XMLSigner Class

Properties   Methods   Events   Config Settings   Errors  

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

Syntax

XMLSigner

Remarks

XMLSigner implements the most basic XML-SIG signature standard. While this format is still quite widely used, it lacks important facilities that have been gaining popularity in recent years, such as strict chain validation, support for trust environments, and long-term signatures (also known as XAdES). If you are looking for XAdES support, please consider using the alternative XAdESSigner component.

To sign XML data with XMLSigner, you need to specify the data to be signed using the References property first, then select the signature type and signature method type (signature or MAC). References are individual pieces of the XML document that are covered by the signature. You can choose to sign the whole document or one or more individual elements.

Set the path to the file to be signed via the InputFile (or InputBytes). Signed data will be saved in OutputBytes, or the OutputFile if provided.

Finally, call the Sign method to generate a signature and save the signed data. XMLSigner supports the two product-wide external signing approaches for signing with remote private keys: use SignExternal or SignAsyncBegin to do this as required.

 
 Copy
  XmlSigner.InputFile = "data.xml";
  XmlSigner.OutputFile = "data-signed.xml";
  XmlSigner.SigningCertificate = CertMgr.Certificate;
  XmlSigner.Sign();

int AddReference(const QString& qsTargetXmlElement, const QString& qsCustomId, bool bAutoGenerateId);

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.

Error Handling (C++)

This method returns an Integer value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

Config Method (XMLSigner Class)

Sets or retrieves a configuration setting.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* Config(const char* lpszConfigurationString);

Unicode (Windows)
LPWSTR Config(LPCWSTR lpszConfigurationString);

char* secureblackbox_xmlsigner_config(void* lpObj, const char* lpszConfigurationString);

QString Config(const QString& qsConfigurationString);

Remarks

Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, 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.

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

Remarks

DoAction is a generic method available in every class. 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;....

Common ActionIDs:

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution.

SignAsyncBegin Method (XMLSigner Class)

Initiates the asynchronous signing operation.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* SignAsyncBegin();

Unicode (Windows)
LPWSTR SignAsyncBegin();

char* secureblackbox_xmlsigner_signasyncbegin(void* lpObj);

QString 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 class), which processes it and produces a matching signature state. The async state produced by the server is then passed to the SignAsyncEnd method.

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

SignAsyncEnd Method (XMLSigner Class)

Completes the asynchronous signing operation.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int SignAsyncEnd(const char* lpszAsyncReply);

Unicode (Windows)
INT SignAsyncEnd(LPCWSTR lpszAsyncReply);

int secureblackbox_xmlsigner_signasyncend(void* lpObj, const char* lpszAsyncReply);

int SignAsyncEnd(const QString& qsAsyncReply);

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 class), which processes it and produces a matching signature state. The async state produced by the server is then passed to the SignAsyncEnd method.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

SignExternal Method (XMLSigner Class)

Signs the document using an external signing facility.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int SignExternal();

Unicode (Windows)
INT SignExternal();

int secureblackbox_xmlsigner_signexternal(void* lpObj);

int 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 class fires ExternalSign event which allows to pass the hash value for signing.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

Error Event (XMLSigner Class)

Reports the details of signing errors.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireError(XMLSignerErrorEventParams *e);

typedef struct {
  int ErrorCode;
  const char *Description;
  int reserved;
} XMLSignerErrorEventParams;


Unicode (Windows)
virtual INT FireError(XMLSignerErrorEventParams *e);

typedef struct {
  INT ErrorCode;
  LPCWSTR Description;
  INT reserved;
} XMLSignerErrorEventParams;

#define EID_XMLSIGNER_ERROR 1

virtual INT SECUREBLACKBOX_CALL FireError(INT &iErrorCode, LPSTR &lpszDescription);

class XMLSignerErrorEventParams {
public:
  int ErrorCode();

  const QString &Description();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void Error(XMLSignerErrorEventParams *e);

// Or, subclass XMLSigner and override this emitter function.
virtual int FireError(XMLSignerErrorEventParams *e) {...}

Remarks

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

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireExternalSign(XMLSignerExternalSignEventParams *e);

typedef struct {
  const char *OperationId;
  const char *HashAlgorithm;
  const char *Pars;
  const char *Data;
  char *SignedData;
  int reserved;
} XMLSignerExternalSignEventParams;


Unicode (Windows)
virtual INT FireExternalSign(XMLSignerExternalSignEventParams *e);

typedef struct {
  LPCWSTR OperationId;
  LPCWSTR HashAlgorithm;
  LPCWSTR Pars;
  LPCWSTR Data;
  LPWSTR SignedData;
  INT reserved;
} XMLSignerExternalSignEventParams;

#define EID_XMLSIGNER_EXTERNALSIGN 2

virtual INT SECUREBLACKBOX_CALL FireExternalSign(LPSTR &lpszOperationId, LPSTR &lpszHashAlgorithm, LPSTR &lpszPars, LPSTR &lpszData, LPSTR &lpszSignedData);

class XMLSignerExternalSignEventParams {
public:
  const QString &OperationId();

  const QString &HashAlgorithm();

  const QString &Pars();

  const QString &Data();

  const QString &SignedData();
  void SetSignedData(const QString &qsSignedData);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void ExternalSign(XMLSignerExternalSignEventParams *e);

// Or, subclass XMLSigner and override this emitter function.
virtual int FireExternalSign(XMLSignerExternalSignEventParams *e) {...}

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 class via the SignedData parameter.

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

The class 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:

 
 Copy
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();
};
