Thank you for answering.
I see that I haven't being specific in my question, so I need to elaborate.
This PDF files I mentioned, I opt to send them by mail to other people that only do windows. Also I prefer to encrypt the pdf file itself (opposed to zip it) just because it's less chance that the file will be laying around in an unencrypted state on somebody's windows computer.That is - I assume for a zip-package, it's pretty normal that the casual receiver just unpack it, leaving the unencrypted file to their own companys file server for anyone to read.
So my goal is to try to prevent other people on the receiver end full access to the file.

I won't let an old, but fully functional computer die just because some company tell me that they won't make no more security updates to their OS. Thanks Linux
