- (void)onExternalSign:(long long)connectionID :(NSString*)operationId :(NSString*)hashAlgorithm :(NSString*)pars :(NSString*)data :(NSString**)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(); };

FindClose Event (SFTPServer Module)

- (void)onFindClose:(long long)connectionID :(NSString*)handle :(int*)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 (SFTPServer Module)

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

Syntax

• Swift
• Objective-C

func onFindFirst(connectionID: Int64, path: String, operationStatus: inout Int32, handle: inout String)

- (void)onFindFirst:(long long)connectionID :(NSString*)path :(int*)operationStatus :(NSString**)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.

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 (SFTPServer Module)

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

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:

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.

This class can fire this event with the following EventID values:

OpenClientForwarding Event (SFTPServer Module)

This event is fired when a client opens a client-side (local) forwarding channel.

Syntax

• Swift
• Objective-C

func onOpenClientForwarding(connectionID: Int64, destHost: String, destPort: Int32, srcHost: String, srcPort: Int32)

- (void)onOpenClientForwarding:(long long)connectionID :(NSString*)destHost :(int)destPort :(NSString*)srcHost :(int)srcPort;

Remarks

This event notifies the application that a client-side forwarding channel has been set up. The ConnectionID parameter specifies in which session the request was received.

The DestHost and DestPort parameters specify the address that the data received from the client will be forwarded to. The SrcHost and SrcPort specify the connection origin that is reported by the client. Note that the details of the origin cannot be verified.

OpenCommand Event (SFTPServer Module)

This event is fired when a client has opened an SSH command channel.

Syntax

• Swift
• Objective-C

func onOpenCommand(connectionID: Int64, command: String)

- (void)onOpenCommand:(long long)connectionID :(NSString*)command;

Remarks

The ConnectionID parameter specifies in which session the request was received.

OpenFile Event (SFTPServer Module)

This event instructs the application to handle the file open request.

Syntax

• Swift
• Objective-C

func onOpenFile(connectionID: Int64, path: String, modes: Int32, access: Int32, operationStatus: inout Int32, handle: inout String)

- (void)onOpenFile:(long long)connectionID :(NSString*)path :(int)modes :(int)access :(int*)operationStatus :(NSString**)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:

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).

Set OperationStatus parameter in accordance with the outcome of the operation to one of the values given below:
