The description of Secure Messenger encrypted SMS

Secure Messenger from Chiral Software allows users to send and receive secure text messages over ordinary SMS / MMS. Messages are secured with military-grade 2048-bit public key encryption. Works with any supported phone and any carrier. Messages are secure and cannot be read by carriers, by us, or by any other party. You do not need data service on your phone; only SMS / MMS capabilities are needed.

This app can fully replace the stock/default Android Messaging app as it will also handle regular (non-secure) SMS/MMS messages.

Users interested additional protection may upgrade to a hardware-based key management system available from Chiral Software. We offer a free training session in how to use the app. Please contact us at [email protected] to register.

About Chiral Software, Inc.
We're a small but ambitious cybersecurity R&D lab based in Beverly Hills, California. Secure Messenger is our first app released to the public, however we've already done extensive mobile application and cybersecurity R&D work for government customers like the US Department of Defense.

We take your privacy seriously, simply put: we don't store, track or use any of your information (including your text messages) beyond whatever Google Play (Android Market) does by default. See Google's Privacy Policy for more details:


Both sender and receiver must have Secure Messenger installed.

Step 1: Both users generate keys

Step 2: The two users exchange their keys and save them

Step 3: The users will now be able to communicate securely

Note about PRISM: You may have heard about PRISM, the massive NSA program that monitors and collects all mobile communications in the US, including SMS. Chiral Software's Secure Messenger protects your communications against snooping by PRISM.
