Remarks The PDF specification for signatures uses data present in a partially written PDF file to
create a data hash to verify that a document is consistent with its state when it was signed. Under
certain conditions, it may be impossible to retain this ability. Generally speaking, DotPdf will
completely rewrite a file when saving and this will invalidate any and all signatures in the file
