QString GetExternalCryptoKeyID();
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 extra protection layer for the protocol and diminishes the risk of 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

char* secureblackbox_pdfdecryptor_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.
Decrypt Method (PDFDecryptor Class)
Decrypts a PDF document.
Syntax
ANSI (Cross Platform) int Decrypt(); Unicode (Windows) INT Decrypt();
int secureblackbox_pdfdecryptor_decrypt(void* lpObj);
int Decrypt();
Remarks
Use this method to decrypt a PDF document provided via InputFile (InputStream). The decrypted document will be saved in OutputFile (OutputStream).
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.)
DoAction Method (PDFDecryptor Class)
Performs an additional action.
Syntax
ANSI (Cross Platform) char* DoAction(const char* lpszActionID, const char* lpszActionParams); Unicode (Windows) LPWSTR DoAction(LPCWSTR lpszActionID, LPCWSTR lpszActionParams);
char* secureblackbox_pdfdecryptor_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 insencitive) 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.
DocumentLoaded Event (PDFDecryptor Class)
This event is fired when the document has been loaded into memory.
Syntax
ANSI (Cross Platform) virtual int FireDocumentLoaded(PDFDecryptorDocumentLoadedEventParams *e);
typedef struct {
int Cancel; int reserved; } PDFDecryptorDocumentLoadedEventParams;
Unicode (Windows) virtual INT FireDocumentLoaded(PDFDecryptorDocumentLoadedEventParams *e);
typedef struct {
BOOL Cancel; INT reserved; } PDFDecryptorDocumentLoadedEventParams;
#define EID_PDFDECRYPTOR_DOCUMENTLOADED 1 virtual INT SECUREBLACKBOX_CALL FireDocumentLoaded(BOOL &bCancel);
class PDFDecryptorDocumentLoadedEventParams { public: bool Cancel(); void SetCancel(bool bCancel); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void DocumentLoaded(PDFDecryptorDocumentLoadedEventParams *e);
// Or, subclass PDFDecryptor and override this emitter function. virtual int FireDocumentLoaded(PDFDecryptorDocumentLoadedEventParams *e) {...}
Remarks
The handler for this event is a good place to check the document structure, which may be useful when preparing the signature. For example, you can use the Pages information to find the optimal position for the signature widget.
Set Cancel to true to terminate document processing on this stage.
Encrypted Event (PDFDecryptor Class)
Notifies the application that the document is encrypted and provides recipient certificate details if asymmetric encryption was used to encrypt the document.
Syntax
ANSI (Cross Platform) virtual int FireEncrypted(PDFDecryptorEncryptedEventParams *e);
typedef struct {
int CertUsed;
const char *IssuerRDN;
const char *SerialNumber; int lenSerialNumber;
const char *SubjectKeyID; int lenSubjectKeyID;
int NeedCredential;
int SkipThis; int reserved; } PDFDecryptorEncryptedEventParams;
Unicode (Windows) virtual INT FireEncrypted(PDFDecryptorEncryptedEventParams *e);
typedef struct {
BOOL CertUsed;
LPCWSTR IssuerRDN;
LPCSTR SerialNumber; INT lenSerialNumber;
LPCSTR SubjectKeyID; INT lenSubjectKeyID;
BOOL NeedCredential;
BOOL SkipThis; INT reserved; } PDFDecryptorEncryptedEventParams;
#define EID_PDFDECRYPTOR_ENCRYPTED 2 virtual INT SECUREBLACKBOX_CALL FireEncrypted(BOOL &bCertUsed, LPSTR &lpszIssuerRDN, LPSTR &lpSerialNumber, INT &lenSerialNumber, LPSTR &lpSubjectKeyID, INT &lenSubjectKeyID, BOOL &bNeedCredential, BOOL &bSkipThis);
class PDFDecryptorEncryptedEventParams { public: bool CertUsed(); const QString &IssuerRDN(); const QByteArray &SerialNumber(); const QByteArray &SubjectKeyID(); bool NeedCredential(); bool SkipThis(); void SetSkipThis(bool bSkipThis); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void Encrypted(PDFDecryptorEncryptedEventParams *e);
// Or, subclass PDFDecryptor and override this emitter function. virtual int FireEncrypted(PDFDecryptorEncryptedEventParams *e) {...}
Remarks
The class fires this event when processing encrypted documents to report the fact of encryption and pass certificate parameters to the user.
This event fires repeatedly for each encryption mechanism used in the document until the user provides the correct credential via the DecryptionCertificate or Password property (depending on encryption method used), or sets SkipThis to true.
The CertUsed parameter specifies the encryption method used. If set to true, it indicates that the document uses asymmetric (certificate-based) encryption. In that case the IssuerRDN, SerialNumber, and SubjectKeyID parameters provide the details of the encryption certificate. Note that the document can be encrypted with more than one certificate (or have "more than one recipient"), in which case each certificate will invoke its own OnEncrypted event loop.
CertUsed set to false indicates that the document uses password encryption. In this case, provide the password via the Password property.
The NeedCredential parameter specifies whether the correct credential is already available to the class or still needs to be set. One example where NeedCredential would be set to false is where it had been provided by the application prior to processing the document (e.g. by setting the Password property to a known pre-defined value). If NeedCredential is set to true, you must provide the valid credential for the decryption process to succeed.
Error Event (PDFDecryptor Class)
Information about errors during signing/validation.
Syntax
ANSI (Cross Platform) virtual int FireError(PDFDecryptorErrorEventParams *e);
typedef struct {
int ErrorCode;
const char *Description; int reserved; } PDFDecryptorErrorEventParams;
Unicode (Windows) virtual INT FireError(PDFDecryptorErrorEventParams *e);
typedef struct {
INT ErrorCode;
LPCWSTR Description; INT reserved; } PDFDecryptorErrorEventParams;
#define EID_PDFDECRYPTOR_ERROR 3 virtual INT SECUREBLACKBOX_CALL FireError(INT &iErrorCode, LPSTR &lpszDescription);
class PDFDecryptorErrorEventParams { public: int ErrorCode(); const QString &Description(); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void Error(PDFDecryptorErrorEventParams *e);
// Or, subclass PDFDecryptor and override this emitter function. virtual int FireError(PDFDecryptorErrorEventParams *e) {...}
Remarks
The event is fired in case of exceptional conditions during PDF processing.
ErrorCode contains an error code and Description contains a textual description of the error.
ExternalDecrypt Event (PDFDecryptor Class)
Handles remote or external decryption.
Syntax
ANSI (Cross Platform) virtual int FireExternalDecrypt(PDFDecryptorExternalDecryptEventParams *e);
typedef struct {
const char *OperationId;
const char *Algorithm;
const char *Pars;
const char *EncryptedData;
char *Data; int reserved; } PDFDecryptorExternalDecryptEventParams;
Unicode (Windows) virtual INT FireExternalDecrypt(PDFDecryptorExternalDecryptEventParams *e);
typedef struct {
LPCWSTR OperationId;
LPCWSTR Algorithm;
LPCWSTR Pars;
LPCWSTR EncryptedData;
LPWSTR Data; INT reserved; } PDFDecryptorExternalDecryptEventParams;
#define EID_PDFDECRYPTOR_EXTERNALDECRYPT 4 virtual INT SECUREBLACKBOX_CALL FireExternalDecrypt(LPSTR &lpszOperationId, LPSTR &lpszAlgorithm, LPSTR &lpszPars, LPSTR &lpszEncryptedData, LPSTR &lpszData);
class PDFDecryptorExternalDecryptEventParams { public: const QString &OperationId(); const QString &Algorithm(); const QString &Pars(); const QString &EncryptedData(); const QString &Data(); void SetData(const QString &qsData); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void ExternalDecrypt(PDFDecryptorExternalDecryptEventParams *e);
// Or, subclass PDFDecryptor and override this emitter function. virtual int FireExternalDecrypt(PDFDecryptorExternalDecryptEventParams *e) {...}
Remarks
Assign a handler to this event if you need to delegate a low-level decryption operation to an external, remote, or custom decryption engine. The handler receives a encrypted value in the EncryptedData parameter, and is expected to decrypt it and place the decrypted value into the Data parameter.
OperationId provides a comment about the operation and its origin. It depends on the exact component being used, and may be empty. Algorithm specifies the encryption algorithm being used, and Pars contain algorithm-dependent parameters.
The component uses base16 (hex) encoding for EncryptedData, Data, and Pars parameters. If your decryption engine uses a different input and output encoding, you may need to decode and/or encode the data before and/or after the decryption.
A sample data encoded in base16: a0dee2a0382afbb09120ffa7ccd8a152 - lower case base16 A0DEE2A0382AFBB09120FFA7CCD8A152 - upper case base16
Notification Event (PDFDecryptor Class)
This event notifies the application about an underlying control flow event.
Syntax
ANSI (Cross Platform) virtual int FireNotification(PDFDecryptorNotificationEventParams *e);
typedef struct {
const char *EventID;
const char *EventParam; int reserved; } PDFDecryptorNotificationEventParams;
Unicode (Windows) virtual INT FireNotification(PDFDecryptorNotificationEventParams *e);
typedef struct {
LPCWSTR EventID;
LPCWSTR EventParam; INT reserved; } PDFDecryptorNotificationEventParams;
#define EID_PDFDECRYPTOR_NOTIFICATION 5 virtual INT SECUREBLACKBOX_CALL FireNotification(LPSTR &lpszEventID, LPSTR &lpszEventParam);
class PDFDecryptorNotificationEventParams { 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(PDFDecryptorNotificationEventParams *e);
// Or, subclass PDFDecryptor and override this emitter function. virtual int FireNotification(PDFDecryptorNotificationEventParams *e) {...}
Remarks
The class 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 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.
Config Settings (PDFDecryptor Class)
The class 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 class, access to these internal properties is provided through the Config method.PDFDecryptor Config Settings
