Do not have Protection tool as a part of tasks option or under the tool option seen so I can't encrypt. I have the reader XI

I want to encrypt email attachments.  The tools on the right pane, or under view tools can I get the button of Protection I need to encrypt and set a password for the pdf file.  Why do I not have this option and how do I get it?

Because the Protection is a feature of Acrobat Pro ONLY.

Also encryption is also available in format Acrobat (Standard or Pro) only.
