# CertificateValidator Component

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

## Syntax

```text
secureblackbox.CertificateValidator
```

## Remarks

This is a powerful and configurable struct 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:

- Assign the certificate to be validated to the Certificate property.
- Set [RevocationCheck](#revocationcheck-property-certificatevalidator-component) in accordance with your revocation check preferences.
- Enable [UseSystemCertificates](#usesystemcertificates-property-certificatevalidator-component) property to trust certificates that are trusted by the operating system. Copy any certificates that are not available in the standard system locations to KnownCertificates and TrustedCertificates collections (see Note 1 below).
- Optionally, adjust TLSSettings and SocketSettings.
- Adjust [ValidationMoment](#validationmoment-property-certificatevalidator-component) if you would like to check the certificate validity at a different moment in time. Leave it unchanged to validate the certificate at the current time moment.
- Call [Validate](#validate-method-certificatevalidator-component) or [ValidateForSSL](#validateforssl-method-certificatevalidator-component) method to initiate chain validation.

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](#beforecertificateprocessing-event-certificatevalidator-component), [AfterCertificateProcessing](#aftercertificateprocessing-event-certificatevalidator-component), and [CRLDownloaded](#crldownloaded-event-certificatevalidator-component) events. It may also ask you for missing objects using [CRLNeeded](#crlneeded-event-certificatevalidator-component) or [CACertificateNeeded](#cacertificateneeded-event-certificatevalidator-component) 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](#interimvalidationresult-property-certificatevalidator-component) and [InterimValidationDetails](#interimvalidationdetails-property-certificatevalidator-component) property.

The return of the [Validate](#validate-method-certificatevalidator-component) (or similar) method indicates the completion of the validation procedure. The outcome of the chain validation is represented with the two parameters:

- [ChainValidationResult](#chainvalidationresult-property-certificatevalidator-component) 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](#chainvalidationdetails-property-certificatevalidator-component) 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](#validationlog-property-certificatevalidator-component) 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](#offlinemode-property-certificatevalidator-component) 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](#usesystemcertificates-property-certificatevalidator-component) 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.

## Syntax

*Go Syntax*

```text
func (obj *CertificateValidator) CurrentCACertCAKeyID() ([]byte, error)
```

## Remarks

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](#CertificateManager) generates this setting automatically if enough information is available to it: for self-signed certificates, this value is copied from the [CurrentCACertSubjectKeyID](#currentcacertsubjectkeyid-property-certificatevalidator-component) setting, and for lower-level certificates, from the parent certificate's subject key ID extension.

This property is read-only.

## Data Type

**[]byte**

# CurrentCACertCertType Property ([CertificateValidator](#certificatevalidator-component) Component)

Returns the type of the entity contained in the Certificate object.

## Syntax

*Go Syntax*

```text
func (obj *CertificateValidator) CurrentCACertCertType() (int32, error)
```

## Possible Values

```text
0   // Unknown1   // X509Certificate2   // X509CertificateRequest
```

## Default Value

0

## Remarks

Returns the type of the entity contained in the [Certificate](#Type_Certificate) object.

A [Certificate](#Type_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](#CertificateManager) struct to load or create new certificate and certificate requests objects.

This property is read-only.

## Data Type

**int32**

# CurrentCACertCRLDistributionPoints Property ([CertificateValidator](#certificatevalidator-component) Component)

Contains a list of locations of CRL distribution points used to check this certificate's validity.

## Syntax

*Go Syntax*

```text
func (obj *CertificateValidator) CurrentCACertCRLDistributionPoints() (string, error)
```

## Default Value

""

## Remarks

Contains a list of locations of CRL distribution points used to check this certificate's validity. The list is taken from the respective certificate extension.

Use this property when generating a certificate to provide a list of CRL endpoints that should be made part of the new certificate.

The endpoints are provided as a list of CRLF-separated URLs. Note that this differs from the behaviour used in earlier product versions, where the "|" character was used as the location separator.

This property is read-only.

## Data Type

**string**

# CurrentCACertCurve Property ([CertificateValidator](#certificatevalidator-component) Component)

Specifies the elliptic curve associated with the certificate's public key.

## Syntax

*Go Syntax*

The Certificate Policies extension identifies a sequence of policies under which the certificate has been issued, and which regulate its usage.

Set this property when generating a certificate to propagate the policies information to the new certificate.

The policies are provided as a list of CRLF-separated entries. Note that this differs from the behaviour used in earlier product versions, where the "|" character was used as the policy element separator.

This property is read-only.

## Data Type

**string**

# CurrentCACertPrivateKeyBytes Property ([CertificateValidator](#certificatevalidator-component) Component)

Returns the certificate's private key in DER-encoded format.

## Syntax

*Go Syntax*

```text
func (obj *CertificateValidator) CurrentCACertPrivateKeyBytes() ([]byte, error)
```

Subject alternative names are used to provide additional names that are impractical to store in the main [CurrentCACertSubjectRDN](#currentcacertsubjectrdn-property-certificatevalidator-component) 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.

This property is read-only.

## Data Type

**string**

# CurrentCACertSubjectKeyID Property ([CertificateValidator](#certificatevalidator-component) Component)

Contains a unique identifier of the certificate's cryptographic key.

