Resource: signature.dsa.xml
The example uses a signature file, which contains internally referenced text data that has been signed. This file has the following characteristics:
- The signed text data is a string, "Hello, World!". This string is held as the content of a
<ds:Object Id="HelloWorld">
element. - The signature method used is http://www.w3.org/2000/09/xmldsig#dsa-sha1.
- The key information is given in an
<ds:KeyInfo>
element, which will be retrieved by thecreateKeyFromNode
method before the signature is verified.
