                  Example Handshake Traces for TLS 1.3
                    draft-ietf-tls-tls13-vectors-02

Abstract

   Examples of TLS 1.3 handshakes are shown.  Private keys and inputs
   are provided so that these handshakes might be reproduced.
   Intermediate values, including secrets, traffic keys and ivs are
   shown so that implementations might be checked incrementally against
   these values.

1.  Introduction

   TLS 1.3 [I-D.ietf-tls-tls13] defines a new key schedule and a number
   new cryptographic operations.  This document includes sample
   handshakes that show all intermediate values.  This allows an
   implementation to be verified incrementally, examining inputs and
   outputs of each cryptographic computation independently.

   Private keys are included with the traces so that implementations can
   be checked by importing these values and verifying that the same
   outputs are produced.

2.  Private Keys

   Ephemeral private keys are shown as they are generated in the traces.

   The server in most examples uses an RSA certificate with a private
   key of:

   modulus (public):  b4bb498f8279303d 980836399b36c698 8c0c68de55e1bdb8

3.  Simple 1-RTT Handshake

   In this example, the simplest possible handshake is completed.  The
   server is authenticated, but the client remains anonymous.  After
   connecting, a few application data octets are exchanged.  The server
   sends a session ticket that permits the use of 0-RTT in any resumed
   session.

   {client}  create an ephemeral x25519 key pair:

      private key (32 octets):  304546ef3c866b23 cc42b5e95282e5df
         16ab583ffd142c40 743dd4f306e67220

         8f14365ec990d575 761e4a6164978d31

   {client}  send a ClientHello handshake message

   {client}  send handshake record:

4.  Resumed 0-RTT Handshake

   This handshake resumes from the handshake in Section 3.  Since the
   server provided a session ticket that permitted 0-RTT, and the client
   is configured for 0-RTT, the client is able to send 0-RTT data.

5.  HelloRetryRequest

   In this example, the client initiates a handshake with an X25519
   [RFC7748] share.  The server however prefers P-256 [FIPS186] and
   sends a HelloRetryRequest that requires the client to generate a key
   share on the P-256 curve.

   {client}  create an ephemeral x25519 key pair:
