Only remove the signature, but keep the form field it is in.
uskKeepAppearance (3)	Remove the signature, but keep the form field and its widget.

Note: SigLabel set to "" removes all signatures in the document.

Verify Method (PDFVerifier Module)

Verifies a signed PDF document.

Syntax

Swift
Objective-C

public func verify() throws -> Void

- (void)verify;

Remarks

Use this method to validate all signatures in a PDF document.

This method walks through a signed document and reports every signature via the SignatureFound event. Subscribe to the event to be notified about the signatures and adjust validation settings on the fly.

Upon completion of this method, the signature details will be published in the Signatures property.

This method only validates the signatures, but does not check their coverage. It is a good idea to use mechanisms such as GetSignedVersion or to ensure that the signature covers the expected document revision.

ChainElementDownload Event (PDFVerifier Module)

Fires when there is a need to download a chain element from an online source.

Syntax

Swift
Objective-C

func onChainElementDownload(kind: Int32, certRDN: String, caCertRDN: String, location: String, action: inout Int32)

- (void)onChainElementDownload:(int)kind :(NSString*)certRDN :(NSString*)CACertRDN :(NSString*)location :(int*)action;

Remarks

Subscribe to this event to be notified about validation element retrievals. Use the Action parameter to suppress the download if required.


veaAuto	`0`	Handle the action automatically (the default behaviour)
veaContinue	`1`	Accept the request implied by the event (accept the certificate, allow the object retrieval)
veaReject	`2`	Reject the request implied by the event (reject the certificate, disallow the object retrieval)
veaAcceptNow	`3`	Accept the validated certificate immediately
veaAbortNow	`4`	Abort the validation, reject the certificate


cekUnknown	`0`	Unknown or unsupported element type
cekCertificate	`1`	An X.509 certificate

ChainElementNeeded Event (PDFVerifier Module)

Fires when an element required to validate the chain was not located.

Syntax

Swift
Objective-C

func onChainElementNeeded(kind: Int32, certRDN: String, caCertRDN: String)

- (void)onChainElementNeeded:(int)kind :(NSString*)certRDN :(NSString*)CACertRDN;

Remarks

cekUnknown	`0`	Unknown or unsupported element type
cekCertificate	`1`	An X.509 certificate
cekCRL	`2`	A CRL
cekOCSP	`3`	An OCSP response

ChainValidated Event (PDFVerifier Module)

Reports the completion of a certificate chain validation.

Syntax

Swift
Objective-C

func onChainValidated(index: Int32, entityLabel: String, subjectRDN: String, validationResult: Int32, validationDetails: Int32, cancel: inout Bool)

- (void)onChainValidated:(int)index :(NSString*)entityLabel :(NSString*)subjectRDN :(int)validationResult :(int)validationDetails :(int*)cancel;

Remarks

This event is fired when a certificate chain validation routine completes. SubjectRDN identifies the owner of the validated certificate.

ValidationResult set to 0 (zero) indicates successful chain validation.


cvtValid	`0`	The chain is valid
cvtValidButUntrusted	`1`	The chain is valid, but the root certificate is not trusted
cvtInvalid	`2`	The chain is not valid (some of certificates are revoked, expired, or contain an invalid signature)
cvtCantBeEstablished	`3`	The validity of the chain cannot be established because of missing or unavailable validation information (certificates, CRLs, or OCSP responses)

Any other value reports a failure, and ValidationDetails provides more details on its reasons.


cvrBadData	`0x0001`	One or more certificates in the validation path are malformed
cvrRevoked	`0x0002`	One or more certificates are revoked
cvrNotYetValid	`0x0004`	One or more certificates are not yet valid

cvrUserEnforced	`0x8000`	The chain was considered invalid following intervention from a user code

ChainValidationProgress Event (PDFVerifier Module)

This event is fired multiple times during chain validation to report various stages of the validation procedure.

Syntax

Swift
Objective-C

func onChainValidationProgress(eventKind: String, certRDN: String, caCertRDN: String, action: inout Int32)

- (void)onChainValidationProgress:(NSString*)eventKind :(NSString*)certRDN :(NSString*)CACertRDN :(int*)action;

Remarks

Subscribe to this event to be notified about chain validation progress. Use the Action parameter to alter the validation flow.

The EventKind parameter reports the nature of the event being reported. The CertRDN and CACertRDN parameters report the distinguished names of the certificates that are relevant for the event invocation (one or both can be empty, depending on EventKind). Use the Action parameter to adjust the validation flow.


veaAuto	`0`	Handle the action automatically (the default behaviour)
veaContinue	`1`	Accept the request implied by the event (accept the certificate, allow the object retrieval)
veaReject	`2`	Reject the request implied by the event (reject the certificate, disallow the object retrieval)
veaAcceptNow	`3`	Accept the validated certificate immediately
veaAbortNow	`4`	Abort the validation, reject the certificate

DocumentLoaded Event (PDFVerifier Module)

This event is fired when the document has been loaded into memory.

