AllSignaturesValid Property (SOAPVerifier Component)

The cumulative validity of all signatures.

Syntax

property AllSignaturesValid: Boolean read get_AllSignaturesValid;

Default Value

false

Remarks

Use this property to check if all the signatures found in the message or document are valid.

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

AutoValidateSignatures Property (SOAPVerifier Component)

Specifies whether component should validate any present signatures when the document is opened.

Syntax

property AutoValidateSignatures: Boolean read get_AutoValidateSignatures write set_AutoValidateSignatures;

Default Value

true

Remarks

This setting is switched on by default. You can choose to set this property to false in order to validate the signatures manually on a later stage using the Revalidate method.

BlockedCertificates Property (SOAPVerifier Component)

The certificates that must be rejected as trust anchors.

Syntax

property BlockedCertificates: TsbxCertificateList read get_BlockedCertificates write set_BlockedCertificates;

Remarks

Use this property to provide a list of compromised or blocked certificates. Any chain containing a blocked certificate will fail validation.

This property is not available at design time.

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

Certificates Property (SOAPVerifier Component)

A collection of certificates included in the electronic signature.

Syntax

property Certificates: TsbxCertificateList read get_Certificates;

Remarks

Use this property to access all certificates included into the signature(s) by its creator.

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

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

CRLs Property (SOAPVerifier Component)

A collection of certificate revocation lists embedded into the signature by the signer.

Syntax

property CRLs: TsbxCRLList read get_CRLs;

Remarks

Use this property to access the CRLs embedded into the signature by the signer.

false

Remarks

This property is reserved for future use.

IgnoreChainValidationErrors Property (SOAPVerifier Component)

Makes the component tolerant to chain validation errors.

Syntax

property IgnoreChainValidationErrors: Boolean read get_IgnoreChainValidationErrors write set_IgnoreChainValidationErrors;

Default Value

false

Remarks

If this property is set to True, any errors emerging during certificate chain validation will be ignored. This setting may be handy if the purpose of validation is the creation of an LTV signature, and the validation is performed in an environment that doesn't trust the signer's certificate chain.

InputBytes Property (SOAPVerifier Component)

Use this property to pass the input to component in byte array form.

Syntax

property InputBytes: TBytes read get_InputBytes write set_InputBytes;

Remarks

Assign a byte array containing the data to be processed to this property.

This property is not available at design time.

InputFile Property (SOAPVerifier Component)

A path to the signed SOAP message.

Syntax

property InputFile: String read get_InputFile write set_InputFile;

Default Value

''

Remarks

Provide a path to the SOAP message to be verified.

KnownCertificates Property (SOAPVerifier 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 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 (SOAPVerifier Component)

Additional CRLs for chain validation.

Syntax

property KnownCRLs: TsbxCRLList read get_KnownCRLs write set_KnownCRLs;

Remarks

Use this property to supply additional CRLs that might be needed for chain validation. This property may be helpful when a chain is validated in offline mode, and the associated CRLs are stored separately from the signed message or document.

This property is not available at design time.

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

KnownOCSPs Property (SOAPVerifier Component)

Additional OCSP responses for chain validation.

Syntax

property KnownOCSPs: TsbxOCSPResponseList read get_KnownOCSPs write set_KnownOCSPs;

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

OutputBytes Property (SOAPVerifier Component)

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

Syntax

property OutputBytes: TBytes read get_OutputBytes;

Remarks

Read the contents of this property after the operation has completed to read the produced output. This property will only be set if the OutputFile and OutputStream properties had not been assigned.

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

OutputFile Property (SOAPVerifier Component)

A file where the extracted SOAP message is to be saved.

Syntax

property OutputFile: String read get_OutputFile write set_OutputFile;

Profile Property (SOAPVerifier 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 (SOAPVerifier 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 and not available at design time.

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

RevocationCheck Property (SOAPVerifier Component)

Specifies the kind(s) of revocation check to perform for all chain certificates.

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 (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.

This setting controls the way the revocation checks are performed for every certificate in the chain. 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.

Note: If no CRL or OCSP endpoints are provided by the CA, the revocation check will be considered successful. This is because the CA chose not to supply revocation information for its certificates, meaning they are considered irrevocable.

Note: Within each of the above settings, if any retrieved CRL or OCSP response indicates that the certificate has been revoked, the revocation check fails.

Signatures Property (SOAPVerifier Component)

All signatures found in the SOAP message.

Syntax

property Signatures: TsbxSOAPSignatureList read get_Signatures;

Remarks

This property contains a list of all signatures made over the SOAP message.

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

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

SocketSettings Property (SOAPVerifier Component)

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

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

TLSClientChain Property (SOAPVerifier Component)

The TLS client certificate chain.

Syntax

property TLSClientChain: TsbxCertificateList read get_TLSClientChain write set_TLSClientChain;

Remarks

Assign a certificate chain to this property to enable TLS client authentication in the component. Note that the client's end-entity certificate should have a private key associated with it.

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

TLSSettings Property (SOAPVerifier Component)

Manages TLS layer settings.

Syntax

property TLSSettings: TsbxTLSSettings read get_TLSSettings;

Remarks

Use this property to tune up the TLS layer parameters.

This property is read-only.

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

TrustedCertificates Property (SOAPVerifier Component)

A list of trusted certificates for chain validation.

Syntax

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 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.

This property is not available at design time.

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

ValidationMoment Property (SOAPVerifier Component)

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 the signature creation time or the 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.

XPathNamespaces Property (SOAPVerifier Component)

Specifies namespaces for an XPath expression.

Syntax

property XPathNamespaces: TsbxXMLNamespaceList read get_XPathNamespaces write set_XPathNamespaces;

Remarks

Config Method (SOAPVerifier 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 (SOAPVerifier Component)

  var ValidateSignature: Boolean;
  var ValidateChain: Boolean
) of Object;

property OnSignatureFound: TSignatureFoundEvent read FOnSignatureFound write FOnSignatureFound;

Remarks

This event tells the application that signature validation is about to start, and provides the details about the signer's certificate via its IssuerRDN, SerialNumber, and SubjectKeyID parameters. It fires for every signature located in the verified document or message.

The CertFound parameter is set to True if the component has found the needed certificate in one of the known locations, and to False otherwise, in which case you must provide it manually via the KnownCertificates property.

Signature validation consists of two independent stages: cryptographic signature validation and chain validation. Separate validation results are reported for each, with the SignatureValidationResult and ChainValidationResult properties respectively.

Use the ValidateSignature and ValidateChain parameters to tell the verifier which stages to include in the validation.

SignatureValidated Event (SOAPVerifier Component)

The CertFound parameter is set to True if the component has found the needed certificate in one of the known locations, and to False otherwise, in which case you must provide it manually via the KnownCertificates property.

Just like with signature validation, timestamp validation consists of two independent stages: cryptographic signature validation and chain validation. Separate validation results are reported for each, with the ValidationResult and ChainValidationResult properties respectively.

Use the ValidateSignature and ValidateChain parameters to tell the verifier which stages to include in the validation.

TimestampValidated Event (SOAPVerifier Component)

Reports the completion of the timestamp validation routine.

Syntax

  const CANames: String
) of Object;

property OnTLSCertNeeded: TTLSCertNeededEvent read FOnTLSCertNeeded write FOnTLSCertNeeded;

Remarks

This event fires to notify the implementation that a remote TLS server has requested a client certificate. The Host parameter identifies the host that makes a request, and the CANames parameter (optional, according to the TLS spec) advises on the accepted issuing CAs.

Use the TLSClientChain property in response to this event to provide the requested certificate. Please make sure the client certificate includes the associated private key. Note that you may set the certificates before the connection without waiting for this event to fire.

This event is preceded by the TLSHandshake event for the given host and, if the certificate was accepted, succeeded by the TLSEstablished event.

TLSCertValidate Event (SOAPVerifier Component)

This event is fired upon receipt of the TLS server's certificate, allowing the user to control its acceptance.

Syntax

type TTLSCertValidateEvent = procedure (
  Sender: TObject;
  const ServerHost: String;
  const ServerIP: String;
  var Accept: Boolean
) of Object;

property OnTLSCertValidate: TTLSCertValidateEvent read FOnTLSCertValidate write FOnTLSCertValidate;

Remarks

This event is fired during a TLS handshake. Use the TLSServerChain property to access the certificate chain. In general, components may contact a number of TLS endpoints during their work, depending on their configuration.

