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

Syntax

nsoftware.SecureBlackbox.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

Work with ArchiveReader builds on the following steps:

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.

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 component 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.

ArchivedFile Type

Provides information about the compressed file.

Remarks

Use this type to access compressed file details.

The following fields are available:

Fields

Action
Actions

Default: 0

The action to apply to the file.

Use this property to control the action that should be applied to the file during the compression or extraction. The following actions are supported:

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)

Attributes
string

Default: ""

Provides access to file attributes.

ZIP archives support provision of Windows (or DOS, as they are called historically) or Unix file attributes. Use this property to provide the attributes or read them out of an existing archive.

Use "dos:" or "unix:" prefixes to indicate what kind of attributes you need to include:

Writer.Files[0].Attributes = "unix:-rwxr-xr-x"; Writer.Files[1].Attributes = "unix:-r--r--r--"; Writer.Files[2].Attributes = "dos:readonly"; Writer.Files[3].Attributes = "dos:readonly;hidden"; // supported values: readonly, hidden, system, volumeLabel, directory, archive

CompressedSize
long (read-only)

Default: 0

The size of the file after compression.

DataSource
FileDataSources

Default: 0

The type of the data source for this entry.

Use this property to control the data source for this entry.

fdsFile (0)The data for this entry should be taken from the file provided via LocalPath.
fdsStream (1)The data is going to be provided on-the-fly via the FileStream property.
fdsBuffer (2)The data is going to be provided on-the-fly via the FileData property.

Directory
bool (read-only)

Default: False

Tells if the entry is a directory or a regular file.

EncryptionAlgorithm
string (read-only)

Default: ""

Returns the symmetric algorithm that was used to encrypt the file.

EncryptionKeyLength
int (read-only)

Default: 0

Returns the length, in bits, of the encryption key.

EncryptionType
EncryptionTypes (read-only)

Default: 0

The type of encryption applied to the file.

Use this property to find out what kind of encryption was applied to the file.

aetDefault (0)Default encryption (not used for already encrypted files)
aetNoEncryption (1)No encryption
aetGeneric (2)Standard ZIP encryption
aetWinZip (3)WinZIP-based encryption
aetStrong (4)Strong encryption

FileName
string

Default: ""

The original name of the compressed file or folder.

Folder
string (read-only)

Default: ""

The containing folder of the entry.

LocalPath
string

Default: ""

The local path associated with this entry. It typically specifies the source path that the data should be taken from, or the destination it should be extracted to.

MTime
string

Default: ""

The entry's last modification time.

NewFile
bool (read-only)

Default: False

Indicates whether the entry corresponds to a file to be added to the archive.

Path
string (read-only)

Default: ""

The full internal path of the archived entry.

SignatureCount
int (read-only)

Default: 0

The number of signatures covering the entry.

Signed
bool (read-only)

Default: False

Indicates whether the entry is signed.

Size
long (read-only)

Default: 0

The size of the file before compression.

Constructors

public ArchivedFile();
Public ArchivedFile()

Creates a new ArchivedFile object.

Certificate Type

Encapsulates an individual X.509 certificate.

Remarks

This type keeps and provides access to X.509 certificate details.

The following fields are available:

Fields

Bytes
byte[] (read-only)

Default: ""

Returns the raw certificate data in DER format.

CA
bool

Default: False

Indicates whether the certificate has a CA capability. For the certificate to be considered a CA, it must have its Basic Constraints extension set with the CA indicator enabled.

Set this field when generating a new certificate to have its Basic Constraints extension generated automatically.

CAKeyID
byte[] (read-only)

Default: ""

A unique identifier (fingerprint) of the CA certificate's cryptographic key.

Authority Key Identifier is a certificate extension which allows identification of certificates belonging to the same issuer, but with different public keys. It is a de-facto standard to include this extension in all certificates to facilitate chain building.

This setting cannot be set when generating a certificate as it always derives from another certificate property. CertificateManager generates this setting automatically if enough information is available to it: for self-signed certificates, this value is copied from the SubjectKeyID setting, and for lower-level certificates, from the parent certificate's subject key ID extension.

CertType
CertTypes (read-only)

Default: 0

Returns the type of the entity contained in the Certificate object.

A Certificate object can contain two types of cryptographic objects: a ready-to-use X.509 certificate, or a certificate request ("an unsigned certificate"). Certificate requests can be upgraded to full certificates by signing them with a CA certificate.

Use the CertificateManager component to load or create new certificate and certificate requests objects.

CRLDistributionPoints
string

Default: ""

Contains a list of locations of CRL distribution points used to check this certificate's validity. The list is taken from the respective certificate extension.

Use this field when generating a certificate to provide a list of CRL endpoints that should be made part of the new certificate.

The endpoints are provided as a list of CRLF-separated URLs. Note that this differs from the behaviour used in earlier product versions, where the "|" character was used as the location separator.

Curve
string

Default: ""

Specifies the elliptic curve associated with the certificate's public key. This setting only applies to certificates containing EC keys.

Fingerprint
string (read-only)

Default: ""

Contains the fingerprint (a hash imprint) of this certificate.

