Updated Review: Reinstalled the application upon hearing it was updated for holo designed devices (it required a menu button previously, a lot of newer devices don't have physical menu buttons anymore). This does exactly I was hoping it would, really like the fact it uses share functionality of android as opposed to just SMS, so you can use the encryption in any app that also uses the share functionality. If it doesn't you can cut-n-paste, but share is so much easier.

So far this utility seems to work just fine.
