XML: Add Base64 transform to reference
TElXMLBase64Transform class represents the Base64 transform for an XML digital signature as defined by the XML-DSig standard.
To add Base64 transform to the reference transform chain you need to create an instance of TElXMLBase64Transform class and then add it to the chain.
C#:
TElXMLReference Ref = new TElXMLReference();
Ref.TransformChain.Add(new TElXMLBase64Transform());
Delphi:
var Ref : TElXMLReference;
...
Ref := TElXMLReference.Create;
Ref.TransformChain.Add(TElXMLBase64Transform.Create());
