PDFVerifier Class

Properties Methods Events Config Settings Errors

The PDFVerifier class verifies signatures over PDF documents.

Syntax

class secureblackbox.PDFVerifier

Remarks

Use PDFVerifier to validate electronic signatures over PDF documents. Generic and PAdES signatures are supported.

PDFVerifier validates each signature from two perspectives: the integrity and validity of the signature itself (i.e. its correspondence to the document data it covers), and the validity and trustworthiness of the signing certificate chain. These two signature aspects are generally independent of each other: the signature may be valid but the chain may not be trusted, or the other way around, the chain may be trusted but the integrity of the signature may be violated. Under normal circumstances both the signature and the chain must be valid for the signature to be considered good.

To initiate the validation, assign the path to the signed PDF file to the input_file property (alternatively, you can provide it in a memory buffer via the input_bytes property), and call the verify method. For every signature located in the document, PDFVerifier will fire the on_signature_found event. This event lets you specify whether you want PDFVerifier to validate the signature, the chain, or both.

Note: it does not mean that any of the two is optional. This API lets you be flexible in how you validate documents in your code in accordance with the specifics of your application and its usage scenarios. For example, if your trust environment relies on certificate pinning, validating the chain by PDFVerifier internally may cause unnecessary burden on the system, in which case it may be reasonable to disable it in the event handler.

Once on_signature_found returns, PDFVerifier proceeds to the signature validation routine in accordance with the provided settings. Upon completion of the validation, the on_signature_validated event is fired, and the validation results are separately provided via the and fields of the associated signature object. Other information about the signature can be accessed via the signatures property.

The PDF format uses incremental updates to introduce changes to the document. This implies that a signature may cover not the whole document, but rather a certain revision of it. Strictly speaking, every signature in a PDF document, apart from perhaps the last one, covers just some part of the document. In most cases that part matches the revision of the document that existed before all the subsequent signatures had been added.

Because of these specifics of the PDF format, it is crucially important to understand which part of the document is covered by a specific signature. Use the field to establish the scope of a signature. The revision of the document covered by that specific signature ranges from byte 0 to CoverageEndsAt. Alternatively, you can use the get_signed_version method to extract the signed revision to a file.

Useful settings and properties

The following properties of PDFVerifier may be handy when working with this class:

offline_mode lets you validate the document without contacting online revocation sources. Paired with switched-off system trust settings, it can be used to establish the long-term validity of the document and the completeness of the validation material included in it.
revocation_check lets you adjust the revocation checking preferences.
returns the signing time as recorded in the embedded signature timestamp. This is in contrast to , which returns the signing time as specified by the signer.
is a great way to find out the details of chain validation failures. This property returns a comprehensive validation log that reports all the issues encountered during the validation.
If the document is encrypted (in addition to being signed), the on_encrypted event will fire, asking you for the decryption certificate or password.

By default, PDFVerifier uses the system trust settings to establish certificate chain validity. You can configure it to use your own, custom validation environment by providing the necessary trust elements via known_certificates, trusted_certificates, known_crls, and other similar properties.

Syntax

def get_revocation_check() -> int: ...
def set_revocation_check(value: int) -> None: ...

Default Value

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.

The validity of the same signature may differ depending on the time point chosen due to temporal changes in chain validities, revocation statuses, and timestamp times.

close Method

Closes an opened document.

Syntax

def close(save_changes: bool) -> None: ...

Remarks

Use this method to close a previously opened document. The SaveChanges parameter is only taken into account if the document was opened in edit mode.

config Method

Sets or retrieves a configuration setting.

Syntax

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 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, you must call Config("PROPERTY"). The value will be returned as a string.

do_action Method

Performs an additional action.

Syntax

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;....

get_attached_bytes Method

Saves a PDF attachment to a byte array.

Syntax

def get_attached_bytes(index: int) -> bytes: ...

Remarks

Use this method to retrieve the contents of an attached file as a byte array.

get_attached_file Method

Saves a PDF attachment to a file.

Syntax

def get_attached_file(index: int, path: str) -> None: ...

Remarks

Use this method to retrieve the contents of an attached file and save it to a file.

get_signed_version Method

Returns the part of the document that is covered by the signature.

