# Struct secureblackbox::WebSocketServer

The WebSocketServer struct provides the server-side functionality of the WebSocket protocol.

## Syntax

```text
secureblackbox::WebSocketServer
```

## Remarks

Use this component to accept secure WebSocket connections in your application.

WebSocket is an Internet technology that lets you build a data exchange channel over an HTTP connection. As such, WebSocket provides a firewall-friendly way to exchange non-HTTP data between remote parties.

The task of configuring the WebSocket server component can be split into three subtasks:

- configuring HTTP parameters,
- configuring TLS parameters (for secure connections),
- configuring WebSocket parameters.

**Configuring HTTP parameters**

The primary HTTP parameters are [host](#host-property-websocketserver-struct) and [port](#port-property-websocketserver-struct), which define the endpoint that your WebSocket server will be using. If you intend to authenticate users connecting to the endpoint using one of the supported HTTP authentication methods, please look into adjusting [auth_types](#auth_types-property-websocketserver-struct) and users properties and [on_auth_attempt](#on_auth_attempt-event-websocketserver-struct) event.

**Configuring TLS parameters**

TLS support requires that you set up a server-side certificate. This certificate needs to have an associated private key. You can either obtain it from a registered CA, or generate it yourself. Attach the certificate, together with its associated chain, to the tls_server_chain collection.

General TLS properties, such as protocol versions and ciphersuite, can be adjusted via the tls_settings object. If you are looking to authenticate your clients using TLS certificates, subscribe to [on_tls_cert_validate](#on_tls_cert_validate-event-websocketserver-struct) event to intercept the client handshakes and check the certificates in the event handler.

**Configuring WebSocket parameters**

This includes subscribing to [on_web_socket_connect](#on_web_socket_connect-event-websocketserver-struct) and [on_web_socket_disconnect](#on_web_socket_disconnect-event-websocketserver-struct), as well as [on_binary_data](#on_binary_data-event-websocketserver-struct) and [on_text_data](#on_text_data-event-websocketserver-struct) events.

The first two events fire to report clients as they connect and disconnect from your server. The [on_web_socket_connect](#on_web_socket_connect-event-websocketserver-struct) client includes the connection parameters, which you can use to verify or authorize clients. The further two events notify you of any data received from the clients.

Each client is identified by a unique *Connection ID*. Use the connection ID to:

- Access client details: pass it to [pin_client](#pin_client-method-websocketserver-struct), and then access the details via pinned_client and pinned_client_chain properties.
- Send data back to a particular client by passing it to [send_data](#send_data-method-websocketserver-struct), [send_text](#send_text-method-websocketserver-struct), and [send_keep_alive](#send_keep_alive-method-websocketserver-struct) methods.
- Force client disconnect by passing it to [drop_client](#drop_client-method-websocketserver-struct) method.

Once you have set up all the connecting parameters, call [start](#start-method-websocketserver-struct) to activate the server. The server runs in a separate thread, so the call is non-blocking. To shut down the server, call [stop](#stop-method-websocketserver-struct).

### Object Lifetime

 The *new()* method returns a mutable reference to a struct instance. The object itself is kept in the global list maintained by SecureBlackbox. Due to this, the WebSocketServer struct cannot be disposed of automatically. Please, call the *dispose(&mut; self)* method of WebSocketServer when you have finished using the instance.

## Data Type

String

# external_crypto_key_id property ([WebSocketServer](#struct-secureblackboxwebsocketserver) Struct)

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

## Syntax

*Rust Syntax*

```text
fn external_crypto_key_id(&self ) -> Result<String, SecureBlackboxError> fn set_external_crypto_key_id(&self, value : &str) ->  Option<SecureBlackboxError>
fn set_external_crypto_key_id_ref(&self, value : &String) ->  Option<SecureBlackboxError>
```

## Default Value

""

## 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 [external_crypto_key_secret](#external_crypto_key_secret-property-websocketserver-struct) 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:

```text
  signer.ExternalCrypto.KeyID = "MainSigningKey";
  signer.ExternalCrypto.KeySecret = "abcdef0123456789";
```

## Data Type

String

# external_crypto_key_secret property ([WebSocketServer](#struct-secureblackboxwebsocketserver) Struct)

The pre-shared key used for DC request authentication.

## Syntax

*Rust Syntax*

```text
fn external_crypto_key_secret(&self ) -> Result<String, SecureBlackboxError> fn set_external_crypto_key_secret(&self, value : &str) ->  Option<SecureBlackboxError>
fn set_external_crypto_key_secret_ref(&self, value : &String) ->  Option<SecureBlackboxError>
```

## Default Value

""

## Remarks

The pre-shared key used for DC request authentication. This key must be set and match the key used by the DCAuth counterpart for the scheme to work.

Read more about configuring authentication in the [external_crypto_key_id](#external_crypto_key_id-property-websocketserver-struct) topic.

## Data Type

String

# external_crypto_method property ([WebSocketServer](#struct-secureblackboxwebsocketserver) Struct)

| asmdPKCS7 | 1 |

## Data Type

i32

# external_crypto_mode property ([WebSocketServer](#struct-secureblackboxwebsocketserver) Struct)

# external_crypto_public_key_algorithm property ([WebSocketServer](#struct-secureblackboxwebsocketserver) Struct)

Provide the public key algorithm here if the certificate is not available on the pre-signing stage.

## Syntax

*Rust Syntax*

```text
fn external_crypto_public_key_algorithm(&self ) -> Result<String, SecureBlackboxError> fn set_external_crypto_public_key_algorithm(&self, value : &str) ->  Option<SecureBlackboxError>
fn set_external_crypto_public_key_algorithm_ref(&self, value : &String) ->  Option<SecureBlackboxError>

```

## Remarks

A unique identifier (fingerprint) of the CA certificate's cryptographic key.

