Abstract:

   This document defines a binary, application-layer transport protocol
   for exchanging Exported Authenticator messages between two peers over
   TLS.  It provides the signaling required to initiate and complete
   post-handshake authentication exchanges at the application layer,
   without requiring modifications to the TLS layer itself.

   While primarily intended to support attestation exchange, the
   transport is generic and can be used independently for any Exported
   Authenticator exchange.

   The document further specifies how protocol messages are conveyed as
   Capsules over an HTTP connection established using the Extended
   CONNECT method, with support for both HTTP/2 and HTTP/3.  In
   addition, it defines how the protocol can operate directly over TLS
   or DTLS 1.3 without an HTTP binding, using a so-called "Shim Mode".
