About this app

Keep your communications secure.

Unbreakable SMS is an SMS/Email/Facebook/Just-about-anything encryption tool. Agree on a password with your friends and use it to send secret messages securely!

This app will detect incoming encrypted messages and fire a notification. You can decrypt messages either directly from your SMS inbox or from the clipboard.

The current supported cryptographic algorithms are:

Morse Code (very weak)

Rail-Fence (very weak)

Rot-13 (very weeak)

Nihilist (weak)

Playfair (medium)

Bifid (medium)

Trifid (medium)

ADFGVX (medium)

AES (very strong)

One Time Pad (Mathematically Unbreakable)

Update: Unbreakable SMS (PAID) is now free! Funny story, that - I forgot my password and couldn't issue updates to the old version anymore. Instead of making everyone buy it again, I decided to just release a free version with all of the same features as the original, plus a few extras.