Authority Key Identifier is a certificate extension which allows identification of certificates belonging to the same issuer, but with different public keys. It is a de-facto standard to include this extension in all certificates to facilitate chain building.

This setting cannot be set when generating a certificate as it always derives from another certificate property. [CertificateManager](#CertificateManager) generates this setting automatically if enough information is available to it: for self-signed certificates, this value is copied from the [pinned_client_cert_subject_key_id](#pinned_client_cert_subject_key_id-property-websocketserver-struct) setting, and for lower-level certificates, from the parent certificate's subject key ID extension.

The *PinnedClientCertIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [PinnedClientCertCount](#pinned_client_cert_count-property-websocketserver-struct) property.

fn pinned_client_cert_subject_key_id(&self , PinnedClientCertIndex : i32) -> Result<Vec<u8>, SecureBlackboxError>
```

## Remarks

Contains a unique identifier of the certificate's cryptographic key.

Subject Key Identifier is a certificate extension which allows a specific public key to be associated with a certificate holder. Typically, subject key identifiers of CA certificates are recorded as respective CA key identifiers in the subordinate certificates that they issue, which facilitates chain building.

The [pinned_client_cert_subject_key_id](#pinned_client_cert_subject_key_id-property-websocketserver-struct) and [pinned_client_cert_ca_key_id](#pinned_client_cert_ca_key_id-property-websocketserver-struct) properties of self-signed certificates typically contain identical values, as in that specific case, the issuer and the subject are the same entity.

The *PinnedClientCertIndex* parameter specifies the index of the item in the array. The size of the array is controlled by the [PinnedClientCertCount](#pinned_client_cert_count-property-websocketserver-struct) property.

This property is read-only.

## Data Type

```

## Default Value

""

## Remarks

A list of ciphersuites separated with commas or semicolons. Each ciphersuite in the list may be prefixed with a minus sign (-) to indicate that the ciphersuite should be disabled rather than enabled. Besides the specific ciphersuite modifiers, this property supports the *all* (and *-all*) aliases, allowing all ciphersuites to be blanketly enabled or disabled at once.

Note: the list of ciphersuites provided to this property alters the baseline list of ciphersuites as defined by [tls_base_configuration](#tls_base_configuration-property-websocketserver-struct). Remember to start your ciphersuite string with -all; if you need to only enable a specific fixed set of ciphersuites. The list of supported ciphersuites is provided below:

```

## Default Value

1

## Remarks

Specifies the kind(s) of revocation check to perform.

Revocation checking is necessary to ensure the integrity of the chain and obtain up-to-date certificate validity and trustworthiness information.

|  |  |  |
| --- | --- | --- |
| crcNone | 0 | No revocation checking. |
| crcAuto | 1 | Automatic mode selection. Currently this maps to crcAnyOCSPOrCRL, but it may change in the future. |
| crcAllCRL | 2 | All provided CRL endpoints will be checked, and all checks must succeed. |
| crcAllOCSP | 3 | All provided OCSP endpoints will be checked, and all checks must succeed. |
| crcAllCRLAndOCSP | 4 | All provided CRL and OCSP endpoints will be checked, and all checks must succeed. |
| crcAnyCRL | 5 | All provided CRL endpoints will be checked, and at least one check must succeed. |
| crcAnyOCSP | 6 | All provided OCSP endpoints will be checked, and at least one check must succeed. |
| crcAnyCRLOrOCSP | 7 | All provided CRL and OCSP endpoints will be checked, and at least one check must succeed. CRL endpoints are checked first. |
| crcAnyOCSPOrCRL | 8 | All provided CRL and OCSP endpoints will be checked, and at least one check must succeed. OCSP endpoints are checked first. |

This setting controls the way the revocation checks are performed for every certificate in the chain. Typically certificates come with two types of revocation information sources: CRL (certificate revocation lists) and OCSP responders. CRLs are static objects periodically published by the CA at some online location. OCSP responders are active online services maintained by the CA that can provide up-to-date information on certificate statuses in near real time.

There are some conceptual differences between the two. CRLs are normally larger in size. Their use involves some latency because there is normally some delay between the time when a certificate was revoked and the time the subsequent CRL mentioning that is published. The benefits of CRL is that the same object can provide statuses for all certificates issued by a particular CA, and that the whole technology is much simpler than OCSP (and thus is supported by more CAs).

This setting lets you adjust the validation course by including or excluding certain types of revocation sources from the validation process. The crcAnyOCSPOrCRL setting (give preference to the faster OCSP route and only demand one source to succeed) is a good choice for most typical validation environments. The "crcAll*" modes are much stricter, and may be used in scenarios where bulletproof validity information is essential.

NOTE: If no CRL or OCSP endpoints are provided by the CA, the revocation check will be considered successful. This is because the CA chose not to supply revocation information for its certificates, meaning they are considered irrevocable.

NOTE: Within each of the above settings, if any retrieved CRL or OCSP response indicates that the certificate has been revoked, the revocation check fails.

Sets or retrieves a configuration setting.

## Syntax

*Rust Syntax*

```text
fn config(&self, configuration_string : &str) ->  Result<String, SecureBlackboxError>
```

## Remarks

config is a generic method available in every struct. It is used to set and retrieve [configuration settings](#config-settings-websocketserver-struct) for the struct.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the struct, 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](#config-settings-websocketserver-struct), you must call *Config("PROPERTY")*. The value will be returned as a string.

# do_action method ([WebSocketServer](#struct-secureblackboxwebsocketserver) Struct)

Performs an additional action.

## Syntax

*Rust Syntax*

```text
fn do_action(&self, action_id : &str, action_params : &str) ->  Result<String, SecureBlackboxError>
```

## Remarks

do_action is a generic method available in every struct. 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;...*.

Common ActionIDs:

|  |  |  |  |
| --- | --- | --- | --- |
| Action | Parameters | Returned value | Description |
| ResetTrustedListCache | none | none | Clears the cached list of trusted lists. |
| ResetCertificateCache | none | none | Clears the cached certificates. |
| ResetCRLCache | none | none | Clears the cached CRLs. |
| ResetOCSPResponseCache | none | none | Clears the cached OCSP responses. |

  pub fn set_on_disconnect(&mut self, value : &'a dyn WebSocketServerDisconnectEvent);
  ...
}
```

## Remarks

The struct fires this event when a connected client disconnects.

# on_error event ([WebSocketServer](#struct-secureblackboxwebsocketserver) Struct)

Information about errors during data delivery.

## Syntax

*Rust Syntax*

```text
// WebSocketServerErrorEventArgs carries the WebSocketServer Error event's parameters.
pub struct WebSocketServerErrorEventArgs {
  fn connection_id(&self) -> i64
  fn error_code(&self) -> i32
  fn fatal(&self) -> bool
  fn remote(&self) -> bool
  fn description(&self) -> &String
}

// WebSocketServerErrorEvent defines the signature of the WebSocketServer Error event's handler function.
pub trait WebSocketServerErrorEvent {
  fn on_error(&self, sender : WebSocketServer, e : &mut WebSocketServerErrorEventArgs);
}

impl <'a> WebSocketServer<'a> {
  pub fn on_error(&self) -> &'a dyn WebSocketServerErrorEvent;
  pub fn set_on_error(&mut self, value : &'a dyn WebSocketServerErrorEvent);
  ...
}
```

## Remarks

The event is fired in case of exceptional conditions during message processing.

*ErrorCode* contains an error code and *Description* contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the [HTTPS](#trappable-errors-websocketserver-struct) section.

# on_external_sign event ([WebSocketServer](#struct-secureblackboxwebsocketserver) Struct)

Handles remote or external signing initiated by the server protocol.

## Syntax

*Rust Syntax*

```text
// WebSocketServerExternalSignEventArgs carries the WebSocketServer ExternalSign event's parameters.
pub struct WebSocketServerExternalSignEventArgs {
  fn connection_id(&self) -> i64
  fn operation_id(&self) -> &String
  fn hash_algorithm(&self) -> &String
  fn pars(&self) -> &String
  fn data(&self) -> &String
  fn signed_data(&self) -> &String
  fn set_signed_data(&self, value : &str)
  fn set_signed_data_ref(&self, value : &String)
}

// WebSocketServerExternalSignEvent defines the signature of the WebSocketServer ExternalSign event's handler function.
pub trait WebSocketServerExternalSignEvent {
  fn on_external_sign(&self, sender : WebSocketServer, e : &mut WebSocketServerExternalSignEventArgs);
}

impl <'a> WebSocketServer<'a> {
  pub fn on_external_sign(&self) -> &'a dyn WebSocketServerExternalSignEvent;
  pub fn set_on_external_sign(&mut self, value : &'a dyn WebSocketServerExternalSignEvent);
  ...
}
```

## 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 struct via the *SignedData* parameter.

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

The struct 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:

```text
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();
};
```

# on_get_request event ([WebSocketServer](#struct-secureblackboxwebsocketserver) Struct)

Reports a GET request.

## Syntax

*Rust Syntax*

```text
// WebSocketServerGetRequestEventArgs carries the WebSocketServer GetRequest event's parameters.
pub struct WebSocketServerGetRequestEventArgs {
  fn connection_id(&self) -> i64
  fn uri(&self) -> &String
  fn handled(&self) -> bool
  fn set_handled(&self, value : bool)
}

// WebSocketServerGetRequestEvent defines the signature of the WebSocketServer GetRequest event's handler function.
pub trait WebSocketServerGetRequestEvent {
  fn on_get_request(&self, sender : WebSocketServer, e : &mut WebSocketServerGetRequestEventArgs);
}

impl <'a> WebSocketServer<'a> {
  pub fn on_get_request(&self) -> &'a dyn WebSocketServerGetRequestEvent;
  pub fn set_on_get_request(&mut self, value : &'a dyn WebSocketServerGetRequestEvent);
  ...
}
```

## Remarks

The struct fires this event to notify the application about a GET request received from the client.

*ConnectionID* indicates the connection that sent the request and *URI* suggests the requested resource.

Set *Handled* to true to indicate that your application's code will take care of the request. The application does it by providing the necessary details via [set_response_status](#set_response_status-method-websocketserver-struct), set_response_header, set_response_file or [set_response_string](#set_response_string-method-websocketserver-struct) methods. If the returned value of *Handled* is false, the server will try to take care of the request automatically by searching for the requested resource in document_root.

# on_keep_alive_response event ([WebSocketServer](#struct-secureblackboxwebsocketserver) Struct)

Reports a response to a keep-alive message.

## Syntax

*Rust Syntax*

```text
// WebSocketServerKeepAliveResponseEventArgs carries the WebSocketServer KeepAliveResponse event's parameters.
pub struct WebSocketServerKeepAliveResponseEventArgs {
  fn connection_id(&self) -> i64
}

// WebSocketServerKeepAliveResponseEvent defines the signature of the WebSocketServer KeepAliveResponse event's handler function.
pub trait WebSocketServerKeepAliveResponseEvent {
  fn on_keep_alive_response(&self, sender : WebSocketServer, e : &mut WebSocketServerKeepAliveResponseEventArgs);
}

impl <'a> WebSocketServer<'a> {
  pub fn on_keep_alive_response(&self) -> &'a dyn WebSocketServerKeepAliveResponseEvent;
  pub fn set_on_keep_alive_response(&mut self, value : &'a dyn WebSocketServerKeepAliveResponseEvent);
  ...
}
```

## Remarks

This event is triggered when a response to a previously sent keep-alive message is received.

