# Struct secureblackbox::PGPKeyManager The PGPKeyManager struct manages individual PGP keys. ## Syntax ```text secureblackbox::PGPKeyManager ``` ## Remarks PGPKeyManager provides means for generating, checking, and editing individual PGP keys. PGPKeyManager can work with RSA, Elgamal (DH), ECDSA, DSS, and EdDSA keypairs with or without subkeys. Public and private PGP keys of versions 2, 3, 4, 5, and 6 are supported. Note: if you are looking to work with multi-key files ('keyrings'), please see the [PGPKeyring](PGPKeyring.md#PGPKeyring) component instead. PGPKeyManager works with individual PGP key structures ('key trees' - one primary key with subkeys). For that same reason, consider using [PGPKeyring](PGPKeyring.md#PGPKeyring) for loading keys that are to be used with [PGPWriter](PGPWriter.md#PGPWriter) and [PGPReader](PGPReader.md#PGPReader) for signing or encryption. It is often the case that even allegedly single-key files actually contain more than one key tree, which may lead to key material loss if they are loaded into PGPKeyManager. Or, putting it in a simple way: - Use PGPKeyManager if you need to *alter* a key (e.g. generate, add or remove subkeys, revoke, re-sign, change password). - Where you need to *use* an existing key (e.g. for signing), use [PGPKeyring](PGPKeyring.md#PGPKeyring), even if it is a standalone key. - To alter a key residing in a keyring, load the keyring files into [PGPKeyring](PGPKeyring.md#PGPKeyring) first. The assign the key in question to PGPKeyManager, make the necessary changes, return it back to the keyring, and re-save the keyring. You can load keys into a PGPKeyManager object in one of the following ways: - By loading it from a file or memory using [import_from_file](#import_from_file-method-pgpkeymanager-struct) or [import_bytes](#import_bytes-method-pgpkeymanager-struct) methods. - By importing it from a PGPKeyring object using [import_pinned](#import_pinned-method-pgpkeymanager-struct) method. - By generating it using [generate_pair](#generate_pair-method-pgpkeymanager-struct) or [create_key](#create_key-method-pgpkeymanager-struct) methods. ```text Mgr.ImportFromFile("key.pub"); ``` Once you have the key loaded in your PGPKeyManager object, you can perform a variety of operations on it: - Iterate over elements of the key tree using subkeys, signatures, and users collections. - Add new subkeys to it using [create_subkey](#create_subkey-method-pgpkeymanager-struct) method. Note that your new subkey is unlikely to be accepted elsewhere unless you sign it. - Add new user records to the key with [create_user](#create_user-method-pgpkeymanager-struct) method. - Signing keys, subkeys, and user records (existing or new) with this or another private key using [sign_key](#sign_key-method-pgpkeymanager-struct), [sign_subkey](#sign_subkey-method-pgpkeymanager-struct), and [sign_user](#sign_user-method-pgpkeymanager-struct) methods. The new signatures are added to the key tree. - Remove or revoke existing subkeys, user records, and signatures. - Change the key protection level or password. Note: Use pinning to copy keys between PGPKeyring and PGPKeyManager: ```text Keyring.PinnedKey = Mgr.Key; Keyring.ImportPinned(); Mgr.PinnedKey = Keyring.SelectedKeys[i]; Mgr.ImportPinned(); ``` Once your work with the key tree has completed, save it to a buffer or file using [export_bytes](#export_bytes-method-pgpkeymanager-struct) and [export_to_file](#export_to_file-method-pgpkeymanager-struct) methods. ### 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 PGPKeyManager struct cannot be disposed of automatically. Please, call the *dispose(&mut; self)* method of PGPKeyManager when you have finished using the instance. ## Property List *The following is the full list of the properties of the struct with short descriptions.

While it is typical to sign user IDs with their own secret keys, occasionally third-party authentication is used where the binding is signed with a third-party key. The *KeyValidTo* parameter indicates the expiration date of the binding. It can be different to that of the signing and/or the main key. The *Primary* parameter indicates whether this should be considered the primary user ID for this key (for example, if the user has more than one email). The *CertType* parameters indicates the type of binding, and should be set to one of the following values (if unsure, use pctGeneric): | | | | | --- | --- | --- | | pctGeneric | 0 | Generic certification of a User ID and Public Key packet. The issuer of this certification does not make any particular assertion as to how well the certifier has checked that the owner of the key is in fact the person described by the User ID. By default user certifications use Generic type. | | pctPersona | 1 | Persona certification of a User ID and Public Key packet. The issuer of this certification has not done any verification of the claim that the owner of this key corresponds to the specified User ID. | | pctCasual | 2 | Casual certification of a User ID and a Public Key packet. The