Hi all, I have captured in a draft the mechanism I used during IETF 103 hackathon and which is available aan experimental module in knot-resolver[0]. I was taken short with time before cit-off date, but I hope this will better explain how it works.

The fingerprint can thereafter be used to validate the certificate received from the DoT server as well as being able to discover support for DoT on the server. Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org. The IETF Secretariat
