# XMLVerifier Class

The XMLVerifier class provides simplified XML signature validation capabilities.

## Syntax

```text
secureblackbox.XMLVerifier
```

## Remarks

Use this control to validate XML-SIG signatures. XMLVerifier is capable of validating the integrity of the references covered by the signature and the integrity of the signature itself, using the certificate contained in the signature or provided from the user' code.

Note that this component only validates the cryptographic aspects of the signatures, but does not perform any chain of trust validation. As such, it is the task of your code to ensure that the signing certificate is good for its purpose and is trusted in your environment.

If you are looking to validate certificate trust in addition to the cryptographic capabilities, please consider using [XAdESVerifier](XAdESVerifier.md#XAdESVerifier). XAdESVerifier provides full support for advanced signature ecosystem, including revocation and Trusted List checking, timing checks, and chain of trust validation.

```

## 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 class manually.

The purpose of the certificates to be added to this collection is roughly equivalent to that of the Intermediate Certification Authorities system store in Windows.

Do not add trust anchors or root certificates to this collection: add them to TrustedCertificates instead.

This property is not available at design time.

 Please refer to the [Certificate](#certificate-type) type for a complete list of fields.

# Config Method ([XMLVerifier](#xmlverifier-class) Class)

Sets or retrieves a configuration setting.

## Syntax

```text
public String config(String configurationString);
```

## Remarks

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

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

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

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

# DoAction Method ([XMLVerifier](#xmlverifier-class) Class)

Performs an additional action.

## Syntax

```text
public String doAction(String actionID, String actionParams);
```

## Remarks

DoAction is a generic method available in every class. It is used to perform an additional action introduced after the product major release. The list of actions is not fixed, and may be flexibly extended over time.

The unique identifier (case insensitive) of the action is provided in the *ActionID* parameter.

*ActionParams* contains the value of a single parameter, or a list of multiple parameters for the action in the form of *PARAM1=VALUE1;PARAM2=VALUE2;...*.

Common ActionIDs:

|  |  |  |  |
| --- | --- | --- | --- |
| Action | Parameters | Returned value | Description |
| ResetTrustedListCache | none | none | Clears the cached list of trusted lists. |
| ResetCertificateCache | none | none | Clears the cached certificates. |

# DocumentLoaded Event ([XMLVerifier](#xmlverifier-class) Class)

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

## Syntax

```text
public class DefaultXMLVerifierEventListener implements XMLVerifierEventListener {
  ...
  public void documentLoaded(XMLVerifierDocumentLoadedEvent e) {}
  ...
}

public class XMLVerifierDocumentLoadedEvent {
  public boolean cancel; //read-write
}
```

## Remarks

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

# Error Event ([XMLVerifier](#xmlverifier-class) Class)

Information about errors during signature verification.

## Syntax

```text
public class DefaultXMLVerifierEventListener implements XMLVerifierEventListener {
  ...
  public void error(XMLVerifierErrorEvent e) {}
  ...
}

public class XMLVerifierErrorEvent {
  public int errorCode;
  public String description;
}
```

## Remarks

# Notification Event ([XMLVerifier](#xmlverifier-class) Class)

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

## Syntax

```text
public class DefaultXMLVerifierEventListener implements XMLVerifierEventListener {
  ...
  public void notification(XMLVerifierNotificationEvent e) {}
  ...
}

public class XMLVerifierNotificationEvent {
  public String eventID;
  public String eventParam;
}
```

## Remarks

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

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

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

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

# ReferenceValidated Event ([XMLVerifier](#xmlverifier-class) Class)

Marks the end of a reference validation.

## Syntax

```text
public class DefaultXMLVerifierEventListener implements XMLVerifierEventListener {
  ...
  public void referenceValidated(XMLVerifierReferenceValidatedEvent e) {}
  ...
}

public class XMLVerifierReferenceValidatedEvent {
  public int referenceIndex;
  public String ID;
  public String URI;
  public String refType;
  public boolean digestValid;
}
```

## Remarks

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

# ResolveReference Event ([XMLVerifier](#xmlverifier-class) Class)

Asks the application to resolve a reference.

## Syntax

```text
public class DefaultXMLVerifierEventListener implements XMLVerifierEventListener {
  ...
  public void resolveReference(XMLVerifierResolveReferenceEvent e) {}
  ...
}

public class XMLVerifierResolveReferenceEvent {
  public int referenceIndex;
  public String URI;
}
```

## Remarks

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

*URI* contains a reference to the data.

*ReferenceIndex* specifies the index of the reference to process.

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

# SignatureFound Event ([XMLVerifier](#xmlverifier-class) Class)

Signifies the start of signature validation.

## Syntax

