QByteArray GetTLSServerCertBytes(int iTLSServerCertIndex);

qint64 GetTLSServerCertHandle(int iTLSServerCertIndex);
int SetTLSServerCertHandle(int iTLSServerCertIndex, qint64 lTLSServerCertHandle);

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.

Data Type

String

BroadcastData Method (DTLSServer Class)

Broadcasts data to all connections.

Syntax

ANSI (Cross Platform)
int BroadcastData(int64 lConnectionID, const char* lpData, int lenData);

Unicode (Windows)
INT BroadcastData(LONG64 lConnectionID, LPCSTR lpData, INT lenData);

int secureblackbox_dtlsserver_broadcastdata(void* lpObj, int64 lConnectionID, const char* lpData, int lenData);

int BroadcastData(qint64 lConnectionID, QByteArray qbaData);

Remarks

Call this method to send Data to all active client connections except for ConnectionID. Set ConnectionID to -1 to broadcast to all connections.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

BroadcastText Method (DTLSServer Class)

Broadcasts a text string to all connections.

Syntax

ANSI (Cross Platform)
int BroadcastText(int64 lConnectionId, const char* lpszText);

Unicode (Windows)
INT BroadcastText(LONG64 lConnectionId, LPCWSTR lpszText);

int secureblackbox_dtlsserver_broadcasttext(void* lpObj, int64 lConnectionId, const char* lpszText);

int BroadcastText(qint64 lConnectionId, const QString& qsText);

Error Handling (C++)

Config Method (DTLSServer Class)

Sets or retrieves a configuration setting.

Syntax

ANSI (Cross Platform)
char* Config(const char* lpszConfigurationString);

Unicode (Windows)
LPWSTR Config(LPCWSTR lpszConfigurationString);

char* secureblackbox_dtlsserver_config(void* lpObj, const char* lpszConfigurationString);

QString Config(const QString& qsConfigurationString);

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.

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

DoAction Method (DTLSServer Class)

Performs an additional action.

Syntax

ANSI (Cross Platform)
char* DoAction(const char* lpszActionID, const char* lpszActionParams);

Unicode (Windows)
LPWSTR DoAction(LPCWSTR lpszActionID, LPCWSTR lpszActionParams);

char* secureblackbox_dtlsserver_doaction(void* lpObj, const char* lpszActionID, const char* lpszActionParams);

QString DoAction(const QString& qsActionID, const QString& qsActionParams);

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 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;....

Error Handling (C++)

DropClient Method (DTLSServer Class)

Syntax

ANSI (Cross Platform)
int DropClient(int64 lConnectionId, int bForced);

Unicode (Windows)
INT DropClient(LONG64 lConnectionId, BOOL bForced);

int secureblackbox_dtlsserver_dropclient(void* lpObj, int64 lConnectionId, int bForced);

Unicode (Windows)
INT ExportKeyMaterial(LONG64 lConnectionID, LPCWSTR lpszLbl, LPCSTR lpContext, INT lenContext, INT iLen);

int secureblackbox_dtlsserver_exportkeymaterial(void* lpObj, int64 lConnectionID, const char* lpszLbl, const char* lpContext, int lenContext, int iLen);

int ExportKeyMaterial(qint64 lConnectionID, const QString& qsLbl, QByteArray qbaContext, int iLen);

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.

Error Handling (C++)

ListClients Method (DTLSServer Class)

Enumerates the connected clients.

Syntax

  LPWSTR SignedData;
  INT reserved;
} DTLSServerExternalSignEventParams;

#define EID_DTLSSERVER_EXTERNALSIGN 6

virtual INT SECUREBLACKBOX_CALL FireExternalSign(LONG64 &lConnectionID, LPSTR &lpszOperationId, LPSTR &lpszHashAlgorithm, LPSTR &lpszPars, LPSTR &lpszData, LPSTR &lpszSignedData);

class DTLSServerExternalSignEventParams {

// To handle, connect one or more slots to this signal.
void ExternalSign(DTLSServerExternalSignEventParams *e);

// Or, subclass DTLSServer and override this emitter function.
virtual int FireExternalSign(DTLSServerExternalSignEventParams *e) {...}

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 class via the SignedData parameter.

