# XAdESVerifier Class

The XAdESVerifier class verifies XAdES-compliant signatures and their trust chains.

## Syntax

```text
class secureblackbox.XAdESVerifier
```

## Remarks

XAdESVerifier validates electronic signatures that comply with the Electronic Signatures and Infrastructures (ESI) XML Advanced Electronic Signatures (XAdES) specification. XAdES builds on XML-SIG containers to add trust and long-term validity services to generic certificate-based XML signatures.

XAdES signatures are made over XML files, and support all the diversity offered by the underlying, more generic XML-SIG standard. The container options include enveloping signatures (with data being signed encapsulated into the outer XML signature), enveloped signatures (with signature being placed under the root of the outer signed document), and detached signatures (with the signed document distributed separately). It is important to find out what kind of signatures you are working with, as the validation process for detached signatures can be slightly different.

XAdESVerifier provides a simple and powerful mechanism to verify XAdES signatures in accordance with the respective [ETSI standards](https://ec.europa.eu/digital-building-blocks/sites/display/DIGITAL/Standards+and+specifications) (ETSI EN 319 132). It supports the following features of the standard (which cover the most of it):

- Enveloped, enveloping and detached signatures.
- Matching the signature to all the current and older ETSI signature profiles (including B-B, B-T, B-LT, B-LTA).
- Short-term, long-term, and archival signatures.
- RFC 3161 timestamps.
- Complete chain of trust validation process, using local, global, nation-specific (EUTL), or custom trust.
- Removal of existing signatures.
- Custom XML namespaces and tags.
- Online and offline modes.

The component is being actively maintained and updated, following ongoing developments in AdES world. For more than 10 years, our engineers have been active participants of ETSI Plugtests events, to make sure that our e-Signature infrastructure is compliant and highly interoperable.

Just like our other signature components, XAdESVerifier supports several work modes that differ in complexity, allowing for both 'quick' and 'flexible' use. The simple mode assumes providing the [input_file](#input_file-property) and the [output_file](#output_file-property), and calling the one-pass [verify](#verify-method) method (for detached signatures you will also need to provide the data being covered via the [data_file](#data_file-property) property and call [verify_detached](#verify_detached-method) instead). This approach is straightforward and would let you integrate XAdES verification in accordance with built-in validation defaults.

More complex tune-ups may involve fine-grained adjustment of validation properties, such as providing your own validation material (certificates, OCSPs, CRLs) or fine-tuning conflict/error resolution options. You can also choose to work with the container step-by-step, by splitting the one-pass operation into a sequence of individual [open](#open-method), validate/[revalidate](#revalidate-method), and [close](#close-method) calls. XAdESVerifier lets you walk up and down the XML signature tree to any level of depth using its powerful [select_info](#select_info-method) mechanism.

```text
XAdESVerifier verifier = new XAdESVerifier();

// Select the file which contains the signed message
verifier.setInputFile("signedFile.xml");
verifier.open();

if (verifier.getSignatures().item(0).getSignatureType() == XAdESSignature.cxstDetached){
  // To verify a detached signature, we need
  // to provide both the signature and the original data
  verifier.setDataFile("MyFile.xml");
  verifier.verifyDetached();
}
else {
  // To verify an enveloping signature, we need
  // to provide the location to extract the data
  verifier.setOutputFile("output.exe");
  verifier.verify();
}

// The outcome of the cryptographic signature validation
for (int idx = 0; idx < verifier.getSignatures().size() ; idx++) {
  switch (verifier.getSignatures().item(0).getSignatureValidationResult()) {
    case XAdESSignature.svtValid:
      System.out.println("The signature is valid.");
      break;
    case XAdESSignature.svtUnknown:
      System.out.println("Signature verification failed: Unknown signature.");
      break;
    case XAdESSignature.svtFailure:
    case XAdESSignature.svtCorrupted:
      System.out.println("Signature verification failed: The signature is corrupt or invalid.");
      break;
    case XAdESSignature.svtSignerNotFound:
      System.out.println("Signature verification failed: The signature does not contain a signer.");
      break;
    default:
      System.out.println("Signature verification failed.");
      break;
  }
}

- [blocked_cert_bytes](#blocked_cert_bytes-property)
- [blocked_cert_handle](#blocked_cert_handle-property)

The array indices start at *0* and end at *blocked_cert_count - 1*.

# blocked_cert_bytes property

Returns the raw certificate data in DER format.

## Syntax

