# Struct secureblackbox::ArchiveReader

The ArchiveReader struct supports inspection and extraction of files from zip, tar, gzip and bzip2 archives.

## Syntax

```text
secureblackbox::ArchiveReader
```

## Remarks

ArchiveReader offers capabilities of inspecting, editing, and unpacking archived files from a variety of archive formats.

```text
ArchiveReader archiveReader = new ArchiveReader();

archiveReader.setDecryptionPassword("MyPassword"); // the decryption password for the archive

// Opens the archive file, first param is the archive type and the second one the path of the archive
archiveReader.open(ArchiveReader.aftZip,"C:/MyArchives/folder.zip");

// extract all the files to the path provided
archiveReader.extractAll("C:/Extracted/extractedFolder");
```

The following common archive formats are supported:

- ZIP (.zip)
- GZip (.gz)
- BZip2 (.bz2)
- Tar+GZip (.tar.gz)
- Tar+Bzip2 (.tar.bz2)

### Working with ArchiveReader

 Work with ArchiveReader builds on the following steps:

**Opening the archive.**

 On this step the component loads the provided compressed data into its memory. You can pass the compressed data as a byte array ([open_bytes](#open_bytes-method-archivereader-struct)), as a stream (open_stream), or load it from a disk file ([open](#open-method-archivereader-struct)).

**Inspecting the archive contents**

 Use the files collection to access information about individual files stored in the opened archive. On this stage you can adjust the individual files objects' > and > properties to configure bespoke processing for specific files.

**Extracting the files**

 Call [extract_all](#extract_all-method-archivereader-struct) to initiate extraction of all the files contained in the archive and selected using the > property, or [extract](#extract-method-archivereader-struct) to extract a single file. The component notifies your code about each individual extraction using its [on_before_extract_file](#on_before_extract_file-event-archivereader-struct) and [on_after_extract_file](#on_after_extract_file-event-archivereader-struct) events. You can use [on_before_extract_file](#on_before_extract_file-event-archivereader-struct) to provide your final decision about the extraction of a particular file.

Use [decryption_password](#decryption_password-property-archivereader-struct) property to specify a decryption password for an archive and/or a specific entry within it. If the password is required but wasn't set, or if the provided password is wrong, the component will fire the [on_decryption_password_needed](#on_decryption_password_needed-event-archivereader-struct) event. This event is fired repeatedly until the correct password is provided or its *Cancel* parameter is returned as true.

**Closing the archive**

 Once you are finished with the archive, call the component's [close](#close-method-archivereader-struct) method to close the archive file and release the associated memory.

### Object Lifetime

 The *new()* method returns a mutable reference to a struct instance. The object itself is kept in the global list maintained by SecureBlackbox. Due to this, the ArchiveReader struct cannot be disposed of automatically. Please, call the *dispose(&mut; self)* method of ArchiveReader when you have finished using the instance.

## Data Type

bool

# signing_cert_ca_key_id property ([ArchiveReader](#struct-secureblackboxarchivereader) Struct)

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

## Syntax

*Rust Syntax*

```text
fn signing_cert_ca_key_id(&self ) -> Result<Vec<u8>, SecureBlackboxError>
```

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

This property is read-only.

fn signing_cert_crl_distribution_points(&self ) -> Result<String, SecureBlackboxError>
```

## Default Value

""

## Remarks

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

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

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

This property is read-only.

## Data Type

String

# signing_cert_curve property ([ArchiveReader](#struct-secureblackboxarchivereader) Struct)

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

## Syntax

*Rust Syntax*

```text
fn signing_cert_curve(&self ) -> Result<String, SecureBlackboxError>

## Data Type

String

# signing_cert_fingerprint property ([ArchiveReader](#struct-secureblackboxarchivereader) Struct)

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

## Syntax

*Rust Syntax*

```text
fn signing_cert_fingerprint(&self ) -> Result<String, SecureBlackboxError>
```

## Default Value

""

## Remarks

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

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

This property is read-only.

