Very cool Make your password unbreakable just like C.I.A. or F.B.I.

Useful app 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.

Won't work on newer devices Not usable for newer devices, the program works but is dependant upon a 'menu' button found on older devices only. The newer design philosophy of Android has done away with this particular affectation, doing it via software (the three squares on the lower right hand corner usually, but not always) but this hasn't been updated to support that. Newer devices will only see "No ciphers found" and no way to add any. Unfortunate, this looked promising to me. It might be easily updatable however. Or so I surmise.
