The PDFVerifier component verifies signatures over PDF documents.
Syntax
nsoftware.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 SignatureValidationResult and ChainValidationResult 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 CoverageEndsAt 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 component:
- 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.
- ValidatedSigningTime returns the signing time as recorded in the embedded signature timestamp. This is in contrast to ClaimedSigningTime, which returns the signing time as specified by the signer.
- ValidationLog 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.

Remarks
Use this property to provide the decryption password.
Profile Property (PDFVerifier Component)
Specifies a pre-defined profile to apply when creating the signature.
Syntax
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.
Proxy Property (PDFVerifier Component)
The proxy server settings.
Syntax
public ProxySettings Proxy { get; }
Public ReadOnly Property Proxy As ProxySettings
Remarks
Use this property to tune up the proxy server settings.

Enum PDFVerifierRevocationChecks crcNone crcAuto crcAllCRL crcAllOCSP crcAllCRLAndOCSP crcAnyCRL crcAnyOCSP crcAnyCRLOrOCSP crcAnyOCSPOrCRL End Enum
Default Value
1
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.
Signatures Property (PDFVerifier Component)

Syntax
public PDFSignatureList Signatures { get; }
Public ReadOnly Property Signatures As PDFSignatureList
Remarks
Upon completion of the validation process conducted by the Verify method, all the signature details are populated in this property.
This property is read-only and not available at design time.
Please refer to the PDFSignature type for a complete list of fields.SocketSettings Property (PDFVerifier Component)
Manages network connection settings.
Syntax
public SocketSettings SocketSettings { get; }
Public ReadOnly Property SocketSettings As SocketSettings
Remarks
Use this property to tune up network connection parameters.
This property is read-only.
Please refer to the SocketSettings type for a complete list of fields.Timestamps Property (PDFVerifier Component)
Contains a collection of timestamps for the processed document.
Syntax
public TimestampInfoList Timestamps { get; }
Public ReadOnly Property Timestamps As TimestampInfoList
Remarks
Use this property to access the timestamps included in the processed document.
This property is read-only and not available at design time.
Please refer to the TimestampInfo type for a complete list of fields.TLSClientChain Property (PDFVerifier Component)
The TLS client certificate chain.
Syntax
public CertificateList TLSClientChain { get; }
Public Property TLSClientChain As CertificateList
Remarks
Assign a certificate chain to this property to enable TLS client authentication in the component. Note that the client's end-entity certificate should have a private key associated with it.
Use the CertificateStorage or CertificateManager components to import the certificate from a file, system store, or PKCS11 device.
This property is not available at design time.
Please refer to the Certificate type for a complete list of fields.TLSServerChain Property (PDFVerifier Component)
The TLS server's certificate chain.
Syntax
public CertificateList TLSServerChain { get; }
Public ReadOnly Property TLSServerChain As CertificateList
Remarks
Use this property to access the certificate chain sent by the TLS server. This property is ready to read when the TLSCertValidate event is fired by the client component.
This property is read-only and not available at design time.
Please refer to the Certificate type for a complete list of fields.TLSSettings Property (PDFVerifier Component)
Manages TLS layer settings.
Syntax
public TLSSettings TLSSettings { get; }
Public ReadOnly Property TLSSettings As TLSSettings
Remarks
Use this property to tune up the TLS layer parameters.
This property is read-only.
Please refer to the TLSSettings type for a complete list of fields.TrustedCertificates Property (PDFVerifier Component)
A list of trusted certificates for chain validation.
Syntax
public CertificateList TrustedCertificates { get; }
Public Property TrustedCertificates As CertificateList
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.
This property is not available at design time.
Please refer to the Certificate type for a complete list of fields.ValidationMoment Property (PDFVerifier Component)
The time point at which signature validity is to be established.
Syntax
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 Component)
Closes an opened document.
Syntax
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 Component)
Sets or retrieves a configuration setting.
