Syntax

secureblackbox::DTLSServer

Remarks

Use this component to receive data over a protected DTLS channel in your application.

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 DTLSServer struct cannot be disposed of automatically. Please, call the dispose(&mut self) method of DTLSServer when you have finished using the instance.

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 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";

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 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 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 property.

7   // AnyCRLOrOCSP
8   // AnyOCSPOrCRL

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.

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.

config method (DTLSServer Struct)

Sets or retrieves a configuration setting.

Syntax

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 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, you must call Config("PROPERTY"). The value will be returned as a string.

export_key_material method (DTLSServer Struct)

Derives key material from the session's master key using the TLS exporters scheme.

Syntax

fn export_key_material(&self, connection_id : i64, lbl : &str, context : &[u8], len : i32) -> Result<(), SecureBlackboxError>

Remarks

Some protocols - for example, SRTP - use the TLS exporters scheme to derive their own session keys from the TLS master key. This method lets you employ exporters to obtain such keys, or to generate secure keys for your own needs from an active TLS session.

The exported keys depend on the master key, and are different for every TLS session. However, a client and server sharing a session will always end up with the same key material, as long as they use the same values of Lbl, Context, and Len.

Use the ConnectionID parameter to specify the session that you would like to derive key material from.

list_clients method (DTLSServer Struct)

  fn connection_id(&self) -> i64
  fn error_code(&self) -> i32
  fn fatal(&self) -> bool
  fn remote(&self) -> bool
  fn description(&self) -> &String
}

// DTLSServerErrorEvent defines the signature of the DTLSServer Error event's handler function.
pub trait DTLSServerErrorEvent {

pub struct DTLSServerExternalSignEventArgs {
  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)

}

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

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: 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(); };

}

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

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

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:

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

Syntax

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

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

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

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 (DTLSServer Struct)

Requests a pre-shared key for TLS-PSK.

Syntax

// DTLSServerTLSPSKEventArgs carries the DTLSServer TLSPSK event's parameters.
pub struct DTLSServerTLSPSKEventArgs {
  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
  fn set_ciphersuite(&self, value : &str)
  fn set_ciphersuite_ref(&self, value : &String)
}

// DTLSServerTLSPSKEvent defines the signature of the DTLSServer TLSPSK event's handler function.
pub trait DTLSServerTLSPSKEvent {
  fn on_tls_psk(&self, sender : DTLSServer, e : &mut DTLSServerTLSPSKEventArgs);
}

impl <'a> DTLSServer<'a> {
  pub fn on_tls_psk(&self) -> &'a dyn DTLSServerTLSPSKEvent;
  pub fn set_on_tls_psk(&mut self, value : &'a dyn DTLSServerTLSPSKEvent);
  ...
}

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 (DTLSServer Struct)

Reports closure of a TLS session.

Syntax

// DTLSServerTLSShutdownEventArgs carries the DTLSServer TLSShutdown event's parameters.
pub struct DTLSServerTLSShutdownEventArgs {
  fn connection_id(&self) -> i64
}

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

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

Remarks

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

Config Settings (DTLSServer 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 method.
