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

Syntax

secureblackbox.Tlsserver

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.

Syntax


public int getPortRangeFrom();


public void setPortRangeFrom(int portRangeFrom);

Default Value

0

Remarks

Use this property to specify the lower limit of the port range to listen to connections on. When a port range is used to specify the listening port (as opposed to a fixed value provided via Port), the port will be allocated within the requested range by the operating system, and reported in BoundPort.

Note that this property is ignored if the Port property is set to a non-zero value, in which case the server always aims to listen on that fixed port.

PortRangeTo Property (TLSServer Class)

Specifies the upper limit of the listening port range for incoming connections.

Syntax


public int getPortRangeTo();


public void setPortRangeTo(int portRangeTo);

Default Value

Note that this property is ignored if the Port property is set to a non-zero value, in which case the server always aims to listen on that fixed port.

ServerCertificates Property (TLSServer Class)

The server's TLS certificates.

Syntax


public CertificateList getServerCertificates();


public void setServerCertificates(CertificateList serverCertificates);

Remarks

Use this property to provide a list of TLS certificates for the server endpoint.

A TLS endpoint needs a certificate to be able to accept TLS connections. At least one of the certificates in the collection - the endpoint certificate - must have a private key associated with it.

The collection may include more than one endpoint certificate, and more than one chain. A typical usage scenario is to include two chains (ECDSA and RSA), to cater for clients with different cipher suite preferences.

This property is not available at design time.

Please refer to the Certificate type for a complete list of fields.

BroadcastData Method (Tlsserver Class)

Broadcasts data to all connections.

Syntax

public void broadcastData(long connectionID, byte[] data);

Remarks

Call this method to send Data to all active client connections except for ConnectionID. Set ConnectionID to -1 to broadcast to all connections without exceptions.

BroadcastText Method (Tlsserver Class)

Broadcasts a text string to all connections.

Syntax

public void broadcastText(long connectionId, String text);

Remarks

Call this method to send Text to all active client connections except for ConnectionID. Set ConnectionID to -1 to broadcast to all connections without exceptions.

Config Method (Tlsserver Class)

Sets or retrieves a configuration setting.

Syntax

public String config(String 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.

DoAction Method (Tlsserver Class)

Performs an additional action.

Syntax

public String doAction(String actionID, String 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 insencitive) 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;....

DropClient Method (Tlsserver Class)

Terminates a client connection.

Syntax

public void dropClient(long connectionId, boolean forced);

Remarks

Call this method to shut down a connected client. Forced indicates whether the connection should be closed in a graceful manner.

ExportKeyMaterial Method (Tlsserver Class)

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

Syntax

public void exportKeyMaterial(long connectionID, String lbl, 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 Class)

Enumerates the connected clients.

Syntax

public String listClients();

Remarks

This method enumerates the connected clients. It returns a list of strings, with each string being of 'ConnectionID|Address|Port' format, and representing a single connection.

Takes a snapshot of the connection's properties.

Syntax

public void pinClient(long connectionId);

Remarks

Use this method to take a snapshot of a connected client. The captured properties are populated in PinnedClient and PinnedClientChain properties.

  ...
  public void connect(TlsserverConnectEvent e) {}
  ...
}

public class TlsserverConnectEvent {
  public long connectionID;
  public String remoteAddress;
  public int remotePort;
}

  ...
  public void data(TlsserverDataEvent e) {}
  ...
}

public class TlsserverDataEvent {
  public long connectionID;
  public byte[] buffer;
}

Remarks

  ...
  public void error(TlsserverErrorEvent e) {}
  ...
}

public class TlsserverErrorEvent {
  public long connectionID;
  public int errorCode;
  public String description;
}

  public void externalSign(TlsserverExternalSignEvent e) {}
  ...
}

public class TlsserverExternalSignEvent {
  public long connectionID;
  public String operationId;
  public String hashAlgorithm;
  public String pars;
  public String data;
  public String 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 component via 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 contain algorithm-dependent parameters.

The component uses base16 (hex) encoding for 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 a .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 Class)

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

  ...
  public void notification(TlsserverNotificationEvent e) {}
  ...
}

public class TlsserverNotificationEvent {
  public String eventID;
  public String eventParam;
}

Remarks

The class 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 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.

The class 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.

TLSShutdown Event (Tlsserver Class)

Reports closure of a TLS session.

