SignAndEncrypt Method

Signs and encrypts the current Message .

Syntax

smime.signAndEncrypt([callback])

Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for this method is defined as:

function(err){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

This method both signs and encrypts the message data included in Message into a single PKCS encoded envelope. The value in DetachedSignature 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.

The result of the encrypted data will be replaced in the Message property and the MessageHeaders property will be filled with the required S/MIME headers.

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.
