The SignedXml class is the principle class used to
create and verify XML signatures. References to data are associated
with a signature document through the AddReference(
) method, while data objects are associated through the
AddObject( ) method. The
ComputeSignature( ) method performs a signature
operation, while the CheckSignature( ) method
verifies an existing XML Signature.