Syntax
Remarks
Config is a generic method available in every component. It is used to set and retrieve configuration settings for the component.
These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, 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 Component)
Performs an additional action.
Syntax
Remarks
DoAction is a generic method available in every component. 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 Component)

Remarks
Use this method to retrieve the contents of an attached file and save it to a file.
GetAttachedStream Method (PDFVerifier Component)
Saves a PDF attachment to a stream.
Syntax
public void GetAttachedStream(int index, System.IO.Stream stream);
Public Sub GetAttachedStream(ByVal Index As Integer, ByVal Stream As System.IO.Stream)
Remarks
Use this method to retrieve the contents of an attached file and save it to a stream.
GetSignedVersion Method (PDFVerifier Component)
Returns the part of the document that is covered by the signature.
Syntax
Public Sub GetSignedVersion(ByVal SigLabel As String)
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 CoverageEndsAt field of the signature object and match it to the document length.
Open Method (PDFVerifier Component)
Opens a document for verifying or removing signatures.
Syntax
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 Component)
Resets the component settings.
Syntax
public void Reset();
Public Sub Reset()
Remarks
Reset is a generic method available in every component.
Revalidate Method (PDFVerifier Component)
Revalidates a signature in accordance with current settings.
Syntax
Remarks
Use this method to revalidate a signature in the opened PDF document.
SelectInfo Method (PDFVerifier Component)
Select signature information for a specific entity.
Syntax
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 Component)
Deletes a signature from the document.
Syntax
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 Component)
Verifies a signed PDF document.
Syntax
public void Verify();
Public Sub 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 CoverageEndsAt to ensure that the signature covers the expected document revision.
ChainElementDownload Event (PDFVerifier Component)
Fires when there is a need to download a chain element from an online source.
Syntax
public event OnChainElementDownloadHandler OnChainElementDownload; public delegate void OnChainElementDownloadHandler(object sender, PDFVerifierChainElementDownloadEventArgs e); public class PDFVerifierChainElementDownloadEventArgs : EventArgs { public int Kind { get; } public string CertRDN { get; } public string CACertRDN { get; } public string Location { get; } public int Action { get; set; } }
Public Event OnChainElementDownload As OnChainElementDownloadHandler Public Delegate Sub OnChainElementDownloadHandler(sender As Object, e As PDFVerifierChainElementDownloadEventArgs) Public Class PDFVerifierChainElementDownloadEventArgs Inherits EventArgs Public ReadOnly Property Kind As Integer Public ReadOnly Property CertRDN As String Public ReadOnly Property CACertRDN As String Public ReadOnly Property Location As String Public Property Action As Integer End Class
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 |

Syntax
public event OnChainElementNeededHandler OnChainElementNeeded; public delegate void OnChainElementNeededHandler(object sender, PDFVerifierChainElementNeededEventArgs e); public class PDFVerifierChainElementNeededEventArgs : EventArgs { public int Kind { get; } public string CertRDN { get; } public string CACertRDN { get; } }
Public Event OnChainElementNeeded As OnChainElementNeededHandler Public Delegate Sub OnChainElementNeededHandler(sender As Object, e As PDFVerifierChainElementNeededEventArgs) Public Class PDFVerifierChainElementNeededEventArgs Inherits EventArgs Public ReadOnly Property Kind As Integer Public ReadOnly Property CertRDN As String Public ReadOnly Property CACertRDN As String End Class
Remarks
Subscribe to this event to be notified about missing validation elements. Use the KnownCRLs, KnownCertificates, and KnownOCSPs properties in the event handler to provide the missing piece.
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 Component)
Reports the completion of a certificate chain validation.
