This method carries out a lot of work and fires a number of events during its execution. Before the compression process starts, PrepareFile event fires repeatedly to provide the summary of what is being included into the archive. A handler of that event is a good place to make last-minute modifications to the data sources, file names, and actions to take upon the files.

Compression of each entry is surrounded with BeforeCompressFile and AfterCompressFile "brackets". Subscribe to BeforeCompressFile to supply the file contents for entries with Buffer and Stream data sources. AfterCompressFile is a good place to release the content stream alloated in the BeforeCompressFile event handler.

Progress event fires repeatedly to report the progress of the current and whole operations. It also provides an opportunity to abort the compression process.

// To handle, connect one or more slots to this signal. void BeforeCompressFile(ArchiveWriterBeforeCompressFileEventParams *e);
// Or, subclass ArchiveWriter and override this emitter function. virtual int FireBeforeCompressFile(ArchiveWriterBeforeCompressFileEventParams *e) {...}

Remarks

Subscribe to this event to be notified about the start of compression of an archive entry. The handler of this event is a good place to prepare the desired data source.

The Path parameter indicates the path to the extracted entry in the archive. The FileSize specifies the size of the file before compression. Use this event handler to adjust the data source if the file is to be loaded from a stream or buffer. The DataSource parameter indicates the type of the data media:

fdsFile (0)The data will be taken from a file indicated by the entry's LocalPath setting. You can change this path in the handler of this event.
fdsStream (1)The file data will be taken from a stream assigned to FileStream property.
fdsBuffer (2)The data will be taken from a buffer attached to the FileData property.
If passing the data from a stream or buffer, use AfterCompressFile to dispose of any objects allocated in this event handler (such as the source stream).

Use PrepareFile event to adjust the file data source on the fly.

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

Notification Event (ArchiveWriter Class)

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

Syntax

ANSI (Cross Platform)
virtual int FireNotification(ArchiveWriterNotificationEventParams *e);
typedef struct {
const char *EventID;
const char *EventParam; int reserved; } ArchiveWriterNotificationEventParams;
Unicode (Windows) virtual INT FireNotification(ArchiveWriterNotificationEventParams *e);
typedef struct {

};
// To handle, connect one or more slots to this signal. void Notification(ArchiveWriterNotificationEventParams *e);
// Or, subclass ArchiveWriter and override this emitter function. virtual int FireNotification(ArchiveWriterNotificationEventParams *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.

PrepareFile Event (ArchiveWriter Class)

Fires for every file to be compressed before the compression starts.

Syntax

ANSI (Cross Platform)
virtual int FirePrepareFile(ArchiveWriterPrepareFileEventParams *e);
typedef struct {
const char *Path;
int64 FileSize;
int DataSource;
char *LocalPath;
int Action; int reserved; } ArchiveWriterPrepareFileEventParams;

};
// To handle, connect one or more slots to this signal. void PrepareFile(ArchiveWriterPrepareFileEventParams *e);
// Or, subclass ArchiveWriter and override this emitter function. virtual int FirePrepareFile(ArchiveWriterPrepareFileEventParams *e) {...}

Remarks

Class fires this event for every file included in the Files collection before commencing the compression. This is the last opportunity for your code to adjust the action to be taken for each file and tune up the data sources appropriately.

The Path parameter contains the path to the file within the archive (such as Photos/myphoto.jpg), and the FileSize contains the size of that file before compression.

The DataSource parameter indicates the media from which the file contents is to be taken. A typical default value if fdsFile, but you can adjust the value of that parameter if you need to use an alternative source. The following options are available:

fdsFile (0)The data will be taken from a file indicated by the LocalPath parameter. You can change this path in this event handler.
fdsStream (1)The file data will be taken from a stream assigned to FileStream property.
fdsBuffer (2)The data will be taken from a buffer attached to the FileData property.
Please do not assign FileStream or FileData in this event handler: this should be done further down the road in the BeforeCompressFile event handler. The purpose of this event is to prepare the compression plan by summarizing what should be done and to which files.

The Action parameter, which is also tuneable, indicates the action for class to take on the file:

atAdd (0)Add the file to the archive
atKeep (1)Keep the existing file in the archive
atUpdate (2)Update the archived file with a fresher copy
atDelete (3)Delete the file from the archive
atExtract (4)Extract the file (extraction only)
atSkip (5)Skip file extraction (extraction only)

Progress Event (ArchiveWriter Class)

Reports the progress of data compression.

Syntax

ANSI (Cross Platform)
virtual int FireProgress(ArchiveWriterProgressEventParams *e);
typedef struct {
int64 Processed;
int64 Total;
int64 OverallProcessed;
int64 OverallTotal;
int Cancel; int reserved; } ArchiveWriterProgressEventParams;
Unicode (Windows) virtual INT FireProgress(ArchiveWriterProgressEventParams *e);
typedef struct {
LONG64 Processed;
LONG64 Total;
LONG64 OverallProcessed;
LONG64 OverallTotal;
BOOL Cancel; INT reserved; } ArchiveWriterProgressEventParams;
#define EID_ARCHIVEWRITER_PROGRESS 7

virtual INT SECUREBLACKBOX_CALL FireProgress(LONG64 &lProcessed, LONG64 &lTotal, LONG64 &lOverallProcessed, LONG64 &lOverallTotal, BOOL &bCancel);
class ArchiveWriterProgressEventParams {
public:
  qint64 Processed();

  qint64 Total();

  qint64 OverallProcessed();

  qint64 OverallTotal();

  bool Cancel();
  void SetCancel(bool bCancel);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void Progress(ArchiveWriterProgressEventParams *e);
// Or, subclass ArchiveWriter and override this emitter function. virtual int FireProgress(ArchiveWriterProgressEventParams *e) {...}

Remarks

Subscribe to this event to be notified about compression progress.

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

RecipientFound Event (ArchiveWriter Class)

Signifies that the archive was found to be encrypted with a digital certificate.

Syntax

ANSI (Cross Platform)
virtual int FireRecipientFound(ArchiveWriterRecipientFoundEventParams *e);
typedef struct {
const char *PublicKeyHash; int lenPublicKeyHash;
int CertFound; int reserved; } ArchiveWriterRecipientFoundEventParams;
Unicode (Windows) virtual INT FireRecipientFound(ArchiveWriterRecipientFoundEventParams *e);
typedef struct {
LPCSTR PublicKeyHash; INT lenPublicKeyHash;
BOOL CertFound; INT reserved; } ArchiveWriterRecipientFoundEventParams;
#define EID_ARCHIVEWRITER_RECIPIENTFOUND 8

virtual INT SECUREBLACKBOX_CALL FireRecipientFound(LPSTR &lpPublicKeyHash, INT &lenPublicKeyHash, BOOL &bCertFound);
class ArchiveWriterRecipientFoundEventParams {
public:
  const QByteArray &PublicKeyHash();

  bool CertFound();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void RecipientFound(ArchiveWriterRecipientFoundEventParams *e);
// Or, subclass ArchiveWriter and override this emitter function. virtual int FireRecipientFound(ArchiveWriterRecipientFoundEventParams *e) {...}

Remarks

The class fires this event to notify the application that the archive was found to be encrypted with a digital certificate. The hash of the certificate's public key is provided in the PublicKeyHash parameter.

CertFound indicates whether a certificate with a matching public key hash was found in the DecryptionCertificates list. If it wasn't, you need to locate it on the system and add it to that list: class won't be able to decrypt the archive otherwise.

Please note that the certificate must have an associated private key to be capable of decryption.

SecureBlackboxStream Type

Syntax

SecureBlackboxStream (declared in secureblackbox.h)

Remarks

The ArchiveWriter class includes one or more API members that take a stream object as a parameter. To use such API members, create a concrete class that implements the SecureBlackboxStream interface and pass the ArchiveWriter class an instance of that concrete class.

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.

Properties

CanRead Whether the stream supports reading.

bool CanRead() { return true; }
CanSeek Whether the stream supports seeking.

bool CanSeek() { return true; }
CanWrite Whether the stream supports writing.

bool CanWrite() { return true; }
Length Gets the length of the stream, in bytes.

int64 GetLength() = 0;

Methods

Close Closes the stream, releasing all resources currently allocated for it.

void Close() {}

This method is called automatically when a SecureBlackboxStream object is deleted.

Flush Forces all data held by the stream's buffers to be written out to storage.

int Flush() { return 0; }

Must return 0 if flushing is successful; or -1 if an error occurs or the stream is closed. If the stream does not support writing, this method must do nothing and return 0.

Read Reads a sequence of bytes from the stream and advances the current position within the stream by the number of bytes read.

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

Buffer specifies the buffer to populate with data from the stream. Count specifies the number of bytes that should be read from the stream.

Must return the total number of bytes read into Buffer; this may be less than Count if that many bytes are not currently available, or 0 if the end of the stream has been reached. Must return -1 if an error occurs, if reading is not supported, or if the stream is closed.

Seek Sets the current position within the stream based on a particular point of origin.

int64 Seek(int64 offset, int seekOrigin) = 0;

Offset specifies the offset in the stream to seek to, relative to SeekOrigin. Valid values for SeekOrigin are:

  • 0: Seek from beginning.
  • 1: Seek from current position.
  • 2: Seek from end.

Must return the new position within the stream; or -1 if an error occurs, if seeking is not supported, or if the stream is closed (however, see note below). If -1 is returned, the current position within the stream must remain unchanged.

Note: If the stream is not closed, it must always be possible to call this method with an Offset of 0 and a SeekOrigin of 1 to obtain the current position within the stream, even if seeking is not otherwise supported.

Write Writes a sequence of bytes to the stream and advances the current position within the stream by the number of bytes written.

int Write(const void* buffer, int count) = 0;

Buffer specifies the buffer with data to write to the stream. Count specifies the number of bytes that should be written to the stream.

Must return the total number of bytes written to the stream; this may be less than Count if that many bytes could not be written. Must return -1 if an error occurs, if writing is not supported, or if the stream is closed.

Config Settings (ArchiveWriter 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.

ArchiveWriter Config Settings

TempPath:   Path for storing temporary files.

This setting specifies an absolute path to the location on disk where temporary files are stored.

UsePax:   Enables use of PAX algorithm when creating TAR directories.

Use this setting to enable or disable the use of PAX algorithm when TARring directories.

UseUStar:   Enables use of UStar variant of file name packaging when creating TAR directories.

Use this setting to enable or disable the use of UStar file name encoding format. This format allows for correct saving of path names longer than 99 characters in TAR archives.

Base Config Settings

CheckKeyIntegrityBeforeUse:   Enables or disable private key integrity check before use.

This global property enables or disables private key material check before each signing operation. This slows down performance a bit, but prevents a selection of attacks on RSA keys where keys with unknown origins are used.

You can switch this property off to improve performance if your project only uses known, good private keys.

CookieCaching:   Specifies whether a cookie cache should be used for HTTP(S) transports.

Set this property to enable or disable cookies caching for the class.

Supported values are:

offNo caching (default)

Use this property to get cookies from the internal cookie storage of the class and/or restore them back between application sessions.

DefDeriveKeyIterations:   Specifies the default key derivation algorithm iteration count.

This global property sets the default number of iterations for all supported key derivation algorithms. Note that you can provide the required number of iterations by using properties of the relevant key generation component; this global setting is used in scenarios where specific iteration count is not or cannot be provided.

EnableClientSideSSLFFDHE:   Enables or disables finite field DHE key exchange support in TLS clients.

This global property enables or disables support for finite field DHE key exchange methods in TLS clients. FF DHE is a slower algorithm if compared to EC DHE; enabling it may result in slower connections.

This setting only applies to sessions negotiated with TLS version 1.3.

GlobalCookies:   Gets or sets global cookies for all the HTTP transports.

Use this property to get cookies from the GLOBAL cookie storage or restore them back between application sessions. These cookies will be used by all the classes that have its CookieCaching property set to "global".

noneNo flush (caching only)
immediateImmediate flush (real-time logging)
maxcountFlush cached entries upon reaching LogMaxEventCount entries in the cache.

LogLevel:   Specifies the debug log level.

Use this property to provide the desired debug log level.

Supported values are:

noneNone (by default)
fatalSevere errors that cause premature termination.
errorOther runtime errors or unexpected conditions.
warningUse of deprecated APIs, poor use of API, 'almost' errors, other runtime situations that are undesirable or unexpected, but not necessarily "wrong".
infoInteresting runtime events (startup/shutdown).
debugDetailed information on flow of through the system.
traceMore detailed information.

