Port Property (DTLSServer Component)

Specifies the port number to listen for connections on.

Syntax

property Port: Integer read get_Port write set_Port;

Default Value

Remarks

Use this property to specify the port number to listen to connections on. Standard port numbers are 80 for an HTTP server, and 443 for an HTTPS server.

Alternatively, you may specify the acceptable range of listening ports via PortRangeFrom and PortRangeTo properties. In this case the port will be allocated within the requested range by the operating system, and reported in BoundPort.

PortRangeFrom Property (DTLSServer Component)

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

Syntax

property PortRangeFrom: Integer read get_PortRangeFrom write set_PortRangeFrom;

Default Value

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 (DTLSServer Component)

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

Syntax

property PortRangeTo: Integer read get_PortRangeTo write set_PortRangeTo;

Default Value

Remarks

Use this property to specify the upper 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.

SocketSettings Property (DTLSServer Component)

Manages network connection settings.

Syntax

property SocketSettings: TsbxSocketSettings read get_SocketSettings;

Remarks

Use this property to tune up network connection parameters.

This property is read-only.

The server's TLS certificates.

Syntax

property TLSServerChain: TsbxCertificateList read get_TLSServerChain write set_TLSServerChain;

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.

TLSSettings Property (DTLSServer Component)

Manages TLS layer settings.

Syntax

property TLSSettings: TsbxTLSSettings read get_TLSSettings;

Cleanup Method (DTLSServer Component)

Cleans up the server environment by purging expired sessions and cleaning caches.

Syntax

procedure Cleanup();

Remarks

Call this method while the server is active to clean up the environment allocated for the server by releasing unused resources and cleaning caches.

Config Method (DTLSServer Component)

Sets or retrieves a configuration setting.

Syntax

function Config(ConfigurationString: String): String;

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 (DTLSServer Component)

Performs an additional action.

Syntax

function DoAction(ActionID: String; ActionParams: String): String;

Remarks

DoAction is a generic method available in every component. 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.

DropClient Method (DTLSServer Component)

Terminates a client connection.

Syntax

procedure DropClient(ConnectionId: Int64; Forced: Boolean);

Remarks

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

ExportKeyMaterial Method (DTLSServer Component)

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

Syntax

procedure ExportKeyMaterial(ConnectionID: Int64; Lbl: String; Context: TBytes; Len: Integer);

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 (DTLSServer Component)

Subscribe to Connect event to be notified of every connection that has been set up.

Connect Event (DTLSServer Component)

Reports a new 'connection'.

Syntax

type TConnectEvent = procedure (
  Sender: TObject;
  ConnectionID: Int64;
  const RemoteAddress: String;
  RemotePort: Integer
) of Object;

property OnConnect: TConnectEvent read FOnConnect write FOnConnect;

Remarks

The component fires this event to report that a datagram from a new source has been received. When using DTLS, this may typically be thought of as a request for a new datagram-driven secure channel.

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 (DTLSServer Component)

Supplies a data chunk received from a client.

Syntax

type TDataEvent = procedure (
  Sender: TObject;
  ConnectionID: Int64;
  const Buffer: TBytes
) of Object;

ExternalSign Event (DTLSServer Component)

Handles remote or external signing initiated by the server protocol.

Syntax

type TExternalSignEvent = procedure (
  Sender: TObject;
  ConnectionID: Int64;
  const OperationId: String;
  const HashAlgorithm: String;
  const Pars: String;
  const Data: String;
  var SignedData: String
) of Object;

property OnExternalSign: TExternalSignEvent 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 (DTLSServer Component)

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

  const EventParam: String
) of Object;

property OnNotification: TNotificationEvent 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:


ListeningStarted	Notifies the application that the server has started listening for incoming connections.

TLSShutdown Event (DTLSServer Component)

Reports closure of a TLS session.

Syntax

type TTLSShutdownEvent = procedure (
  Sender: TObject;
  ConnectionID: Int64
) of Object;

property OnTLSShutdown: TTLSShutdownEvent read FOnTLSShutdown write FOnTLSShutdown;

Remarks

Certificate Type

Encapsulates an individual X.509 certificate.

Remarks

This type keeps and provides access to X.509 certificate details.

The following fields are available:

Fields

Bytes
TBytes (read-only)
Default Value: ""

Returns the raw certificate data in DER format.

CA
Boolean
Default Value: False

Indicates whether the certificate has a CA capability. For the certificate to be considered a CA, it must have its Basic Constraints extension set with the CA indicator enabled.

Set this property when generating a new certificate to have its Basic Constraints extension generated automatically.

CAKeyID
TBytes (read-only)
Default Value: ""

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 generates this setting automatically if enough information is available to it: for self-signed certificates, this value is copied from the SubjectKeyID setting, and for lower-level certificates, from the parent certificate's subject key ID extension.

CertType
TsbxCertTypes (read-only)
Default Value: 0

Returns the type of the entity contained in the Certificate object.

A Certificate object can contain two types of cryptographic objects: a ready-to-use X.509 certificate, or a certificate request ("an unsigned certificate"). Certificate requests can be upgraded to full certificates by signing them with a CA certificate.

Use the CertificateManager component to load or create new certificate and certificate requests objects.

CRLDistributionPoints
String
Default Value: ""

Contains a list of locations of CRL distribution points used to check this certificate's validity. The list is taken from the respective certificate extension.

Use this property when generating a certificate to provide a list of CRL endpoints that should be made part of the new certificate.

The endpoints are provided as a list of CRLF-separated URLs. Note that this differs from the behaviour used in earlier product versions, where the "|" character was used as the location separator.

Curve
String
Default Value: ""

Specifies the elliptic curve associated with the certificate's public key. This setting only applies to certificates containing EC keys.

Fingerprint
String (read-only)
Default Value: ""

Contains the fingerprint (a hash imprint) of this certificate.

While there is no formal standard defining what a fingerprint is, a SHA1 hash of the certificate's DER-encoded body is typically used.

FriendlyName
String (read-only)
Default Value: ""

Contains an associated alias (friendly name) of the certificate. The friendly name is not a property of a certificate: it is maintained by the certificate media rather than being included in its DER representation. Windows certificate stores are one example of media that does support friendly names.

Handle
Int64
Default Value: 0

Allows to get or set a 'handle', a unique identifier of the underlying property object. Use this property to assign objects of the same type in a quicker manner, without copying them fieldwise.

When you pass a handle of one object to another, the source object is copied to the destination rather than assigned. It is safe to get rid of the original object after such operation. pdfSigner.setSigningCertHandle(certMgr.getCertHandle());

HashAlgorithm
String
Default Value: ""

Provides means to set the hash algorithm to be used in the subsequent operation on the certificate (such as generation or key signing). It is not a property of a certificate; use SigAlgorithm to find out the hash algorithm that is part of the certificate signature.

Issuer
String (read-only)
Default Value: ""

The common name of the certificate issuer (CA), typically a company name. This is part of a larger set of credentials available via IssuerRDN.

IssuerRDN
String
Default Value: ""

A list of Property=Value pairs that uniquely identify the certificate issuer.

Example: /C=US/O=Nationwide CA/CN=Web Certification Authority

KeyAlgorithm
String
Default Value: "0"

Specifies the public key algorithm of this certificate.

Use the KeyBits, Curve, and PublicKeyBytes properties to get more details about the key the certificate contains.

KeyBits
Integer (read-only)
Default Value: 0

Returns the length of the public key in bits.

This value indicates the length of the principal cryptographic parameter of the key, such as the length of the RSA modulus or ECDSA field. The key data returned by the PublicKeyBytes or PrivateKeyBytes property would typically contain auxiliary values, and therefore be longer.

KeyFingerprint
String (read-only)
Default Value: ""

Returns a SHA1 fingerprint of the public key contained in the certificate.

Note that the key fingerprint is different from the certificate fingerprint accessible via the Fingerprint property. The key fingeprint uniquely identifies the public key, and so can be the same for multiple certificates containing the same key.

