# external_crypto_key_id property

The ID of the pre-shared key used for DC request authentication.

## Syntax

```text
def get_external_crypto_key_id() -> str: ...
def set_external_crypto_key_id(value: str) -> None: ...
external_crypto_key_id = property(get_external_crypto_key_id, set_external_crypto_key_id)
```

## Default Value

""

## Remarks

The ID of the pre-shared key used for DC request authentication.

Asynchronous DCAuth-driven communication requires that parties authenticate each other with a secret pre-shared cryptographic key. This provides an extra protection layer for the protocol and diminishes the risk of the private key becoming abused by foreign parties. Use this property to provide the pre-shared key identifier, and use [external_crypto_key_secret](#external_crypto_key_secret-property) to pass the key itself.

The same KeyID/KeySecret pair should be used on the DCAuth side for the signing requests to be accepted.

Note: The KeyID/KeySecret scheme is very similar to the AuthKey scheme used in various Cloud service providers to authenticate users.

Example:

```text
  signer.ExternalCrypto.KeyID = "MainSigningKey";
  signer.ExternalCrypto.KeySecret = "abcdef0123456789";
```

# external_crypto_key_secret property

The pre-shared key used for DC request authentication.

## Syntax

```text
def get_external_crypto_key_secret() -> str: ...
def set_external_crypto_key_secret(value: str) -> None: ...
external_crypto_key_secret = property(get_external_crypto_key_secret, set_external_crypto_key_secret)
```

## Default Value

""

## Remarks

The pre-shared key used for DC request authentication. This key must be set and match the key used by the DCAuth counterpart for the scheme to work.

Read more about configuring authentication in the [external_crypto_key_id](#external_crypto_key_id-property) topic.

# pinned_client_cert_bytes property

Returns the raw certificate data in DER format.

## Syntax

```text
def get_pinned_client_cert_bytes(pinned_client_cert_index: int) -> bytes: ...
```

## Remarks

Returns the raw certificate data in DER format.

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

This property is read-only.

# pinned_client_cert_ca property

Indicates whether the certificate has a CA capability.

## Syntax

```text
def get_pinned_client_cert_ca(pinned_client_cert_index: int) -> bool: ...
```

## Default Value

FALSE

## Remarks

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

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

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

This property is read-only.

# pinned_client_cert_ca_key_id property

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

## Syntax

```text
def get_pinned_client_cert_ca_key_id(pinned_client_cert_index: int) -> bytes: ...
```

## Remarks

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

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

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

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

This property is read-only.

# pinned_client_cert_cert_type property

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

## Syntax

```text
def get_pinned_client_cert_cert_type(pinned_client_cert_index: int) -> int: ...
```

## Possible Values

```text
0   # Unknown1   # X509Certificate2   # X509CertificateRequest
```

## Default Value

0

## Remarks

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

A [Certificate](#Type_Certificate) object can contain two types of cryptographic objects: a ready-to-use X.509 certificate, or a certificate request ("an unsigned certificate"). Certificate requests can be upgraded to full certificates by signing them with a CA certificate.

Use the [CertificateManager](#CertificateManager) class to load or create new certificate and certificate requests objects.

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

This property is read-only.

# pinned_client_cert_crl_distribution_points property

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

## Syntax

```text
def get_pinned_client_cert_crl_distribution_points(pinned_client_cert_index: int) -> str: ...
```

## Default Value

""

## Remarks

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

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

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

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

This property is read-only.

# pinned_client_cert_curve property

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

## Syntax

```text
def get_pinned_client_cert_curve(pinned_client_cert_index: int) -> str: ...
```

## Default Value

""

## Remarks

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

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

This property is read-only.

# pinned_client_cert_fingerprint property

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

## Syntax

```text
def get_pinned_client_cert_fingerprint(pinned_client_cert_index: int) -> str: ...
```

## 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.

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

This property is read-only.

# pinned_client_cert_friendly_name property

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

## Syntax

```text
def get_pinned_client_cert_friendly_name(pinned_client_cert_index: int) -> str: ...
```

## 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.

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

This property is read-only.

# pinned_client_cert_handle property

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

## Syntax

```text
def get_pinned_client_cert_handle(pinned_client_cert_index: int) -> int: ...
```

## 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());
```

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

This property is read-only.

# pinned_client_cert_hash_algorithm property

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

## Syntax

```text
def get_pinned_client_cert_hash_algorithm(pinned_client_cert_index: int) -> str: ...
```

## 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 [pinned_client_cert_sig_algorithm](#pinned_client_cert_sig_algorithm-property) to find out the hash algorithm that is part of the certificate signature.

The common name of the certificate issuer (CA), typically a company name.

## Syntax

```text
def get_pinned_client_cert_issuer(pinned_client_cert_index: int) -> str: ...
```

## Default Value

""

## Remarks

The common name of the certificate issuer (CA), typically a company name. This is part of a larger set of credentials available via [pinned_client_cert_issuer_rdn](#pinned_client_cert_issuer_rdn-property).

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

This property is read-only.

# pinned_client_cert_issuer_rdn property

A list of Property=Value pairs that uniquely identify the certificate issuer.

## Syntax

```text
def get_pinned_client_cert_issuer_rdn(pinned_client_cert_index: int) -> str: ...
```

## Default Value

""

## Remarks

A list of ciphersuites separated with commas or semicolons. Each ciphersuite in the list may be prefixed with a minus sign (-) to indicate that the ciphersuite should be disabled rather than enabled. Besides the specific ciphersuite modifiers, this property supports the *all* (and *-all*) aliases, allowing all ciphersuites to be blanketly enabled or disabled at once.

Note: the list of ciphersuites provided to this property alters the baseline list of ciphersuites as defined by [tls_base_configuration](#tls_base_configuration-property). Remember to start your ciphersuite string with -all; if you need to only enable a specific fixed set of ciphersuites. The list of supported ciphersuites is provided below:

# tls_revocation_check property

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

## Syntax

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

```

## Default Value

1

## Remarks

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

Revocation checking is necessary to ensure the integrity of the chain and obtain up-to-date certificate validity and trustworthiness information.

|  |  |  |
| --- | --- | --- |
| crcNone | 0 | No revocation checking. |
| crcAuto | 1 | Automatic mode selection. Currently this maps to crcAnyOCSPOrCRL, but it may change in the future. |
| crcAllCRL | 2 | All provided CRL endpoints will be checked, and all checks must succeed. |
| crcAllOCSP | 3 | All provided OCSP endpoints will be checked, and all checks must succeed. |
| crcAllCRLAndOCSP | 4 | All provided CRL and OCSP endpoints will be checked, and all checks must succeed. |
| crcAnyCRL | 5 | All provided CRL endpoints will be checked, and at least one check must succeed. |
| crcAnyOCSP | 6 | All provided OCSP endpoints will be checked, and at least one check must succeed. |
| crcAnyCRLOrOCSP | 7 | All provided CRL and OCSP endpoints will be checked, and at least one check must succeed. CRL endpoints are checked first. |
| crcAnyOCSPOrCRL | 8 | All provided CRL and OCSP endpoints will be checked, and at least one check must succeed. OCSP endpoints are checked first. |

This setting controls the way the revocation checks are performed for every certificate in the chain. Typically certificates come with two types of revocation information sources: CRL (certificate revocation lists) and OCSP responders. CRLs are static objects periodically published by the CA at some online location. OCSP responders are active online services maintained by the CA that can provide up-to-date information on certificate statuses in near real time.

There are some conceptual differences between the two. CRLs are normally larger in size. Their use involves some latency because there is normally some delay between the time when a certificate was revoked and the time the subsequent CRL mentioning that is published. The benefits of CRL is that the same object can provide statuses for all certificates issued by a particular CA, and that the whole technology is much simpler than OCSP (and thus is supported by more CAs).

This setting lets you adjust the validation course by including or excluding certain types of revocation sources from the validation process. The crcAnyOCSPOrCRL setting (give preference to the faster OCSP route and only demand one source to succeed) is a good choice for most typical validation environments. The "crcAll*" modes are much stricter, and may be used in scenarios where bulletproof validity information is essential.

NOTE: If no CRL or OCSP endpoints are provided by the CA, the revocation check will be considered successful. This is because the CA chose not to supply revocation information for its certificates, meaning they are considered irrevocable.

NOTE: Within each of the above settings, if any retrieved CRL or OCSP response indicates that the certificate has been revoked, the revocation check fails.

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

## Remarks

The server uses this event to notify the application about incoming object rename requests. *OldPath* and *NewPath* contain the existing and the new path for the object. *ConnectionID* identifies the connected client.

Set *Action* to [fraAuto](constants.md#const_fraAuto) to let the server handle the request automatically, or to fraCustom to handle the request in your code.

Choose *Action* as one of the following values:

|  |  |  |
| --- | --- | --- |
| fraAuto | 1 | Handle the requested action automatically by the server |
| fraCustom | 2 | Override the action using the user code logic |
| fraAbort | 3 | Abort the requested action |

If *fraCustom* Action is chosen, this event will be followed by a [on_rename_object](#on_rename_object-event) call, where your code is expected to perform the renaming operation.

# on_external_sign event

Handles remote or external signing initiated by the server protocol.

## Syntax

```text
class WebDAVServerExternalSignEventParams(object):
  @property
  def connection_id() -> int: ...

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

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

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

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

  @property
  def signed_data() -> str: ...
  @signed_data.setter
  def signed_data(value) -> None: ...

# In class WebDAVServer:
@property
def on_external_sign() -> Callable[[WebDAVServerExternalSignEventParams], None]: ...
@on_external_sign.setter
def on_external_sign(event_hook: Callable[[WebDAVServerExternalSignEventParams], None]) -> None: ...
```

## Remarks

Assign a handler to this event if you need to delegate a low-level signing operation to an external, remote, or custom signing engine. Depending on the settings, the handler will receive a hashed or unhashed value to be signed.

