public class SignedInfo : ICollection


The System.Security.Cryptography.Xml.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 System.Security.Cryptography.Xml.SignedInfo class available from the SignedXml.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
