This document describes universal PSKs (Pre-Shared Keys) for TLS. Universal PSKs abstract the TLS 1.3 requirement that each PSK can only be used with a single hash function. This allows PSKs to be provisioned without depending on details of the TLS negotiation, which may change as TLS evolves. Additionally, this document describes a compatibility profile for using TLS 1.3 with PSKs provisioned for the TLS 1.2 PSK mechanism.