# on_notification event ([WebSocketServer](#struct-secureblackboxwebsocketserver) Struct)

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

## Syntax

*Rust Syntax*

```text
// WebSocketServerNotificationEventArgs carries the WebSocketServer Notification event's parameters.
pub struct WebSocketServerNotificationEventArgs {
  fn event_id(&self) -> &String
  fn event_param(&self) -> &String
}

// WebSocketServerNotificationEvent defines the signature of the WebSocketServer Notification event's handler function.
pub trait WebSocketServerNotificationEvent {
  fn on_notification(&self, sender : WebSocketServer, e : &mut WebSocketServerNotificationEventArgs);
}

impl <'a> WebSocketServer<'a> {
  pub fn on_notification(&self) -> &'a dyn WebSocketServerNotificationEvent;
  pub fn set_on_notification(&mut self, value : &'a dyn WebSocketServerNotificationEvent);
  ...
}
```

## Remarks

The struct fires this event to let the application know about some event, occurrence, or milestone in the struct. 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 struct, the exact action it is performing, or the document being processed, one or both may be omitted.

This struct can fire this event with the following *EventID* values:

|  |  |
| --- | --- |
| Open | Notifies the application about an established websocket request. This is a backward-compatibility-only notification: use OnWebSocketConnect event to get that notification instead. |
| Close | Notifies the application that a websocket connection was closed. This is a backward-compatibility-only notification. Use OnWebSocketDisconnect event instead. |

# on_text_data event ([WebSocketServer](#struct-secureblackboxwebsocketserver) Struct)

Passes a received chunk of text data to the application.

## Syntax

*Rust Syntax*

```text
// WebSocketServerTextDataEventArgs carries the WebSocketServer TextData event's parameters.
pub struct WebSocketServerTextDataEventArgs {
  fn connection_id(&self) -> i64
  fn text(&self) -> &String
  fn last(&self) -> bool
}

// WebSocketServerTextDataEvent defines the signature of the WebSocketServer TextData event's handler function.
pub trait WebSocketServerTextDataEvent {
  fn on_text_data(&self, sender : WebSocketServer, e : &mut WebSocketServerTextDataEventArgs);
}

impl <'a> WebSocketServer<'a> {
  pub fn on_text_data(&self) -> &'a dyn WebSocketServerTextDataEvent;
  pub fn set_on_text_data(&mut self, value : &'a dyn WebSocketServerTextDataEvent);
  ...
}
```

## Remarks

The struct fires this event repeatedly to pass incoming pieces of text data to the application. The *Last* parameter indicates that this is the last chunk.

Fires when a client certificate needs to be validated.

## Syntax

*Rust Syntax*

```text
// WebSocketServerTLSCertValidateEventArgs carries the WebSocketServer TLSCertValidate event's parameters.
pub struct WebSocketServerTLSCertValidateEventArgs {
  fn connection_id(&self) -> i64
  fn accept(&self) -> bool
  fn set_accept(&self, value : bool)
}

// WebSocketServerTLSCertValidateEvent defines the signature of the WebSocketServer TLSCertValidate event's handler function.
pub trait WebSocketServerTLSCertValidateEvent {
  fn on_tls_cert_validate(&self, sender : WebSocketServer, e : &mut WebSocketServerTLSCertValidateEventArgs);
}

  pub fn on_tls_cert_validate(&self) -> &'a dyn WebSocketServerTLSCertValidateEvent;
  pub fn set_on_tls_cert_validate(&mut self, value : &'a dyn WebSocketServerTLSCertValidateEvent);
  ...
}
```

## Remarks

The struct fires this event to notify the application of an authenticating client. Use the event handler to validate the certificate and pass your decision back to the server component via the *Accept* parameter.

# on_tls_established event ([WebSocketServer](#struct-secureblackboxwebsocketserver) Struct)

Reports the setup of a TLS session.

## Syntax

*Rust Syntax*

```text
// WebSocketServerTLSEstablishedEventArgs carries the WebSocketServer TLSEstablished event's parameters.
pub struct WebSocketServerTLSEstablishedEventArgs {
  fn connection_id(&self) -> i64
}

// WebSocketServerTLSEstablishedEvent defines the signature of the WebSocketServer TLSEstablished event's handler function.
pub trait WebSocketServerTLSEstablishedEvent {
  fn on_tls_established(&self, sender : WebSocketServer, e : &mut WebSocketServerTLSEstablishedEventArgs);

Fires when a newly established client connection initiates a TLS handshake.

## Syntax

*Rust Syntax*

```text
// WebSocketServerTLSHandshakeEventArgs carries the WebSocketServer TLSHandshake event's parameters.
pub struct WebSocketServerTLSHandshakeEventArgs {
  fn connection_id(&self) -> i64
  fn server_name(&self) -> &String
  fn abort(&self) -> bool
  fn set_abort(&self, value : bool)
}

