Act on PDF's properties



-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hi,

I have a PDF document that I want to lock for some features, such as
content extraction, and printing. I know that these locks can be
bypassed, but I also know that the persons I am going to send the PDF
to are completely unaware of the existence of any way to bypass a PDF.

How can I lock it? (I.e. which tool can I lock it with?)

Thanks.