While there is no formal standard defining what a fingerprint is, a SHA1 hash of the certificate's DER-encoded body is typically used.

FriendlyName
string (read-only)

Default: ""

Contains an associated alias (friendly name) of the certificate. The friendly name is not a property of a certificate: it is maintained by the certificate media rather than being included in its DER representation. Windows certificate stores are one example of media that does support friendly names.

HashAlgorithm
string

Default: ""

Provides means to set the hash algorithm to be used in the subsequent operation on the certificate (such as generation or key signing). It is not a property of a certificate; use SigAlgorithm to find out the hash algorithm that is part of the certificate signature.

Use the KeyBits, Curve, and PublicKeyBytes fields to get more details about the key the certificate contains.

KeyBits
int (read-only)

Default: 0

Returns the length of the public key in bits.

This value indicates the length of the principal cryptographic parameter of the key, such as the length of the RSA modulus or ECDSA field. The key data returned by the PublicKeyBytes or PrivateKeyBytes field would typically contain auxiliary values, and therefore be longer.

KeyFingerprint
string (read-only)

Default: ""

Returns a SHA1 fingerprint of the public key contained in the certificate.

Note that the key fingerprint is different from the certificate fingerprint accessible via the Fingerprint field. The key fingeprint uniquely identifies the public key, and so can be the same for multiple certificates containing the same key.

KeyUsage
int

Default: 0

Indicates the purposes of the key contained in the certificate, in the form of an OR'ed flag set.

This value is a bit mask of the following values:

ckuUnknown0x00000Unknown key usage

ckuDigitalSignature0x00001Digital signature

ckuNonRepudiation0x00002Non-repudiation

ckuKeyEncipherment0x00004Key encipherment

ckuCodeSigning0x00800Code signing

ckuEmailProtection0x01000Email protection

ckuTimeStamping0x02000Timestamping

ckuSmartCardLogon0x08000Smartcard logon

ckuKeyPurposeClientAuth0x10000Kerberos - client authentication

ckuKeyPurposeKDC0x20000Kerberos - KDC

Set this field before generating the certificate to propagate the key usage flags to the new certificate.

KeyValid
bool (read-only)

Default: False

Returns True if the certificate's key is cryptographically valid, and False otherwise.

OCSPLocations
string

Default: ""

Locations of OCSP services that can be used to check this certificate's validity in real time, as recorded by the CA.

Set this field before calling the certificate manager's Generate method to propagate it to the new certificate.

The OCSP locations are provided as a list of CRLF-separated URLs. Note that this differs from the behaviour used in earlier product versions, where the "|" character was used as the location separator.

OCSPNoCheck
bool

Default: False

Accessor to the value of the certificate's ocsp-no-check extension.

Origin
int (read-only)

Default: 0

Returns the location that the certificate was taken or loaded from.

PolicyIDs
string

Default: ""

Contains identifiers (OIDs) of the applicable certificate policies.

The Certificate Policies extension identifies a sequence of policies under which the certificate has been issued, and which regulate its usage.

Set this field when generating a certificate to propagate the policies information to the new certificate.

The policies are provided as a list of CRLF-separated entries. Note that this differs from the behaviour used in earlier product versions, where the "|" character was used as the policy element separator.

PrivateKeyBytes
byte[] (read-only)

Default: ""

Returns the certificate's private key in DER-encoded format. It is normal for this field to be empty if the private key is non-exportable, which, for example, is typical for certificates originating from hardware security devices.

PrivateKeyExists
bool (read-only)

Default: False

Indicates whether the certificate has a usable private key associated with it. If it is set to True, the certificate can be used for private key operations, such as signing or decryption.

This field is independent from PrivateKeyBytes, and can be set to True even if the former is empty. This would imply that the private key is non-exportable, but still can be used for cryptographic operations.

PrivateKeyExtractable
bool (read-only)

Default: False

Indicates whether the private key is extractable (exportable).

PublicKeyBytes
byte[] (read-only)

Default: ""

Contains the certificate's public key in DER format.

This typically would contain an ASN.1-encoded public key value. The exact format depends on the type of the public key contained in the certificate.

Qualified
bool (read-only)

Default: False

Indicates whether the certificate is qualified.

This property is set to True if the certificate is confirmed by a Trusted List to be qualified.

QualifiedStatements
QualifiedStatementsTypes

Default: 0

Returns a simplified qualified status of the certificate.

Qualifiers
string (read-only)

Default: ""

A list of qualifiers.

Contains a comma-separated list of qualifier aliases for the certificate, for example QCP-n-qscd,QCWithSSCD.

SelfSigned
bool (read-only)

Default: False

Indicates whether the certificate is self-signed (root) or signed by an external CA.

SerialNumber
byte[]

Default: ""

Returns the certificate's serial number.

The serial number is a binary string that uniquely identifies a certificate among others issued by the same CA. According to the X.509 standard, the (issuer, serial number) pair should be globally unique to facilitate chain building.

SigAlgorithm
string (read-only)

Default: ""

Indicates the algorithm that was used by the CA to sign this certificate.