// WebSocketServerTLSHandshakeEvent defines the signature of the WebSocketServer TLSHandshake event's handler function.
pub trait WebSocketServerTLSHandshakeEvent {
  fn on_tls_handshake(&self, sender : WebSocketServer, e : &mut WebSocketServerTLSHandshakeEventArgs);
}

impl <'a> WebSocketServer<'a> {
  pub fn on_tls_handshake(&self) -> &'a dyn WebSocketServerTLSHandshakeEvent;
  pub fn set_on_tls_handshake(&mut self, value : &'a dyn WebSocketServerTLSHandshakeEvent);
  ...
}
```

## Remarks

Use this event to get notified about the initiation of the TLS handshake by the remote client. The *ServerName* parameter specifies the requested host from the client hello message.

# on_tls_psk event ([WebSocketServer](#struct-secureblackboxwebsocketserver) Struct)

Requests a pre-shared key for TLS-PSK.

## Syntax

*Rust Syntax*

```text
// WebSocketServerTLSPSKEventArgs carries the WebSocketServer TLSPSK event's parameters.
pub struct WebSocketServerTLSPSKEventArgs {
  fn connection_id(&self) -> i64
  fn identity(&self) -> &String
  fn psk(&self) -> &String
  fn set_psk(&self, value : &str)
  fn set_psk_ref(&self, value : &String)
  fn ciphersuite(&self) -> &String

  pub fn on_tls_psk(&self) -> &'a dyn WebSocketServerTLSPSKEvent;
  pub fn set_on_tls_psk(&mut self, value : &'a dyn WebSocketServerTLSPSKEvent);
  ...
}
```

## Remarks

The struct fires this event to report that a client has requested a TLS-PSK negotiation. *ConnectionId* indicates the unique connection ID that requested the PSK handshake.

Use *Identity* to look up for the corresponding pre-shared key in the server's database, then assign the key to the *PSK* parameter. If TLS 1.3 PSK is used, you will also need to assign the *Ciphersuite* parameter with the cipher suite associated with that identity and their key.

# on_tls_shutdown event ([WebSocketServer](#struct-secureblackboxwebsocketserver) Struct)

Reports closure of a TLS session.

## Syntax

*Rust Syntax*

```text

  fn connection_id(&self) -> i64
}

// WebSocketServerTLSShutdownEvent defines the signature of the WebSocketServer TLSShutdown event's handler function.
pub trait WebSocketServerTLSShutdownEvent {
  fn on_tls_shutdown(&self, sender : WebSocketServer, e : &mut WebSocketServerTLSShutdownEventArgs);
}

impl <'a> WebSocketServer<'a> {
  pub fn on_tls_shutdown(&self) -> &'a dyn WebSocketServerTLSShutdownEvent;
  pub fn set_on_tls_shutdown(&mut self, value : &'a dyn WebSocketServerTLSShutdownEvent);
  ...
}
```

## Remarks

The struct fires this event when a connected client closes their TLS session gracefully. This event is typically followed by a [on_disconnect](#on_disconnect-event-websocketserver-struct), which marks the closure of the underlying TCP session.

# on_web_socket_connect event ([WebSocketServer](#struct-secureblackboxwebsocketserver) Struct)

Reports an accepted WebSocket connection.

## Syntax

*Rust Syntax*

```text
// WebSocketServerWebSocketConnectEventArgs carries the WebSocketServer WebSocketConnect event's parameters.

