On 2024-11-16 at 19:55:52 UTC-0500 (Sat, 16 Nov 2024 18:55:52 -0600) Michael Rathbun via mailop <[email protected]<mailto:[email protected]>> is rumored to have said: I confess to being completely mystified. What is the nature of these TLS reports, and where do they come from? Presumably RFC8460 https://datatracker.ietf.org/doc/html/rfc8460<https://urldefense.com/v3/__https:/datatracker.ietf.org/doc/html/rfc8460__;!!CQl3mcHX2A!EGwRpqowIJPd9pqE6Cin4r4Hv6jCW75lWyXx3M9rCFFBBiMoR_agpPuN1awTjG0Vhn6UIzftc7Rs_NsTEx0$>. Intimately related to MTA-STS, RFC8461. It can also be used with DANE, but I don't know of anyone doing so.