Syntax
public event OnChainValidatedHandler OnChainValidated; public delegate void OnChainValidatedHandler(object sender, PDFVerifierChainValidatedEventArgs e); public class PDFVerifierChainValidatedEventArgs : EventArgs { public int Index { get; } public string EntityLabel { get; } public string SubjectRDN { get; } public int ValidationResult { get; } public int ValidationDetails { get; } public bool Cancel { get; set; } }
Public Event OnChainValidated As OnChainValidatedHandler Public Delegate Sub OnChainValidatedHandler(sender As Object, e As PDFVerifierChainValidatedEventArgs) Public Class PDFVerifierChainValidatedEventArgs Inherits EventArgs Public ReadOnly Property Index As Integer Public ReadOnly Property EntityLabel As String Public ReadOnly Property SubjectRDN As String Public ReadOnly Property ValidationResult As Integer Public ReadOnly Property ValidationDetails As Integer Public Property Cancel As Boolean End Class
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) |

ChainValidationProgress Event (PDFVerifier Component)
This event is fired multiple times during chain validation to report various stages of the validation procedure.
Syntax
public event OnChainValidationProgressHandler OnChainValidationProgress; public delegate void OnChainValidationProgressHandler(object sender, PDFVerifierChainValidationProgressEventArgs e); public class PDFVerifierChainValidationProgressEventArgs : EventArgs { public string EventKind { get; } public string CertRDN { get; } public string CACertRDN { get; } public int Action { get; set; } }
Public Event OnChainValidationProgress As OnChainValidationProgressHandler Public Delegate Sub OnChainValidationProgressHandler(sender As Object, e As PDFVerifierChainValidationProgressEventArgs) Public Class PDFVerifierChainValidationProgressEventArgs Inherits EventArgs Public ReadOnly Property EventKind As String Public ReadOnly Property CertRDN As String Public ReadOnly Property CACertRDN As String Public Property Action As Integer End Class
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 Component)
This event is fired when the document has been loaded into memory.
Syntax
public event OnDocumentLoadedHandler OnDocumentLoaded; public delegate void OnDocumentLoadedHandler(object sender, PDFVerifierDocumentLoadedEventArgs e); public class PDFVerifierDocumentLoadedEventArgs : EventArgs { public bool Cancel { get; set; } }
Public Event OnDocumentLoaded As OnDocumentLoadedHandler Public Delegate Sub OnDocumentLoadedHandler(sender As Object, e As PDFVerifierDocumentLoadedEventArgs) Public Class PDFVerifierDocumentLoadedEventArgs Inherits EventArgs Public Property Cancel As Boolean End Class
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 Component)
Notifies the application that the document is encrypted and provides recipient certificate details if asymmetric encryption was used to encrypt the document.
Syntax
public event OnEncryptedHandler OnEncrypted; public delegate void OnEncryptedHandler(object sender, PDFVerifierEncryptedEventArgs e); public class PDFVerifierEncryptedEventArgs : EventArgs { public bool CertUsed { get; } public string IssuerRDN { get; } public byte[] SerialNumber { get; } public byte[] SubjectKeyID { get; } public bool NeedCredential { get; } public bool SkipThis { get; set; } }
Public Event OnEncrypted As OnEncryptedHandler Public Delegate Sub OnEncryptedHandler(sender As Object, e As PDFVerifierEncryptedEventArgs) Public Class PDFVerifierEncryptedEventArgs Inherits EventArgs Public ReadOnly Property CertUsed As Boolean Public ReadOnly Property IssuerRDN As String Public ReadOnly Property SerialNumber As Byte() Public ReadOnly Property SubjectKeyID As Byte() Public ReadOnly Property NeedCredential As Boolean Public Property SkipThis As Boolean End Class
Remarks
The component 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 component 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 Component)
Information about errors during signing/validation.
Syntax
public event OnErrorHandler OnError; public delegate void OnErrorHandler(object sender, PDFVerifierErrorEventArgs e); public class PDFVerifierErrorEventArgs : EventArgs { public int ErrorCode { get; } public string Description { get; } }
Public Event OnError As OnErrorHandler Public Delegate Sub OnErrorHandler(sender As Object, e As PDFVerifierErrorEventArgs) Public Class PDFVerifierErrorEventArgs Inherits EventArgs Public ReadOnly Property ErrorCode As Integer Public ReadOnly Property Description As String End Class
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 Component)
This event notifies the application about an underlying control flow event.
Syntax
public event OnNotificationHandler OnNotification; public delegate void OnNotificationHandler(object sender, PDFVerifierNotificationEventArgs e); public class PDFVerifierNotificationEventArgs : EventArgs { public string EventID { get; } public string EventParam { get; } }
Public Event OnNotification As OnNotificationHandler Public Delegate Sub OnNotificationHandler(sender As Object, e As PDFVerifierNotificationEventArgs) Public Class PDFVerifierNotificationEventArgs Inherits EventArgs Public ReadOnly Property EventID As String Public ReadOnly Property EventParam As String End Class
Remarks
The component fires this event to let the application know about some event, occurrence, or milestone in the component. For example, it may fire to report completion of the document processing. The list of events being reported is not fixed, and may be flexibly extended over time.
The unique identifier of the event is provided in the EventID parameter. EventParam contains any parameters accompanying the occurrence. Depending on the type of the component, the exact action it is performing, or the document being processed, one or both may be omitted.
This component 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 component 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 Component)
Signifies the start of signature validation.
Syntax
public event OnSignatureFoundHandler OnSignatureFound; public delegate void OnSignatureFoundHandler(object sender, PDFVerifierSignatureFoundEventArgs e); public class PDFVerifierSignatureFoundEventArgs : EventArgs { public int Index { get; } public string EntityLabel { get; } public string IssuerRDN { get; } public byte[] SerialNumber { get; } public byte[] SubjectKeyID { get; } public bool CertFound { get; } public bool ValidateSignature { get; set; } public bool ValidateChain { get; set; } }
Public Event OnSignatureFound As OnSignatureFoundHandler Public Delegate Sub OnSignatureFoundHandler(sender As Object, e As PDFVerifierSignatureFoundEventArgs) Public Class PDFVerifierSignatureFoundEventArgs Inherits EventArgs Public ReadOnly Property Index As Integer Public ReadOnly Property EntityLabel As String Public ReadOnly Property IssuerRDN As String Public ReadOnly Property SerialNumber As Byte() Public ReadOnly Property SubjectKeyID As Byte() Public ReadOnly Property CertFound As Boolean Public Property ValidateSignature As Boolean Public Property ValidateChain As Boolean End Class
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 component 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 SignatureValidationResult and ChainValidationResult properties respectively.
Use the ValidateSignature and ValidateChain parameters to tell the verifier which stages to include in the validation.
SignatureValidated Event (PDFVerifier Component)
Marks the completion of the signature validation routine.
Syntax
public event OnSignatureValidatedHandler OnSignatureValidated; public delegate void OnSignatureValidatedHandler(object sender, PDFVerifierSignatureValidatedEventArgs e); public class PDFVerifierSignatureValidatedEventArgs : EventArgs { public int Index { get; } public string EntityLabel { get; } public string IssuerRDN { get; } public byte[] SerialNumber { get; } public byte[] SubjectKeyID { get; } public int ValidationResult { get; } public bool Cancel { get; set; } }

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 Component)

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.
The CertFound parameter is set to True if the component 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.
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 ValidationResult and ChainValidationResult properties respectively.
Use the ValidateSignature and ValidateChain parameters to tell the verifier which stages to include in the validation.
TimestampValidated Event (PDFVerifier Component)
Reports the completion of the timestamp validation routine.
