I'm not sure how much we can do with this as this is how System.IO.Packaging
writes it out. I've recently inserted an abstraction between the main SDK and System.IO.Packaging, but we still rely on this behavior.
For background, the cloning is done by loading things and writing out to a new package. They are semantically cloned, but as you see, they do not have the same exact structure so signatures would not work. If that is necessary, I'd suggest clone them at the stream/file level first.
Describe the bug Cloning a package via
OpenXmlPackage Clone(Stream stream)
method breaks digital signatures.Screenshots
To Reproduce
Steps to reproduce the behavior:
.docx
file using Microsoft Word and add digital signature or signature line and sign it.WordprocessingDocument
andClone
into new file.Observed behavior Some XML parts gets reordered,
/
added toTarget
attribute inRelationship
URIs,standalone
XML declaration is added some parts.Expected behavior No changes should happen in part that are used in signature digests.
