[pdftex] ID string in final PDF vs. same PDF checksum for same inputs

Dear PdfTEX Developers,

I am currently trying to create PDFs with the same checksum for the same inputs.

Apparently [1, own tests] the “ID” string in the PDF avoids this. 

Is there any way to, e.g., set this string to a constant value or leave it out?

Thank you, Kind regards
Quirin