The event handler must pass the value of *Data* to the signer, obtain the signature, and pass it back to the class via the *SignedData* parameter.

*OperationId* provides a comment about the operation and its origin. It depends on the exact class being used, and may be empty. *HashAlgorithm* specifies the hash algorithm being used for the operation, and *Pars* contains algorithm-dependent parameters.

The class uses base16 (hex) encoding for the *Data*, *SignedData*, and *Pars* parameters. If your signing engine uses a different input and output encoding, you may need to decode and/or encode the data before and/or after the signing.

A sample MD5 hash encoded in base16: a0dee2a0382afbb09120ffa7ccd8a152 - lower case base16 A0DEE2A0382AFBB09120FFA7CCD8A152 - upper case base16

A sample event handler that uses the .NET RSACryptoServiceProvider class may look like the following:

```text
signer.OnExternalSign += (s, e) =>
{
       var cert = new X509Certificate2("cert.pfx", "", X509KeyStorageFlags.Exportable);
       var key = (RSACryptoServiceProvider)cert.PrivateKey;

       var dataToSign = e.Data.FromBase16String();
       var signedData = key.SignHash(dataToSign, "2.16.840.1.101.3.4.2.1");
       e.SignedData = signedData.ToBase16String();
};
```

This event, if *OperationStatus* allows, will be followed by a series of [on_write_object](#on_write_object-event) calls, passing object data in chunks, before a [on_upload_object_completed](#on_upload_object_completed-event) call signals completion of the upload operation.

Check the operation status, and alter it, if needed, through the *OperationStatus* parameter:

|  |  |  |
| --- | --- | --- |
| ostOk | 1 |  |
| ostNoSuchFile | 2 |  |
| ostAccessDenied | 3 |  |

# WebDAVServer Config Settings

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

### WebDAVServer Config Settings

**BoundAddress**: Returns the bound address of the listening socket.Use this property to obtain the bound address of the listening socket.

**BoundPort**: The port that was bound by the server.Returns the port number that was bound by the server.

**DualStack**: Allows the use of ip4 and ip6 simultaneously.This setting specifies a socket can use ip4 and ip6 simultaneously.

**HandshakeTimeout**: The HTTPS handshake timeout.The HTTPS handshake timeout in milliseconds.

**Host**: The host to bind to.Specifies a specific interface the server should listen on.

**HTTPStatusCode[i]**: Provides means to set a custom HTTP status code.Use this indexed property to set a custom HTTP status code for a specific client.

**Port**: The port to listen on.This config setting mimics the Port property. Please use that instead.

**PortRangeFrom**: The lower bound of allowed port scope to listen on.Specifies the lowest port number the server may use if dynamic allocation is used.

**PortRangeTo**: The higher bound of allowed port scope to listen on.Specifies the highest port number the server may use if dynamic allocation is used.

**PreSharedIdentityHint**: Gets or sets the PSK identity hint.Use this property to get or set the PSK identity hint to be used during PSK-based TLS handshake.

**SessionTimeout**: The HTTP session timeout.The HTTP session timeout in milliseconds.

**SleepLen**: Adjusts the server loop idling time.Use this property to adjust the server connection loop idling time between consecutive connection read calls. Increasing this setting may help combat excessive CPU usage in performance-restricted or busy environments. Setting it to zero removes the idling altogether, which maximizes the throughput but may cause excessive CPU load.

**TLSCiphersuites**: Returns the list of ciphersuites activated in the component for the current session.Check this property to enumerate the list of TLS ciphersuites enabled in the component. A good place to do that is OnTLSHandshake event handler.

**TLSExtensions**: TBD.TBD

**TLSGroups**: Returns the list of TLS key exchange groups enabled in the component.Check this property to enumerate the list of TLS key exchange groups enabled in the component.

**TLSPeerExtensions**: TBD.TBD

**TLSServerCertIndex**: Specifies the index of the server certificate to use.This setting allows your code to specify the exact certificate/chain to use for the TLS handshake that has just commenced, if your server is configured with more than one chain. This property should typically be adjusted from within the OnTLSHandshake event handler.

Note: the server component normally picks up the most appropriate certificate automatically. This setting is a wiretap for scenarios where unusual or cherry-picked certificate selection logic may be necessary.

**TLSVersions**: Returns the list of TLS versions enabled in the component.Check this property to obtain the list of TLS versions enabled in the component, as an integer bitmask.

**WebsiteName**: The website name for the TLS certificate.Assign this property with a name to put in a self-generated TLS certificate.

### 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 class.

Supported values are:

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

**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 classes 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 classes.

**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 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 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 class is set to "*local*", the property returns/restores the rules from/to the internal storage of the class. If *StaticDNS* of the class is set to "*global*", the property returns/restores the rules from/to the GLOBAL storage. The rules list is returned and accepted in JSON format.

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

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

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

**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.
