ExternalCryptoKeyID Property (MessageDecryptor 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

Data Type
String
Config Method (MessageDecryptor Class)
Sets or retrieves a configuration setting.
Syntax
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
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.
Decrypt Method (MessageDecryptor Class)
Attempts to decrypt an encrypted PKCS#7 message.
Syntax
int Decrypt();
Remarks
Call this method to attempt to decrypt the PKCS#7 encrypted data. This call supports EnvelopedData and EncryptedData subtypes on input.
Use InputFile or InputStream property to provide the data, and either Certificates or Key to supply the decryption key material.
When processing enveloped data, the class may fire RecipientFound event to report recipient information.
Error Handling
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.)
DoAction Method (MessageDecryptor Class)
Performs an additional action.
Syntax
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 of the action is provided in ActionID parameter. ActionParams contains a list of parameters for the action in the form of PARAM1=VALUE1;PARAM2=VALUE2;....
Error Handling
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.
Error Event (MessageDecryptor Class)
Information about errors during PKCS#7 message decryption.
Syntax
class MessageDecryptorErrorEventParams {
public:
int ErrorCode();
const QString &Description();
int EventRetVal();
void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal.
void Error(MessageDecryptorErrorEventParams *e);
// Or, subclass MessageDecryptor and override this emitter function.
virtual int FireError(MessageDecryptorErrorEventParams *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 Messages section.
ExternalDecrypt Event (MessageDecryptor Class)
Handles remote or external decryption.
Syntax
class MessageDecryptorExternalDecryptEventParams {
public:
const QString &OperationId();
const QString &Algorithm();
const QString &Pars();
const QString &EncryptedData();
const QString &Data();
void SetData(const QString &qsData);
int EventRetVal();
void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal.
void ExternalDecrypt(MessageDecryptorExternalDecryptEventParams *e);
// Or, subclass MessageDecryptor and override this emitter function.
virtual int FireExternalDecrypt(MessageDecryptorExternalDecryptEventParams *e) {...}
Remarks
Assign a handler to this event if you need to delegate a low-level decryption operation to an external, remote, or custom decryption engine. The handler receives a encrypted value in the EncryptedData parameter, and is expected to decrypt it and place the decrypted value into the Data parameter.
OperationId provides a comment about the operation and its origin. It depends on the exact component being used, and may be empty. Algorithm specifies the encryption algorithm being used, and Pars contain algorithm-dependent parameters.
The component uses base16 (hex) encoding for EncryptedData, Data, and Pars parameters. If your decryption engine uses a different input and output encoding, you may need to decode and/or encode the data before and/or after the decryption.
A sample data encoded in base16: a0dee2a0382afbb09120ffa7ccd8a152 - lower case base16 A0DEE2A0382AFBB09120FFA7CCD8A152 - upper case base16
Notification Event (MessageDecryptor Class)
This event notifies the application about an underlying control flow event.
Syntax
class MessageDecryptorNotificationEventParams {
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(MessageDecryptorNotificationEventParams *e);
// Or, subclass MessageDecryptor and override this emitter function.
virtual int FireNotification(MessageDecryptorNotificationEventParams *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.
RecipientFound Event (MessageDecryptor Class)
Fires to report a message addressee parameters.
Syntax
class MessageDecryptorRecipientFoundEventParams {
public:
const QString &IssuerRDN();
const QByteArray &SerialNumber();
const QByteArray &SubjectKeyID();
bool CertFound();
int EventRetVal();
void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal.
void RecipientFound(MessageDecryptorRecipientFoundEventParams *e);
// Or, subclass MessageDecryptor and override this emitter function.
virtual int FireRecipientFound(MessageDecryptorRecipientFoundEventParams *e) {...}
Remarks
This event is fired for each addressee the message is encrypted for. It may fire several times in a row if the message is encrypted for more than one recipient.
The IssuerRDN, SerialNumber, and SubjectKeyID parameters to identify the recipient's certificate. CertFound indicates if the specified certificate has been located in Certificates collection. If it wasn't, you might want to look up the certificate manually, and add it to the collection inside the event handler.
Configuration Settings (MessageDecryptor 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.MessageDecryptor Configuration Settings | ||||||||||||||||||||||||||||||
