For the default property values used with this constructor, see SignedCms().
If the detached state is false (the default), the content that is signed is included in the CMS/PKCS #7 message along with the signature information. If the detached state is true, clients that cannot decode S/MIME messages can still see the content of the message if it is sent separately. This might be useful in an archiving application that archives message content whether the message sender can be verified for authenticity.
