Signal Private Messenger is an open-source, end-to-end encrypted messaging application that allows users to communicate securely and privately over the internet. Developed by the Signal Technology Foundation and Signal Messenger LLC, Signal is designed with a strong focus on privacy, security, and ease of use. In this guide, we will provide an in-depth overview of Signal, its features, and its importance in the realm of secure communication.

History and Development of Signal

Signal was created by Moxie Marlinspike, a renowned security researcher, and cryptographer, and Brian Acton, the co-founder of WhatsApp. The development of Signal began in 2010, with the launch of TextSecure, an encrypted messaging app for Android. In 2013, Marlinspike’s company Whisper Systems was acquired by Twitter, and the TextSecure protocol was later released as open-source.

In 2014, Marlinspike founded Open Whisper Systems, which developed the RedPhone app for encrypted voice calls. Later, TextSecure and RedPhone were combined into a single app, Signal, which was released for Android and iOS devices in 2015. In 2018, the Signal Foundation was established with a $50 million investment from Brian Acton, with the goal of supporting the development and maintenance of the Signal app and its underlying technology.
