Password protected PDF file

Hello,

Does anyone know how to add a password to a PDF file using Purebasic or is it possible?

Just like the applications Restrict PDF or Adobe Acrobat.

Thank you.

If you are creating the PDF with PB (using PurePDF for example) then you can probably password protect the file by embedding a JavaScript snippet.

@IdeasVacuum:

Thank you for your reply

Is this the same format of javascript to be used?

Code: Select all

<HEAD>
<SCRIPT language="JavaScript">
<!--hide

var password;

var pass1="cool";

password=prompt('Please enter your password to view this page!',' ');

if (password==pass1)
  alert('Password Correct! Click OK to enter!');
else
   {
    window.location="http://www.pageresource.com/jscript/jpass.htm";
    }

//-->
</SCRIPT>
</HEAD>

say i have a file named "jsscript.js" with that code, then will it be just:

Code: Select all

 pdf_IncludeFileJS("C:\Documents and Settings\name\Desktop\jsscript.js")

Regards.

That's how I imagined it, should work. The only snag is that some Anti-Virus apps do not like 'smart' PDF, so people may see an alarming pop-up from the AV.

I tried something like that but it didn't work.

Maybe there's some format for the script to be followed.

Hmm - I had expected a simple Include to work:

Code: Select all

sPdfName.s = "C:\MyPdf.pdf"

pdf_Create("P","mm",#PDF_PAGE_FORMAT_A4)
pdf_AddPage()
pdf_IncludeJS("pass=prompt('enter password',' ');if(pass=='secret')alert('OK');")
pdf_Save(sPdfName)

.....The file is created without complaint, but the javascript does not execute on file open.

I assume this must be a syntax issue, ABBKlaus will know, but this post needs to be in the PurePDF posts.