Syntax

public class DefaultTlsserverEventListener implements TlsserverEventListener {
  ...
  public void TLSShutdown(TlsserverTLSShutdownEvent e) {}
  ...
}

public class TlsserverTLSShutdownEvent {
  public long connectionID;
}

Remarks

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

Certificate Type

Provides details of an individual X.509 certificate.

Remarks

This type provides access to X.509 certificate details.

Constructors

public Certificate( bytes,  startIndex,  count,  password);

Loads the X.509 certificate from a memory buffer. Bytes is a buffer containing the raw certificate data. StartIndex and Count specify the starting position and number of bytes to be read from the buffer, respectively. Password is a password encrypting the certificate.

public Certificate( certBytes,  certStartIndex,  certCount,  keyBytes,  keyStartIndex,  keyCount,  password);

Loads the X.509 certificate from a memory buffer. CertBytes is a buffer containing the raw certificate data. CertStartIndex and CertCount specify the number of bytes to be read from the buffer, respectively. KeyBytes is a buffer containing the private key data. KeyStartIndex and KeyCount specify the starting position and number of bytes to be read from the buffer, respectively. Password is a password encrypting the certificate.

public Certificate( bytes,  startIndex,  count);

Loads the X.509 certificate from a memory buffer. Bytes is a buffer containing the raw certificate data. StartIndex and Count specify the starting position and number of bytes to be read from the buffer, respectively.

public Certificate( path,  password);

Loads the X.509 certificate from a file. Path specifies the full path to the file containing the certificate data. Password is a password encrypting the certificate.

public Certificate( certPath,  keyPath,  password);

Loads the X.509 certificate from a file. CertPath specifies the full path to the file containing the certificate data. KeyPath specifies the full path to the file containing the private key. Password is a password encrypting the certificate.

public Certificate( path);

Loads the X.509 certificate from a file. Path specifies the full path to the file containing the certificate data.

public Certificate( stream);

Loads the X.509 certificate from a stream. Stream is a stream containing the certificate data.

public Certificate( stream,  password);

Loads the X.509 certificate from a stream. Stream is a stream containing the certificate data. Password is a password encrypting the certificate.

public Certificate( certStream,  keyStream,  password);

Loads the X.509 certificate from a stream. CertStream is a stream containing the certificate data. KeyStream is a stream containing the private key. Password is a password encrypting the certificate.

public Certificate();

Creates a new object with default field values.

ExternalCrypto Type

Specifies the parameters of external cryptographic calls.

Remarks

External cryptocalls are used in a Distributed Cryptography (DC) subsystem, which allows the delegation of security operations to the remote agent. For instance, it can be used to compute the signature value on the server, while retaining the client's private key locally.

Fields

KeyID
String

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 extra protection layer for the protocol and diminishes the risk of private key becoming abused by foreign parties. Use this property to provide the pre-shared key identifier, and use KeySecret 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";

PublicKeyAlgorithm
String

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

Fields

Ciphersuites
String

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 that allow to blanketly enable or disable all ciphersuites at once.

Note: the list of ciphersuites provided to this property alters the baseline list of ciphersuites as defined by BaseConfiguration. 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:

RevocationCheck
int

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.

crcNone0No revocation checking
crcAuto1Automatic mode selection. Currently this maps to crcAnyOCSPOrCRL, but it may change in the future.
crcAllCRL2Check all provided CRL endpoints for all chain certificates.
crcAllOCSP3Check all provided OCSP endpoints for all chain certificates.
crcAllCRLAndOCSP4Check all CRL and OCSP endpoints for all chain certificates.
crcAnyCRL5At least one CRL check for every certificate in the chain must succeed.
crcAnyOCSP6At least one OCSP check for every certificate in the chain must succeed.
crcAnyCRLOrOCSP7At least one CRL or OCSP check for every certificate in the chain must succeed. CRL endpoints are checked first.
crcAnyOCSPOrCRL8At least one CRL or OCSP check for every certificate in the chain must succeed. OCSP endpoints are checked first.

This setting controls the way the revocation checks are performed. 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 faster OCSP route and only demand one source to succeed) is a good choice for most of typical validation environments. The "crcAll*" modes are much stricter, and may be used in scenarios where bulletproof validity information is essential.

Constructors

public TLSSettings();

Creates a new TLSSettings object.

Config Settings (Tlsserver Class)

The class 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 class, access to these internal properties is provided through the Config method.

TLSServer Config Settings

ClientAuth:   Enables or disables certificate-based client authentication.

Set this property to one of the below values to tune up the client authentication logic:

0No client authentication (the default setting)
1Request certificates. The server will ask connecting clients for their certificates. Non-authenticated client connections will be accepted anyway.
2Require certificates. The server will ask connecting clients for their certificates. If a client fails to provide a certificate, the server will terminate the connection.

If this property is set to 1 or 2, the component will request certificates from the connecting clients. Depending on the setting, the clients that fail to provide their certificate in response will be allowed or disallowed to proceed with the connection. The server signals about a received certificate by firing its CertificateValidate event. Use PinClient method in the event handler to pin the client details, and access the provided certificate chain via the PinnedClientChain property.

Note that this event is fired from the connecting clients threads, so please make sure you avoid bottlenecks in the event handler and put appropriate thread safety measures in place.

Unlike the client-side components, the server component does not perform automated certificate validation against the local security policy. You must perform appropriate certificate validation steps in your CertificateValidate event handler.

DualStack:   Allows the use of ip4 and ip6 simultaneously.

This setting specifies a socket can use ip4 and ip6 simultaneously.

Host:   The host to bind to.

Specifies a specific interface the server should listen on.

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.

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

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 class.

Supported values are:

offNo caching (default)
localLocal caching (supported for HTTPClient, RESTClient and SOAPClient only)
globalGlobal caching

Cookies:   Gets or sets local cookies for the class (supported for HTTPClient, RESTClient and SOAPClient only).

Use this property to get cookies from the internal cookie storage of the class 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.

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.

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 classes that have its CookieCaching property set to "global".

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 classes.

LogDestination:   Specifies the debug log destination.

Contains a comma-separated list of values that specifies where debug log should be dumped.

Supported values are:

fileFile
consoleConsole
systemlogSystem Log (supported for Android only)
debuggerDebugger (supported for VCL for Windows and .Net)

LogDetails:   Specifies the debug log details to dump.

Contains a comma-separated list of values that specifies which debug log details to dump.

Supported values are:

timeCurrent time
levelLevel
packagePackage name
moduleModule name
classClass name
methodMethod name
threadidThread Id
contenttypeContent type
contentContent
allAll details

LogFile:   Specifies the debug log filename.

Use this property to provide a path to the log file.

LogFilters:   Specifies the debug log filters.

Contains a comma-separated list of value pairs ("name:value") that describe filters.

Supported filter names are:

exclude-packageExclude a package specified in the value
exclude-moduleExclude a module specified in the value
exclude-classExclude a class specified in the value
exclude-methodExclude a method specified in the value
include-packageInclude a package specified in the value
include-moduleInclude a module specified in the value
include-classInclude a class specified in the value
include-methodInclude a method specified in the value

LogFlushMode:   Specifies the log flush mode.

Use this property to set the log flush mode. The following values are defined:

noneNo flush (caching only)
immediateImmediate flush (real-time logging)
maxcountFlush cached entries upon reaching LogMaxEventCount entries in the cache.

LogLevel:   Specifies the debug log level.

Use this property to provide the desired debug log level.

Supported values are:

noneNone (by default)
fatalSevere errors that cause premature termination.
errorOther runtime errors or unexpected conditions.
warningUse of deprecated APIs, poor use of API, 'almost' errors, other runtime situations that are undesirable or unexpected, but not necessarily "wrong".
infoInteresting runtime events (startup/shutdown).
debugDetailed information on flow of through the system.
traceMore detailed information.

LogMaxEventCount:   Specifies the maximum number of events to cache before further action is taken.

Use this property to specify the log event number threshold. This threshold may have different effects, depending on the rotation setting and/or the flush mode.

The default value of this setting is 100.

LogRotationMode:   Specifies the log rotation mode.

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

noneNo rotation
deleteolderDelete older entries from the cache upon reaching LogMaxEventCount
keepolderKeep 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.

StaticDNS:   Specifies whether static DNS rules should be used.

Set this property to enable or disable static DNS rules for the class. Works only if UseOwnDNSResolver is set to true.

Supported values are:

noneNo static DNS rules (default)
localLocal static DNS rules
globalGlobal 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 class) 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 devided 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 class is set to "local", the property returns/restores the rules from/to the internal storage of the class. If StaticDNS of the class 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 chached 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 classes.

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).

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.

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.
