""

Remarks

The ID of the pre-shared key used for DC request authentication.

Asynchronous DCAuth-driven communication requires that parties authenticate each other with a secret pre-shared cryptographic key. This provides an extra protection layer for the protocol and diminishes the risk of the private key becoming abused by foreign parties. Use this property to provide the pre-shared key identifier, and use ExternalCryptoKeySecret to pass the key itself.

The same KeyID/KeySecret pair should be used on the DCAuth side for the signing requests to be accepted.

Note: The KeyID/KeySecret scheme is very similar to the AuthKey scheme used in various Cloud service providers to authenticate users.

Example: signer.ExternalCrypto.KeyID = "MainSigningKey"; signer.ExternalCrypto.KeySecret = "abcdef0123456789";

Data Type

String

ExternalCryptoKeySecret Property (MessageSigner Component)

The pre-shared key used for DC request authentication.

Syntax

__property String ExternalCryptoKeySecret = { read=FExternalCryptoKeySecret, write=FSetExternalCryptoKeySecret };

TimestampServer Property (MessageSigner Component)

Default Value

""

Remarks

Use this property to provide the address of the Time Stamping Authority (TSA) server to be used for timestamping the signature.

SecureBlackbox supports RFC3161-compliant timestamping servers, available via HTTP or HTTPS.

If your timestamping service enforces credential-based user authentication (basic or digest), you can provide the credentials in the same URL:

http://user:password@timestamp.server.com/TsaService

For TSAs using certificate-based TLS authentication, provide the client certificate via the TLSClientChain property.

If this property is left empty, no timestamp will be added to the signature.

Starting from summer 2021 update (Vol. 2), the virtual timestamping service is supported, which allows you to intervene in the timestamping routine and provide your own handling for the TSA exchange. This may be handy if the service that you are requesting timestamps from uses a non-standard TSP protocol or requires special authentication option.

To employ the virtual service, assign an URI of the following format to this property:

virtual://localhost?hashonly=true&includecerts=true&reqpolicy=1.2.3.4.5&halg=SHA256

Subscribe to Notification event to get notified about the virtualized timestamping event. The EventID of the timestamping event is TimestampRequest. Inside the event handler, read the base16-encoded request from the EventParam parameter and forward it to the timestamping authority. Upon receiving the response, pass it back to the component, encoded in base16, via the TimestampResponse config property:

component.Config("TimestampResponse=308208ab...");

Note that all the exchange with your custom TSA should take place within the same invocation of the Notification event.

The hashonly parameter of the virtual URI tells the component to only return the timestamp message imprint via the EventParam parameter. If set to false, EventParam will contain the complete RFC3161 timestamping request.

The includecerts parameter specifies that the requestCertificates parameter of the timestamping request should be set to true.

The reqpolicy parameter lets you specify the request policy, and the halg parameter specifies the hash algorithm to use for timestamping.

All the parameters are optional.

  crcNone=0,
  crcAuto=1,

  crcAnyOCSP=6,
  crcAnyCRLOrOCSP=7,
  crcAnyOCSPOrCRL=8
};

Default Value

crcAuto

Remarks

Specifies the kind(s) of revocation check to perform.

Revocation checking is necessary to ensure the integrity of the chain and obtain up-to-date certificate validity and trustworthiness information.

This setting controls the way the revocation checks are performed 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.

This property is not available at design time.

Config Method (MessageSigner Component)

Sets or retrieves a configuration setting.

Syntax

String __fastcall Config(String ConfigurationString);

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.

Countersign Method (MessageSigner Component)

Countersigns an existing signature.

Syntax

void __fastcall Countersign();

Remarks

Use this method to certify an existing document signature. Countersigning doesn't alter the existing signatures or the signed document itself.

DoAction Method (MessageSigner Component)

Performs an additional action.

Syntax

String __fastcall DoAction(String ActionID, String ActionParams);

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 insensitive) 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;....

ExtractAsyncData Method (MessageSigner Component)

Extracts user data from the DC signing service response.

Syntax

String __fastcall ExtractAsyncData(String AsyncReply);

Remarks

Call this method before finalizing the asynchronous signing process to extract the data passed to the ExternalCrypto.Data property on the pre-signing stage.

The Data parameter can be used to pass some state or document identifier along with the signing request from the pre-signing to the completion async stage.

Sign Method (MessageSigner Component)

Signs the data.

Syntax

void __fastcall Sign();

Remarks

This method signs the data provided via InputFile (or InputStream) with SigningCertificate, and saves the signature in OutputFile (OutputStream). Set the desired signature variant via SignatureType property.

The component automatically timestamps the created signature if a TimestampServer is provided.

SignAsyncBegin Method (MessageSigner Component)

Initiates the asynchronous signing operation.

Syntax

String __fastcall SignAsyncBegin();

Remarks

When using the DC framework, call this method to initiate the asynchronous signing process. Upon completion, a pre-signed copy of the document will be saved in OutputFile (or OutputStream). Keep the pre-signed copy somewhere local, and pass the returned string ('the request state') to the DC processor for handling.

