SignAndEncrypt Method

Signs and encrypts the current message.

Syntax

public void SignAndEncrypt();
Public Sub SignAndEncrypt()

Remarks

This method both signs and encrypts the input message into a single PKCS encoded envelope. The value in DetachedSignature is ignored: the component will always generate an attached signature when calling this method. All other properties used by calling the Sign and Encrypt methods are used in the same manner.

Please note that the message headers, including the Sender, Recipient(s), and Subject, are not encrypted. If this is sensitive information, consider including these headers in the message body as a MIME entity, and providing other headers for the S/MIME wrapper.
