The CAdESSigner component creates CAdES- and CMS-compliant electronic signatures.

Syntax

TsbxCAdESSigner

Remarks

CAdESSigner can sign documents and files in compliance with CMS Advanced Electronic Signatures (CAdES) specification. Originally developed by ETSI on the basis of PKCS#7 format and initially adopted in the European Union, CAdES has quickly become a recognized international standard for signing all sorts of electronic documents.

Besides being a signature standard in its own right, CAdES is used as part of other higher-level signature standards, such as PAdES or S/MIME. It provides a convenient framework for creating short-lived and long-term signatures over any kind of documents, and is now used by governments, healthcare providers, banks, and independent service providers all across the globe.

Standards and technologies supported

CAdESSigner offers the following signing capabilities:

• Create and upgrade CAdES signatures in accordance with the most recent CAdES specification (ETSI EN 319 122). Some features from older versions are also supported.
• All profiles are supported (BES, EPES, T, C, X, XL, A, including Baseline and Extended variants).
• Timestamping using external TSAs.
• All industry-standard cryptographic algorithms (RSA, ECDSA, SHA256-512, and many others).

Configuring the signature parameters

Configuring CAdESSigner to make it produce a signature of the right type is the main task you would need to perform in your code. Normally the service or software you will be communicating your signed documents to will provide you with the list of requirements that your signatures should match.

Typically, those will dictate the following key aspects of the signatures:

• The signature Level (such BES, T, XL, A, or XLong). This can be passed as the Level parameter of the Sign method.
• Whether the signature should be detached or enveloping: this can be adjusted via the Detached parameter of the Sign method.
• When creating a timestamped signature (such as T or A), provide the address of your online TSA service via TimestampServer property.
• When creating long-term signatures that include the signing chain and validation material, tune up validation parameters via RevocationCheck, OfflineMode, and IgnoreChainValidationErrors properties.

In some circumstances you will also need to adjust the following lower-level settings:

• Set ClaimedSigningTime to include the local signature creation time (not timestamped by a TTP).
• Specify EPES signature parameters via PolicyHash, PolicyHashAlgorithm, PolicyID, and PolicyURI properties.
• Provide the hash algorithm via the HashAlgorithm property.

Signing certificates

CAdESSigner can use certificates residing on different media. Besides generic certificates stored in PFX or PEM files (A1), it can operate with non-exportable certificates residing on hardware media (A3) or in the cloud.

Non-exportable certificates can be accessed transparently via a Windows CSP or a PKCS#11 driver, if supplied by the certificate issuer. Proprietary interfaces can be plugged in with the external signing feature (see below).

You can use CertificateManager and CertificateStorage components to access the signing certificate. Assign the certificate to SigningCertificate property, and optionally provide the remainder of its chain via SigningChain property.

Note: If signing with a non-exportable key (such as residing on a hardware device or in the cloud), please make sure you keep the original CertificateStorage object open until the signing is completed. This is because the storage component provides a 'bridge' to the private key. If the storage is closed prematurely, this bridge is destroyed, and the private key can't be used.

You don't need to provide a signing certificate or chain when timestamping and upgrading signatures, since this type of operation does not involve the signing private key.

Signing a file

Now that you have set up all signature properties and attached the signing certificate, it is time to proceed to signing. You can provide the input document in one of the following forms: as a file (assign the path to InputFile property), as a stream (assign to InputStream property), or as a byte array (assign to InputBytes). Similarly, the output can be collected in one of the same forms, either by passing the destination path or stream via OutputFile and OutputStream respectively, or by reading the resulting document bytes from the OutputBytes property after the signing completes.

Having set up the input and output (unless using OutputBytes, which should be read later), call the component's Sign method, passing the desired signature level and type as parameters. This will initiate the signing process. Depending on the settings, the signing may be as straightforward as calculating the document hash and signing it with the private key (e.g. in CAdES-BES or B-B variant), or it may involve advanced chain validation routines (CAdES-XL or -A). During the latter the component may contact a number of external revocation information sources (CRL and OCSP servers) to establish the validity of the signing certificate.

