Aims and Scope

This book provides a comprehensive treatment of end-to-end encrypted (E2EE) messaging as it is currently used on the Internet. It starts with OpenPGP and S/MIME, elaborates on OTR, and then mainly addresses Signal, the use of Signal in WhatsApp and a few other E2EE messengers (e.g., Viber, Wire, and Rot), as well as E2EE messengers that are widely deployed but don't use the Signal protocol, such as iMessage, Wickr, Threema, and Telegram. The book also outlines privacy issues and standardization.

Target Audience

The book is intended for anyone who wants to understand what end-to-end encrypted (E2EE) messaging is and how it is implemented on the Internet. It speaks to theorists and practitioners.
