sign_and_encrypt Method

Signs and encrypts the current message.

Syntax

def sign_and_encrypt() -> None: ...

Remarks

This method both signs and encrypts the input message into a single PKCS encoded envelope. The value in detached_signature is ignored: the class 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.
