The CertificateValidator component provides fine-grained validation of X.509 certificates.

Syntax

nsoftware.SecureBlackbox.CertificateValidator

Remarks

This is a powerful and configurable component which can be used to validate all kinds of certificates and their chains.

The purpose of CertificateValidator is to validate certificate chains according to the X.509 specification. It supports a variety of technologies, including CRL and OCSP services, and can provide a comprehensive output on the certificate cryptographic validity, chain integrity, and trust levels. CertificateValidator is used internally in many other SecureBlackbox components, such as PDFSigner, HTTPClient, and OfficeVerifier.

To validate a certificate, please tune up the component as following:

Depending on the complexity of the chain and the configuration of the component, the validation routine may take certain amount of time. The validator reports chain validation progress using a selection of events, such as BeforeCertificateProcessing, AfterCertificateProcessing, and CRLDownloaded events. It may also ask you for missing objects using CRLNeeded or CACertificateNeeded events. In each such event handler you can access the currently validated certificate via the CurrentCertificate property, and the interim validity figures via the InterimValidationResult and InterimValidationDetails property.

The return of the Validate (or similar) method indicates the completion of the validation procedure. The outcome of the chain validation is represented with the two parameters:

  • ChainValidationResult reports the general validation outcome: valid, valid-but-untrusted, invalid, and unknown. As a rule, only the valid result can be taken as a good reason to consider the chain valid.
  • ChainValidationDetails provides insights into the factors that caused the validation to fail.
Apart from these two parameters, you can check the low-level validation details by consulting the ValidationLog property. The validation log is often a great source for tracking and reacting to various validation issues.

Note 1: On Windows, CertificateValidator can use CA and ROOT system stores to look for any missing CA certificates and trust anchors. No similar functionality is currently available for other platforms, so in most cases you must provide your own list of trusted and CA certificates via TrustedCertificates and KnownCertificates collections to have your chains validate fully in Linux and macOS projects.

Note 2: The OfflineMode property is a handy way to check the completeness of your revocation/validation information. When the offline mode is on, CertificateValidator won't go online for any missing certificates, CRLs, and OCSP responses. Paired with a switched-off UseSystemCertificates property, it allows to make sure that any content provided via KnownCertificates, KnownCRLs, and KnownOCSPs represents the complete set of validation information required to validate the chain.

Additional certificates for chain validation.

Syntax

public CertificateList KnownCertificates { get; }
Public Property KnownCertificates As CertificateList

Remarks

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 component 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.

This property is not available at design time.

Please refer to the Certificate type for a complete list of fields.

KnownCRLs Property (CertificateValidator Component)

Additional CRLs for chain validation.

Syntax

public CRLList KnownCRLs { get; }
Public Property KnownCRLs As CRLList

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.

This property is not available at design time.

Please refer to the CRL type for a complete list of fields.

KnownOCSPs Property (CertificateValidator Component)

Additional OCSP responses for chain validation.

Syntax

public OCSPResponseList KnownOCSPs { get; }
Public Property KnownOCSPs As OCSPResponseList

Remarks

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

This property is not available at design time.

Please refer to the OCSPResponse type for a complete list of fields.

MaxValidationTime Property (CertificateValidator Component)

Specifies the maximum time the validation process may take.

Syntax

public int MaxValidationTime { get; set; }
Public Property MaxValidationTime As Integer

Default Value

0

Remarks

Use this property to limit the amount of time available for the validator to carry out the validation. If the validation process exceeds this time, it is terminated and the validation error is returned.

OfflineMode Property (CertificateValidator Component)

Switches the component to offline mode.

Syntax

public bool OfflineMode { get; set; }
Public Property OfflineMode As Boolean

Default Value

False

Remarks

When working in offline mode, the component 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.

Proxy Property (CertificateValidator 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.

Please refer to the ProxySettings type for a complete list of fields.

QualifiedInfo Property (CertificateValidator Component)

The qualified details for the validated certificate.