A signature algorithm typically combines hash and public key algorithms together, such as sha256WithRSAEncryption or ecdsa-with-SHA256.

Source
PKISources (read-only)

Default: 0

Returns the source (location or disposition) of a cryptographic primitive entity, such as a certificate, CRL, or OCSP response.

Subject
string (read-only)

Default: ""

The common name of the certificate holder, typically an individual's name, a URL, an e-mail address, or a company name. This is part of a larger set of credentials available via SubjectRDN.

SubjectAlternativeName
string

Default: ""

Returns or sets the value of the Subject Alternative Name extension of the certificate.

Subject alternative names are used to provide additional names that are impractical to store in the main SubjectRDN field. For example, it is often used to store all the domain names that a TLS certificate is authorized to protect.

The alternative names are provided as a list of CRLF-separated entries. Note that this differs from the behaviour used in earlier product versions, where the "|" character was used as the element separator.

SubjectKeyID
byte[]

Default: ""

Contains a unique identifier of the certificate's cryptographic key.

Subject Key Identifier is a certificate extension which allows a specific public key to be associated with a certificate holder. Typically, subject key identifiers of CA certificates are recorded as respective CA key identifiers in the subordinate certificates that they issue, which facilitates chain building.

The SubjectKeyID and CAKeyID fields of self-signed certificates typically contain identical values, as in that specific case, the issuer and the subject are the same entity.

SubjectRDN
string

Default: ""

A list of Property=Value pairs that uniquely identify the certificate holder (subject).

Depending on the purpose of the certificate and the policies of the CA that issued it, the values included in the subject record may differ drastically and contain business or personal names, web URLs, email addresses, and other data.

Example: /C=US/O=Oranges and Apples, Inc./OU=Accounts Receivable/1.2.3.4.5=Value with unknown OID/CN=Margaret Watkins.

Valid
bool (read-only)

Default: False

Indicates whether or not the signature over the certificate or the request is valid and matches the public key contained in the CA certificate/request.

ValidFrom
string

Default: ""

The time point at which the certificate becomes valid, in UTC.

ValidTo
string

Default: ""

The time point at which the certificate expires, in UTC.

Config Settings (ArchiveReader 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.

ArchiveReader Config Settings

FilenamesCharset:   The character set to apply to archived file names.

Use this setting to apply a specific charset to the names of the archived files:

writer.Config("FilenamesCharset=cp852");

RestoreAttributes:   Specifies whether file and directory attributes should be restored upon extraction.

Set this property to true to tell ArchiveReader to restore file attributes when extracting files from the archive.

TempPath:   Path for storing temporary files.

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

Base Config Settings

ASN1UseGlobalTagCache:   Controls whether ASN.1 module should use a global object cache.

This is a performance setting. It is unlikely that you will ever need to adjust it.

AssignSystemSmartCardPins:   Specifies whether CSP-level PINs should be assigned to CNG keys.

This is a low-level tweak for certain cryptographic providers. It is unlikely that you will ever need to adjust it.

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.

DNSLocalSuffix:   The suffix to assign for TLD names.

Use this global setting to adjust the default suffix to assign to top-level domain names. The default is .local.

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".

HardwareCryptoUsePolicy:   The hardware crypto usage policy.

This global setting controls the hardware cryptography usage policy: auto, enable, or disable.

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.

HttpVersion:   The HTTP version to use in any inner HTTP client components created.

Set this property to 1.0 or 1.1 to indicate the HTTP version that any internal HTTP clients should use.

IgnoreExpiredMSCTLSigningCert:   Whether to tolerate the expired Windows Update signing certificate.

It is not uncommon for Microsoft Windows Update Certificate Trust List to be signed with an expired Microsoft certificate. Setting this global property to true makes SBB ignore the expired factor and take the Trust List into account.

ListDelimiter:   The delimiter character for multi-element lists.

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:

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.

OldClientSideRSAFallback:   Specifies whether the SSH client should use a SHA1 fallback.

Tells the SSH client to use a legacy ssh-rsa authentication even if the server indicates support for newer algorithms, such as rsa-sha-256. This is a backward-compatibility tweak.

ProductVersion:   Returns the version of the SecureBlackbox library.

This property returns the long version string of the SecureBlackbox library being used (major.minor.build.revision).

ServerSSLDHKeyLength:   Sets the size of the TLS DHE key exchange group.

Use this property to adjust the length, in bits, of the DHE prime to be used by the TLS server.

StaticDNS:   Specifies whether static DNS rules should be used.

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).

UseInternalRandom:   Switches between SecureBlackbox-own and platform PRNGs.

Allows to switch between internal/native PRNG implementation and the one provided by the platform.

UseLegacyAdESValidation:   Enables legacy AdES validation mode.

Use this setting to switch the AdES component to the validation approach that was used in SBB 2020/SBB 2022 (less attention to temporal details).

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.

UseSystemNativeSizeCalculation:   An internal CryptoAPI access tweak.

This is an internal setting. Please do not use it unless instructed by the support team.

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.
