Poppler doesn't show digital signatures without visible component
Poppler doesn't recognize digital signatures without visible component (visible signature) It is possible to sign PDF without visible signature and poppler/Okular can't handle that properly
STEPS TO REPRODUCE
- Open digitally signed PDF (make sure there are signatures w/o visible component) or use pdfsig on pdf files
OBSERVED RESULT
- If there's at least one digital signature with visible component poppler will recognize it and will omit all others without visible component
EXPECTED RESULT
- All digital signatures regardless of visible component should be recognized
ADDITIONAL INFORMATION Two attached documents:
- Contract.pdf - 3 digital signatures, none of them with visible component
- The Scrum Guide - 3 digital signatures, 2 with visible component