KeyUsage
Integer
Default Value: 0

Indicates the purposes of the key contained in the certificate, in the form of an OR'ed flag set.

This value is a bit mask of the following values:


ckuUnknown	`0x00000`	Unknown key usage
ckuDigitalSignature	`0x00001`	Digital signature
ckuNonRepudiation	`0x00002`	Non-repudiation
ckuKeyEncipherment	`0x00004`	Key encipherment
ckuDataEncipherment	`0x00008`	Data encipherment
ckuKeyAgreement	`0x00010`	Key agreement
ckuKeyCertSign	`0x00020`	Certificate signing
ckuCRLSign	`0x00040`	Revocation signing
ckuEncipherOnly	`0x00080`	Encipher only
ckuDecipherOnly	`0x00100`	Decipher only
ckuServerAuthentication	`0x00200`	Server authentication
ckuClientAuthentication	`0x00400`	Client authentication
ckuCodeSigning	`0x00800`	Code signing
ckuEmailProtection	`0x01000`	Email protection
ckuTimeStamping	`0x02000`	Timestamping
ckuOCSPSigning	`0x04000`	OCSP signing
ckuSmartCardLogon	`0x08000`	Smartcard logon
ckuKeyPurposeClientAuth	`0x10000`	Kerberos - client authentication
ckuKeyPurposeKDC	`0x20000`	Kerberos - KDC

Set this property before generating the certificate to propagate the key usage flags to the new certificate.

KeyValid
Boolean (read-only)
Default Value: False

Returns True if the certificate's key is cryptographically valid, and False otherwise.

OCSPLocations
String
Default Value: ""

Locations of OCSP services that can be used to check this certificate's validity in real time, as recorded by the CA.

Set this property before calling the certificate manager's Generate method to propagate it to the new certificate.

The OCSP locations are provided as a list of CRLF-separated URLs. Note that this differs from the behaviour used in earlier product versions, where the "|" character was used as the location separator.

OCSPNoCheck
Boolean
Default Value: False

Accessor to the value of the certificate's ocsp-no-check extension.

Origin
Integer (read-only)
Default Value: 0

Returns the location that the certificate was taken or loaded from.

PolicyIDs
String
Default Value: ""

Contains identifiers (OIDs) of the applicable certificate policies.

The Certificate Policies extension identifies a sequence of policies under which the certificate has been issued, and which regulate its usage.

Set this property when generating a certificate to propagate the policies information to the new certificate.

The policies are provided as a list of CRLF-separated entries. Note that this differs from the behaviour used in earlier product versions, where the "|" character was used as the policy element separator.

PrivateKeyBytes
TBytes (read-only)
Default Value: ""

Returns the certificate's private key in DER-encoded format. It is normal for this property to be empty if the private key is non-exportable, which, for example, is typical for certificates originating from hardware security devices.

PrivateKeyExists
Boolean (read-only)
Default Value: False

Indicates whether the certificate has a usable private key associated with it. If it is set to True, the certificate can be used for private key operations, such as signing or decryption.

This property is independent from PrivateKeyBytes, and can be set to True even if the former is empty. This would imply that the private key is non-exportable, but still can be used for cryptographic operations.

PrivateKeyExtractable
Boolean (read-only)
Default Value: False

Indicates whether the private key is extractable (exportable).

PublicKeyBytes
TBytes (read-only)
Default Value: ""

Contains the certificate's public key in DER format.

This typically would contain an ASN.1-encoded public key value. The exact format depends on the type of the public key contained in the certificate.

Qualified
Boolean (read-only)
Default Value: False

Indicates whether the certificate is qualified.

This property is set to True if the certificate is confirmed by a Trusted List to be qualified.

QualifiedStatements
TsbxQualifiedStatementsTypes
Default Value: 0

Returns a simplified qualified status of the certificate.

Qualifiers
String (read-only)
Default Value: ""

A list of qualifiers.

Contains a comma-separated list of qualifier aliases for the certificate, for example QCP-n-qscd,QCWithSSCD.

SelfSigned
Boolean (read-only)
Default Value: False

Indicates whether the certificate is self-signed (root) or signed by an external CA.

