  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 (CRL) and Online Certificate Status Protocol (OCSP) responses serve the same purpose of ensuring that the certificate had not been revoked by the Certificate Authority (CA) at the time of use.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.

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

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 Their use involves some latency because there is normally some delay between the time when a certificate was revoked and the time the subsequent CRL mentioning that is published.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

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

Syntax

• C#
• VB.NET

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 than that of 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.

ValidationMoment Property (XAdESVerifier Component)

Public Function Config(ByVal ConfigurationString As String) As String

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.

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

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

ReferenceValidated Event (XAdESVerifier Component)

Marks the end of a reference validation.

Syntax

• C#
• VB.NET

public event OnReferenceValidatedHandler OnReferenceValidated;

public delegate void OnReferenceValidatedHandler(object sender, XadesverifierReferenceValidatedEventArgs e);

public class XadesverifierReferenceValidatedEventArgs : EventArgs {
  public int ReferenceIndex { get; }
  public string ID { get; }
  public string URI { get; }
  public string RefType { get; }
  public bool DigestValid { get; }
}

Public Event OnReferenceValidated As OnReferenceValidatedHandler

Public Delegate Sub OnReferenceValidatedHandler(sender As Object, e As XadesverifierReferenceValidatedEventArgs)

Public Class XadesverifierReferenceValidatedEventArgs Inherits EventArgs
  Public ReadOnly Property ReferenceIndex As Integer
  Public ReadOnly Property ID As String
  Public ReadOnly Property URI As String
  Public ReadOnly Property RefType As String
  Public ReadOnly Property DigestValid As Boolean
End Class

Remarks

The component fires this event to report completion of a reference validation. A reference is a building block of a signature as it binds signature coverage to a particular piece of the document.

ResolveReference Event (XAdESVerifier Component)

Asks the application to resolve a reference.

Syntax

• C#
• VB.NET

public event OnResolveReferenceHandler OnResolveReference;

public delegate void OnResolveReferenceHandler(object sender, XadesverifierResolveReferenceEventArgs e);

public class XadesverifierResolveReferenceEventArgs : EventArgs {
  public int ReferenceIndex { get; }
  public string URI { get; }
}

Public Event OnResolveReference As OnResolveReferenceHandler

Public Delegate Sub OnResolveReferenceHandler(sender As Object, e As XadesverifierResolveReferenceEventArgs)

Public Class XadesverifierResolveReferenceEventArgs Inherits EventArgs
  Public ReadOnly Property ReferenceIndex As Integer
  Public ReadOnly Property URI As String
End Class

Remarks

This event is fired when the control could not automatically resolve a reference and requires custom treatment.

URI contains a reference to the data.

ReferenceIndex specifies the index of the reference to process.

Based on the reference's URI the event handler should set either TargetXMLElement or TargetData property of the reference.

SignatureFound Event (XAdESVerifier Component)

Signifies the start of signature validation.

Syntax

• C#
• VB.NET

public event OnSignatureFoundHandler OnSignatureFound;

public delegate void OnSignatureFoundHandler(object sender, XadesverifierSignatureFoundEventArgs e);

public class XadesverifierSignatureFoundEventArgs : EventArgs {
  public int Index { 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 XadesverifierSignatureFoundEventArgs)

Public Class XadesverifierSignatureFoundEventArgs Inherits EventArgs
  Public ReadOnly Property Index As Integer
  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 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 KnownCertificates property.

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

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

SignatureValidated Event (XAdESVerifier Component)

Reports the signature validation result.

Syntax

• C#
• VB.NET

public event OnSignatureValidatedHandler OnSignatureValidated;

public delegate void OnSignatureValidatedHandler(object sender, XadesverifierSignatureValidatedEventArgs e);

public class XadesverifierSignatureValidatedEventArgs : EventArgs {
  public int SigIndex { get; }
  public string IssuerRDN { get; }
  public byte[] SerialNumber { get; }
  public byte[] SubjectKeyID { get; }
  public int ValidationResult { get; }
}

Public Event OnSignatureValidated As OnSignatureValidatedHandler

Public Delegate Sub OnSignatureValidatedHandler(sender As Object, e As XadesverifierSignatureValidatedEventArgs)

Public Class XadesverifierSignatureValidatedEventArgs Inherits EventArgs
  Public ReadOnly Property SigIndex As Integer
  Public ReadOnly Property IssuerRDN As String
  Public ReadOnly Property SerialNumber As Byte()
  Public ReadOnly Property SubjectKeyID As Byte()
  Public ReadOnly Property ValidationResult As Integer
End Class

Remarks

This event is fired when the complete XML signature validation process is finished. IssuerRDN returns the name of the signature issuer, SerialNumber identifies the signing certificate, SubjectKeyID contains the key identifier (SecureBlackbox uses SHA-1 hash algorithm output as key identifiers). Finally, ValidationResult specifies whether signature is valid or not:

TimestampFound Event (XAdESVerifier Component)

Signifies the start of a timestamp validation routine.

Syntax

• C#
• VB.NET

public event OnTimestampFoundHandler OnTimestampFound;

public delegate void OnTimestampFoundHandler(object sender, XadesverifierTimestampFoundEventArgs e);

public class XadesverifierTimestampFoundEventArgs : EventArgs {
  public int Index { get; }
  public string IssuerRDN { get; }
  public byte[] SerialNumber { get; }
  public byte[] SubjectKeyID { get; }
  public bool CertFound { get; }
  public bool ValidateTimestamp { get; set; }
  public bool ValidateChain { get; set; }
}

Public Event OnTimestampFound As OnTimestampFoundHandler

Public Delegate Sub OnTimestampFoundHandler(sender As Object, e As XadesverifierTimestampFoundEventArgs)

Public Class XadesverifierTimestampFoundEventArgs Inherits EventArgs
  Public ReadOnly Property Index As Integer
  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 ValidateTimestamp As Boolean
  Public Property ValidateChain As Boolean
End Class

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 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 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 SignatureValidationResult and ChainValidationResult properties respectively.

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

TimestampValidated Event (XAdESVerifier Component)

Reports the completion of the timestamp validation routine.

Syntax

• C#
• VB.NET

public event OnTimestampValidatedHandler OnTimestampValidated;

public delegate void OnTimestampValidatedHandler(object sender, XadesverifierTimestampValidatedEventArgs e);

public class XadesverifierTimestampValidatedEventArgs : EventArgs {
  public int Index { get; }
  public string IssuerRDN { get; }
  public byte[] SerialNumber { get; }
  public byte[] SubjectKeyID { get; }
  public string Time { get; }

Public Class XadesverifierTLSCertNeededEventArgs 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 (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 (XAdESVerifier Component)

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

Syntax

• C#
• VB.NET

public event OnTLSCertValidateHandler OnTLSCertValidate;

public delegate void OnTLSCertValidateHandler(object sender, XadesverifierTLSCertValidateEventArgs e);

public class XadesverifierTLSCertValidateEventArgs : EventArgs {

Public Class XadesverifierTLSCertValidateEventArgs 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 TLSServerChain property to access the certificate chain. In general case, components may contact a number of TLS endpoints during their work, depending on their configuration.

Accept is assigned in accordance with the outcome of the internal validation check performed by the component, and can be adjusted if needed.

TLSEstablished Event (XAdESVerifier Component)

Fires when a TLS handshake with Host successfully completes.

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

TLSHandshake Event (XAdESVerifier Component)

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

Syntax

• C#
• VB.NET

public event OnTLSHandshakeHandler OnTLSHandshake;

public delegate void OnTLSHandshakeHandler(object sender, XadesverifierTLSHandshakeEventArgs e);
