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

ExternalDecrypt Event (SecureBlackbox_PGPReader Class)

Handles remote or external decryption.

Object Oriented Interface

public function fireExternalDecrypt($param);

Procedural Interface

secureblackbox_pgpreader_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

 'filename'
 'timestamp'
 'skip'

Remarks

This event informs about the beginning of extraction of the next available file. A PGP message may contain more than one file. FileName parameter indicates the original file name, and the Timestamp its last modification time.

The user should provide an output filename in OutputFile or a stream in OutputStream. If none of them is provided, the extracted file will be placed to OutputBytes. After the file is extracted, FileExtractionFinish event is fired.

KeyPassphraseNeeded Event (SecureBlackbox_PGPReader Class)

Requests a key protection password from the application.

Object Oriented Interface

public function fireKeyPassphraseNeeded($param);

Procedural Interface

secureblackbox_pgpreader_register_callback($res, 6, array($this, 'fireKeyPassphraseNeeded'));

Parameter List

 'keyid'
 'userid'
 'mainkey'
 'passphrase'
 'skip'

Remarks

The class fires this event to request a secret key passphrase from the application. Note that this event asks for a key protection passphrase rather than a message protection passphrase (which is requested via PassphraseNeeded). The class fires it when it has found a suitable decryption secret key in the keyring, and attempts to use it to decrypt the data.

If the data is encrypted with multiple keys, this event is called for each key in a loop until the password for at least one key is provided correctly. KeyID specifies the key for which the password is requested, and UserID identifies its user. MainKey tells whether the key is a master key or a subkey.

The handler should provide password via the Passphrase parameter, or set Skip to True to skip this key.

For each key KeyPassphraseNeeded is called in a loop until the correct password is provided or the maximum number of password attempts reached.
