Hi Ril,

Is there a way to have my macros digitally signed programmatically
(i.e. at the point when the workbook is being created by the Delphi
code)?

One way is to start with an empty, signed, workbook, then provide the
name of that workbook to the Workbooks.Add method. You can then add
code to that workbook and save it, keeping the signature.