If a TSA server was provided via the TimestampServer property, the component will contact it too to timestamp the new signature.

During the signing CAdESSigner may fire events to let your code know of certain conditions. It may fire TLSCertValidate if one of the HTTP endpoints involved in the operation (which may be a CRL, OCSP, or TSA service) works over TLS and needs its certificate to be validated.

Apart from signing, CAdESSigner can perform operations on signatures of other kinds. Use Upgrade method to upgrade an existing CAdES signature to a higher level (e.g. BES to XL). Use Timestamp to add a generic or validation timestamp to an existing signature. Use the Countersign method to add a countersignature to an existing signature. For any of these operations the input should constitute a valid CAdES signature.

External signing and DCAuth

CAdESSigner, like many other components offered by the product, supports two methods of signing with external keys. These methods are fully independent of each other: you can choose the one that suits your usage scenario best.

Synchronous method: ExternalSign

This is a simpler method that basically lets you infiltrate into the heart of the signing routine by taking care of the hash signing operation. The component does the rest of the job (hash calculation, preparation of signature objects, CRL/OCSP retrieval).

To initiate this method, call SignExternal instead of Sign. When the hash is ready, it will be passed back to your code with ExternalSign event. Your event handler needs to sign the hash with the private key and return the created signature back to the component - which will embed it into the document.

You don't need your signing certificate to contain an associated private key when using this method. The certificate itself (its public copy) may be needed though, as it is often included in the hash calculation.

This method is synchronous, meaning SignExternal provides you the results immediately upon its completion.

Asynchronous method: DCAuth

DCAuth is a SecureBlackbox-own know-how technology. This protocol was designed to allow sharing of private keys across environments, allowing the signer and the private key to reside on different systems. It works in the following way:

• The signing party - such as CAdESSigner - initiates the operation using SignAsyncBegin call. This produces two outcomes: a pre-signed document (a document with a blank signature placeholder), and a request state (an object containing a hash that needs to be signed). At this point the CAdESSigner instance can be released, and the process itself terminated (which may be useful when run as part of a web page).
• The request state is passed to the private key holder party. The private key holder passes the request state to a DCAuth object, which parses the request state, extracts the hash, and signs it. The output of DCAuth processing is another object, response state, which contains the signature. The private key holder then sends the response state back to the signing party.
• The signing party re-creates the controls, and passes the response state, together with the pre-signed version of the document, to the signer's SignAsyncEnd method. SignAsyncEnd extracts the signature from the response state and incorporates it into the pre-signed document.

This method is asynchronous in that sense that, from the signing party's viewpoint, it splits the signing operation into the pre-signing and completion stages which can be performed independently from each other and in different execution contexts. This makes this method particularly helpful for use in web pages and other scenarios where the signing key is not available in real time.

Fine-grained chain validation setup

Chain validation is a sophisticated, multi-faceted procedure that involves a lot of variables. Depending on the configuration of your operating environment, the specifics of the PKI framework being used, and the validation policy you need to follow, you may want to tune up your chain validation parameters so they fit them best. A summary of such parameters is given below.

• RevocationCheck lets you choose between and/or prioritize revocation origins. OCSP sources are often preferred to CRL because of their real-time capability and the smaller size of validation tokens they produce.
• OfflineMode is a master switch that stops the component from looking for any validation tokens online. If this property is switched on, the component will only use the KnownCertificates, TrustedCertificates, KnownCRLs, and KnownOCSPs collections to look for the missing validation material.
• IgnoreChainValidationErrors makes the component ignore any major validation issues it encounters (such us an untrusted chain or missing CRL). This option is handy for debugging and for creating signatures in the environments where the signing certificate is not trusted.
• KnownCertificates, KnownCRLs, and KnownOCSPs let you provide your own validation material. This may be useful when working in OfflineMode, where the signer has no access to the validation sources, or where the validation material has already been collected.
• TrustedCertificates lets you provide a list of trust anchors, either as a complement to the system's or as an alternative to it.
• BlockedCertificates lets you provide a list of blocked/distrusted certificates. Any CA certificate contained in it will be deemed untrusted/invalid.