Syntax
public event OnTimestampValidatedHandler OnTimestampValidated; public delegate void OnTimestampValidatedHandler(object sender, PDFVerifierTimestampValidatedEventArgs e); public class PDFVerifierTimestampValidatedEventArgs : EventArgs { public int Index { get; } public string EntityLabel { get; } public string IssuerRDN { get; } public byte[] SerialNumber { get; } public byte[] SubjectKeyID { get; } public string Time { get; } public int ValidationResult { get; } public int ChainValidationResult { get; } public int ChainValidationDetails { get; } public bool Cancel { get; set; } }

Syntax
public event OnTLSCertNeededHandler OnTLSCertNeeded; public delegate void OnTLSCertNeededHandler(object sender, PDFVerifierTLSCertNeededEventArgs e); public class PDFVerifierTLSCertNeededEventArgs : EventArgs { public string Host { get; } public string CANames { get; } }
Public Event OnTLSCertNeeded As OnTLSCertNeededHandler Public Delegate Sub OnTLSCertNeededHandler(sender As Object, e As PDFVerifierTLSCertNeededEventArgs) Public Class PDFVerifierTLSCertNeededEventArgs Inherits EventArgs Public ReadOnly Property Host As String Public ReadOnly Property CANames As String End Class
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 Component)
This event is fired upon receipt of the TLS server's certificate, allowing the user to control its acceptance.
Syntax
public event OnTLSCertValidateHandler OnTLSCertValidate; public delegate void OnTLSCertValidateHandler(object sender, PDFVerifierTLSCertValidateEventArgs e); public class PDFVerifierTLSCertValidateEventArgs : EventArgs { public string ServerHost { get; } public string ServerIP { get; } public bool Accept { get; set; } }
Public Event OnTLSCertValidate As OnTLSCertValidateHandler Public Delegate Sub OnTLSCertValidateHandler(sender As Object, e As PDFVerifierTLSCertValidateEventArgs) Public Class PDFVerifierTLSCertValidateEventArgs Inherits EventArgs Public ReadOnly Property ServerHost As String Public ReadOnly Property ServerIP As String Public Property Accept As Boolean End Class
Remarks
This event is fired during a TLS handshake. Use the TLSServerChain property to access the certificate chain. In general, components may contact a number of TLS endpoints during their work, depending on their configuration.
Accept is assigned in accordance with the outcome of the internal validation check performed by the component, and can be adjusted if needed.
TLSEstablished Event (PDFVerifier Component)
Fires when a TLS handshake with Host successfully completes.
Syntax
public event OnTLSEstablishedHandler OnTLSEstablished; public delegate void OnTLSEstablishedHandler(object sender, PDFVerifierTLSEstablishedEventArgs e); public class PDFVerifierTLSEstablishedEventArgs : EventArgs { public string Host { get; } public string Version { get; } public string Ciphersuite { get; } public byte[] ConnectionId { get; } public bool Abort { get; set; } }
Public Event OnTLSEstablished As OnTLSEstablishedHandler Public Delegate Sub OnTLSEstablishedHandler(sender As Object, e As PDFVerifierTLSEstablishedEventArgs) Public Class PDFVerifierTLSEstablishedEventArgs Inherits EventArgs Public ReadOnly Property Host As String Public ReadOnly Property Version As String Public ReadOnly Property Ciphersuite As String Public ReadOnly Property ConnectionId As Byte() Public Property Abort As Boolean End Class
Remarks
The component 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 Component)
Fires when a new TLS handshake is initiated, before the handshake commences.
Syntax
public event OnTLSHandshakeHandler OnTLSHandshake; public delegate void OnTLSHandshakeHandler(object sender, PDFVerifierTLSHandshakeEventArgs e); public class PDFVerifierTLSHandshakeEventArgs : EventArgs { public string Host { get; } public bool Abort { get; set; } }
Public Event OnTLSHandshake As OnTLSHandshakeHandler Public Delegate Sub OnTLSHandshakeHandler(sender As Object, e As PDFVerifierTLSHandshakeEventArgs) Public Class PDFVerifierTLSHandshakeEventArgs Inherits EventArgs Public ReadOnly Property Host As String Public Property Abort As Boolean End Class
Remarks
The component 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 Component)
Reports the graceful closure of a TLS connection.
Syntax
public event OnTLSShutdownHandler OnTLSShutdown; public delegate void OnTLSShutdownHandler(object sender, PDFVerifierTLSShutdownEventArgs e); public class PDFVerifierTLSShutdownEventArgs : EventArgs { public string Host { get; } }
Public Event OnTLSShutdown As OnTLSShutdownHandler Public Delegate Sub OnTLSShutdownHandler(sender As Object, e As PDFVerifierTLSShutdownEventArgs) Public Class PDFVerifierTLSShutdownEventArgs Inherits EventArgs Public ReadOnly Property Host As String End Class
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.
Fields
Bytes
byte[] (read-only)
Default: ""
Returns the raw certificate data in DER format.
CA
bool
Default: 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 field when generating a new certificate to have its Basic Constraints extension generated automatically.
CAKeyID
byte[] (read-only)
Default: ""
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 SubjectKeyID setting, and for lower-level certificates, from the parent certificate's subject key ID extension.
CertType
CertTypes (read-only)
Default: 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 component to load or create new certificate and certificate requests objects.
CRLDistributionPoints
string
Default: ""
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 field 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: ""
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: ""
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: ""
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.
HashAlgorithm
string
Default: ""
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 SigAlgorithm to find out the hash algorithm that is part of the certificate signature.

Use the KeyBits, Curve, and PublicKeyBytes fields to get more details about the key the certificate contains.
KeyBits
int (read-only)
Default: 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 PublicKeyBytes or PrivateKeyBytes field would typically contain auxiliary values, and therefore be longer.
KeyFingerprint
string (read-only)
Default: ""
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 Fingerprint field. The key fingeprint uniquely identifies the public key, and so can be the same for multiple certificates containing the same key.
KeyUsage
int
Default: 0
Indicates the purposes of the key contained in the certificate, in the form of an OR'ed flag set.
This value is a bit mask of the following values:
ckuUnknown | 0x00000 | Unknown key usage |
ckuDigitalSignature | 0x00001 | Digital signature |
ckuNonRepudiation | 0x00002 | Non-repudiation |
ckuKeyEncipherment | 0x00004 | Key encipherment |
ckuDataEncipherment | 0x00008 | Data encipherment |
ckuKeyAgreement | 0x00010 | Key agreement |
ckuKeyCertSign | 0x00020 | Certificate signing |

Set this field before generating the certificate to propagate the key usage flags to the new certificate.
KeyValid
bool (read-only)
Default: False
Returns True if the certificate's key is cryptographically valid, and False otherwise.
OCSPLocations
string
Default: ""
Locations of OCSP services that can be used to check this certificate's validity in real time, as recorded by the CA.
Set this field 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: False
Accessor to the value of the certificate's ocsp-no-check extension.
Origin
int (read-only)
Default: 0
Returns the location that the certificate was taken or loaded from.
PolicyIDs
string
Default: ""
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 field 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
byte[] (read-only)
Default: ""
Returns the certificate's private key in DER-encoded format. It is normal for this field 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: 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 field is independent from PrivateKeyBytes, 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: False
Indicates whether the private key is extractable (exportable).
PublicKeyBytes
byte[] (read-only)
Default: ""
Contains the certificate's public key in DER format.
This typically would contain an ASN.1-encoded public key value. The exact format depends on the type of the public key contained in the certificate.
Qualified
bool (read-only)
Default: 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: 0
Returns a simplified qualified status of the certificate.
Qualifiers
string (read-only)
Default: ""
A list of qualifiers.
Contains a comma-separated list of qualifier aliases for the certificate, for example QCP-n-qscd,QCWithSSCD.
SelfSigned
bool (read-only)
Default: False
Indicates whether the certificate is self-signed (root) or signed by an external CA.
SerialNumber
byte[]
Default: ""
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: ""
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: 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: ""
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 SubjectRDN.
