SMTPClient Class

Properties Methods Events Config Settings Errors

The SMTPClient class provides client-side functionality for SMTP (Simple Mail Transfer Protocol).

Syntax

SMTPClient

Remarks

Use this component to send e-mails from your application.

You can connect to an SMTP server using either username/password or with an access token. // Connect using username/password SMTPClient client = new SMTPClient(); client.Username = "user"; client.Password = "password"; client.Connect("mail.domain.com", 465); client.SendFile("path\\message.eml"); client.Disconnect(); // Connect using an access token (note that the username should be the same as the one used to obtain the access token) SMTPClient client = new SMTPClient(); client.Username = "user"; client.AccessToken = access_token; client.Connect("smtp.gmail.com", 587); client.SendBytes(buffer); client.Disconnect(); // To send messages without authentication, switch off ForceLogin config property SMTPClient client = new SMTPClient(); client.Config("ForceLogin=false"); client.Connect("smtp.myisp.net", 25); client.SendBytes(buffer); client.Disconnect();

Use Command and CommandReply events to get a session log. SMTPClient client = new SMTPClient(); client.OnCommand += delegate (Object sender, SMTPClientCommandEventArgs e) { Console.WriteLine($"C: {e.Cmd}"); }; client.OnCommandReply += delegate (Object sender, SMTPClientCommandReplyEventArgs e) { Console.WriteLine($"S: {e.Reply}"); };

Use this property to supply a list of additional certificates that might be needed for chain validation. An example of a scenario where you might want to do that is when intermediary CA certificates are absent from the standard system locations (or when there are no standard system locations), and therefore should be supplied to the class manually.

The purpose of the certificates to be added to this collection is roughly equivalent to that of the Intermediate Certification Authorities system store in Windows.

Do not add trust anchors or root certificates to this collection: add them to TrustedCertificates instead.

TrustedCertificates Property (SMTPClient Class)

A list of trusted certificates for chain validation.

Syntax

SecureBlackboxList<SecureBlackboxCertificate>* GetTrustedCertificates();
int SetTrustedCertificates(SecureBlackboxList<SecureBlackboxCertificate>* val);

int secureblackbox_smtpclient_gettrustedcertcount(void* lpObj);
int secureblackbox_smtpclient_settrustedcertcount(void* lpObj, int iTrustedCertCount);

QByteArray GetTrustedCertBytes(int iTrustedCertIndex);

qint64 GetTrustedCertHandle(int iTrustedCertIndex);
int SetTrustedCertHandle(int iTrustedCertIndex, qint64 lTrustedCertHandle);

Remarks

Use this property to supply a list of trusted certificates that might be needed for chain validation. An example of a scenario where you might want to do that is when root CA certificates are absent from the standard system locations (or when there are no standard system locations), and therefore should be supplied to the component manually.

The purpose of this certificate collection is largely the same as that of the Windows Trusted Root Certification Authorities system store.

Use this property with extreme care as it directly affects chain verifiability; a wrong certificate added to the trusted list may result in bad chains being accepted, and forfeited signatures being recognized as genuine. Only add certificates that originate from the parties that you know and trust.

This property is not available at design time.

Data Type

Username Property (SMTPClient Class)

The authentication username.

Syntax

ANSI (Cross Platform)
char* GetUsername();

Config Method (SMTPClient Class)

Sets or retrieves a configuration setting.

Syntax

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

Unicode (Windows)
LPWSTR Config(LPCWSTR lpszConfigurationString);

char* secureblackbox_smtpclient_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.

int Connect(const char* lpszAddress, int iPort);

Unicode (Windows)
INT Connect(LPCWSTR lpszAddress, INT iPort);

int secureblackbox_smtpclient_connect(void* lpObj, const char* lpszAddress, int iPort);

int Connect(const QString& qsAddress, int iPort);

Remarks

Use this method to establish a connection to the SMTP server at Address and Port.

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.)

Disconnect Method (SMTPClient Class)

Closes connection to the SMTP server.

Syntax

ANSI (Cross Platform)
int Disconnect();

Unicode (Windows)
INT Disconnect();

int secureblackbox_smtpclient_disconnect(void* lpObj);

char* secureblackbox_smtpclient_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++)

virtual int FireAuthFailed(SMTPClientAuthFailedEventParams *e);

typedef struct {
  const char *Auth;
  int ErrorCode;
  const char *ErrorMessage;
  const char *ServerReply;
  int TryAgain;
  int reserved;
} SMTPClientAuthFailedEventParams;


Unicode (Windows)
virtual INT FireAuthFailed(SMTPClientAuthFailedEventParams *e);

typedef struct {
  LPCWSTR Auth;
  INT ErrorCode;
  LPCWSTR ErrorMessage;
  LPCWSTR ServerReply;
  BOOL TryAgain;
  INT reserved;
} SMTPClientAuthFailedEventParams;

#define EID_SMTPCLIENT_AUTHFAILED 1

virtual INT SECUREBLACKBOX_CALL FireAuthFailed(LPSTR &lpszAuth, INT &iErrorCode, LPSTR &lpszErrorMessage, LPSTR &lpszServerReply, BOOL &bTryAgain);

class SMTPClientAuthFailedEventParams {
public:
  const QString &Auth();

  int ErrorCode();

  const QString &ErrorMessage();

  const QString &ServerReply();

  bool TryAgain();
  void SetTryAgain(bool bTryAgain);

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

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

// Or, subclass SMTPClient and override this emitter function.
virtual int FireAuthFailed(SMTPClientAuthFailedEventParams *e) {...}

Remarks

The class fires this event when an authentication attempt has failed for some reason.

Auth reports the authentication method that has failed. You can adjust the Authentications config property to try another method.

ErrorCode contains an error code, and ErrorMessage contains an error message.

ServerReply provides the error info reported by the server. This info depends on the transport protocol and on the authentication method.

Set the TryAgain parameter to true if the class should try to authenticate again. If the parameter remains false, the authentication will fail with an exception.

AuthStart Event (SMTPClient Class)

Fires when the authentication is about to be started.

Syntax

ANSI (Cross Platform)
virtual int FireAuthStart(SMTPClientAuthStartEventParams *e);

typedef struct {
  const char *UsableAuths;
  int reserved;
} SMTPClientAuthStartEventParams;


Unicode (Windows)

  void SetEventRetVal(int iRetVal);
};

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

// Or, subclass SMTPClient and override this emitter function.
virtual int FireAuthStart(SMTPClientAuthStartEventParams *e) {...}

Remarks

The class fires this event when it has established the TCP connection and is ready to proceed to the user authentication step.

The UsableAuths parameter contains a comma-separated list of the authentication methods supported by both, the client and the server.

In this event handler it's possible to update the method list in the Authentications config property according to the provided list of usable methods. The full list of the authentication methods supported by the server is available in ServerInfo.SupportedAuths.

AuthSucceeded Event (SMTPClient Class)

Fires when the authentication has succeeded.

ErrorCode contains an error code and Description contains a textual description of the error.

ExternalSign Event (SMTPClient Class)

Handles remote or external signing initiated by the SignExternal method or other source.

Syntax

ANSI (Cross Platform)
virtual int FireExternalSign(SMTPClientExternalSignEventParams *e);

typedef struct {
  const char *OperationId;
  const char *HashAlgorithm;
  const char *Pars;
  const char *Data;
  char *SignedData;
  int reserved;
} SMTPClientExternalSignEventParams;


Unicode (Windows)

typedef struct {
  LPCWSTR OperationId;
  LPCWSTR HashAlgorithm;
  LPCWSTR Pars;
  LPCWSTR Data;
  LPWSTR SignedData;
  INT reserved;
} SMTPClientExternalSignEventParams;

#define EID_SMTPCLIENT_EXTERNALSIGN 8

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

class SMTPClientExternalSignEventParams {
public:
  const QString &OperationId();

  const QString &HashAlgorithm();

  const QString &Pars();

  const QString &Data();

  const QString &SignedData();
  void SetSignedData(const QString &qsSignedData);

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

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

// Or, subclass SMTPClient and override this emitter function.
virtual int FireExternalSign(SMTPClientExternalSignEventParams *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 (SMTPClient Class)

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

Syntax

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

typedef struct {

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

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

// Or, subclass SMTPClient and override this emitter function.
virtual int FireNotification(SMTPClientNotificationEventParams *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:


TLSExtensions.CertificateStatus	TBD
TLSExtensions.PreSharedIdentityHint	TBD

Progress Event (SMTPClient Class)

};

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

// Or, subclass SMTPClient and override this emitter function.
virtual int FireProgress(SMTPClientProgressEventParams *e) {...}

Remarks

The class fires this event repeatedly to report the progress of the data transfer operation.

TLSCertNeeded Event (SMTPClient Class)

Fires when a remote TLS party requests a client certificate.

Syntax

ANSI (Cross Platform)
virtual int FireTLSCertNeeded(SMTPClientTLSCertNeededEventParams *e);

typedef struct {
  const char *Host;
  const char *CANames;
  int reserved;
} SMTPClientTLSCertNeededEventParams;


Unicode (Windows)
virtual INT FireTLSCertNeeded(SMTPClientTLSCertNeededEventParams *e);

typedef struct {
  LPCWSTR Host;
  LPCWSTR CANames;
  INT reserved;
} SMTPClientTLSCertNeededEventParams;

#define EID_SMTPCLIENT_TLSCERTNEEDED 11

virtual INT SECUREBLACKBOX_CALL FireTLSCertNeeded(LPSTR &lpszHost, LPSTR &lpszCANames);

class SMTPClientTLSCertNeededEventParams {
public:
  const QString &Host();

  const QString &CANames();

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

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

// Or, subclass SMTPClient and override this emitter function.
virtual int FireTLSCertNeeded(SMTPClientTLSCertNeededEventParams *e) {...}

Remarks

This event fires to notify the implementation that a remote TLS server has requested a client certificate. The Host parameter identifies the host that makes a request, and the CANames parameter (optional, according to the TLS spec) advises on the accepted issuing CAs.

Use the TLSClientChain property in response to this event to provide the requested certificate. Please make sure the client certificate includes the associated private key. Note that you may set the certificates before the connection without waiting for this event to fire.

This event is preceded by the TLSHandshake event for the given host and, if the certificate was accepted, succeeded by the TLSEstablished event.

TLSCertValidate Event (SMTPClient Class)

This event is fired upon receipt of the TLS server's certificate, allowing the user to control its acceptance.

Syntax

ANSI (Cross Platform)
virtual int FireTLSCertValidate(SMTPClientTLSCertValidateEventParams *e);

typedef struct {
  const char *ServerHost;
  const char *ServerIP;
  int Accept;
  int reserved;
} SMTPClientTLSCertValidateEventParams;


Unicode (Windows)
virtual INT FireTLSCertValidate(SMTPClientTLSCertValidateEventParams *e);

typedef struct {
  LPCWSTR ServerHost;
  LPCWSTR ServerIP;
  BOOL Accept;
  INT reserved;

#define EID_SMTPCLIENT_TLSCERTVALIDATE 12

virtual INT SECUREBLACKBOX_CALL FireTLSCertValidate(LPSTR &lpszServerHost, LPSTR &lpszServerIP, BOOL &bAccept);

class SMTPClientTLSCertValidateEventParams {
public:
  const QString &ServerHost();

  const QString &ServerIP();

  bool Accept();
  void SetAccept(bool bAccept);

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

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

// Or, subclass SMTPClient and override this emitter function.
virtual int FireTLSCertValidate(SMTPClientTLSCertValidateEventParams *e) {...}

Remarks

This event is fired during a TLS handshake. Use the TLSServerChain property to access the certificate chain. In general, classes may contact a number of TLS endpoints during their work, depending on their configuration.

Accept is assigned in accordance with the outcome of the internal validation check performed by the class, and can be adjusted if needed.

TLSEstablished Event (SMTPClient Class)

Fires when a TLS handshake with Host successfully completes.

Syntax

ANSI (Cross Platform)
virtual int FireTLSEstablished(SMTPClientTLSEstablishedEventParams *e);

typedef struct {
  const char *Host;
  const char *Version;
  const char *Ciphersuite;
  const char *ConnectionId;
  int lenConnectionId;
  int Abort;
  int reserved;
} SMTPClientTLSEstablishedEventParams;


Unicode (Windows)
virtual INT FireTLSEstablished(SMTPClientTLSEstablishedEventParams *e);

typedef struct {
  LPCWSTR Host;
  LPCWSTR Version;
  LPCWSTR Ciphersuite;
  LPCSTR ConnectionId;
  INT lenConnectionId;
  BOOL Abort;
  INT reserved;
} SMTPClientTLSEstablishedEventParams;

#define EID_SMTPCLIENT_TLSESTABLISHED 13

virtual INT SECUREBLACKBOX_CALL FireTLSEstablished(LPSTR &lpszHost, LPSTR &lpszVersion, LPSTR &lpszCiphersuite, LPSTR &lpConnectionId, INT &lenConnectionId, BOOL &bAbort);

class SMTPClientTLSEstablishedEventParams {
public:
  const QString &Host();

  const QString &Version();

  const QString &Ciphersuite();

  const QByteArray &ConnectionId();

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

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

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

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

Remarks

The class uses this event to notify the application about a successful completion of a TLS handshake.

