cryptographically invalid sign

Hello,

if I sign a pdf with default configuration with a p12 certificate, the signing process runs without error, but pfd viewer like okular don't accept the signature as cryptographically invalid.

I'm using Rocket Linux and jsignpdf V.2.0.

Any clue?

Thanks

With pdfsig from poppler-utils the signature in your test document is reported valid. The poppler library is the main PDF library used with Okular, but I am using a slightly older version - 0.86.1, which could explain the difference, perhaps.
