Structure of XML: (CanonicalizationMethod)? (SignatureMethod) (Transforms)? (DigestMethod) (DigestValue) )+ (SignatureValue) (KeyInfo)? (Object)* DigestValue: DigestValue contains the Base64 encoded result of applying the hash algorithm to the transformed resource(s) defined in the Reference element attributes. Validation: Reference Validation: Each Reference's digest is verified by retrieving the corresponding resource and applying any transforms and then the specified digest method to it. The result is compared to the recorded DigestValue ; if they do not match validation fails. Mark as answer if helpful.