Syntax

Swift
Objective-C

func onDocumentLoaded(cancel: inout Bool)

- (void)onDocumentLoaded:(int*)cancel;

Remarks

The handler for this event is a good place to check the document structure, which may be useful when preparing the signature. For example, you can use the Pages information to find the optimal position for the signature widget.

Set Cancel to true to terminate document processing on this stage.

Encrypted Event (PDFVerifier Module)

Notifies the application that the document is encrypted and provides recipient certificate details if asymmetric encryption was used to encrypt the document.

Syntax

Swift
Objective-C

func onEncrypted(certUsed: Bool, issuerRDN: String, serialNumber: Data, subjectKeyID: Data, needCredential: Bool, skipThis: inout Bool)

- (void)onEncrypted:(BOOL)certUsed :(NSString*)issuerRDN :(NSData*)serialNumber :(NSData*)subjectKeyID :(BOOL)needCredential :(int*)skipThis;

Remarks

The class fires this event when processing encrypted documents to report the fact of encryption and pass certificate parameters to the user.

This event fires repeatedly for each encryption mechanism used in the document until the user provides the correct credential via the DecryptionCertificate or Password property (depending on the encryption method used), or sets SkipThis to true.

The CertUsed parameter specifies the encryption method used. If set to true, it indicates that the document uses asymmetric (certificate-based) encryption. In that case, the IssuerRDN, SerialNumber, and SubjectKeyID parameters provide the details of the encryption certificate. Note that the document can be encrypted with more than one certificate (or have "more than one recipient"), in which case each certificate will invoke its own Encrypted event loop.

CertUsed set to false indicates that the document uses password encryption. In this case, provide the password via the Password property.

The NeedCredential parameter specifies whether the correct credential is already available to the class or still needs to be set. One example where NeedCredential would be set to false is where it had been provided by the application prior to processing the document (e.g. by setting the Password property to a known pre-defined value). If NeedCredential is set to true, you must provide the valid credential for the decryption process to succeed.

Error Event (PDFVerifier Module)

Information about errors during signing/validation.

Syntax

Swift
Objective-C

func onError(errorCode: Int32, description: String)

- (void)onError:(int)errorCode :(NSString*)description;

Remarks

The event is fired in case of exceptional conditions during PDF processing.

ErrorCode contains an error code and Description contains a textual description of the error.

Notification Event (PDFVerifier Module)

This event notifies the application about an underlying control flow event.

Syntax

Swift
Objective-C

func onNotification(eventID: String, eventParam: String)

- (void)onNotification:(NSString*)eventID :(NSString*)eventParam;

Remarks

The class fires this event to let the application know about some event, occurrence, or milestone in the class. 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 class, the exact action it is performing, or the document being processed, one or both may be omitted.

This class can fire this event with the following EventID values:


DocumentLoaded	Notifies the application that the document has been loaded. This is a backward-compatibility-only notification. Use OnDocumentLoaded event instead.
SignaturesLoaded	Notifies the application that the component has finished loading signatures.
BeforeTimestamp	This event is fired before a timestamp is requested from the timestamping authority. Use the event handler to modify TSA and HTTP settings.
TimestampError	This event is only fired if the class failed to obtain a timestamp from the timestamping authority. The EventParam parameter contains extended error info.
TimestampRequest	A timestamp is requested from the custom timestamping authority. This event is only fired if TimestampServer was set to a virtual:// URI. The EventParam parameter contains the TSP request (or the plain hash, depending on the value provided to TimestampServer), in base16, that needs to be sent to the TSA. Use the event handler to send the request to the TSA. Upon receiving the response, assign it, in base16, to the TimestampResponse configuration property.

SignatureFound Event (PDFVerifier Module)

Signifies the start of signature validation.

Syntax

Swift
Objective-C

func onSignatureFound(index: Int32, entityLabel: String, issuerRDN: String, serialNumber: Data, subjectKeyID: Data, certFound: Bool, validateSignature: inout Bool, validateChain: inout Bool)

- (void)onSignatureFound:(int)index :(NSString*)entityLabel :(NSString*)issuerRDN :(NSData*)serialNumber :(NSData*)subjectKeyID :(BOOL)certFound :(int*)validateSignature :(int*)validateChain;

Remarks

This event tells the application that signature validation is about to start, and provides the details about the signer's certificate via its IssuerRDN, SerialNumber, and SubjectKeyID parameters. It fires for every signature located in the verified document or message.

