Sets or retrieves a configuration setting.

Object Oriented Interface

public function doConfig($configurationstring);

Procedural Interface

secureblackbox_pgpkeymanager_do_config($res, $configurationstring);

Remarks

Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These 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.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

DoAction Method (SecureBlackbox_PGPKeyManager Class)

Performs an additional action.

Object Oriented Interface

public function doDoAction($actionid, $actionparams);

Procedural Interface

secureblackbox_pgpkeymanager_do_doaction($res, $actionid, $actionparams);

Remarks

DoAction is a generic method available in every class. It is used to perform an additional action introduced after the product major release. The list of actions is not fixed, and may be flexibly extended over time.

The unique identifier (case insencitive) of the action is provided in the ActionID parameter.

ActionParams contains the value of a single parameter, or a list of multiple parameters for the action in the form of PARAM1=VALUE1;PARAM2=VALUE2;....

ExportKey Method (SecureBlackbox_PGPKeyManager Class)

Serializes the key to a byte array.

Object Oriented Interface

public function doExportKey();

Procedural Interface

secureblackbox_pgpkeymanager_do_exportkey($res);

Remarks

Use this method to save the Key (both the public and secret parts) to a byte array.

ExportPublicKey Method (SecureBlackbox_PGPKeyManager Class)

Exports the public key to a byte array.

Object Oriented Interface

public function doExportPublicKey();

Procedural Interface

secureblackbox_pgpkeymanager_do_exportpublickey($res);

Remarks

Object Oriented Interface

public function doExportPublicToFile($filename);

Procedural Interface

secureblackbox_pgpkeymanager_do_exportpublictofile($res, $filename);

Remarks

ExportToFile Method (SecureBlackbox_PGPKeyManager Class)

Exports the key to a file.

Object Oriented Interface

public function doExportToFile($filename);

Procedural Interface

secureblackbox_pgpkeymanager_do_exporttofile($res, $filename);

Remarks

Use this method to save the Key (both the public and secret parts) to the file specified in Filename.

Generate Method (SecureBlackbox_PGPKeyManager Class)

Generates a new single PGP key.

Object Oriented Interface

public function doGenerate();

Procedural Interface

secureblackbox_pgpkeymanager_do_generate($res);

Remarks

Call this method after setting up relevant fields of Key to generate a new PGP key. This method generates a 'standalone' key without subkeys. Use GeneratePair to generate a pair of a main key and a subkey.

Most PGP implementations work with pairs of keys: the sign-only primary key and the encrypt-only (or encrypt-and-sign) subkey. If you need to generate a conformant PGP key to use with other PGP software, you likely need to use the GeneratePair method.

GenerateLegacy Method (SecureBlackbox_PGPKeyManager Class)

Generates a new key in the old format.

Object Oriented Interface

public function doGenerateLegacy($username, $bits, $password, $expires);

Procedural Interface

secureblackbox_pgpkeymanager_do_generatelegacy($res, $username, $bits, $password, $expires);

Remarks

Use this method when you need to generate an RSA key in the old (PGP 2.6.x) format.

Username specifies the user of the key, Bits is the key length in bits. Provide Password for the key and its expiration date and time via Expires.

Only use this method where you want to work with very old PGP software. While still providing a decent level of protection (subject to key length, of course), legacy keys are rarely used these days, and have almost everywhere been replaced with new-style keys.

Most modern PGP implementations work with pairs of keys: the sign-only primary key and the encrypt-only (or encrypt-and-sign) subkey. If you need to generate a conformant PGP key to use with other PGP software, you likely need to use the GeneratePair method.

GeneratePair Method (SecureBlackbox_PGPKeyManager Class)

Generates a new pair of PGP keys.

Object Oriented Interface

public function doGeneratePair($username, $keyalgorithm, $keybits, $subkeyalgorithm, $subkeybits, $password, $expires);

Procedural Interface

secureblackbox_pgpkeymanager_do_generatepair($res, $username, $keyalgorithm, $keybits, $subkeyalgorithm, $subkeybits, $password, $expires);

Remarks

Use this method to create a new key-subkey pair. This is the primary method for generating conformant PGP keys.

Pass the user ID of the new key via the Username property. This typically should be in the format of User Name <user@email>, for example Robert Frost <robert@frost.com>, but generally can be an arbitrary text string.

Set KeyAlgorithm and SubKeyAlgorithm to the public key algorithms that you want to use for the new key. See the full list of algorithms below. Where ECDSA or ECDH algorithm is used, you can specify a particular curve after the algorithm name, separated with the colon: ECDSA:P384 or ECDH:BRAINPOOLP256. KeyBits and SubKeyBits specify the number of bits in the key and the subkey. These parameters can be set to zero if the key length is implicitly defined by the algorithm of the key. For example, ECDSA P256 keys are always 256 bit long, so you may pass 0 as the corresponding KeyBits or SubKeyBits parameter.

Provide the key encryption password and the validity period in days via the Password and Expires parameters. Set Expires to zero to indicate that the key does not expire.

While you can use any combination of algorithms for your key and subkey, most implementations got used to specific hard-wired combinations. Sticking to those will help make sure your keys are understood by other implementations. Typical combinations are:

  • EDDSA main key with ECDH:CURVE25519 subkey;
  • ECDSA main key with ECDH subkey; both with NIST curves (P256, P384, or P512);
  • ECDSA main key with ECDH subkey; both with Brainpool curves (BRAINPOOLP256 or BRAINPOOLP512);
  • RSA main key with RSA subkey.
The code snippet below illustrates a typical key generation procedure: Pgpkeymanager mgr = new Pgpkeymanager(); // generating a pair mgr.GeneratePair("Michel Legrand <ml@email.com>", "EDDSA", 0, "ECDH:CURVE25519", 0, "password", 0); // creating a keyring object and adding the new pair to the keyring Pgpkeyring keyring = new Pgpkeyring(); keyring.CreateNew(); keyring.PinnedKey = mgr.Key; keyring.AddPinned(); // exporting the keyring to a file keyring.Save("pubkey.pkr", "seckey.skr"); Alternative calls to GeneratePair may look like this: mgr.GeneratePair("Michel Legrand <ml@email.com>", "ECDSA:P384", 0, "ECDH", 0, "password", 0); mgr.GeneratePair("Michel Legrand <ml@email.com>", "ECDSA:BRAINPOOLP256", 0, "ECDH:BRAINPOOLP256", 0, "password", 0); mgr.GeneratePair("Michel Legrand <ml@email.com>", "RSA", 4096, "RSA", 2048, "password", 0); Supported public key algorithms:

Config Settings (PGPKeyManager 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.

PGPKeyManager Config Settings

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

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.
