New phone who dis: User verification using X.509 certificates
Richard van der Hoff
At Element, we've been thinking about how you can be sure you are chatting to the right person, not an intruder, without reading out numbers or emoji over a video call.
One approach we've been experimenting with is the use of X.509 certificates issued by a trusted certificate authority. I'll be talking about how this helps (and when it doesn't), as well as covering the technical details of the implementation.