The CertFound parameter is set to True if the class has found the needed certificate in one of the known locations, and to False otherwise, in which case you must provide it manually via the KnownCertificates property.

Signature validation consists of two independent stages: cryptographic signature validation and chain validation. Separate validation results are reported for each, with the and properties respectively.

Use the ValidateSignature and ValidateChain parameters to tell the verifier which stages to include in the validation.

SignatureValidated Event (PDFVerifier Module)

Marks the completion of the signature validation routine.

Syntax

Swift
Objective-C

func onSignatureValidated(index: Int32, entityLabel: String, issuerRDN: String, serialNumber: Data, subjectKeyID: Data, validationResult: Int32, cancel: inout Bool)

- (void)onSignatureValidated:(int)index :(NSString*)entityLabel :(NSString*)issuerRDN :(NSData*)serialNumber :(NSData*)subjectKeyID :(int)validationResult :(int*)cancel;

Remarks

This event is fired upon the completion of the signature validation routine, and reports the respective validation result.

Use the IssuerRDN, SerialNumber, and/or SubjectKeyID parameters to identify the signing certificate.

ValidationResult is set to 0 if the validation has been successful, or to a non-zero value in case of a validation failure.


svtValid	`0`	The signature is valid
svtUnknown	`1`	Signature validity is unknown
svtCorrupted	`2`	The signature is corrupted
svtSignerNotFound	`3`	Failed to acquire the signing certificate. The signature cannot be validated.
svtFailure	`4`	General failure
svtReferenceCorrupted	`5`	Reference corrupted (XML-based signatures only)

TimestampFound Event (PDFVerifier Module)

Signifies the start of a timestamp validation routine.

Syntax

Swift
Objective-C

func onTimestampFound(index: Int32, entityLabel: String, issuerRDN: String, serialNumber: Data, subjectKeyID: Data, certFound: Bool, validateTimestamp: inout Bool, validateChain: inout Bool)

- (void)onTimestampFound:(int)index :(NSString*)entityLabel :(NSString*)issuerRDN :(NSData*)serialNumber :(NSData*)subjectKeyID :(BOOL)certFound :(int*)validateTimestamp :(int*)validateChain;

Remarks

This event fires for every timestamp identified during signature processing, and reports the details about the signer's certificate via its IssuerRDN, SerialNumber, and SubjectKeyID parameters.

Just like with signature validation, timestamp validation consists of two independent stages: cryptographic signature validation and chain validation. Separate validation results are reported for each, with the and properties respectively.

Use the ValidateSignature and ValidateChain parameters to tell the verifier which stages to include in the validation.

TimestampValidated Event (PDFVerifier Module)

Reports the completion of the timestamp validation routine.

Syntax

Swift
Objective-C

func onTimestampValidated(index: Int32, entityLabel: String, issuerRDN: String, serialNumber: Data, subjectKeyID: Data, time: String, validationResult: Int32, chainValidationResult: Int32, chainValidationDetails: Int32, cancel: inout Bool)

- (void)onTimestampValidated:(int)index :(NSString*)entityLabel :(NSString*)issuerRDN :(NSData*)serialNumber :(NSData*)subjectKeyID :(NSString*)time :(int)validationResult :(int)chainValidationResult :(int)chainValidationDetails :(int*)cancel;

Remarks

This event is fired upon the completion of the timestamp validation routine, and reports the respective validation result.

ValidationResult is set to 0 if the validation has been successful, or to a non-zero value in case of a failure.


svtValid	`0`	The signature is valid
svtUnknown	`1`	Signature validity is unknown
svtCorrupted	`2`	The signature is corrupted
svtSignerNotFound	`3`	Failed to acquire the signing certificate. The signature cannot be validated.
svtFailure	`4`	General failure
svtReferenceCorrupted	`5`	Reference corrupted (XML-based signatures only)

TLSCertNeeded Event (PDFVerifier 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 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 (PDFVerifier 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 the TLSServerChain property to access the certificate chain. In general, classes 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 class, and can be adjusted if needed.

TLSEstablished Event (PDFVerifier 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 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 (PDFVerifier 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 by the TLSEstablished event. If the server chooses to request a client certificate, the TLSCertNeeded event will also be fired.

TLSShutdown Event (PDFVerifier 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

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: ""

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.

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.

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.

Creates a new TLSSettings object.

Config Settings (PDFVerifier 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.

PDFVerifier Config Settings

AlternateName: TBD.

TBD

AsyncDocumentID: Specifies the document ID for SignAsyncEnd() call.

Use this property when working with multi-signature DCAuth requests and responses to uniquely identify documents signed within a larger batch.

BuildApplicationName: Specifies the application name used to create the signature.

