SRP is very a very clever protocol.
I appreciate the many security layers, including this interesting one, that you offer.
After reading your white paper, I did some more reading and discovered that there's a somewhat new PAKE called OPAQUE that has one unique advantage over SRP in that the salt is not revealed, thus preventing pre-computation attacks.
Additionally, SRP, as I understand it, is not supported in (the current version of) TLS 1.3.
Just curious, for my understanding, what do you think about OPAQUE? Is this something you are considering for the future and what do you think about TLS 1.3 apparent incompatibility with SRP?
