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

Syntax

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.

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 struct, the exact action it is performing, or the document being processed, one or both may be omitted.

Config Settings (XMLEncryptor 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 method.

XMLEncryptor Config Settings

EncryptedDataID: Specifies the ID for EncryptedData element.

This property contains the identifier (ID) attribute of the xenc:EncryptedData element.

EncryptedKeyID: Specifies the ID for EncryptedKey element.

This property contains the identifier (ID) attribute of the xenc:EncryptedKey element.

EncryptedKeyInfoCustomXML: The custom XML content for EncryptedKey\KeyInfo element.

Use this property to specify the custom XML content of the xenc:EncryptedKey\ds:KeyInfo element.

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

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

EncryptedKeyInfoID: Specifies the ID for EncryptedKey\KeyInfo element.

This property contains the identifier (ID) attribute of the xenc:EncryptedKey\ds:KeyInfo element.

EncryptedKeyOnly: Specifies whether to create only EncryptedKey element.

Set this property to True to create only xenc:EncryptedKey element.

EncryptedKeyXMLElement: Specifies the XML element where to save the encrypted key element.

This property specifies the XML element where to save the xenc:EncryptedKey element.

Supported values are:


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

EncryptionPrefix: Specifies the encryption prefix.

Specifies the prefix for the EncryptedData elements.

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

Special values:


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

KeyInfoCustomXML: The custom XML content for KeyInfo element.

Use this property to specify the custom XML content of the ds:KeyInfo element.

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

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

KeyInfoID: Specifies the ID for KeyInfo element.

This property contains the identifier (ID) attribute of the ds:KeyInfo element.

KeyName: Contains information about the key used for encryption.

The KeyName element contains a string value (with significant whitespaces) which may be used by the encryptor to communicate a key identifier to the recipient. Typically, the KeyName element contains an identifier related to the key pair used to sign the message, but it may contain other protocol-related information that indirectly identifies a key pair. Common uses of the KeyName include simple string names for keys, a key index, a distinguished name (DN), an email address, etc.

MimeType: Specifies the mime type of the encrypted data.

MimeType is an optional (advisory) attribute which describes the media type of the data which is encrypted. The value of this attribute is a string with values defined by MIME specification (RFC 2045). For example, if the data that is encrypted is a base64 encoded PNG, the transfer Encoding may be specified as 'http://www.w3.org/2000/09/xmldsig#base64' and the MimeType as 'image/png'. This attribute is purely advisory; no validation of the MimeType information is required and it does not indicate the encryption application must do any additional processing.

SignaturePrefix: Specifies the signature prefix.

Specifies the prefix for the Signature elements.

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

Special values:


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

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, where this limitation does not apply.

WriteBOM: Specifies whether byte-order mark should be written when saving the document.

Set this property to False to disable writing byte-order mark (BOM) when saving the XML document in Unicode encoding.

XMLFormatting: Specifies the signature XML formatting.

Use this property to specify how the signature should be formatted.

Supported values:


"" or "none"		no formatting (by default).
"auto"		enables auto-formatting, equivalent to: "indent: 1; indent-char: tab; base64-max-length: 64; starting-level: node"

Custom values, contains a list of value pairs ("name:value") separated by comma or semicolon:


indent		specifies indentation level (default is 1)
indent-char		specifies indentation character: "space" or "tab" (default)
base64-max-length		specifies max length of base64 encoded data, such as signature value, certificate data and etc. (default is 64)
starting-level		specifies starting indentation level: non-negative integer or "node" - detected based on parent node, or "root" - detected based on number of parent nodes to a document element (default is "node").
indent-before-main		specifies if whitespace characters should be inserted before a main (ds:Signature) element: "auto" (default), "yes" or "no"

For more precise formatting use OnFormatText and OnFormatElement events.

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.

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): 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: 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: 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: Config("XMLRDNDescriptorName[2.5.4.5]=SERIALNUMBER");

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