OutputBytes Property (CAdESVerifier Component)

Use this property to read the output the component object has produced.

Syntax

public byte[] OutputBytes { get; }
Public ReadOnly Property OutputBytes As Byte()

Remarks

Syntax

public string Profile { get; set; }
Public Property Profile As String

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 (CAdESVerifier Component)

The proxy server settings.

Syntax

public ProxySettings Proxy { get; }
Public ReadOnly Property Proxy As ProxySettings

Remarks

Use this property to tune up the proxy server settings.

Syntax

public CadesverifierRevocationChecks RevocationCheck { get; set; }

enum CadesverifierRevocationChecks { crcNone, crcAuto, crcAllCRL, crcAllOCSP, crcAllCRLAndOCSP, crcAnyCRL, crcAnyOCSP, crcAnyCRLOrOCSP, crcAnyOCSPOrCRL }
Public Property RevocationCheck As CadesverifierRevocationChecks

Enum CadesverifierRevocationChecks crcNone crcAuto crcAllCRL crcAllOCSP crcAllCRLAndOCSP crcAnyCRL crcAnyOCSP crcAnyCRLOrOCSP crcAnyOCSPOrCRL End Enum

Default Value

1

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and Online Certificate Status Protocol (OCSP) responses serve the same purpose of ensuring that the certificate had not been revoked by the Certificate Authority (CA) at the time of use.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.

crcNone0No revocation checking
crcAuto1Automatic mode selection. Currently this maps to crcAnyOCSPOrCRL, but it may change in the future.
crcAllCRL2Check all provided CRL endpoints for all chain certificates.
crcAllOCSP3Check all provided OCSP endpoints for all chain certificates.
crcAllCRLAndOCSP4Check all CRL and OCSP endpoints for all chain certificates.
crcAnyCRL5At least one CRL check for every certificate in the chain must succeed.
crcAnyOCSP6At least one OCSP check for every certificate in the chain must succeed.
crcAnyCRLOrOCSP7At least one CRL or OCSP check for every certificate in the chain must succeed. CRL endpoints are checked first.
crcAnyOCSPOrCRL8At 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.

Signature Property (CAdESVerifier Component)

The signature that is currently being processed.

Syntax

public CAdESSignature Signature { get; }
Public ReadOnly Property Signature As CAdESSignature

Remarks

Use this property to access the fields of the signature that is currently being processed. This field also keeps information about the last processed signature after the completion of the Verify method.

This property is read-only and not available at design time.

Please refer to the CAdESSignature type for a complete list of fields.

SignedAttributes Property (CAdESVerifier Component)

Custom signature attributes that are covered by the electronic signature.

Syntax

public SignatureAttributeList SignedAttributes { get; }
Public ReadOnly Property SignedAttributes As SignatureAttributeList

Please refer to the TLSSettings type for a complete list of fields.

TrustedCertificates Property (CAdESVerifier Component)

A list of trusted certificates for chain validation.

Syntax

public CertificateList TrustedCertificates { get; }
Public Property TrustedCertificates As CertificateList

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.

This property is not available at design time.

Please refer to the Certificate type for a complete list of fields.

TSACertificate Property (CAdESVerifier Component)

Remarks

Signature attributes are used to store auxiliary information in the signature. Values included as unsigned attributes are not covered by the signature and can be changed or removed without affecting the signature.

This property is read-only and not available at design time.

Please refer to the SignatureAttribute type for a complete list of fields.

ValidationMoment Property (CAdESVerifier Component)

The time point at which signature validity is to be established.

Syntax

public string ValidationMoment { get; set; }
Public Property ValidationMoment As String

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 (CAdESVerifier Component)

Sets or retrieves a configuration setting.

Syntax

public string Config(string configurationString);
Public Function Config(ByVal ConfigurationString As String) As 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 (CAdESVerifier Component)

Performs an additional action.

Syntax

public string DoAction(string actionID, string actionParams);
Public Function DoAction(ByVal ActionID As String, ByVal ActionParams As String) As String

Remarks

DoAction is a generic method available in every component. 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 insencitive) 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;....

Verify Method (CAdESVerifier Component)

Verifies a digitally signed CAdES message.

Syntax

public void Verify();
Public Sub Verify()

Remarks

CAdESVerifier supports two types of signatures: enveloping and detached. In the enveloping case, both the data and the signature travel in the same 'combined' message. The detached variant observes the signature and the data (in its original form) residing in different files.

Call this method to verify enveloping signatures provided via InputStream or InputFile property, and extract the embedded data to OutputFile or OutputStream. Use VerifyDetached to verify detached signatures.

VerifyDetached Method (CAdESVerifier Component)

Verifies a detached CAdES signature.

Syntax

public void VerifyDetached();
Public Sub VerifyDetached()

Remarks

Use this method to verify detached signatures. Pass the signature via InputStream or InputFile property, and the data via DataStream or DataFile property.

Use Verify to verify enveloping (non-detached) signatures.

ChainElementDownload Event (CAdESVerifier Component)

Fires when there is a need to download a chain element from an online source.

Syntax

public event OnChainElementDownloadHandler OnChainElementDownload;

public delegate void OnChainElementDownloadHandler(object sender, CadesverifierChainElementDownloadEventArgs e);

  Public ReadOnly Property Kind As Integer
  Public ReadOnly Property CertRDN As String
  Public ReadOnly Property CACertRDN As String
  Public ReadOnly Property Location As String
  Public Property Action As Integer
End Class

Remarks

Subscribe to this event to be notified about validation element retrievals. Use Action parameter to suppress the download if required.

veaAuto0Handle the action automatically (the default behaviour)

veaContinue1Accept the request implied by the event (accept the certificate, allow the object retrieval)

veaReject2Reject the request implied by the event (reject the certificate, disallow the object retrieval)

veaAcceptNow3Accept the validated certificate immediately

veaAbortNow4Abort the validation, reject the certificate

ChainElementNeeded Event (CAdESVerifier Component)

Fires when an element required to validate the chain was not located.

Syntax

public event OnChainElementNeededHandler OnChainElementNeeded;

public delegate void OnChainElementNeededHandler(object sender, CadesverifierChainElementNeededEventArgs e);

public class CadesverifierChainElementNeededEventArgs : EventArgs {
  public int Kind { get; }
  public string CertRDN { get; }
  public string CACertRDN { get; }
}

Scope
int (read-only)

Default Value: 0

Returns the type of the entity that this signature corresponds to.

A CAdES signature may cover several kinds of entities: the signed data itself (a top-level signature - something you create when you sign documents), a timestamp, or a countersignature.

cssUnknown0The scope of signature is unknown

cssData1The signature is a top-level signature over the data

cssSignature2The signature is a countersignature, and is made over another signature

cssTimestamp3The signature is made over a timestamp

SerialNumber
byte[] (read-only)

Default Value: ""

svtSignerNotFound3Failed to acquire the signing certificate. The signature cannot be validated.

svtFailure4General failure

SubjectKeyID
byte[] (read-only)

Default Value: ""

Contains the subject key identifier of the signing certificate.

Subject Key Identifier is a (non-critical) X.509 certificate extension which allows the identification of certificates containing a particular public key. In SecureBlackbox, the unique identifier is represented by a SHA-1 hash of the bit string of the subject public key.

SubjectRDN
string (read-only)

Default Value: ""

Contains the RDN of the owner of the signing certificate.

RDN is a number of OID=Value pairs declared in the certificate and providing the owner's details.

Default Value: False

Use this property to establish whether the signature contains an embedded timestamp.

ValidatedSigningTime
string (read-only)

Default Value: ""

Contains the certified signing time.

Use this property to obtain the signing time as certified by a timestamp from a trusted timestamping authority. This property is only non-empty if there was a valid timestamp included in the signature.

ClaimedSigningTime returns a non-trusted signing time from the signer's computer.

Both times are in UTC.

ValidationLog
string (read-only)

Default Value: ""

Contains the signing certificate's chain validation log. This information may be very useful in investigating chain validation failures.

Ciphersuites
string

Default Value: ""

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 that allow to blanketly enable or disable all ciphersuites at once.

Note: the list of ciphersuites provided to this property alters the baseline list of ciphersuites as defined by BaseConfiguration. 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:

ECCurves
string

Default Value: ""

Defines the elliptic curves to enable.

Extensions
string

Default Value: ""

Provides access to TLS extensions.

ForceResumeIfDestinationChanges
bool

Default Value: False

Whether to force TLS session resumption when the destination address changes.

PreSharedIdentity
string

Default Value: ""

Defines the identity used when the PSK (Pre-Shared Key) key-exchange mechanism is negotiated.

PreSharedKey
string

Default Value: ""

Contains the pre-shared for the PSK (Pre-Shared Key) key-exchange mechanism, encoded with base16.

PreSharedKeyCiphersuite
string

Default Value: ""

Defines the ciphersuite used for PSK (Pre-Shared Key) negotiation.

RenegotiationAttackPreventionMode
RenegotiationAttackPreventionModes

Default Value: 0

Selects renegotiation attack prevention mechanism.

The following options are available:

crapmCompatible0TLS 1.0 and 1.1 compatibility mode (renegotiation indication extension is disabled).
crapmStrict1Renegotiation attack prevention is enabled and enforced.
crapmAuto2Automatically choose whether to enable or disable renegotiation attack prevention.

