Protecting sensitive information in the real-world is easy. The document could be kept in a secure place, locked in a safe or even hidden under the floor-boards where prying eyes can be kept at bay! You could do the same with an electronic document by moving it to a hard to find location. However, there may be times when you want a document to hand on your desktop or you need to email it to someone you trust while still keep it's contents protected from the outside world...

In Part 1 of this special 2 part Tip, we'll explore how to use OSX's built-in encryption technology to password protect your sensitive PDF documents.

Step 1

Open your PDF document in Preview and choose File > Save as...

Step 2

In the Save as dialog window enable the password feature by clicking on the Encrypt checkbox and type in your password into the text fields provided. Click Save when done.

Step 3

Try opening the PDF in Preview and you be instructed to enter the correct password before being able to view the contents. Your document can only be opened by whoever knows the password. Hmm, now where did I write down that password...

In Part 2 we'll look at how to convert virtually any document or web page into a PDF and of course password protect it!

    In 10.8 Mountain Lion, there is no save as, but there's the option to "export" which you would have the option to choose "encrypt"
