SignedCms Constructor (SubjectIdentifierType)

 

The SignedCms(SubjectIdentifierType) constructor creates an instance of the SignedCms class by using the specified subject identifier type as the default subject identifier type for signers.

Namespace:   System.Security.Cryptography.Pkcs
Assembly:  System.Security (in System.Security.dll)

public SignedCms(
	SubjectIdentifierType signerIdentifierType
)

Parameters

signerIdentifierType
Type: System.Security.Cryptography.Pkcs.SubjectIdentifierType

A SubjectIdentifierType member that specifies the default subject identifier type for signers.

Exception Condition
ArgumentNullException

A null reference was passed to a method that does not accept it as a valid argument.

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.