RevocationCheck
RevocationCheckKinds

Default Value: 1

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.

crcNone0No revocation checking
crcAuto1Automatic mode selection. Currently this maps to crcAnyOCSPOrCRL, but it may change in the future.
crcAllCRL2Check all provided CRL endpoints for all chain certificates.
crcAllOCSP3Check all provided OCSP endpoints for all chain certificates.
crcAllCRLAndOCSP4Check all CRL and OCSP endpoints for all chain certificates.
crcAnyCRL5At least one CRL check for every certificate in the chain must succeed.
crcAnyOCSP6At least one OCSP check for every certificate in the chain must succeed.
crcAnyCRLOrOCSP7At least one CRL or OCSP check for every certificate in the chain must succeed. CRL endpoints are checked first.
crcAnyOCSPOrCRL8At 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.

Config Settings (CAdESVerifier 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.

CAdESVerifier Config Settings

AddReferencesToAllUsedCertsAndRevInfo:   whether to include all certificates and revocation references into the signature.

If this property is set, all certificates and revocation references collected during validation will be added to the signature. This feature is not required by the CAdES specification, however, some processors expect such behavior.

AddReferencesToIrrevocableCerts:   Whether references to irrevocable certificates should be included into the signature.

Set this property to True to include references to irrevocable certificates into the signature.

AddReferenceToSigningCert:   Whether a reference to the signing certificate should be included into the signature.

Set this property to True to include a reference to the signing certificate into the signature.

AllowPartialValidationInfo:   Whether to allow for missing validation info.

If this property is set to True, signature validation will not fail if validation information for a certificate is absent.

CmsOptAnnexKArchiveTimestampV2Mode:   Toggles use of Annex K method of calculating validation timestamp hashes.

This CMS message option toggles the use of Annex K method of calculating validation timestamp hashes. Switch this option off to stick to RFC5126 p6.3.5 method.

CmsOptCheckATSHashIndexElements:   Enables extra checks when processing ATSHashIndex attribute.

This CMS message option enables an extra check to make sure every hash in ATSHashIndex has an associated CMS element.

CmsOptCompareRDNAsStrings:   Enforces comparison of RDN elements as text strings, rather than their byte encodings.

This CMS message option enforces comparison of string RDN elements as text strings rather than their original byte encodings.

CmsOptDigitPADSSCompatibility:   Enables Digit PADSS compatibility mode.

This CMS message option enables compatibility mode with Digit PADSS software.

CmsOptForceSigningCertificateV2Usage:   Enforces use of signing-certificate-v2 attribute.

This CMS message option enforces the use of signing-certificate-v2 attribute in favour of older signing-certificate-v1. Current regulations require that signing-certificate-v2 is used at all times.

CmsOptIgnoreDERReqInArchiveTimestamps:   Switches off DER encoding requirement for archival timestamps.

This CMS message option switches off DER encoding requirement for archival timestamps (normally meaning no attribute reordering). This setting is a workaround for certain buggy CAdES products.

CmsOptImzagerMIMCompatibility:   Enables Imzager MIM compatibility mode.

This CMS message option enables compatibility mode with Imzager MIM software.

CmsOptIncludeCertToAttributes:   Regulates whether to include the signing certificate to the signature as the signing-certificate attribute.

This CMS message option controls inclusion of the signing certificate as the signing-certificate attribute. Current regulations require that this attribute is present.

CmsOptIncludeCertToMessage:   Regulates whether to include the signing certificate and its chain to the CMS.

This CMS message option controls inclusion of the signing certificate to the CMS structure. It is recommended that the certificate is included. Note that this option has no effect if the signature level used (e.g. XL) enforces inclusion of the certificate to the message.

CmsOptInsertContentType:   Regulates whether the content-type time attribute should be included in the signature structure.

This CMS message option specifies whether the content-type attribute should be included in the signature structure.

CmsOptInsertMessageDigests:   Regulates whether the message-digest signed attribute should be included in the signature structure.

This CMS message option controls inclusion of the message-digest attribute in the signature structure. Current regulations require that this attribute is present at all times.

CmsOptInsertSigningTime:   Regulates whether the signing-time attribute should be included in the signature structure.

This CMS message option specifies whether the signing-time attribute should be included in the signature structure. Switch it off to suppress inclusion of the signing-time attribute.

CmsOptSkipEnvContentInfoOnSigArchival:   Excludes hashing of enveloped content when calculating an archival timestamp.

This CMS message option excludes hashing of enveloped content when calculating an archival timestamp. This setting is a workaround for certain buggy CAdES products.

CmsOptUseATSHashIndexV1:   Enables use of ATSHashIndexV1 attribute.

This CMS message option enables use of deprecated ATSHashIndexV1 attribute when calculating archival timestamp V3 hashes.

CmsOptUseGeneralizedTimeFormat:   Enables or disables encoding of the signing-time attribute using ASN.1 GENERALIZEDTIME type.

This CMS message option controls whether the signing-time attribute should be encoded as GENERALIZEDTIME or UTCTIME. Current regulations require that the GENERALIZEDTIME type is used at all times.

CmsOptUseGenericSigAlgorithmOIDs:   Enables use of generic signature algorithm OIDs in the signature.

This CMS message option enforces the use of generic public key algorithm OIDs (e.g. rsaEncryption) instead of hash algorithm-specific variants (e.g. sha256withRsaEncryption). This setting is a workaround for certain buggy CAdES products.

CmsOptUsePlainContentForTimestampHashes:   Makes CAdESSigner ignore ASN.1 content formatting when calculating timestamp hashes.

This CMS message option causes CAdESSigner to ignore ASN.1 formatting when feeding content to timestamp hashes (might make a difference with split OCTETSTRINGs for extra long contents). This option is only applicable to content timestamps and ArchivalTimestampV1's. This setting is a workaround for certain buggy CAdES products.

DeepCountersignatureValidation:   Whether to validate countersignatures.

When this property is set, deep validation of countersignatures is performed.

DeepTimestampValidation:   Whether to perform deep validation of all timestamps.

When this property is set, deep validation of all signature's timestamps is performed.

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).

ForceCompleteChainValidation:   Whether to check the CA certificates when the signing certificate is invalid.

Set this property to True to check issuer (CA) certificates when the signing certificate is invalid.

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.

IgnoreChainValidationErrors:   Makes the component ignore chain validation issues.

Set this property to True to make the component ignore chain validation errors. Use with extra care.

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.

PolicyExplicitText:   The explicit text of the user notice.

This property specifies the explicit text of the user notice which is displayed when the signature is verified.

PolicyUNNumbers:   The noticeNumbers part of the NoticeReference CAdES attribute.

Defines the "noticeNumbers" part of the NoticeReference signature policy qualifier for CAdES-EPES.

PolicyUNOrganization:   The organization part of the NoticeReference qualifier.

Defines the "organization" part of the NoticeReference signature policy qualifier for CAdES-EPES.

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.

PSSUsed:   Whether RSASSA-PSS mode was used.

Although the RSASSA-PSS algorithm provides better security than a classic RSA scheme (PKCS#1-1.5), please take into account that RSASSA-PSS is a relatively new algorithm which may not be understood by older implementations.

ReportInvalidTimestamps:   Whether to rise errors on invalid timestamps.

When this property is set, each invalid timestamp will be reported by the Error event fired by the component.

SkipValidationTimestampedSignatures:   Whether to validate signatures with validation timestamps.

Set this property to False to enforce validation of the signatures containing validation timestamps.

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:

  • CA, revocation source, TLS key usage requirements are not mandated
  • Violation of OCSP issuer requirements are ignored
  • AuthorityKeyID extension in CRL and certificate issuing CAs are ignored (helps with incorrectly renewed certificates)
  • Basic constraints and name constraints of CA certificates are ignored
  • Some weaker algorithms are tolerated
UseArchivalTimestampV3:   Whether to apply archival timestamp V3.

Archival signature (CAdES-A) is built upon either a CAdES-X-L, or a CAdES-X-L with Time, by adding an archival timestamp. Set this property to True to use CAdES-X-L with Time Type 3.

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:

offNo caching (default)
localLocal caching
globalGlobal caching

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.

LogFlushMode:   Specifies the log flush mode.

Use this property to set the log flush mode. The following values are defined:

noneNo flush (caching only)
immediateImmediate flush (real-time logging)
maxcountFlush 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:

noneNone (by default)
fatalSevere errors that cause premature termination.
errorOther runtime errors or unexpected conditions.
warningUse of deprecated APIs, poor use of API, 'almost' errors, other runtime situations that are undesirable or unexpected, but not necessarily "wrong".
infoInteresting runtime events (startup/shutdown).
debugDetailed information on flow of through the system.
traceMore 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.

deleteolderDelete older entries from the cache upon reaching LogMaxEventCount
keepolderKeep 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.

StaticDNS:   Specifies whether static DNS rules should be used.

Set this property to enable or disable static DNS rules for the component. Works only if UseOwnDNSResolver is set to true.

Supported values are:

noneNo static DNS rules (default)
localLocal static DNS rules
globalGlobal 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 component) 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 devided 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 component is set to "local", the property returns/restores the rules from/to the internal storage of the component. If StaticDNS of the component 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 chached 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 components.

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).

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.