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

The class 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 Class)

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

Syntax

ANSI (Cross Platform)
virtual int FireNotification(DTLSServerNotificationEventParams *e);

typedef struct {
  const char *EventID;
  const char *EventParam;
  int reserved;

  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void Notification(DTLSServerNotificationEventParams *e);

// Or, subclass DTLSServer and override this emitter function.
virtual int FireNotification(DTLSServerNotificationEventParams *e) {...}

Remarks

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

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


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

void TLSEstablished(DTLSServerTLSEstablishedEventParams *e);

// Or, subclass DTLSServer and override this emitter function.
virtual int FireTLSEstablished(DTLSServerTLSEstablishedEventParams *e) {...}

Remarks

Subscribe to this event to be notified about the setup of a TLS connection by a connected client.

TLSHandshake Event (DTLSServer Class)

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

Syntax

ANSI (Cross Platform)
virtual int FireTLSHandshake(DTLSServerTLSHandshakeEventParams *e);

typedef struct {
  int64 ConnectionID;
  const char *ServerName;
  int Abort;
  int reserved;
} DTLSServerTLSHandshakeEventParams;


Unicode (Windows)
virtual INT FireTLSHandshake(DTLSServerTLSHandshakeEventParams *e);

typedef struct {
  LONG64 ConnectionID;
  LPCWSTR ServerName;
  BOOL Abort;
  INT reserved;
} DTLSServerTLSHandshakeEventParams;

#define EID_DTLSSERVER_TLSHANDSHAKE 11

virtual INT SECUREBLACKBOX_CALL FireTLSHandshake(LONG64 &lConnectionID, LPSTR &lpszServerName, BOOL &bAbort);

class DTLSServerTLSHandshakeEventParams {
public:
  qint64 ConnectionID();

  const QString &ServerName();

  bool Abort();
  void SetAbort(bool bAbort);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void TLSHandshake(DTLSServerTLSHandshakeEventParams *e);

// Or, subclass DTLSServer and override this emitter function.
virtual int FireTLSHandshake(DTLSServerTLSHandshakeEventParams *e) {...}

Remarks

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

TLSPSK Event (DTLSServer Class)

Requests a pre-shared key for TLS-PSK.

Syntax

ANSI (Cross Platform)
virtual int FireTLSPSK(DTLSServerTLSPSKEventParams *e);

typedef struct {
  int64 ConnectionID;
  const char *Identity;
  char *PSK;
  char *Ciphersuite;
  int reserved;
} DTLSServerTLSPSKEventParams;


Unicode (Windows)
virtual INT FireTLSPSK(DTLSServerTLSPSKEventParams *e);

typedef struct {
  LONG64 ConnectionID;
  LPCWSTR Identity;
  LPWSTR PSK;
  LPWSTR Ciphersuite;
  INT reserved;
} DTLSServerTLSPSKEventParams;

#define EID_DTLSSERVER_TLSPSK 12

virtual INT SECUREBLACKBOX_CALL FireTLSPSK(LONG64 &lConnectionID, LPSTR &lpszIdentity, LPSTR &lpszPSK, LPSTR &lpszCiphersuite);

class DTLSServerTLSPSKEventParams {
public:
  qint64 ConnectionID();

  const QString &Identity();

  const QString &PSK();
  void SetPSK(const QString &qsPSK);

  const QString &Ciphersuite();
  void SetCiphersuite(const QString &qsCiphersuite);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void TLSPSK(DTLSServerTLSPSKEventParams *e);

// Or, subclass DTLSServer and override this emitter function.
virtual int FireTLSPSK(DTLSServerTLSPSKEventParams *e) {...}

Remarks

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 (DTLSServer Class)

Reports closure of a TLS session.

Syntax

ANSI (Cross Platform)
virtual int FireTLSShutdown(DTLSServerTLSShutdownEventParams *e);

typedef struct {
  int64 ConnectionID;
  int reserved;
} DTLSServerTLSShutdownEventParams;


Unicode (Windows)
virtual INT FireTLSShutdown(DTLSServerTLSShutdownEventParams *e);

typedef struct {
  LONG64 ConnectionID;
  INT reserved;
} DTLSServerTLSShutdownEventParams;

#define EID_DTLSSERVER_TLSSHUTDOWN 13

virtual INT SECUREBLACKBOX_CALL FireTLSShutdown(LONG64 &lConnectionID);

class DTLSServerTLSShutdownEventParams {
public:
  qint64 ConnectionID();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void TLSShutdown(DTLSServerTLSShutdownEventParams *e);

// Or, subclass DTLSServer and override this emitter function.
virtual int FireTLSShutdown(DTLSServerTLSShutdownEventParams *e) {...}

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

Encapsulates an individual X.509 certificate.