## Data Type

String

# signing_cert_friendly_name property ([ArchiveReader](#struct-secureblackboxarchivereader) Struct)

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

## Syntax

*Rust Syntax*

```text
fn signing_cert_friendly_name(&self ) -> Result<String, SecureBlackboxError>
```

## Default Value

""

## Remarks

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

This property is read-only.

## Data Type

String

# signing_cert_handle property ([ArchiveReader](#struct-secureblackboxarchivereader) Struct)

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

## Syntax

*Rust Syntax*

```text
fn signing_cert_handle(&self ) -> Result<i64, SecureBlackboxError>
```

## Default Value

0

## Remarks

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

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

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

This property is read-only.

## Data Type

i64

# signing_cert_hash_algorithm property ([ArchiveReader](#struct-secureblackboxarchivereader) Struct)

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

## Syntax

*Rust Syntax*

```text
fn signing_cert_hash_algorithm(&self ) -> Result<String, SecureBlackboxError>
```

## Default Value

""

## Remarks

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

## Default Value

""

## Remarks

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

Note that the key fingerprint is different from the certificate fingerprint accessible via the [signing_cert_fingerprint](#signing_cert_fingerprint-property-archivereader-struct) property. The key fingerprint uniquely identifies the public key, and so can be the same for multiple certificates containing the same key.

This property is read-only.

## Data Type

String

# signing_cert_key_usage property ([ArchiveReader](#struct-secureblackboxarchivereader) Struct)

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

| ckuKeyPurposeClientAuth | 0x10000 | Kerberos - client authentication |
| ckuKeyPurposeKDC | 0x20000 | Kerberos - KDC |

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

This property is read-only.

## Data Type

i32

# signing_cert_key_valid property ([ArchiveReader](#struct-secureblackboxarchivereader) Struct)

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

## Syntax

*Rust Syntax*

```text
fn signing_cert_key_valid(&self ) -> Result<bool, SecureBlackboxError>
```

## Default Value

false

## Remarks

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

This property is read-only.

## Data Type

bool

# signing_cert_ocsp_locations property ([ArchiveReader](#struct-secureblackboxarchivereader) Struct)

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

## Syntax

*Rust Syntax*

```text
fn signing_cert_ocsp_locations(&self ) -> Result<String, SecureBlackboxError>
```

## Default Value

""

## Remarks

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

Set this property before calling the certificate manager's [generate](#CertificateManager_m_Generate) method to propagate it to the new certificate.

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

This property is read-only.

## Data Type

String

# signing_cert_policy_i_ds property ([ArchiveReader](#struct-secureblackboxarchivereader) Struct)

Contains identifiers (OIDs) of the applicable certificate policies.

## Syntax

*Rust Syntax*

```text
fn signing_cert_policy_i_ds(&self ) -> Result<String, SecureBlackboxError>
```

## Default Value

""

## Remarks

Contains identifiers (OIDs) of the applicable certificate policies.

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

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

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

This property is read-only.

## Data Type

String

# signing_cert_public_key_bytes property ([ArchiveReader](#struct-secureblackboxarchivereader) Struct)

Contains the certificate's public key in DER format.

## Syntax

*Rust Syntax*

```text
fn signing_cert_public_key_bytes(&self ) -> Result<Vec<u8>, SecureBlackboxError>
```

## Remarks

Contains the certificate's public key in DER format.

This typically would contain an ASN.1-encoded public key value. The exact format depends on the type of the public key contained in the certificate.

This property is read-only.

## Data Type

Vec

# signing_cert_self_signed property ([ArchiveReader](#struct-secureblackboxarchivereader) Struct)

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

## Syntax

*Rust Syntax*

```text
fn signing_cert_self_signed(&self ) -> Result<bool, SecureBlackboxError>
```

## Default Value

false

## Remarks

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

This property is read-only.

## Data Type

bool

# signing_cert_serial_number property ([ArchiveReader](#struct-secureblackboxarchivereader) Struct)

Returns the certificate's serial number.

## Syntax

*Rust Syntax*

```text
fn signing_cert_serial_number(&self ) -> Result<Vec<u8>, SecureBlackboxError>
```

## Remarks

Returns the certificate's serial number.

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

This property is read-only.

## Data Type

Vec

# signing_cert_sig_algorithm property ([ArchiveReader](#struct-secureblackboxarchivereader) Struct)

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

## Syntax

*Rust Syntax*

```text
fn signing_cert_sig_algorithm(&self ) -> Result<String, SecureBlackboxError>
```

## Default Value

""

## Remarks

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

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

This property is read-only.

## Data Type

String

# signing_cert_subject property ([ArchiveReader](#struct-secureblackboxarchivereader) Struct)

The common name of the certificate holder, typically an individual's name, a URL, an e-mail address, or a company name.

## Syntax

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

This property is read-only.

## Data Type

Vec

# signing_cert_subject_rdn property ([ArchiveReader](#struct-secureblackboxarchivereader) Struct)

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

## Syntax

*Rust Syntax*

```text
fn signing_cert_subject_rdn(&self ) -> Result<String, SecureBlackboxError>
```

## Default Value

""

## Remarks

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

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

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

This property is read-only.

## Data Type

String

# signing_cert_valid_from property ([ArchiveReader](#struct-secureblackboxarchivereader) Struct)

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

This property is read-only.

## Data Type

String

# signing_cert_valid_to property ([ArchiveReader](#struct-secureblackboxarchivereader) Struct)

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

## Syntax

*Rust Syntax*

```text
fn signing_cert_valid_to(&self ) -> Result<String, SecureBlackboxError>

# close method ([ArchiveReader](#struct-secureblackboxarchivereader) Struct)

Closes the current archive.

## Syntax

*Rust Syntax*

```text
fn close(&self) -> Result<(), SecureBlackboxError>
```

## Remarks

Use this method to close the archive that is currently opened and release the associated memory. You won't be able to extract files or access the archive details after closing the archive.

# config method ([ArchiveReader](#struct-secureblackboxarchivereader) Struct)

Sets or retrieves a configuration setting.

## Syntax

*Rust Syntax*

```text
fn config(&self, configuration_string : &str) ->  Result<String, SecureBlackboxError>
```

## Remarks

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

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

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

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

# do_action method ([ArchiveReader](#struct-secureblackboxarchivereader) Struct)

Performs an additional action.

## Syntax

*Rust Syntax*

```text
fn do_action(&self, action_id : &str, action_params : &str) ->  Result<String, SecureBlackboxError>
```

## Remarks

do_action is a generic method available in every struct. 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. |

# extract method ([ArchiveReader](#struct-secureblackboxarchivereader) Struct)

## Syntax

*Rust Syntax*

```text
fn extract(&self, path : &str, local_path : &str, preserve_full_path : bool) -> Result<(), SecureBlackboxError>
```

## Remarks

Use this method to extract a single file from the archive.

Pass the internal path to the entry in the archive via the *Path* parameter, and the path where to save the extracted entry via the *LocalPath* parameter. Set *PreserveFullPath* to true to enforce full-path extraction, in which case *LocalPath* would indicate the mount point at which the full *Path* needs to be rooted. If *PreserveFullPath* is false, the *LocalPath* provides the final location for the extracted file.

Use [extract_all](#extract_all-method-archivereader-struct) to extract all files at once.

# extract_all method ([ArchiveReader](#struct-secureblackboxarchivereader) Struct)

Extract all the files contained in the archive.

## Syntax

*Rust Syntax*

  pub fn on_signature_found(&self) -> &'a dyn ArchiveReaderSignatureFoundEvent;
  pub fn set_on_signature_found(&mut self, value : &'a dyn ArchiveReaderSignatureFoundEvent);
  ...
}
```

## 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 struct 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.

# Config Settings ([ArchiveReader](#struct-secureblackboxarchivereader) Struct)

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

### ArchiveReader Config Settings

**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:

```text
  writer.Config("FilenamesCharset=cp852");
```

**RestoreAttributes**: Specifies whether file and directory attributes should be restored upon extraction.Set this property to true to tell ArchiveReader to restore file attributes when extracting files from the archive.