Use this property to set the application name used to create the signature.

For advanced settings of the build properties, use the BuildProperties configuration setting.

BuildApplicationVersion: Specifies the application version used to create the signature.

Use this property to set the application version used to create the signature.

For advanced settings of the build properties, use the BuildProperties configuration setting.

BuildProperties: Specifies the build properties of the signature.

Use this property to set the build properties of the signature in JSON format. Names of JSON fields correspond to the entry names in Adobe's Digital Signature Build Dictionary Specification.

Sample value: { "App":{ "Name":"TestApp", "REx":"8.0.0" } }

The above value sets the application name and version used to create the signature. The same result could be achieved using the BuildApplicationName and BuildApplicationVersion configuration settings.

Sample value 2: { "App":{ "Name":"TestApp", "REx":"8.0.0", "R":524288, "Date":"2023-01-01 00:01", "OS":[ "Win" ], "TrustedMode":true }, "Filter":{ "Name":"TestFilter", "R":131101, "Date":"2023-01-01 00:02", "PreRelease":true }, "PubSec":{ "R":13102, "Date":"2023-01-01 00:03", "PreRelease":true, "NonEFontNoWarn":true } }

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

Use this property 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.

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

Use this property 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.

ChainCurrentCACert: Returns the current CA certificate.

This property returns the CA certificate that is used on the current step.

ChainCurrentCert: Returns the certificate that is currently being validated.

Use this property to obtain the body of the certificate that is currently being validated.

ChainCurrentCRL: Returns the current CRL.

Returns the CRL object that is currently being processed.

ChainCurrentCRLSize: Returns the size of the current CRL.

This property returns the size of the CRL object that is currently being processed.

ChainCurrentOCSP: Returns the current OCSP response.

Returns the OCSP object that is currently being processed.

ChainCurrentOCSPSigner: Returns the signer of the current OCSP object.

Returns the signer/CA that has issued the OCSP response that is currently being processed.

ChainInterimDetails: Returns the current interim validation details.

This property returns the interim chain validation details.

ChainInterimResult: Returns the current interim validation result.

Use this setting to obtain the current (mid-chain) validation result. This property applies to the current validation step and may change as the chain walk proceeds. The final result will be published in the ChainValidationResult property once the validation process completes.

CheckValidityPeriodForTrusted: Whether to check validity period for trusted certificates.

Whether to check validity period for trusted certificates.

ConfigPreferLegacyLevels: Indicates whether legacy signature levels should be preferred.

Set this property to True to instruct the validation engine to prioritize legacy PAdES signature levels (BES, EPES, LTV) over Baseline levels (B-B, B-T, B-LT, B-LTA) when a signature can be determined as multiple levels.

TBD

CustomSignedAttributes: TBD.

TBD

CustomTrustedLists: Specifies the custom TrustedLists.

Use this property to specify the custom TSLs (Trust Service status Lists) to the validator. The URLs list is comma-separated.

CustomTSLs: Specifies the custom TrustedLists.

Use this property to specify the custom TSLs (Trust Service status Lists) to the validator. The URLs list is comma-separated.

CustomUnsignedAttributes: TBD.

TBD

DislikeOpenEndedOCSPs: Tells the class to discourage OCSP responses without an explicit NextUpdate parameter.

When this property is set to True, the validation engine treats OCSP response without a NextUpdate field as 'substandard' and tries to obtain some further revocation material for the certificate in question (a different OCSP or a CRL, even if the class is configured to prefer the OCSP route). This is to work around Adobe Reader's intolerance to such OCSPs when classifying signed documents as LTV (as of August 2022).

DocumentVersion: The document version from the PDF document header.

This property contains the PDF document version provided in the document header. The version is returned in the form "Major.Minor": for example, PDF-1.7 will be returned as "1.7", and PDF-2.0 as "2.0".

IgnoreOCSPNoCheckExtension: Whether the OCSP NoCheck extension should be ignored.

Set this property to True to make the validation engine ignore the OCSP no-check extension. You would normally need to set this property when validating severely non-compliant chains that misuse the extension, causing chain loops or other validation issues.

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.

Set this property to True to instruct the validation engine to disregard the validity of the timestamp signer certificate chain when determining the signature level.

TBD

ImplicitlyTrustSelfSignedCertificates: Whether to trust self-signed certificates.

Set this property to True to implicitly trust all self-signed certificates. Use it with care as trusting just about every self-signed certificate is unwise. One exceptional reason where this property may be handy is where a chain is validated in an environment that is not supposed to trust it (for example, a signing, rather than verifying environment, or a QA server). Trusting all self-signing certificates (which are normally trusted) allows emulating the verifying environment without actually changing its security settings.

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.

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.
