   This document provides usage guidance for external Pre-Shared Keys
   (PSKs) in Transport Layer Security (TLS) version 1.3 as defined in
   RFC 8446.  It lists TLS security properties provided by PSKs under
   certain assumptions and demonstrates how violations of these
   assumptions lead to attacks.  It discusses PSK use cases,
   provisioning processes, and TLS stack implementation support in the
   context of these assumptions.  It provides advice for applications in
   various use cases to help meet these assumptions.  It also lists the
   privacy and security properties that are not provided by TLS when
   external PSKs are used.
