The MessageEncryptor class encrypts data and stores it in the PKCS#7 format.

Syntax

MessageEncryptor

Remarks

PKCS#7 (Public Key Cryptography Standard #7) is a common format used to store encrypted and signed data. It is used by a variety of protocols, including S/MIME and CMS.

MessageEncryptor can encrypt binary data into PKCS#7 EnvelopedData (asymmetric encryption) and EncryptedData (symmetric encryption) subformats. RSA and ECDH key wrapping and all popular symmetric encryption algorithms are supported.

Setting up and using MessageEncryptor is easy:

• Set up your source and destination via InputFile (InputBytes) and OutputFile (OutputBytes) properties.
• Set EncryptionType as per the desired encryption type (asymmetric, symmetric, asymmetric with authentication).
• Set EncryptionAlgorithm and, optionally, BitsInKey (if the encryption algorithm uses variable key lengths).
• For certificate-based (asymmetric) encryption, put the encryption certificate (or all of them, if there are more than one) to the EncryptionCertificates collection.
• For key-based (symmetric) encryption, assign the symmetric key to Key property.
• Call Encrypt to execute the operation.

Note that MessageEncryptor always produces binary PKCS#7-compliant encrypted messages. For S/MIME email encryption, see MailWriter. For PGP encryption, see PGPWriter. For raw symmetric encryption, see SymmetricCrypto. For XML-ENC encryption, see XMLEncryptor.

 
 Copy
MessageEncryptor encryptor = new MessageEncryptor();

// Set the encryption algorithm (default AES128)
encryptor.setEncryptionAlgorithm("3DES");

// Select the file which contains the message that will be encrypted
encryptor.setInputFile("decryptedMessage.txt");

// Select the file where the encrypted message will be written
encryptor.setOutputFile("encryptedMessage.bin");

// We are using the public part of the certificate to encrypt data
encryptor.setEncryptionCertificate(new Certificate("cert.cer"));

encryptor.encrypt(); // Encrypt

AddAttribute Method (MessageEncryptor Class)

Adds an attribute to the signature.

Syntax

Remarks

Use this method to add a signed or unsigned attribute to the collection of attributes included in the new signature.

Note that CAdESSigner creates certain mandatory and/or widely used attributes automatically in accordance with requirements for a specific signing profile. For example, attributes such as SigningCertificateV2 or SigningTime are always added. Policy attributes are added if specified via the PolicyID or PolicyURI properties of the signature object.

Use the OID parameter to provide the object identifier of the attribute, in string form. For example, the OID for the SigningCertificateV2 attribute is 1.2.840.113549.1.9.16.2.47. The Value parameter should contain a well-formed, DER-encoded representation of the attribute value, in accordance with its specification.

Error Handling (C++)

This method returns an Integer 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.

Config Method (MessageEncryptor Class)

Sets or retrieves a configuration setting.

Syntax

• C++
• C
• Qt

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

Unicode (Windows)
LPWSTR Config(LPCWSTR lpszConfigurationString);

char* secureblackbox_messageencryptor_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.

DoAction Method (MessageEncryptor Class)

Performs an additional action.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* DoAction(const char* lpszActionID, const char* lpszActionParams);

char* secureblackbox_messageencryptor_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;....

Common ActionIDs:

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.

Encrypt Method (MessageEncryptor Class)

Encrypts data.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int Encrypt();

Unicode (Windows)
INT Encrypt();

int secureblackbox_messageencryptor_encrypt(void* lpObj);

int Encrypt();

Remarks

This method encrypts the data provided via InputFile or InputStream in accordance with PKCS#7 standard.

If encrypted with an EncryptionCertificate a message of EnvelopedData subtype is created. The private key that corresponds to the certificate is needed to decrypt the data.

If encrypted with Key, a message of EncryptedData subtype is formed. The receiving party needs the same key as provided in Key to decrypt the message.

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.)

Reset Method (MessageEncryptor Class)

Resets the class settings.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int Reset();

Unicode (Windows)
INT Reset();

int secureblackbox_messageencryptor_reset(void* lpObj);

int Reset();

Remarks

Reset is a generic method available in every class.

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.)

Error Event (MessageEncryptor Class)

Information about errors during PKCS#7 message encryption.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireError(MessageEncryptorErrorEventParams *e);

virtual int FireError(MessageEncryptorErrorEventParams *e) {...}

Remarks

};

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

// Or, subclass MessageEncryptor and override this emitter function.
virtual int FireNotification(MessageEncryptorNotificationEventParams *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.