## Syntax

*Go Syntax*

```text
func (obj *CertificateValidator) CurrentCACertSubjectKeyID() ([]byte, error)
```

## Remarks

func (obj *CertificateValidator) CurrentCertCA() (bool, error)
```

## Default Value

false

## Remarks

Indicates whether the certificate has a CA capability. For the certificate to be considered a CA, it must have its Basic Constraints extension set with the CA indicator enabled.

Set this property when generating a new certificate to have its Basic Constraints extension generated automatically.

This property is read-only.

## Data Type

**bool**

# CurrentCertCAKeyID Property ([CertificateValidator](#certificatevalidator-component) Component)

A unique identifier (fingerprint) of the CA certificate's cryptographic key.

## Syntax

*Go Syntax*

```text
func (obj *CertificateValidator) CurrentCertCAKeyID() ([]byte, error)
```

## Remarks

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](#CertificateManager) generates this setting automatically if enough information is available to it: for self-signed certificates, this value is copied from the [CurrentCertSubjectKeyID](#currentcertsubjectkeyid-property-certificatevalidator-component) setting, and for lower-level certificates, from the parent certificate's subject key ID extension.

This property is read-only.

## Data Type

**[]byte**

# CurrentCertCertType Property ([CertificateValidator](#certificatevalidator-component) Component)

Returns the type of the entity contained in the Certificate object.

## Syntax

*Go Syntax*

```text
func (obj *CertificateValidator) CurrentCertCertType() (int32, error)
```

## Possible Values

```text
0   // Unknown1   // X509Certificate2   // X509CertificateRequest
```

## Default Value

0

## Remarks

Returns the type of the entity contained in the [Certificate](#Type_Certificate) object.

A [Certificate](#Type_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](#CertificateManager) struct to load or create new certificate and certificate requests objects.

This property is read-only.

## Data Type

**int32**

# CurrentCertCRLDistributionPoints Property ([CertificateValidator](#certificatevalidator-component) Component)

Contains a list of locations of CRL distribution points used to check this certificate's validity.

## Syntax

*Go Syntax*

```text
func (obj *CertificateValidator) CurrentCertCRLDistributionPoints() (string, error)
```

## Default Value

""

## Remarks

Contains a list of locations of CRL distribution points used to check this certificate's validity. The list is taken from the respective certificate extension.

Use this property when generating a certificate to provide a list of CRL endpoints that should be made part of the new certificate.

The endpoints are provided as a list of CRLF-separated URLs. Note that this differs from the behaviour used in earlier product versions, where the "|" character was used as the location separator.

This property is read-only.

## Data Type

**string**

# CurrentCertCurve Property ([CertificateValidator](#certificatevalidator-component) Component)

Specifies the elliptic curve associated with the certificate's public key.

## Syntax

*Go Syntax*

```text
func (obj *CertificateValidator) CurrentCertCurve() (string, error)
```

## Default Value

""

## Remarks

Specifies the elliptic curve associated with the certificate's public key. This setting only applies to certificates containing EC keys.

## Data Type

**string**

# CurrentCertFingerprint Property ([CertificateValidator](#certificatevalidator-component) Component)

Contains the fingerprint (a hash imprint) of this certificate.

## Syntax

*Go Syntax*

```text
func (obj *CertificateValidator) CurrentCertFingerprint() (string, error)
```

## Default Value

""

## Remarks

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.

This property is read-only.

## Data Type

**string**

# CurrentCertFriendlyName Property ([CertificateValidator](#certificatevalidator-component) Component)

Contains an associated alias (friendly name) of the certificate.

## Syntax

*Go Syntax*

```text
func (obj *CertificateValidator) CurrentCertFriendlyName() (string, error)
```

## Default Value

""

## Remarks

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.

This property is read-only.

## Data Type

**string**

# CurrentCertHandle Property ([CertificateValidator](#certificatevalidator-component) Component)

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

## Syntax

*Go Syntax*

```text
func (obj *CertificateValidator) CurrentCertHandle() (int64, error)
```

## Default Value

0

## Remarks

Allows to get or set a 'handle', a unique identifier of the underlying property object. Use this property to assign objects of the same type in a quicker manner, without copying them fieldwise.

When you pass a handle of one object to another, the source object is copied to the destination rather than assigned. It is safe to get rid of the original object after such operation.

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

This property is read-only.

## Data Type

**int64**

# CurrentCertHashAlgorithm Property ([CertificateValidator](#certificatevalidator-component) Component)

Provides means to set the hash algorithm to be used in the subsequent operation on the certificate (such as generation or key signing).

## Syntax

*Go Syntax*

```text
func (obj *CertificateValidator) CurrentCertHashAlgorithm() (string, error)
```

## Default Value

""

## Remarks

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 [CurrentCertSigAlgorithm](#currentcertsigalgorithm-property-certificatevalidator-component) to find out the hash algorithm that is part of the certificate signature.

```

## 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.

## Data Type

**int32**

# TLSServerCertBytes Property ([CertificateValidator](#certificatevalidator-component) Component)

Returns the raw certificate data in DER format.

## Syntax

*Go Syntax*

```text
func (obj *CertificateValidator) TLSServerCertBytes(TLSServerCertIndex int32) ([]byte, error)
```

## Remarks

Returns the raw certificate data in DER format.

The *TLSServerCertIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [TLSServerCertCount](#tlsservercertcount-property-certificatevalidator-component) property.

This property is read-only.

## Data Type

**[]byte**

# TLSServerCertFingerprint Property ([CertificateValidator](#certificatevalidator-component) Component)

Contains the fingerprint (a hash imprint) of this certificate.

## Syntax

*Go Syntax*

```text
func (obj *CertificateValidator) TLSServerCertFingerprint(TLSServerCertIndex int32) (string, error)
```

## Default Value

""

## Remarks

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.

The *TLSServerCertIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [TLSServerCertCount](#tlsservercertcount-property-certificatevalidator-component) property.

This property is read-only.

## Data Type

**string**

# TLSServerCertHandle Property ([CertificateValidator](#certificatevalidator-component) Component)

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

## Syntax

*Go Syntax*

```text
func (obj *CertificateValidator) TLSServerCertHandle(TLSServerCertIndex int32) (int64, error)
```

## Default Value

0

## Remarks

Allows to get or set a 'handle', a unique identifier of the underlying property object. Use this property to assign objects of the same type in a quicker manner, without copying them fieldwise.

When you pass a handle of one object to another, the source object is copied to the destination rather than assigned. It is safe to get rid of the original object after such operation.

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

# TLSRevocationCheck Property ([CertificateValidator](#certificatevalidator-component) Component)

Specifies the kind(s) of revocation check to perform.

## Syntax

```

## Default Value

1

## Remarks

Specifies the kind(s) of revocation check to perform.

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

|  |  |  |
| --- | --- | --- |
| crcNone | 0 | No revocation checking. |
| crcAuto | 1 | Automatic mode selection. Currently this maps to crcAnyOCSPOrCRL, but it may change in the future. |
| 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.

## Data Type

**int32**

# UsedCertBytes Property ([CertificateValidator](#certificatevalidator-component) Component)

Returns the raw certificate data in DER format.

## Syntax

*Go Syntax*

```text
func (obj *CertificateValidator) UsedCertBytes(UsedCertIndex int32) ([]byte, error)
```

## Remarks

Returns the raw certificate data in DER format.

The *UsedCertIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [UsedCertCount](#usedcertcount-property-certificatevalidator-component) property.

This property is read-only.

## Data Type

**[]byte**

# UsedCertCA Property ([CertificateValidator](#certificatevalidator-component) Component)

Indicates whether the certificate has a CA capability.

## Syntax

*Go Syntax*

```text
func (obj *CertificateValidator) UsedCertCA(UsedCertIndex int32) (bool, error)
```

## Default Value

false

## Remarks

Indicates whether the certificate has a CA capability. For the certificate to be considered a CA, it must have its Basic Constraints extension set with the CA indicator enabled.

Set this property when generating a new certificate to have its Basic Constraints extension generated automatically.

The *UsedCertIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [UsedCertCount](#usedcertcount-property-certificatevalidator-component) property.

This property is read-only.

## Data Type

**bool**

# UsedCertCAKeyID Property ([CertificateValidator](#certificatevalidator-component) Component)

A unique identifier (fingerprint) of the CA certificate's cryptographic key.

## Syntax

*Go Syntax*

```text
func (obj *CertificateValidator) UsedCertCAKeyID(UsedCertIndex int32) ([]byte, error)
```

## Remarks

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](#CertificateManager) generates this setting automatically if enough information is available to it: for self-signed certificates, this value is copied from the [UsedCertSubjectKeyID](#usedcertsubjectkeyid-property-certificatevalidator-component) setting, and for lower-level certificates, from the parent certificate's subject key ID extension.

The *UsedCertIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [UsedCertCount](#usedcertcount-property-certificatevalidator-component) property.

This property is read-only.

## Data Type

**[]byte**

# UsedCertCertType Property ([CertificateValidator](#certificatevalidator-component) Component)

Returns the type of the entity contained in the Certificate object.

## Syntax

*Go Syntax*

```text
func (obj *CertificateValidator) UsedCertCertType(UsedCertIndex int32) (int32, error)
```

## Possible Values

```text
0   // Unknown1   // X509Certificate2   // X509CertificateRequest
```

## Default Value

0

## Remarks

Returns the type of the entity contained in the [Certificate](#Type_Certificate) object.

A [Certificate](#Type_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](#CertificateManager) struct to load or create new certificate and certificate requests objects.

The *UsedCertIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [UsedCertCount](#usedcertcount-property-certificatevalidator-component) property.

This property is read-only.

## Data Type

**int32**

# UsedCertCRLDistributionPoints Property ([CertificateValidator](#certificatevalidator-component) Component)

Contains a list of locations of CRL distribution points used to check this certificate's validity.

## Syntax

*Go Syntax*

```text
func (obj *CertificateValidator) UsedCertCRLDistributionPoints(UsedCertIndex int32) (string, error)
```

## Default Value

""

## Remarks

Contains a list of locations of CRL distribution points used to check this certificate's validity. The list is taken from the respective certificate extension.

Use this property when generating a certificate to provide a list of CRL endpoints that should be made part of the new certificate.

The endpoints are provided as a list of CRLF-separated URLs. Note that this differs from the behaviour used in earlier product versions, where the "|" character was used as the location separator.

The *UsedCertIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [UsedCertCount](#usedcertcount-property-certificatevalidator-component) property.

This property is read-only.

## Data Type

**string**

# UsedCertCurve Property ([CertificateValidator](#certificatevalidator-component) Component)

Specifies the elliptic curve associated with the certificate's public key.

## Syntax

*Go Syntax*

```text
func (obj *CertificateValidator) UsedCertCurve(UsedCertIndex int32) (string, error)
```

## Default Value

""

## Remarks

Specifies the elliptic curve associated with the certificate's public key. This setting only applies to certificates containing EC keys.

## Remarks

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

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the struct, access to these *internal properties* is provided through the Config method.

To set a configuration setting named *PROPERTY*, you must call *Config("PROPERTY=VALUE")*, where *VALUE* is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a [configuration setting](#config-settings-certificatevalidator-component), you must call *Config("PROPERTY")*. The value will be returned as a string.

# Validate Method ([CertificateValidator](#certificatevalidator-component) Component)

Validates the certificate chain.

## Syntax

*Go Syntax*

```text
func (obj *CertificateValidator) Validate() (int32, error)
```

## 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](#chainvalidationresult-property-certificatevalidator-component) property. Another property, [ChainValidationDetails](#chainvalidationdetails-property-certificatevalidator-component), provides insight into the reasons that contributed to that decision. Use [ValidationLog](#validationlog-property-certificatevalidator-component) to get a detailed step-by-step log of the entire validation process.

# ValidateForSMIME Method ([CertificateValidator](#certificatevalidator-component) Component)

Validates an e-mail signing certificate.

## Syntax

*Go Syntax*

# ValidateForSSL Method ([CertificateValidator](#certificatevalidator-component) Component)

Validates a server-side SSL/TLS certificate.

## Syntax

*Go Syntax*

```text
func (obj *CertificateValidator) ValidateForSSL(URL string, IPAddress string) (int32, error)
```

## Remarks

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

This is a variant of [Validate](#validate-method-certificatevalidator-component) 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](#certificatevalidator-component) Component)

Marks the end of a single certificate processing step.

## Syntax

*Go Syntax*

```text
// CertificateValidatorAfterCertificateProcessingEventArgs carries the CertificateValidator AfterCertificateProcessing event's parameters.
type CertificateValidatorAfterCertificateProcessingEventArgs struct {...}

func (args *CertificateValidatorAfterCertificateProcessingEventArgs) Cert() string
func (args *CertificateValidatorAfterCertificateProcessingEventArgs) Validity() int32
func (args *CertificateValidatorAfterCertificateProcessingEventArgs) ValidationDetails() int32
// CertificateValidatorAfterCertificateProcessingEvent defines the signature of the CertificateValidator AfterCertificateProcessing event's handler function.
type CertificateValidatorAfterCertificateProcessingEvent func(sender *CertificateValidator, args *CertificateValidatorAfterCertificateProcessingEventArgs)

func (obj *CertificateValidator) GetOnAfterCertificateProcessingHandler() CertificateValidatorAfterCertificateProcessingEvent
func (obj *CertificateValidator) SetOnAfterCertificateProcessingHandler(handlerFunc CertificateValidatorAfterCertificateProcessingEvent)
```

## Remarks

This event is fired when the struct 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](#aftercertificatevalidation-event-certificatevalidator-component) 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](#interimvalidationresult-property-certificatevalidator-component) and [InterimValidationDetails](#interimvalidationdetails-property-certificatevalidator-component) properties.

Validity status:

|  |  |  |
| --- | --- | --- |
| 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) |

Validation details:

|  |  |  |
| --- | --- | --- |
| cvrBadData | 0x0001 | One or more certificates in the validation path are malformed |
| cvrRevoked | 0x0002 | One or more certificates are revoked |
| cvrNotYetValid | 0x0004 | One or more certificates are not yet valid |
| cvrExpired | 0x0008 | One or more certificates are expired |
| cvrInvalidSignature | 0x0010 | A certificate contains a non-valid digital signature |
| cvrUnknownCA | 0x0020 | A CA certificate for one or more certificates has not been found (chain incomplete) |
| cvrCAUnauthorized | 0x0040 | One of the CA certificates are not authorized to act as CA |
| cvrCRLNotVerified | 0x0080 | One or more CRLs could not be verified |
| cvrOCSPNotVerified | 0x0100 | One or more OCSP responses could not be verified |
| cvrIdentityMismatch | 0x0200 | The identity protected by the certificate (a TLS endpoint or an e-mail addressee) does not match what is recorded in the certificate |
| cvrNoKeyUsage | 0x0400 | A mandatory key usage is not enabled in one of the chain certificates |
| cvrBlocked | 0x0800 | One or more certificates are blocked |
| cvrFailure | 0x1000 | General validation failure |
| cvrChainLoop | 0x2000 | Chain loop: one of the CA certificates recursively signs itself |
| cvrWeakAlgorithm | 0x4000 | A weak algorithm is used in one of certificates or revocation elements |
| cvrUserEnforced | 0x8000 | The chain was considered invalid following intervention from a user code |

# AfterCertificateValidation Event ([CertificateValidator](#certificatevalidator-component) Component)

Marks the end of a single certificate validation step.

## Syntax

*Go Syntax*

