Config Method (SecureBlackbox_PGPKeyManager Class)

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 insensitive) 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);

Use this method to save the public key contained in Key to a byte array.

ExportPublicToFile Method (SecureBlackbox_PGPKeyManager Class)

Exports the public key to a file.

Object Oriented Interface

public function doExportPublicToFile($filename);

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: Supported elliptic curves:
