SignAndEncrypt Method

Signs and encrypts the current message.

procedure 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.

Input and Output Properties

The component will determine the source and destination of the input and output based on which properties are set.

The order in which the input properties are checked is as follows:

• SetInputStream
• InputFile
• InputMessage

When a valid source is found the search stops. The order in which the output properties are checked is as follows:

• SetOutputStream
• OutputFile
• OutputMessage: The output data is written to this property if no other destination is specified.

When using streams you may need to additionally set CloseInputStreamAfterProcessing or CloseOutputStreamAfterProcessing.

The headers of the input message (if any) will be read from InputMessageHeaders or InputMessageHeadersString.

The headers of the resulting message will be available in the OutputMessageHeaders and OutputMessageHeadersString properties.