```text
def get_blocked_cert_bytes(blocked_cert_index: int) -> bytes: ...
```

## Remarks

Returns the raw certificate data in DER format.

The *blocked_cert_index* parameter specifies the index of the item in the array. The size of the array is controlled by the [blocked_cert_count](#blocked_cert_count-property) property.

This property is read-only.

# blocked_cert_handle property

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

## Syntax

```text
def get_blocked_cert_handle(blocked_cert_index: int) -> int: ...
def set_blocked_cert_handle(blocked_cert_index: int, value: int) -> None: ...
```

## 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.

# cert_bytes property

Returns the raw certificate data in DER format.

## Syntax

```text
def get_cert_bytes(cert_index: int) -> bytes: ...
```

## Remarks

Returns the raw certificate data in DER format.

The *cert_index* parameter specifies the index of the item in the array. The size of the array is controlled by the [cert_count](#cert_count-property) property.

This property is read-only.

# cert_ca property

Indicates whether the certificate has a CA capability.

## Syntax

```text
def get_cert_ca(cert_index: int) -> bool: ...
```

## 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 *cert_index* parameter specifies the index of the item in the array. The size of the array is controlled by the [cert_count](#cert_count-property) property.

This property is read-only.

# cert_ca_key_id property

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

## Syntax

```text
def get_cert_ca_key_id(cert_index: int) -> bytes: ...
```

## 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 [cert_subject_key_id](#cert_subject_key_id-property) setting, and for lower-level certificates, from the parent certificate's subject key ID extension.

The *cert_index* parameter specifies the index of the item in the array. The size of the array is controlled by the [cert_count](#cert_count-property) property.

This property is read-only.

# cert_type property

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

## Syntax

```text
def get_cert_type(cert_index: int) -> int: ...
```

## 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) class to load or create new certificate and certificate requests objects.

The *cert_index* parameter specifies the index of the item in the array. The size of the array is controlled by the [cert_count](#cert_count-property) property.

This property is read-only.

# cert_crl_distribution_points property

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

## Syntax

```text
def get_cert_crl_distribution_points(cert_index: int) -> str: ...
```

## 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 *cert_index* parameter specifies the index of the item in the array. The size of the array is controlled by the [cert_count](#cert_count-property) property.

This property is read-only.

# cert_curve property

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

## Syntax

```text
def get_cert_curve(cert_index: int) -> str: ...
```

## Default Value

""

## Remarks

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

## Syntax

```text
def get_cert_subject_key_id(cert_index: int) -> bytes: ...
```

## Remarks

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 [cert_subject_key_id](#cert_subject_key_id-property) and [cert_ca_key_id](#cert_ca_key_id-property) properties of self-signed certificates typically contain identical values, as in that specific case, the issuer and the subject are the same entity.

```

## 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.

# tls_revocation_check property

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

## Syntax

```text
def get_tls_revocation_check() -> int: ...

```

## 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.

# config method

Sets or retrieves a configuration setting.

## Syntax

```text
def config(configuration_string: str) -> str: ...
```

## Remarks

config is a generic method available in every class. It is used to set and retrieve [configuration settings](#xadesverifier-config-settings) 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](#xadesverifier-config-settings), you must call *Config("PROPERTY")*. The value will be returned as a string.

# do_action method

Performs an additional action.

