ExternalCryptoKeyID Property (SecureBlackbox_PGPWriter Class)

The ID of the pre-shared key used for DC request authentication.

Object Oriented Interface


public function getExternalCryptoKeyID();


public function setExternalCryptoKeyID($value);

Procedural Interface


secureblackbox_pgpwriter_get($res, 44 );


secureblackbox_pgpwriter_set($res, 44, $value );

Default Value

''

Remarks

The ID of the pre-shared key used for DC request authentication.

Asynchronous DCAuth-driven communication requires that parties authenticate each other with a secret pre-shared cryptographic key. This provides an extra protection layer for the protocol and diminishes the risk of the private key becoming abused by foreign parties. Use this property to provide the pre-shared key identifier, and use ExternalCryptoKeySecret to pass the key itself.

The same KeyID/KeySecret pair should be used on the DCAuth side for the signing requests to be accepted.

Note: The KeyID/KeySecret scheme is very similar to the AuthKey scheme used in various Cloud service providers to authenticate users.

Example: signer.ExternalCrypto.KeyID = "MainSigningKey"; signer.ExternalCrypto.KeySecret = "abcdef0123456789";

Data Type

String

Error Event (SecureBlackbox_PGPWriter Class)

Information about errors during PGP encryption.

Object Oriented Interface

public function fireError($param);

Procedural Interface

secureblackbox_pgpwriter_register_callback($res, 1, array($this, 'fireError'));

Parameter List

 'errorcode'
'description'

Remarks

The event is fired in case of exceptional conditions during data encryption or signing.

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

ExternalSign Event (SecureBlackbox_PGPWriter Class)

Handles remote or external signing initiated by the SignExternal method or other source.

Object Oriented Interface

public function fireExternalSign($param);

Procedural Interface

secureblackbox_pgpwriter_register_callback($res, 2, array($this, 'fireExternalSign'));

Parameter List

 'operationid'
'hashalgorithm'
'pars'
'data'
'signeddata'

Remarks

Assign a handler to this event if you need to delegate a low-level signing operation to an external, remote, or custom signing engine. Depending on the settings, the handler will receive a hashed or unhashed value to be signed.

The event handler must pass the value of Data to the signer, obtain the signature, and pass it back to the class via the SignedData parameter.

OperationId provides a comment about the operation and its origin. It depends on the exact class being used, and may be empty. HashAlgorithm specifies the hash algorithm being used for the operation, and Pars contains algorithm-dependent parameters.

The class uses base16 (hex) encoding for the Data, SignedData, and Pars parameters. If your signing engine uses a different input and output encoding, you may need to decode and/or encode the data before and/or after the signing.

A sample MD5 hash encoded in base16: a0dee2a0382afbb09120ffa7ccd8a152 - lower case base16 A0DEE2A0382AFBB09120FFA7CCD8A152 - upper case base16

A sample event handler that uses the .NET RSACryptoServiceProvider class may look like the following: signer.OnExternalSign += (s, e) => { var cert = new X509Certificate2("cert.pfx", "", X509KeyStorageFlags.Exportable); var key = (RSACryptoServiceProvider)cert.PrivateKey; var dataToSign = e.Data.FromBase16String(); var signedData = key.SignHash(dataToSign, "2.16.840.1.101.3.4.2.1"); e.SignedData = signedData.ToBase16String(); };

KeyPassphraseNeeded Event (SecureBlackbox_PGPWriter Class)

Requests a key protection password from the application.

Object Oriented Interface

public function fireKeyPassphraseNeeded($param);

Procedural Interface

secureblackbox_pgpwriter_register_callback($res, 3, array($this, 'fireKeyPassphraseNeeded'));

Parameter List

 'keyid'
'userid'
'mainkey'
'passphrase'
'skip'

Remarks

The class fires this event to request a secret key passphrase from the application. Note that this event asks for a key protection passphrase rather than a message protection passphrase. The class fires it when it attempts to use a secret key to sign the data.

This event is fired for every protected secret key residing in SigningKeys. KeyID specifies the key for which the password is requested, and UserID identifies its user. MainKey tells whether the key is a master key or a subkey.

