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

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 the certificates to be added to this collection is roughly equivalent to that of the 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.

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

KnownCRLs Property (CAdESVerifier Component)

Additional CRLs for chain validation.

Syntax

public CRLList KnownCRLs { get; }

Syntax

public bool OfflineMode { get; set; }
Public Property OfflineMode As Boolean

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 the validation information included within the signature or provided via KnownCertificates, KnownCRLs, and other related properties.

OutputBytes Property (CAdESVerifier Component)

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

Syntax

public byte[] OutputBytes { get; }

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.

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 (CRLs) 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 the faster OCSP route and only demand one source to succeed) is a good choice for most typical validation environments. The "crcAll*" modes are much stricter, and may be used in scenarios where bulletproof validity information is essential.

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 as that of the 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.

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.

To verify enveloping signatures pass the signature via InputFile, InputStream or InputBytes properties.

To verify detached signatures pass the signature via InputFile, InputStream or InputBytes properties, and the data via DataStream or DataFile properties, and set Detached property.

Scope
int (read-only)

Default: 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: ""

The serial number of the signing certificate.

SignatureBytes
byte[] (read-only)

Default: ""

Returns the binary representation of the CAdES signature.

SignatureValidationResult
SignatureValidities (read-only)

Default: 0

The outcome of the cryptographic signature validation.

The following signature validity values are supported:

svtValid0The signature is valid

svtUnknown1Signature validity is unknown

svtCorrupted2The signature is corrupted

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

svtFailure4General failure

svtReferenceCorrupted5Reference corrupted (XML-based signatures only)

SubjectKeyID
byte[] (read-only)

Default: ""

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: ""

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.

Timestamped
bool (read-only)

Default: False

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

ValidatedSigningTime
string (read-only)

Default: ""

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: ""

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

Constructors

public CAdESSignature();
Public CAdESSignature()

Creates a new empty CAdES signature object.

Certificate Type

Encapsulates an individual X.509 certificate.

Remarks

This type keeps and provides access to X.509 certificate details.

Fields

Bytes
byte[] (read-only)

Default: ""

Returns the raw certificate data in DER format.

CA
bool

Default: False

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

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

CAKeyID
byte[] (read-only)

Default: ""

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

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

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

CertType
CertTypes (read-only)

Default: 0

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

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

Use the CertificateManager component to load or create new certificate and certificate requests objects.

CRLDistributionPoints
string

Default: ""

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

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

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

Curve
string

Default: ""

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

Fingerprint
string (read-only)

Default: ""

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

While there is no formal standard defining what a fingerprint is, a SHA1 hash of the certificate's DER-encoded body is typically used.

FriendlyName
string (read-only)

Default: ""

Contains an associated alias (friendly name) of the certificate. The friendly name is not a property of a certificate: it is maintained by the certificate media rather than being included in its DER representation. Windows certificate stores are one example of media that does support friendly names.

HashAlgorithm
string

Default: ""

Provides means to set the hash algorithm to be used in the subsequent operation on the certificate (such as generation or key signing). It is not a property of a certificate; use SigAlgorithm to find out the hash algorithm that is part of the certificate signature.

Use the KeyBits, Curve, and PublicKeyBytes fields to get more details about the key the certificate contains.

KeyBits
int (read-only)

Default: 0

Returns the length of the public key in bits.

This value indicates the length of the principal cryptographic parameter of the key, such as the length of the RSA modulus or ECDSA field. The key data returned by the PublicKeyBytes or PrivateKeyBytes field would typically contain auxiliary values, and therefore be longer.

KeyFingerprint
string (read-only)

Default: ""

Returns a SHA1 fingerprint of the public key contained in the certificate.

Note that the key fingerprint is different from the certificate fingerprint accessible via the Fingerprint field. The key fingeprint uniquely identifies the public key, and so can be the same for multiple certificates containing the same key.

KeyUsage
int

Default: 0

Indicates the purposes of the key contained in the certificate, in the form of an OR'ed flag set.

This value is a bit mask of the following values:

ckuUnknown0x00000Unknown key usage

ckuDigitalSignature0x00001Digital signature

ckuNonRepudiation0x00002Non-repudiation

ckuKeyEncipherment0x00004Key encipherment

ckuDataEncipherment0x00008Data encipherment

ckuKeyAgreement0x00010Key agreement

ckuKeyCertSign0x00020Certificate signing

ckuCRLSign0x00040Revocation signing

ckuEncipherOnly0x00080Encipher only

ckuDecipherOnly0x00100Decipher only

ckuServerAuthentication0x00200Server authentication

ckuClientAuthentication0x00400Client authentication

ckuCodeSigning0x00800Code signing

ckuEmailProtection0x01000Email protection

ckuTimeStamping0x02000Timestamping

ckuOCSPSigning0x04000OCSP signing

ckuSmartCardLogon0x08000Smartcard logon

ckuKeyPurposeClientAuth0x10000Kerberos - client authentication

ckuKeyPurposeKDC0x20000Kerberos - KDC

Set this field before generating the certificate to propagate the key usage flags to the new certificate.

KeyValid
bool (read-only)

Default: False

Returns True if the certificate's key is cryptographically valid, and False otherwise.

OCSPLocations
string

Default: ""

Locations of OCSP services that can be used to check this certificate's validity in real time, as recorded by the CA.

