Interface SignedInfo

All Superinterfaces:

XMLStructure
```
public interface SignedInfo
extends XMLStructure
```
An representation of the XML SignedInfo element as defined in the W3C Recommendation for XML-Signature Syntax and Processing. The XML Schema Definition is defined as:
```
 <element name="SignedInfo" type="ds:SignedInfoType"/>
 <complexType name="SignedInfoType">
   <sequence>
     <element ref="ds:CanonicalizationMethod"/>
     <element ref="ds:SignatureMethod"/>
     <element ref="ds:Reference" maxOccurs="unbounded"/>
   </sequence>
   <attribute name="Id" type="ID" use="optional"/>
 </complexType>
 
```
A SignedInfo instance may be created by invoking one of the newSignedInfo methods of the XMLSignatureFactory class.
Since:

1.6
