ExternalCryptoKeyID Property (DTLSClient Class)
The ID of the pre-shared key used for DC request authentication.
Syntax
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 SetTLSRevocationCheck(int iTLSRevocationCheck);
Possible Values
CRC_NONE(0),
CRC_AUTO(1),
CRC_ALL_CRL(2),
CRC_ALL_OCSP(3),
CRC_ALL_CRLAND_OCSP(4),
CRC_ANY_CRL(5),
CRC_ANY_OCSP(6),
CRC_ANY_CRLOR_OCSP(7),
CRC_ANY_OCSPOR_CRL(8)
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.
crcNone (0) | No revocation checking |
crcAuto (1) | Automatic mode selection. Currently this maps to crcAnyOCSPOrCRL, but it may change in the future. |
crcAllCRL (2) | Check all provided CRL endpoints for all chain certificates. |
crcAllOCSP (3) | Check all provided OCSP endpoints for all chain certificates. |
crcAllCRLAndOCSP (4) | Check all CRL and OCSP endpoints for all chain certificates. |
crcAnyCRL (5) | At least one CRL check for every certificate in the chain must succeed. |
crcAnyOCSP (6) | At least one OCSP check for every certificate in the chain must succeed. |
crcAnyCRLOrOCSP (7) | At least one CRL or OCSP check for every certificate in the chain must succeed. CRL endpoints are checked first. |
crcAnyOCSPOrCRL (8) | At 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.
This property is not available at design time.

CertificateValidate Event (DTLSClient Class)
Fires when the server's TLS certificate has to be validated.
Syntax
class DTLSClientCertificateValidateEventParams { public: const QString &Address(); bool Accept(); void SetAccept(bool bAccept); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void CertificateValidate(DTLSClientCertificateValidateEventParams *e);
// Or, subclass DTLSClient and override this emitter function. virtual int FireCertificateValidate(DTLSClientCertificateValidateEventParams *e) {...}
Remarks
The class fires this event upon receiving the server's certificate during TLS handshake. The subscriber to this event has to validate the certificate and return its status back to the class using the Accept parameter.
The Address parameter indicates the address of the server the connection is being established to.
This event is fired independently of the AutoValidateCertificates setting. If this setting is false, the event handler (and your code) is responsible for validating the certificate chain and returning the result back to the component through the Accept parameter. Note that setting AutoValidateCertificates to false and not performing any validation inside the handler of this event creates a serious security vulnerability, which can lead to grave consequences.
The exact validation method to use depends on your circumstances, and may range from comparing the certificate to its legit and trusted copy (sometimes called certificate pinning), to fully-fledged chain validation. CertificateValidator component is one of the options to build your chain validation on.
If AutoValidateCertificates is true, the chain has already been validated internally by the component by the time this event fires, and the value of Accept reflects the outcome of that check. You can perform your own, additional validation even when using AutoValidateCertificates mode, and adjust Accept if needed.
Error Event (DTLSClient Class)
Information about errors during data delivery.
Syntax
class DTLSClientErrorEventParams { public: int ErrorCode(); const QString &Description(); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void Error(DTLSClientErrorEventParams *e);
// Or, subclass DTLSClient and override this emitter function. virtual int FireError(DTLSClientErrorEventParams *e) {...}
Remarks
The event is fired in case of exceptional conditions during message processing.
ErrorCode contains an error code and Description contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the HTTPS section.
ExternalSign Event (DTLSClient Class)
Handles remote or external signing initiated by the SignExternal method or other source.
Syntax
class DTLSClientExternalSignEventParams { 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(DTLSClientExternalSignEventParams *e);
// Or, subclass DTLSClient and override this emitter function. virtual int FireExternalSign(DTLSClientExternalSignEventParams *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();
};
Notification Event (DTLSClient Class)
This event notifies the application about an underlying control flow event.
Syntax
class DTLSClientNotificationEventParams { public: const QString &EventID(); const QString &EventParam(); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void Notification(DTLSClientNotificationEventParams *e);
// Or, subclass DTLSClient and override this emitter function. virtual int FireNotification(DTLSClientNotificationEventParams *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.
