ADDITIONAL INFORMATION
Comment 1 Albert Astals Cid 2020-03-16 22:57:19 UTC 
This is again a problem of missing features in poppler.

poppler does not extract those certificates from the PDF file so we can't show the chain.

Could you please open a bug in https://gitlab.freedesktop.org/poppler/poppler/issues  ?
