int SetExternalCryptoKeyID(QString qsExternalCryptoKeyID);

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:

 
 Copy
  signer.ExternalCrypto.KeyID = "MainSigningKey";
  signer.ExternalCrypto.KeySecret = "abcdef0123456789";

Data Type

String

char* secureblackbox_officequicksigner_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.

DoAction Method (OfficeQuickSigner Class)

char* secureblackbox_officequicksigner_doaction(void* lpObj, const char* lpszActionID, const char* lpszActionParams);

QString DoAction(const QString& qsActionID, const QString& qsActionParams);

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;....

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.

ExtractAsyncData Method (OfficeQuickSigner Class)

Extracts user data from the DC signing service response.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* ExtractAsyncData(const char* lpszAsyncReply);

Unicode (Windows)
LPWSTR ExtractAsyncData(LPCWSTR lpszAsyncReply);

char* secureblackbox_officequicksigner_extractasyncdata(void* lpObj, const char* lpszAsyncReply);

QString ExtractAsyncData(const QString& qsAsyncReply);

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.

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.

Sign Method (OfficeQuickSigner Class)

Calculates the signature value.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int Sign();

Unicode (Windows)
INT Sign();

int secureblackbox_officequicksigner_sign(void* lpObj);

int Sign();

Remarks

Call this method to generate a signature over the document.

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.)

SignAsyncBegin Method (OfficeQuickSigner Class)

Initiates the asynchronous signing operation.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* SignAsyncBegin();

Unicode (Windows)
LPWSTR SignAsyncBegin();

char* secureblackbox_officequicksigner_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 (OfficeQuickSigner 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_officequicksigner_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.

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 (OfficeQuickSigner Class)

Signs the document using an external signing facility.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int SignExternal();

Unicode (Windows)
INT SignExternal();

int secureblackbox_officequicksigner_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 (OfficeQuickSigner Class)

Information about errors during signing.

Syntax

• C++
• C
• Qt

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

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


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

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

#define EID_OFFICEQUICKSIGNER_ERROR 1

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

class OfficeQuickSignerErrorEventParams {
public:
  int ErrorCode();

  const QString &Description();

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

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

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

Remarks

This event is fired in case of exceptional conditions during the office document processing.

ErrorCode contains an error code and Description contains a textual description of the error.

ExternalSign Event (OfficeQuickSigner Class)

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

Syntax

• C++
• C
• Qt

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

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


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

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

#define EID_OFFICEQUICKSIGNER_EXTERNALSIGN 2

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

class OfficeQuickSignerExternalSignEventParams {
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(OfficeQuickSignerExternalSignEventParams *e);

// Or, subclass OfficeQuickSigner and override this emitter function.
virtual int FireExternalSign(OfficeQuickSignerExternalSignEventParams *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();
};

Notification Event (OfficeQuickSigner Class)

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

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireNotification(OfficeQuickSignerNotificationEventParams *e);

typedef struct {
  const char *EventID;
  const char *EventParam;
  int reserved;
} OfficeQuickSignerNotificationEventParams;


Unicode (Windows)
virtual INT FireNotification(OfficeQuickSignerNotificationEventParams *e);

typedef struct {
  LPCWSTR EventID;
  LPCWSTR EventParam;
  INT reserved;
} OfficeQuickSignerNotificationEventParams;

#define EID_OFFICEQUICKSIGNER_NOTIFICATION 3

virtual INT SECUREBLACKBOX_CALL FireNotification(LPSTR &lpszEventID, LPSTR &lpszEventParam);

class OfficeQuickSignerNotificationEventParams {
public:
  const QString &EventID();

  const QString &EventParam();

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

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

// Or, subclass OfficeQuickSigner and override this emitter function.
virtual int FireNotification(OfficeQuickSignerNotificationEventParams *e) {...}

Remarks

The class fires this event to let the application know about some event, occurrence, or milestone in the class. 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 class, the exact action it is performing, or the document being processed, one or both may be omitted.

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