Example Handshake Traces for TLS 1.3
draft-ietf-tls-tls13-vectors-04
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 [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.
A private key is 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:

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:

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:

6. Client Authentication
In this example, the server requests client authentication. The
client uses a certificate with an RSA key, the server uses an ECDSA
certificate with a P-256 key. Note that private keys for this
example are not included in the draft.
