def set_signing_chain_count(value: int) -> None: ...

signing_chain_count = property(get_signing_chain_count, set_signing_chain_count)

Default Value

0

Remarks

This property controls the size of the following arrays:

The array indices start at 0 and end at signing_chain_count - 1.

signing_chain_bytes Property

Returns the raw certificate data in DER format.

Syntax

def get_signing_chain_bytes(signing_chain_index: int) -> bytes: ...

Remarks

Returns the raw certificate data in DER format.

The signing_chain_index parameter specifies the index of the item in the array. The size of the array is controlled by the signing_chain_count property.

This property is read-only.

signing_chain_handle Property

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

Syntax

def get_signing_chain_handle(signing_chain_index: int) -> int: ...
def set_signing_chain_handle(signing_chain_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. pdfSigner.setSigningCertHandle(certMgr.getCertHandle());

The signing_chain_index parameter specifies the index of the item in the array. The size of the array is controlled by the signing_chain_count property.

Remarks

Use this method to add a placeholder for the entry the contents of which is to be provided on the fly from a stream or buffer.

Pass the path to the entry within the archive (e.g. Reports/report2020.csv) via the Path parameter. After the entry has been added, use on_prepare_file event or files property to tune up the type of the data source (file, stream, or memory buffer). During the actual compression, provide the contents of the entry in a stream or buffer in the on_before_compress_file event handler.

This method returns the index of the new entry in the files collection.

remove Method

Removes file(s) and/or folder(s) from the archive.

Syntax

def remove(path: str) -> None: ...

Remarks

Use this method to remove entries from the archive. Provide an archive-local path via the Path parameter.

Path supports file masks, which makes this method quite powerful (and potentially dangerous).

reset Method

Resets the class settings.

Syntax

save Method

Compresses the archive and saves it to a file.

Syntax

def save(archive_name: str) -> None: ...

Remarks

Use this method to finalize all preparations, compress all the entries set up in files collection, and write the created archive to ArchiveName file.

This method carries out a lot of work and fires a number of events during its execution. Before the compression process starts, on_prepare_file event fires repeatedly to provide the summary of what is being included into the archive. A handler of that event is a good place to make last-minute modifications to the data sources, file names, and actions to take upon the files.

Compression of each entry is surrounded with on_before_compress_file and on_after_compress_file "brackets". Subscribe to on_before_compress_file to supply the file contents for entries with Buffer and Stream data sources. on_after_compress_file is a good place to release the content stream alloated in the on_before_compress_file event handler.

on_progress event fires repeatedly to report the progress of the current and whole operations. It also provides an opportunity to abort the compression process.

save_bytes Method

Compresses the archive and saves it to a byte array.

Syntax

def save_bytes() -> bytes: ...

Remarks

Use this method to finalize all preparations and compress all entries contained in the files collection. The method returns the byte array containing the serialized archive.

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

Remarks

Class fires this event for every file included in the files collection before commencing the compression. This is the last opportunity for your code to adjust the action to be taken for each file and tune up the data sources appropriately.

The Path parameter contains the path to the file within the archive (such as Photos/myphoto.jpg), and the FileSize contains the size of that file before compression.

The DataSource parameter indicates the media from which the file contents is to be taken. A typical default value if fdsFile, but you can adjust the value of that parameter if you need to use an alternative source. The following options are available:

fdsFile (0)The data will be taken from a file indicated by the LocalPath parameter. You can change this path in this event handler.
fdsStream (1)The file data will be taken from a stream assigned to file_stream property.
fdsBuffer (2)The data will be taken from a buffer attached to the file_data property.
Please do not assign file_stream or file_data in this event handler: this should be done further down the road in the on_before_compress_file event handler. The purpose of this event is to prepare the compression plan by summarizing what should be done and to which files.

The Action parameter, which is also tuneable, indicates the action for class to take on the file:

atAdd (0)Add the file to the archive
atKeep (1)Keep the existing file in the archive
atUpdate (2)Update the archived file with a fresher copy
atDelete (3)Delete the file from the archive
atExtract (4)Extract the file (extraction only)
atSkip (5)Skip file extraction (extraction only)

on_progress Event

on_recipient_found Event

Signifies that the archive was found to be encrypted with a digital certificate.

Syntax

class ArchiveWriterRecipientFoundEventParams(object):
  @property
  def public_key_hash() -> str: ...

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

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

Remarks

The class fires this event to notify the application that the archive was found to be encrypted with a digital certificate. The hash of the certificate's public key is provided in the PublicKeyHash parameter.

CertFound indicates whether a certificate with a matching public key hash was found in the decryption_certificates list. If it wasn't, you need to locate it on the system and add it to that list: class won't be able to decrypt the archive otherwise.

Please note that the certificate must have an associated private key to be capable of decryption.

ArchiveWriter 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.

ArchiveWriter Config Settings

EncryptionKeyLength:   Sets the length of encryption key for WinZip-type protected archives.

Use this configuration setting to specify the symmetric key length to use. Supported values are 128, 192, and 256; or 0 for the default length.

FilenamesCharset:   The character set to apply to archived file names.

Use this setting to apply a specific charset to the names of the archived files:

writer.Config("FilenamesCharset=cp852");

ForceUStar:   Enables UStar extension for new TAR archives.

Set this property to true to enable the UStar extension for TAR archives. This allows for recording very long filenames.

TempPath:   Path for storing temporary files.

This setting specifies an absolute path to the location on disk where temporary files are stored.

UsePax:   Enables use of PAX algorithm when creating TAR directories.

Use this setting to enable or disable the use of PAX algorithm when TARring directories.

UseUStar:   Enables use of UStar variant of file name packaging when creating TAR directories.

This is a performance setting. It is unlikely that you will ever need to adjust it.

AssignSystemSmartCardPins:   Specifies whether CSP-level PINs should be assigned to CNG keys.

This is a low-level tweak for certain cryptographic providers. It is unlikely that you will ever need to adjust it.

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

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

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

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).

UseInternalRandom:   Switches between SecureBlackbox-own and platform PRNGs.

Allows to switch between internal/native PRNG implementation and the one provided by the platform.

UseLegacyAdESValidation:   Enables legacy AdES validation mode.

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

UseOwnDNSResolver:   Specifies whether the client components should use own DNS resolver.

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

UseSharedSystemStorages:   Specifies whether the validation engine should use a global per-process copy of the system certificate stores.

Set this global property to false to make each validation run use its own copy of system certificate stores.

UseSystemNativeSizeCalculation:   An internal CryptoAPI access tweak.

This is an internal setting. Please do not use it unless instructed by the support team.

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

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

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

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

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