ExternalCryptoKeyID Property (SMTPClient Class)

The ID of the pre-shared key used for DC request authentication.

Syntax

ANSI (Cross Platform)
char* GetExternalCryptoKeyID();
int SetExternalCryptoKeyID(const char* lpszExternalCryptoKeyID); Unicode (Windows) LPWSTR GetExternalCryptoKeyID();
INT SetExternalCryptoKeyID(LPCWSTR lpszExternalCryptoKeyID);

QString GetExternalCryptoKeyID();
int SetExternalCryptoKeyID(QString qsExternalCryptoKeyID);

Default Value

""

Remarks

The ID of the pre-shared key used for DC request authentication.

Asynchronous DCAuth-driven communication requires that parties authenticate each other with a secret pre-shared cryptographic key. This provides extra protection layer for the protocol and diminishes the risk of private key becoming abused by foreign parties. Use this property to provide the pre-shared key identifier, and use ExternalCryptoKeySecret to pass the key itself.

The same KeyID/KeySecret pair should be used on the DCAuth side for the signing requests to be accepted.

Note: The KeyID/KeySecret scheme is very similar to the AuthKey scheme used in various Cloud service providers to authenticate users.

Example: signer.ExternalCrypto.KeyID = "MainSigningKey"; signer.ExternalCrypto.KeySecret = "abcdef0123456789";

Data Type

String

int secureblackbox_smtpclient_settlsrevocationcheck(void* lpObj, int iTLSRevocationCheck);
int GetTLSRevocationCheck();
int SetTLSRevocationCheck(int iTLSRevocationCheck);

Default Value

1

Remarks

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

Revocation checking is necessary to ensure the integrity of the chain and obtain up-to-date certificate validity and trustworthiness information.

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

This setting controls the way the revocation checks are performed. Typically certificates come with two types of revocation information sources: CRL (certificate revocation lists) and OCSP responders. CRLs are static objects periodically published by the CA at some online location. OCSP responders are active online services maintained by the CA that can provide up-to-date information on certificate statuses in near real time.

There are some conceptual differences between the two. CRLs are normally larger in size. Their use involves some latency because there is normally some delay between the time when a certificate was revoked and the time the subsequent CRL mentioning that is published. The benefits of CRL is that the same object can provide statuses for all certificates issued by a particular CA, and that the whole technology is much simpler than OCSP (and thus is supported by more CAs).

This setting lets you adjust the validation course by including or excluding certain types of revocation sources from the validation process. The crcAnyOCSPOrCRL setting (give preference to faster OCSP route and only demand one source to succeed) is a good choice for most of typical validation environments. The "crcAll*" modes are much stricter, and may be used in scenarios where bulletproof validity information is essential.

// To handle, connect one or more slots to this signal. void CommandReply(SMTPClientCommandReplyEventParams *e);
// Or, subclass SMTPClient and override this emitter function. virtual int FireCommandReply(SMTPClientCommandReplyEventParams *e) {...}

Remarks

Use this event to track command replies sent in by the server. Use Command to track the commands sent out by the client.

Error Event (SMTPClient Class)

Provides information about errors during SMTP operations.

Syntax

ANSI (Cross Platform)
virtual int FireError(SMTPClientErrorEventParams *e);
typedef struct {
int ErrorCode;
const char *Description; int reserved; } SMTPClientErrorEventParams;
Unicode (Windows) virtual INT FireError(SMTPClientErrorEventParams *e);
typedef struct {
INT ErrorCode;
LPCWSTR Description; INT reserved; } SMTPClientErrorEventParams;
#define EID_SMTPCLIENT_ERROR 5

virtual INT SECUREBLACKBOX_CALL FireError(INT &iErrorCode, LPSTR &lpszDescription);
class SMTPClientErrorEventParams {
public:
  int ErrorCode();

  const QString &Description();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void Error(SMTPClientErrorEventParams *e);
// Or, subclass SMTPClient and override this emitter function. virtual int FireError(SMTPClientErrorEventParams *e) {...}

Remarks

This event is fired in case of exceptional conditions occured during SMTP operations.

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) virtual INT FireExternalSign(SMTPClientExternalSignEventParams *e);
typedef struct {
LPCWSTR OperationId;
LPCWSTR HashAlgorithm;
LPCWSTR Pars;
LPCWSTR Data;
LPWSTR SignedData; INT reserved; } SMTPClientExternalSignEventParams;
#define EID_SMTPCLIENT_EXTERNALSIGN 6

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 component via SignedData parameter.

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

The component uses base16 (hex) encoding for Data, SignedData, and Pars parameters. If your signing engine uses a different input and output encoding, you may need to decode and/or encode the data before and/or after the signing.

A sample MD5 hash encoded in base16: a0dee2a0382afbb09120ffa7ccd8a152 - lower case base16 A0DEE2A0382AFBB09120FFA7CCD8A152 - upper case base16

A sample event handler that uses a .NET RSACryptoServiceProvider class may look like the following: signer.OnExternalSign += (s, e) => { var cert = new X509Certificate2("cert.pfx", "", X509KeyStorageFlags.Exportable); var key = (RSACryptoServiceProvider)cert.PrivateKey; var dataToSign = e.Data.FromBase16String(); var signedData = key.SignHash(dataToSign, "2.16.840.1.101.3.4.2.1"); e.SignedData = signedData.ToBase16String(); };

};
// 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 component. For example, it may fire to report completion of the document processing. The list of events being reported is not fixed, and may be flexibly extended over time.

The unique identifier of the event is provided in EventID parameter. EventParam contains any parameters accompanying the occurrence. Depending on the type of the component, the exact action it is performing, or the document being processed, one or both may be omitted.

