PDF Security II

Question

Hello all, I was reading a post about pdf security and the following script, created by Mike Brog, was mentioned. However, I do not know how to modify it to work for me. I am very new to scripting. Some of the elements look familiar to me, but I still do not know what to modify.
I should clarify that I need the script to export a pdf with the security settings already applied.
I have replied to the original post but thought I would get a better response by making a new post.
Thanks Tom

As Mylenium said once a PDF file's been created with a password, it cannot be cracked. You need to check with the creator of the file for its password.
