Syntax

class secureblackbox.MailWriter

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");

external_crypto_key_id Property

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

Syntax

def get_external_crypto_key_id() -> str: ...
def set_external_crypto_key_id(value: str) -> None: ...

external_crypto_key_id = property(get_external_crypto_key_id, set_external_crypto_key_id)

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 external_crypto_key_secret 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.

# In class MailWriter:
@property
def on_error() -> Callable[[MailWriterErrorEventParams], None]: ...
@on_error.setter
def on_error(event_hook: Callable[[MailWriterErrorEventParams], None]) -> None: ...

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.

on_external_sign Event

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

Syntax

class MailWriterExternalSignEventParams(object):
  @property
  def operation_id() -> str: ...

# In class MailWriter:
@property
def on_external_sign() -> Callable[[MailWriterExternalSignEventParams], None]: ...
@on_external_sign.setter
def on_external_sign(event_hook: Callable[[MailWriterExternalSignEventParams], None]) -> None: ...

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 class via the SignedData parameter.

OperationId provides a comment about the operation and its origin. It depends on the exact class being used, and may be empty. HashAlgorithm specifies the hash algorithm being used for the operation, and Pars contains algorithm-dependent parameters.

The class 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(); };

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

Syntax

class MailWriterNotificationEventParams(object):
  @property
  def event_id() -> str: ...

  @property
  def event_param() -> str: ...

# In class MailWriter:
@property
def on_notification() -> Callable[[MailWriterNotificationEventParams], None]: ...
@on_notification.setter
def on_notification(event_hook: Callable[[MailWriterNotificationEventParams], None]) -> None: ...

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.

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 class, the exact action it is performing, or the document being processed, one or both may be omitted.

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.
