ArchiveReader Component
Properties Methods Events Config Settings Errors
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.

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.
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:
ckuUnknown | 0x00000 | Unknown key usage |
ckuDigitalSignature | 0x00001 | Digital signature |
ckuNonRepudiation | 0x00002 | Non-repudiation |
ckuKeyEncipherment | 0x00004 | Key encipherment |
ckuDataEncipherment | 0x00008 | Data encipherment |
ckuKeyAgreement | 0x00010 | Key agreement |
ckuKeyCertSign | 0x00020 | Certificate signing |
ckuCRLSign | 0x00040 | Revocation signing |
ckuEncipherOnly | 0x00080 | Encipher only |
ckuDecipherOnly | 0x00100 | Decipher only |
ckuServerAuthentication | 0x00200 | Server authentication |
ckuClientAuthentication | 0x00400 | Client authentication |
ckuCodeSigning | 0x00800 | Code signing |
ckuEmailProtection | 0x01000 | Email protection |
ckuTimeStamping | 0x02000 | Timestamping |
ckuOCSPSigning | 0x04000 | OCSP signing |
ckuSmartCardLogon | 0x08000 | Smartcard logon |
ckuKeyPurposeClientAuth | 0x10000 | Kerberos - client authentication |
ckuKeyPurposeKDC | 0x20000 | Kerberos - 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.
