Does Zoom use end-to-end encryption? – A Few Thoughts on Cryptographic Engineering

Clarity that under certain conditions Zoom is end-to-end encrypted. Certain features disable that. Zoom could definitely do a better job showing the user what the status of any given meeting is.

What Zoom needs now is to very rapidly deploy a new method of agreeing on cryptographic session keys, so that only legitimate participants will have access to them. Fortunately this “group key exchange” problem is relatively easy to solve, and an almost infinite number of papers have been written on the topic.

I think this is accurate. Recent hires and Zoom's commitment to focus only on security for the next 90-days should result in a good result.
