Syntax
property IgnoreChainValidationErrors: Boolean read get_IgnoreChainValidationErrors write set_IgnoreChainValidationErrors;
Default Value
false
Remarks

KnownCertificates Property (AuthenticodeVerifier Component)
Additional certificates for chain validation.
Syntax
property KnownCertificates: TsbxCertificateList read get_KnownCertificates write set_KnownCertificates;
Remarks
Use this property to supply a list of additional certificates that might be needed for chain validation. An example of a scenario where you might want to do that is when intermediary CA certificates are absent from the standard system locations (or when there are no standard system locations), and therefore should be supplied to the component manually.
The purpose of certificates to be added to this collection is roughly equivalent to that of Intermediate Certification Authorities system store in Windows.
Do not add trust anchors or root certificates to this collection: add them to TrustedCertificates instead.
This property is not available at design time.
KnownCRLs Property (AuthenticodeVerifier Component)
Additional CRLs for chain validation.
Syntax
property KnownCRLs: TsbxCRLList read get_KnownCRLs write set_KnownCRLs;
Remarks

KnownOCSPs Property (AuthenticodeVerifier Component)
Additional OCSP responses for chain validation.
Syntax
property KnownOCSPs: TsbxOCSPResponseList read get_KnownOCSPs write set_KnownOCSPs;
Remarks
Use this property to supply additional OCSP responses that might be needed for chain validation. This property may be helpful when a chain is validated in offline mode, and the associated OCSP responses are stored separately from the signed message or document.
This property is not available at design time.
OCSPs Property (AuthenticodeVerifier Component)
A collection of OCSP responses embedded into the signature.
Syntax
property OCSPs: TsbxOCSPResponseList read get_OCSPs;
Remarks

OfflineMode Property (AuthenticodeVerifier Component)
Switches the component to the offline mode.
Syntax
property OfflineMode: Boolean read get_OfflineMode write set_OfflineMode;
Default Value
false
Remarks
When working in offline mode, the component restricts itself from using any online revocation information sources, such as CRL or OCSP responders.
Offline mode may be useful if there is a need to verify the completeness of validation information included within the signature or provided via KnownCertificates, KnownCRLs, and other related properties.
Profile Property (AuthenticodeVerifier Component)
Specifies a pre-defined profile to apply when creating the signature.
Syntax
property Profile: String read get_Profile write set_Profile;
Default Value
''
Remarks
Advanced signatures come in many variants, which are often defined by parties that needs to process them or by local standards. SecureBlackbox profiles are sets of pre-defined configurations which correspond to particular signature variants. By specifying a profile, you are pre-configuring the component to make it produce the signature that matches the configuration corresponding to that profile.
Proxy Property (AuthenticodeVerifier Component)
The proxy server settings.
Syntax
property Proxy: TsbxProxySettings read get_Proxy;
Remarks
Use this property to tune up the proxy server settings.
This property is read-only.
RevocationCheck Property (AuthenticodeVerifier Component)
Specifies the kind(s) of revocation check to perform.
Syntax
property RevocationCheck: TsbxRevocationCheckKinds read get_RevocationCheck write set_RevocationCheck;
TsbxRevocationCheckKinds = ( crcNone, crcAuto, crcAllCRL, crcAllOCSP, crcAllCRLAndOCSP, crcAnyCRL, crcAnyOCSP, crcAnyCRLOrOCSP, crcAnyOCSPOrCRL );
Default Value
crcAuto
Remarks
Revocation checking is necessary to ensure the integrity of the chain and obtain up-to-date certificate validity and trustworthiness information.
Certificate Revocation Lists (CRL) and Online Certificate Status Protocol (OCSP) responses serve the same purpose of ensuring that the certificate had not been revoked by the Certificate Authority (CA) at the time of use. Depending on your circumstances and security policy requirements, you may want to use either one or both of the revocation information source types.
| crcNone (0) | No revocation checking |
| crcAuto (1) | Automatic mode selection. Currently this maps to crcAnyOCSPOrCRL, but it may change in the future. |
| crcAllCRL (2) | Check all provided CRL endpoints for all chain certificates. |
| crcAllOCSP (3) | Check all provided OCSP endpoints for all chain certificates. |
| crcAllCRLAndOCSP (4) | Check all CRL and OCSP endpoints for all chain certificates. |
| crcAnyCRL (5) | At least one CRL check for every certificate in the chain must succeed. |
| crcAnyOCSP (6) | At least one OCSP check for every certificate in the chain must succeed. |
| crcAnyCRLOrOCSP (7) | At least one CRL or OCSP check for every certificate in the chain must succeed. CRL endpoints are checked first. |
| crcAnyOCSPOrCRL (8) | At least one CRL or OCSP check for every certificate in the chain must succeed. OCSP endpoints are checked first. |
This setting controls the way the revocation checks are performed. 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 faster OCSP route and only demand one source to succeed) is a good choice for most of typical validation environments. The 'crcAll*' modes are much stricter, and may be used in scenarios where bulletproof validity information is essential.

