Earlier this month, Justin Hendrix traveled to RightsCon, the big gathering of individuals and organizations concerned with human rights and technology organized by Access Now. The sprawling event had hundreds of sessions on a wide range of themes, but one topic discussed across multiple tracks was the importance of encrypted communications, especially to groups such as political dissidents and journalists.

A key panel at RightsCon featured Signal President Meredith Whittaker, who spoke out about policies proposed in legislatures around the world that threaten the promise of end-to-end encryption to preserve the privacy of messages sent between individuals and groups. Leaders of encrypted apps have pulled together of late to speak out against the proposed UK Online Safety Bill, signing letters and appearing at events. Shortly after RightsCon, Hendrix connected with Whittaker to learn more about Signal’s posture against such legislation, why she sees encrypted communications as so crucial to freedom and human rights, and how the company thinks about safety and its role in the broader digital ecosystem.