The handler should provide password via the Passphrase parameter, or set Skip to True to skip this key.

For each key KeyPassphraseNeeded is called in a loop until the correct password is provided or the maximum number of password attempts reached.

Reports the progress of the decryption operation.

Object Oriented Interface

public function fireProgress($param);

Procedural Interface

secureblackbox_pgpwriter_register_callback($res, 5, array($this, 'fireProgress'));

Parameter List

 'current'
'total'
'cancel'

Remarks

The class fires this event repeatedly to report the progress of the file protection operation.

Current indicates the amount of processed data in bytes, and Total is the total number of bytes to be processed. Use Cancel to terminate the protection process.

Config Settings (PGPWriter 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.

PGPWriter Config Settings

PasswordAttempts:   The number of attempts allowed for entering password.

Use this property to specify how many times a wrong password may be entered.

PreserveFilePaths:   Whether to preserve full file names when saving the PGP file.

When this property is False, the Encrypt and Sign methods save only the file names (without full paths) to the PGP file.

When this property is True, the file names are saved exactly as they are passed to the above mentioned methods, including full paths. This lets you to save directory structures to the encrypted and/or signed PGP files.

SignBufferingMethod:   The type of buffering used during signing.

Specifies the behaviour of the signer when operating with the input stream. Allowed values are: 0 - create a temporary stream and copy all data into it; 1 - rewind the input stream. The last option is useful when you have a stream which doesn't support seek operation such as a network stream or a decompressor stream.

TempPath:   Path for storing temporary files.

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

TextCompatibilityMode:   Whether whitespaces must be trimmed from the signature.

Several versions of PGP have a bug in their implementations which results in creation of incorrect text signatures because they only remove trailing whitespaces from cleartext signatures. Technically, such signatures are not OpenPGP-compliant. Set this property to True if you want to interoperate with these implementations. Set this property to False if you need to create only OpenPGP-compliant messages.

UndefInputLength:   Set this property if you are working with non-seekable streams.

Use this property to turn on support for streams with unknown length and position parameters, such as network or database streams. It prevents the class from checking input stream length or position.

UseNewFeatures:   Whether the new algorithms, or only the algorithms compatible with PGP 2.6.x, are allowed.

Use this property for compatibility with old versions of PGP-compatible software. If this property is set to True, then newer and stronger algorithms will be used. In this case ClearTextSign and Sign will be compatible with PGP 2.6.x, while Encrypt and EncryptAndSign will not. If the property is set to False, then the result will be compatible with PGP 2.6.x, while the keys are compatible (i.e. don't use features not supported by PGP 2.6.x).

UseOldPackets:   Whether signature packets of old format, compatible with PGP 2.6.3, should be used.

The signature is fully compatible with the 'old' format only if it has version 3, uses MD5 hash algorithm, RSA public key algorithm, and its key length is not greater than 1024 bits.

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)
localLocal caching
globalGlobal caching

Cookies:   Gets or sets local cookies for the class.

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".

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 classes.

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
consoleConsole
systemlogSystem Log (supported for Android only)
debuggerDebugger (supported for VCL for Windows and .Net)

LogDetails:   Specifies the debug log details to dump.

Contains a comma-separated list of values that specifies which debug log details to dump.

Supported values are:

timeCurrent time
levelLevel
packagePackage name
moduleModule name
classClass name
methodMethod name
threadidThread Id
contenttypeContent type
contentContent
allAll details

LogFile:   Specifies the debug log filename.

Use this property to provide a path to the log file.

LogFilters:   Specifies the debug log filters.

Contains a comma-separated list of value pairs ("name:value") that describe filters.

Supported filter names are:

exclude-packageExclude a package specified in the value
exclude-moduleExclude a module specified in the value
exclude-classExclude a class specified in the value
exclude-methodExclude a method specified in the value
include-packageInclude a package specified in the value
include-moduleInclude a module specified in the value
include-classInclude a class specified in the value
include-methodInclude a method specified in the value

LogFlushMode:   Specifies the log flush mode.

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

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 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.