Syntax

def get_signed_version(sig_index: int) -> None: ...

Remarks

Use this method to retrieve the revision of the document that is covered by the SigIndex signature.

PDF documents often use the incremental updates approach, with any changes being appended to the document without altering the existing revision. This may lead to situations where a signature only covers a part of the document (one of the past revisions), but not the subsequent changes. This method provides means to extract the revision that is actually certified by the signature.

It is recommended that you use this method when validating signatures to make sure the signature covers what you expect it to cover.

An alternative to this method is to check the field of the signature object and match it to the document length.

open Method

Opens a document for verifying or removing signatures.

Syntax

def open(edit_mode: bool) -> None: ...

Remarks

Use this method to open a document for verifying or removing signatures, or for extracting signed content. When finished, call close to complete the operation and release any allocated resources.

Set EditMode to true to open the document in edit mode (only useful if you intend to remove signatures).

revalidate Method

Revalidates a signature in accordance with current settings.

Syntax

def revalidate(index: int) -> None: ...

Remarks

Use this method to revalidate a signature in the opened PDF document.

unsign Method

Deletes a signature from the document.

Syntax

def unsign(sig_index: int, unsign_kind: int) -> None: ...

Remarks

Use this method to delete an existing signature from the document. Use the SigIndex parameter to specify the signature to be removed.

Unsigning is different from get_signed_version. The latter returns the revision of the document including the mentioned signature (thus removing anything added after that signature was created). unsign removes the signature completely by carving it out of the document.

The following unsign kinds are currently supported:


uskDefault (0)	The default option.
uskFull (1)	Remove the signature fully. This is also the default option.
uskKeepField (2)	Only remove the signature, but keep the form field it is in.
uskKeepAppearance (3)	Remove the signature, but keep the form field and its widget.

Note: SigIndex set to -1 removes all signatures in the document.

verify Method

Verifies a signed PDF document.

Syntax

def verify() -> None: ...

Remarks

Use this method to validate all signatures in a PDF document.

This method walks through a signed document and reports every signature via the on_signature_found event. Subscribe to the event to be notified about the signatures and adjust validation settings on the fly.

Upon completion of this method, the signature details will be published in the signatures property.

This method only validates the signatures, but does not check their coverage. It is a good idea to use mechanisms such as get_signed_version or to ensure that the signature covers the expected document revision.

on_chain_element_download Event

Fires when there is a need to download a chain element from an online source.

Syntax

class PDFVerifierChainElementDownloadEventParams(object):
  @property
  def kind() -> int: ...

  @property

@on_chain_element_download.setter
def on_chain_element_download(event_hook: Callable[[PDFVerifierChainElementDownloadEventParams], None]) -> None: ...

Remarks

Subscribe to this event to be notified about validation element retrievals. Use the Action parameter to suppress the download if required.


veaAuto	`0`	Handle the action automatically (the default behaviour)
veaContinue	`1`	Accept the request implied by the event (accept the certificate, allow the object retrieval)
veaReject	`2`	Reject the request implied by the event (reject the certificate, disallow the object retrieval)
veaAcceptNow	`3`	Accept the validated certificate immediately
veaAbortNow	`4`	Abort the validation, reject the certificate

on_chain_element_needed Event

on_chain_validated Event

Reports the completion of a certificate chain validation.

Syntax

class PDFVerifierChainValidatedEventParams(object):
  @property
  def index() -> int: ...

cvrWeakAlgorithm	`0x4000`	A weak algorithm is used in one of certificates or revocation elements
cvrUserEnforced	`0x8000`	The chain was considered invalid following intervention from a user code

on_chain_validation_progress Event

This event is fired multiple times during chain validation to report various stages of the validation procedure.

Syntax

class PDFVerifierChainValidationProgressEventParams(object):
  @property
  def event_kind() -> str: ...

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

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

  @property
  def action() -> int: ...
  @action.setter
  def action(value) -> None: ...

# In class PDFVerifier:
@property
def on_chain_validation_progress() -> Callable[[PDFVerifierChainValidationProgressEventParams], None]: ...
@on_chain_validation_progress.setter
def on_chain_validation_progress(event_hook: Callable[[PDFVerifierChainValidationProgressEventParams], None]) -> None: ...

Remarks

Subscribe to this event to be notified about chain validation progress. Use the Action parameter to alter the validation flow.

The EventKind parameter reports the nature of the event being reported. The CertRDN and CACertRDN parameters report the distinguished names of the certificates that are relevant for the event invocation (one or both can be empty, depending on EventKind). Use the Action parameter to adjust the validation flow.


veaAuto	`0`	Handle the action automatically (the default behaviour)
veaContinue	`1`	Accept the request implied by the event (accept the certificate, allow the object retrieval)
veaReject	`2`	Reject the request implied by the event (reject the certificate, disallow the object retrieval)
veaAcceptNow	`3`	Accept the validated certificate immediately
veaAbortNow	`4`	Abort the validation, reject the certificate

on_document_loaded Event

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

Syntax

class PDFVerifierDocumentLoadedEventParams(object):
  @property
  def cancel() -> bool: ...
  @cancel.setter
  def cancel(value) -> None: ...

# In class PDFVerifier:
@property
def on_document_loaded() -> Callable[[PDFVerifierDocumentLoadedEventParams], None]: ...
@on_document_loaded.setter
def on_document_loaded(event_hook: Callable[[PDFVerifierDocumentLoadedEventParams], None]) -> None: ...

Remarks

The handler for this event is a good place to check the document structure, which may be useful when preparing the signature. For example, you can use the pages information to find the optimal position for the signature widget.

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

on_encrypted Event

Notifies the application that the document is encrypted and provides recipient certificate details if asymmetric encryption was used to encrypt the document.

Syntax

class PDFVerifierEncryptedEventParams(object):
  @property
  def cert_used() -> bool: ...

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

  @property
  def serial_number() -> bytes: ...

  @property
  def subject_key_id() -> bytes: ...

  @property
  def need_credential() -> bool: ...

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

# In class PDFVerifier:
@property
def on_encrypted() -> Callable[[PDFVerifierEncryptedEventParams], None]: ...
@on_encrypted.setter
def on_encrypted(event_hook: Callable[[PDFVerifierEncryptedEventParams], None]) -> None: ...

Remarks

The class fires this event when processing encrypted documents to report the fact of encryption and pass certificate parameters to the user.

This event fires repeatedly for each encryption mechanism used in the document until the user provides the correct credential via the decryption_certificate or password property (depending on the encryption method used), or sets SkipThis to true.

The CertUsed parameter specifies the encryption method used. If set to true, it indicates that the document uses asymmetric (certificate-based) encryption. In that case, the IssuerRDN, SerialNumber, and SubjectKeyID parameters provide the details of the encryption certificate. Note that the document can be encrypted with more than one certificate (or have "more than one recipient"), in which case each certificate will invoke its own on_encrypted event loop.

CertUsed set to false indicates that the document uses password encryption. In this case, provide the password via the password property.

The NeedCredential parameter specifies whether the correct credential is already available to the class or still needs to be set. One example where NeedCredential would be set to false is where it had been provided by the application prior to processing the document (e.g. by setting the password property to a known pre-defined value). If NeedCredential is set to true, you must provide the valid credential for the decryption process to succeed.

on_error Event

Information about errors during signing/validation.

Syntax

class PDFVerifierErrorEventParams(object):
  @property
  def error_code() -> int: ...

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

# In class PDFVerifier:
@property
def on_error() -> Callable[[PDFVerifierErrorEventParams], None]: ...
@on_error.setter
def on_error(event_hook: Callable[[PDFVerifierErrorEventParams], None]) -> None: ...

Remarks

The event is fired in case of exceptional conditions during PDF processing.

ErrorCode contains an error code and Description contains a textual description of the error.

on_notification Event

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

Syntax

class PDFVerifierNotificationEventParams(object):
  @property
  def event_id() -> str: ...

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

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

on_signature_found Event

Signifies the start of signature validation.

Syntax

class PDFVerifierSignatureFoundEventParams(object):
  @property
  def index() -> int: ...

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

  @property
  def serial_number() -> bytes: ...

# In class PDFVerifier:
@property
def on_signature_found() -> Callable[[PDFVerifierSignatureFoundEventParams], None]: ...
@on_signature_found.setter
def on_signature_found(event_hook: Callable[[PDFVerifierSignatureFoundEventParams], 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

class PDFVerifierSignatureValidatedEventParams(object):
  @property
  def index() -> int: ...

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

  @property
  def serial_number() -> bytes: ...

def on_signature_validated() -> Callable[[PDFVerifierSignatureValidatedEventParams], None]: ...
@on_signature_validated.setter
def on_signature_validated(event_hook: Callable[[PDFVerifierSignatureValidatedEventParams], None]) -> None: ...

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

on_timestamp_found Event

Signifies the start of a timestamp validation routine.

class PDFVerifierTimestampFoundEventParams(object):
  @property
  def index() -> int: ...

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

  @property
  def serial_number() -> bytes: ...

  @property

def on_timestamp_found() -> Callable[[PDFVerifierTimestampFoundEventParams], None]: ...
@on_timestamp_found.setter
def on_timestamp_found(event_hook: Callable[[PDFVerifierTimestampFoundEventParams], None]) -> None: ...

Remarks

This event fires for every timestamp identified during signature processing, and reports the details about the signer's certificate via its IssuerRDN, SerialNumber, and SubjectKeyID parameters.

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

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

on_timestamp_validated Event

Reports the completion of the timestamp validation routine.

Syntax

class PDFVerifierTimestampValidatedEventParams(object):
  @property
  def index() -> int: ...

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

  @property
  def serial_number() -> bytes: ...

  @property

@property
def on_timestamp_validated() -> Callable[[PDFVerifierTimestampValidatedEventParams], None]: ...
@on_timestamp_validated.setter
def on_timestamp_validated(event_hook: Callable[[PDFVerifierTimestampValidatedEventParams], None]) -> None: ...

Remarks

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

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

on_tls_cert_needed Event

Fires when a remote TLS party requests a client certificate.

Syntax

class PDFVerifierTLSCertNeededEventParams(object):
  @property
  def host() -> str: ...

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

# In class PDFVerifier:
@property
def on_tls_cert_needed() -> Callable[[PDFVerifierTLSCertNeededEventParams], None]: ...
@on_tls_cert_needed.setter
def on_tls_cert_needed(event_hook: Callable[[PDFVerifierTLSCertNeededEventParams], 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 event for the given host and, if the certificate was accepted, succeeded by the on_tls_established 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

class PDFVerifierTLSCertValidateEventParams(object):
  @property
  def server_host() -> str: ...

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

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

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

class PDFVerifierTLSEstablishedEventParams(object):
  @property
  def host() -> str: ...

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

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

  @property
  def connection_id() -> bytes: ...

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

# In class PDFVerifier:
@property
def on_tls_established() -> Callable[[PDFVerifierTLSEstablishedEventParams], None]: ...
@on_tls_established.setter
def on_tls_established(event_hook: Callable[[PDFVerifierTLSEstablishedEventParams], 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

class PDFVerifierTLSHandshakeEventParams(object):
  @property
  def host() -> str: ...

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

# In class PDFVerifier:
@property
def on_tls_handshake() -> Callable[[PDFVerifierTLSHandshakeEventParams], None]: ...
@on_tls_handshake.setter
def on_tls_handshake(event_hook: Callable[[PDFVerifierTLSHandshakeEventParams], 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 event. If the server chooses to request a client certificate, the on_tls_cert_needed event will also be fired.

on_tls_shutdown Event

Reports the graceful closure of a TLS connection.

Syntax

class PDFVerifierTLSShutdownEventParams(object):
  @property
  def host() -> str: ...

# In class PDFVerifier:
@property
def on_tls_shutdown() -> Callable[[PDFVerifierTLSShutdownEventParams], None]: ...
@on_tls_shutdown.setter
def on_tls_shutdown(event_hook: Callable[[PDFVerifierTLSShutdownEventParams], None]) -> None: ...

Remarks

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

PDFVerifier 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 method.

PDFVerifier Config Settings

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).

EmptySignatureFieldAddRevInfo[Index]: Specifies if revocation checking should be performed.

This property contains True if the viewing application should check the signing certificate revocation info and include the revocation information within the signature value.

EmptySignatureFieldAlternateName[Index]: Contains an alternate field name.

This property contains an alternate field name to be used in place of the actual field name wherever the field must be identified in the user interface.

EmptySignatureFieldCount: The number of empty signature form fields.

Returns the number of empty signature form fields available.

EmptySignatureFieldFlags[Index]: The field flags of the signature form field.

This property contains the empty signature form field flags ("Ff" entry in the signature field dictionary).

EmptySignatureFieldHeight[Index]: The Height of the empty signature form field.

This property contains the height of the empty signature form field.

EmptySignatureFieldInvisible[Index]: The visibility status of the field.

This property contains True if the empty signature form field is visible.

EmptySignatureFieldLegalAttestations[Index]: Specifies the legal attestations that are associated with the signature.

This property contains the legal attestations that are associated with the signature.

EmptySignatureFieldMappingName[Index]: The mapping name to be used when exporting form field data from the document.

This property contains the name to be used when exporting form field data from the document.

EmptySignatureFieldName[Index]: Textual field name.

This property contains the empty signature field name.

EmptySignatureFieldOffsetX[Index]: The field's offset from the left page border.

This property contains the horizontal offset of the empty signature form field.

EmptySignatureFieldOffsetY[Index]: The field's offset from the bottom page border.

This property contains the vertical offset of the empty signature form field.

EmptySignatureFieldPage[Index]: The index of the form field's page in the document.

This property contains the index of the empty signature form field's page in the document.

EmptySignatureFieldRequiredAllowedChanges[Index]: Specifies the changes allowed by the signature.

This property contains the changes that are allowed to the document when the signature field is signed.

EmptySignatureFieldRequiredConstraints[Index]: Specifies the required Seed Value Dictionary (SVD) constraints.

This property contains the required SVD constraints. If a certain bit in RequiredConstraints is switched on, the corresponding data item is constrained.

EmptySignatureFieldRequiredDigestAlgorithms[Index]: Specifies the required digest algorithms.

This property contains the list of the digest algorithms used for signature generation.

EmptySignatureFieldRequiredFilter[Index]: Specifies the required filter.

This property contains the required filter (name of the preferred signature handler) to use for signature generation.

EmptySignatureFieldRequiredLockAction[Index]: Indicates which set of fields shall be locked.

This property contains a set of form fields that shall be locked when the current signature field is signed.

EmptySignatureFieldRequiredLockFields[Index]: Indicates the fields that shall be locked on signing.

This property contains the list of form field names that shall be locked when the current signature field is signed. Whether this list shall be included or excluded is defined by the EmptySignatureFieldRequiredLockAction[Index] property.

EmptySignatureFieldRequiredReasons[Index]: Specifies the required reasons.

This property contains the required reasons used for signature generation.

EmptySignatureFieldRequiredSubfilters[Index]: Specifies the required subfilters.

This property contains the list of subfilters required by the signature. A subfilter represents the encoding to use when signing the PDF form.

EmptySignatureFieldTimestampRequired[Index]: Specifies if the signature should be timestamped.

This property contains True if the signature should be timestamped.

EmptySignatureFieldTSPURL[Index]: URL for a TSP server.

This property contains the TSP server URL.

EmptySignatureFieldWidth[Index]: The Width of the empty signature form field.

This property contains the width of the empty signature form field.

EncryptionHandlerName: Specifies the custom security handler PDF-name.

Specifies the custom security handler PDF-name for the encryption handler.

ForceCompleteChainValidation: Whether to check issuer (CA) certificates when the signing certificate is invalid.

Specifies whether to check issuer (CA) certificates when the signing 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). The 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.

HardenedKeyGeneration: Specifies if hardened Key generation should be used.

Specifies if hardened Key generation should be used when the AES-256 encryption algorithm and password encryption are used.

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.

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 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.

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.

PageInfoCount: The number of pages.

Returns the number of pages available.

PageInfoCropBoxEmpty[Index]: Check if the page's crop box is empty or not.

This property contains True if the crop box is empty, and False otherwise. The crop box defines the region to which the contents of the page shall be clipped (cropped) when displayed or printed.

PageInfoCropLLX[Index]: Defines the X coordinate of the lower left corner of the crop box.

This property contains the X coordinate of the lower left corner of the crop box of the page. The crop box defines the region to which the contents of the page shall be clipped (cropped) when displayed or printed.

PageInfoCropLLY[Index]: Defines the Y coordinate of the lower left corner of the crop box.

This property contains the Y coordinate of the lower left corner of the crop box of the page. The crop box defines the region to which the contents of the page shall be clipped (cropped) when displayed or printed.

PageInfoCropURX[Index]: Defines the X coordinate of the upper right corner of the crop box.

This property contains the X coordinate of the upper right corner of the crop box of the page. The crop box defines the region to which the contents of the page shall be clipped (cropped) when displayed or printed.

PageInfoCropURY[Index]: Defines the Y coordinate of the upper right corner of the crop box.

This property contains the Y coordinate of the upper right corner of the crop box of the page. The crop box defines the region to which the contents of the page shall be clipped (cropped) when displayed or printed.

PageInfoHeight[Index]: The Height of the page.

This property contains the page height value.

PageInfoMediaLLX[Index]: Defines the X coordinate of the lower left corner of the media box.

This property contains the X coordinate of the lower left corner of the media box of the page. The media box defines the boundaries of the physical medium on which the page is to be printed.

PageInfoMediaLLY[Index]: Defines the Y coordinate of the lower left corner of the media box.

This property contains the Y coordinate of the lower left corner of the media box of the page. The media box defines the boundaries of the physical medium on which the page is to be printed.

PageInfoMediaURX[Index]: Defines the X coordinate of the upper right corner of the media box.

This property contains the X coordinate of the upper right corner of the media box of the page. The media box defines the boundaries of the physical medium on which the page is to be printed.

PageInfoMediaURY[Index]: Defines the Y coordinate of the upper right corner of the media box.

This property contains the Y coordinate of the upper right corner of the media box of the page. The media box defines the boundaries of the physical medium on which the page is to be printed.

PageInfoRotate[Index]: The Rotate value of the page.

This property contains the page rotation angle.

PageInfoUserUnit[Index]: Defines the size of default user space units.

This property contains a positive number that shall give the size of default user space units, in multiples of 1/72 inch. The default value is 1.0 (user space unit is 1/72 inch).

PageInfoWidth[Index]: The Width of the page.

This property contains the page width value.

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 RSASSA-PSS mode was used.

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.

RC4KeyBits: Specifies the number of key bits used for the RC4 algorithm.

Specifies the number of key bits used for the RC4 encryption algorithm.

TolerateMinorChainIssues: Whether to tolerate minor chain issues.

This parameter controls whether the chain validator should tolerate minor technical issues when validating the chain. Those are:

CA, revocation source, TLS key usage requirements are not mandated
Violation of OCSP issuer requirements are ignored
The AuthorityKeyID extension in CRL- and certificate-issuing CAs are ignored (helps with incorrectly renewed certificates)
Basic constraints and name constraints of CA certificates are ignored
Some weaker algorithms are tolerated

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

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

UseSystemCertificates: Enables or disables the use of the system certificates.

Use this property to tell the chain validation module to automatically look up missing CA certificates in the system certificates. In many cases it is beneficial to switch this property on, as the operating system certificate configuration provides a representative trust framework.

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.

Base Config Settings

CheckKeyIntegrityBeforeUse: Enables or disable private key integrity check before use.

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

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

CookieCaching: Specifies whether a cookie cache should be used for HTTP(S) transports.

Set this property to enable or disable cookies caching for the class.

Supported values are:


off		No caching (default)
local		Local caching

Cookies: Gets or sets local cookies for the class.

Use this property to get cookies from the internal cookie storage of the class and/or restore them back between application sessions.

DefDeriveKeyIterations: Specifies the default key derivation algorithm iteration count.

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

EnableClientSideSSLFFDHE: Enables or disables finite field DHE key exchange support in TLS clients.

