Mobile Security Suite

Welcome to the public beta of the Whisper Systems mobile security suite for Android. We have two applications in the initial beta, RedPhone and TextSecure, which help restore your ability to conduct your personal and business communications privately.

RedPhone 0.1

Encrypted voice for your smartphone.

RedPhone provides end-to-end encryption for your calls, securing your conversations so that nobody can listen in. It's easy to use, and functions just like the normal dialer you're accustomed to. RedPhone uses your normal mobile number for addressing, so there's no need to have yet another identifier or account name; if you know someone's mobile number you know how to call them using RedPhone. And when you receive a RedPhone call your phone will ring just like normal, even if it is asleep.

If you're interested in trying out RedPhone and need someone to call, join #whispersystems on irc.freenode.net

TextSecure 0.3

Encrypted texts for your smartphone.

TextSecure is a drop-in replacement for the standard text messaging application, allowing you to send and receive text messages as normal. All text messages sent or received with TextSecure are stored in an encrypted database on your phone, and text messages are encrypted during transmission when communicating with someone else also using TextSecure.
