How do I certify a document so it can run privileged javascript?

Hi, the acrobat javascript api reference says that functions marked with a red S can be run in document-level javascript, "provided the certifier’s certificate is trusted for running embedded high privilege JavaScript". What do I need to do to create documents with that trusted certificate?

You can do so via Tools - Protection - Encrypt - Encrypt with Certificate.

Thanks. If I do that, can anyone still open the document, or only people specifically added as recipients via the encryption wizard?