Upon receiving the response state from the DC processor, assign the path to the pre-signed copy to InputFile (or InputStream), and call SignAsyncEnd to finalize the signing.

Note that depending on the signing method and DC configuration used, you may still need to provide the public part of the signing certificate via the SigningCertificate property.

Use the ExternalCrypto.AsyncDocumentID property to supply a unique document ID to include in the request. This is helpful when creating batches of multiple async requests, as it allows you to pass the whole response batch to SignAsyncEnd and expect it to recover the correct response from the batch automatically.

AsyncState is a message of the distributed cryptography (DC) protocol. The DC protocol is based on the exchange of async states between a DC client (an application that wants to sign a PDF, XML, or Office document) and a DC server (an application that controls access to the private key). An async state can carry one or more signing requests, comprised of document hashes, or one or more signatures produced over those hashes.

In a typical scenario you get a client-side async state from the SignAsyncBegin method. This state contains document hashes to be signed on the DC server side. You then send the async state to the DC server (often represented by the DCAuth component), which processes it and produces a matching signature state. The async state produced by the server is then passed to the SignAsyncEnd method.

SignAsyncEnd Method (MessageSigner Component)

Completes the asynchronous signing operation.

Syntax

void __fastcall SignAsyncEnd(String AsyncReply);

Remarks

When using the DC framework, call this method upon receiving the response state from the DC processor to complete the asynchronous signing process.

Before calling this method, assign the path to the pre-signed copy of the document obtained from the prior SignAsyncBegin call to InputFile (or InputStream). The method will embed the signature into the pre-signed document, and save the complete signed document to OutputFile (or OutputStream).

Note that depending on the signing method and DC configuration used, you may still need to provide the public part of the signing certificate via the SigningCertificate property.

Use the ExternalCrypto.AsyncDocumentID parameter to pass a specific document ID if using batched AsyncReply. If used, it should match the value provided on the pre-signing (SignAsyncBegin) stage.

AsyncState is a message of the distributed cryptography (DC) protocol. The DC protocol is based on the exchange of async states between a DC client (an application that wants to sign a PDF, XML, or Office document) and a DC server (an application that controls access to the private key). An async state can carry one or more signing requests, comprised of document hashes, or one or more signatures produced over those hashes.

In a typical scenario you get a client-side async state from the SignAsyncBegin method. This state contains document hashes to be signed on the DC server side. You then send the async state to the DC server (often represented by the DCAuth component), which processes it and produces a matching signature state. The async state produced by the server is then passed to the SignAsyncEnd method.

Timestamp Method (MessageSigner Component)

Timestamps a signature.

Syntax

void __fastcall Timestamp();

Remarks

This method timestamps an existing PKCS#7 signature with TimestampServer. Pass your existing signature via InputFile (or InputStream), and collect the timestamped variant from OutputFile (OutputStream).

Error Event (MessageSigner Component)

Information about errors during PKCS#7 message signing.

Syntax

typedef struct {
  int ErrorCode;
  String Description;
} TsbxMessageSignerErrorEventParams;
typedef void __fastcall (__closure *TsbxMessageSignerErrorEvent)(System::TObject* Sender, TsbxMessageSignerErrorEventParams *e);
__property TsbxMessageSignerErrorEvent OnError = { read=FOnError, write=FOnError };

Remarks

The event is fired in case of exceptional conditions during message processing.

ErrorCode contains an error code and Description contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Messages section.

ExternalSign Event (MessageSigner Component)

Handles remote or external signing initiated by the SignExternal method or other source.

Syntax

typedef struct {
  String OperationId;
  String HashAlgorithm;
  String Pars;
  String Data;
  String SignedData;
} TsbxMessageSignerExternalSignEventParams;
typedef void __fastcall (__closure *TsbxMessageSignerExternalSignEvent)(System::TObject* Sender, TsbxMessageSignerExternalSignEventParams *e);
__property TsbxMessageSignerExternalSignEvent OnExternalSign = { read=FOnExternalSign, write=FOnExternalSign };

Remarks

Assign a handler to this event if you need to delegate a low-level signing operation to an external, remote, or custom signing engine. Depending on the settings, the handler will receive a hashed or unhashed value to be signed.

The event handler must pass the value of Data to the signer, obtain the signature, and pass it back to the component via the SignedData parameter.

OperationId provides a comment about the operation and its origin. It depends on the exact component being used, and may be empty. HashAlgorithm specifies the hash algorithm being used for the operation, and Pars contains algorithm-dependent parameters.

The component uses base16 (hex) encoding for the Data, SignedData, and Pars parameters. If your signing engine uses a different input and output encoding, you may need to decode and/or encode the data before and/or after the signing.

