SignAndEncrypt Method

Signs and encrypts the current message.

Syntax

ANSI (Cross Platform)
int SignAndEncrypt();

Unicode (Windows)
INT SignAndEncrypt();
- (void)signAndEncrypt;
#define MID_SHTMLMAILER_SIGNANDENCRYPT 17

IPWORKSSMIME_EXTERNAL int IPWORKSSMIME_CALL IPWorksSMIME_SHTMLMailer_Do(void *lpObj, int methid, int cparam, void *param[], int cbparam[], int64 *lpllVal);

Remarks

This method both signs and encrypts the input message into a single PKCS encoded envelope.

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.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