Accept is assigned in accordance with the outcome of the internal validation check performed by the component, and can be adjusted if needed.

TLSEstablished Event (SOAPVerifier Component)

Fires when a TLS handshake with Host successfully completes.

Syntax

type TTLSEstablishedEvent = procedure (
  Sender: TObject;
  const Host: String;

  ConnectionId: TBytes;
  var Abort: Boolean
) of Object;

property OnTLSEstablished: TTLSEstablishedEvent read FOnTLSEstablished write FOnTLSEstablished;

Remarks

The component uses this event to notify the application about a successful completion of a TLS handshake.

The Version, Ciphersuite, and ConnectionId parameters indicate the security parameters of the new connection. Use the Abort parameter if you need to terminate the connection at this stage.

TLSHandshake Event (SOAPVerifier Component)

Fires when a new TLS handshake is initiated, before the handshake commences.

Syntax

type TTLSHandshakeEvent = procedure (
  Sender: TObject;
  const Host: String;
  var Abort: Boolean
) of Object;

property OnTLSHandshake: TTLSHandshakeEvent read FOnTLSHandshake write FOnTLSHandshake;

Remarks

The component uses this event to notify the application about the start of a new TLS handshake to Host. If the handshake is successful, this event will be followed by the TLSEstablished event. If the server chooses to request a client certificate, the TLSCertNeeded event will also be fired.

TLSShutdown Event (SOAPVerifier Component)

Reports the graceful closure of a TLS connection.

Syntax

type TTLSShutdownEvent = procedure (
  Sender: TObject;
  const Host: String
) of Object;

property OnTLSShutdown: TTLSShutdownEvent read FOnTLSShutdown write FOnTLSShutdown;

Remarks

This event notifies the application about the closure of an earlier established TLS connection. Note that only graceful connection closures are reported.

Certificate Type

Provides details of an individual X.509 certificate.

Remarks

This type provides access to X.509 certificate details.

Fields

Constructors

>

constructor Create();

Creates a new object with default field values.

CRL Type

Represents a Certificate Revocation List.

Remarks

CRLs store information about revoked certificates, i.e., certificates that have been identified as invalid by their issuing certificate authority (CA) for any number of reasons.

Each CRL object lists certificates from a single CA and identifies them by their serial numbers. A CA may or may not publish a CRL, may publish several CRLs, or may publish the same CRL in multiple locations.

Unlike OCSP responses, CRLs only list certificates that have been revoked. They do not list certificates that are still valid.

Fields

Constructors

>

constructor Create();

Creates an empty CRL object.

OCSPResponse Type

Represents a single OCSP response originating from an OCSP responder.

Remarks

OCSP is a protocol that allows verification of certificate status in real-time, and is an alternative to Certificate Revocation Lists (CRLs).

An OCSP response is a snapshot of the certificate status at a given time.

Fields

Constructors

>

constructor Create();

Creates an empty OCSP response object.

TimestampInfo Type

A container for timestamp information.

Remarks

The TimestampInfo object contains details of a third-party timestamp and the outcome of its validation.

Fields

Constructors

>

constructor Create();

Creates a new TimestampInfo object with default field values.

TLSSettings Type

A container for TLS connection settings.

Remarks

Creates a new TLSSettings object.

XMLNamespace Type

Represents an XML namespace map for XPath expressions.

Remarks

This class defines the correspondence between Prefixes and namespace URIs.

Fields

Constructors

>

constructor Create();

Creates a new XML namespace object.

XMLReference Type

Represents an XML reference element.

Remarks

XMLReference specifies the digest algorithm and digest value, and, optionally: an identifier of the object being signed, the type of the object, and/or a list of transforms to be applied prior to digesting.

Fields

Constructors

>

constructor Create();

Creates a new XML reference element.

>

constructor Create(valID: String);

Creates a new XML reference element from its ID .

>

constructor Create(valID: String; valURI: String);

Creates a new XML reference element from its ID and URI reference to the external data.

Config Settings (SOAPVerifier 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.