SubjectAlternativeName
string
Default: ""
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 SubjectRDN 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
byte[]
Default: ""
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 SubjectKeyID and CAKeyID fields 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: ""
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: 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: ""
The time point at which the certificate becomes valid, in UTC.
ValidTo
string
Default: ""
The time point at which the certificate expires, in UTC.

bool
Default: False
Whether to force TLS session resumption when the destination address changes.
PreSharedIdentity
string
Default: ""
Defines the identity used when the PSK (Pre-Shared Key) key-exchange mechanism is negotiated.
PreSharedKey
string
Default: ""
Contains the pre-shared key for the PSK (Pre-Shared Key) key-exchange mechanism, encoded with base16.
PreSharedKeyCiphersuite
string
Default: ""
Defines the ciphersuite used for PSK (Pre-Shared Key) negotiation.
RenegotiationAttackPreventionMode
RenegotiationAttackPreventionModes
Default: 2
Selects the renegotiation attack prevention mechanism.
The following options are available:
crapmCompatible | 0 | TLS 1.0 and 1.1 compatibility mode (renegotiation indication extension is disabled). |
crapmStrict | 1 | Renegotiation attack prevention is enabled and enforced. |
crapmAuto | 2 | Automatically choose whether to enable or disable renegotiation attack prevention. |
RevocationCheck
RevocationCheckKinds
Default: 1
Specifies the kind(s) of revocation check to perform.
Revocation checking is necessary to ensure the integrity of the chain and obtain up-to-date certificate validity and trustworthiness information.
crcNone | 0 | No revocation checking. |
crcAuto | 1 | Automatic mode selection. Currently this maps to crcAnyOCSPOrCRL, but it may change in the future. |
crcAllCRL | 2 | All provided CRL endpoints will be checked, and all checks must succeed. |
crcAllOCSP | 3 | All provided OCSP endpoints will be checked, and all checks must succeed. |
crcAllCRLAndOCSP | 4 | All provided CRL and OCSP endpoints will be checked, and all checks must succeed. |
crcAnyCRL | 5 | All provided CRL endpoints will be checked, and at least one check must succeed. |
crcAnyOCSP | 6 | All provided OCSP endpoints will be checked, and at least one check must succeed. |
crcAnyCRLOrOCSP | 7 | All provided CRL and OCSP endpoints will be checked, and at least one check must succeed. CRL endpoints are checked first. |
crcAnyOCSPOrCRL | 8 | All provided CRL and OCSP endpoints will be checked, and at least one check must succeed. OCSP endpoints are checked first. |
This setting controls the way the revocation checks are performed for every certificate in the chain. Typically certificates come with two types of revocation information sources: CRL (certificate revocation lists) and OCSP responders. CRLs are static objects periodically published by the CA at some online location. OCSP responders are active online services maintained by the CA that can provide up-to-date information on certificate statuses in near real time.
There are some conceptual differences between the two. CRLs are normally larger in size. Their use involves some latency because there is normally some delay between the time when a certificate was revoked and the time the subsequent CRL mentioning that is published. The benefits of CRL is that the same object can provide statuses for all certificates issued by a particular CA, and that the whole technology is much simpler than OCSP (and thus is supported by more CAs).
This setting lets you adjust the validation course by including or excluding certain types of revocation sources from the validation process. The crcAnyOCSPOrCRL setting (give preference to the faster OCSP route and only demand one source to succeed) is a good choice for most typical validation environments. The "crcAll*" modes are much stricter, and may be used in scenarios where bulletproof validity information is essential.
Note: If no CRL or OCSP endpoints are provided by the CA, the revocation check will be considered successful. This is because the CA chose not to supply revocation information for its certificates, meaning they are considered irrevocable.
Note: Within each of the above settings, if any retrieved CRL or OCSP response indicates that the certificate has been revoked, the revocation check fails.
SSLOptions
int
Default: 16
Various SSL (TLS) protocol options, set of
cssloExpectShutdownMessage | 0x001 | Wait for the close-notify message when shutting down the connection |