**TempPath**: Path for storing temporary files.This setting specifies an absolute path to the location on disk where temporary files are stored. This setting is supported only in the Java edition for all applicable signing components except [PDFSigner](PDFSigner.md#PDFSigner), where this limitation does not apply.

### Base Config Settings

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

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

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

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

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

Supported values are:

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

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

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

**DNSLocalSuffix**: The suffix to assign for TLD names.Use this global setting to adjust the default suffix to assign to top-level domain names. The default is *.local*.

**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.

**EnableSSHMLKEM**: Enables support for ML-KEM/hybrid key exchange algorithms in SSH client and server components.Use this setting to enable hybrid key exchange algorithms in client and server SSH and SFTP components. This is a global setting that enables ML-KEM blanketly in all SSH-dependent components.

**EnableTLSMLKEM**: Enables support for ML-KEM and hybrid groups in TLS client and server components.Use this setting to enable ML-KEM and hybrid key exchange groups in client and server TLS components. This is a global setting that enables ML-KEM blanketly in all TLS-dependent components.

**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 structs that have its *CookieCaching* property set to "global".

**HardwareCryptoUsePolicy**: The hardware crypto usage policy.This global setting controls the hardware cryptography usage policy.

Supported Values:

|  |  |
| --- | --- |
| auto | Use hardware cryptography if available; otherwise, fall back to software-based cryptography (default). |
| enable | Always attempt to use hardware cryptography. If unavailable, exception will be thrown. |
| disable | Do not use hardware cryptography. |

**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 structs.

**HttpVersion**: The HTTP version to use in any inner HTTP client components created.Set this property to 1.0 or 1.1 to indicate the HTTP version that any internal HTTP clients should use.

**IgnoreExpiredMSCTLSigningCert**: Whether to tolerate the expired Windows Update signing certificate.It is not uncommon for Microsoft Windows Update Certificate Trust List to be signed with an expired Microsoft certificate. Setting this global property to true makes SBB ignore the expired factor and take the Trust List into account.

**ListDelimiter**: The delimiter character for multi-element lists.Allows to set the delimiter for any multi-entry values returned by the component as a string object, such as file lists. For most of the components, this property is set to a newline sequence.

**LogDestination**: Specifies the debug log destination.Contains a comma-separated list of values that specifies where debug log should be dumped.

Supported values are:

|  |  |  |
| --- | --- | --- |
| file |  | File |
| console |  | Console |

**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.

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

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

Supported Values:

|  |  |
| --- | --- |
| certificate | Enables caching of certificates. |
| crl | Enables caching of Certificate Revocation Lists (CRLs). |
| ocsp | Enables caching of OCSP (Online Certificate Status Protocol) responses. |

Example (default value):

```text
PKICache=certificate,crl,ocsp
```

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

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

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

Example:

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

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

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

**ServerSSLDHKeyLength**: Sets the size of the TLS DHE key exchange group.Use this property to adjust the length, in bits, of the DHE prime to be used by the TLS server.

**StaticDNS**: Specifies whether static DNS rules should be used.Set this property to enable or disable static DNS rules for the struct. 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 struct) or global DNS rules storage depending on the *StaticDNS* value. The type of the IP address (IPv4 or IPv6) is determined automatically. If both addresses are available, they are divided by the | (pipe) character.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Syntax:

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

Where:

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

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

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

Usage Examples:

Map OID 2.5.4.5 to SERIALNUMBER:

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

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

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

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

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

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