The MailWriter component composes, encrypts, and signs e-mail messages.

Syntax

TsbxMailWriter

Remarks

Use MailWriter to compose, sign, and encrypt e-mail messages, and prepare them for sending or saving.

Preparing a very simple message and saving it to a file: MailWriter writer = new MailWriter(); writer.From.Add(new MailAddress("John Doe", "jdoe@company.com")); writer.SendTo.Add(new MailAddress("Mary Dow", "mdow@home.com")); writer.Message.Subject = "Lating to the party"; writer.Message.PlainText = "Hi Mary!\r\nStill in the office waiting for my partner.\r\nProbably I'll be late to the party for about an hour.\r\nSorry.\r\nJohn"; writer.SaveToFile("path\\message.eml");

Attaching an image and referencing it from the message text: writer.AttachImage("myimage", File.ReadAllBytes("path\\image.jpg")); writer.Attachments[0].ContentSubtype = "jpeg"; writer.Message.HtmlText = "<html><body>Message with an image<p><img src=\"cid:myimage\"></body></html>";

Signing a message with a certificate (note that the certificate should contain its private key): CertificateManager manager = new CertificateManager(); manager.ImportFromFile("path\\cert.pfx", "password"); writer.SecuritySettings.Sign = true; writer.SecuritySettings.HashAlgorithm = "SHA256"; writer.SigningCertificate = manager.Certificate; writer.SaveToFile("path\\message.eml");

Encrypting a message with one or more certificates (no private key is required): CertificateManager manager = new CertificateManager(); manager.ImportFromFile("path\\cert.cer", ""); writer.SecuritySettings.Encrypt = true; writer.SecuritySettings.EncryptionAlgorithm = "AES256"; writer.EncryptionCertificates.Add(manager.Certificate); // add more certificates if needed writer.SaveToFile("D:\\test.eml");

ExternalCryptoKeyID Property (MailWriter Component)

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

Syntax

__property String ExternalCryptoKeyID = { read=FExternalCryptoKeyID, write=FSetExternalCryptoKeyID };

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 an extra protection layer for the protocol and diminishes the risk of the 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 (MailWriter Component)

The pre-shared key used for DC request authentication.

Syntax

__property String ExternalCryptoKeySecret = { read=FExternalCryptoKeySecret, write=FSetExternalCryptoKeySecret };

Default Value

Remarks

The pre-shared key used for DC request authentication. This key must be set and match the key used by the DCAuth counterpart for the scheme to work.

Remarks

Config is a generic method available in every component. It is used to set and retrieve configuration settings for the component.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, 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.

CreateNew Method (MailWriter Component)

ExternalSign Event (MailWriter Component)

Handles remote or external signing initiated by the SignExternal method or other source.

Syntax

typedef struct {
  String OperationId;
  String HashAlgorithm;
  String Pars;
  String Data;
  String SignedData;
} TsbxMailWriterExternalSignEventParams;
typedef void __fastcall (__closure *TsbxMailWriterExternalSignEvent)(System::TObject* Sender, TsbxMailWriterExternalSignEventParams *e);
__property TsbxMailWriterExternalSignEvent OnExternalSign = { read=FOnExternalSign, write=FOnExternalSign };

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 the 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 contains algorithm-dependent parameters.

The component uses base16 (hex) encoding for the 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 the .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 (MailWriter Component)

This event notifies the application about an underlying control flow event.

Syntax

typedef struct {
  String EventID;
  String EventParam;
} TsbxMailWriterNotificationEventParams;
typedef void __fastcall (__closure *TsbxMailWriterNotificationEvent)(System::TObject* Sender, TsbxMailWriterNotificationEventParams *e);
__property TsbxMailWriterNotificationEvent OnNotification = { read=FOnNotification, write=FOnNotification };

Remarks

The component 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 the 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.

Config Settings (MailWriter Component)

The component accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used.

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 component is set to "local", the property returns/restores the rules from/to the internal storage of the component. If StaticDNS of the component 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.