issuer of this certification has done some casual verification of the claim of identity. | | pctPositive | 3 | Positive certification of a User ID and a Public Key packet. The issuer of this certification has done substantial verification of the claim of identity. | # verify method ([PGPKeyManager](#struct-secureblackboxpgpkeymanager) Struct) Verifies the integrity of a key signature. ## Syntax *Rust Syntax* ```text fn verify(&self, index : i32) -> Result ``` ## Remarks Use this method to validate a key signature. Provide the index of the signature as a parameter. # on_error event ([PGPKeyManager](#struct-secureblackboxpgpkeymanager) Struct) Information about errors during PGP key management. ## Syntax *Rust Syntax* ```text // PGPKeyManagerErrorEventArgs carries the PGPKeyManager Error event's parameters. pub struct PGPKeyManagerErrorEventArgs { fn error_code(&self) -> i32 fn description(&self) -> &String } // PGPKeyManagerErrorEvent defines the signature of the PGPKeyManager Error event's handler function. pub trait PGPKeyManagerErrorEvent { fn on_error(&self, sender : PGPKeyManager, e : &mut PGPKeyManagerErrorEventArgs); } impl <'a> PGPKeyManager<'a> { pub fn on_error(&self) -> &'a dyn PGPKeyManagerErrorEvent; pub fn set_on_error(&mut self, value : &'a dyn PGPKeyManagerErrorEvent); ... } ``` ## Remarks The event is fired in case of exceptional conditions during key management. *ErrorCode* contains an error code and *Description* contains a textual description of the error. # on_key_passphrase_needed event ([PGPKeyManager](#struct-secureblackboxpgpkeymanager) Struct) Requests a key protection password from the application. ## Syntax *Rust Syntax* ```text // PGPKeyManagerKeyPassphraseNeededEventArgs carries the PGPKeyManager KeyPassphraseNeeded event's parameters. pub struct PGPKeyManagerKeyPassphraseNeededEventArgs { fn key_id(&self) -> &String fn user_id(&self) -> &String fn main_key(&self) -> bool fn passphrase(&self) -> &String fn set_passphrase(&self, value : &str) fn set_passphrase_ref(&self, value : &String) fn skip(&self) -> bool fn set_skip(&self, value : bool) } // PGPKeyManagerKeyPassphraseNeededEvent defines the signature of the PGPKeyManager KeyPassphraseNeeded event's handler function. pub trait PGPKeyManagerKeyPassphraseNeededEvent { fn on_key_passphrase_needed(&self, sender : PGPKeyManager, e : &mut PGPKeyManagerKeyPassphraseNeededEventArgs); } impl <'a> PGPKeyManager<'a> { pub fn on_key_passphrase_needed(&self) -> &'a dyn PGPKeyManagerKeyPassphraseNeededEvent; pub fn set_on_key_passphrase_needed(&mut self, value : &'a dyn PGPKeyManagerKeyPassphraseNeededEvent); ... } ``` ## Remarks The struct fires this event to request a secret key passphrase from the application. Note that this event asks for a key protection passphrase rather than a message protection passphrase. The struct fires it when it attempts to use a secret key to sign the data. This event is fired for every protected secret key residing in signing_keys. *KeyID* specifies the key for which the password is requested, and *UserID* identifies its user. *MainKey* tells whether the key is a master key or a subkey. The handler should provide password via the *Passphrase* parameter, or set *Skip* to True to skip this key. For each key *KeyPassphraseNeeded* is called in a loop until the correct password is provided or the maximum number of password attempts reached. # on_notification event ([PGPKeyManager](#struct-secureblackboxpgpkeymanager) Struct) This event notifies the application about an underlying control flow event. ## Syntax *Rust Syntax* ```text // PGPKeyManagerNotificationEventArgs carries the PGPKeyManager Notification event's parameters. pub struct PGPKeyManagerNotificationEventArgs { fn event_id(&self) -> &String fn event_param(&self) -> &String } // PGPKeyManagerNotificationEvent defines the signature of the PGPKeyManager Notification event's handler function. pub trait PGPKeyManagerNotificationEvent { fn on_notification(&self, sender : PGPKeyManager, e : &mut PGPKeyManagerNotificationEventArgs); } impl <'a> PGPKeyManager<'a> { pub fn on_notification(&self) -> &'a dyn PGPKeyManagerNotificationEvent; pub fn set_on_notification(&mut self, value : &'a dyn PGPKeyManagerNotificationEvent); ... } ``` ## Remarks The struct fires this event to let the application know about some event, occurrence, or milestone in the struct. For example, it may fire to report completion of the document processing. The list of events being reported is not fixed, and may be flexibly extended over time. The unique identifier of the event is provided in the *EventID* parameter. *EventParam* contains any parameters accompanying the occurrence. Depending on the type of the struct, the exact action it is performing, or the document being processed, one or both may be omitted. # Config Settings ([PGPKeyManager](#struct-secureblackboxpgpkeymanager) 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-pgpkeymanager-struct) method. ### PGPKeyManager Config Settings **Armor**: Enables or disables ASCII