```text
// CertificateValidatorAfterCertificateValidationEventArgs carries the CertificateValidator AfterCertificateValidation event's parameters.
type CertificateValidatorAfterCertificateValidationEventArgs struct {...}

func (args *CertificateValidatorAfterCertificateValidationEventArgs) Cert() string
func (args *CertificateValidatorAfterCertificateValidationEventArgs) CACert() string
func (args *CertificateValidatorAfterCertificateValidationEventArgs) Validity() int32
func (args *CertificateValidatorAfterCertificateValidationEventArgs) ValidationDetails() int32
// CertificateValidatorAfterCertificateValidationEvent defines the signature of the CertificateValidator AfterCertificateValidation event's handler function.
type CertificateValidatorAfterCertificateValidationEvent func(sender *CertificateValidator, args *CertificateValidatorAfterCertificateValidationEventArgs)

func (obj *CertificateValidator) GetOnAfterCertificateValidationHandler() CertificateValidatorAfterCertificateValidationEvent
func (obj *CertificateValidator) SetOnAfterCertificateValidationHandler(handlerFunc CertificateValidatorAfterCertificateValidationEvent)
```

## Remarks

This event is fired when the struct 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](#interimvalidationresult-property-certificatevalidator-component) and [InterimValidationDetails](#interimvalidationdetails-property-certificatevalidator-component) properties.

Validity status:

|  |  |  |
| --- | --- | --- |
| 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) |

# BeforeCertificateProcessing Event ([CertificateValidator](#certificatevalidator-component) Component)

Reports the start of certificate processing.

## Syntax

*Go Syntax*

```text
// CertificateValidatorBeforeCertificateProcessingEventArgs carries the CertificateValidator BeforeCertificateProcessing event's parameters.
type CertificateValidatorBeforeCertificateProcessingEventArgs struct {...}

func (args *CertificateValidatorBeforeCertificateProcessingEventArgs) Cert() string
func (args *CertificateValidatorBeforeCertificateProcessingEventArgs) Validity() int32
func (args *CertificateValidatorBeforeCertificateProcessingEventArgs) ValidationDetails() int32
// CertificateValidatorBeforeCertificateProcessingEvent defines the signature of the CertificateValidator BeforeCertificateProcessing event's handler function.

func (obj *CertificateValidator) GetOnBeforeCertificateProcessingHandler() CertificateValidatorBeforeCertificateProcessingEvent
func (obj *CertificateValidator) SetOnBeforeCertificateProcessingHandler(handlerFunc CertificateValidatorBeforeCertificateProcessingEvent)
```

## Remarks

This event is fired when the struct is about to start the processing of *Cert*.

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

The firing of [AfterCertificateProcessing](#aftercertificateprocessing-event-certificatevalidator-component) marks the end of the certificate processing.

*Validity* and *ValidationDetails* specify the current validation status.

Validity status:

|  |  |  |
| --- | --- | --- |
| 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) |

Validation details:

|  |  |  |
| --- | --- | --- |
| cvrBadData | 0x0001 | One or more certificates in the validation path are malformed |

func (obj *CertificateValidator) SetOnNotificationHandler(handlerFunc CertificateValidatorNotificationEvent)
```

## Remarks

The struct fires this event to let the application know about some event, occurrence, or milestone in the struct. For example, it may fire to report completion of the document processing. The list of events being reported is not fixed, and may be flexibly extended over time.

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

This struct can fire this event with the following *EventID* values:

|  |  |
| --- | --- |
| DownloadTSL | This 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 struct automatically downloads Trusted List if [OfflineMode](#offlinemode-property-certificatevalidator-component) 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. |
| StoreTSL | This 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](#certificatevalidator-component) Component)

func (obj *CertificateValidator) GetOnOCSPDownloadedHandler() CertificateValidatorOCSPDownloadedEvent
func (obj *CertificateValidator) SetOnOCSPDownloadedHandler(handlerFunc CertificateValidatorOCSPDownloadedEvent)
```

## 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](#beforeocspdownload-event-certificatevalidator-component) event.

# TLSCertNeeded Event ([CertificateValidator](#certificatevalidator-component) Component)

Fires when a remote TLS party requests a client certificate.

## Syntax

*Go Syntax*

```text
// CertificateValidatorTLSCertNeededEventArgs carries the CertificateValidator TLSCertNeeded event's parameters.
type CertificateValidatorTLSCertNeededEventArgs struct {...}

func (args *CertificateValidatorTLSCertNeededEventArgs) Host() string
func (args *CertificateValidatorTLSCertNeededEventArgs) CANames() string
// CertificateValidatorTLSCertNeededEvent defines the signature of the CertificateValidator TLSCertNeeded event's handler function.

func (obj *CertificateValidator) GetOnTLSCertNeededHandler() CertificateValidatorTLSCertNeededEvent
func (obj *CertificateValidator) SetOnTLSCertNeededHandler(handlerFunc CertificateValidatorTLSCertNeededEvent)
```

## Remarks

This event fires to notify the implementation that a remote TLS server has requested a client certificate. The *Host* parameter identifies the host that makes a request, and the *CANames* parameter (optional, according to the TLS spec) advises on the accepted issuing CAs.

Use the TLSClientChain property in response to this event to provide the requested certificate. Please make sure the client certificate includes the associated private key. Note that you may set the certificates before the connection without waiting for this event to fire.

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

# TLSCertValidate Event ([CertificateValidator](#certificatevalidator-component) Component)

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

## Syntax

*Go Syntax*

```text
// CertificateValidatorTLSCertValidateEventArgs carries the CertificateValidator TLSCertValidate event's parameters.
type CertificateValidatorTLSCertValidateEventArgs struct {...}

func (args *CertificateValidatorTLSCertValidateEventArgs) ServerHost() string
func (args *CertificateValidatorTLSCertValidateEventArgs) ServerIP() string

func (obj *CertificateValidator) GetOnTLSShutdownHandler() CertificateValidatorTLSShutdownEvent
func (obj *CertificateValidator) SetOnTLSShutdownHandler(handlerFunc CertificateValidatorTLSShutdownEvent)
```

## Remarks

This event notifies the application about the closure of an earlier established TLS connection. Note that only graceful connection closures are reported.

# Config Settings ([CertificateValidator](#certificatevalidator-component) Component)

 The struct accepts one or more of the following *configuration settings*. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the struct, access to these *internal properties* is provided through the [Config](#config-method-certificatevalidator-component) method.

### CertificateValidator Config Settings

**CachedCRLMaxAge**: Specifies the maximum age of a cached CRL.Use this setting to specify the maximum number of seconds that may pass since a CRL was added to the global cache. When the cached CRL is older than this value, it is disregarded and a new CRL should be fetched.

The default value is 0, which disables the absolute CRL age check. See [RevocationCacheAgePolicy](#RevocationCacheAgePolicy) for configuring this setting together with the related cached revocation freshness settings.

**CachedCRLMaxAgeRatio**: Specifies the maximum age of a cached CRL as a percentage of its remaining lifetime.Use this setting to specify the percentage of the CRL's remaining lifetime, measured from the time the CRL was added to the global cache to the CRL's NextUpdate. When this portion of the remaining lifetime has passed, the cached CRL is disregarded and a new CRL should be fetched.

The default value is 0, which disables the CRL ratio check. Values are interpreted in the 0..100 range. See [RevocationCacheAgePolicy](#RevocationCacheAgePolicy) for configuring this setting together with the related cached revocation freshness settings.

**CachedCRLOverlapTime**: Specifies the time period before a cached CRL's NextUpdate when it is considered stale and must be refreshed.Use this setting to specify the number of seconds before the NextUpdate time at which the cached CRL should be disregarded, and a new CRL should be fetched.

The default value is 0, which disables the CRL overlap check. See [RevocationCacheAgePolicy](#RevocationCacheAgePolicy) for configuring this setting together with the related cached revocation freshness settings.

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

**CachedOCSPResponseMaxAge**: Specifies the maximum age of a cached OCSP response.Use this setting to specify the maximum number of seconds that may pass since an OCSP response was added to the global cache. When the cached OCSP response is older than this value, it is disregarded and a new OCSP response should be fetched.

The default value is 0, which disables the absolute OCSP response age check. This setting is also used to limit open-ended OCSP responses that do not have NextUpdate. See [RevocationCacheAgePolicy](#RevocationCacheAgePolicy) for configuring this setting together with the related cached revocation freshness settings.

**CachedOCSPResponseMaxAgeRatio**: Specifies the maximum age of a cached OCSP response as a percentage of its remaining lifetime.Use this setting to specify the percentage of the OCSP response's remaining lifetime, measured from the time the OCSP response was added to the global cache to the response's NextUpdate. When this portion of the remaining lifetime has passed, the cached OCSP response is disregarded and a new OCSP response should be fetched.

The default value is 0, which disables the OCSP response ratio check. Values are interpreted in the 0..100 range. Open-ended OCSP responses without NextUpdate ignore this setting; use [CachedOCSPResponseMaxAge](#CachedOCSPResponseMaxAge) to limit their age. See [RevocationCacheAgePolicy](#RevocationCacheAgePolicy) for configuring this setting together with the related cached revocation freshness settings.

**CachedOCSPResponseOverlapTime**: Specifies the time period before a cached OCSP response's NextUpdate when it is considered stale and must be refreshed.Use this setting to specify the number of seconds before the NextUpdate time at which the cached OCSP response should be disregarded, and a new OCSP response should be fetched.

The default value is 0, which disables the OCSP response overlap check. See [RevocationCacheAgePolicy](#RevocationCacheAgePolicy) for configuring this setting together with the related cached revocation freshness settings.

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

**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 struct 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.

**DeltaCRLPreference**: Specifies whether complete or delta CRLs are preferred.Use this setting to specify which CRL type should be preferred during revocation checks.

The default value is **dcrlpPreferDelta** (0).

Supported values:

- **dcrlpPreferDelta** (0): retrieve and use delta CRLs when available, falling back to complete CRLs when needed.
- **dcrlpPreferComplete** (1): try complete CRLs first, and use delta CRLs only if complete CRLs cannot be retrieved.