The following parameters are not directly related to chain validation, but may have an implicit effect on it.

• Proxy, SocketSettings, and TLSSettings let you tune up the connectivity and TLS options in accordance with local preferences.
• TLSClientChain lets you provide the client certificate and its chain for TLS client authentication.
• Subscribe to TLSCertValidate to validate any TLS certificates of the services involved in chain validation.

The results of the chain validation procedure, upon its completion, are published in the following properties:

• ChainValidationResult contains the primary result of the chain validation routine: valid, valid but untrusted, invalid, or undefined.
• ChainValidationDetails provides the details of the factors that contributed to the chain validation result, such as an outdated certificate, a missing CRL, or a missing CA certificate.
• ValidationLog contains the detailed chain validation log. The log can often be very helpful in nailing down various validation issues.

String

ExternalCryptoKeyID Property (CAdESSigner Component)

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

Syntax

__property String ExternalCryptoKeyID = { read=FExternalCryptoKeyID, write=FSetExternalCryptoKeyID };

Default Value

""

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 (CAdESSigner Component)

The pre-shared key used for DC request authentication.

Syntax

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

};

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.

TimestampServer Property (CAdESSigner Component)

The address of the timestamping server.

Syntax

__property String TimestampServer = { read=FTimestampServer, write=FSetTimestampServer };

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.

  crcAnyCRL=5,
  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.

Archive Method (CAdESSigner Component)

Archives the signature.

Syntax

void __fastcall Archive(bool Baseline);

Set Baseline to True to produce a baseline CAdES-A.

Config Method (CAdESSigner 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 (CAdESSigner Component)

Countersigns the existing signature.

Syntax

void __fastcall Countersign(int Level, bool SerialSignature);

Remarks

Use this method to countersign a signature. Use the Level parameter to provide the desired CAdES level (see below).

SerialSignature specifies whether the new countersignature should be added on the same level of hierarchy as the original signature (signature-over-data, True), or as a true countersignature (signature-over-signature, False).

CAdES defines a number of different 'levels' of signatures. Supported signature levels:

CountersignAsyncBegin Method (CAdESSigner Component)

Initiates asynchronous (DC) countersigning.

Syntax

String __fastcall CountersignAsyncBegin(int Level, bool SerialSignature);

Remarks

Call this method to initiate an asynchronous signing process. Pass the obtained async state to the DC processor for signing. To finalize the signing, pass the async state received from the DC processor to SignAsyncEnd.

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.

Set Detached to true to generate a detached signature (stored as a separate file).

CAdES defines a number of different 'levels' of signatures. Supported signature levels:

CountersignAsyncEnd Method (CAdESSigner Component)

Completes the asynchronous countersigning operation.

Syntax

void __fastcall CountersignAsyncEnd(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 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.

CountersignExternal Method (CAdESSigner Component)

Countersigns the existing signature using an external signing facility.

Syntax

void __fastcall CountersignExternal(int Level, bool SerialSignature);

Remarks

Use this method to countersign a signature. Use the Level parameter to provide the desired CAdES level (see below). SerialSignature specifies whether the new countersignature should be added on the same level of hierarchy as the original signature (signature-over-data, True), or as a true countersignature (signature-over-signature, False).

Call this method to delegate the low-level signing operation to an external, remote, or custom signing engine. This method is useful if the signature has to be made by a device accessible through a custom or non-standard signing interface.

When all preparations are done and the hash is computed, the component fires ExternalSign event which allows to pass the hash value to the external engine for signing.

CAdES defines a number of different 'levels' of signatures. Supported signature levels:

DoAction Method (CAdESSigner 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 (CAdESSigner 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 (CAdESSigner Component)

Creates a new CAdES signature over the provided data.

