TextSecure

TextSecure was an encrypted messaging application for Android that was developed from 2010 to 2015. It was a predecessor to Signal and the first application to use the Signal Protocol, which has since been implemented into WhatsApp and other applications. TextSecure used end-to-end encryption to secure the transmission of text messages, group messages, attachments and media messages to other TextSecure users.

TextSecure was first developed by Whisper Systems, who were later acqui-hired by Twitter. The application's source code was then released under a free and open-source software license. In 2013, TextSecure's development was picked up by an independent group called Open Whisper Systems, who merged it with an encrypted voice calling application called RedPhone and renamed the product as Signal.