LogMaxEventCount:   Specifies the maximum number of events to cache before further action is taken.

Use this property to specify the log event number threshold. This threshold may have different effects, depending on the rotation setting and/or the flush mode.

Use this property to set the log rotation mode. The following values are defined:

noneNo rotation
deleteolderDelete older entries from the cache upon reaching LogMaxEventCount
keepolderKeep older entries in the cache upon reaching LogMaxEventCount (newer entries are discarded)

MaxASN1BufferLength:   Specifies the maximal allowed length for ASN.1 primitive tag data.

This global property limits the maximal allowed length for ASN.1 tag data for non-content-carrying structures, such as certificates, CRLs, or timestamps. It does not affect structures that can carry content, such as CMS/CAdES messages. This is a security property aiming at preventing DoS attacks.

MaxASN1TreeDepth:   Specifies the maximal depth for processed ASN.1 trees.

This global property limits the maximal depth of ASN.1 trees that the component can handle without throwing an error. This is a security property aiming at preventing DoS attacks.

OCSPHashAlgorithm:   Specifies the hash algorithm to be used to identify certificates in OCSP requests.

This global setting defines the hash algorithm to use in OCSP requests during chain validation. Some OCSP responders can only use older algorithms, in which case setting this property to SHA1 may be helpful.

StaticDNS:   Specifies whether static DNS rules should be used.

Set this property to enable or disable static DNS rules for the class. Works only if UseOwnDNSResolver is set to true.

Supported values are:

noneNo static DNS rules (default)
localLocal static DNS rules
globalGlobal static DNS rules

StaticIPAddress[domain]:   Gets or sets an IP address for the specified domain name.

Use this property to get or set an IP address for the specified domain name in the internal (of the class) or global DNS rules storage depending on the StaticDNS value. The type of the IP address (IPv4 or IPv6) is determined automatically. If both addresses are available, they are devided by the | (pipe) character.

StaticIPAddresses:   Gets or sets all the static DNS rules.

Use this property to get static DNS rules from the current rules storage or restore them back between application sessions. If StaticDNS of the class is set to "local", the property returns/restores the rules from/to the internal storage of the class. If StaticDNS of the class is set to "global", the property returns/restores the rules from/to the GLOBAL storage. The rules list is returned and accepted in JSON format.

Tag:   Allows to store any custom data.

Use this config property to store any custom data.

TLSSessionGroup:   Specifies the group name of TLS sessions to be used for session resumption.

Use this property to limit the search of chached TLS sessions to the specified group. Sessions from other groups will be ignored. By default, all sessions are cached with an empty group name and available to all the classes.

TLSSessionLifetime:   Specifies lifetime in seconds of the cached TLS session.

Use this property to specify how much time the TLS session should be kept in the session cache. After this time, the session expires and will be automatically removed from the cache. Default value is 300 seconds (5 minutes).

TLSSessionPurgeInterval:   Specifies how often the session cache should remove the expired TLS sessions.

Use this property to specify the time interval of purging the expired TLS sessions from the session cache. Default value is 60 seconds (1 minute).

UseOwnDNSResolver:   Specifies whether the client components should use own DNS resolver.

Set this global property to false to force all the client components to use the DNS resolver provided by the target OS instead of using own one.

UseSharedSystemStorages:   Specifies whether the validation engine should use a global per-process copy of the system certificate stores.

Set this global property to false to make each validation run use its own copy of system certificate stores.

UseSystemOAEPAndPSS:   Enforces or disables the use of system-driven RSA OAEP and PSS computations.

This global setting defines who is responsible for performing RSA-OAEP and RSA-PSS computations where the private key is stored in a Windows system store and is exportable. If set to true, SBB will delegate the computations to Windows via a CryptoAPI call. Otherwise, it will export the key material and perform the computations using its own OAEP/PSS implementation.

This setting only applies to certificates originating from a Windows system store.

UseSystemRandom:   Enables or disables the use of the OS PRNG.

Use this global property to enable or disable the use of operating system-driven pseudorandom number generation.

Trappable Errors (ArchiveWriter Class)

Error Handling (C++)

Call the GetLastErrorCode() method to obtain the last called method's result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. Known error codes are listed below. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.
