Remarks

Use SSHClient to establish terminal-like connections to remote systems and run commands remotely. The component supports most of third-party implementations out there, and is capable of working in "shell" and "command" modes.

Start with assigning your sign-in credentials to Username and Password properties. Where public key authentication is to be used, assign your private authentication key to Key property (remember to set Username in this case too). Subscribe to events to be notified of the session progress. AuthFailed, AuthSucceeded, and Connect are among those particularly useful.

Special attention should be paid to setting up the server key trust. Class only allows connections to servers whose public keys are recognized as trusted, much like any other SSH clients do. Assign a path to the file containing the list of trusted keys to TrustedKeysFile property. If you don't have such file, or if you would like to make trust decisions on the fly, subscribe to KnownKeyReceived and UnknownKeyReceived events. These are fired whenever a trusted or untrusted key is received from the server. For unknown/untrusted keys, you need to set the Action parameter in your UnknownKeyReceived event handler to catAcceptOnce (1) or catAcceptPermanently (2) for the connection to proceed.

Once you are all set up, you can go ahead by calling the Connect method. This launches the SSH handshake and, if everything has been set up right, establishes a connection to the server. You can now use Send and Receive methods to exchange information with the server. You can exchange data in synchronous or asynchronous way; see the description in AsyncMode topic to learn more about each mode.

When you are done with the session, call Disconnect to shut the connection down.

Hint: If you are only interested in a quick-and-dirty execution of a simple, non-interactive command, SSHClient offers a handy shortcut. ConnectAndExec method is a self-contained mechanism which sets up a connection, performs the data exchange internally, and returns the command output. Please keep in mind that you still need to set up the server trust settings as described above for this method to work.

AsyncMode Property (SecureBlackbox_SSHClient Class)

Controls the SSH clients mode of work.

Object Oriented Interface

public function getAsyncMode();


public function setAsyncMode($value);

Procedural Interface

secureblackbox_sshclient_get($res, 1 );


secureblackbox_sshclient_set($res, 1, $value );

Default Value

false

Remarks

This property defines the way in which the class communicates with the application/user code. AsyncMode set to false makes the component use synchronous single-thread approach. Synchronous mode is generally simpler to integrate and use, but please keep in mind that the calls like Connect, Receive or SendBytes may block until their execution completes. In asyncronous mode all operations return immediately, but more care should be taken about handling them in your code properly.

Here are a few highlights of each mode.

Synchronous mode:

• All operations are performed within the caller thread context
• Operations like Connect or SendBytes may block
• Use Poll to check for the availability of data before reading it out with Receive or ReceiveBytes
• Return of a call guarantees completion of the operation
• Connection errors are reported straight from the methods via exceptions

Asynchronous mode:

• All operations are performed in a separate thread (and so are the event calls!)
• Methods like Send return immediately
• Use DataSent and DataReceived events to be notified about actual data transmissions
• Return of call only marks the beginning of the operation and does not guarantee its successful completion
• Connection errors are reported via Error event, often followed by Disconnect.

Please note that this is a very important and sensitive property, which has a wide-scale effect on the way the SSH client works and co-operates with the application. Depending on the value assigned to this setting you may need to work with the component very differently.

When setting this property to true, please make sure that your code is prepared to handle events coming from the context of a different thread.

''

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

ExternalCryptoKeySecret Property (SecureBlackbox_SSHClient Class)

Config Method (SecureBlackbox_SSHClient Class)

Sets or retrieves a configuration setting.

Object Oriented Interface

public function doConfig($configurationstring);

Procedural Interface

secureblackbox_sshclient_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.

Connect Method (SecureBlackbox_SSHClient Class)

Establishes connection to an SSH server.

Object Oriented Interface

public function doConnect($address, $port);

Procedural Interface

secureblackbox_sshclient_do_connect($res, $address, $port);

Remarks

Use this method to connect to the SSH server by providing its Address and Port.

Before connecting to the server you might want to set up your credentials using Username and Password properties. You might also need to configure the server key validation routine. You can do this by subscribing to KnownKeyReceived and UnknownKeyReceived events and implementing the event handlers as required.

Adjust AsyncMode before connecting to switch the component to either synchronous or asynchronous mode. In synchronous mode, all the calls to the component, such as Connect or SendBytes, are executed within the context of the caller thread, and block until the action completes. In asynchronous mode, the component runs the SSH session in a background thread, which makes all such calls return immediately. Find out more about the modes in the AsyncMode topic.

ConnectAndExec Method (SecureBlackbox_SSHClient Class)

Connects to an SSH server and executes a command in one go.

Object Oriented Interface

public function doConnectAndExec($address, $port, $command, $wantstdout, $wantstderr);

Procedural Interface

secureblackbox_sshclient_do_connectandexec($res, $address, $port, $command, $wantstdout, $wantstderr);

Remarks

Use this method to connect to an SSH server at Address and Port and execute a command. The method returns the output of the executed command.

This method is a handy shortcut for running non-interactive commands. It encapsulates calls to Connect, Receive, Disconnect internally to save you time and space.

Please note that ConnectAndExec always runs synchronously, thus ignoring the AsyncMode setting.

Disconnect Method (SecureBlackbox_SSHClient Class)

Closes connection to the SSH server.

Object Oriented Interface

public function doDisconnect();

Procedural Interface

secureblackbox_sshclient_do_disconnect($res);

Remarks

Call this method to terminate the active SSH connection.

Please note that in some cases the component may still have some inbound data cached internally even after the connection is closed. You can read that data out using Receive and/or ReceiveBytes methods.

DoAction Method (SecureBlackbox_SSHClient Class)

Performs an additional action.

Object Oriented Interface

public function doDoAction($actionid, $actionparams);

Procedural Interface

secureblackbox_sshclient_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;....

Ping Method (SecureBlackbox_SSHClient Class)

Sends a keep-alive request to the SSH server.

Object Oriented Interface

public function doPing();

Procedural Interface

secureblackbox_sshclient_do_ping($res);

Remarks

Use this method to send a keep-alive message to the SSH server. Keep-alive messages are empty data packets which carry no useful information but are a handy way of checking if the connection is still alive.

Poll Method (SecureBlackbox_SSHClient Class)

Checks whether there is any inbound data readily available.

Object Oriented Interface

public function doPoll($milliseconds);

Procedural Interface

secureblackbox_sshclient_do_poll($res, $milliseconds);

Remarks

Use this method to check whether there is any incoming data available in the connection. If this method returns true, you can read the data with Receive or ReceiveBytes calls.

Use the Milliseconds parameter to tell the component how long it can wait for the data to arrive.

Receive Method (SecureBlackbox_SSHClient Class)

Reads a portion of received data into a string.

Object Oriented Interface

public function doReceive();

Procedural Interface

secureblackbox_sshclient_do_receive($res);

Remarks

Use this method to read out a piece of data received from the server into a string.

Note that in synchronous mode this method may block in the absence of any inbound data until the next piece of data is received from the server. Use Poll to check if there is any data in the connection that is immediately available for reading.

In asynchronous mode a good time to call this method is upon receiving a read notification in DataReceived event handler. When working in asynchronous mode, this call returns immediately.

This method only returns data that arrives via the stdout channel. Use ReceiveFrom to read stderr data.

ReceiveBytes Method (SecureBlackbox_SSHClient Class)

Reads a portion of received data into a byte array.

Object Oriented Interface

public function doReceiveBytes($maxlen);

Procedural Interface

secureblackbox_sshclient_do_receivebytes($res, $maxlen);

Note that in synchronous mode this method may block in the absence of any inbound data until the next piece of data is received from the server. Use Poll to check if there is any data in the connection that is immediately available for reading.

In asynchronous mode a good time to call this method is upon receiving a read notification in DataReceived event handler. When working in asynchronous mode, this call returns immediately.

This method only returns data that arrives via the stdout channel. Use ReceiveBytesFrom to read stderr data.

ReceiveBytesFrom Method (SecureBlackbox_SSHClient Class)

Reads a portion of data received via a specific channel into a byte array.

Object Oriented Interface

public function doReceiveBytesFrom($channel, $maxlen);

Procedural Interface

secureblackbox_sshclient_do_receivebytesfrom($res, $channel, $maxlen);

Remarks

Use this method to read out a piece of data received from the server into a byte array. Specify the channel that you are interested in reading from (0 for stdout, 1 for stderr) via the Channel parameter, and control the maximum length of the data chunk with the MaxLen parameter.

Note that in synchronous mode this method may block in the absence of any inbound data until the next piece of data is received from the server. Use Poll to check if there is any data in the connection that is immediately available for reading.

In asynchronous mode a good time to call this method is upon receiving a read notification in DataReceived event handler. When working in asynchronous mode, this call returns immediately.

Please also note that stdout and stderr channels are fully independent, which implies that data arriving via each channel should be read out separately.

ReceiveFrom Method (SecureBlackbox_SSHClient Class)

Reads a portion of data received via a specific channel into a string.

Object Oriented Interface

public function doReceiveFrom($channel);

Procedural Interface

secureblackbox_sshclient_do_receivefrom($res, $channel);

Remarks

Use this method to read out a piece of data received from the server into a string. Use the Channel parameter to specify the channel that you would like to read from (0 for stdout, 1 for stderr).

Note that in synchronous mode this method may block in the absence of any inbound data until the next piece of data is received from the server. Use Poll to check if there is any data in the connection that is immediately available for reading.

In asynchronous mode a good time to call this method is upon receiving a read notification in DataReceived event handler. When working in asynchronous mode, this call returns immediately.

Object Oriented Interface

public function doSend($datastr, $addeol);

Procedural Interface

secureblackbox_sshclient_do_send($res, $datastr, $addeol);

Remarks

Use this method to send DataStr to the remote command's stdin channel. Set the AddEOL parameter to true to append the end-of-line character to the string automatically.

Note that in synchronous mode this method may block until the whole string is commited to the network connection. In asynchronous mode this method returns immediately; the application is eventually notified that the data has been sent via the DataSent event.

SendBytes Method (SecureBlackbox_SSHClient Class)

Sends an array of bytes to the server.

Object Oriented Interface

public function doSendBytes($data);

Procedural Interface

secureblackbox_sshclient_do_sendbytes($res, $data);

This event is fired for all commands in the Commands list, in order. The completion of the command is reported via the CommandCompleted event.

Connect Event (SecureBlackbox_SSHClient Class)

This event is fired when an SSH session has been established.

Object Oriented Interface

public function fireConnect($param);

Procedural Interface

secureblackbox_sshclient_register_callback($res, 7, array($this, 'fireConnect'));

Parameter List

Remarks

Use this event to track the moment when SSH session has been set up.

DataReceived Event (SecureBlackbox_SSHClient Class)

Reports receipt of another chunk of data from the server.

Object Oriented Interface

public function fireDataReceived($param);

Procedural Interface

secureblackbox_sshclient_register_callback($res, 8, array($this, 'fireDataReceived'));

Parameter List

 'channel'
 'bytesreceived'
 'totalbytespending'

Remarks

This event fires in asynchronous mode to report the receipt of another chunk of data from the server. Use Receive or ReceiveBytes methods to read out the received data.

The Channel parameter indicates the channel on which the data was received: stdout (0) or stderr (1). BytesReceived specify the size of the newly received chunk, and TotalBytesPending contain the total number of bytes available for reading.

Please note that just like other asynchronous mode events this event may fire from a secondary thread. Please make sure your code is prepared for that by using appropriate synchronization facilities.