```text
public class DefaultXMLVerifierEventListener implements XMLVerifierEventListener {
  ...
  public void signatureFound(XMLVerifierSignatureFoundEvent e) {}
  ...
}

public class XMLVerifierSignatureFoundEvent {
  public int index;
  public String entityLabel;
  public String issuerRDN;
  public byte[] serialNumber;
  public byte[] subjectKeyID;
  public boolean certFound;
  public boolean validateSignature; //read-write
  public boolean validateChain; //read-write
}
```

## Remarks

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

The *CertFound* parameter is set to True if the class has found the needed certificate in one of the known locations, and to False otherwise, in which case you must provide it manually via the [KnownCertificates](#knowncertificates-property-xmlverifier-class) property.

Signature validation consists of two independent stages: cryptographic signature validation and chain validation. Separate validation results are reported for each, with the [SignatureValidationResult](#PDFSignature_f_SignatureValidationResult) and [ChainValidationResult](#PDFSignature_f_ChainValidationResult) properties respectively.

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

# SignatureValidated Event ([XMLVerifier](#xmlverifier-class) Class)

Marks the completion of the signature validation routine.

## Syntax

```text
public class DefaultXMLVerifierEventListener implements XMLVerifierEventListener {
  ...
  public void signatureValidated(XMLVerifierSignatureValidatedEvent e) {}
  ...
}

