XMLSigner Component

Properties   Methods   Events   Config Settings   Errors  

The XMLSigner component provides a simple interface for digitally signing XML data according to the XML-Signature Syntax and Processing specification.

Syntax

TsbxXMLSigner

Remarks

To sign the data, you need to specify the data to be signed using the References property, then select the signature type and signature method type (signature or MAC).

Set the path to the file to be signed via the InputFile. Signed data will be saved in the OutputFile. Finally, call the Sign method to generate a signature and save signed data. It is possible to generate a signature remotely: use SignExternal method to do this.

Asynchronous signing is also supported. Call SignAsyncBegin to generate a signature and save the generated XML-DSIG without signature value into the document. To complete the signing, call SignAsyncEnd.

XMLSigner only performs basic signing of XML documents. For richer features, such as XAdES and/or chain validation, please see the XAdESSigner component

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

Data Type

String

AddDataReference Method (XMLSigner Component)

Creates a new XML reference to the specified data.

Syntax

int __fastcall AddDataReference(String DataURI, DynamicArray<Byte> Data);

Remarks

Use this method to add a reference to the custom data. Pass the reference's URI via DataURI parameter.

This method uses HashAlgorithm property to specify the hash algorithm of the reference.

The method returns the index of the new reference entry in the References collection.

AddReference Method (XMLSigner Component)

Creates a new XML reference to the specified XML element.

Syntax

int __fastcall AddReference(String TargetXmlElement, String CustomId, bool AutoGenerateId);

Remarks

Use this method to add a reference to a particular XML element.

The reference's URI is set basing on the ID of the XML element. If the XML element doesn't have an ID then a CustomId value will be used. If CustomId is empty and AutoGenerateId is set, the ID will be generated automatically. An exception will be thrown otherwise.

This method uses CanonicalizationMethod and HashAlgorithm properties to specify the canonicalization method and hash algorithm of the reference.

The method returns the index of the new reference entry in the References collection.

Config Method (XMLSigner 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.

DoAction Method (XMLSigner 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 (XMLSigner 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.

GetInnerXML Method (XMLSigner Component)

Get the inner XML content of the selected XML element.

Syntax

String __fastcall GetInnerXML(String XPath);

Remarks

Call this method to get the inner XML content of the selected XML element.

GetOuterXML Method (XMLSigner Component)

Get the outer XML content of the selected XML element.

Syntax

String __fastcall GetOuterXML(String XPath);

Remarks

Call this method to get the outer XML content of the selected XML element.

GetTextContent Method (XMLSigner Component)

Get the text content of the selected XML element.

Syntax

String __fastcall GetTextContent(String XPath);

Remarks

Call this method to get the text content of the selected XML element.

SetTextContent Method (XMLSigner Component)

Set the text content of the selected XML element.

Syntax

void __fastcall SetTextContent(String XPath, String Value);

Remarks

Call this method to set the text content of the selected XML element.

Sign Method (XMLSigner Component)

Signs an XML document.

Syntax

void __fastcall Sign();

Remarks

Call this method to generate a signature over an XML document.

SignAsyncBegin Method (XMLSigner 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 (XMLSigner 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.

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.

SignExternal Method (XMLSigner Component)

Signs the document using an external signing facility.

Syntax

void __fastcall SignExternal();

Remarks

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 hash is computed, the component fires ExternalSign event which allows to pass the hash value for signing.

Error Event (XMLSigner Component)

Reports the details of signing errors.

Syntax

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

Remarks

The event is fired in case of exceptional conditions during signing.

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 XML.

ExternalSign Event (XMLSigner 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;
} TsbxXMLSignerExternalSignEventParams;
typedef void __fastcall (__closure *TsbxXMLSignerExternalSignEvent)(System::TObject* Sender, TsbxXMLSignerExternalSignEventParams *e);
__property TsbxXMLSignerExternalSignEvent 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(); };

FormatElement Event (XMLSigner Component)

Reports the XML element that is currently being processed.

Syntax

typedef struct {
  String StartTagWhitespace;
  String EndTagWhitespace;
  int Level;
  String Path;
  bool HasChildElements;
} TsbxXMLSignerFormatElementEventParams;
typedef void __fastcall (__closure *TsbxXMLSignerFormatElementEvent)(System::TObject* Sender, TsbxXMLSignerFormatElementEventParams *e);
__property TsbxXMLSignerFormatElementEvent OnFormatElement = { read=FOnFormatElement, write=FOnFormatElement };

Remarks

Path and Level specify the path to the XML element being processed and its nesting level, respectively.

HasChildElements specify if processed XML element has child elements.

Among other purposes, this event may be used to add whitespace formatting before or after a particular element in the signature.

FormatText Event (XMLSigner Component)

Reports XML text that is currently being processed.

Syntax

typedef struct {
  String Text;
  int TextType;
  int Level;
  String Path;
} TsbxXMLSignerFormatTextEventParams;
typedef void __fastcall (__closure *TsbxXMLSignerFormatTextEvent)(System::TObject* Sender, TsbxXMLSignerFormatTextEventParams *e);
__property TsbxXMLSignerFormatTextEvent OnFormatText = { read=FOnFormatText, write=FOnFormatText };

Remarks

TextType parameter specifies the type of the XML text (normal or Base64-encoded) that is stored in the element; Path and Level specify the path to the XML element and its nesting level.

Among other purposes, this event may be used to add whitespace formatting before or after a particular element in the signature.

Notification Event (XMLSigner Component)

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

Syntax

typedef struct {
  String EventID;
  String EventParam;
} TsbxXMLSignerNotificationEventParams;
typedef void __fastcall (__closure *TsbxXMLSignerNotificationEvent)(System::TObject* Sender, TsbxXMLSignerNotificationEventParams *e);
__property TsbxXMLSignerNotificationEvent 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.

ResolveReference Event (XMLSigner Component)

Asks the application to resolve a reference.

Syntax

typedef struct {
  int ReferenceIndex;
  String URI;
} TsbxXMLSignerResolveReferenceEventParams;
typedef void __fastcall (__closure *TsbxXMLSignerResolveReferenceEvent)(System::TObject* Sender, TsbxXMLSignerResolveReferenceEventParams *e);
__property TsbxXMLSignerResolveReferenceEvent OnResolveReference = { read=FOnResolveReference, write=FOnResolveReference };

Remarks

This event is fired when the control could not automatically resolve a reference and requires custom treatment.

URI contains a reference to the data.

ReferenceIndex specifies the index of the reference to process.

Based on the reference's URI the event handler should set either TargetXMLElement or TargetData property of the reference.

Config Settings (XMLSigner 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.
