hi, Greetings
i am trying to encrypt a file with all restriction.
and also want user to need to type password when open the encrypted pdf..

so i tried..

lngEncID = QPDF.EncodePermissions(0, 0, 0, 0, 0, 0, 0, 0)
QPDF.Encrypt "KamrulHassan", "KamrulHassan", 2, lngEncID

but it's not works; it's ask for the password but there is no restriction

and when i only use master/owner password then restriction works, but not ask the user for password :(

QPDF.Encrypt "KamrulHassan", "", 2, lngEncID

and when i only use user password then restriction does not works, but ask the user for password :(

QPDF.Encrypt "", "KamrulHassan", 2, lngEncID

so, my question is how i can merge both encryption (password and restriction)

please anyone help me out asap

best regards
kamrul hassan

Hi!

Any security setting needs at least and always the main password.
Your problem is here:

Shohag.EncodePermissions...
QPDF.Encrypt...

Try "QPDF.EncodePermissions..." and it will work with
"QPDF.Encrypt..." ;-)

Cheers, Ingo

you don't get it sir, that's just a typing mistake..

because in my coding i used "Shohag" as the variable of libray.. and to make it clear here, i just change the "Shohag" to "QPDF" and forgot to Chane that one :(

how ever thanks for your reply

best regards