Syntax

public QualifiedInfo QualifiedInfo { get; }
Public ReadOnly Property QualifiedInfo As QualifiedInfo

Remarks

Use this property to check the qualified information for Certificate. The contents of this property is updated upon completion of the full validation routine performed by the Validate method (if the qualified check is enabled) or after the GetQualifiedStatus call.

This property is read-only.

Please refer to the QualifiedInfo type for a complete list of fields.

RevocationCheck Property (CertificateValidator Component)

Specifies the kind(s) of revocation check to perform for all chain certificates.

Syntax

public CertificateValidatorRevocationChecks RevocationCheck { get; set; }

enum CertificateValidatorRevocationChecks { crcNone, crcAuto, crcAllCRL, crcAllOCSP, crcAllCRLAndOCSP, crcAnyCRL, crcAnyOCSP, crcAnyCRLOrOCSP, crcAnyOCSPOrCRL }
Public Property RevocationCheck As CertificatevalidatorRevocationChecks

Enum CertificateValidatorRevocationChecks 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.

crcNone0No revocation checking.
crcAuto1Automatic mode selection. Currently this maps to crcAnyOCSPOrCRL, but it may change in the future.
crcAllCRL2All provided CRL endpoints will be checked, and all checks must succeed.
crcAllOCSP3All provided OCSP endpoints will be checked, and all checks must succeed.
crcAllCRLAndOCSP4All provided CRL and OCSP endpoints will be checked, and all checks must succeed.
crcAnyCRL5All provided CRL endpoints will be checked, and at least one check must succeed.
crcAnyOCSP6All provided OCSP endpoints will be checked, and at least one check must succeed.
crcAnyCRLOrOCSP7All provided CRL and OCSP endpoints will be checked, and at least one check must succeed. CRL endpoints are checked first.
crcAnyOCSPOrCRL8All 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.

SocketSettings Property (CertificateValidator Component)

Manages network connection settings.

TrustedCertificates Property (CertificateValidator 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.

Sets or retrieves a configuration setting.

Syntax

public string Config(string configurationString);
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.

Validate Method (CertificateValidator Component)

Validates the certificate chain.

Syntax

public int Validate();
Public Function Validate() As Integer

Remarks

Use this method to validate the certificate chain that starts with Certificate.

The chain validation is a multi-step process which includes validation of each certificate in the chain up to the trusted anchor. The ultimate goal of this process is to establish the integrity of the chain and its trustworthiness.

Depending on the component tuneup, the validation process may differ drastically, even for the same certificate: it may be more or less rigorous, may include or exclude revocation checks, and may be more or less tolerant to minor chain issues.

When this process is completed, the final decision on the validity of the checked certificate is returned from this method, and also saved in ChainValidationResult property. Another property, ChainValidationDetails, provides insight into the reasons that contributed to that decision. Use ValidationLog to get a detailed step-by-step log of the entire validation process.

ValidateForSMIME Method (CertificateValidator Component)

Validates an e-mail signing certificate.

Syntax

public int ValidateForSMIME(string emailAddress);
Public Function ValidateForSMIME(ByVal EmailAddress As String) As Integer

This is a variant of Validate method that performs some additional e-mail specific checks, imposed by e-mail certificate rules. This method returns the overall chain validation result.

ValidateForSSL Method (CertificateValidator Component)

Validates a server-side SSL/TLS certificate.

Syntax

public int ValidateForSSL(string URL, string IPAddress);
Public Function ValidateForSSL(ByVal URL As String, ByVal IPAddress As String) As Integer

Remarks

Use this method to validate a server-side SSL/TLS certificate.

This is a variant of Validate method that performs some additional TLS-specific checks. It is important that you provide a correct URL or IPAddress for the check to return a reasonable and justified result.

This method returns the overall result of the chain validation.

AfterCertificateProcessing Event (CertificateValidator Component)

Marks the end of a single certificate processing step.