public class XMLVerifierSignatureValidatedEvent {
  public int index;
  public String entityLabel;
  public String issuerRDN;
  public byte[] serialNumber;
  public byte[] subjectKeyID;
  public int validationResult;
  public boolean cancel; //read-write
}
```

## Remarks

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

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

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

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

## Fields

 **Bytes** *byte[] (read-only)*
*Default Value: ""*

Returns the raw certificate data in DER format.

 **CA** *boolean*
*Default Value: False*

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

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

 **CAKeyID** *byte[] (read-only)*
*Default Value: ""*

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

Authority Key Identifier is a certificate extension which allows identification of certificates belonging to the same issuer, but with different public keys. It is a de-facto standard to include this extension in all certificates to facilitate chain building.

This setting cannot be set when generating a certificate as it always derives from another certificate property. [CertificateManager](CertificateManager.md#CertificateManager) generates this setting automatically if enough information is available to it: for self-signed certificates, this value is copied from the [SubjectKeyID](#Certificate_f_SubjectKeyID) setting, and for lower-level certificates, from the parent certificate's subject key ID extension.

 **CertType** *int (read-only)*
*Default Value: 0*

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

A [Certificate](#certificate-type) 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.md#CertificateManager) class to load or create new certificate and certificate requests objects.

 **CRLDistributionPoints** *String*
*Default Value: ""*

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

Use this 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 Value: ""*

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

 **Fingerprint** *String (read-only)*
*Default Value: ""*

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

While there is no formal standard defining what a fingerprint is, a SHA1 hash of the certificate's DER-encoded body is typically used.

 **FriendlyName** *String (read-only)*
*Default Value: ""*

Contains an associated alias (friendly name) of the certificate. The friendly name is not a property of a certificate: it is maintained by the certificate media rather than being included in its DER representation. Windows certificate stores are one example of media that does support friendly names.

 **HashAlgorithm** *String*
*Default Value: ""*

Provides means to set the hash algorithm to be used in the subsequent operation on the certificate (such as generation or key signing). It is not a property of a certificate; use [SigAlgorithm](#Certificate_f_SigAlgorithm) to find out the hash algorithm that is part of the certificate signature.

Use the [KeyBits](#Certificate_f_KeyBits), [Curve](#Certificate_f_Curve), and [PublicKeyBytes](#Certificate_f_PublicKeyBytes) fields to get more details about the key the certificate contains.

 **KeyBits** *int (read-only)*
*Default Value: 0*

Returns the length of the public key in bits.

This value indicates the length of the principal cryptographic parameter of the key, such as the length of the RSA modulus or ECDSA field. The key data returned by the [PublicKeyBytes](#Certificate_f_PublicKeyBytes) or [PrivateKeyBytes](#Certificate_f_PrivateKeyBytes) field would typically contain auxiliary values, and therefore be longer.

 **KeyFingerprint** *String (read-only)*
*Default Value: ""*

Returns a SHA1 fingerprint of the public key contained in the certificate.

Note that the key fingerprint is different from the certificate fingerprint accessible via the [Fingerprint](#Certificate_f_Fingerprint) field. The key fingerprint uniquely identifies the public key, and so can be the same for multiple certificates containing the same key.

 **KeyUsage** *int*
*Default Value: 0*

Indicates the purposes of the key contained in the certificate, in the form of an OR'ed flag set.

This value is a bit mask of the following values:

|  |  |  |
| --- | --- | --- |
| ckuUnknown | 0x00000 | Unknown key usage |
| ckuDigitalSignature | 0x00001 | Digital signature |
| ckuNonRepudiation | 0x00002 | Non-repudiation |
| ckuKeyEncipherment | 0x00004 | Key encipherment |
| ckuDataEncipherment | 0x00008 | Data encipherment |
| ckuKeyAgreement | 0x00010 | Key agreement |
| ckuKeyCertSign | 0x00020 | Certificate signing |
| ckuCRLSign | 0x00040 | Revocation signing |
| ckuEncipherOnly | 0x00080 | Encipher only |
| ckuDecipherOnly | 0x00100 | Decipher only |
| ckuServerAuthentication | 0x00200 | Server authentication |
| ckuClientAuthentication | 0x00400 | Client authentication |
| ckuCodeSigning | 0x00800 | Code signing |
| ckuEmailProtection | 0x01000 | Email protection |
| ckuTimeStamping | 0x02000 | Timestamping |
| ckuOCSPSigning | 0x04000 | OCSP signing |
| ckuSmartCardLogon | 0x08000 | Smartcard logon |
| ckuKeyPurposeClientAuth | 0x10000 | Kerberos - client authentication |
| ckuKeyPurposeKDC | 0x20000 | Kerberos - KDC |

Set this field before generating the certificate to propagate the key usage flags to the new certificate.

 **KeyValid** *boolean (read-only)*
*Default Value: False*

Returns *True* if the certificate's key is cryptographically valid, and *False* otherwise.

 **OCSPLocations** *String*
*Default Value: ""*

Locations of OCSP services that can be used to check this certificate's validity in real time, as recorded by the CA.

Set this field before calling the certificate manager's [Generate](CertificateManager.md#CertificateManager_m_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** *boolean*
*Default Value: False*

Accessor to the value of the certificate's ocsp-no-check extension.

 **Origin** *int (read-only)*
*Default Value: 0*

Returns the location that the certificate was taken or loaded from.

 **PolicyIDs** *String*
*Default Value: ""*

Contains identifiers (OIDs) of the applicable certificate policies.

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

Set this 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 Value: ""*

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** *boolean (read-only)*
