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 EncryptionCertificateSubjectKeyID setting, and for lower-level certificates, from the parent certificate's subject key ID extension.

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

Procedural Interface

secureblackbox_pdfencryptor_get($res, 13 );

Default Value

''

Remarks

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.

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

Data Type

String

EncryptionCertificateHandle Property (SecureBlackbox_PDFEncryptor Class)

Allows to get or set a 'handle', a unique identifier of the underlying property object.

Config Method (SecureBlackbox_PDFEncryptor Class)

Sets or retrieves a configuration setting.

Object Oriented Interface

public function doConfig($configurationstring);

Procedural Interface

secureblackbox_pdfencryptor_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_PDFEncryptor Class)

Performs an additional action.

Object Oriented Interface

public function doDoAction($actionid, $actionparams);

Procedural Interface

secureblackbox_pdfencryptor_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;....

Encrypt Method (SecureBlackbox_PDFEncryptor Class)

Object Oriented Interface

public function fireDocumentLoaded($param);

Procedural Interface

secureblackbox_pdfencryptor_register_callback($res, 1, array($this, 'fireDocumentLoaded'));

Parameter List

 'cancel'

Remarks

The handler for this event is a good place to check the document structure, which may be useful when preparing the signature. For example, you can use the Pages information to find the optimal position for the signature widget.

Set Cancel to true to terminate document processing on this stage.

Error Event (SecureBlackbox_PDFEncryptor Class)

Information about errors during encryption.

Object Oriented Interface

public function fireError($param);

Procedural Interface

secureblackbox_pdfencryptor_register_callback($res, 2, array($this, 'fireError'));