Syntax

public event OnAfterCertificateProcessingHandler OnAfterCertificateProcessing;

public delegate void OnAfterCertificateProcessingHandler(object sender, CertificateValidatorAfterCertificateProcessingEventArgs e);

public class CertificateValidatorAfterCertificateProcessingEventArgs : EventArgs {
  public string Cert { get; }
  public int Validity { get; }
  public int ValidationDetails { get; }
}
Public Event OnAfterCertificateProcessing As OnAfterCertificateProcessingHandler

Public Delegate Sub OnAfterCertificateProcessingHandler(sender As Object, e As CertificateValidatorAfterCertificateProcessingEventArgs)

Public Class CertificateValidatorAfterCertificateProcessingEventArgs Inherits EventArgs
  Public ReadOnly Property Cert As String
  Public ReadOnly Property Validity As Integer
  Public ReadOnly Property ValidationDetails As Integer
End Class

Remarks

This event is fired when the component has finished processing Cert, and returns its Validity status and ValidationDetails.

'Processing' consists of one or more 'validations' (with one CA certificate each), completion of each of which is reported via AfterCertificateValidation events. If a certificate is signed by a single CA (which is a typical case), processing is synonymous to validation.

You can influence the validation process by altering the provided validation outcome, such as changing the invalid status to valid. This can be done via InterimValidationResult and InterimValidationDetails properties.

Validity status:

cvtValid0The chain is valid

cvtValidButUntrusted1The chain is valid, but the root certificate is not trusted

cvtInvalid2The chain is not valid (some of certificates are revoked, expired, or contain an invalid signature)

cvtCantBeEstablished3The validity of the chain cannot be established because of missing or unavailable validation information (certificates, CRLs, or OCSP responses)

Validation details:

cvrBadData0x0001One or more certificates in the validation path are malformed

cvrRevoked0x0002One or more certificates are revoked

cvrNotYetValid0x0004One or more certificates are not yet valid

cvrExpired0x0008One or more certificates are expired

cvrInvalidSignature0x0010A certificate contains a non-valid digital signature

cvrUnknownCA0x0020A CA certificate for one or more certificates has not been found (chain incomplete)

cvrCAUnauthorized0x0040One of the CA certificates are not authorized to act as CA

cvrCRLNotVerified0x0080One or more CRLs could not be verified

cvrOCSPNotVerified0x0100One or more OCSP responses could not be verified

cvrIdentityMismatch0x0200The identity protected by the certificate (a TLS endpoint or an e-mail addressee) does not match what is recorded in the certificate

cvrNoKeyUsage0x0400A mandatory key usage is not enabled in one of the chain certificates

cvrBlocked0x0800One or more certificates are blocked

cvrFailure0x1000General validation failure

cvrChainLoop0x2000Chain loop: one of the CA certificates recursively signs itself

cvrWeakAlgorithm0x4000A weak algorithm is used in one of certificates or revocation elements

cvrUserEnforced0x8000The chain was considered invalid following intervention from a user code

public event OnAfterCertificateValidationHandler OnAfterCertificateValidation;

public delegate void OnAfterCertificateValidationHandler(object sender, CertificateValidatorAfterCertificateValidationEventArgs e);

public class CertificateValidatorAfterCertificateValidationEventArgs : EventArgs {
  public string Cert { get; }
  public string CACert { get; }
  public int Validity { get; }
  public int ValidationDetails { get; }
}
Public Event OnAfterCertificateValidation As OnAfterCertificateValidationHandler

Public Delegate Sub OnAfterCertificateValidationHandler(sender As Object, e As CertificateValidatorAfterCertificateValidationEventArgs)

Public Class CertificateValidatorAfterCertificateValidationEventArgs Inherits EventArgs
  Public ReadOnly Property Cert As String
  Public ReadOnly Property CACert As String
  Public ReadOnly Property Validity As Integer
  Public ReadOnly Property ValidationDetails As Integer
End Class

Remarks

This event is fired when the component has finished validation of Cert with CACert, and returns its Validity status and ValidationDetails.

'Validation', in this context, means a single validation of a certificate with its CA certificate. For certificates with multiple CAs, validations are grouped into 'processings.' Each processing, therefore, is a set of validations of the same certificate with all its CAs.

You can influence the validation process by altering the provided validation outcome, such as changing the invalid status to valid. This can be done via InterimValidationResult and InterimValidationDetails properties.