  pub fn on_web_socket_disconnect(&self) -> &'a dyn WebSocketServerWebSocketDisconnectEvent;
  pub fn set_on_web_socket_disconnect(&mut self, value : &'a dyn WebSocketServerWebSocketDisconnectEvent);
  ...
}
```

## Remarks

The struct fires this event when a connected WebSocket client disconnects.

# Config Settings ([WebSocketServer](#struct-secureblackboxwebsocketserver) Struct)

 The struct 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 struct, access to these *internal properties* is provided through the [config](#config-method-websocketserver-struct) method.

### WebSocketServer Config Settings

**AllowKeepAlive**: Enables or disables keep-alive mode.Use this property to enable or disable the keep-alive connection mode. If keep-alive is enabled, clients that choose to use it may stay connected for a while.

**AllowOptionsResponseWithoutAuth**: Enables unauthenticated responses to OPTIONS requests.Set this property to true to allow the server serve OPTIONS requests without prior authentication of the client.

**AuthBasic**: Turns on/off the basic authentication.When switched on, connecting clients can use the basic authentication.

**AuthDigest**: Turns on/off the digest authentication.When switched on, connecting clients can use the digest authentication.

**AuthDigestExpire**: Specifies digest expiration time for digest authentication.Use this property to specify the digest expiration time for digest authentication, in seconds. The default setting is 20.

**AuthRealm**: Specifies authentication realm for digest and NTLM authentication.Specifies authentication realm for digest and NTLM authentication types.

**BoundAddress**: Returns the bound address of the listening socket.Use this property to obtain the bound address of the listening socket.

**BoundPort**: The port that was bound by the server.Returns the port number that was bound by the server.

**CompressionLevel**: The default compression level to use.Assign this property with the compression level (1 to 9) to apply for gzipped responses. 1 stands for the lightest but fastest compression, and 9 for the best but the slowest.

**DocumentRoot**: The document root of the server.Use this property to specify a local folder which is going to be the server's document root (the mount point of the virtual home directory).

**DualStack**: Allows the use of ip4 and ip6 simultaneously.This setting specifies a socket can use ip4 and ip6 simultaneously.

**HandshakeTimeout**: The HTTPS handshake timeout.The HTTPS handshake timeout in milliseconds.

**HomePage**: Specifies the home page resource name.Use this property to specify the home page (/) resource name.

**Host**: The host to bind to.Specifies a specific interface the server should listen on.

**OAuthAllowAccessByDefault**: Specifies whether access to a resource is allowed by default.Use this property to enable or disable access to a resource in case if no scopes defined or the resource doesn't match any of the user's scopes.

**OAuthAutoValidateTokens**: Allows to validate OAuth 2.0 access tokens automatically.Use this property to enable or disable pre-validation of access tokens.

**OAuthIntrospectionClientID**: Specifies a client ID on the authentication service.Use this property to provide a client ID for access token introspection.

**OAuthIntrospectionClientSecret**: Specifies a client secret on the authentication service.Use this property to provide a client secret for access token introspection.

**OAuthIntrospectionURL**: Specifies the URL to be used to introspect access tokens.Use this property to provide the URL for introspection.

**OAuthTokenValidationKeys**: Specifies JW keys in JSON format for validating access token signatures.

**Port**: The port to listen on.This config setting mimics the Port property. Please use that instead.

**PortRangeFrom**: The lower bound of allowed port scope to listen on.Specifies the lowest port number the server may use if dynamic allocation is used.

**PortRangeTo**: The higher bound of allowed port scope to listen on.Specifies the highest port number the server may use if dynamic allocation is used.

**PreSharedIdentityHint**: Gets or sets the PSK identity hint.Use this property to get or set the PSK identity hint to be used during PSK-based TLS handshake.

**RequestFilter**: The request string modifier.Use this property to tune up the request string as returned by GetRequestString method. Supported filters: params (request parameters only), params[Index] or params['Name'] (a specific request parameter), parts[Index] (the contents of a particular part of a multipart message). An empty request filter makes GetRequestString return the whole body of the request.

**SessionTimeout**: The HTTP session timeout.The HTTP session timeout in milliseconds.

**SleepLen**: Adjusts the server loop idling time.Use this property to adjust the server connection loop idling time between consecutive connection read calls. Increasing this setting may help combat excessive CPU usage in performance-restricted or busy environments. Setting it to zero removes the idling altogether, which maximizes the throughput but may cause excessive CPU load.

**TempDir**: A temporary directory to use.Specifies the temporary directory to use during server operation.

**TempPath**: Path for storing temporary files.This setting specifies an absolute path to the location on disk where temporary files are stored. This setting is supported only in the Java edition for all applicable signing components except [PDFSigner](PDFSigner.md#PDFSigner), where this limitation does not apply.

**TLSCiphersuites**: Returns the list of ciphersuites activated in the component for the current session.Check this property to enumerate the list of TLS ciphersuites enabled in the component. A good place to do that is OnTLSHandshake event handler.

**TLSExtensions**: TBD.TBD

**TLSGroups**: Returns the list of TLS key exchange groups enabled in the component.Check this property to enumerate the list of TLS key exchange groups enabled in the component.

**TLSPeerExtensions**: TBD.TBD

**TLSServerCertIndex**: Specifies the index of the server certificate to use.This setting allows your code to specify the exact certificate/chain to use for the TLS handshake that has just commenced, if your server is configured with more than one chain. This property should typically be adjusted from within the OnTLSHandshake event handler.

Note: the server component normally picks up the most appropriate certificate automatically. This setting is a wiretap for scenarios where unusual or cherry-picked certificate selection logic may be necessary.

