I use the method mentioned here "Is there a package to secure rendered pdf with a password?".
\special{pdf:encrypt ownerpw (abc) userpw (xyz) length 128 perm 2052}
\documentclass{article}
\begin{document}
This is a test.
\end{document}
Tested:
Win7 64bit + MiKTeX 2.9 32bit
Did not use the owner password "abc" to encrypt the pdf, but the user password "xyz" by setting.