*Default Value: False*

Indicates whether the certificate has a usable private key associated with it. If it is set to *True*, the certificate can be used for private key operations, such as signing or decryption.

This field is independent from [PrivateKeyBytes](#Certificate_f_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** *boolean (read-only)*
*Default Value: False*

Indicates whether the private key is extractable (exportable).

 **PublicKeyBytes** *byte[] (read-only)*
*Default Value: ""*

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** *boolean (read-only)*
*Default Value: False*

Indicates whether the certificate is qualified.

This property is set to *True* if the certificate is confirmed by a Trusted List to be qualified.

 **QualifiedStatements** *int*
*Default Value: 0*

Returns a simplified qualified status of the certificate.

 **Qualifiers** *String (read-only)*
*Default Value: ""*

A list of qualifiers.

Contains a comma-separated list of qualifier aliases for the certificate, for example *QCP-n-qscd,QCWithSSCD*.

 **SelfSigned** *boolean (read-only)*
*Default Value: False*

Indicates whether the certificate is self-signed (root) or signed by an external CA.

 **SerialNumber** *byte[]*
*Default Value: ""*

Returns the certificate's serial number.

The serial number is a binary string that uniquely identifies a certificate among others issued by the same CA. According to the X.509 standard, the (issuer, serial number) pair should be globally unique to facilitate chain building.

 **SigAlgorithm** *String (read-only)*
*Default Value: ""*

Indicates the algorithm that was used by the CA to sign this certificate.

A signature algorithm typically combines hash and public key algorithms together, such as *sha256WithRSAEncryption* or *ecdsa-with-SHA256*.

 **Source** *int (read-only)*
*Default Value: 0*

Returns the source (location or disposition) of a cryptographic primitive entity, such as a certificate, CRL, or OCSP response.

 **Subject** *String (read-only)*
*Default Value: ""*

The common name of the certificate holder, typically an individual's name, a URL, an e-mail address, or a company name. This is part of a larger set of credentials available via [SubjectRDN](#Certificate_f_SubjectRDN).

 **SubjectAlternativeName** *String*
*Default Value: ""*

Returns or sets the value of the Subject Alternative Name extension of the certificate.

Subject alternative names are used to provide additional names that are impractical to store in the main [SubjectRDN](#Certificate_f_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 Value: ""*

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

Subject Key Identifier is a certificate extension which allows a specific public key to be associated with a certificate holder. Typically, subject key identifiers of CA certificates are recorded as respective CA key identifiers in the subordinate certificates that they issue, which facilitates chain building.

The [SubjectKeyID](#Certificate_f_SubjectKeyID) and [CAKeyID](#Certificate_f_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 Value: ""*

A list of *Property=Value* pairs that uniquely identify the certificate holder (subject).

Depending on the purpose of the certificate and the policies of the CA that issued it, the values included in the subject record may differ drastically and contain business or personal names, web URLs, email addresses, and other data.

Example: */C=US/O=Oranges and Apples, Inc./OU=Accounts Receivable/1.2.3.4.5=Value with unknown OID/CN=Margaret Watkins*.

 **Valid** *boolean (read-only)*
*Default Value: False*

Indicates whether or not the signature over the certificate or the request is valid and matches the public key contained in the CA certificate/request.

 **ValidFrom** *String*
*Default Value: ""*

The time point at which the certificate becomes valid, in UTC.

 **ValidTo** *String*
*Default Value: ""*

The time point at which the certificate expires, in UTC.

# Config Settings ([XMLVerifier](#xmlverifier-class) Class)

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

### XMLVerifier Config Settings

**AddAllDataObjectsTimestamp**: Whether to add all data objects timestamp during signing.If this property is set to True, the all data objects timestamp (xades:AllDataObjectsTimeStamp element) will be added.

**AsyncDocumentID**: Specifies the document ID for SignAsyncEnd() call.Use this property when working with multi-signature DCAuth requests and responses to uniquely identify documents signed within a larger batch. This value helps ASiCSigner identify the correct signature in the returned batch of responses. If using batched requests, make sure to set this property to the same value on both pre-signing (SignAsyncBegin) and completion (SignAsyncEnd) stages.

**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 1 day (86400 seconds). A value of 0 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 50 percent. Values are interpreted in the 0..100 range. A value of 0 disables the CRL ratio check. 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 10 minutes (600 seconds). A value of 0 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 1 hour (3600 seconds). A value of 0 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 50 percent. Values are interpreted in the 0..100 range. Open-ended OCSP responses without NextUpdate ignore this setting; use [CachedOCSPResponseMaxAge](#CachedOCSPResponseMaxAge) to limit their age. A value of 0 disables the OCSP response ratio check. 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 10 minutes (600 seconds). A value of 0 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.

**DataType**: Specifies the external data type.Use this property to specify the type of the external data (either [DataFile](#datafile-property-xmlverifier-class), [DataStream](#datastream-property-xmlverifier-class) or [DataBytes](#databytes-property-xmlverifier-class) properties) for class.

The following data types are supported:

|  |  |  |
| --- | --- | --- |
| "" or "XML" |  | an XML document (by default). |
| "data" |  | a binary data. |

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

The default value is **dcrlpPreferComplete** (1).

Supported values:

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