Validity status:

cvtValid0The chain is valid

cvtValidButUntrusted1The chain is valid, but the root certificate is not trusted

cvtInvalid2The chain is not valid (some of certificates are revoked, expired, or contain an invalid signature)

cvtCantBeEstablished3The validity of the chain cannot be established because of missing or unavailable validation information (certificates, CRLs, or OCSP responses)

Validation details:

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:

DownloadTSLThis event is fired if a Trusted List is requested. The EventParam parameter contains the URL value from where to retrieve the TrustedList. The downloaded Trusted List content should be assigned to the TSLContent or TSLContentHex configuration settings. The component automatically downloads Trusted List if OfflineMode is disabled and no Trusted List content is provided. It is important to note that if you are caching the Trusted List content, you should check the NextUpdate field of the Trusted List and update it in a timely manner, otherwise the outdated Trusted List will be discarded.
StoreTSLThis event is fired if the Trusted List should be stored for offline usage. The EventParam parameter contains the URL value from where the Trusted List was retrieved. The TrustedList content could be read using TSLContent or TSLContentHex configuration settings.

OCSPDownloaded Event (CertificateValidator Component)

Marks the success of an OCSP request.

Syntax

public event OnOCSPDownloadedHandler OnOCSPDownloaded;

public delegate void OnOCSPDownloadedHandler(object sender, CertificateValidatorOCSPDownloadedEventArgs e);

public class CertificateValidatorOCSPDownloadedEventArgs : EventArgs {
  public string Cert { get; }
  public string CACert { get; }
  public string Location { get; }
}
Public Event OnOCSPDownloaded As OnOCSPDownloadedHandler

Public Delegate Sub OnOCSPDownloadedHandler(sender As Object, e As CertificateValidatorOCSPDownloadedEventArgs)

Public Class CertificateValidatorOCSPDownloadedEventArgs Inherits EventArgs
  Public ReadOnly Property Cert As String
  Public ReadOnly Property CACert As String
  Public ReadOnly Property Location As String
End Class

Remarks

This event is fired when an OCSP response containing the validation information for Cert has been successfully downloaded from Location. This event is always preceded with BeforeOCSPDownload event.

TLSCertNeeded Event (CertificateValidator Component)

Fires when a remote TLS party requests a client certificate.

Syntax

public event OnTLSCertNeededHandler OnTLSCertNeeded;

public delegate void OnTLSCertNeededHandler(object sender, CertificateValidatorTLSCertNeededEventArgs e);

public class CertificateValidatorTLSCertNeededEventArgs : EventArgs {
  public string Host { get; }
  public string CANames { get; }
}
Public Event OnTLSCertNeeded As OnTLSCertNeededHandler

Public Delegate Sub OnTLSCertNeededHandler(sender As Object, e As CertificateValidatorTLSCertNeededEventArgs)

Public Class CertificateValidatorTLSCertNeededEventArgs 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 (CertificateValidator 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, CertificateValidatorTLSCertValidateEventArgs e);

public class CertificateValidatorTLSCertValidateEventArgs : 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 CertificateValidatorTLSCertValidateEventArgs)

Public Class CertificateValidatorTLSCertValidateEventArgs 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 (CertificateValidator Component)

Fires when a TLS handshake with Host successfully completes.

Syntax

public event OnTLSEstablishedHandler OnTLSEstablished;

public delegate void OnTLSEstablishedHandler(object sender, CertificateValidatorTLSEstablishedEventArgs e);

public class CertificateValidatorTLSEstablishedEventArgs : 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 CertificateValidatorTLSEstablishedEventArgs)

Public Class CertificateValidatorTLSEstablishedEventArgs 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 (CertificateValidator Component)

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

Syntax

public event OnTLSHandshakeHandler OnTLSHandshake;

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

public class CertificateValidatorTLSHandshakeEventArgs : EventArgs {
  public string Host { get; }
  public bool Abort { get; set; }
}
Public Event OnTLSHandshake As OnTLSHandshakeHandler

Public Delegate Sub OnTLSHandshakeHandler(sender As Object, e As CertificateValidatorTLSHandshakeEventArgs)

Public Class CertificateValidatorTLSHandshakeEventArgs 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 (CertificateValidator Component)

Reports the graceful closure of a TLS connection.