ReceivePlainData Event (DTLSClient Class)
TBD.
Syntax

Configuration Settings (DTLSClient 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.DTLSClient Configuration Settings | ||||||||||||||||||||||||||||||
DatagramSize: Specifies maximum size of the datagram.Use this property to get or set maximum size of the datagram. Data pieces larger than DatagramSize will be split into several smaller datagrams with lengths smaller (or equal) to the DatagramSize. | ||||||||||||||||||||||||||||||
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. |
||||||||||||||||||||||||||||||
MaxDataSize: Specifies maximum size of the packet which will not be divided into smaller ones.Use this read-only property to get the maximum size of the data piece which will not be divided into smaller ones. The value of this property is smaller or equal to the DatagramSize. | ||||||||||||||||||||||||||||||
RetransmissionInterval: Specifies value of the retransmission interval.Use this property to specify the period of time in milliseconds, after which the client will repeat sending. Set this property to 0 to disable the retransmission timer. Defaul value is 1000 (i.e. 1 second). | ||||||||||||||||||||||||||||||
SplitLongData: Specifies whether to split long datagrams into smaller ones.If this prperty is set to True, datagrams larger than MaxDataSize will be split into smaller ones. Default value is True. | ||||||||||||||||||||||||||||||
TolerateMinorChainIssues: Whether to tolerate minor chain issues.TBD | ||||||||||||||||||||||||||||||
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 Configuration 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:
|
||||||||||||||||||||||||||||||
Cookies: Gets or sets local cookies for the class (supported for HTTPClient, RESTClient and SOAPClient only).Use this property to get cookies from the internal cookie storage of the class and/or restore them back between application sessions. | ||||||||||||||||||||||||||||||
DefDeriveKeyIterations: Specifies the default key derivation algorithm iteration count.This global property sets the default number of iterations for all supported key derivation algorithms. Note that you can provide the required number of iterations by using properties of the relevant key generation component; this global setting is used in scenarios where specific iteration count is not or cannot be provided. | ||||||||||||||||||||||||||||||
EnableClientSideSSLFFDHE:
Enables or disables finite field DHE key exchange support in TLS clients.This global property enables or disables support for finite field DHE key exchange methods in TLS clients. FF DHE is a slower
algorithm if compared to EC DHE; enabling it may result in slower connections.
This setting only applies to sessions negotiated with TLS version 1.3. |
||||||||||||||||||||||||||||||
GlobalCookies: Gets or sets global cookies for all the HTTP transports.Use this property to get cookies from the GLOBAL cookie storage or restore them back between application sessions. These cookies will be used by all the classes that have its CookieCaching property set to "global". | ||||||||||||||||||||||||||||||
HttpUserAgent: Specifies the user agent name to be used by all HTTP clients.This global setting defines the User-Agent field of the HTTP request provides information about the software that initiates the request. This value will be used by all the HTTP clients including the ones used internally in other classes. | ||||||||||||||||||||||||||||||
LogDestination:
Specifies the debug log destination.Contains a comma-separated list of values that specifies where debug log should be dumped.
Supported values are:
|
||||||||||||||||||||||||||||||
LogDetails:
Specifies the debug log details to dump.Contains a comma-separated list of values that specifies which debug log details to dump.
Supported values are:
|
||||||||||||||||||||||||||||||
LogFile: Specifies the debug log filename.Use this property to provide a path to the log file. | ||||||||||||||||||||||||||||||
LogFilters:
Specifies the debug log filters.Contains a comma-separated list of value pairs ("name:value") that describe filters.
Supported filter names are:
|
||||||||||||||||||||||||||||||
LogFlushMode:
Specifies the log flush mode.Use this property to set the log flush mode. The following values are defined:
|
||||||||||||||||||||||||||||||
LogLevel:
Specifies the debug log level.Use this property to provide the desired debug log level.
Supported values are:
|
||||||||||||||||||||||||||||||
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:
|
||||||||||||||||||||||||||||||
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. | ||||||||||||||||||||||||||||||
Tag: Allows to store any custom data.Use this config property to store any custom data. | ||||||||||||||||||||||||||||||
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. |
