[reportlab-users] Encryption in pdf

[richard at ootbcomputers.com]

It is much better to validate if a user can download the pdf than to encrypt it. Encryption can easily be defeated. Convert to .ps then convert back to pdf works every time.

Hi list,

yesterday I tried to create an encrypted pdf, as stated in paragraph 4

of readme.pdf, but it doesn't work me regarding the options like

canPrint, canCopy, etc.



The output is encrypted and requires a password to be opened (unless i

specifies only the ownerPassword, in this case as stated no password for

opening is required) but I can print and copy from the document



I'm usign reportlab 2.3 on Ubuntu 9.04 (python 2.6 ) and the following

piece of code:



from reportlab.pdfgen import canvas

from reportlab.lib import pdfencrypt

enc=pdfencrypt.StandardEncryption("","owner_pass",canPrint=0,canCopy=0)

def hello(c):

    c.drawString(100,100,"Frase di test che non dovrebbe essere

copiata")

c = canvas.Canvas("test.pdf",encrypt=enc)

hello(c)

c.showPage()

c.save()



I'm wrong using this feature or it is not entirely implemented?



Thanks
