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";

Object Oriented Interface

public function doConfig($configurationstring);

Procedural Interface

secureblackbox_xmldecryptor_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.

public function fireDecryptionInfoNeeded($param);

Procedural Interface

secureblackbox_xmldecryptor_register_callback($res, 1, array($this, 'fireDecryptionInfoNeeded'));

Parameter List

 'canceldecryption'

Remarks

This event is fired when the component needs decryption information (the private key) from the user.

Use EncryptKey, Config["KeyName"] and KeyEncryptionType properties to identify the encryption type and then set DecryptionKey or KeyDecryptionKey or KeyDecryptionCertificate properties accordingly.

if CancelDecryption property is set to true value (default value) then decryption would fail if provided key/certificate is invalid. Otherwise this event would be fired again.

Error Event (SecureBlackbox_XMLDecryptor Class)

Information about errors during signing.

Object Oriented Interface

public function fireError($param);

Procedural Interface

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

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

ExternalDecrypt Event (SecureBlackbox_XMLDecryptor Class)

Handles remote or external decryption.

Object Oriented Interface

public function fireExternalDecrypt($param);

Procedural Interface

secureblackbox_xmldecryptor_register_callback($res, 3, array($this, 'fireExternalDecrypt'));

Parameter List

 'operationid'
 'algorithm'
 'pars'
 'encrypteddata'
 'data'

Remarks

Assign a handler to this event if you need to delegate a low-level decryption operation to an external, remote, or custom decryption engine. The handler receives an encrypted value in the EncryptedData parameter, and is expected to decrypt it and place the decrypted value into the Data parameter.

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

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

Sample data encoded in base16: a0dee2a0382afbb09120ffa7ccd8a152 - lower case base16 A0DEE2A0382AFBB09120FFA7CCD8A152 - upper case base16

Parameter List

 'eventid'
 'eventparam'

Remarks

The class fires this event to let the application know about some event, occurrence, or milestone in the class. For example, it may fire to report completion of the document processing. The list of events being reported is not fixed, and may be flexibly extended over time.

The unique identifier of the event is provided in the EventID parameter. EventParam contains any parameters accompanying the occurrence. Depending on the type of the class, the exact action it is performing, or the document being processed, one or both may be omitted.

SaveExternalData Event (SecureBlackbox_XMLDecryptor Class)

Request to save decrypted external data.

Object Oriented Interface

public function fireSaveExternalData($param);

Procedural Interface

secureblackbox_xmldecryptor_register_callback($res, 5, array($this, 'fireSaveExternalData'));

Parameter List

 'externaldata'

Remarks

This event is fired when the component successfully decrypted an external data and needs to save it. The same data could be read using ExternalData property.

It makes sense to use this event when the XML document contains several xenc:EncryptedData elements and the component decrypts them all.

Config Settings (XMLDecryptor 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.
