How to encrypt SD card contents on Android?

I’m not too worried about the contents on my Android phone - I use a strong lock pattern, and have it setup so I can remotely wipe it using Google Android Account manager. But what about the SD card? Is there a way to remote wide it or encrypt the SD card contents so they are not exposed if my device is lost or stolen?

"Your Android device is a pocket-size container of important information that you don’t want to fall into the wrong hands. Think of your emails, SMS messages, contacts, credit card numbers, files, photos, etc. being exposed to someone who whether by intent or by accident got a hold of your Android phone or tablet.

No one wants to be in that vulnerable scenario. That’s why you can lock down your Android device with a combination of protective security measures, one of which is encryption, a pretty important one.

This is easy to accomplish, and you already have all of the tools on your device. I can’t remember which was the first version of Android to support it, but if you go into your security settings then “encryption”, there should be an option to encrypt your SD card. You do have to use a password (I think that a lock pattern will work as well), which makes sense. It can take a while to encrypt all of the contents of a large SD card, so if you choose to encrypt everything be patient. Also, DO NOT FACTORY RESET WITH YOUR SD CARD ENCRYPTED! You will not be able to regain access if you do.