**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).

**ForceCompleteChainValidation**: Whether to check the CA certificates when the signing certificate is invalid.Set this property to True to check issuer (CA) certificates if the signing or an intermediate chain certificate is invalid.

**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.

**GracePeriod**: Specifies a grace period to apply during revocation information checks.Use this property to specify a grace period (in seconds). Grace period applies to certain subprotocols, such as OCSP, and caters to the inaccuracy and/or missynchronization of clocks on different participating systems. Any time deviations within the grace period will be tolerated.

**HMACKey**: The key value for HMAC.Use this property to set the HMAC key. The component uses base16 (hex) encoding for this configuration value.

**HMACOutputLength**: Sets the length of the HMAC output.Use this property to configure the length of the HMAC output, in bytes.

**HMACSigningUsed**: Whether to use HMAC signing.Set this property to true to make the component perform signing using HMAC method, rather than asymmetric cryptography. TBD

**IDAttributeName**: Specifies the custom name of ID attribute.This property contains the custom name of identifier (ID) attribute. Used to identify the target XML element when reference URI has "#id_name" value or when ID attribute should be auto-generated for a target XML element.

**IDAttributeNamespaceURI**: Specifies the custom namespace URI of ID attribute.This property contains the custom namespace URI of identifier (ID) attribute. Used to identify the target XML element when reference URI has "#id_name" value or when ID attribute should be auto-generated for a target XML element.

**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.

**IgnoreChainValidationErrors**: Whether to ignore any certificate chain validation issues.Enable this property to ignore any chain validation errors when creating a signature. This may be useful if the signature is created in an environment which uses different trust settings to the validation environment.

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

**IgnoreSystemTrust**: Whether trusted Windows Certificate Stores should be treated as trusted.Specifies whether, during chain validation, the class should respect the trust to CA certificates as configured in the operating system. In Windows this effectively defines whether the class should trust the certificates residing in the Trusted Root Certification Authorities store.

If [IgnoreSystemTrust](#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.

**IgnoreTimestampFailure**: Whether to ignore time-stamping failure during signing.If this property is set to True, any failure during time-stamping process will be ignored.

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

**IncludeKey**: Specifies whether to include the signing key to the signature.Set this property to True to include the public part of the signing key to the signature.

**IncludeKeyValue**: Specifies whether the key value must be included to the signature.Set this property to True if the key value (its public part) should be included to the signature.

**IncludeKnownRevocationInfoToSignature**: Whether to include custom revocation info to the signature.This property specifies whether revocation pieces provided via KnownCertificates, KnownCRLs, and KnownOCSPs properties should be included into the signature. This property lets you include custom validation elements to the signature in addition to the ones comprising the signing chain.

"ns1" prefix should be defined via [AddKnownNamespace](#addknownnamespace-method-xmlverifier-class) method. |
| Node name | indicates an XML element selected using its NodeName. For example: "data" - indicates an XML element with node name "data". |

**KeyInfoCustomXML**: The custom XML content for KeyInfo element.Use this property to specify the custom XML content of the ds:KeyInfo element.

| crl |  | Base64-encoded certificate revocation list (CRL) is placed to the signature |

**KeyInfoID**: Specifies the ID for KeyInfo element.This property contains the identifier (ID) attribute of the ds:KeyInfo element.

**KeyName**: Contains information about the key used for signing.The KeyName element contains a string value (with significant whitespaces) which may be used by the signer to communicate a key identifier to the recipient. Typically, the KeyName element contains an identifier related to the key pair used to sign the message, but it may contain other protocol-related information that indirectly identifies a key pair. Common uses of the KeyName include simple string names for keys, a key index, a distinguished name (DN), an email address, etc.

Supported values are case-insensitive:

|  |  |
| --- | --- |
| Default | Applies the AdES default freshness settings: crl:86400;50;600,ocsp:3600;50;600. This means: CRL maximum age 1 day, CRL age ratio 50%, CRL overlap 10 minutes; OCSP response maximum age 1 hour, OCSP response age ratio 50%, OCSP response overlap 10 minutes. This value is the default. |
| Disabled | Sets [CachedCRLOverlapTime](#CachedCRLOverlapTime), [CachedOCSPResponseOverlapTime](#CachedOCSPResponseOverlapTime), [CachedCRLMaxAge](#CachedCRLMaxAge), [CachedOCSPResponseMaxAge](#CachedOCSPResponseMaxAge), [CachedCRLMaxAgeRatio](#CachedCRLMaxAgeRatio), and [CachedOCSPResponseMaxAgeRatio](#CachedOCSPResponseMaxAgeRatio) to 0. It only disables the cache-age freshness policy; it does not disable revocation checking or use of the revocation cache. |
| 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.

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

**UseValidatorSettingsForTLSValidation**: Whether to employ the primary chain validator setup for auxiliary TLS chain validations.Use this property to specify whether you would like to use the primary (AdES) chain validator component to validate TLS chains for any connections involved (OCSP, CRL).

If *StaticDNS* of the class is set to "*local*", the property returns/restores the rules from/to the internal storage of the class. If *StaticDNS* of the class 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 classes.

**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).

**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.

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:

```

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).
