Example Handshake Traces for TLS 1.3
Abstract
-
This document includes examples of TLS 1.3 handshakes. 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 of 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.
Note: Invocations of HMAC-based Extract-and-Expand Key Derivation Function (HKDF) [RFC5869] are not labeled, but they can be identified through the use of the labels used by HKDF.
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 data in any resumed session.

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.
Note: The PSK binder uses the same construction as Finished and so is labeled as finished here.

5. HelloRetryRequest
-
In this example, the client initiates a handshake with an X25519 [RFC7748] share. The server, however, prefers P-256 [FIPS.186-4.2013] and sends a HelloRetryRequest that requires the client to generate a key share on the P-256 curve.
Note: The HelloRetryRequest uses the same handshake message type as a ServerHello and so is labeled as ServerHello here. {client} create an ephemeral x25519 key pair: private key (32 octets): 0e d0 2f

6. Client Authentication
-
In this example, the server requests client authentication. The client uses a certificate with an RSA key, the server uses an Elliptic Curve Digital Signature Algorithm (ECDSA) certificate with a P-256 key. Note that private keys for the certificates used in this example are not shown.
{client} create an ephemeral x25519 key pair: private key (32 octets): c0 40 b2 bb 8f 3a dd d2 0f d4 05 8c 54 70 03 a3 c6 f9 c1 cd 91 5d 5e 53 5c 87 d8 d1 91 aa f0 71 public key (32 octets): 08 9c c2

8. Security Considerations
-
It probably isn't a good idea to use the private key included in this document. In addition to the fact that it is too small to provide any meaningful security, it is now very well known.
9. IANA Considerations
-
This document has no IANA actions.