property TrustedCertificates: TsbxCertificateList read get_TrustedCertificates write set_TrustedCertificates;
Remarks
Use this property to supply a list of trusted certificates that might be needed for chain validation. An example of a scenario where you might want to do that is when root CA certificates are absent from the standard system locations (or when there are no standard system locations), and therefore should be supplied to the component manually.
The purpose of this certificate collection is largely the same than that of Windows Trusted Root Certification Authorities system store.
Use this property with extreme care as it directly affects chain verifiability; a wrong certificate added to the trusted list may result in bad chains being accepted, and forfeited signatures being recognized as genuine. Only add certificates that originate from the parties that you know and trust.

The time point at which signature validity is to be established.
Syntax
property ValidationMoment: String read get_ValidationMoment write set_ValidationMoment;
Default Value
''
Remarks
Use this property to specify the moment in time at which signature validity should be established. The time is in UTC. Leave the setting empty to stick to the default moment (either signature creation time, or current time).
The validity of the same signature may differ depending on the time point chosen due to temporal changes in chain validities, revocation statuses, and timestamp times.
Config Method (AuthenticodeVerifier Component)
Sets or retrieves a configuration setting.
Syntax
function Config(ConfigurationString: String): String;
Remarks
Config is a generic method available in every component. It is used to set and retrieve configuration settings for the component.
These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, 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.
DoAction Method (AuthenticodeVerifier Component)

|
RevocationCheck TsbxRevocationCheckKinds |
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.
This setting controls the way the revocation checks are performed. 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 faster OCSP route and only demand one source to succeed) is a good choice for most of typical validation environments. The 'crcAll*' modes are much stricter, and may be used in scenarios where bulletproof validity information is essential. |