Set this field before calling the certificate manager's Generate method to propagate it to the new certificate.

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

OCSPNoCheck
bool

Default: False

Accessor to the value of the certificate's ocsp-no-check extension.

Origin
int (read-only)

Default: 0

Returns the location that the certificate was taken or loaded from.

PolicyIDs
string

Default: ""

Contains identifiers (OIDs) of the applicable certificate policies.

The Certificate Policies extension identifies a sequence of policies under which the certificate has been issued, and which regulate its usage.

Set this field when generating a certificate to propagate the policies information to the new certificate.

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

PrivateKeyBytes
byte[] (read-only)

Default: ""

Returns the certificate's private key in DER-encoded format. It is normal for this field to be empty if the private key is non-exportable, which, for example, is typical for certificates originating from hardware security devices.

PrivateKeyExists
bool (read-only)

Default: False

Indicates whether the certificate has a usable private key associated with it. If it is set to True, the certificate can be used for private key operations, such as signing or decryption.

This field is independent from PrivateKeyBytes, and can be set to True even if the former is empty. This would imply that the private key is non-exportable, but still can be used for cryptographic operations.

PrivateKeyExtractable
bool (read-only)

Default: False

Indicates whether the private key is extractable (exportable).

PublicKeyBytes
byte[] (read-only)

Default: ""

Contains the certificate's public key in DER format.

This typically would contain an ASN.1-encoded public key value. The exact format depends on the type of the public key contained in the certificate.

Qualified
bool (read-only)

Default: False

Indicates whether the certificate is qualified.

This property is set to True if the certificate is confirmed by a Trusted List to be qualified.

QualifiedStatements
QualifiedStatementsTypes

Default: 0

Returns a simplified qualified status of the certificate.

Qualifiers
string (read-only)

Default: ""

A list of qualifiers.

Contains a comma-separated list of qualifier aliases for the certificate, for example QCP-n-qscd,QCWithSSCD.

SelfSigned
bool (read-only)

Default: False

Indicates whether the certificate is self-signed (root) or signed by an external CA.

SerialNumber
byte[]

Default: ""

Returns the certificate's serial number.

The serial number is a binary string that uniquely identifies a certificate among others issued by the same CA. According to the X.509 standard, the (issuer, serial number) pair should be globally unique to facilitate chain building.

SigAlgorithm
string (read-only)

Default: ""

Indicates the algorithm that was used by the CA to sign this certificate.

A signature algorithm typically combines hash and public key algorithms together, such as sha256WithRSAEncryption or ecdsa-with-SHA256.

Source
PKISources (read-only)

Default: 0

Returns the source (location or disposition) of a cryptographic primitive entity, such as a certificate, CRL, or OCSP response.

Subject
string (read-only)

Default: ""

The common name of the certificate holder, typically an individual's name, a URL, an e-mail address, or a company name. This is part of a larger set of credentials available via SubjectRDN.

SubjectAlternativeName
string

Default: ""

Returns or sets the value of the Subject Alternative Name extension of the certificate.

Subject alternative names are used to provide additional names that are impractical to store in the main SubjectRDN field. For example, it is often used to store all the domain names that a TLS certificate is authorized to protect.

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

SubjectKeyID
byte[]

Default: ""

Contains a unique identifier of the certificate's cryptographic key.

Subject Key Identifier is a certificate extension which allows a specific public key to be associated with a certificate holder. Typically, subject key identifiers of CA certificates are recorded as respective CA key identifiers in the subordinate certificates that they issue, which facilitates chain building.

The SubjectKeyID and CAKeyID fields of self-signed certificates typically contain identical values, as in that specific case, the issuer and the subject are the same entity.

SubjectRDN
string

Default: ""

A list of Property=Value pairs that uniquely identify the certificate holder (subject).

Depending on the purpose of the certificate and the policies of the CA that issued it, the values included in the subject record may differ drastically and contain business or personal names, web URLs, email addresses, and other data.

Example: /C=US/O=Oranges and Apples, Inc./OU=Accounts Receivable/1.2.3.4.5=Value with unknown OID/CN=Margaret Watkins.

Valid
bool (read-only)

Default: False

Indicates whether or not the signature over the certificate or the request is valid and matches the public key contained in the CA certificate/request.

ValidFrom
string

Default: ""

The time point at which the certificate becomes valid, in UTC.

ValidTo
string

Default: ""

The time point at which the certificate expires, in UTC.

ccatRequireCert2

ECCurves
string

Default: ""

Defines the elliptic curves to enable.

Extensions
string

Default: ""

Provides access to TLS extensions.

ForceResumeIfDestinationChanges
bool

Default: False

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

PreSharedIdentity
string

Default: ""

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

PreSharedKey
string

Default: ""

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

PreSharedKeyCiphersuite
string

Default: ""

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

RenegotiationAttackPreventionMode
RenegotiationAttackPreventionModes

Default: 2

Selects the 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: 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 the faster OCSP route and only demand one source to succeed) is a good choice for most typical validation environments. The "crcAll*" modes are much stricter, and may be used in scenarios where bulletproof validity information is essential.

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 the 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 the 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 emulating 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 the '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
  • The 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 the automatic use of the 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 the chain validation module to 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 a 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)

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.

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:

noneNo rotation
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.