**TLSVersions**: Returns the list of TLS versions enabled in the component.Check this property to obtain the list of TLS versions enabled in the component, as an integer bitmask.

**UseChunkedTransfer**: Enables chunked transfer.Use this property to enable chunked content encoding.

**UseCompression**: Enables or disables server-side compression.Use this property to enable or disable server-side content compression.

**WebsiteName**: The website name for the TLS certificate.Assign this property with a name to put in a self-generated TLS certificate.

### Base Config Settings

**ASN1UseGlobalTagCache**: Controls whether ASN.1 module should use a global object cache.This is a performance setting. It is unlikely that you will ever need to adjust it.

**AssignSystemSmartCardPins**: Specifies whether CSP-level PINs should be assigned to CNG keys.This is a low-level tweak for certain cryptographic providers. It is unlikely that you will ever need to adjust it.

**CheckKeyIntegrityBeforeUse**: Enables or disable private key integrity check before use.This global property enables or disables private key material check before each signing operation. This slows down performance a bit, but prevents a selection of attacks on RSA keys where keys with unknown origins are used.

You can switch this property off to improve performance if your project only uses known, good private keys.

**CookieCaching**: Specifies whether a cookie cache should be used for HTTP(S) transports.Set this property to enable or disable cookies caching for the struct.

Supported values are:

|  |  |  |
| --- | --- | --- |
| off |  | No caching (default) |
| local |  | Local caching |
| global |  | Global caching |

**Cookies**: Gets or sets local cookies for the struct.Use this property to get cookies from the internal cookie storage of the struct and/or restore them back between application sessions.

**DefDeriveKeyIterations**: Specifies the default key derivation algorithm iteration count.This global property sets the default number of iterations for all supported key derivation algorithms. Note that you can provide the required number of iterations by using properties of the relevant key generation component; this global setting is used in scenarios where specific iteration count is not or cannot be provided.

**DNSLocalSuffix**: The suffix to assign for TLD names.Use this global setting to adjust the default suffix to assign to top-level domain names. The default is *.local*.

**EnableClientSideSSLFFDHE**: Enables or disables finite field DHE key exchange support in TLS clients.This global property enables or disables support for finite field DHE key exchange methods in TLS clients. FF DHE is a slower algorithm if compared to EC DHE; enabling it may result in slower connections.

This setting only applies to sessions negotiated with TLS version 1.3.

**EnableSSHMLKEM**: Enables support for ML-KEM/hybrid key exchange algorithms in SSH client and server components.Use this setting to enable hybrid key exchange algorithms in client and server SSH and SFTP components. This is a global setting that enables ML-KEM blanketly in all SSH-dependent components.

**EnableTLSMLKEM**: Enables support for ML-KEM and hybrid groups in TLS client and server components.Use this setting to enable ML-KEM and hybrid key exchange groups in client and server TLS components. This is a global setting that enables ML-KEM blanketly in all TLS-dependent components.

**GlobalCookies**: Gets or sets global cookies for all the HTTP transports.Use this property to get cookies from the GLOBAL cookie storage or restore them back between application sessions. These cookies will be used by all the structs that have its *CookieCaching* property set to "global".

**HardwareCryptoUsePolicy**: The hardware crypto usage policy.This global setting controls the hardware cryptography usage policy.

Supported Values:

|  |  |
| --- | --- |
| auto | Use hardware cryptography if available; otherwise, fall back to software-based cryptography (default). |
| enable | Always attempt to use hardware cryptography. If unavailable, exception will be thrown. |
| disable | Do not use hardware cryptography. |

**HttpUserAgent**: Specifies the user agent name to be used by all HTTP clients.This global setting defines the User-Agent field of the HTTP request provides information about the software that initiates the request. This value will be used by all the HTTP clients including the ones used internally in other structs.

**HttpVersion**: The HTTP version to use in any inner HTTP client components created.Set this property to 1.0 or 1.1 to indicate the HTTP version that any internal HTTP clients should use.

**IgnoreExpiredMSCTLSigningCert**: Whether to tolerate the expired Windows Update signing certificate.It is not uncommon for Microsoft Windows Update Certificate Trust List to be signed with an expired Microsoft certificate. Setting this global property to true makes SBB ignore the expired factor and take the Trust List into account.

**ListDelimiter**: The delimiter character for multi-element lists.Allows to set the delimiter for any multi-entry values returned by the component as a string object, such as file lists. For most of the components, this property is set to a newline sequence.

**LogDestination**: Specifies the debug log destination.Contains a comma-separated list of values that specifies where debug log should be dumped.

Supported values are:

|  |  |  |
| --- | --- | --- |
| file |  | File |

**LogRotationMode**: Specifies the log rotation mode.Use this property to set the log rotation mode. The following values are defined:

|  |  |  |
| --- | --- | --- |
| none |  | No rotation |
| deleteolder |  | Delete older entries from the cache upon reaching LogMaxEventCount |
| keepolder |  | Keep older entries in the cache upon reaching LogMaxEventCount (newer entries are discarded) |

**MaxASN1BufferLength**: Specifies the maximal allowed length for ASN.1 primitive tag data.This global property limits the maximal allowed length for ASN.1 tag data for non-content-carrying structures, such as certificates, CRLs, or timestamps. It does not affect structures that can carry content, such as CMS/CAdES messages. This is a security property aiming at preventing DoS attacks.

**MaxASN1TreeDepth**: Specifies the maximal depth for processed ASN.1 trees.This global property limits the maximal depth of ASN.1 trees that the component can handle without throwing an error. This is a security property aiming at preventing DoS attacks.

**OCSPHashAlgorithm**: Specifies the hash algorithm to be used to identify certificates in OCSP requests.This global setting defines the hash algorithm to use in OCSP requests during chain validation. Some OCSP responders can only use older algorithms, in which case setting this property to SHA1 may be helpful.

**OldClientSideRSAFallback**: Specifies whether the SSH client should use a SHA1 fallback.Tells the SSH client to use a legacy ssh-rsa authentication even if the server indicates support for newer algorithms, such as rsa-sha-256. This is a backward-compatibility tweak.

**PKICache**: Specifies which PKI elements (certificates, CRLs, OCSP responses) should be cached.The PKICache setting specifies which Public Key Infrastructure (PKI) elements should be cached to optimize performance and reduce retrieval times. It supports comma-separated values to indicate the specific types of PKI data that should be cached.

Supported Values:

|  |  |
| --- | --- |
| certificate | Enables caching of certificates. |
| crl | Enables caching of Certificate Revocation Lists (CRLs). |
| ocsp | Enables caching of OCSP (Online Certificate Status Protocol) responses. |

Example (default value):

