Property

Default value

ContentInfo

1.2.840.113549.1.7.1 (data)Length: zero

Detached

Detached state: false The content that is signed is included in the CMS/PKCS #7 message along with the signature information.

The default SubjectIdentifierType for signers is SubjectIdentifierType.IssuerAndSerialNumber.

If the detached state is false (the default), the signed content 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 may be useful in an archiving application that archives message content whether the message sender can be verified for authenticity.