Config Settings (AuthenticodeVerifier Component)
The component 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 component, access to these internal properties is provided through the Config method.AuthenticodeVerifier Config Settings | ||||||||||||||||||||||||||||||
| BufferSize: Specifies buffer size in bytes.Use this property to set the buffer size (in bytes) that should be used when processing binaries. The default value is 1048576 (1 MB). | ||||||||||||||||||||||||||||||
| DislikeOpenEndedOCSPs: Tells the component to discourage OCSP responses without an explicit NextUpdate parameter.When this property is set to True, the validation engine treats OCSP response without a NextUpdate field as 'substandard' and tries to obtain some further revocation material for the certificate in question (a different OCSP or a CRL, even if the component is configured to prefer the OCSP route). This is to work around Adobe Reader's intolerance to such OCSPs when classifying signed documents as LTV (as of August 2022). | ||||||||||||||||||||||||||||||
| ForceCompleteChainValidationForTrusted: Whether to continue with the full validation up to the root CA certificate for mid-level trust anchors. Set this property to True to enable full chain validation for explicitly trusted intermediary or end-entity certificates. This may be useful when creating signatures to enforce completeness of the collected revocation information. It often makes sense to set this property to false when validating signatures to reduce validation time and avoid issues with badly configured environments. | ||||||||||||||||||||||||||||||
| GracePeriod: Specifies a grace period to apply during revocation information checks.Use this property to specify a grace period (in seconds). Grace period applies to certain subprotocols, such as OCSP, and caters to the inaccuracy and/or missynchronization of clocks on different participating systems. Any time deviations within the grace period will be tolerated. | ||||||||||||||||||||||||||||||
| IgnoreChainLoops: Whether chain loops should be ignored.Set this property to True to make the validation engine ignore chain loops. This may be an option when you need to process chains from buggy CAs that happen to include subchains that sign themselves. | ||||||||||||||||||||||||||||||
| IgnoreOCSPNoCheckExtension: Whether OCSP NoCheck extension should be ignored.Set this property to True to make the validation engine ignore the OCSP no-check extension. You would normally need to set this property when validating severely non-compliant chains that misuse the extension, causing chain loops or other validation issues. | ||||||||||||||||||||||||||||||
| IgnoreSystemTrust:
Whether trusted Windows Certificate Stores should be treated as trusted.Specifies whether, during chain validation, the component should respect
the trust to CA certificates as configured in the operating system.
In Windows this effectively defines whether the component should trust the
certificates residing in the Trusted Root Certification Authorities store.
If IgnoreSystemTrust is True, certificates residing in the trusted root store are treated as if they are known, rather than trusted. Only certificates provided via other means (such as TrustedCertificates property) are considered trusted. |
||||||||||||||||||||||||||||||
| ImplicitlyTrustSelfSignedCertificates: Whether to trust self-signed certificates. Set this property to True to implicitly trust all self-signed certificates. Use it with care as trusting just about every self-signed certificate is unwise. One exceptional reason where this property may be handy is where a chain is validated in an environment that is not supposed to trust it (for example, a signing, rather than verifying environment, or a QA server). Trusting all self-signing certificates (which are normally trusted) allows to emulate the verifying environment without actually changing its security settings. | ||||||||||||||||||||||||||||||
| PromoteLongOCSPResponses: Whether long OCSP responses are requested. Set this property to True to force the component to publish 'long' form of OCSP responses. Otherwise, only BasicOCSPResponse blobs are promoted. | ||||||||||||||||||||||||||||||
| TempPath: Path for storing temporary files.This setting specifies an absolute path to the location on disk where temporary files are stored. | ||||||||||||||||||||||||||||||
TolerateMinorChainIssues:
Whether to tolerate minor chain issues.This parameter controls whether the chain validator should tolerate minor technical issues when validating the chain. Those are:
|
||||||||||||||||||||||||||||||
| UseMicrosoftCTL: Enables or disables automatic use of Microsoft online certificate trust list.Enable this property to make the chain validation module automatically look up missing CA certificates in the public Windows Update repository. | ||||||||||||||||||||||||||||||
| UseSystemCertificates: Enables or disables the use of the system certificates.Use this property to tell chain validation module automatically look up missing CA certificates in the system certificates. In many cases it is beneficial to switch this property on, as the operating system certificate configuration provides a representative trust framework. | ||||||||||||||||||||||||||||||
| UseValidationCache: Enables or disable the use of the product-wide certificate chain validation cache.Use this property to enable or disable the use of the global chain validation cache. If enabled, the component will consult the product-wide validation cache when validating the signing chains. Also, the outcomes of any new chain validations performed by the component, both interim and final, will be saved in the cache and available for re-use by any future validations. Disable this property to ignore the cache and always perform the validation from the fresh start. | ||||||||||||||||||||||||||||||
Base Config Settings | ||||||||||||||||||||||||||||||
| 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 component.
Supported values are:
|
||||||||||||||||||||||||||||||
| Cookies: Gets or sets local cookies for the component (supported for HTTPClient, RESTClient and SOAPClient only).Use this property to get cookies from the internal cookie storage of the component 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. | ||||||||||||||||||||||||||||||
| 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. |
||||||||||||||||||||||||||||||
| 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 components that have its CookieCaching property set to "global". | ||||||||||||||||||||||||||||||
| 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 components. | ||||||||||||||||||||||||||||||
| LogDestination:
Specifies the debug log destination.Contains a comma-separated list of values that specifies where debug log should be dumped.
Supported values are:
|
||||||||||||||||||||||||||||||
| 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:
|
||||||||||||||||||||||||||||||
| 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:
|
||||||||||||||||||||||||||||||
LogFlushMode:
Specifies the log flush mode.Use this property to set the log flush mode. The following values are defined:
|
||||||||||||||||||||||||||||||
| LogLevel:
Specifies the debug log level.Use this property to provide the desired debug log level.
Supported values are:
|
||||||||||||||||||||||||||||||
| 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:
|
||||||||||||||||||||||||||||||
| 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. | ||||||||||||||||||||||||||||||
| Tag: Allows to store any custom data.Use this config property to store any custom data. | ||||||||||||||||||||||||||||||
| 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. | ||||||||||||||||||||||||||||||
| 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. |