```text
PKICache=certificate,crl,ocsp
```

 In this example, the component caches certificates, CRLs, and OCSP responses.

**PKICachePath**: Specifies the file system path where cached PKI data is stored.The PKICachePath setting defines the file system path where cached PKI data (e.g., certificates, CRLs, OCSP responses and Trusted Lists) will be stored. This allows the system to persistently save and retrieve PKI cache data, even across application restarts.

The default value is an empty string - no cached PKI data is stored on disk.

Example:

```text
PKICachePath=C:\Temp\cache
```

 In this example, the cached PKI data is stored in the C:\Temp\cache directory.

**ProductVersion**: Returns the version of the SecureBlackbox library.This property returns the long version string of the SecureBlackbox library being used (major.minor.build.revision).

**ServerSSLDHKeyLength**: Sets the size of the TLS DHE key exchange group.Use this property to adjust the length, in bits, of the DHE prime to be used by the TLS server.

**StaticDNS**: Specifies whether static DNS rules should be used.Set this property to enable or disable static DNS rules for the struct. Works only if *UseOwnDNSResolver* is set to *true*.

Supported values are:

|  |  |  |
| --- | --- | --- |
| none |  | No static DNS rules (default) |
| local |  | Local static DNS rules |
| global |  | Global static DNS rules |

**StaticIPAddress[domain]**: Gets or sets an IP address for the specified domain name.Use this property to get or set an IP address for the specified domain name in the internal (of the struct) or global DNS rules storage depending on the *StaticDNS* value. The type of the IP address (IPv4 or IPv6) is determined automatically. If both addresses are available, they are divided by the | (pipe) character.

**StaticIPAddresses**: Gets or sets all the static DNS rules.Use this property to get static DNS rules from the current rules storage or restore them back between application sessions. If *StaticDNS* of the struct is set to "*local*", the property returns/restores the rules from/to the internal storage of the struct. If *StaticDNS* of the struct is set to "*global*", the property returns/restores the rules from/to the GLOBAL storage. The rules list is returned and accepted in JSON format.

**Tag**: Allows to store any custom data.Use this config property to store any custom data.

**TLSSessionGroup**: Specifies the group name of TLS sessions to be used for session resumption.Use this property to limit the search of cached TLS sessions to the specified group. Sessions from other groups will be ignored. By default, all sessions are cached with an empty group name and available to all the structs.

**TLSSessionLifetime**: Specifies lifetime in seconds of the cached TLS session.Use this property to specify how much time the TLS session should be kept in the session cache. After this time, the session expires and will be automatically removed from the cache. Default value is 300 seconds (5 minutes).

**TLSSessionPurgeInterval**: Specifies how often the session cache should remove the expired TLS sessions.Use this property to specify the time interval of purging the expired TLS sessions from the session cache. Default value is 60 seconds (1 minute).

**UseCRLObjectCaching**: Specifies whether reuse of loaded CRL objects is enabled.This setting enables or disables the caching of CRL objects. When set to true (the default value), the system checks if a CRL object is already loaded in memory before attempting to load a new instance. If the object is found, the existing instance is reused, and its reference count is incremented to track its usage. When the reference count reaches zero, indicating that no references to the object remain, the system will free the object from memory. This setting enhances performance by minimizing unnecessary object instantiation and promotes efficient memory management, particularly in scenarios where CRL objects are frequently used.

**UseInternalRandom**: Switches between SecureBlackbox-own and platform PRNGs.Allows to switch between internal/native PRNG implementation and the one provided by the platform.

**UseLegacyAdESValidation**: Enables legacy AdES validation mode.Use this setting to switch the AdES component to the validation approach that was used in SBB 2020/SBB 2022 (less attention to temporal details).

**UseOCSPResponseObjectCaching**: Specifies whether reuse of loaded OCSP response objects is enabled.This setting enables or disables the caching of OCSP response objects. When set to true (the default value), the system checks if a OCSP response object is already loaded in memory before attempting to load a new instance. If the object is found, the existing instance is reused, and its reference count is incremented to track its usage. When the reference count reaches zero, indicating that no references to the object remain, the system will free the object from memory. This setting enhances performance by minimizing unnecessary object instantiation and promotes efficient memory management, particularly in scenarios where OCSP response objects are frequently used.

**UseOwnDNSResolver**: Specifies whether the client components should use own DNS resolver.Set this global property to false to force all the client components to use the DNS resolver provided by the target OS instead of using own one.

**UseSharedSystemStorages**: Specifies whether the validation engine should use a global per-process copy of the system certificate stores.Set this global property to false to make each validation run use its own copy of system certificate stores.

**UseSystemNativeSizeCalculation**: An internal CryptoAPI access tweak.This is an internal setting. Please do not use it unless instructed by the support team.

**UseSystemOAEPAndPSS**: Enforces or disables the use of system-driven RSA OAEP and PSS computations.This global setting defines who is responsible for performing RSA-OAEP and RSA-PSS computations where the private key is stored in a Windows system store and is exportable. If set to true, SBB will delegate the computations to Windows via a CryptoAPI call. Otherwise, it will export the key material and perform the computations using its own OAEP/PSS implementation.

This setting only applies to certificates originating from a Windows system store.

**UseSystemRandom**: Enables or disables the use of the OS PRNG.Use this global property to enable or disable the use of operating system-driven pseudorandom number generation.

**XMLRDNDescriptorName[OID]**: Defines an OID mapping to descriptor names for the certificate's IssuerRDN or SubjectRDN.This property defines custom mappings between Object Identifiers (OIDs) and descriptor names. This mapping specifies how the certificate's issuer and subject information (ds:IssuerRDN and ds:SubjectRDN elements respectively) are represented in XML signatures.

The property accepts comma-separated values where the first descriptor name is used when the OID is mapped, and subsequent values act as aliases for parsing.

Syntax:

```text
Config("XMLRDNDescriptorName[OID]=PrimaryName,Alias1,Alias2");
```

Where:

OID: The Object Identifier from the certificate's IssuerRDN or SubjectRDN that you want to map.

PrimaryName: The main descriptor name used in the XML signature when the OID is encountered.

Alias1, Alias2, ...: Optional alternative names recognized during parsing.

Usage Examples:

Map OID 2.5.4.5 to SERIALNUMBER:

```text
Config("XMLRDNDescriptorName[2.5.4.5]=SERIALNUMBER");
```

Map OID 1.2.840.113549.1.9.1 to E, with aliases EMAIL and EMAILADDRESS:

```text
Config("XMLRDNDescriptorName[1.2.840.113549.1.9.1]=E,EMAIL,EMAILADDRESS");
```

**XMLRDNDescriptorPriority[OID]**: Specifies the priority of descriptor names associated with a specific OID.This property specifies the priority of descriptor names associated with a specific OID that allows to reorder descriptors in the ds:IssuerRDN and ds:SubjectRDN elements during signing.

**XMLRDNDescriptorReverseOrder**: Specifies whether to reverse the order of descriptors in RDN.Specifies whether to reverse the order of descriptors in the ds:IssuerRDN and ds:SubjectRDN elements during XML signing. By default, this property is set to true (as specified in RFC 2253, 2.1).

**XMLRDNDescriptorSeparator**: Specifies the separator used between descriptors in RDN.Specifies the separator used between descriptors in the ds:IssuerRDN and ds:SubjectRDN elements during XML signing. By default, this property is set to ", " value.