**DislikeOpenEndedOCSPs**: Tells the struct 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 struct 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).

**EvaluateSystemTrust**: Enables or disables usage of the platform's built-in trust validation facilities.When enabled, the component delegates the certificate chain validation to the operating system's native trust evaluation mechanism (e.g. SecTrustEvaluate on Apple platforms). This functionality is currently available on macOS and iOS systems only. This property is disabled by default, because enabling it may prevent the AdES components from collecting full revocation information required for long-term validation (LTV) signatures.

**EvaluateSystemTrustForSelfSignedCertificates**: Enables or disables usage of the platform's built-in trust validation facilities for self-signed certificates.When enabled, the component delegates the certificate chain validation to the operating system's native trust evaluation mechanism (e.g. SecTrustEvaluate on Apple platforms) for self-signed certificates. This functionality is currently available on macOS and iOS systems only. This property is enabled by default.

**EvaluateSystemTrustForSSL**: Enables or disables usage of the platform's built-in trust validation facilities for SSL/TLS.When enabled, the component delegates the certificate chain validation to the operating system's native trust evaluation mechanism (e.g. SecTrustEvaluate on Apple platforms) specifically for SSL/TLS certificates. This functionality is currently available on macOS and iOS systems only. This property is enabled by default.

**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.

**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 struct should respect the trust to CA certificates as configured in the operating system. In Windows this effectively defines whether the struct should trust the certificates residing in the Trusted Root Certification Authorities store.

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

**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 struct to publish 'long' form of OCSP responses. Otherwise, only BasicOCSPResponse blobs are promoted.

**RevocationCacheAgePolicy**: Specifies a preset policy for cached CRL and OCSP response freshness settings.Use this setting to configure all cached revocation freshness settings at once. The default value is Disabled.

Supported values are case-insensitive:

|  |  |
| --- | --- |
| Disabled | Sets [CachedCRLOverlapTime](#CachedCRLOverlapTime), [CachedOCSPResponseOverlapTime](#CachedOCSPResponseOverlapTime), [CachedCRLMaxAge](#CachedCRLMaxAge), [CachedOCSPResponseMaxAge](#CachedOCSPResponseMaxAge), [CachedCRLMaxAgeRatio](#CachedCRLMaxAgeRatio), and [CachedOCSPResponseMaxAgeRatio](#CachedOCSPResponseMaxAgeRatio) to 0. This value is the default. It only disables the cache-age freshness policy; it does not disable revocation checking or use of the revocation cache. |
| Default | Applies the component default freshness settings. For this component, Default is equivalent to Disabled. |
| Short | Uses crl:43200;50;300,ocsp:1800;50;300. This means: CRL maximum age 12 hours, CRL age ratio 50%, CRL overlap 5 minutes; OCSP response maximum age 30 minutes, OCSP response age ratio 50%, OCSP response overlap 5 minutes. |
| Long | Uses crl:518400;50;3600,ocsp:21600;50;3600. This means: CRL maximum age 6 days, CRL age ratio 50%, CRL overlap 1 hour; OCSP response maximum age 6 hours, OCSP response age ratio 50%, OCSP response overlap 1 hour. |
| N | Interprets N as an integer number of seconds. The overlap settings are set to N seconds, CRL maximum age is set to N * 144, OCSP response maximum age is set to N * 6, and both ratio settings are set to 50. |
| crl:<maxAge>;<ratio>;<overlap>,ocsp:<maxAge>;<ratio>;<overlap> | Sets the CRL and OCSP response freshness values explicitly. |

Ratios must be in the 0..100 range. Maximum age and overlap values must be non-negative. Short and Long are time-scale profiles: Long allows older cached revocation information by increasing maximum ages, but also uses a larger pre-expiry safety margin by increasing overlap times. For individual [CachedCRLOverlapTime](#CachedCRLOverlapTime), [CachedOCSPResponseOverlapTime](#CachedOCSPResponseOverlapTime), [CachedCRLMaxAge](#CachedCRLMaxAge), [CachedOCSPResponseMaxAge](#CachedOCSPResponseMaxAge), [CachedCRLMaxAgeRatio](#CachedCRLMaxAgeRatio), and [CachedOCSPResponseMaxAgeRatio](#CachedOCSPResponseMaxAgeRatio) settings, a value of 0 disables the corresponding freshness check. The individual settings remain available for advanced configuration and can be used after this setting to override specific values.

**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".

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

**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 struct will consult the product-wide validation cache when validating the signing chains. Also, the outcomes of any new chain validations performed by the struct, 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

### Base Config Settings

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

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

**CheckKeyIntegrityBeforeUse**: Enables or disable private key integrity check before use.This global property enables or disables private key material check before each signing operation. This slows down performance a bit, but prevents a selection of attacks on RSA keys where keys with unknown origins are used.

You can switch this property off to improve performance if your project only uses known, good private keys.

**CookieCaching**: Specifies whether a cookie cache should be used for HTTP(S) transports.Set this property to enable or disable cookies caching for the struct.

Supported values are:

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

**Cookies**: Gets or sets local cookies for the struct.Use this property to get cookies from the internal cookie storage of the struct and/or restore them back between application sessions.

**DefDeriveKeyIterations**: Specifies the default key derivation algorithm iteration count.This global property sets the default number of iterations for all supported key derivation algorithms. Note that you can provide the required number of iterations by using properties of the relevant key generation component; this global setting is used in scenarios where specific iteration count is not or cannot be provided.

Some OCSP responders can only use older algorithms, in which case setting this property to SHA1 may be helpful.

**OldClientSideRSAFallback**: Specifies whether the SSH client should use a SHA1 fallback.Tells the SSH client to use a legacy ssh-rsa authentication even if the server indicates support for newer algorithms, such as rsa-sha-256. This is a backward-compatibility tweak.

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

Supported Values:

|  |  |
| --- | --- |

