The TLSServer component implements server-side functionality of the TLS protocol. In the TLS-disabled mode it works as a plain TCP server.

Syntax

TsbxTLSServer

Remarks

Use this component to accept TLS-encrypted or plain TCP connections in your application.

Follow the below steps to set up and run the server in your code:

• Create an instance of the server component and set up the license, if assumed by the edition you are using: var server = new Tlsserver(); server.RuntimeLicense = "5342..0000";
• Set up the listening port (make sure it is not in use): server.Port = 3456;
• Tell the component whether TLS connections should be enforced: server.UseTLS = false; // set to true to enable TLS
• (TLS-enabled servers only) Configure TLS parameters. The exact way of doing that may vary for different scenarios and security requirements. At the very least you need to set up the certificate chain that the server will use to authenticate itself to connecting clients. If you don"t, the component will generate a dummy certificate itself, however, that certificate is unlikely to pass any security requirements. It will let you accept test connections though.

  Below is an example of tuning up the TLS parameters of the server: // *** Switching TLS on and enabling the implicit mode *** server.UseTLS = true; server.TLSSettings.TLSMode = smImplicitTLS; // Loading the certificate chain var mgr = new Certificatemanager(); mgr.RuntimeLicense = "5342..0000"; // *** Setting up the host certificate *** // - it should be issued in the name that matches the hostname (such as domain.com) or its IP address (1.2.3.4), // - it must have an associated private key - so likely is provided in PFX or PEM format. mgr.ImportFromFile("CertTLSServer.pfx", "password"); server.ServerCertificates.Add(mgr.Certificate); // The CA certificate: this is to help connecting clients validate the chain. mgr.ImportFromFile("CertCA.cer", ""); server.ServerCertificates.Add(mgr.Certificate); // *** Adjusting finer-grained TLS settings *** // - session resumption (allows for faster handshakes for connections from the same origin) server.TLSSettings.UseSessionResumption = true; // - secure configuration server.TLSSettings.BaseConfiguration = stpcHighlySecure; // - disabling a cipher suite we dislike (just because we can): server.TLSSettings.Ciphersuites = "-DHE_RSA_AES128_SHA" // *** Configuring versions *** // The default version setting at the time of writing (May 2021) is TLS 1.2 and TLS 1.3, // but that may change in future versions. The following tune-up additionally activates TLS 1.1 and TLS 1.0, // which weakens security, but may be necessary to accept connections from older clients: server.TLSSettings.Versions = csbTLS1 | csbTLS11 | csbTLS12 | csbTLS13;

• Now that your server has been fully set up, activate it: server.Start();
• Once the Start call completes, your server can accept connections from clients. Each accepted connection runs in a separate thread, not interfering with each other or your own threads. The server communicates its ongoing activities to your application by throwing events:
  • Accept to notify you about a new incoming connection. This event lets you accept or reject it.
  • Connect to notify your code of an accepted connection. This event introduces a ConnectionID, a unique identifier that you can use to track the connection throughout its lifetime.
  • Disconnect to notify you that a connection has been closed.
  • TLSEstablished and TLSShutdown to let you know that a TLS layer has been activated/deactivated.
  • Data to notify you about a piece of data received from the remote side.
  • Error to report a protocol or other error.
  • CertificateValidate to communicate the client authentication event to your code. To access the certificate(s) provided by the authenticating client, pin the client and use the PinnedClientChain property to access its chain: server.PinClient(e.ConnectionID); e.Accept = CheckCert(server.PinnedClientChain);

  Note: every such event is thrown from the respective connection thread, so make sure you use some synchronization mechanism when dispatching the events to your UI thread - for example, by updating UI controls by sending a Window Message rather than accessing the controls directly.

  Use SendData and SendText to send data back to a client. When sending data, provide the ConnectionID that is associated with that client. Call DropClient to terminate a client connection.

• To stop the server, call Stop: server.Stop();

TLSServer and SSLLabs

Qualys SSLLabs (https://www.ssllabs.com/) has been long known as a comprehensive TLS site quality checking tool. It is now a de-facto standard and a sign of good taste to aspire for the best SSLLabs test result for your web presence. SecureBlackbox developers share that effort and want to help their customers build secure TLS endpoints that can be independently endorsed by third-party evaluators like SSLLabs.

Having said that, when assessing SecureBlackbox TLS-capable servers that are configured to use their default setup, you will often end up with a lower SSLLabs score than you could have. There is a simple reason for that. Being a vendor of a library used by thousands of customers, we have to find a delicate balance between security, compatibility, and keeping class contracts rolling from one product build to another. This makes the default configuration of the components not the strongest possible. To put it simple, we could easily make the default component setup bulletproof - but having done that, we would have likely ended up with hundreds of customers stuck with legacy environments (and there are a lot of them around) losing their connectivity.

If you are looking at achieving the best score at SSLLabs, please read on. The below guidance aims to help you tune up the server component in the way that should give you an A score.

First, switch your server to the highly secure base configuration: server.TLSSettings.BaseConfiguration = stpcHighlySecure; This should immediately give you an A, or a T if your server certificate does not chain up to a trusted anchor.

Some warnings will still be included in the report. One of those is related to the session resumption. It is normally shown in orange:

Session resumption (caching): No (IDs assigned but not accepted)

This literally means that the server is not configured to re-use older sessions, which may put extra computational burden on clients and itself. Use the following setting to enable session caching: server.TLSSettings.UseSessionResumption = true;

Besides, the report may show that there are some weak ciphersuites. All of those should be shown in orange (there should not be any reds; if there are - please let us know), which means they are only relatively weak. While switching them off may affect the interoperability level of the server, you may still want to do that. By using the below approach you can disable individual ciphersuites selectively. For example, if the report shows that TLS_DHE_RSA_WITH_AES128_CBC_SHA256 and TLS_DHE_RSA_WITH_AES256_CBC_SHA256 are weak (because of their CBC mode), you can disable them in the following way: server.TLSSettings.Ciphersuites = '-DHE_RSA_AES128_SHA256;-DHE_RSA_AES256_SHA256'; Note that SBB uses slightly different, simpler naming convention by dropping unnecessart WITH and CBC. Let us know if you have difficulties matching the cipher suite names.

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 (TLSServer Component)

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 PinnedClientCertSubjectKeyID setting, and for lower-level certificates, from the parent certificate's subject key ID extension.

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

Syntax

__property TsbxTLSServerTLSRevocationChecks TLSRevocationCheck = { read=FTLSRevocationCheck, write=FSetTLSRevocationCheck };

enum TsbxTLSServerTLSRevocationChecks {
  crcNone=0,
  crcAuto=1,

  crcAnyOCSP=6,
  crcAnyCRLOrOCSP=7,
  crcAnyOCSPOrCRL=8
};

Default Value

crcAuto

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.

This property is not available at design time.

Config Method (TLSServer Component)

Sets or retrieves a configuration setting.

Syntax

String __fastcall Config(String ConfigurationString);

Remarks

Config is a generic method available in every component. It is used to set and retrieve configuration settings for the component.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, 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.

DoAction Method (TLSServer Component)

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:

DropClient Method (TLSServer Component)

Terminates a client connection.

Syntax

ExportKeyMaterial Method (TLSServer Component)

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

Syntax

void __fastcall ExportKeyMaterial(__int64 ConnectionID, String Lbl, DynamicArray<Byte> Context, int Len);

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.

ListClients Method (TLSServer Component)

} TsbxTLSServerConnectEventParams;
typedef void __fastcall (__closure *TsbxTLSServerConnectEvent)(System::TObject* Sender, TsbxTLSServerConnectEventParams *e);
__property TsbxTLSServerConnectEvent OnConnect = { read=FOnConnect, write=FOnConnect };

Remarks

The component fires this event to report that a new connection has been established. ConnectionId indicates the unique ID assigned to this connection. The same ID will be supplied to any other events related to this connection, such as TLSHandshake or Data.

Data Event (TLSServer Component)

Supplies a data chunk received from a client.

Syntax

typedef struct {
  __int64 ConnectionID;
  DynamicArray Buffer;
} TsbxTLSServerDataEventParams;

ExternalSign Event (TLSServer Component)

Handles remote or external signing initiated by the server protocol.

Syntax

typedef struct {
  __int64 ConnectionID;
  String OperationId;
  String HashAlgorithm;
  String Pars;
  String Data;
  String SignedData;
} TsbxTLSServerExternalSignEventParams;
typedef void __fastcall (__closure *TsbxTLSServerExternalSignEvent)(System::TObject* Sender, TsbxTLSServerExternalSignEventParams *e);
__property TsbxTLSServerExternalSignEvent OnExternalSign = { read=FOnExternalSign, write=FOnExternalSign };

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 component via the SignedData parameter.

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

The component 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(); };

Notification Event (TLSServer Component)

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

Syntax

typedef struct {
  String EventID;
  String EventParam;
} TsbxTLSServerNotificationEventParams;
typedef void __fastcall (__closure *TsbxTLSServerNotificationEvent)(System::TObject* Sender, TsbxTLSServerNotificationEventParams *e);
__property TsbxTLSServerNotificationEvent OnNotification = { read=FOnNotification, write=FOnNotification };

Remarks

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

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

TLSCertValidate Event (TLSServer Component)