Syntax

void __fastcall Sign(int Level, bool Detached);

Remarks

Call this method to produce a new signature of the needed Level over the provided data. Set Detached to true to generate a detached signature (stored as a separate file and not including the data).

CAdES standard defines a number of different 'levels' of signatures. Supported signature levels:

SignAsyncBegin Method (CAdESSigner Component)

Initiates asynchronous (DC) signing.

Syntax

String __fastcall SignAsyncBegin(int Level, bool Detached);

__property TsbxCAdESSignerErrorEvent 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 (CAdESSigner 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;
} TsbxCAdESSignerExternalSignEventParams;
typedef void __fastcall (__closure *TsbxCAdESSignerExternalSignEvent)(System::TObject* Sender, TsbxCAdESSignerExternalSignEventParams *e);
__property TsbxCAdESSignerExternalSignEvent 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 (CAdESSigner Component)

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

Syntax

typedef struct {
  String EventID;
  String EventParam;
} TsbxCAdESSignerNotificationEventParams;
typedef void __fastcall (__closure *TsbxCAdESSignerNotificationEvent)(System::TObject* Sender, TsbxCAdESSignerNotificationEventParams *e);
__property TsbxCAdESSignerNotificationEvent 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 (CAdESSigner 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;
} TsbxCAdESSignerTimestampRequestEventParams;
typedef void __fastcall (__closure *TsbxCAdESSignerTimestampRequestEvent)(System::TObject* Sender, TsbxCAdESSignerTimestampRequestEventParams *e);
__property TsbxCAdESSignerTimestampRequestEvent 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 (CAdESSigner Component)

Fires when a remote TLS party requests a client certificate.

Syntax

typedef struct {
  String Host;
  String CANames;
} TsbxCAdESSignerTLSCertNeededEventParams;
typedef void __fastcall (__closure *TsbxCAdESSignerTLSCertNeededEvent)(System::TObject* Sender, TsbxCAdESSignerTLSCertNeededEventParams *e);
__property TsbxCAdESSignerTLSCertNeededEvent 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 (CAdESSigner 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;
} TsbxCAdESSignerTLSCertValidateEventParams;
typedef void __fastcall (__closure *TsbxCAdESSignerTLSCertValidateEvent)(System::TObject* Sender, TsbxCAdESSignerTLSCertValidateEventParams *e);
__property TsbxCAdESSignerTLSCertValidateEvent 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 (CAdESSigner Component)

Fires when a TLS handshake with Host successfully completes.

Syntax

typedef struct {
  String Host;
  String Version;
  String Ciphersuite;
  DynamicArray ConnectionId;
  bool Abort;
} TsbxCAdESSignerTLSEstablishedEventParams;
typedef void __fastcall (__closure *TsbxCAdESSignerTLSEstablishedEvent)(System::TObject* Sender, TsbxCAdESSignerTLSEstablishedEventParams *e);
__property TsbxCAdESSignerTLSEstablishedEvent 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 (CAdESSigner Component)

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

Syntax

typedef struct {
  String Host;
  bool Abort;
} TsbxCAdESSignerTLSHandshakeEventParams;
typedef void __fastcall (__closure *TsbxCAdESSignerTLSHandshakeEvent)(System::TObject* Sender, TsbxCAdESSignerTLSHandshakeEventParams *e);
__property TsbxCAdESSignerTLSHandshakeEvent 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 (CAdESSigner Component)

Reports the graceful closure of a TLS connection.

Syntax

typedef struct {
  String Host;
} TsbxCAdESSignerTLSShutdownEventParams;
typedef void __fastcall (__closure *TsbxCAdESSignerTLSShutdownEvent)(System::TObject* Sender, TsbxCAdESSignerTLSShutdownEventParams *e);
__property TsbxCAdESSignerTLSShutdownEvent 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 (CAdESSigner 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.