Progress Event (SMTPClient Class)

Reports the progress of the data transfer operation.

Syntax

ANSI (Cross Platform)
virtual int FireProgress(SMTPClientProgressEventParams *e);

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);

  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 (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;

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 TLSServerChain property to access the certificate chain. In general case, components 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 component, 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;

  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 successful completion of a TLS handshake.

The Version, Ciphersuite, and ConnectionId parameters indicate 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 12

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 with TLSEstablished event. If the server chooses to request a client certificate, 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;

  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);

#define EID_SMTPCLIENT_TLSSHUTDOWN 14

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.

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: LOGIN,PLAIN,DIGEST-MD5,CRAM-MD5,NTLM

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 component should respect the trust to CA certificates as configured in the operating system. In Windows this effectively defines whether the component 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 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.

TempPath:   Path for storing temporary files.

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

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
  • 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 automatic use of 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 chain validation module 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

CheckKeyIntegrityBeforeUse:   Enables or disable private key integrity check before use.

This global property enables or disables private key material check before each signing operation. This slows down performance a bit, but prevents a selection of attacks on RSA keys where keys with unknown origins are used.

You can switch this property off to improve performance if your project only uses known, good private keys.

CookieCaching:   Specifies whether a cookie cache should be used for HTTP(S) transports.

Set this property to enable or disable cookies caching for the class.

Supported values are:

offNo caching (default)
localLocal caching
globalGlobal 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.

EnableClientSideSSLFFDHE:   Enables or disables finite field DHE key exchange support in TLS clients.

This global property enables or disables support for finite field DHE key exchange methods in TLS clients. FF DHE is a slower algorithm if compared to EC DHE; enabling it may result in slower connections.

This setting only applies to sessions negotiated with TLS version 1.3.

GlobalCookies:   Gets or sets global cookies for all the HTTP transports.

Use this property to get cookies from the GLOBAL cookie storage or restore them back between application sessions. These cookies will be used by all the classes that have its CookieCaching property set to "global".

HttpUserAgent:   Specifies the user agent name to be used by all HTTP clients.

This global setting defines the User-Agent field of the HTTP request provides information about the software that initiates the request. This value will be used by all the HTTP clients including the ones used internally in other classes.

LogDestination:   Specifies the debug log destination.

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

Supported values are:

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

LogFlushMode:   Specifies the log flush mode.

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

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

LogLevel:   Specifies the debug log level.

Use this property to provide the desired debug log level.

Supported values are:

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

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

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

The default value of this setting is 100.

LogRotationMode:   Specifies the log rotation mode.

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

noneNo rotation
deleteolderDelete older entries from the cache upon reaching LogMaxEventCount
keepolderKeep older entries in the cache upon reaching LogMaxEventCount (newer entries are discarded)

MaxASN1BufferLength:   Specifies the maximal allowed length for ASN.1 primitive tag data.

This global property limits the maximal allowed length for ASN.1 tag data for non-content-carrying structures, such as certificates, CRLs, or timestamps. It does not affect structures that can carry content, such as CMS/CAdES messages. This is a security property aiming at preventing DoS attacks.

MaxASN1TreeDepth:   Specifies the maximal depth for processed ASN.1 trees.

This global property limits the maximal depth of ASN.1 trees that the component can handle without throwing an error. This is a security property aiming at preventing DoS attacks.

OCSPHashAlgorithm:   Specifies the hash algorithm to be used to identify certificates in OCSP requests.

This global setting defines the hash algorithm to use in OCSP requests during chain validation. Some OCSP responders can only use older algorithms, in which case setting this property to SHA1 may be helpful.

StaticDNS:   Specifies whether static DNS rules should be used.

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

Supported values are:

noneNo static DNS rules (default)
localLocal static DNS rules
globalGlobal static DNS rules

StaticIPAddress[domain]:   Gets or sets an IP address for the specified domain name.

Use this property to get or set an IP address for the specified domain name in the internal (of the class) or global DNS rules storage depending on the StaticDNS value. The type of the IP address (IPv4 or IPv6) is determined automatically. If both addresses are available, they are devided by the | (pipe) character.

StaticIPAddresses:   Gets or sets all the static DNS rules.

Use this property to get static DNS rules from the current rules storage or restore them back between application sessions. If StaticDNS of the class is set to "local", the property returns/restores the rules from/to the internal storage of the class. If StaticDNS of the class is set to "global", the property returns/restores the rules from/to the GLOBAL storage. The rules list is returned and accepted in JSON format.

Tag:   Allows to store any custom data.

Use this config property to store any custom data.

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

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

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

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

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

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

UseOwnDNSResolver:   Specifies whether the client components should use own DNS resolver.

Set this global property to false to force all the client components to use the DNS resolver provided by the target OS instead of using own one.

UseSharedSystemStorages:   Specifies whether the validation engine should use a global per-process copy of the system certificate stores.

Set this global property to false to make each validation run use its own copy of system certificate stores.

UseSystemOAEPAndPSS:   Enforces or disables the use of system-driven RSA OAEP and PSS computations.

This global setting defines who is responsible for performing RSA-OAEP and RSA-PSS computations where the private key is stored in a Windows system store and is exportable. If set to true, SBB will delegate the computations to Windows via a CryptoAPI call. Otherwise, it will export the key material and perform the computations using its own OAEP/PSS implementation.

This setting only applies to certificates originating from a Windows system store.

UseSystemRandom:   Enables or disables the use of the OS PRNG.

Use this global property to enable or disable the use of operating system-driven pseudorandom number generation.

Trappable Errors (SMTPClient Class)
