   I mean cryptographically sign, with a legally valid certificate.   
      
   PGP is not legally valid. PKCS is. Imposing a graphic of your written   
   signature is not, but can pass sometimes.   
      
   You can download a sample signed document here:   
      
      
      
   or   
      
   wget https://blogs.adobe.com/security/SampleSignedPDFDocument.pdf   
      
      
   Open it with Okular. You will see a message banner on top saying that   
   the document is digitally signed. Now try to sign a PDF in Linux like   
   that. LibreOffice can do it.