SerialNumber
TBytes
Default Value: ""

Returns the certificate's serial number.

The serial number is a binary string that uniquely identifies a certificate among others issued by the same CA. According to the X.509 standard, the (issuer, serial number) pair should be globally unique to facilitate chain building.

SigAlgorithm
String (read-only)
Default Value: ""

Indicates the algorithm that was used by the CA to sign this certificate.

A signature algorithm typically combines hash and public key algorithms together, such as sha256WithRSAEncryption or ecdsa-with-SHA256.

Source
TsbxPKISources (read-only)
Default Value: 0

Returns the source (location or disposition) of a cryptographic primitive entity, such as a certificate, CRL, or OCSP response.

Subject
String (read-only)
Default Value: ""

The common name of the certificate holder, typically an individual's name, a URL, an e-mail address, or a company name. This is part of a larger set of credentials available via SubjectRDN.

SubjectAlternativeName
String
Default Value: ""

Returns or sets the value of the Subject Alternative Name extension of the certificate.

Subject alternative names are used to provide additional names that are impractical to store in the main SubjectRDN field. For example, it is often used to store all the domain names that a TLS certificate is authorized to protect.

The alternative names are provided as a list of CRLF-separated entries. Note that this differs from the behaviour used in earlier product versions, where the "|" character was used as the element separator.

SubjectKeyID
TBytes
Default Value: ""

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 SubjectKeyID and CAKeyID properties of self-signed certificates typically contain identical values, as in that specific case, the issuer and the subject are the same entity.

SubjectRDN
String
Default Value: ""

A list of Property=Value pairs that uniquely identify the certificate holder (subject).

Depending on the purpose of the certificate and the policies of the CA that issued it, the values included in the subject record may differ drastically and contain business or personal names, web URLs, email addresses, and other data.

Example: /C=US/O=Oranges and Apples, Inc./OU=Accounts Receivable/1.2.3.4.5=Value with unknown OID/CN=Margaret Watkins.

Valid
Boolean (read-only)
Default Value: False

Indicates whether or not the signature over the certificate or the request is valid and matches the public key contained in the CA certificate/request.

ValidFrom
String
Default Value: ""

The time point at which the certificate becomes valid, in UTC.

ValidTo
String
Default Value: ""

The time point at which the certificate expires, in UTC.

Constructors

constructor Create();

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.

The following fields are available:

AsyncDocumentID

CustomParams

Data

ExternalHashCalculation

Fields

AsyncDocumentID
String
Default Value: ""

Specifies an optional document ID for SignAsyncBegin() and SignAsyncEnd() calls.

Use this property when working with multi-signature DCAuth requests and responses to uniquely identify documents signed within a larger batch. On the completion stage, this value helps the signing component identify the correct signature in the returned batch of responses.

If using batched requests, make sure to set this property to the same value on both the pre-signing (SignAsyncBegin) and completion (SignAsyncEnd) stages.

CustomParams
String
Default Value: ""

Custom parameters to be passed to the signing service (uninterpreted).

Data
String
Default Value: ""

Additional data to be included in the async state and mirrored back by the requestor.

ExternalHashCalculation
Boolean
Default Value: False

Specifies whether the message hash is to be calculated at the external endpoint. Please note that this mode is not supported by the DCAuth component.

If set to true, the component will pass a few kilobytes of to-be-signed data from the document to the OnExternalSign event. This only applies when SignExternal() is called.

HashAlgorithm
String
Default Value: "SHA256"

Specifies the request's signature hash algorithm.

KeyID
String
Default Value: ""

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 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";

KeySecret
String
Default Value: ""

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 KeyID topic.

ClientAuth
TsbxClientAuthTypes
Default Value: 0

Enables or disables certificate-based client authentication.

Set this property to true to tune up the client authentication type:


ccatNoAuth	`0`
ccatRequestCert	`1`
ccatRequireCert	`2`

ECCurves
String
Default Value: ""

Defines the elliptic curves to enable.

Extensions
String
Default Value: ""

Provides access to TLS extensions.