This global property enables or disables support for finite field DHE key exchange methods in TLS clients. FF DHE is a slower algorithm if compared to EC DHE; enabling it may result in slower connections.

This setting only applies to sessions negotiated with TLS version 1.3.

GlobalCookies: Gets or sets global cookies for all the HTTP transports.

Use this property to get cookies from the GLOBAL cookie storage or restore them back between application sessions. These cookies will be used by all the classes that have its CookieCaching property set to "global".

HttpUserAgent: Specifies the user agent name to be used by all HTTP clients.

This global setting defines the User-Agent field of the HTTP request provides information about the software that initiates the request. This value will be used by all the HTTP clients including the ones used internally in other classes.

Contains a comma-separated list of value pairs ("name:value") that describe filters.

Supported filter names are:


exclude-package		Exclude a package specified in the value
exclude-module		Exclude a module specified in the value
exclude-class		Exclude a class specified in the value
exclude-method		Exclude a method specified in the value
include-package		Include a package specified in the value
include-module		Include a module specified in the value
include-class		Include a class specified in the value
include-method		Include a method specified in the value

LogFlushMode: Specifies the log flush mode.

Use this property to set the log flush mode. The following values are defined:


none		No flush (caching only)
immediate		Immediate flush (real-time logging)
maxcount		Flush cached entries upon reaching LogMaxEventCount entries in the cache.

LogLevel: Specifies the debug log level.

Use this property to provide the desired debug log level.

Supported values are:


none		None (by default)
fatal		Severe errors that cause premature termination.
error		Other runtime errors or unexpected conditions.
warning		Use of deprecated APIs, poor use of API, 'almost' errors, other runtime situations that are undesirable or unexpected, but not necessarily "wrong".
info		Interesting runtime events (startup/shutdown).
debug		Detailed information on flow of through the system.
trace		More detailed information.

LogMaxEventCount: Specifies the maximum number of events to cache before further action is taken.

Use this property to specify the log event number threshold. This threshold may have different effects, depending on the rotation setting and/or the flush mode.

The default value of this setting is 100.

LogRotationMode: Specifies the log rotation mode.

Use this property to set the log rotation mode. The following values are defined:


none		No rotation
deleteolder		Delete older entries from the cache upon reaching LogMaxEventCount
keepolder		Keep older entries in the cache upon reaching LogMaxEventCount (newer entries are discarded)

MaxASN1BufferLength: Specifies the maximal allowed length for ASN.1 primitive tag data.

This global property limits the maximal allowed length for ASN.1 tag data for non-content-carrying structures, such as certificates, CRLs, or timestamps. It does not affect structures that can carry content, such as CMS/CAdES messages. This is a security property aiming at preventing DoS attacks.

MaxASN1TreeDepth: Specifies the maximal depth for processed ASN.1 trees.

This global property limits the maximal depth of ASN.1 trees that the component can handle without throwing an error. This is a security property aiming at preventing DoS attacks.

OCSPHashAlgorithm: Specifies the hash algorithm to be used to identify certificates in OCSP requests.

This global setting defines the hash algorithm to use in OCSP requests during chain validation. Some OCSP responders can only use older algorithms, in which case setting this property to SHA1 may be helpful.

StaticDNS: Specifies whether static DNS rules should be used.

Set this property to enable or disable static DNS rules for the class. Works only if UseOwnDNSResolver is set to true.

Supported values are:


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

StaticIPAddress[domain]: Gets or sets an IP address for the specified domain name.

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

StaticIPAddresses: Gets or sets all the static DNS rules.

Use this property to get static DNS rules from the current rules storage or restore them back between application sessions. If StaticDNS of the 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 chached 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).

TLSSessionPurgeInterval: Specifies how often the session cache should remove the expired TLS sessions.

Use this property to specify the time interval of purging the expired TLS sessions from the session cache. Default value is 60 seconds (1 minute).

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.

UseSystemOAEPAndPSS: Enforces or disables the use of system-driven RSA OAEP and PSS computations.

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

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

UseSystemRandom: Enables or disables the use of the OS PRNG.

Use this global property to enable or disable the use of operating system-driven pseudorandom number generation.
