using javascript to password protect pdf

Question

How do I password protect a pdf using javascript? I know it's possible to apply a security policy to a pdf with javascript, but how can I get access to the login username and password?

Answer 1

You can definitely use Javascript to manipulate your .pdf's ... as long as you're using Acrobat Reader. I've used it to do bookmarks; I imagine you can also support username/password operations.

Here's the official documentation:
