SignedInfo SignedInfo SignedInfo SignedInfo Class


Contains information about the canonicalization algorithm and signature algorithm used for the XML signature.

public ref class SignedInfo : System::Collections::ICollection
public class SignedInfo : System.Collections.ICollection
type SignedInfo = class
    interface ICollection
    interface IEnumerable
Public Class SignedInfo
Implements ICollection


The SignedInfo class represents the <SignedInfo> element of an XML signature defined by the XML digital signature specification. The <SignedInfo> element, which is a subelement of the <Signature> element, contains the canonicalization method used for signing, the algorithm used for signing and validation, and references that describe a digital signature.

For most scenarios, you should use the SignedInfo class available from the SignedInfo property to sign and verify XML digital signatures.

For more information about the <SignedInfo> element, see the World Wide Web Consortium (W3C) specification at