Syntax

public event OnTLSShutdownHandler OnTLSShutdown;

public delegate void OnTLSShutdownHandler(object sender, CertificateValidatorTLSShutdownEventArgs e);

public class CertificateValidatorTLSShutdownEventArgs : EventArgs {
  public string Host { get; }
}
Public Event OnTLSShutdown As OnTLSShutdownHandler

Public Delegate Sub OnTLSShutdownHandler(sender As Object, e As CertificateValidatorTLSShutdownEventArgs)

Public Class CertificateValidatorTLSShutdownEventArgs 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.

The following fields are available:

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:

ckuUnknown0x00000Unknown key usage

ckuDigitalSignature0x00001Digital signature

ckuNonRepudiation0x00002Non-repudiation

ckuKeyEncipherment0x00004Key encipherment

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.

RenegotiationAttackPreventionMode
RenegotiationAttackPreventionModes

Default: 2

Selects the renegotiation attack prevention mechanism.

The following options are available:

crapmCompatible0TLS 1.0 and 1.1 compatibility mode (renegotiation indication extension is disabled).
crapmStrict1Renegotiation attack prevention is enabled and enforced.
crapmAuto2Automatically 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.

crcNone0No revocation checking.
crcAuto1Automatic mode selection. Currently this maps to crcAnyOCSPOrCRL, but it may change in the future.
crcAllCRL2All provided CRL endpoints will be checked, and all checks must succeed.
crcAllOCSP3All provided OCSP endpoints will be checked, and all checks must succeed.
crcAllCRLAndOCSP4All provided CRL and OCSP endpoints will be checked, and all checks must succeed.
crcAnyCRL5All provided CRL endpoints will be checked, and at least one check must succeed.
crcAnyOCSP6All provided OCSP endpoints will be checked, and at least one check must succeed.
crcAnyCRLOrOCSP7All provided CRL and OCSP endpoints will be checked, and at least one check must succeed. CRL endpoints are checked first.
crcAnyOCSPOrCRL8All 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.

Config Settings (CertificateValidator Component)

The component 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 component, access to these internal properties is provided through the Config method.

CertificateValidator Config Settings

CacheValidityTime:   Time period during which to keep validation cache.

The validity period of the cached validation results in milliseconds.

CheckStrongAlgorithmForTrusted:   Whether to check a 'strong' hash algorithm for trusted certificates.

Whether to check a 'strong' hash algorithm for trusted certificates.

CheckValidityPeriodForTrusted:   Whether to check validity period for trusted certificates.

Whether to check validity period for trusted certificates.

CrossCertificationValidationStrategy:   Defines how the cross certification validation is performed.

This property tells the component how to perform the cross certification validation. Supported values: csvSmart = 0 csvOptimistic = 1 csvPessimistic = 2 csvNoCrossCertification = 3

In the optimistic strategy, positive validation results are kept, and negative ones are ignored. If there are no good certificates in the chain, the validation proceeds using self-signed certificates. Smart is the same as optimistic.

In the pessimistic strategy, even one negative validation result makes the whole process to fail.

DislikeOpenEndedOCSPs:   Tells the component 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 component 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).

ForceCompleteChainValidationForTrusted:   Whether to continue with the full validation up to the root CA certificate for mid-level trust anchors.

Set this property to True to enable full chain validation for explicitly trusted intermediary or end-entity certificates. This may be useful when creating signatures to enforce completeness of the collected revocation information. It often makes sense to set this property to false when validating signatures to reduce validation time and avoid issues with badly configured environments.

ForceRevocationCheckForRoot:   Whether to check revocation info for root certificates.

Specifies if revocation information should be checked for the root certificate.

IgnoreBadOCSPChains:   Whether to ignore bad OCSP chains during validation.

Whether to ignore bad OCSP chains during validation.