The Version, Ciphersuite, and ConnectionId parameters indicate the security parameters of the new connection. Use the Abort parameter if you need to terminate the connection at this stage.

TLSHandshake Event (SMTPClient Class)

Fires when a new TLS handshake is initiated, before the handshake commences.

Syntax

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

typedef struct {
  const char *Host;
  int Abort;
  int reserved;
} SMTPClientTLSHandshakeEventParams;


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

typedef struct {
  LPCWSTR Host;
  BOOL Abort;
  INT reserved;
} SMTPClientTLSHandshakeEventParams;

#define EID_SMTPCLIENT_TLSHANDSHAKE 14

virtual INT SECUREBLACKBOX_CALL FireTLSHandshake(LPSTR &lpszHost, BOOL &bAbort);

class SMTPClientTLSHandshakeEventParams {
public:
  const QString &Host();

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

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

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

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

Remarks

The class uses this event to notify the application about the start of a new TLS handshake to Host. If the handshake is successful, this event will be followed by the TLSEstablished event. If the server chooses to request a client certificate, the TLSCertNeeded event will also be fired.

TLSPSK Event (SMTPClient Class)

Notifies the application about the PSK key exchange.

Syntax

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

typedef struct {
  const char *Host;
  const char *Hint;
  int reserved;
} SMTPClientTLSPSKEventParams;


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

typedef struct {
  LPCWSTR Host;
  LPCWSTR Hint;
  INT reserved;
} SMTPClientTLSPSKEventParams;

#define EID_SMTPCLIENT_TLSPSK 15

virtual INT SECUREBLACKBOX_CALL FireTLSPSK(LPSTR &lpszHost, LPSTR &lpszHint);

class SMTPClientTLSPSKEventParams {
public:
  const QString &Host();

  const QString &Hint();

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

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

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

Remarks

The class fires this event to notify the application about the beginning of TLS-PSK key exchange with Host. The Hint parameter may be used by the server to identify the key or service to use. Use the PreSharedKey field of TLSSettings to provide the pre-shared key to the component.

TLSShutdown Event (SMTPClient Class)

Reports the graceful closure of a TLS connection.

Syntax

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

typedef struct {
  const char *Host;
  int reserved;
} SMTPClientTLSShutdownEventParams;


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

typedef struct {
  LPCWSTR Host;
  INT reserved;
} SMTPClientTLSShutdownEventParams;

#define EID_SMTPCLIENT_TLSSHUTDOWN 16

virtual INT SECUREBLACKBOX_CALL FireTLSShutdown(LPSTR &lpszHost);

class SMTPClientTLSShutdownEventParams {
public:
  const QString &Host();

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

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

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

Remarks

This event notifies the application about the closure of an earlier established TLS connection. Note that only graceful connection closures are reported.

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.

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
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 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

Certificate()

Creates a new object with default field values.

CRL Type

Represents a Certificate Revocation List.

Syntax

SecureBlackboxCRL (declared in secureblackbox.h)

Remarks

CRLs store information about revoked certificates, i.e., certificates that have been identified as invalid by their issuing certificate authority (CA) for any number of reasons.

Each CRL object lists certificates from a single CA and identifies them by their serial numbers. A CA may or may not publish a CRL, may publish several CRLs, or may publish the same CRL in multiple locations.

Unlike OCSP responses, CRLs only list certificates that have been revoked. They do not list certificates that are still valid.

The following fields are available:

Fields

Bytes
char* (read-only)
Default Value:

Returns the raw CRL data in DER format.

CAKeyID
char*
Default Value:

A unique identifier (fingerprint) of the CA certificate's private key, if present in the CRL.

EntryCount
int (read-only)
Default Value: 0

Returns the number of certificate status entries in the CRL.

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.

Issuer
char* (read-only)
Default Value: ""

The common name of the CRL issuer (CA), typically a company name.

IssuerRDN
char* (read-only)
Default Value: ""

A collection of information, in the form of [OID, Value] pairs, uniquely identifying the CRL issuer.

Location
char* (read-only)
Default Value: ""

The URL that the CRL was downloaded from.

NextUpdate
char*
Default Value: ""

The planned time and date of the next version of this CRL to be published.

SigAlgorithm
char*
Default Value: "0"

The public key algorithm that was used by the CA to sign this CRL.

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.

TBS
char* (read-only)
Default Value:

The to-be-signed part of the CRL (the CRL without the signature part).

ThisUpdate
char*
Default Value: ""

The date and time at which this version of the CRL was published.

Constructors

CRL()

Creates an empty CRL object.

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.

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.

Method
int
Default Value: 0

Specifies the asynchronous signing method. This is typically defined by the DC server capabilities and setup.

Available options:


asmdPKCS1	`0`
asmdPKCS7	`1`

Mode
int
Default Value: 0

Specifies the external cryptography mode.

Available options:


ecmDefault	The default value (`0`)
ecmDisabled	Do not use DC or external signing (`1`)
ecmGeneric	Generic external signing with the OnExternalSign event (`2`)
ecmDCAuth	DCAuth signing (`3`)
ecmDCAuthJSON	DCAuth signing in JSON format (`4`)

PublicKeyAlgorithm
char*
Default Value: ""

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

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.

Constructors

TLSSettings()

Creates a new TLSSettings object.

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 SMTPClient 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) {}

SecureBlackboxStream Type

Syntax

SecureBlackboxStream (declared in secureblackbox.h)

Remarks

The SMTPClient class includes one or more API members that take a stream object as a parameter. To use such API members, create a concrete class that implements the SecureBlackboxStream interface and pass the SMTPClient class an instance of that concrete class.

When implementing the SecureBlackboxStream interface's properties and methods, they must behave as described below. If the concrete class's implementation does not behave as expected, undefined behavior may occur.

Properties

CanRead	Whether the stream supports reading. bool CanRead() { return true; }
CanSeek	Whether the stream supports seeking. bool CanSeek() { return true; }
CanWrite	Whether the stream supports writing. bool CanWrite() { return true; }
Length	Gets the length of the stream, in bytes. int64 GetLength() = 0;
Methods

Close	Closes the stream, releasing all resources currently allocated for it. void Close() {} This method is called automatically when a SecureBlackboxStream object is deleted.
Flush	Forces all data held by the stream's buffers to be written out to storage. int Flush() { return 0; } Must return `0` if flushing is successful; or `-1` if an error occurs or the stream is closed. If the stream does not support writing, this method must do nothing and return `0`.
Read	Reads a sequence of bytes from the stream and advances the current position within the stream by the number of bytes read. int Read(void* buffer, int count) = 0; `Buffer` specifies the buffer to populate with data from the stream. `Count` specifies the number of bytes that should be read from the stream. Must return the total number of bytes read into `Buffer`; this may be less than `Count` if that many bytes are not currently available, or `0` if the end of the stream has been reached. Must return `-1` if an error occurs, if reading is not supported, or if the stream is closed.
Seek	Sets the current position within the stream based on a particular point of origin. int64 Seek(int64 offset, int seekOrigin) = 0; `Offset` specifies the offset in the stream to seek to, relative to `SeekOrigin`. Valid values for `SeekOrigin` are: `0`: Seek from beginning. `1`: Seek from current position. `2`: Seek from end. Must return the new position within the stream; or `-1` if an error occurs, if seeking is not supported, or if the stream is closed (however, see note below). If `-1` is returned, the current position within the stream must remain unchanged. Note: If the stream is not closed, it must always be possible to call this method with an `Offset` of `0` and a `SeekOrigin` of `1` to obtain the current position within the stream, even if seeking is not otherwise supported.
Write	Writes a sequence of bytes to the stream and advances the current position within the stream by the number of bytes written. int Write(const void* buffer, int count) = 0; `Buffer` specifies the buffer with data to write to the stream. `Count` specifies the number of bytes that should be written to the stream. Must return the total number of bytes written to the stream; this may be less than `Count` if that many bytes could not be written. Must return `-1` if an error occurs, if writing is not supported, or if the stream is closed.

Config Settings (SMTPClient 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.

SMTPClient Config Settings

Authentications: Specifies enabled authentication methods and their priorities.