Syntax

SecureBlackboxCertificate (declared in secureblackbox.h)

Remarks

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

The following fields are available:

Fields

Bytes
char* (read-only)
Default Value:

Returns the raw certificate data in DER format.

CA
int
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 field when generating a new certificate to have its Basic Constraints extension generated automatically.

CAKeyID
char* (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
int (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 class to load or create new certificate and certificate requests objects.

CRLDistributionPoints
char*
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 field 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
char*
Default Value: ""

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

Fingerprint
char* (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
char* (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
char*
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
char* (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
char*
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
char*
Default Value: "0"

Specifies the public key algorithm of this certificate.

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

KeyBits
int (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 field would typically contain auxiliary values, and therefore be longer.

KeyFingerprint
char* (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 field. The key fingeprint uniquely identifies the public key, and so can be the same for multiple certificates containing the same key.

KeyUsage
int
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

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

ckuKeyPurposeKDC	`0x20000`	Kerberos - KDC

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

KeyValid
int (read-only)
Default Value: FALSE

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

OCSPLocations
char*
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 field 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
int
Default Value: FALSE

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

Origin
int (read-only)
Default Value: 0

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

PolicyIDs
char*
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 field 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
char* (read-only)
Default Value:

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

PrivateKeyExists
int (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 field 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
int (read-only)
Default Value: FALSE

Indicates whether the private key is extractable (exportable).

PublicKeyBytes
char* (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
int (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
int
Default Value: 0

Returns a simplified qualified status of the certificate.

Qualifiers
char* (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
int (read-only)
Default Value: FALSE

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

SerialNumber
char*
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
char* (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
int (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
char* (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
char*
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
char*
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 fields of self-signed certificates typically contain identical values, as in that specific case, the issuer and the subject are the same entity.

SubjectRDN
char*
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
int (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
char*
Default Value: ""

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

ValidTo
char*
Default Value: ""

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

Constructors

Creates a new object with default field values.

ExternalCrypto Type

Specifies the parameters of external cryptographic calls.

Syntax

SecureBlackboxExternalCrypto (declared in secureblackbox.h)

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
char*
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
char*
Default Value: ""

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

Data
char*
Default Value: ""

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

ExternalHashCalculation
int
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 class.

If set to true, the class 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
char*
Default Value: "SHA256"

Specifies the request's signature hash algorithm.

SB_HASH_ALGORITHM_SHAKE_256_LEN	`SHAKE_256_LEN`

KeyID
char*
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
char*
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
int
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
char*
Default Value: ""

Defines the elliptic curves to enable.

Extensions
char*
Default Value: ""

Provides access to TLS extensions.

ForceResumeIfDestinationChanges
int
Default Value: FALSE

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

PreSharedIdentity
char*
Default Value: ""

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

PreSharedKey
char*
Default Value: ""

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

PreSharedKeyCiphersuite
char*
Default Value: ""

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

RenegotiationAttackPreventionMode
int
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
int
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.

SecureBlackboxList Type

Syntax

SecureBlackboxList<T> (declared in secureblackbox.h)

Remarks

SecureBlackboxList is a generic class that is used to hold a collection of objects of type T, where T is one of the custom types supported by the DTLSServer class.

Methods

GetCount	This method returns the current size of the collection. int GetCount() {}
SetCount	This method sets the size of the collection. This method returns `0` if setting the size was successful; or `-1` if the collection is `ReadOnly`. When adding additional objects to a collection call this method to specify the new size. Increasing the size of the collection preserves existing objects in the collection. int SetCount(int count) {}
Get	This method gets the item at the specified position. The `index` parameter specifies the index of the item in the collection. This method returns `NULL` if an invalid `index` is specified. T* Get(int index) {}
Set	This method sets the item at the specified position. The `index` parameter specifies the index of the item in the collection that is being set. This method returns `-1` if an invalid `index` is specified. Note: Objects created using the `new` operator must be freed using the `delete` operator; they will not be automatically freed by the class. T* Set(int index, T* value) {}

Config Settings (DTLSServer 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.

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 class.

Supported values are:


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

Cookies: Gets or sets local cookies for the class.

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.

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

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.

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.

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 class. 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 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).

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.

Trappable Errors (DTLSServer Class)

Error Handling (C++)

Call the GetLastErrorCode() method to obtain the last called method's result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. Known error codes are listed below. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.
