Open Whisper Systems - SMS, Desktop client, IOS and Android

I have been using TextSecure for a few years now. Its an encrypted messaging platform that works via data or SMS. The app can be used to communicate in plain text SMS and as encrypted messages, So you can use the same app when talking to your friends that don’t use TextSecure. Its one of the first crypto tools that has a nice GUI and is simple enough that my non-tech grandparents can use it.

They also have a secure private calling feature and now a desktop client.

Android app

IOS app

Desktop client is in beta

As with all “good” crypto systems the source code is available from github

Here is some plan English description of how the system work

And here is some more detailed description of how it works

@Logan_Buchy brought this up on slack.

TextSecure is what is being used by WhatsApp for secure communication (not available in china or Russia)

And TextSecure isn’t owned by Facebook (whereas WhatsApp is), so I might actually consider using it. :stuck_out_tongue:
