The ArchiveReader class supports inspection and extraction of files from zip, tar, gzip and bzip2 archives.

Syntax

ArchiveReader

Remarks

ArchiveReader offers capabilities of inspecting, editing, and unpacking archived files from a variety of archive formats. ArchiveReader archiveReader = new ArchiveReader(); archiveReader.setDecryptionPassword("MyPassword"); // the decryption password for the archive // Opens the archive file, first param is the archive type and the second one the path of the archive archiveReader.open(ArchiveReader.aftZip,"C:/MyArchives/folder.zip"); // extract all the files to the path provided archiveReader.extractAll("C:/Extracted/extractedFolder");

The following common archive formats are supported:

• ZIP (.zip)
• GZip (.gz)
• BZip2 (.bz2)
• Tar+GZip (.tar.gz)
• Tar+Bzip2 (.tar.bz2)

Working with ArchiveReader

Opening the archive.

On this step the component loads the provided compressed data into its memory. You can pass the compressed data as a byte array (OpenBytes), as a stream (OpenStream), or load it from a disk file (Open).

Inspecting the archive contents

Use the Files collection to access information about individual files stored in the opened archive. On this stage you can adjust the individual files objects' ACTION> and DATASOURCE> properties to configure bespoke processing for specific files.

Extracting the files

Call ExtractAll to initiate extraction of all the files contained in the archive and selected using the ACTION> property, or Extract to extract a single file. The component notifies your code about each individual extraction using its BeforeExtractFile and AfterExtractFile events. You can use BeforeExtractFile to provide your final decision about the extraction of a particular file.

Use DecryptionPassword property to specify a decryption password for an archive and/or a specific entry within it. If the password is required but wasn't set, or if the provided password is wrong, the component will fire the DecryptionPasswordNeeded event. This event is fired repeatedly until the correct password is provided or its Cancel parameter is returned as true.

Closing the archive

Once you are finished with the archive, call the component's Close method to close the archive file and release the associated memory.

Close Method (ArchiveReader Class)

Closes the current archive.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int Close();

Unicode (Windows)
INT Close();

int secureblackbox_archivereader_close(void* lpObj);

int Close();

Remarks

Use this method to close the archive that is currently opened and release the associated memory. You won't be able to extract files or access the archive details after closing the archive.

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.)

Config Method (ArchiveReader 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_archivereader_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 (ArchiveReader Class)

Performs an additional action.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* DoAction(const char* lpszActionID, const char* lpszActionParams);

char* secureblackbox_archivereader_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;....

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. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

Extract Method (ArchiveReader Class)

Extracts a single file from the archive.

Syntax

int secureblackbox_archivereader_extract(void* lpObj, const char* lpszPath, const char* lpszLocalPath, int bPreserveFullPath);

int Extract(const QString& qsPath, const QString& qsLocalPath, bool bPreserveFullPath);

Remarks

Use this method to extract a single file from the archive.

Pass the internal path to the entry in the archive via the Path parameter, and the path where to save the extracted entry via the LocalPath parameter. Set PreserveFullPath to true to enforce full-path extraction, in which case LocalPath would indicate the mount point at which the full Path needs to be rooted. If PreserveFullPath is false, the LocalPath provides the final location for the extracted file.

Use ExtractAll to extract all files at once.

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.)

ExtractAll Method (ArchiveReader Class)

Extract all the files contained in the archive.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int ExtractAll(const char* lpszOutputPath);

int secureblackbox_archivereader_extractall(void* lpObj, const char* lpszOutputPath);

int ExtractAll(const QString& qsOutputPath);

Remarks

Use this method to extract all the files contained in the archive file. Pass the path where the extracted files should be saved via the OutputPath parameter.

You can cherry-pick the files to extract, as well as choose different extraction destinations (including files at custom locations, streams, or memory buffers) by subscribing to BeforeExtractFile and AfterExtractFile events.

Use Extract to extract a single file.

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.)

void Progress(ArchiveReaderProgressEventParams *e);

// Or, subclass ArchiveReader and override this emitter function.
virtual int FireProgress(ArchiveReaderProgressEventParams *e) {...}

Remarks

Subscribe to this event to be notified about decompression progress.

Processed and Total report the progress of extraction of the current entry; OverallProcessed and OverallTotal report the progress of the whole operation. Set Cancel to true to stop the operation.

RecipientFound Event (ArchiveReader Class)

Informs the application that an archive is encrypted with a digital certificate.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireRecipientFound(ArchiveReaderRecipientFoundEventParams *e);

};

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

// Or, subclass ArchiveReader and override this emitter function.
virtual int FireRecipientFound(ArchiveReaderRecipientFoundEventParams *e) {...}

Remarks

The class fires this event when processing archives encrypted with an X.509 certificate. CertFound indicates whether the matching certificate has been found in DecryptionCertificates collection. The PublicKeyHash contains the hash (fingerprint) of the certificate's public key.

This event is an opportunity to add the decryption certificate on a later stage if it was not known at the start of the processing.

SignatureFound Event (ArchiveReader Class)

Signifies the start of signature validation.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireSignatureFound(ArchiveReaderSignatureFoundEventParams *e);

typedef struct {
  LPCWSTR IssuerRDN;
  LPCSTR SerialNumber;
  INT lenSerialNumber;
  LPCSTR SubjectKeyID;
  INT lenSubjectKeyID;
  BOOL CertFound;
  BOOL ValidateSignature;
  BOOL ValidateChain;
  INT reserved;
} ArchiveReaderSignatureFoundEventParams;

#define EID_ARCHIVEREADER_SIGNATUREFOUND 9

virtual INT SECUREBLACKBOX_CALL FireSignatureFound(LPSTR &lpszIssuerRDN, LPSTR &lpSerialNumber, INT &lenSerialNumber, LPSTR &lpSubjectKeyID, INT &lenSubjectKeyID, BOOL &bCertFound, BOOL &bValidateSignature, BOOL &bValidateChain);

class ArchiveReaderSignatureFoundEventParams {
public:
  const QString &IssuerRDN();

  const QByteArray &SerialNumber();

  const QByteArray &SubjectKeyID();

  bool CertFound();

  bool ValidateSignature();
  void SetValidateSignature(bool bValidateSignature);

  bool ValidateChain();
  void SetValidateChain(bool bValidateChain);

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

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

// Or, subclass ArchiveReader and override this emitter function.
virtual int FireSignatureFound(ArchiveReaderSignatureFoundEventParams *e) {...}

Remarks

This event tells the application that signature validation is about to start, and provides the details about the signer's certificate via its IssuerRDN, SerialNumber, and SubjectKeyID parameters. It fires for every signature located in the verified document or message.

The CertFound parameter is set to True if the class has found the needed certificate in one of the known locations, and to False otherwise, in which case you must provide it manually via the KnownCertificates property.

Signature validation consists of two independent stages: cryptographic signature validation and chain validation. Separate validation results are reported for each, with the SignatureValidationResult and ChainValidationResult properties respectively.

Use the ValidateSignature and ValidateChain parameters to tell the verifier which stages to include in the validation.

When implementing the SecureBlackboxStream interface's properties and methods, they must behave as described below. If the concrete class's implementation does not behave as expected, undefined behavior may occur.

bool CanRead() { return true; }

bool CanSeek() { return true; }

bool CanWrite() { return true; }

int64 GetLength() = 0;

void Close() {}

int Flush() { return 0; }

int Read(void* buffer, int count) = 0;