```

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

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

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

Example:

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

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

**ProductVersion**: Returns the version of the SecureBlackbox library.This property returns the long version string of the SecureBlackbox library being used (major.minor.build.revision).

| --- | --- | --- |
| none |  | No static DNS rules (default) |
| local |  | Local static DNS rules |
| global |  | Global static DNS rules |

**StaticIPAddress[domain]**: Gets or sets an IP address for the specified domain name.Use this property to get or set an IP address for the specified domain name in the internal (of the struct) or global DNS rules storage depending on the *StaticDNS* value. The type of the IP address (IPv4 or IPv6) is determined automatically. If both addresses are available, they are divided by the | (pipe) character.

**StaticIPAddresses**: Gets or sets all the static DNS rules.Use this property to get static DNS rules from the current rules storage or restore them back between application sessions. If *StaticDNS* of the struct is set to "*local*", the property returns/restores the rules from/to the internal storage of the struct. If *StaticDNS* of the struct is set to "*global*", the property returns/restores the rules from/to the GLOBAL storage. The rules list is returned and accepted in JSON format.

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

**TLSSessionGroup**: Specifies the group name of TLS sessions to be used for session resumption.Use this property to limit the search of cached TLS sessions to the specified group. Sessions from other groups will be ignored. By default, all sessions are cached with an empty group name and available to all the structs.

**TLSSessionLifetime**: Specifies lifetime in seconds of the cached TLS session.Use this property to specify how much time the TLS session should be kept in the session cache. After this time, the session expires and will be automatically removed from the cache. Default value is 300 seconds (5 minutes).

**TLSSessionPurgeInterval**: Specifies how often the session cache should remove the expired TLS sessions.Use this property to specify the time interval of purging the expired TLS sessions from the session cache. Default value is 60 seconds (1 minute).

**UseCRLObjectCaching**: Specifies whether reuse of loaded CRL objects is enabled.This setting enables or disables the caching of CRL objects. When set to true (the default value), the system checks if a CRL object is already loaded in memory before attempting to load a new instance. If the object is found, the existing instance is reused, and its reference count is incremented to track its usage. When the reference count reaches zero, indicating that no references to the object remain, the system will free the object from memory. This setting enhances performance by minimizing unnecessary object instantiation and promotes efficient memory management, particularly in scenarios where CRL objects are frequently used.

**UseInternalRandom**: Switches between SecureBlackbox-own and platform PRNGs.Allows to switch between internal/native PRNG implementation and the one provided by the platform.

**UseLegacyAdESValidation**: Enables legacy AdES validation mode.Use this setting to switch the AdES component to the validation approach that was used in SBB 2020/SBB 2022 (less attention to temporal details).

**UseOCSPResponseObjectCaching**: Specifies whether reuse of loaded OCSP response objects is enabled.This setting enables or disables the caching of OCSP response objects. When set to true (the default value), the system checks if a OCSP response object is already loaded in memory before attempting to load a new instance. If the object is found, the existing instance is reused, and its reference count is incremented to track its usage. When the reference count reaches zero, indicating that no references to the object remain, the system will free the object from memory. This setting enhances performance by minimizing unnecessary object instantiation and promotes efficient memory management, particularly in scenarios where OCSP response objects are frequently used.

**UseOwnDNSResolver**: Specifies whether the client components should use own DNS resolver.Set this global property to false to force all the client components to use the DNS resolver provided by the target OS instead of using own one.

**UseSharedSystemStorages**: Specifies whether the validation engine should use a global per-process copy of the system certificate stores.Set this global property to false to make each validation run use its own copy of system certificate stores.

**UseSystemNativeSizeCalculation**: An internal CryptoAPI access tweak.This is an internal setting. Please do not use it unless instructed by the support team.

**UseSystemOAEPAndPSS**: Enforces or disables the use of system-driven RSA OAEP and PSS computations.This global setting defines who is responsible for performing RSA-OAEP and RSA-PSS computations where the private key is stored in a Windows system store and is exportable. If set to true, SBB will delegate the computations to Windows via a CryptoAPI call. Otherwise, it will export the key material and perform the computations using its own OAEP/PSS implementation.

This setting only applies to certificates originating from a Windows system store.

**UseSystemRandom**: Enables or disables the use of the OS PRNG.Use this global property to enable or disable the use of operating system-driven pseudorandom number generation.

**XMLRDNDescriptorName[OID]**: Defines an OID mapping to descriptor names for the certificate's IssuerRDN or SubjectRDN.This property defines custom mappings between Object Identifiers (OIDs) and descriptor names. This mapping specifies how the certificate's issuer and subject information (ds:IssuerRDN and ds:SubjectRDN elements respectively) are represented in XML signatures.

The property accepts comma-separated values where the first descriptor name is used when the OID is mapped, and subsequent values act as aliases for parsing.

Syntax:

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

Where:

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

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

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

Usage Examples:

Map OID 2.5.4.5 to SERIALNUMBER:

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

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

```text
Config("XMLRDNDescriptorName[1.2.840.113549.1.9.1]=E,EMAIL,EMAILADDRESS");
```

**XMLRDNDescriptorPriority[OID]**: Specifies the priority of descriptor names associated with a specific OID.This property specifies the priority of descriptor names associated with a specific OID that allows to reorder descriptors in the ds:IssuerRDN and ds:SubjectRDN elements during signing.

**XMLRDNDescriptorReverseOrder**: Specifies whether to reverse the order of descriptors in RDN.Specifies whether to reverse the order of descriptors in the ds:IssuerRDN and ds:SubjectRDN elements during XML signing. By default, this property is set to true (as specified in RFC 2253, 2.1).

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