Be able to certify and sign document

[Mathieu Piot]

Actually open-pdf-sgin is able to "certify" a document, it should be interesting to be abble to "sign" a document to. Maybe add an option like: --type certify|sign

So when we open a PDF document, in the Signature Panel, we have control on:

• Signed by...
• Certified by...

Hi @mpoit,

thank you for the issue!

From what I understand, this basically is possible by not specifying a permission. E.g. not specifying results in a document like signed-signature.pdf

It probably makes sense to combine this issue and #47 into a single parameter, allowing either setting no restriction (=signing) or a specific restriction (instead of the current minimal_changes_permitted). I'll look into that.

@cproof Ooohhh, I've look at the EuDSS documentation to find something about that, but not found 😅

Your idea is really better because it can be interesting to choose between the 3 options 👍

Thanks for your answer

Fixed in v0.1.6, using --certification not-certified for "signing".
