[reportlab-users] PDF encryption

[Dinu Gherman]

Hi,

I'm trying to create an "encrypted" PDF in which users can view all 
pages without knowing any password, but perform certain operations only 
when they have the user password. With the code below from the user 
guide (with minimal changes) I can always even view the content only
after entering the user password:

    from reportlab.lib import pdfencrypt
    from reportlab.pdfgen import canvas
    
    enc = pdfencrypt.StandardEncryption("secret",
        canPrint=False, canCopy=False)
    c = canvas.Canvas("hello-enc.pdf", encrypt=enc)
    c.drawString(100, 100, "Hello World")
    c.showPage()
    c.save()

OTOH, the preview of the Python brochure does exactly that, let all 
people see the content, but don't let them copy stuff e.g. without 
a user password. See download on http://brochure.getpython.info

Is there a way to achieve this with reportlab.lib.pdfencrypt?

BTW, there is some space left for a ReportLab ad in the brochure...
;-)

Dinu
