| artifexirc-bot | <xx> I have a cryptographically signed PDF using the algorithm defined in the PDF standard, and would like to display information about this signature such as the certificate chain, fingerprints, etc. `pdfsig file.pdf` only shows minimal info | 15:04.37 |
| | <KenSharp> So a digital signature ? Ghostscript ignores those | 15:05.09 |
| | <KenSharp> You would be beter using MuPDF I suspect | 15:05.40 |
| | <xx> mutool perhaps? | 15:24.21 |
| | <KenSharp> To be honest I don't think any of the tools will give you what you want 'out of the box' but I think MuPDF plus scripting (JS) might be able to. You'd do better to ask in the #mupdf channel, I am not a MuPDF expert at all | 15:25.26 |
| | <xx> thanks, didn't know about that channel | 15:25.43 |
| | <KenSharp> Also since MuPDF can sign PDF files, they probably know more about digital signatures than me 🙂 | 15:25.53 |
| | <xx> :) | 15:26.00 |
