In Latex try:

\pdfcrypt{none} 

in the preamble, to really annoy everyone!

I think the syntax has changed from my out-of-date version of pdftex,
but the options used to be:
<<	owner "me" 
	user "you" 	
	print noprint copy nocopy 
	edit noedit annotate noannotate all none		>>
where me and you are passwords.

A search for "pdfcrypt" should find syntax to match your pdftex version.

Quick test of whether it is working is File / Document Info / Security
from the Acrobat menu bar.


BTW
Acrobat 4.0 for Linux will _not_ print out files if I use pdfcrypt (even if 
"deny all but allow printing").
A simple command line "lp file.pdf" will print them (unless printing is 
disallowed).
But I still have to upgrade ....

PS pdfcrypt is the work of Ricardo Carmenes.
