ExternalCryptoKeyID Property (POP3Client 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
ExternalCryptoKeySecret Property (POP3Client Class)

CRC_ANY_OCSP(6),
CRC_ANY_CRLOR_OCSP(7),

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.

BeforeAuth Event (POP3Client Class)
Fires before the authentication starts.
Syntax
class POP3ClientBeforeAuthEventParams { public: int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void BeforeAuth(POP3ClientBeforeAuthEventParams *e);
// Or, subclass POP3Client and override this emitter function. virtual int FireBeforeAuth(POP3ClientBeforeAuthEventParams *e) {...}
Remarks
The class fires this event when it has established the TCP connection and is ready to proceed to the user authentication step.
CertificateValidate Event (POP3Client Class)
Fires when the server's TLS certificate has to be validated.
Syntax
class POP3ClientCertificateValidateEventParams { 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(POP3ClientCertificateValidateEventParams *e);
// Or, subclass POP3Client and override this emitter function. virtual int FireCertificateValidate(POP3ClientCertificateValidateEventParams *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.
Command Event (POP3Client Class)
Reports a command sent to the server.
Syntax
class POP3ClientCommandEventParams { public: const QString &Cmd(); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void Command(POP3ClientCommandEventParams *e);
// Or, subclass POP3Client and override this emitter function. virtual int FireCommand(POP3ClientCommandEventParams *e) {...}
Remarks
The class fires this event whenever it sends a POP3 command to the server. Use CommandReply and CommandReplyData to track the server's responses.
CommandReply Event (POP3Client Class)
Reports the receipt of a reply to a command.
Syntax
class POP3ClientCommandReplyEventParams { public: const QString &Cmd(); const QString &Reply(); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void CommandReply(POP3ClientCommandReplyEventParams *e);
// Or, subclass POP3Client and override this emitter function. virtual int FireCommandReply(POP3ClientCommandReplyEventParams *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, and CommandReplyData to access the reply data for commands that assume it.
CommandReplyData Event (POP3Client Class)
Returns the data that accompanies a reply to a command.
Syntax
class POP3ClientCommandReplyDataEventParams { public: const QString &Cmd(); const QString &Data(); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void CommandReplyData(POP3ClientCommandReplyDataEventParams *e);
// Or, subclass POP3Client and override this emitter function. virtual int FireCommandReplyData(POP3ClientCommandReplyDataEventParams *e) {...}
Remarks

Syntax
class POP3ClientErrorEventParams { public: int ErrorCode(); const QString &Description(); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void Error(POP3ClientErrorEventParams *e);
// Or, subclass POP3Client and override this emitter function. virtual int FireError(POP3ClientErrorEventParams *e) {...}
Remarks
This event is fired in case of exceptional conditions occured during POP3 operations.
ErrorCode contains an error code and Description contains a textual description of the error.
ExternalSign Event (POP3Client Class)
Handles remote or external signing initiated by the SignExternal method or other source.
Syntax
class POP3ClientExternalSignEventParams { 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(POP3ClientExternalSignEventParams *e);
// Or, subclass POP3Client and override this emitter function. virtual int FireExternalSign(POP3ClientExternalSignEventParams *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 (POP3Client Class)
This event notifies the application about an underlying control flow event.
Syntax
class POP3ClientNotificationEventParams { 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(POP3ClientNotificationEventParams *e);
// Or, subclass POP3Client and override this emitter function. virtual int FireNotification(POP3ClientNotificationEventParams *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 (POP3Client Class)
Reports the progress of the data transfer operation.
Syntax
class POP3ClientProgressEventParams { public: qint64 Total(); qint64 Current(); bool Cancel(); void SetCancel(bool bCancel); int EventRetVal(); void SetEventRetVal(int iRetVal); };

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.
