Java Script to Save ai to PDF with password...

Hi folks.  My goal is to have a script carry out the following functions:

1. grab the active document name

2.  save as a PDF using the active doc name with password lock in the same directory the *.ai file is located

I have started fiddling with some code but I don't know what I'm doing...newbie.

Here is the code I'm currently using.

var curDoc = app.activeDocument;
var destFolder, sourceFolder, files, fileType, sourceDoc, targetFile, pdfSaveOpts;
//var destName = "~/Desktop/Testpassword1.pdf";
var destName = targetFile
saveFileToPDF(destName);
//sourceFolder = Folder.selectDialog( 'Select the folder with Illustrator files you want to convert to PDF', '~' );
//saveFileToPDF(destName);
//+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
if ( sourceFolder != null )
{
    //files = new Array();
    //fileType = '*.ai';
    //fileType = prompt( 'Select type of Illustrator files to you want to process. Eg: *.ai', ' ' );
    
    // Get all files matching the pattern
    //files = sourceFolder.getFiles( fileType );
    
    if ( files.length > 0 )
    {
        // Get the destination to save the files
        destFolder = Folder.selectDialog( 'Select the folder where you want to save the converted PDF files.', '~' );
        for ( i = 0; i < files.length; i++ )
        {
            sourceDoc = app.open(files); // returns the document object
                                    
            // Call function getNewName to get the name and file to save the pdf
            targetFile = getNewName();
            
            // Call function getPDFOptions get the PDFSaveOptions for the files
            //pdfSaveOpts = getPDFOptions( );
            
            // Save as pdf
            sourceDoc.saveAs( targetFile, pdfSaveOpts );
            
            sourceDoc.close();
        }
        alert( 'Saved' + destFolder );
    }
    else
    {
        alert( 'No matching files found' );
    }
}

 function getNewName()
{
    var ext, docName, newName, saveInFile, docName;
    docName = sourceDoc.name;
    ext = '.pdf'; // new extension for pdf file
    newName = "";
        
    for ( var i = 0 ; docName != "." ; i++ )
    {
        newName += docName;
    }
    newName += ext; // full pdf name of the file
    
    // Create a file object to save the pdf
    saveInFile = new File( destFolder + '/' + newName );
    

    return saveInFile;
}
