Remarks

CryptoKeyManager allows you to load, save, generate, import, and export low-level crypto keys. One example of such keys are raw RSA keys stored in PKCS1 format or AES256 keys. CryptoKeyManager supports asymmetric, symmetric, and HMAC keys.

CryptoKeyManager is a typical companion for low-level cryptography classes, such as PublicKeyCrypto, SymmetricCrypto, and HashFunction. It can also be used to provide external key material to certificate objects, and to derive cryptographic keys from passwords.

Use ImportBytes or ImportFromFile method to load the key material from a buffer or file. Use ImportFromCert (and remember to assign the certificate object to the Certificate property before calling it) to import a key from an X.509 certificate. Once loaded, the key will be available in the Key property.

To generate a new key or keypair use Generate method. You can export the generated key using ExportBytes or ExportToFile method. You can attach the generated or loaded key to an external certificate object using the ExportToCert method.

Note: CryptoKeyManager can only work with one cryptographic key at a time. Use CryptoKeyStorage to access media containing more than one key.

This property is read-only and not available at design time.

Data Type

Boolean

KeyPublic Property (SecureBlackbox_CryptoKeyManager Class)

Returns True if the object hosts a public key, and False otherwise.

Object Oriented Interface

public function getKeyPublic();

Procedural Interface

secureblackbox_cryptokeymanager_get($res, 49 );

Default Value

false

Remarks

Returns True if the object hosts a public key, and False otherwise.

This property is read-only and not available at design time.

Data Type

Boolean

KeySubject Property (SecureBlackbox_CryptoKeyManager Class)

Returns the key subject.

Object Oriented Interface

public function getKeySubject();


public function setKeySubject($value);

Procedural Interface

secureblackbox_cryptokeymanager_get($res, 50 );


secureblackbox_cryptokeymanager_set($res, 50, $value );

Remarks

Returns the key subject. This is a cryptoprovider-dependent value, which normally aims to provide some user-friendly insight into the key owner.

This property is not available at design time.

Data Type

Byte Array

KeySymmetric Property (SecureBlackbox_CryptoKeyManager Class)

Returns True if the object contains a symmetric key, and False otherwise.

Object Oriented Interface

public function getKeySymmetric();

Procedural Interface

secureblackbox_cryptokeymanager_get($res, 51 );

Default Value

false

Remarks

Returns True if the object contains a symmetric key, and False otherwise.

This property is read-only and not available at design time.

Data Type

Boolean

KeyValid Property (SecureBlackbox_CryptoKeyManager Class)

Returns True if this key is valid.

Object Oriented Interface

public function getKeyValid();

Procedural Interface

secureblackbox_cryptokeymanager_get($res, 52 );

Default Value

false

Remarks

Returns True if this key is valid. The term Valid highly depends on the kind of the key being stored. A symmetric key is considered valid if its length fits the algorithm being set. The validity of an RSA key also ensures that the RSA key elements (primes, exponents, and modulus) are consistent.

This property is read-only and not available at design time.

Data Type

Boolean

Config Method (SecureBlackbox_CryptoKeyManager Class)

Sets or retrieves a configuration setting.

Object Oriented Interface

public function doConfig($configurationstring);

Procedural Interface

secureblackbox_cryptokeymanager_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.
