Can wicked_pdf or wkhtmltopdf generate a protected pdf?

问题

So, I have wicked_pdf up and running, now I am wondering if I can password protect the pdf being generated so it is not easily editable. Is this possible? Perhaps a better question is can wkhtmltopdf generate a protected pdf?

If not, is there a great rails pdf gem or similar that can take an existing pdf and protect it?

Thanks!

Let me check the usage for wkhtmltopdf (v0.10.0 rc2).

Nope, at least not according to it's usage dump. And wicked_pdf just wraps wkhtmltopdf, so you're out of luck.

There are any number of OSS PDF projects floating around out there that could encrypt your PDF output in a second pass.