IgnoreCABasicConstraints:   Whether to ignore the Basic Constraints extension for the CA certificates.

Whether to ignore the Basic Constraints extension for the CA certificates.

IgnoreCAKeyUsage:   Whether to ignore Key Usage extension for CA certificates.

Whether to ignore Key Usage extension for CA certificates.

IgnoreCANameConstraints:   Whether to ignore the Name Constraints extension for the CA certificates.

Whether to ignore the Name Constraints extension for the CA certificates.

IgnoreChainLoops:   Whether chain loops should be ignored.

Set this property to True to make the validation engine ignore chain loops. This may be an option when you need to process chains from buggy CAs that happen to include subchains that sign themselves.

IgnoreCRLIssuerKeyID:   Tells the validator to ignore malformed CRL issuer key IDs.

Another compatibility/tolerance tweak that tells the validator to ignore the issuer key identifier values recorded in the processed CRLs (occasionally it is recorded there wrongly).

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.

IgnoreRevocationKeyUsage:   Whether to check the CA certs used to sign revocation info.

Whether the issuer (CA) certificates should be checked if their key usage extension (when available) allows using them to sign revocation information.

IgnoreSSLKeyUsage:   Whether to check the CA certs used in SSL/TLS.

Whether the issuer (CA) certificates should be checked if their key usage extension (when available) allows using these certificates in SSL protocol communications.

IgnoreSystemTrust:   Whether trusted Windows Certificate Stores should be treated as trusted.

Specifies whether, during chain validation, the component should respect the trust to CA certificates as configured in the operating system. In Windows this effectively defines whether the component should trust the certificates residing in the Trusted Root Certification Authorities store.

If IgnoreSystemTrust is True, certificates residing in the trusted root store are treated as if they are known, rather than trusted. Only certificates provided via other means (such as the TrustedCertificates property) are considered trusted.

ImplicitlyTrustSelfSignedCertificates:   Whether to trust self-signed certificates.

Set this property to True to implicitly trust all self-signed certificates.

LookupCRLByNameIfDPNotPresent:   Whether to look for implicit CRL Distribution Points.

Whether to look for implicit CRL Distribution Points (DPs) if no DPs are available.

PromoteLongOCSPResponses:   Whether long OCSP responses are requested.

Set this property to True to force the component to publish 'long' form of OCSP responses. Otherwise, only BasicOCSPResponse blobs are promoted.

RevocationMomentGracePeriod:   Grace period for revocation information propagation.

Use this property to specify the grace period (in seconds). Grace period allows the certificate revocation information to propagate through the revocation process.

SkipSubjectNameIfAltNameExists:   Whether to check CommonName if SubjectAltName is present.

RFC 6125 requires that the SubjectAltName (SAN) extension should be checked if it is present. In such case, SubjectName.CommonName (CN) should not be checked. This contradicts to some existing certificates where, for instance, CN contains "a.com" and SAN is "www.a.com".

UseMicrosoftCTL:   Enables or disables the automatic use of the Microsoft online certificate trust list.

Enable this property to make the chain validation module automatically look up missing CA certificates in the public Windows Update repository.

UseValidationCache:   Enables or disable the use of the product-wide certificate chain validation cache.

Use this property to enable or disable the use of the global chain validation cache. If enabled, the component will consult the product-wide validation cache when validating the signing chains. Also, the outcomes of any new chain validations performed by the component, both interim and final, will be saved in the cache and available for re-use by any future validations. Disable this property to ignore the cache and always perform the validation from a fresh start.

ValidateInvalidCertificates:   Whether to do all checks on invalid certificates.

If ValidateInvalidCertificates is True and certain certificate check determines that the certificate is not valid, further checks are done anyway. This allows to create a full validation report.

When ValidateInvalidCertificates is False and a certificate is found to be not valid, further checks of this certificate are not performed.

WeakAlgorithmHandlingMode:   How to handle certificates signed with a 'weak' hash algorithm.

Defines how to handle the certificates signed using a 'weak' hash algorithm.

Supported values: wahmIgnore = 0 wahmWarning = 1 wahmError = 2