armouring.Adjust this setting to enable or disable ASCII armouring on the outgoing messages. **ArmorBoundary**: Specifies the armour boundary/title.Use this setting to specify custom ASCII armouring titles that go after the -----BEGIN and -----END tokens. **ArmorHeaders**: Specifies armour headers.Use this setting to provide custom ASCII armouring (PEM) headers that should be included in the output. **HashAlgorithm**: The hash algorithm to use with the operation, when not accepted via a parameter.This configuration setting lets you specify the hash algorithm to be used with an operation that does not accept it via a method parameter. **KeyFlags**: Specifies key flags for user certification signatures.Use this setting to pass a bit mask of key flags to the user certification signature: | | | | | --- | --- | --- | | KeyFlagCertifyOtherKeys | 1 | The key can certify other keys | | KeyFlagSignData | 2 | The key can be used to sign data | | KeyFlagEncryptData | 4 | The key can be used to encrypt data (in transit) | | KeyFlagEncryptStorage | 8 | The key can be used to encrypt data (at rest) | | KeyFlagSplitKey | 16 | The key is part of a split key scheme | | KeyFlagGroupKey | 32 | The key is part of a group key scheme | Use this property before calling the [sign_user](#sign_user-method-pgpkeymanager-struct) method. The config setting is cleared after each signing operation. **KeyHashAlgorithm**: The hash algorithm associated with the key.This setting returns the hash algorithm associated with and inherent to the key (such as SHA1 for DSA keys, or SHA512 for EdDSA keys) **PreferredAlgs**: Specifies preferred algorithms for user certification signatures.Use this setting to include a list of preferred algorithms in the certification signature. The algorithms may include symmetric, hash, and compression algorithms. Example: AES256,SHA256,AES128,SHA512,ZIP,ZLIB,CAST5 **RawKeyFormat**: Specifies whether low-level key format should be used as input or output of an operation.This setting specifies whether to use the raw (low-level, such as PKCS#1) key format during import or export operation. **RespectKeyUsage**: Enables policy-based key usage checks.Set this property to true to enable policy-based key usage checks. If set to false (the default value), the values of CanSign and CanEncrypt properties of the key objects are based on the underlying cryptographic algorithm capabilities only. If switched to true, the values of the properties also consider the content of the key flags extension included in the respective key signatures. **SaveKeyTrust**: Tells the component to include the trust packets with the serialized keys.Enables or disables inclusion of trust markers in the output keyring files. The default value is true. **SaveSecretKeySignatures**: Enforces saving of signature packets to the secret keyring file.By default, key binding and user ID signatures are saved with the public part of the PGP keyring, whereas the private part only contains the secret key material. Set this option to true to enforce saving of signatures alongside the private keys. This may be useful when storing the keyring as a single file instead of a public/private pair. **SignatureCreationTime**: Indicates the signature creation time.Returns the signature creation time. **SignatureExpirationTime**: Returns or sets the signature expiration time.Returns the signature expiration time. **SignatureHashAlgorithm**: The hash algorithm of the signature.Use this setting to obtain the hash algorithm of the signature. **SubkeyIndex**: Allows to select a specific subkey for certain operations.It is typical for PGP key trees to employ the same protection parameters and passwords for all the keys and subkeys contained in the tree. This config setting lets you select a specific subkey if you want to apply certain protection parameter exclusively to that subkey. For example, the following code will only change the passphrase on the subkey with the index of 2: ```text mgr.Config("SubkeyIndex=2"); mgr.ChangePassphrase("oldpass", "newpass"); ``` Note: set this property to -2 to apply the setting to the main key. The default value of -1 indicates that any protection operation applies to all keys and subkeys in the tree. **UseLongKeyIDs**: Use full-length KeyID format.It is typical for implementations to use the lower 4 bytes of PGP key IDs. Set this property to true to switch to the full (8-byte) key ID format. ### 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 | | systemlog | | System Log (supported for Android only) | | debugger | | Debugger (supported for VCL for Windows and .Net) | **LogDetails**: Specifies the debug log details to dump.Contains a comma-separated list of values that specifies which debug log details to dump. Supported values are: | | | | | --- | --- | --- | | time | | Current time | | level | | Level | | package | | Package name | | module | | Module name | | class | | Class name | | method | | Method name | | threadid | | Thread Id | | contenttype | | Content type | | content | | Content | | all | | All details | **LogFile**: Specifies the debug log filename.Use this property to provide a path to the log file. **LogFilters**: Specifies the debug log filters.Contains a comma-separated list of value pairs ("name:value") that describe filters. Supported filter names are: | | | | | --- | --- | --- | | exclude-package | | Exclude a package specified in the value | | exclude-module | | Exclude a module specified in the value | | exclude-class | | Exclude a class specified in the value | | exclude-method | | Exclude a method specified in the value | | include-package | | Include a package specified in the value | | include-module | | Include a module specified in the value | | include-class | | Include a class specified in the value | | include-method | | Include a method specified in the value | **LogFlushMode**: Specifies the log flush mode.Use this property to set the log flush mode. The following values are defined: | | | | | --- | --- | --- | | none | | No flush (caching only) | | immediate | | Immediate flush (real-time logging) | | maxcount | | Flush cached entries upon reaching LogMaxEventCount entries in the cache. | **LogLevel**: Specifies the debug log level.Use this property to provide the desired debug log level. Supported values are: | | | | | --- | --- | --- | | none | | None (by default) | | fatal | | Severe errors that cause premature termination. | | error | | Other runtime errors or unexpected conditions. | | warning | | Use of deprecated APIs, poor use of API, 'almost' errors, other runtime situations that are undesirable or unexpected, but not necessarily "wrong". | | info | | Interesting runtime events (startup/shutdown). | | debug | | Detailed information on flow of through the system. | | trace | | More detailed information. | **LogMaxEventCount**: Specifies the maximum number of events to cache before further action is taken.Use this property to specify the log event number threshold. This threshold may have different effects, depending on the rotation setting and/or the flush mode. The default value of this setting is 100. **LogRotationMode**: Specifies the log rotation mode.Use this property to set the log rotation mode. The following values are defined: | | | | | --- | --- | --- | | none | | No rotation | | deleteolder | | Delete older entries from the cache upon reaching LogMaxEventCount | | keepolder | | Keep older entries in the cache upon reaching LogMaxEventCount (newer entries are discarded) | **MaxASN1BufferLength**: Specifies the maximal allowed length for ASN.1 primitive tag data.This global property limits the maximal allowed length for ASN.1 tag data for non-content-carrying structures, such as certificates, CRLs, or timestamps. It does not affect structures that can carry content, such as CMS/CAdES messages. This is a security property aiming at preventing DoS attacks. **MaxASN1TreeDepth**: Specifies the maximal depth for processed ASN.1 trees.This global property limits the maximal depth of ASN.1 trees that the component can handle without throwing an error. This is a security property aiming at preventing DoS attacks. **OCSPHashAlgorithm**: Specifies the hash algorithm to be used to identify certificates in OCSP requests.This global setting defines the hash algorithm to use in OCSP requests during chain validation. Some OCSP responders can only use older algorithms, in which case setting this property to SHA1 may be helpful. **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. # Trappable Errors ([PGPKeyManager](#struct-secureblackboxpgpkeymanager) Struct) ### PGPKeyManager Errors | | | | --- | --- | | 1048577 | Invalid parameter ([SB_ERROR_INVALID_PARAMETER](constants.md#const_SBERRORINVALIDPARAMETER)) | | 1048578 | Invalid configuration ([SB_ERROR_INVALID_SETUP](constants.md#const_SBERRORINVALIDSETUP)) | | 1048579 | Invalid state ([SB_ERROR_INVALID_STATE](constants.md#const_SBERRORINVALIDSTATE)) | | 1048580 | Invalid value ([SB_ERROR_INVALID_VALUE](constants.md#const_SBERRORINVALIDVALUE)) | | 1048581 | Private key not found ([SB_ERROR_NO_PRIVATE_KEY](constants.md#const_SBERRORNOPRIVATEKEY)) | | 1048582 | Cancelled by the user ([SB_ERROR_CANCELLED_BY_USER](constants.md#const_SBERRORCANCELLEDBYUSER)) | | 1048583 | The file was not found ([SB_ERROR_NO_SUCH_FILE](constants.md#const_SBERRORNOSUCHFILE)) | | 1048584 | Unsupported feature or operation ([SB_ERROR_UNSUPPORTED_FEATURE](constants.md#const_SBERRORUNSUPPORTEDFEATURE)) | | 1048585 | General error ([SB_ERROR_GENERAL_ERROR](constants.md#const_SBERRORGENERALERROR)) | | 27262977 | The file was not found ([SB_ERROR_PGP_FILE_NOT_EXISTS](constants.md#const_SBERRORPGPFILENOTEXISTS)) | | 27262978 | Invalid signing key ([SB_ERROR_PGP_INVALID_KEY](constants.md#const_SBERRORPGPINVALIDKEY)) | | 27262980 | No secret key is available ([SB_ERROR_PGP_NO_SECRET_KEY](constants.md#const_SBERRORPGPNOSECRETKEY)) | | 27262982 | The operation is not supported on a subkey ([SB_ERROR_PGP_OPERATION_ON_SUBKEY](constants.md#const_SBERRORPGPOPERATIONONSUBKEY)) |
