Meet DAVE: Discord’s New End-to-End Encryption for Audio & Video

We’re rolling out end-to-end encryption for voice and video calls! We’d like to share why we’re bringing E2EE A/V to Discord, share our design and implementation goals, and provide a high-level technical overview of how it works.

@evacide But how can you be sure it’s actually E2E?
@frumble @evacide de- and encryption, happens on the device/in the browser using web apis, so you can just look at traffic arriving at and leaving the browser.
@u1l @evacide But on mobile devices? And how can you discern between E2EE and regular transport encryption?

@frumble @evacide They're publishing tech reviews :-

"In the past few months, we collaborated closely with Trail of Bits, a renowned independent cybersecurity firm, to conduct a thorough review of both the design and implementation of DAVE in our code base. With DAVE’s launch, Trail of Bits is publishing their findings from both the design review and implementation review."

You have to decide whether to trust the reviewer of course, and to trust that what was reviewed is what you're using today.
