''

Remarks

The ID of the pre-shared key used for DC request authentication.

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";

Data Type

String

Parameter List

 'connectionid'
 'operationid'
 'hashalgorithm'
 'pars'
 'data'
 'signeddata'

Remarks

Assign a handler to this event if you need to delegate a low-level signing operation to an external, remote, or custom signing engine. Depending on the settings, the handler will receive a hashed or unhashed value to be signed.

The event handler must pass the value of Data to the signer, obtain the signature, and pass it back to the class via the SignedData parameter.

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

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

A sample MD5 hash encoded in base16: a0dee2a0382afbb09120ffa7ccd8a152 - lower case base16 A0DEE2A0382AFBB09120FFA7CCD8A152 - upper case base16

A sample event handler that uses the .NET RSACryptoServiceProvider class may look like the following: signer.OnExternalSign += (s, e) => { var cert = new X509Certificate2("cert.pfx", "", X509KeyStorageFlags.Exportable); var key = (RSACryptoServiceProvider)cert.PrivateKey; var dataToSign = e.Data.FromBase16String(); var signedData = key.SignHash(dataToSign, "2.16.840.1.101.3.4.2.1"); e.SignedData = signedData.ToBase16String(); };

secureblackbox_sftpserver_register_callback($res, 34, array($this, 'fireFindClose'));

Parameter List

 'connectionid'
 'handle'
 'operationstatus'

Remarks

FindClose notifies your code about the completion of a custom file listing request. Use it in conjunction with FindFirst and FindNext to handle file listing requests manually.

See FindFirst topic for the details on implementing customized file listing request processing.

Set OperationStatus to one of the below values according to the outcome of the request processing:

FindFirst Event (SecureBlackbox_SFTPServer Class)

This event signifies the start of the custom file listing retrieval mechanism.

Object Oriented Interface

public function fireFindFirst($param);

Procedural Interface

secureblackbox_sftpserver_register_callback($res, 35, array($this, 'fireFindFirst'));

Parameter List

 'connectionid'
 'path'
 'operationstatus'
 'handle'

Remarks

FindFirst, FindNext, and FindClose events represent a mechanism for providing customized file listings to class. They are only fired if Action parameter of the preceding BeforeFind event was set to fraCustom.

The behaviour of these events mimics that of the standard FindFirst/FindNext/FindClose functions found in many operating systems/frameworks. FindFirst fires once to request the first list entry; FindNext then fires continuously in a loop to request all subsequent entries. To indicate that the listing is over, set OperationStatus parameter to ostEOF. Not doing so may lead to an endless loop and session freeze, as the component would continue firing FindNext infinitely waiting for the EOF marker.

The handlers for both FindFirst and FindNext events should be implemented in the following way: if there are more entries in the directory to pass back to the server component,

• set OperationStatus to ostOK,
• fill in ClientFileEntry with the details of the next entry,
• commit the entry to the server using SetClientFileEntry method.

When all the entries from the requested directory have been passed to the server component, set OperationStatus to ostEOF. The server will then fire FindClose event to notify your code that the file listing is completed.

Use the by-ref Handle parameter to assign a handle (a unique identifier) to the file listing procedure inside the FindFirst event handler. This identifier will then be passed to all subsequent FindNext and FindClose calls to let your code chain the events together.

The ConnectionID parameter specifies in which SFTP session the request was received, and Path indicates the requested directory.

The following operation status constants are available, besides the ones referenced above:

FindNext Event (SecureBlackbox_SFTPServer Class)

This event retrieves the next entry of a custom file listing.

Object Oriented Interface

public function fireFindNext($param);

Procedural Interface

secureblackbox_sftpserver_register_callback($res, 36, array($this, 'fireFindNext'));

Parameter List

 'connectionid'
 'handle'
 'operationstatus'

Remarks

This event is fired repeatedly after FindFirst to retrieve the directory contents entry-by-entry. Please see the FindFirst topic for more details about implementing a handler of this event.

Remember to set OperationStatus to ostEOF when there are no more entries left to close the listing operation. If there are more entries to pass, set it to ostOK. Other possible values are given in the table below:

 'handle'

Remarks

This event is fired when a file open request is received from the client and needs to be handled (virtualized) by the server. The ConnectionID parameter specifies in which session the request was received, and Path specifies the location of the file.

Modes can be a combination of one or several file open mode flags:

Different client applications may provide different selections of mode flags. For example, some clients specify (cfmCreate + cfmTruncate) when overwriting files, whereas others would specify cfmOpenOrCreate. Please make sure your code is prepared to receive different combinations of flags here and handles them gracefully.

The Access parameter provides additional file access modifiers:

These parameter may also contain a combination of the above flags. Access modifiers are only supported in SFTPv6, and in practice are rarely used by client applications.

The Handle string represents a unique identifier of the opened file, similar to file handles used in Windows or Unix APIs. Handles are unique across all files opened at the same time. Class generates handles automatically, but you can update the auto-generated values with your own in this event handler (just remember to keep them unique).