## Syntax

```text
def do_action(action_id: str, action_params: str) -> str: ...
```

## Remarks

do_action 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. |
| ResetCRLCache | none | none | Clears the cached CRLs. |
| ResetOCSPResponseCache | none | none | Clears the cached OCSP responses. |

```text
def select_info(entity_label: str, info_type: int, clear_selection: bool) -> None: ...
```

## Remarks

Use this method to select (or filter) signature-related information for a specific signature element.

Provide the unique label of the entity that you are interested in via the *EntityLabel* parameter. Use one of the following filters, or their combination, to specify what information you are interested in:

|  |  |  |
| --- | --- | --- |
| sitEntity | 1 | Select the current entity |
| sitParentEntity | 2 | Select the parent entity of the current entity |
| sitTimestamps | 4 | Select all timestamps covering the current entity |
| sitSignatures | 8 | Select all signatures covering the current entity |
| sitSigningChain | 16 | Select the signing chain of the current entity |
| sitEmbeddedCertificates | 256 | Select all certificates embedded in the current entity |
| sitEmbeddedCRLs | 512 | Select all CRLs embedded in the current entity |
| sitEmbeddedOCSPs | 1024 | Select all OCSP responses embedded in the current entity |
| sitEmbeddedRevInfo | 1792 | Select the whole pack of embedded revocation information (certificates, CRLs and OCSPs) |
| sitUsedCertificates | 4096 | Select all the certificates used to validate this entity's chain |
| sitUsedCRLs | 8192 | Select all the CRLs used to validate this entity's chain |
| sitUsedOCSPs | 16384 | Select all the OCSP responses used to validate this entity's chain |
| sitUsedRevInfo | 28672 | Select the whole pack of revocation information used to validate this entity's chain (certificates, CRLs, OCSP responses) |

# on_notification event

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

## Syntax

```text
class XAdESVerifierNotificationEventParams(object):
  @property
  def event_id() -> str: ...

  @property
  def event_param() -> str: ...

# In class XAdESVerifier:
@property
def on_notification() -> Callable[[XAdESVerifierNotificationEventParams], None]: ...
@on_notification.setter
def on_notification(event_hook: Callable[[XAdESVerifierNotificationEventParams], None]) -> None: ...
```

## 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:

|  |  |
| --- | --- |
| 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 timestamp_server was set to a virtual:// URI. The EventParam parameter contains the TSP request (or the plain hash, depending on the value provided to timestamp_server), 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. |
| RetrieveQualifyingProperties | A QualifyingProperties is requested. This event is only fired if xades:QualifyingPropertiesReference elements are present in the signature. The EventParam parameter contains the URI value from where to retrieve the XML document. The downloaded QualifyingProperties content should be assigned to the QualifyingPropertiesContent configuration setting. |

# on_reference_validated event

Marks the end of a reference validation.

## Syntax

```text

@on_reference_validated.setter
def on_reference_validated(event_hook: Callable[[XAdESVerifierReferenceValidatedEventParams], None]) -> None: ...
```

## 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.

# on_resolve_reference event

Asks the application to resolve a reference.

## Syntax

```text
class XAdESVerifierResolveReferenceEventParams(object):
  @property
  def reference_index() -> int: ...

  @property

# In class XAdESVerifier:
@property
def on_resolve_reference() -> Callable[[XAdESVerifierResolveReferenceEventParams], None]: ...
@on_resolve_reference.setter
def on_resolve_reference(event_hook: Callable[[XAdESVerifierResolveReferenceEventParams], None]) -> None: ...
```

## 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.

# on_signature_found event

Signifies the start of signature validation.

## Syntax

```text
class XAdESVerifierSignatureFoundEventParams(object):
  @property
  def index() -> int: ...

  @property
  def entity_label() -> str: ...

  @property
  def issuer_rdn() -> str: ...

@on_signature_found.setter
def on_signature_found(event_hook: Callable[[XAdESVerifierSignatureFoundEventParams], None]) -> None: ...
```

## 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 known_certificates property.

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

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

# on_signature_validated event

Marks the completion of the signature validation routine.

## Syntax

```text

# on_tls_cert_needed event

Fires when a remote TLS party requests a client certificate.

## Syntax

```text
class XAdESVerifierTLSCertNeededEventParams(object):
  @property
  def host() -> str: ...

  @property
  def ca_names() -> str: ...

# In class XAdESVerifier:
@property
def on_tls_cert_needed() -> Callable[[XAdESVerifierTLSCertNeededEventParams], None]: ...
@on_tls_cert_needed.setter
def on_tls_cert_needed(event_hook: Callable[[XAdESVerifierTLSCertNeededEventParams], None]) -> None: ...
```

## 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 tls_client_chain 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 [on_tls_handshake](#on_tls_handshake-event) event for the given host and, if the certificate was accepted, succeeded by the [on_tls_established](#on_tls_established-event) event.

# on_tls_cert_validate event

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

## Syntax

```text
class XAdESVerifierTLSCertValidateEventParams(object):
  @property
  def server_host() -> str: ...

  @property
  def server_ip() -> str: ...

  @property
  def accept() -> bool: ...
  @accept.setter
  def accept(value) -> None: ...

# In class XAdESVerifier:
@property
def on_tls_cert_validate() -> Callable[[XAdESVerifierTLSCertValidateEventParams], None]: ...
@on_tls_cert_validate.setter
def on_tls_cert_validate(event_hook: Callable[[XAdESVerifierTLSCertValidateEventParams], None]) -> None: ...
```

## Remarks

This event is fired during a TLS handshake. Use the tls_server_chain property to access the certificate chain. In general, classes may contact a number of TLS endpoints during their work, depending on their configuration.

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

# on_tls_established event

Fires when a TLS handshake with Host successfully completes.

## Syntax

```text
class XAdESVerifierTLSEstablishedEventParams(object):
  @property
  def host() -> str: ...

  @property
  def version() -> str: ...

  @property
  def ciphersuite() -> str: ...

@on_tls_established.setter
def on_tls_established(event_hook: Callable[[XAdESVerifierTLSEstablishedEventParams], None]) -> None: ...
```

## Remarks

The class uses this event to notify the application about a successful completion of a TLS handshake.

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

# on_tls_handshake event

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

## Syntax

```text
class XAdESVerifierTLSHandshakeEventParams(object):
  @property
  def host() -> str: ...

  @property
  def abort() -> bool: ...
  @abort.setter
  def abort(value) -> None: ...

# In class XAdESVerifier:

def on_tls_handshake() -> Callable[[XAdESVerifierTLSHandshakeEventParams], None]: ...
@on_tls_handshake.setter
def on_tls_handshake(event_hook: Callable[[XAdESVerifierTLSHandshakeEventParams], None]) -> None: ...
```

## Remarks

The class uses this event to notify the application about the start of a new TLS handshake to *Host*. If the handshake is successful, this event will be followed by the [on_tls_established](#on_tls_established-event) event. If the server chooses to request a client certificate, the [on_tls_cert_needed](#on_tls_cert_needed-event) event will also be fired.

# on_tls_shutdown event

Reports the graceful closure of a TLS connection.

## Syntax

```text
class XAdESVerifierTLSShutdownEventParams(object):
  @property
  def host() -> str: ...

# XAdESVerifier Config Settings

 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) method.

### XAdESVerifier 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.

**DataObjectFormatObjectReference[Index]**: Specifies the DataObjectFormat's ObjectReference.This property contains the DataObjectFormat's ObjectReference element that reference the ds:Reference element of the ds:Signature corresponding with the data object qualified by this property.

For example, if the corresponding ds:Reference element has an Id "reference-id-1", then you should set this property to "#reference-id-1" value.

Index value could be omitted for the first DataObjectFormat element.

**DataType**: Specifies the external data type.Use this property to specify the type of the external data (either [data_file](#data_file-property), data_stream or [data_bytes](#data_bytes-property) 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:

- **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.

**DetachedResourceURI**: Specifies a detached resource URI.Specifies a URI of the provided data, usually the data filename if stored along with a detached signature.

**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). 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.

**ExclusiveCanonicalizationPrefix**: Specifies the exclusive canonicalization prefix.Specifies the prefix for the ec:InclusiveNamespaces element for the exclusive canonicalization.

Default value is "ec". In this case "ec:" prefix will be used.

Special values:

|  |  |
| --- | --- |
| "#default" or "" | indicates that the prefix will be omitted. |
| "#auto" | indicates that the prefix will be auto-detected based on the parent nodes. |

**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 trusted_certificates 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.

**InclusiveNamespacesPrefixList**: Specifies the InclusiveNamespaces PrefixList.Use this property to read/specify InclusiveNamespaces PrefixList for exclusive canonicalization transform of SignedInfo element. See XML-Signature Syntax and Processing specification for details.

**InsertBeforeXMLElement**: Defines the reference XML element for signature insertion.Use this property to specify XML element before which the signature should be inserted, but it must be under the element specified by the [new_sig_xml_element](#XAdESVerifier_p_NewSigXMLElement) property.

Supported values are:

|  |  |
| --- | --- |
| "" | an empty string indicates the Document element |
| "#id" | indicates an XML element with specified Id |
| XPath expression | indicates an XML element selected using XPath expression. Use [add_known_namespace](#add_known_namespace-method) method to specify Prefixes and NamespaceURIs For example: "/root/data[1]" - indicates the second "data" element under the document element with a name "root" "//ns1:data" - indicates a data element. "ns1" prefix should be defined via [add_known_namespace](#add_known_namespace-method) 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.

The empty elements in the custom XML content act as a placeholder for auto-generated elements.

For example to change the order of ds:KeyValue and ds:X509Data auto-generated elements use the value: "<X509Data/><KeyValue/>"

**KeyInfoDetails**: Specifies the signing key info details to include to the signature.Contains a comma-separated list of values that specifies which signing key info details to include to the signature.

Supported values are:

|  |  |  |
| --- | --- | --- |
| certificate |  | Base64-encoded [X509v3] certificate is placed to the signature |
| issuerserial |  | X.509 issuer distinguished name/serial number pair are placed to the signature |
| subjectname |  | X.509 subject distinguished name is placed to the signature |
| ski |  | Base64 encoded plain (i.e. non-DER-encoded) value of a X509 V.3 SubjectKeyIdentifier extension is placed to the signature |
| 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.

**ManifestCount**: TBD.TBD

**PromoteLongOCSPResponses**: Whether long OCSP responses are requested. Set this property to True to force the class to publish the 'long' form of OCSP responses. Otherwise, only BasicOCSPResponse blobs are promoted.

**PSSUsed**: Whether to use RSASSA-PSS algorithm.Although the RSASSA-PSS algorithm provides better security than a classic RSA scheme (PKCS#1-1.5), please take into account that RSASSA-PSS is a relatively new algorithm which may not be understood by older implementations. This is an alias for *UsePSS*.

**QualifyingPropertiesID**: Specifies the ID for QualifyingProperties element.This property contains the identifier (ID) attribute of the xades:QualifyingProperties element.

Supported values are:

|  |  |  |
| --- | --- | --- |
| SigAndRefs |  | SigAndRefs timestamp |
| RefsOnly |  | RefsOnly timestamp |

**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 Default.

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. The individual settings remain available for advanced configuration and can be used after this setting to override specific values.

**SchemeParams**: The algorithm scheme parameters to employ.Use this property to specify the parameters of the algorithm scheme if needed.

This setting is used to provide parameters for some cryptographic schemes. Use the Name1=Value1;Name2=Value2;... syntax to encode the parameters. For example: *Scheme=PSS;SaltSize=32;TrailerField=1*.

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.
