Script to save pdf with password

Hello,

I would really appreciate a script that can save the current file as pdf with password.

What I do normally is this:

1- Save as.

2- PDF Format.

3- Save in the same location as the original file.

4- Adobe PDF Preset: Smallest File Size

5- Go to "Security" then "Use a password to restrict..."

6- Set Password

    Done.

I found this script in another thread on this forum:

var pdfFile = new File(app.activeDocument.fullName.toString().replace(".ai",".pdf"));  
var saveOpts = new PDFSaveOptions(); //You can set PDF SaveOptions like below properties...    
saveOpts.PDFXStandard = 2; //X1a 2001  
app.activeDocument.saveAs (pdfFile, saveOpts);  

Could this be modified to my needs?

Thanks!