A sample MD5 hash encoded in base16: a0dee2a0382afbb09120ffa7ccd8a152 - lower case base16 A0DEE2A0382AFBB09120FFA7CCD8A152 - upper case base16

A sample event handler that uses the .NET RSACryptoServiceProvider class may look like the following: signer.OnExternalSign += (s, e) => { var cert = new X509Certificate2("cert.pfx", "", X509KeyStorageFlags.Exportable); var key = (RSACryptoServiceProvider)cert.PrivateKey; var dataToSign = e.Data.FromBase16String(); var signedData = key.SignHash(dataToSign, "2.16.840.1.101.3.4.2.1"); e.SignedData = signedData.ToBase16String(); };

Notification Event (MessageSigner Component)

This event notifies the application about an underlying control flow event.

Syntax

typedef struct {
  String EventID;
  String EventParam;
} TsbxMessageSignerNotificationEventParams;
typedef void __fastcall (__closure *TsbxMessageSignerNotificationEvent)(System::TObject* Sender, TsbxMessageSignerNotificationEventParams *e);
__property TsbxMessageSignerNotificationEvent OnNotification = { read=FOnNotification, write=FOnNotification };

Remarks

The component fires this event to let the application know about some event, occurrence, or milestone in the component. For example, it may fire to report completion of the document processing. The list of events being reported is not fixed, and may be flexibly extended over time.

The unique identifier of the event is provided in the EventID parameter. EventParam contains any parameters accompanying the occurrence. Depending on the type of the component, the exact action it is performing, or the document being processed, one or both may be omitted.

This component can fire this event with the following EventID values:

TimestampRequest Event (MessageSigner Component)

Fires when the component is ready to request a timestamp from an external TSA.

Syntax

typedef struct {
  String TSA;
  String TimestampRequest;
  String TimestampResponse;
  bool SuppressDefault;
} TsbxMessageSignerTimestampRequestEventParams;
typedef void __fastcall (__closure *TsbxMessageSignerTimestampRequestEvent)(System::TObject* Sender, TsbxMessageSignerTimestampRequestEventParams *e);
__property TsbxMessageSignerTimestampRequestEvent OnTimestampRequest = { read=FOnTimestampRequest, write=FOnTimestampRequest };

Remarks

Subscribe to this event to intercept timestamp requests. You can use it to override timestamping requests and perform them in your code.

The TSA parameter indicates the timestamping service being used. It matches the value passed to the TimestampServer property. Set the SuppressDefault parameter to false if you would like to stop the built-in TSA request from going ahead. The built-in TSA request is also not performed if the returned TimestampResponse parameter is not empty.

TLSCertNeeded Event (MessageSigner Component)

Fires when a remote TLS party requests a client certificate.

Syntax

typedef struct {
  String Host;
  String CANames;
} TsbxMessageSignerTLSCertNeededEventParams;
typedef void __fastcall (__closure *TsbxMessageSignerTLSCertNeededEvent)(System::TObject* Sender, TsbxMessageSignerTLSCertNeededEventParams *e);
__property TsbxMessageSignerTLSCertNeededEvent OnTLSCertNeeded = { 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 (MessageSigner Component)

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

Syntax

typedef struct {
  String ServerHost;
  String ServerIP;
  bool Accept;
} TsbxMessageSignerTLSCertValidateEventParams;
typedef void __fastcall (__closure *TsbxMessageSignerTLSCertValidateEvent)(System::TObject* Sender, TsbxMessageSignerTLSCertValidateEventParams *e);
__property TsbxMessageSignerTLSCertValidateEvent OnTLSCertValidate = { 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 (MessageSigner Component)

Fires when a TLS handshake with Host successfully completes.

Syntax

typedef struct {
  String Host;
  String Version;
  String Ciphersuite;
  DynamicArray ConnectionId;
  bool Abort;
} TsbxMessageSignerTLSEstablishedEventParams;
typedef void __fastcall (__closure *TsbxMessageSignerTLSEstablishedEvent)(System::TObject* Sender, TsbxMessageSignerTLSEstablishedEventParams *e);
__property TsbxMessageSignerTLSEstablishedEvent OnTLSEstablished = { 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 (MessageSigner Component)

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

Syntax

typedef struct {
  String Host;
  bool Abort;
} TsbxMessageSignerTLSHandshakeEventParams;
typedef void __fastcall (__closure *TsbxMessageSignerTLSHandshakeEvent)(System::TObject* Sender, TsbxMessageSignerTLSHandshakeEventParams *e);
__property TsbxMessageSignerTLSHandshakeEvent OnTLSHandshake = { 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 (MessageSigner Component)

Reports the graceful closure of a TLS connection.

Syntax

typedef struct {
  String Host;
} TsbxMessageSignerTLSShutdownEventParams;
typedef void __fastcall (__closure *TsbxMessageSignerTLSShutdownEvent)(System::TObject* Sender, TsbxMessageSignerTLSShutdownEventParams *e);
__property TsbxMessageSignerTLSShutdownEvent OnTLSShutdown = { 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.

Config Settings (MessageSigner 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.