This event does not fire in synchronous mode.

DataSent Event (SecureBlackbox_SSHClient Class)

Notifies the application that a piece of data has been sent to the server.

Object Oriented Interface

public function fireDataSent($param);

Procedural Interface

secureblackbox_sshclient_register_callback($res, 9, array($this, 'fireDataSent'));

Parameter List

 'bytessent'
 'bytespending'

Remarks

Subscribe to this event to be notified about the outbound data flow. This event fires following a call to Send or SendBytes methods to notify the application that the data provided has been sent to the server. This event may fire more than once for each Send or SendBytes call, subject to the volume of data being sent and the settings of the server.

The BytesSent parameter specifies the number of bytes that has just been sent to the server. The BytesPending indicate the number of bytes that remain cached in the internal buffer. Any bytes cached in such way will be sent again on the next available opportunity and reported via a separate DataSent event invocation.

Please note that just like other asynchronous mode events this event may fire from a secondary thread. Please make sure your code is prepared for that by using appropriate synchronization facilities.

This event does not fire in synchronous mode.

Disconnect Event (SecureBlackbox_SSHClient Class)

This event is fired when the SFTP subsystem connection is closed.

Object Oriented Interface

public function fireDisconnect($param);

Procedural Interface

secureblackbox_sshclient_register_callback($res, 10, array($this, 'fireDisconnect'));

Parameter List

 'closereason'

Remarks

Do not perform any file operations after this event has been fired.

Error Event (SecureBlackbox_SSHClient Class)

Information about errors during SFTP connection.

Object Oriented Interface

public function fireError($param);

Procedural Interface

secureblackbox_sshclient_register_callback($res, 11, array($this, 'fireError'));

Parameter List

 'errorcode'
 'description'

Remarks

The event is fired in case of exceptional conditions during data transfer.

ErrorCode contains an error code and Description contains a textual description of the error. For a list of error codes please refer to SFTP.

ExternalSign Event (SecureBlackbox_SSHClient Class)

Handles remote or external signing initiated by the SignExternal method or other source.

Object Oriented Interface

public function fireExternalSign($param);

Procedural Interface

secureblackbox_sshclient_register_callback($res, 12, array($this, 'fireExternalSign'));

Parameter List

 '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(); };

KnownKeyReceived Event (SecureBlackbox_SSHClient Class)

Signals that the server has introduced itself with a known key.

Object Oriented Interface

public function fireKnownKeyReceived($param);

Procedural Interface

secureblackbox_sshclient_register_callback($res, 13, array($this, 'fireKnownKeyReceived'));

Parameter List

 'algorithm'
 'bits'
 'fingerprintsha256'

Remarks

The class fires this event to tell the application that the server has introduced itself with a known key from TrustedKeysFile.

The details of the key are provided: Algorithm and Bits specify the key algorithm and the number of bits. FingerprintSHA256 contains the key's fingerprint.

Use ServerKey to access more key details.

Notification Event (SecureBlackbox_SSHClient Class)

This event notifies the application about an underlying control flow event.

Object Oriented Interface

public function fireNotification($param);

Procedural Interface

secureblackbox_sshclient_register_callback($res, 14, array($this, 'fireNotification'));

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.

PasswordChangeRequest Event (SecureBlackbox_SSHClient Class)

Parameter List

 'prompt'
 'newpassword'
 'cancel'

Remarks

This event is fired by the class when a password change is requested by the server. Prompt contains the password prompt message. Handler should either provide the new password via NewPassword, or deny the request by setting Cancel to true.

PrivateKeyNeeded Event (SecureBlackbox_SSHClient Class)

This event is fired when client's public key was accepted by the server, but the corresponding secret key is not available.

Object Oriented Interface

public function firePrivateKeyNeeded($param);

Procedural Interface

secureblackbox_sshclient_register_callback($res, 16, array($this, 'firePrivateKeyNeeded'));

Parameter List