Use this setting to enable or disable authentication methods and specify their priorities. The setting contains a comma-separated list of authentication methods. The first method in the list has the highest priority, and so on. The class will use the first method from the list which is supported by the server.

Supported methods: PLAIN, LOGIN, CRAM-MD5, DIGEST-MD5, NTLM, GSSAPI, XOAUTH2, SCRAM-SHA-1, SCRAM-SHA-256

Default value: SCRAM-SHA-256,SCRAM-SHA-1,DIGEST-MD5,CRAM-MD5,LOGIN,PLAIN

BinaryChunkSize: Specifies the size of chunks to use for dividing outgoing messages in binary mode.

Size of the chunks into which all messages are divided for sending in binary mode.

BinaryMode: Specifies whether binary mode is allowed for sending.

If the binary mode is allowed and SMTP server also supports this extension, the messages are sent in binary mode. In other cases messages are sent as text.

DSNOptions: Specifies the mode for Delivery Status Notifications (DSN).

Use this setting to set the delivery status(es) the SMTP server should report about. The setting contains a comma-separated list of DSN options.

Supported values: SUCCESS, FAILURE, DELAY

Default value: disabled (empty string)

DSNReturnInfo: Specifies notification return info for DSN.

Use this setting to instruct the SMTP server whether it should return a complete original message or only its headers in the notification.

Supported values: HEADERS, FULL

Default value: HEADERS

ForceLogin: Forces the class to login to the server.

If set to true, the class authencates on the server even if the server reports no supported authentication mechanisms.

IgnoreSystemTrust: Whether trusted Windows Certificate Stores should be treated as trusted.

Specifies whether, during chain validation, the class should respect the trust to CA certificates as configured in the operating system. In Windows this effectively defines whether the class should trust the certificates residing in the Trusted Root Certification Authorities store.

If IgnoreSystemTrust is True, certificates residing in the trusted root store are treated as if they are known, rather than trusted. Only certificates provided via other means (such as the TrustedCertificates property) are considered trusted.

RemoveBCC: Specifies if BCC header fields should be removed from messages.

Set the value to false to keep BCC fields in messages when sending. By default, the value is true, i.e. BCC fields are removed.

SendBufferSize: Size of send buffer in bytes.

The size of blocks used to send data to the server.

SessionLogDetails: Specifies whether login credentials should be written to the session log.

Use this setting to configure the details written to SessionLog. Possible values are:


default		Login credentials are not logged.
full		Login credentials appeare in the SessionLog.
none		No SessionLog is created.

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.

TempPath: Path for storing temporary files.

This setting specifies an absolute path to the location on disk where temporary files are stored.

TLSExtensions: TBD.

TBD

TLSPeerExtensions: TBD.

TBD

TLSSessionGroup: Specifies the group name of TLS sessions to be used for session resumption.

Use this property to limit the search of chached TLS sessions to the specified group. Sessions from other groups will be ignored. By default, all sessions are cached with an empty group name and available to all the classes.

TLSSessionLifetime: Specifies lifetime in seconds of the cached TLS session.

Use this property to specify how much time the TLS session should be kept in the session cache. After this time, the session expires and will be automatically removed from the cache. Default value is 300 seconds (5 minutes).

TLSSessionPurgeInterval: Specifies how often the session cache should remove the expired TLS sessions.

Use this property to specify the time interval of purging the expired TLS sessions from the session cache. Default value is 60 seconds (1 minute).

TolerateMinorChainIssues: Whether to tolerate minor chain issues.

This parameter controls whether the chain validator should tolerate minor technical issues when validating the chain. Those are:

CA, revocation source, TLS key usage requirements are not mandated
Violation of OCSP issuer requirements are ignored
The AuthorityKeyID extension in CRL- and certificate-issuing CAs are ignored (helps with incorrectly renewed certificates)
Basic constraints and name constraints of CA certificates are ignored
Some weaker algorithms are tolerated

UseMicrosoftCTL: Enables or disables the automatic use of the Microsoft online certificate trust list.

Enable this property to make the chain validation module automatically look up missing CA certificates in the public Windows Update repository.

UseSystemCertificates: Enables or disables the use of the system certificates.

Use this property to tell the chain validation module to automatically look up missing CA certificates in the system certificates. In many cases it is beneficial to switch this property on, as the operating system certificate configuration provides a representative trust framework.

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".

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


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)

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.

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:

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).

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.

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 (SMTPClient 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.
