Remarks

Component 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 component 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 Component)

Reports the progress of data compression.

Syntax

public event OnProgressHandler OnProgress;

public delegate void OnProgressHandler(object sender, ArchivewriterProgressEventArgs e);

public class ArchivewriterProgressEventArgs : EventArgs {
  public long Processed { get; }
  public long Total { get; }
  public long OverallProcessed { get; }
  public long OverallTotal { get; }
  public bool Cancel { get; set; }
}
Public Event OnProgress As OnProgressHandler

Public Delegate Sub OnProgressHandler(sender As Object, e As ArchivewriterProgressEventArgs)

Public Class ArchivewriterProgressEventArgs Inherits EventArgs
  Public ReadOnly Property Processed As Long
  Public ReadOnly Property Total As Long
  Public ReadOnly Property OverallProcessed As Long
  Public ReadOnly Property OverallTotal As Long
  Public Property Cancel As Boolean
End Class

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 Component)

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

Syntax

public event OnRecipientFoundHandler OnRecipientFound;

public delegate void OnRecipientFoundHandler(object sender, ArchivewriterRecipientFoundEventArgs e);

public class ArchivewriterRecipientFoundEventArgs : EventArgs {
  public byte[] PublicKeyHash { get; }
  public bool CertFound { get; }
}
Public Event OnRecipientFound As OnRecipientFoundHandler

Public Delegate Sub OnRecipientFoundHandler(sender As Object, e As ArchivewriterRecipientFoundEventArgs)

Public Class ArchivewriterRecipientFoundEventArgs Inherits EventArgs
  Public ReadOnly Property PublicKeyHash As Byte()
  Public ReadOnly Property CertFound As Boolean
End Class

Remarks

The component 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: component 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.

Config Settings (ArchiveWriter Component)

The component 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 component, access to these internal properties is provided through the Config method.

ArchiveWriter Config Settings

Attributes:   Provides means to pass platform file attributes for the files added to the archive.

Use this configuration setting to adjust attributes for the files that you add to the archive. Windows- and Unix-style attributes are supported: int idx1 = writer.AddVirtual("docs/document.doc"); int idx2 = writer.AddVirtual("build.sh"); writer.Config("Attributes[" + idx1.ToString() + "]=dos:readonly;hidden;archive;system"); writer.Config("Attributes[" + idx2.ToString() + "]=unix:-rwxr-xr-x");

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 component.

Supported values are:

offNo caching (default)
localLocal caching
globalGlobal caching

Cookies:   Gets or sets local cookies for the component.

Use this property to get cookies from the internal cookie storage of the component 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 components that have its CookieCaching property set to "global".

HttpUserAgent:   Specifies the user agent name to be used by all HTTP clients.

This global setting defines the User-Agent field of the HTTP request provides information about the software that initiates the request. This value will be used by all the HTTP clients including the ones used internally in other components.

LogDestination:   Specifies the debug log destination.

Contains a comma-separated list of values that specifies where debug log should be dumped.

Supported values are:

fileFile

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.

The default value of this setting is 100.

LogRotationMode:   Specifies the log rotation 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 component. 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 component) 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 component is set to "local", the property returns/restores the rules from/to the internal storage of the component. If StaticDNS of the component 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 components.

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.