ForceResumeIfDestinationChanges
Boolean
Default Value: False

Whether to force TLS session resumption when the destination address changes.

PreSharedIdentity
String
Default Value: ""

Defines the identity used when the PSK (Pre-Shared Key) key-exchange mechanism is negotiated.

PreSharedKey
String
Default Value: ""

Contains the pre-shared key for the PSK (Pre-Shared Key) key-exchange mechanism, encoded with base16.

PreSharedKeyCiphersuite
String
Default Value: ""

Defines the ciphersuite used for PSK (Pre-Shared Key) negotiation.

RenegotiationAttackPreventionMode
TsbxRenegotiationAttackPreventionModes
Default Value: 2

Selects the renegotiation attack prevention mechanism.

The following options are available:


crapmCompatible	`0`	TLS 1.0 and 1.1 compatibility mode (renegotiation indication extension is disabled).
crapmStrict	`1`	Renegotiation attack prevention is enabled and enforced.
crapmAuto	`2`	Automatically choose whether to enable or disable renegotiation attack prevention.

RevocationCheck
TsbxRevocationCheckKinds
Default Value: 1

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.

Constructors

constructor Create();

Creates a new TLSSettings object.

Config Settings (DTLSServer Component)

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

DTLSServer Config Settings

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.

ClientAuth: Enables or disables certificate-based client authentication.

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


0		No client authentication (the default setting)
1		Request certificates. The server will ask connecting clients for their certificates. Non-authenticated client connections will be accepted anyway.
2		Require 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.

DatagramSize: Specifies maximum size of the datagram.

Use this property to get or set maximum size of the datagram. Data pieces larger than DatagramSize will be split into several smaller datagrams with lengths smaller (or equal) to the DatagramSize.

DualStack: Allows the use of ip4 and ip6 simultaneously.

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

MaxDataSize: Specifies maximum size of the packet which will not be divided into smaller ones.

Use this read-only property to get the maximum size of the data piece which will not be divided into smaller ones. The value of this property is smaller or equal to the DatagramSize.

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.

RetransmissionInterval: Specifies value of the retransmission interval.

Use this property to specify the period of time in milliseconds, after which the client will repeat sending. Set this property to 0 to disable the retransmission timer. Defaul value is 1000 (i.e. 1 second).

SocketHandle: Returns the socket handle of the connected component.

Read this config property to get the socket handle of the active socket. In servers, either pin the specific client connection before checking this property, or pass the connection ID as an index (SocketHandle[connId]).

SocketHandle[i]: Returns the internal socket handle.

Use this property to read the socket handle of the connection number i.

SplitLongData: Specifies whether to split long datagrams into smaller ones.

If this prperty is set to True, datagrams larger than MaxDataSize will be split into smaller ones. Default value is True.

SrtpMasterKeyLen: The SRTP master key length.

Gets or sets the length, in bytes, of the SRTP master key. The default value is 16.

SrtpMasterSaltLen: The SRTP master salt length.

Gets or sets the length of the SRTP master salt, in bytes. The default setting is 14.

TLSExtensions: TBD.

TBD

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 component.

Supported values are:


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

Cookies: Gets or sets local cookies for the component.

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

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

HardwareCryptoUsePolicy: The hardware crypto usage policy.

This global setting controls the hardware cryptography usage policy: auto, enable, or disable.

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 components.

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.

none		No flush (caching only)
immediate		Immediate flush (real-time logging)
maxcount		Flush 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:


none		None (by default)
fatal		Severe errors that cause premature termination.
error		Other runtime errors or unexpected conditions.
warning		Use of deprecated APIs, poor use of API, 'almost' errors, other runtime situations that are undesirable or unexpected, but not necessarily "wrong".
info		Interesting runtime events (startup/shutdown).
debug		Detailed information on flow of through the system.
trace		More 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:


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): 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: 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 component. 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 component) 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 component is set to "local", the property returns/restores the rules from/to the internal storage of the component. If StaticDNS of the component 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 components.

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: 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: Config("XMLRDNDescriptorName[2.5.4.5]=SERIALNUMBER");

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